Balloon Valvuloplasty: Widening of a stenosed HEART VALVE by the insertion of a balloon CATHETER into the valve and inflation of the balloon.Catheterization: Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.Pulmonary Valve Stenosis: The pathologic narrowing of the orifice of the PULMONARY VALVE. This lesion restricts blood outflow from the RIGHT VENTRICLE to the PULMONARY ARTERY. When the trileaflet valve is fused into an imperforate membrane, the blockage is complete.Mitral Valve Stenosis: Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.Aortic Valve Stenosis: A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.Rheumatic Heart Disease: Cardiac manifestation of systemic rheumatological conditions, such as RHEUMATIC FEVER. Rheumatic heart disease can involve any part the heart, most often the HEART VALVES and the ENDOCARDIUM.Pulmonary Valve: A valve situated at the entrance to the pulmonary trunk from the right ventricle.Atrial Septum: The thin membrane-like muscular structure separating the right and the left upper chambers (HEART ATRIA) of a heart.Tricuspid Valve Stenosis: The pathologic narrowing of the orifice of the TRICUSPID VALVE. This hinders the emptying of RIGHT ATRIUM leading to elevated right atrial pressure and systemic venous congestion. Tricuspid valve stenosis is almost always due to RHEUMATIC FEVER.Mitral Valve: The valve between the left atrium and left ventricle of the heart.Aortic Valve: The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.Cardiac Catheterization: Procedures in which placement of CARDIAC CATHETERS is performed for therapeutic or diagnostic procedures.Follow-Up Studies: Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.Cyanosis: A bluish or purplish discoloration of the skin and mucous membranes due to an increase in the amount of deoxygenated hemoglobin in the blood or a structural defect in the hemoglobin molecule.Hemodynamics: The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM.Angioplasty, Balloon: Use of a balloon catheter for dilation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of BALLOON DILATION in coronary arteries, ANGIOPLASTY, BALLOON, CORONARY is available.Heart Valve Prosthesis Implantation: Surgical insertion of synthetic material to repair injured or diseased heart valves.Echocardiography: Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.Balloon Occlusion: Use of a balloon CATHETER to block the flow of blood through an artery or vein.Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Infant, Newborn: An infant during the first month after birth.Recurrence: The return of a sign, symptom, or disease after a remission.Angioplasty, Balloon, Coronary: Dilation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply.Intra-Aortic Balloon Pumping: Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.Gastric Balloon: An inflatable device implanted in the stomach as an adjunct to therapy of morbid obesity. Specific types include the silicone Garren-Edwards Gastric Bubble (GEGB), approved by the FDA in 1985, and the Ballobes Balloon.Prospective Studies: Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group.Aortic Valve Prolapse: The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.Mitral Valve Insufficiency: Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.Fetal Therapies: Prenatal interventions to correct fetal anomalies or treat FETAL DISEASES in utero. Fetal therapies include several major areas, such as open surgery; FETOSCOPY; pharmacological therapy; INTRAUTERINE TRANSFUSION; STEM CELL TRANSPLANTATION; and GENETIC THERAPY.Venous Insufficiency: Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.Heart Valve Prosthesis: A device that substitutes for a heart valve. It may be composed of biological material (BIOPROSTHESIS) and/or synthetic material.Pregnancy Complications, Cardiovascular: The co-occurrence of pregnancy and a cardiovascular disease. The disease may precede or follow FERTILIZATION and it may or may not have a deleterious effect on the pregnant woman or FETUS.Hypoplastic Left Heart Syndrome: A condition caused by underdevelopment of the whole left half of the heart. It is characterized by hypoplasia of the left cardiac chambers (HEART ATRIUM; HEART VENTRICLE), the AORTA, the AORTIC VALVE, and the MITRAL VALVE. Severe symptoms appear in early infancy when DUCTUS ARTERIOSUS closes.Echocardiography, Doppler: Measurement of intracardiac blood flow using an M-mode and/or two-dimensional (2-D) echocardiogram while simultaneously recording the spectrum of the audible Doppler signal (e.g., velocity, direction, amplitude, intensity, timing) reflected from the moving column of red blood cells.Echocardiography, Transesophageal: Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues using a transducer placed in the esophagus.Pulmonary Atresia: A congenital heart defect characterized by the narrowing or complete absence of the opening between the RIGHT VENTRICLE and the PULMONARY ARTERY. Lacking a normal PULMONARY VALVE, unoxygenated blood in the right ventricle can not be effectively pumped into the lung for oxygenation. Clinical features include rapid breathing, CYANOSIS, right ventricle atrophy, and abnormal heart sounds (HEART MURMURS).Aortic Valve Insufficiency: Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).Femoral Vein: The vein accompanying the femoral artery in the same sheath; it is a continuation of the popliteal vein and becomes the external iliac vein.Noonan Syndrome: A genetically heterogeneous, multifaceted disorder characterized by short stature, webbed neck, ptosis, skeletal malformations, hypertelorism, hormonal imbalance, CRYPTORCHIDISM, multiple cardiac abnormalities (most commonly including PULMONARY VALVE STENOSIS), and some degree of INTELLECTUAL DISABILITY. The phenotype bears similarities to that of TURNER SYNDROME that occurs only in females and has its basis in a 45, X karyotype abnormality. Noonan syndrome occurs in both males and females with a normal karyotype (46,XX and 46,XY). Mutations in a several genes (PTPN11, KRAS, SOS1, NF1 and RAF1) have been associated the the NS phenotype. Mutations in PTPN11 are the most common. LEOPARD SYNDROME, a disorder that has clinical features overlapping those of Noonan Syndrome, is also due to mutations in PTPN11. In addition, there is overlap with the syndrome called neurofibromatosis-Noonan syndrome due to mutations in NF1.Endocardial Fibroelastosis: A condition characterized by the thickening of ENDOCARDIUM due to proliferation of fibrous and elastic tissue, usually in the left ventricle leading to impaired cardiac function (CARDIOMYOPATHY, RESTRICTIVE). It is most commonly seen in young children and rarely in adults. It is often associated with congenital heart anomalies (HEART DEFECTS CONGENITAL;) INFECTION; or gene mutation. Defects in the tafazzin protein, encoded by TAZ gene, result in a form of autosomal dominant familial endocardial fibroelastosis.Postoperative Complications: Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.Mitral Valve Annuloplasty: A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annulus of the MITRAL VALVE. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.Time Factors: Elements of limited time intervals, contributing to particular results or situations.Bioprosthesis: Prosthesis, usually heart valve, composed of biological material and whose durability depends upon the stability of the material after pretreatment, rather than regeneration by host cell ingrowth. Durability is achieved 1, mechanically by the interposition of a cloth, usually polytetrafluoroethylene, between the host and the graft, and 2, chemically by stabilization of the tissue by intermolecular linking, usually with glutaraldehyde, after removal of antigenic components, or the use of reconstituted and restructured biopolymers.Retrospective Studies: Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.Angioplasty, Balloon, Laser-Assisted: Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.Pulmonary Valve Insufficiency: Backflow of blood from the PULMONARY ARTERY into the RIGHT VENTRICLE due to imperfect closure of the PULMONARY VALVE.Heart Defects, Congenital: Developmental abnormalities involving structures of the heart. These defects are present at birth but may be discovered later in life.Atrial Function, Left: The hemodynamic and electrophysiological action of the LEFT ATRIUM.Fetoscopy: Endoscopic examination, therapy or surgery of the fetus and amniotic cavity through abdominal or uterine entry.Double-Balloon Enteroscopy: Endoscopy of the small intestines accomplished while advancing the endoscope into the intestines from the stomach by alternating the inflation of two balloons, one on an innertube of the endoscope and the other on an overtube.Mitral Valve Prolapse: Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.

Hypoplastic right-heart syndrome presenting as multiple miscarriages. (2/32)

Reversible causes of miscarriage are many, but they affect only 1% of women who are trying to conceive. Herein, we describe the case of a 23-year-old woman who presented for evaluation of repeated miscarriages and was found to have hypoxemia and erythrocytosis. Further evaluation revealed hypoplastic right-heart syndrome with an intracardiac shunt. She underwent hybrid repair with pulmonary valve balloon valvuloplasty, followed by surgery to perform atrial septal defect closure and a Glenn anastomosis. The erythrocytosis and hypoxemia resolved, and she was able to conceive and deliver a healthy baby at term 2 years later. This is a unique case of a rare congenital heart defect that went unnoticed until adulthood, when attempts at pregnancy failed because of the associated hypoxemia. Timely and appropriate treatment led to a successful pregnancy after repeated miscarriages. This case exemplifies the need for a comprehensive medical evaluation of every woman with a history of multiple miscarriages to determine whether a reversible cause exists.  (+info)

The accuracy of three-dimensional echocardiography with multiplanar reformatting in the assessment of the aortic valve annulus prior to percutaneous balloon aortic valvuloplasty in congenital heart disease. (8/32)

OBJECTIVE: To review the use of three-dimensional echocardiography (3DE) with multiplanar reformatting (MPR) in children with congenital aortic stensosis undergoing percutaneous balloon aortic valvuloplasty to assess its accuracy in measuring the aortic valve annulus and any influence it may have on balloon sizing. METHODS: All percutaneous aortic balloon valvuloplasties performed from 01/01/2009 to 01/09/2011 were included in the study. All imaging performed for the procedure to determine the size of the aortic valve annulus and aid in balloon sizing was reviewed. The maximum diameter of the aortic valve annulus using two-dimensional echocardiography (2DE), 3DE with MPR, and angiography was recorded. The balloon size used in the procedure was recorded and the balloon to annulus ratio was calculated. RESULTS: A total of 27 procedures were included in the study. Age varied from 1 day to 156 months (mean age, 53 months) and weight from 2.8-58 kg (mean weight, 18.6 kg). Fourteen patients had 3DE with MPR available for analysis. The 3DE with MPR measurement (13.36 +/- 5.4 mm) was not different from angiography (13.54 +/- 6.4 mm; P=.803).The 2DE measurement was significantly different from angiography (11.72 +/- 5 mm; P<.005). The balloon to annulus ratio based on angiographic measurements did not differ significantly between the patients with 3DE MPR and those without (0.94 +/- 0.095 vs 0.91 +/- 0.1; P=.468). CONCLUSION: 3DE with MPR allows a more accurate assessment of the aortic valve annulus compared to 2DE, which may reduce the tendency to undersize balloon choice. 3DE with MPR did not significantly affect our balloon choice, which was largely based on angiographic measurements.  (+info)

The results of this trial indicate that among patients with severe degenerative aortic stenosis with mostly low STS PROM scores, TAVR with the CoreValve self-expanding prosthesis results in similar 1-year clinical outcomes as SAVR. Stroke risk was similar as well. SAVR resulted in more bleeding complications and atrial fibrillation, while TAVR patients had more aortic regurgitation, less symptomatic benefit, and a higher need for a permanent pacemaker.. Currently, in the United States, TAVR is approved for high-risk (STS PROM ≥8%) and inoperable patients only. Intermediate-risk trials with both balloon-expandable and self-expanding TAVR valves are ongoing. Although this trial is relatively small, the results are fairly interesting. At a broad level, both strategies appear to perform similarly, even in low-risk patients. However, patients in the TAVR arm had higher aortic regurgitation and permanent pacemaker requirements; the impact of these findings on long-term outcomes is unclear. Also, ...

Even in my relatively short consultant career the pattern of clinical work has changed significantly. The coronary intervention I perform is now almost exclusively for acute coronary syndromes and particularly STEMI. I review and report more aortic CT scans than coronary angiograms and I now participate in multiple sub-specialty heart team MDT meetings a week. I have performed increasing numbers of elective aortic valve interventions (TAVI and balloon aortic valvuloplasty) year on year (135 in 2014) with a projected growth of 20% per annum. Our centre is now the largest trans-catheter valve implanting centre in the UK and we are constantly trying to innovate to improve patient outcome using novel valve technologies, cerebral protection devices, alternate vascular access and non-GA procedures ...

Title: Mitral Balloon Valvuloplasty: State-of-the-Art Paper. VOLUME: 2 ISSUE: 1. Author(s):Mohamed E. Fawzy. Affiliation:Consultant, Adult Cardiology,King Faisal Heart Institute (MBC-16), King Faisal Specialist Hospital&Research Center, PO Box 3354, Riyadh 11211, Saudi Arabia.. Keywords:Mitral valve, mitral stenosis, valvuloplasty. Abstract: Percutaneous mitral balloon valvuloplasty (MBV) was introduced in 1984 by Inoue who developed the procedure as a logical extension of surgical closed commissurotomy. Since then, MBV has emerged as the treatment of choice for severe pliable rheumatic mitral stenosis (MS). With increasing experience and better selection of patient, the immediate results of the procedure have improved and the rate of complications declined. When the reported complications of MBV are viewed in aggregate, complications occur at approximately the following rates: mortality (0% to 0.5%), cerebral accident (0.5% to 1%), mitral regurgitation (MR) requiring surgery (2% to 3%). These ...
TY - JOUR. T1 - Balloon valvuloplasty.. AU - Bourdillon, P.. AU - Dillon, J.. AU - Brown, S.. AU - Feigenbaum, H.. PY - 1990/10/1. Y1 - 1990/10/1. N2 - Percutaneous balloon valvuloplasty has been used for several years for the treatment of stenosis of all four cardiac valves. It has been particularly effective in pulmonary stenosis in children and in rheumatic mitral stenosis, especially in the younger age groups without severe calcification. After initial enthusiasm, results have not been as good in severe calcific aortic stenosis, although there is a place for aortic valvuloplasty in patients who are truly inoperable for reasons of age or coexisting disease. The procedure also may be applicable to occasional cases of tricuspid stenosis. The techniques used and results obtained with these procedures at Indiana University are described.. AB - Percutaneous balloon valvuloplasty has been used for several years for the treatment of stenosis of all four cardiac valves. It has been particularly ...
The purpose of this study was to compare contemporary results of balloon dilatation and surgery for valvar aortic stenosis in infants and children in the five years between August 1988 and October 1993. Thirty four children underwent attempted balloon valvuloplasty (age 1 day-16 years, weight 1720 g-68 kg) (group 1), eight of whom were neonates with critical aortic stenosis. During the same period, 17 children underwent direct surgical valvotomy (group 2) (seven neonates). Successful balloon valvuloplasty was achieved in 33 (97%) with immediate reduction in the instantaneous systolic pressure gradient from 82 to 34 mm Hg (mean). There were two deaths in this group (both neonates), the second in a preterm neonate from necrotising enterocolitis. Complications requiring intervention in group 1 were aortic regurgitation in one and femoral artery injury in two. Follow up from four months to five years showed sustained results in most cases. There were two neonatal deaths in the surgical group. When ...
A 4-year old male miniature schnauzer with severe pulmonic stenosis was presented for percutaneous balloon valvuloplasty. The dog had been managed medically with atenolol for a month prior to the procedure. Clinical examination was unremarkable except for auscultation of a grade V/VI left-sided systolic murmur. The dog was premedicated with pethidine. Anaesthesia was induced using diazepam and etomidate and maintained using sevoflurane in oxygen. Angiography was uneventful, but when the guidewire was threaded through the right side of the heart to allow insertion of the balloon catheter, marked desaturation with visible cyanosis developed. This resolved on withdrawal of the guidewire and catheter but recurred each time the guidewire and catheter were repositioned. Balloon valvuloplasty was eventually successful in reducing the pressure gradient across the stenotic valve from 102 to 52 mmHg. Hypoxaemia did not recur during recovery and the dog was discharged the following day.. ...

A 38-year-old male with previous surgeries for an incomplete atrioventricular septal defect successfully underwent percutaneous transcatheter tricuspid balloon valvuloplasty for a deteriorated bioprosthetic valve. Our case highlights the imperative of considering catheter-based minimally invasive therapy for the increasing number of adults with congenital heart disease who may present multiple risks factors for surgery.
Congenital pulmonary stenosis balloon valvuloplasty is a procedure that aims to fix pulmonary valve that doesn’t fully open. It does so without the need for open heart surgery.
Dr. Dangas noted, "Technologies to enable heart valve replacement or repair without cracking open a patients chest are emerging rapidly. Last weeks US approval of the SapienTM valve is the most recent example." Anticoagulants are needed peri-procedurally to prevent clotting on the treated area and clotting in other organs such as the brain, which can result in a stroke; however, anticoagulants carry a risk of vascular and bleeding complications. Dr. Dangas said, "Advances in procedures such as PCI, valvuloplasty and TAVI may require improvements in anticoagulation to yield improved patient outcomes.". Clive Meanwell, MD, PhD, Chairman and Chief Executive Officer of The Medicines Company said, "These results validate the commitment we made to study Angiomax once our patent rights were supported. I look forward to seeing the BRAVO program move ahead with a planned study in more patients next year. With continued certainty, we will be positioned to explore the potential of Angiomax to deliver ...

Valvular heart disease (VHD), particularly aortic valve disease, is prevalent with increasing incidence. When surgery is not possible, or when risks outweigh benefits, percutaneous treatment options may offer effective alternatives. However, procedures may not always go as planned, and frail patients or those whose symptoms are caused by other comorbidities may not benefit from valve intervention at all. Significant effort should be made to assess frailty, comorbidities and patient goals prior to intervention. Palliative care (PC) should play a critical role in the care of patients with severe valve disease. PC is specialised medical care that aims to optimise health-related quality of life by managing symptoms and clarifying patient values and goals of care. It should be implemented at the time of diagnosis and continue throughout the disease course. Because of the paucity of studies dedicated to the provision of PC to patients with advanced VHD, further research is needed. ...

Surgical valvotomy was once the procedure of choice for critical PS; however, balloon pulmonary valvuloplasty (BPV) has now become the standard treatment. Although the procedure is usually simple, crossing the pulmonary valve from the femoral vein can be difficult, especially when severe tricuspid regurgitation and right atrium dilatation are present. In such patients, the maneuver can be simplified by using the right internal jugular vein approach. However, many ...
article{aaaf1de4-de34-469a-ad34-52c691970e90, abstract = {BACKGROUND: Treating pulmonary valve stenosis with balloon valvuloplasty (BV) is a good model to study the effect of right ventricular (RV) pressures on coronary flow. METHODS: Transthoracic Doppler echocardiography was used to register coronary flow in 10 age-matched healthy controls and 7 neonates before and 1 day after BV. RESULTS: Left ventricular fractional shortening and cardiac output increased significantly after BV. Right coronary artery diameter decreased from 1.2 +/- 0.2 to 1.1 +/- 0.1 mm (P < .02). Posterior descending coronary artery flow parameters decreased significantly, with blood flow decreasing from 8.4 to 5.7 +/- 1.9 mL/s (P < .003). RV end-diastolic pressure and RV systolic pressure explained almost totally the variation in coronary flow (r(2) = 0.87). CONCLUSIONS: RV end-diastolic pressure and RV systolic pressure determined coronary flow in neonates with critical pulmonary valve stenosis. Cardiac output and ...
Peak left ventricular pressure during balloon inflation was measured in 20 patients who underwent balloon valvuloplasty for severe aortic stenosis to define the determinants of ventricular pressure development in response to increased loading conditions. The peak left ventricular pressure ranged from 150 ± 5 to 386 ± 22 mm Hg (mean ± Sl), was reproducible in each patient with each balloon inflation (mean coefficient of variation 7.8%) and correlated with concurrent echocardiographic measurements of ejection fraction (r = 0.89, p = 0.0001) and mass/volume ratio in systole (r = 0.91, p = 0.0001) or diastole (r = 0.88, p = 0.0001). Thirteen patients with class II or more severe congestive heart failure had lower values for peak left ventricular pressure than did those without failure (225 ± 46 versus 305 ± 45 mm Hg, p = 0.002), whereas no difference in rest left ventricular systolic pressure was seen between the two groups. The measurement of peak left ventricular pressure was inversely ...
This study evaluated the mechanism of valvular area expansion during single- and double-balloon valvuloplasty in fibrotic and calcific mitral valves. Special interest was focused on the morphological features of the valves treated. Mitral valves that appeared unsuitable for commissurotomy were excised in toto at the time of mitral valve replacement in 15 patients. The excised valves were mounted in a fluid-filled chamber with a window for photographic evaluation. The chamber was perfused continuously to ensure maximal valvular opening. The valve was photographed, and the orifice area was measured before and after balloon expansion. In addition, the specimens were examined macroscopically and radiographically with regard to calcium content and degree and localization of fibrosis. These data were correlated with splitting of commissures and with rupture of leaflets. Nine valves were fibrotic, and six were calcific. Dilatation was performed first with a single-balloon catheter (diameter, 2 cm) and ...

After the procedure, you may be taken to the recovery room for observation or returned to your hospital room. You will remain flat in bed for several hours after the procedure. A nurse will monitor your vital signs, the insertion site, and circulation and sensation in the affected leg or arm.. You should immediately inform your nurse if you feel any chest pain or tightness, or any other pain, as well as any feelings of warmth, bleeding, or pain at the insertion site in your leg or arm.. Bedrest may vary from two to six hours depending on your specific condition. If your doctor placed a closure device, your bedrest may be of shorter duration.. In some cases, the sheath or introducer may be left in the insertion site. If so, the period of bedrest will be prolonged until the sheath is removed. After the sheath is removed, you may be given a light meal.. You may be given pain medication for pain or discomfort related to the insertion site or having to lie flat and still for a prolonged ...
Routine predeployment balloon aortic valvuloplasty (BAV) has historically been considered an essential part of the transcatheter aortic valve replacement (TAVR) procedure, ensuring unimpeded delivery of the prosthetic valve across the stenotic aortic valve, optimal valve expansion, and hemodynamic stability during valve deployment. This was particularly pertinent for first‐generation valves with very large profiles (22‐F and 24‐F Edwards Sapien valve [Edwards Lifesciences, Irvine, CA]1 and 24‐F Medtronic CoreValve [Medtronic, Dublin, Ireland]2), for which valve crossing was often challenging. However, its continued role as a routine adjunct given more advanced delivery systems with lower profiles (14‐F to 16‐F for the Edwards S3 and Medtronic Evolut R valves) and improved trackability remains uncertain. Routine predeployment BAV for every TAVR might not be necessary, especially as operators strive to minimize TAVR‐related risks. A tailored approach to predeployment BAV for specific ...
New conduction defects develop in as many as one-third of patients undergoing surgical replacement of the aortic valve, with LBBB being the most common abnormality (18-20). After TAVI, new conduction defects have been described in an even significantly higher number of patients, with new LBBB being the predominant new conduction defect (7-11,21-24). The anatomic neighborhood of the aortic valve to the atrioventricular bundle; degeneration of the conduction system; trauma by guidewires, catheters, and pre-implantation balloon valvuloplasty; and direct constant pressure of the implanted valve on the left bundle branch at the base of the interleaflet triangle between the right and noncoronary triangle are the potential causes (25). The frequency of new LBBB has been reported to be higher after implantation of the CoreValve prosthesis as compared with the Edwards SAPIEN prosthesis (24). This has been explained by the larger size of the CoreValve prosthesis and, in particular, the greater depth of ...

To analyze our experience with percutaneous aortic balloon valvuloplasty in newborn infants with aortic stenosis, emphasizing the extraordinary importance of myocardial perfusion. Over a 10-year-period, 21 neonates underwent percutaneous aortic balloon valvuloplasty. Age ranged from 2 to 27 days, weight ranged from 2.2 to 4.1 kg and 19 were males. All patients presented with congestive heart failure that could not be treated clinically. The onset of symptoms in the first week of life occurred in 9 patients considered as having critical aortic stenosis. Severe aortic stenosis occurred in 12 patients with the onset of symptoms in the second week of life. Mortality reached 100% in the patients with critical aortic stenosis. The procedure was considered effective in the 12 patients with severe aortic stenosis. Vascular complications included the loss of pulse in 12 patients and rupture of the femoral artery in 2 patients. Cardiac complications included acute aortic regurgitation in 2 patients and ...

Doppler peak pulmonary gradient before PBV and at one year and long-term follow-up was 91 ± 33 (range 36-200), 28 ± 12 (p,0.0001) and 26±11 mm Hg (p = 0.2), respectively. New mild pulmonary regurgitation was noted in 24 patients (28%) after PBV. Significant tricuspid regurgitation in seven patients either regressed or disappeared after PBV. ...
Background: We aimed to characterize progression of aortic stenosis (AS) with end stage renal disease (ESRD), and to determine metabolic and hemodynamic factors attributing to AS progression.. Method:A total of 73 ESRD (50 males, age 72±11 years) on dialysis with mild (n=56) to moderate AS (n=17) were enrolled. Age, sex and AS severity matched control group with eGFR above 60 mL/min/1.73m2 was selected (n=79). Transthoracic echocardiography was performed at baseline and during follow up (48±23 months). Severity of AS was accessed by aortic valve area (AVA) calculated by continuity equations. Acceleration of AS was assessed by annual AVA reduction rate. Accelerated group in ESRD patients was defined as those with the highest quartile of AVA reduction rate. Clinical outcomes included aortic valve intervention, hospital admission due to heart failure, and death.. Results: Annual AVA reduction rate was significantly higher in ESRD compared to control group (0.36±1.9 vs. 0.05±0.14 cm2/yr, ...
Pulmonary Stenosis, signs and Symptoms of Pulmonary Valve Stenosis, Examinations for Pulmonary Valve Stenosis, Treatment for Pulmonary Valve Stenosis
Stretching the stenosed valve. This is a procedure that does not involve open heart surgery. It is called percutaneous balloon commissurotomy or balloon valvuloplasty. (It is called a commissurotomy, as the area where the valve flaps (cusps) come into contact with each other are known as the commissures.) This is possible in many cases. It is done by inserting a thin tube called a catheter through the skin (percutaneous) into the main blood vessel in the top of the leg. The catheter is passed up to the heart. The tip of the catheter is placed in the mitral valve opening. A balloon at the tip of the catheter is then inflated to stretch the narrowed valve. This is often successful in widening the narrowed valve ...

A. The exact type and extent of treatment your pet may receive depends on what their diagnosis is. In fact, not every dog or cat that is diagnosed with heart disease needs treatment. However, there are many pets with heart conditions that need treatments. The treatment each pet receives is tailored to their specific needs. For instance, there are many medications that can be given, both in the emergency setting and chronically, that will help dogs and cats with congestive heart failure. While one patient may need one or two medications to improve his quality of life and help him live a longer life, another animal with a similar condition may require six or seven medications to achieve the same goal. Even still, there are other animals that are affected by conditions that do not typically respond well to medications, but can be dramatically improved by surgical procedures such as transvenous pacemaker implantation, patent ductus arteriosus coil occlusion and balloon valvuloplasty.. ...
The Twilight Time Blu-ray of Anastasia looks great. Its also a welcome relief, for the new HD transfer does not have the cold bluish-teal cast imposed over several classic Fox releases of the last few years, notably a Desk Set Blu-ray, and a King and I edition that could have been re-titled "Rhapsody in Blue". This new image is not the same scan as streams from the web: its sharper and more detailed and the colors are dark and rich. The optical transitions have only a slightly higher granularity. The cinematography flatters the excellent costumes, which are perhaps better than what would have been created for Ingrid Bergman back in Hollywood. I did notice quite a few shots with the CinemaScope mumps, as well as some with heavily distorted fields - people at the right of the screen are often half as wide as they should be.. The multi-track audio is fine as well, and Twilight Time gives us its Isolated Score Track option for fans that want to sample Alfred Newmans lush, Romanoff-flavored music. ...
An improved method for continuously determining the orientation of a movingser platform at a selected time fix. A Global Positioning System (GPS) is used to carry out the method and is made up of a plurality of twenty-four (24) earth-orbiting satellites wherein each satellite continuously transmits a pair of distinctively encoded RF signals. The GPS system is also provided with a computerized GPS receiver apparatus for use on a moving platform. The receiver apparatus is generally comprised of a rotatable antenna, a single channel multi-track geodetic receiver, a receiver microprocessor, and an orientation computer with a display. The receiver processor selects an optimum group of four satellites to be tracked. The orientation computer during antenna rotation selects a series of four equidistant points about the antenna periphery for receiving signals from each tracked satellite. The signals are transformed by the computer so as to provide a graphic data display output in near real time of the biased
Treatment of Pulmonary valve stenosis is a narrowing of the pulmonary valve, the flap that separates the lower right chamber (right ventricle) of your heart from the pulmonary artery. During circulation, oxygen-poor blood returning from your body is pumped from your heart, through the pulmonary valve and into the pulmonary artery, which carries the blood to your lungs to pick up oxygen and drop off carbon dioxide. If the pulmonary valve is constricted (stenosed), your heart has to pump harder to push blood through the valve and into the pulmonary artery, The disorder is usually present since birth (congenital). Its one of the more common heart birth defects, with the majority of the cases being mild. Pulmonary valve stenosis occurs in about one of 10 children, and females are slightly more likely to be affected than males. Adults occasionally have pulmonary valve stenosis as a complication of another illness, Pulmonary valve stenosis ranges from mild and without symptoms to severe and debilitating.

There are different options to enlarge the aortic valve annulus to allow placement of a larger prosthesis than the initial annulus size would permit. Each option is associated with unique risks and difficulties. In addition, several valve types and implantation techniques can also help with the issue of small aortic valve annulus. Nonetheless, in this case, its not clear is the high gradient is related to the fact that the valve that was placed initially was the "wrong" size or if there was another mechanism of its obstruction. Redo surgery and exposure to another prolonged bypass for a more complex procedure likely contributed to coaguloplathy. However, that can be due to the fact that the surgeon was forced to do the more complex procedure after he failed the initial, more conservative, procedure. In other words, the patient might have had risk factors that would have made the root replacement too risky and therefore it was reasonable to do the more simple procedure first. So, you cant ...

For her senior thesis, economics major and Honors Fellow Celia Rose Eddy 13 examined the effects of year-round schooling on student achievement.. Eddy did her research in Wake County, which has the largest school system in North Carolina. Wake County Schools enacted a policy in 2008 that changed dozens of primary schools to a multi-track, year-round calendar in response to budget cuts and an increasing student population.. Over the course of three semesters, Eddy worked with her mentor, Assistant Professor of Economics Katy Rouse, who had previously studied year-round schooling in Wake County. Eddy built upon Rouses research, which looked at the differences in achievement between traditional and year-round student populations.. "I was able to add a time-dependent variable that Dr. Rouse had been unable to examine due to her studys limited number of years of data available," Eddy says.. Eddy developed and disseminated surveys, compiled a dataset from multiple publicly available sources and ...

Pulmonary valve stenosis (PVS) is a heart valve disorder in which outflow of blood from the right ventricle of the heart is obstructed at the level of the pulmonic valve. This type of pulmonic stenosis results in the reduction of flow of blood to the lungs. Valvular pulmonic stenosis accounts for 80% of right ventricular outflow tract obstruction. While the most common cause of pulmonary valve stenosis is congenital heart disease, it may also be due to a malignant carcinoid tumor. Both stenosis of the pulmonary artery and pulmonary valve stenosis are forms of pulmonic stenosis (nonvalvular and valvular, respectively). PVS was the key finding that led Jacqueline Noonan to identify the syndrome now called Noonan syndrome. Play media Among some of the symptoms consistent with pulmonary valve stenosis are the following: Heart murmur Cyanosis Dyspnea Dizziness Upper thorax pain Developmental disorders In regards to the cause of pulmonary valve stenosis a very high percentage are congenital, the right ...

Contraindications (Who should not use): ...
Previously, the alternative to surgical AVR in patients deemed too "high risk" for surgery was balloon aortic valvuloplasty (BAV). Introduced in the mid-1980s, BAV as a therapy has been limited by high rates of both early and late restenosis (3, 4). BAV is a procedure in which the stenosed aortic valve is crossed with a straight wire in a retrograde fashion, and then exchanged for a stiff 0.035" guidewire upon which a 20- to 23-mm diameter balloon catheter is tracked up across the aortic valve. With the initiation of rapid pacing of the right ventricle, balloon inflation across the stenosed aortic valve is performed. In addition to high rates of restenosis, the procedural risks of BAV include embolic stroke, vascular complications, and severe aortic insufficiency. Currently the ACC/AHA guidelines limit the use of BAV to either cases of palliation or situations "to bridge" unstable patients to a more definitive therapy, such as AVR (5 ...

Parachute mitral valve (PMV) is a congenital heart anomaly which consists of a unifocal attachment of the mitral valve chordae into a single or dominant papillary muscle. This morphological anomaly determines the impairment of mitral leaflet motion, resulting in different grades of mitral stenosis. Due to its frequent association with other congenital cardiac defects requiring surgical correction, the therapy of a relevant stenotic PMV is usually represented by surgical commissurotomy. Herein is reported the case of a PMV treated by surgery in infancy, which showed a severe restenosis after 34 years and was successfully treated by percutaneous valvuloplasty with the additional creation of a restrictive atrial communication ...

Minimally invasive cardiac procedures (sometimes called interventional procedures) are a category of treatments for certain heart conditions that allow the veterinary cardiologist to treat or correct the problem without invasive heart surgery. These procedures include, balloon valvuloplasty, pacemaker implantation, catheter occlusions, and catheter ablation. They are performed in a cardiac cath lab. Fluoroscopy (video X-rays) and echocardiography (ultrasound of the heart) provide imaging to help guide the procedure in the cath lab.. The animals are placed under anesthesia and are closely monitored. A catheter is placed into a vein or artery in either the groin or the neck providing access to the vessel. Then a thin guide wire is passed through the catheter into the vessel and is advanced under image guidance to the area of interest in or near the heart. In most types of minimally invasive cardiac procedures, a long catheter is then passed over the guide wire. Contrast solution is injected ...

The main finding of this single-center observational study is the high rate of VARC-2-defined device success (97.6%) and freedom of the composite VARC-2-defined early safety endpoint at 30 days of 90.0% with an all-cause mortality rate of ,1%. The VARC-2-defined composite endpoint early safety at 30 days summarizes important measures of complications and mortality and has been proposed for assessment of patient safety in TAVR. Two recent meta-analyses have reported freedom from VARC-2-defined early safety composite endpoint at 30 days in ∼77% of the cases (17,18). Compared with these data, in the present intermediate-risk population, we observed freedom of this composite endpoint in 90% after 30 days, indicating an excellent safety profile of this novel device.. Device success is a composite endpoint especially driven by the presence of residual moderate or severe paravalvular leakage, showing an incidence of 12% to 24% in the literature (19). As emerging evidence indicates a strong influence ...
David H. Adams, MD, national co-principal investigator for the CoreValve U.S. Pivotal Trial, presented study results showing minimally invasive transcatheter aortic valve replacement (TAVR) with the CoreValve System is superior to surgical aortic valve replacement (SAVR) at one year in patients with severe aortic stenosis who are considered high risk for surgery.. Dr. Adams presented the findings at a late-breaking clinical trial session at the 63rd Annual Scientific Session of the American College of Cardiology (ACC), and also published simultaneously in the New England Journal of Medicine (NEJM).. The CoreValve High Risk Study is the first prospective, randomized study to show any transcatheter aortic valve to be superior to surgery. The CoreValve System was approved by the U.S. Food and Drug Administration (FDA) in January 2014 for patients considered extreme risk for surgery; the device is not currently approved in the U.S. for use with patients at high risk.. The head-to-head study met its ...
The pulmonary valve is one of the valves that allow blood from the body to return to the lung for oxygenation. The Department of Cardiology at National Heart Centre Singapore shares more.
Another treatment option that is less invasive than valve repair or replacement surgery is balloon valvuloplasty. This is a non-surgical procedure in which a special catheter (hollow tube) is threaded into a blood vessel in the groin and guided into the heart. At the tip of the catheter is a deflated balloon that is inserted into the narrowed heart valve. Once in place, the balloon is inflated to stretch the valve open, and then removed. This procedure is sometimes used to treat pulmonary stenosis and, in some cases, aortic stenosis. ...

Methods and Results-Data were obtained using the national inpatient sample between the years 2011 and 2014. We used the International Classification of Diseases, Ninth Edition, Clinical Modification procedure codes 350.5 and 350.6 to identify patients undergoing transcatheter aortic valve replacement. Primary outcome of interest was in-hospital mortality. A 2-tailed P value ,0.01 was considered to denote statistical significance for all analyses. We identified 42 189 patients who underwent transcatheter aortic valve replacement between the years 2011 and 2014. Of these, 62.1% (n=26 229) had no CKD/ESRD, 33.7% (n=14 252) had CKD, and 4% (n=1708) had ESRD. Patients with CKD or ESRD had greater in-hospital mortality, hospital length of stay, hemorrhage requiring transfusion, and permanent pacemaker implantation (P,0.001). ...
Patients who are suffering with severe aortic stenosis, which is the narrowing of the hearts aortic valve opening that restricts blood flow, have a minimally invasive surgical option available at the Heart and Vascular Center at Manatee Memorial Hospital. Transcatheter Aortic Valve Replacement (TAVR) is an advanced heart valve replacement procedure that offers new hope to patients who have aortic valve stenosis and are at high or extreme risk for open-heart surgery. TAVR patient Eugene Vaadi describes his experience:
Repair of the Transcatheter aortic valve is a minimally invasive procedure. This technique is used without removing it to treat or restore old and damaged aortic valve. The technique used to insert a new valve to the place of the old aortic valve is called the Transcatheter aortic valve replacement system. Between the left atrium and the left ventricle is the mitral valve. Mitral valve disorder is a condition in which the valve ceases working properly, leading to abnormal blood flow. This abnormal blood flow can lead to diseases such as prolapse of the mitral valve and regurgitation of the mitral valve.. Renub Research latest study report "Transcatheter Heart Valve Replacement Market, Volume, Share by Materials (Mechanical and Tissue) Position (Transcather Mitral Valve Replacement and Transcatheter Aortic Valve Replacement), Region (United States, Germany, China, France, Italy, Japan, Spain, United Kingdom, India and Brazil), Company Analysis" provides a detailed and comprehensive insight of the ...
