Widening of a stenosed HEART VALVE by the insertion of a balloon CATHETER into the valve and inflation of the balloon.
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.
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.
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.
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.

A valve situated at the entrance to the pulmonary trunk from the right ventricle.
The thin membrane-like muscular structure separating the right and the left upper chambers (HEART ATRIA) of a heart.
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.

Dilation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply.
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.
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.
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.
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.
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.
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.
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.

Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues using a transducer placed in the esophagus.
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).
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).
The vein accompanying the femoral artery in the same sheath; it is a continuation of the popliteal vein and becomes the external iliac vein.
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.
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.

Elements of limited time intervals, contributing to particular results or situations.
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.
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.
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.

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)

Objective: Percutaneous mitral balloon valvuloplasty (PMBV) is the method of choice in treatment of patients with hemodynamically significant mitral stenosis. We aimed to analyze acute and long-term clinical and echocardiographic consequences of PMBV. Methods: In this retrospective cohort study; 311 patients who underwent PMBV in our Cardiology Clinic at Turkiye Yuksek Ihtisas Education and Research Hospital between January 2000 and March 2004 were evaluated for acute procedural outcomes and primary endpoints (death, rePMBV, mitral valve replacement (MVR)). All 311 patients were contacted by phone call or letter at least five years after the procedure. Of the 311 patients, 87 who defined NYHA class II-IV symptoms were invited for a control visit and detailed echocardiographic evaluation. Sixty-three patients out of 87 who completed follow-up were enrolled for long-term consequences. Those 63 patients were subclassified into two groups as those without any negative event (n=26) (Group 1) and ...

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, ...

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 ...

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.. ...
The aortic valve annulus is part of the fibrous skeleton of the heart. It functions to support the valve and root of the aorta against the high pressures resulting from left ventricular systole. It consists of a ring of collagenous tissue that surrounds and supports the aortic orifice.. The annulus is arranged as three arches. The distal parts of each arch blend with the fibro-elastic tissue of the aortic sinuses. The part of each arch that faces the lumen of the aorta blends with the lamina fibrosa of the valve leaflets.. The proximal part of each arch shows a collagenous thickening at its most inferior point:. ...

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.
Women with valvular heart disease have an increased risk of adverse outcomes in pregnancy; however, with appropriate evaluation and treatment, most women can successfully bear healthy children. During pregnancy, pulmonary stenosis is generally well tolerated in the absence of other haemodynamically significant lesions. We present a case of a multiparous woman,who is pregnant with her sixth child, with a severe pulmonary stenosis. She presented with exertional chest pain and dyspnea. She was managed successfully with balloon valvuloplasty.
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.

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. ...

Objective: To evaluate the long term clinical results of percutaneous mitral balloon valvuloplasty in patients with rheumatic mitral stenosis in Colombia, South America.Background: In 1993, Colombia, South America began a National Mitral Balloon Valvuloplasty Registry. This multicenter database was designed to establish the longterm safety and efficacy of percutaneous mitral valvuloplasty, as well as rate of restenosis.Methods: Between January 1993 and December 2011, 182 patients |18 years old were treated for rheumatic mitral stenosis with percutaneous valvuloplasty in two centers in Colombia, South America. Clinical, echocardiographic and hemodynamic data were stored in an electronic database. The Inoue Balloon technique was used in 99% of patients. The longest follow-up period was 15 years.Results: 182 patients were included; women (89%), hypertension (19%), dyslipidemia (1.6%), smoking (8.8%), diabetes (5.5%) and renal failure (1%). Forty-six patients (25.7%) were NYHA functional class III-IV.

N2 - Background: Critical pulmonary stenosis (PS) is one of the life-threatening congenital heart diseases which present during the neonatal period with cyanosis. 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 ...
BIBA Research, the UK-based market research specialists for the medical technology industry, is set to present the latest findings of its Transcatheter Heart Valve (TAVI) report on April 26. The report covers the data period January-March 2010 and is part of BIBA Researchs long-established European Cardiovascular Monitor. BIBA Research said that the monitor on transcatheter heart valve was launched in coincidence with the TCT Conference in San Francisco previous year and represents the third-party investigation on market trends and penetration of transcatheter heart valve replacement and repair technologies in West Europe. The monitor tracks quarterly device consumption from a panel of over 300 hospitals in 15 countries. As per the research, Transcatheter (also known as percutaneous) heart valve implantation has one of the growth potentials in medical technology. The implantation of an aortic valve in humans was performed by Alain Cribier, French cardiologist, in 2002. Since then, transcatheter ...
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 ...
