Eighty patients with tight and pliable mitral stenosis were randomized in a prospective trial comparing percutaneous balloon valvuloplasty and open commissurotomy. Mitral valve area increased significantly in both groups immediately after the procedures. However, a decrease in mitral valve area occurred in both groups at 6, 12 and 24 months during the follow-up. There was no death in either group. Two patients had significant mitral regurgitation after percutaneous balloon valvuloplasty. After 24 months, all patients in the commissurotomy group and 97.4% of the patients in the balloon valvuloplasty group were in New York Heart Association functional class I or II.
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 ...
Percutaneous balloon dilatation was attempted in 15 consecutive neonates (mean age 7.3 (range 1-27) days and weight 3.2 (range 2.5-4.1) kg) with critical stenosis of the pulmonary valve. Dilatation was successful in 11 (73%) patients. The mean balloon to annulus ratio was 1.1 (range 0.6-1.77). The ratio of right ventricle to femoral artery systolic pressure decreased from a mean (1 SD) of 1.4 (0.32) before to 0.8 (0.24) after dilatation and the transvalvar gradient decreased from 81 (29.7) mm Hg before to 33 (27.7) mm Hg after dilatation. All four (27%) patients in whom dilatation was unsuccessful underwent surgical valvotomy. Complications of balloon dilatation occurred in three (20%) patients; these included retroperitoneal haematoma (one) and iliofemoral venous occlusion (two). In one (7%) patient severe hypoxia and hypotension developed when the valve was crossed with a guide wire and balloon catheter. Despite successful dilatation he died 7 days after the procedure. During a mean (1 SD) ...

Why is the doctor performing this procedure?. To open up a coronary (heart) artery that is narrowed or blocked by plaque build-up (atherosclerosis), and to structurally support that opening by permanently placing a metal stent within the artery.. What is the procedure?. A stent is a mesh-like wire cylinder. Stent placement is often part of a PTCA (angioplasty) procedure. As in angioplasty, a catheter is inserted into an artery-usually in the groin-but sometimes in the arm or wrist. The catheter is advanced to the heart, and a series of x-ray pictures (coronary angiogram) are taken to clearly visualize the heart artery that is narrowed. Then a balloon-tipped catheter is advanced to the heart, and into the narrowed coronary artery. Inside the artery, the balloon is inflated and deflated several times, compressing the plaque against the artery wall and widening the artery so blood flow improves. This balloon-tipped catheter is removed, and a separate balloon-tipped catheter, with a stent attached, ...

But, if you recall, I stated many years ago that randomized trials were premature because there was no standard accepted best practice of the procedure, a necessary consition in which to judge the treatment. As in his early papers, the treatment was inadequate. The high restenosis rate in those early papers indicated that technical modifications were necessary. In this new study, they used compliant low pressure balloons to start and then only went to they thought that was necessary. They did not use IVUS and thus were guessing on balloon size since venography is inaccurate in estimating balloon size. They rarely used high pressure balloons and, when they did, they used balloon sizes that I am quite confident did not expand the lesions to effect ively break the stenosis. Although Zamboni alluded to the effects of the surrounding venous structures such as the dural sinuses, the renal vein and the iliac vein, these were not studied and their role in venous congestion should not be overlooked.

Imagine a broad piece of brittle wax, lubricated, obscured at its bottom (as it were) end by tender tissues; slippery by its nature, ungraspable by its geometry. I sat between the mans legs for a goodly amount of time, trying everything of which I could think: big tongs chipped off pieces of wax and the candle squirted headward. I slid a balloon-tipped catheter along side and as high as I could wriggle it, inflated the balloon and withdrew without success. I heated a round-tipped probe thinking I could melt it in, let things cool, and pull it out. Because the north end of the candle was well above the mans ribs, I couldnt apply counter pressure to squeeze it downward. I could stretch his sphincter enough to insert most of my fingers, but the sheer size of a hand grasping a three-inch wide waxy thing and sliding back out was impossible.

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 ...
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.

Background-Long-term follow-up after percutaneous mitral commissurotomy (PMC) enables predictive factors of late results to be identified. Methods and Results-Late results of PMC were assessed in 1024 consecutive patients. Good immediate results, defined as valve area ≥1.5cm2 without mitral regurgitation ,2/4, were obtained in 912 patients (89%). These 912 patients were randomly split into 2 cohorts comprising 609 and 303 patients, used respectively to develop and validate a scoring system predicting late functional results. The 20-year rate of good functional results (survival without cardiovascular death, mitral surgery or repeat-PMC, and in NYHA class I or II) was 30.2±2.0%. A multivariable Cox model identified 7 predictive factors of poor late functional results: higher final mean gradient (p,0.0001), interaction between age and final mitral valve area (p,0.0001), showing that the impact of valve area decreases with age, interaction between sex and valve calcification (p,0.0001) showing ...
TY - JOUR. T1 - Cannulation in the diseased aorta. T2 - A safe approach using the Seldinger technique. AU - Khoynezhad, Ali. AU - Plestis, Konstadinos A.. PY - 2006/11/9. Y1 - 2006/11/9. N2 - The Seldinger technique is a method of femoral cannulation that has been used to establish cardiopulmonary bypass. Reports of cannulation of the ascending aorta for antegrade perfusion using the Seldinger method are anecdotal. To the best of our knowledge, the approach described herein for direct cannulation of the ascending aorta with use of the Seldinger technique for antegrade perfusion has not been previously described in the English-language medical literature. This method is helpful when the surgeon is treating a patient who has a calcified ascending aorta, complicated aortic dissection, calcified femoral vessels, or a diseased thoracoabdominal aorta. In such cases, retrograde perfusion has been associated with severe complications as a result of atheromatous embolization from the descending thoracic ...

A randomized controlled double blinded study to investigate whether a specially designed double balloon catheter is more efficient than a foley catheter for cervical ripening and induction of birth.. 160 women with singleton term pregnancies with un ripe cervix and no contraindications for catheters will be included and randomized to either double og single balloon catheters for cervical ripening. Efficacy wil be assessed at removal of the catheter, measured by the amount of women where the cervix has become ripe enough for amniotomy.. Our hypothesis is that double balloon catheters will give a greater amount of women where amniotomy upon catheter removal is possible. Secondary outcomes as time from induction till birth, vaginal deliveries and complications during or after birth for the mother or child will also become recorded. ...

Endotracheal suctioning is an important supportive treatment for patients requiring mechanical ventilation. Traditionally, in line suction catheters are changed every 24 hours to prevent the development of VAP. A paucity of research exists on the use of in line suction catheters and the optimal time for change. The study by Kollef et al is one of very few that attempts to evaluate a closed multiple use suction catheter system for outcomes of safety and cost.. The study was limited to 1 North American hospital. Results may have differed if other populations had been included in the study. Strengths of the study included the random allocation of eligible patients to groups and the attempt to keep caregivers blinded by doing scheduled in line suction changes during evening or night shifts. The diagnosis of VAP was acknowledged as a potential limitation of the study because it was based on clinical criteria and did not include quantitative cultures of lower respiratory tract secretions which would ...
Single balloon enteroscopy (SBE) procedure is a procedure for diagnosis and treatment in patients with abnormality of gastrointestinal tract especially for small bowel. It commonly performed either anterograde or retrograde intubation. The aim of the study is to compare and evaluate the success rate of propofol-balanced anaesthesia (PBA) for the SBE procedure between antegrade and retrograde intubation. The primary outcome variable of the study was the successful completion of the procedure. Failed procedure is defined as the procedure can not be completed by using PBS technique or sedation-related serious adverse events such as severe hypoxaemia (SpO2 |85% more than 3 min and can not relief by airway management), severe cardiorespiratory instability, are occurred. The secondary outcome variables were sedation-related complications, mortality rate and haemodynamic parameters.

Successful vascular access (VA) cannulation is integral to the delivery of adequate dialysis, highlighting the importance of ensuring the viability of arteriovenous access in hemodialysis (HD) patients. Missed VA cannulation can lead to infection, infiltration, hematoma or aneurysm formation resulting in the need for access revision, central venous catheter (CVC) placement, or permanent loss of VA. Cannulation-related complications can also negatively impact on a patients dialysis experience and quality of life. This study aimed to identify patient, VA and nurse factors associated with unsuccessful VA cannulations. A prospective cohort study was conducted in HD patients with a permanent VA from three HD units. Data on patient, VA and nurse characteristics, plus, cannulation technique were collected for each episode of cannulation. General Estimating Equation was used to fit a repeated measures logistic regression to determine the odds of cannulation success. We collected data on 1946 episodes of

Intratracheal aspiration in a patient on ventilation is generally performed using a catheter. Of late, closed suction systems have been used more frequently than open systems. To remove tracheal secretions through the intratracheal tube, catheter suction is used, and the suction catheter may be of the closed- or open-type. The catheters are cleaned by flushing with sterile 0.9% saline, resulting in dropping of dew. This phenomenon is caused by some factors: influence of flow, clogging of the suction tube, problem of manipulation of flushing and angle between the intubation tube and the connection port. But this dropping has not yet been investigated. In this study, we focused at this angle and we used the test lung which is simulated machine on behalf of patient. We consider two situations adult and child, also two types of catheters Eco-Cath and Ty-care. In child case we consider elbow-type suction catheters and Y-connector type. The angle was set at 0°, 20°, 40°, 60°, and 90°, and we observed the
Although the 5-F catheter is reputed to cause less vascular trauma than larger catheters, subintimal injections of contrast material have occurred following intimal damage by the catheter tip. Microscopic studies of the tips of two widely used 5-F polyethylene catheters have revealed a difference in configuration resulting in one of the catheters becoming markedly damaged during angiography. The authors make recommendations for finishing and protecting the catheter tip. ...

Balloon valvuplasty also called balloon valvutomy is an alternative management to valve replacement procedure. It is a less invasive procedure that opens or dilates a stenosed (narrowed) valve of the heart due to a congenital defect, rheumatic fever, calcification and aging. It uses a balloon-tipped catheter to dilate a narrowed area.. There are four valves in the heart namely: tricuspid, pulmonic, mitral and aortic valves. These valves are essential for efficient blood flow in the heart. In some cases, a valve narrows causing an obstruction to blood flow. Balloon valvuplasty is used in the treatment of these cardiac disorders that blocks the blood flow.. The procedure is done through a cardiac catheterization with an x-ray machine that has a special TV monitor or screen. Then a needle is inserted into the blood vessel and a contrast medium is injected. The dye is used to pinpoint the exact location of the blocked area as viewed on the screen. Once the narrowed valve has been identified, a thin ...
Idiopathic achalasia is a primary esophageal motor disorder characterized by esophageal aperistalsis and abnormal lower esophageal sphincter (LES) relaxation in response to deglutition. It is a rare disease with an annual incidence of approximately 1/100,000 and a prevalence rate of 1/10,000. The disease can occur at any age, with a similar rate in men and women, but is usually diagnosed between 25 and 60 years. It is characterized predominantly by dysphagia to solids and liquids, bland regurgitation, and chest pain. Weight loss (usually between 5 to 10 kg) is present in most but not in all patients. Heartburn occurs in 27%-42% of achalasia patients. Etiology is unknown. Some familial cases have been reported, but the rarity of familial occurrence does not support the hypothesis that genetic inheritance is a significant etiologic factor. Association of achalasia with viral infections and auto-antibodies against myenteric plexus has been reported, but the causal relationship remains unclear. The

Using ultrasound guidance, access was obtained into bilateral common femoral arteries and 7 Fr 23 cm sheaths were placed. On the left side, a guidewire was advanced and the distal under-expanded stent was treated with a 7 x 20 mm balloon, and subsequently, a 8 x 20 mm balloon at rated burst pressures. The stented segment showed no appreciable luminal gain. The balloon catheter was then removed.. Due to the concern for a similar suboptimal angiographic result for the newer more proximal lesion using the same balloon and stent strategy, the decision was made to modify the calcified plaque using orbital atherectomy prior to stent placement.. The guidewire was exchanged for a ViperWire Advance® guide wire in the left iliac artery. A peripheral Diamondback® 2.00 mm Solid Crown was used to perform atherectomy with one pass on medium and four passes on high speed. This was followed by post-dilation with an 8 x 20 mm balloon with full expansion. Kissing balloon angioplasty of bilateral proximal common ...
Major factors driving the femoral cannula market include increase in number of patients suffering from chronic conditions such as hypertension, cardio vascular disorders, and other hematological disorders; rise in demand for new and minimally invasive techniques for hemodynamic access from patients and healthcare providers; introduction of new and advanced femoral cannulae with distinct features by major and domestic market players; and distinct advantages of femoral cannulation over other peripheral catheterization techniques. Numerous clinical studies about new application areas of femoral cannula are being conducted around the world. This is expected to open up new applications and alternatives for the use of femoral cannulation technique. Increase in number of hospital emergency admissions due to trauma and rise in patient population requiring hemodialysis are some of the factors estimated to propel the global femoral cannula market during the forecast period.. The global femoral cannula ...

A ureteric balloon catheter is a balloon catheter intended for treating strictures of the ureter. In fact it is a double J stent on which a balloon is mounted. It is connected to a delivery device (pusher) to introduce it from the bladder into the ureter. The system comprises a non-return valve device, and a pusher with a stylet and two ports. The sideport is for injecting contrast agent to inflate the balloon, while the straight port is for the guidewire. The catheter has a relatively large-diameter central lumen and a shaft of 2 mm (6 Fr.). The balloon is in two sections: a long narrow section or shaft and a larger cranial bulb. The larger cranial bulb prevents distal migration, while the longer narrow section maintains the increased diameter of a predilated stricture in the ureter section. ...

Those who manage the anesthetic care of children who need an arterial line know that insertion can be difficult. The pulse is felt, yet pass after pass fails to cannulate the artery. Ultrasound guidance is becoming more popular, particularly for difficult arterial cannulation.. Dr. Yoshinobu Nakayama, Department of Anesthesiology and Intensive Care, Kyoto Prefectural University of Medicine, Kyoto, Japan, and colleagues first determined factors that predicted ultrasound-guided percutaneous radial arterial catheterization in children and then used the strongest predictor of success as the basis of a randomized trial. Their results are presented in this months Anesthesia & Analgesia in the article A Novel Method for Ultrasound-Guided Radial Arterial Catheterization in Pediatric Patients.. The authors used the Sonosite M-Turbo® ultrasound system. The arterial catheter was a 24 gaugeJelco® Plus catheter. The authors considered 102 patients in the initial assessment phase.
