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 peripheral 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 metal cylinder. Stent placement is often part of a PTA (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 blocked peripheral artery, and a series of x-ray pictures are taken to clearly visualize the artery that is narrowed. Then a balloon-tipped catheter is advanced into the narrowed 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, is advanced to the area that was ...

A method of manufacturing a folding balloon catheter for use as an angioplasty device, wherein the balloon catheter has atherotomes (21) attached to the exterior of the balloon (12), includes inflating a balloon to its expanded state. A plurality of patches (18) of a curable elastomer adhesive are then applied at selected locations on the outside surface of the inflated balloon, and an atherotome is attached to the balloon at each of the patches. The inflated balloon, with attached atherotomes, is then partially cured to more firmly attach the atherotomes to the balloon. The balloon is then deflated to a contracted configuration in a manner which forms a plurality of flaps (54) in the balloon between the atherotomes. The deflated balloon is then cured to completion to establish a permanent set in the flaps which enable the balloon catheter to be repeatedly inflated and deflated during operation between predictable expanded and contracted configurations.

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.

BACKGROUND AND AIM OF THE STUDY: Aortic cannulation during cardiac surgery is a potential etiological factor for perioperative stroke. Cannulae may dislodge aortic-wall calcifications. In addition, the sharp edge of the cannula-tip may shear off vessel-wall tissue, which can be expelled into the lumen. This hypothesis concerning source of emboli was tested in a noncalcified aortic perfusion model.. METHODS: Pig aortas were pressurized and cannulated. Washout samples were collected before and after cannulation (n = 40). Particles were deposited onto a 10-microm filter and evaluated by microscopy and digital image analysis.. RESULTS: A higher incidence of particles generated by cannulation was noted as compared to before the maneuver (p , 0.001). This increase included small (,0.1 mm, p , 0.001) and intermediate-size particles (0.1-0.5 mm, p , 0.001). Particles above 0.5 mm were few and were not associated with cannulation.. CONCLUSIONS: Cannulation was a source of embolic material in the ...
