“Balloon valvulotomy” of congenital pulmonary valve stenosis with tricuspid valve insufficiency

Abstract

The rare congenital anomaly of pulmonary valve stenosis and massive tricuspid valve insufficiency with intact ventricular septum is a lethal condition without reported survival after attempted treatment. In a neonate suffering from this syndrome, the pulmonary valve stenosis was relieved by rupturing the fused valve with a balloon catheter introduced transvenously. The desperate condition of the patient quickly improved after this procedure, with subsequent disappearance of the tricuspid valve incompetence. Balloon rupturing of fused valves at angiography may represent a therapeutic alternative in cases in which surgical valvulotomy is associated with a high mortality.

Balloon angioplasty of aortic coarctation: A review

“…None of these patients with aneurysm required therapy nor did any aneurysms rupture, although elective resection and repair was advocated by some workem60 We restudied 20 children 6-30 months following dilatation of native coarctations and 4 children, [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] months following dilatation of recoarctation and none devela* aneurysms.39 The reason for this difference is not clear. We postulated use of large balloons, inadvertent manipulation of cathetetdguidewires in the region of freshly dilated aortic coarctation, and misinterpretation or overinterpretation of aneurysm as possible causes.31 The observations of h e r et a2.…”

“…75 A quarter of a century later, Semb et al, using an inflated balloon-tipped angiographic catheter, ruptured the valve when the catheter was withdrawn from the main pulmonary artery to the right ventricle, reducing the outflow gradient. 76 However, it was the introduction of static balloon dilation by Kan and her colleagues that fostered the application of this therapeutic modality to a greater audience. 77,78 Over the past 2 decades, the technique has become the "treatment of choice" for pulmonary valve stenosis at any age and with any valve morphology.…”

Balloon pulmonary valvuloplasty: A Review

“…2 The remaining two children from Group XI1 had residual gradients of 45 and 60 mmHg on restudy, respectively, at 12 and 7 months following initial balloon valvuloplasty ; no repeat balloon valvuloplasty was performed, but these children are being followed clinically. Fourteen different variables (Table VII) were examined by multivariate logistic regression analysis to identify factors associated with restenosis.…”
