The valvular disease usually involves two conditions: valvular stenosis and valvular insufficiency. Valvular stenosis occurs when a valve opening is smaller than normal due to stiff or fused leaflets. The narrowed opening may make the heart work very hard to pump blood through it. This can lead to heart failure. All four valves can be stenotic (hardened, restricting blood flow); the conditions ...

Co-occurrence of atrial septal defect and pulmonary valve stenosis is a rare entity for adult population. It is possible to correct both the pulmonary stenosis and the defect in the atrial septum by transcatheter methods. We present a case of right to left shant due to severe pulmonary stenosis and atrial defect which was successfully corrected by transcatheter pulmonary valvuloplasty and closu...

FEBRUARY 2004 I ENDOVASCULAR TODAY I 31 D uring the last 2 decades, percutaneous endovascular therapies have revolutionized the treatment of coronary artery disease. However, the development and dissemination of percutaneous approaches to heart valve disease have been less rapid. Whereas rheumatic mitral stenosis and congenital aortic stenosis are effectively managed by balloon valvuloplasty in...

Pregnancy can cause life threatening complications in women with mitral stenosis, and there is a substantial risk of fetal death if valvotomy under cardiopulmonary bypass is required. A patient is described in whom pulmonary oedema developed after delivery of her first child by caesarean section 13 months previously. Subsequent cardiac catheterisation showed severe mitral stenosis (valve area 0...

A 14-year-old patient with the complex congenital heart defect of transposition of great arteries, ventricular septal defect and pulmonary stenosis, after the "réparation à l'etage ventriculaire" operation at the age of 3, was admitted to the hospital with critical pulmonary stenosis with a maximal right ventricle-pulmonary artery (RV-PA) gradient of 110 mm Hg. Transcatheter pulmonary valve imp...

INTRODUCTION AND OBJECTIVES Percutaneous pulmonary valvuloplasty is the preferred interventional procedure for pulmonary valve stenosis. The aim of this study was to evaluate the effectiveness of this technique, assess the factors leading to its success, and determine the long-term results in the pediatric population. METHODS The study included 53 patients with pulmonary valve stenosis underg...

OBSTRUCTION of a stenotic pulmonary valve by the exploring cardiac catheter, a serious and not infrequent complication of cardiac catheterization, has received little attention in the literature.1-4 Experiences in this laboratory indicate that pulmonary valve obstruction can occur both in a manifest, symptomatic form and in a concealed, asymptomatic form in patients with severe pulmonary stenos...

Valvular involvement by disease causes stenosis, insufficiency (regurgitation or incompetence), or both. Stenosis is the failure of a valve to open completely, thereby impeding forward flow. Insufficiency, in contrast, results from failure of a valve to close completely, thereby allowing reversed flow. These abnormalities can be either pure, when only stenosis or regurgitation is present, or mi...

Percutaneous mitral valvuloplasty has been proposed as a nonsurgical technique for treating high-risk patients with mitral stenosis who are deferred from mitral valve replacement. The effect of this technique on patients with pulmonary hypertension, however, has not been fully evaluated. Accordingly, serial assessment of pulmonary vascular resistance was made in 14 patients with critical mitral...
