C ALCIFIC STENOSIS of the aortic valve is a well-recognized and relatively common clinical and pathological entity. In contrast, calcific pulmonic stenosis is rarely encountered either at operation or necropsy. We have observed small deposits of calcium in one or more pulmonic valve cusps in patients who lived into adulthood with left-toright intracardiac shunts, and in older persons with sever...

Fourteen infants, all under 6 months of age, underwent surgery for the relief of severe valvar pulmonary stenosis. A modified Brock (transinfundibular valvotomy) procedure was performed in all cases. Dilatation of the pulmonary valve with a mosquito clamp and biliary dilator is the basis of the modified operation. All infants survived the operation. In two patients there is residual, significan...

The abnormalities of pulmonary arterial blood supply in mitral stenosis, consisting primarily of constriction of lower lobe vessels with resultant upper lobe preferential flow, was assessed by means of pulmonary angiography in 30 patients with mitral stenosis uncomplicated by other cardiac diseases. The abnormalities in blood flow correlated best with both the pulmonay artery pressure and the p...

INTRODUCTION Pulmonary stenosis remains the most frequent complication and cause of reintervention after the arterial switch operation for transposition of the great arteries We investigated the onset, incidence, and outcome of pulmonary stenosis after arterial switch operation in neonates with transposition of the great arteries and intact ventricular septum. METHODS Arterial switch operatio...

The aims of this study were to reveal the prevalence of complications associated with PBV over a long-term follow-up, and to investigate the factors related to those complications, especially pulmonary restenosis. Forty dogs who underwent PBV were retrospectively reviewed. Long-term follow-up was available in 22 dogs. Exacerbation of PI and TR after PBV was observed in some dogs; however, right...

BACKGROUND Mitral valve stenosis is often associated with increased pulmonary vascular resistance resulting in pulmonary hypertension, which may lead to or exacerbate right heart dysfunction. Hypocapnia is a known pulmonary vasodilator. The purpose of this study was to evaluate whether induced hypocapnia is an effective treatment for pulmonary hypertension following elective mitral valve replac...

OBJECTIVES This study sought to determine the results of a novel transcatheter management approach in tetralogy of Fallot with diminutive pulmonary arteries. BACKGROUND Tetralogy of Fallot with diminutive pulmonary arteries and severe pulmonary stenosis is rare and resembles tetralogy of Fallot with pulmonary atresia: There is a high incidence of aortopulmonary collateral channels, arborizati...

Mitral stenosis is associated with increased pulmonary artery pressure and resistance. Adrenomedullin, discovered in human pheochromocytoma tissue in 1993, has shown to dilate the pulmonary vessels and so may participate in the control of pulmonary circulation. In this study, we assessed the plasma concentration of adrenomedullin in patients complaining of rheumatic mitral stenosis, with and wi...

cardiac hydatid cyst (chc) is a rare disease that was endemic in some regions especially in sheep-raising areas. the most commonly accepted theory for the routes of heart involvement in hydatid cyst was infestation by the hexacanthus embryo through coronary arteries. here, we describe a case with the primitive cardiac hydatid cyst located around the pulmonary valve (pv) and main pulmonary arter...

UNLABELLED Percutaneous balloon aortic valvuloplasty (BAV) was a rare procedure in catheterization laboratories because of its limited prognostic impact. The recent advent of transcatheter aortic valve implantation (TAVI) has led to a resurgence of BAV, opening the way to a new indication as a bridge to TAVI. Herein, we reported an 83-year-old man with critical aortic valve stenosis and pulmona...
