Background: Pulmonary hypertension (PH) is common in patients with mitral valve disease. Objective: To determine the factors associated PH among disease, and similarities differences subgroups of stenosis (MS) regurgitation (MR). Materials Methods: Patients isolated moderate to severe organic disease were prospectively enrolled. was defined echocardiographically as pulmonary artery systolic pre...

OBSTRUCTION to the outflow of blood from the right ventricle may occur as a result of congenital stenosis of the pulmonary valve, of the infundibulum, or of the supravalvular area. These all result in a fixed constriction of the lumen of the involved region. Recently, considerable interest has been focused upon a more dynamic type of infundibular obstruction that occurs in a number of patients ...

A 63-yr-old patient presented with a preoperative diagnosis of aortic stenosis and pulmonary stenosis for aortic valve (AV) replacement and possible pulmonary valve (PV) repair. His symptoms included chest heaviness and shortness of breath. A preoperative transthoracic echocardiogram demonstrated calcified tri-leaflet AV with severe stenosis and a peak pulmonic flow velocity of 3.7 m/s. Cardiac...

Acquired pulmonary stenosis refers to narrowing of the right ventricular outflow tract or main pulmonary artery which has developed after birth. It may arise from external pressure or from an intrinsic pathological process, and is generally regarded as a rare condition because few cases have been reported. Our experience, however, suggests that it is probably not as rare as previously believed ...

Simple pulmonary stenosis is relatively common. Wood (1950) considers it to account for 12 per cent of cases of congenital heart disease and Campbell (1954) gives the figure of 10 per cent. The two largest series of cases to be reported are those of Abrahams and Wood (1951) 69 cases, and Campbell (1954) 100 cases. This paper deals with a consecutive series of 33 cases. The clinical features are...

Hemoptysis may occur in patients with pulmonary venous obstruction and prominent decompressing vessels in the airways adjacent to the affected pulmonary veins. The options for treatment of hemoptysis are limited, particularly when efforts to alleviate pulmonary venous obstruction have failed. Here we describe a patient with hemoptysis associated with stenosis of the central left upper pulmonary...

AMONG the congenital malformations in t& which an abnormal relationship exists between the aorta and pulmonary trunk is that in which both of these vessels arise from the right ventricle. The only outlet for the left ventricle is a ventricular septal defect. Right ventricular infundibular stenosis may or may not be associated. These cases apparently are extremely rare,1-3 and only a few have be...

SURGICAL treatment of pulmonary stenosis has advanced to the point where a choice of several operative technics is available. This study constitutes a comparative review of the late recatheterization results in the open versus closed method of pulmonary valvuloplasty. Doyen reported an unsuccessful attempt to relieve pulmonary stenosis by transventricular valvulotomy in 1913.1 In 1948, Sellors ...
