bifid cardiac apex is a rare anomaly of human hearts. we report of the case of a 34-year-old man with a previous history of ventricular septal defect (vsd) and subvalvular pulmonary stenosis. he had undergone pulmonary commissurotomy and vsd closure 22 years before he was referred to our center for evaluation of progressive dyspnea. transthoracic echocardiography revealed atrial septal defect (...

Real-time, cross-sectional echocardiograms of the pulmonary valve were recorded in 22 patients with valvular pulmonary stenosis (VPS) (14 mild, eight moderate or severe) and 25 normal subjects. Normally during systole the pulmonary leaflet echoes moved rapidly apart and in the fully opened position lay parallel and in close apposition to the margins of the pulmonary artery. In 20 of 22 patients...

This report describes 3 cases of pulmonary stenosis in the recipient twin in twin-twin transfusion syndrome. Fetal echocardiography showed cardiomegaly, tricuspid valve regurgitation, and increased reverse flow in the inferior vena cava, as signs of congestive heart failure in all 3 cases. We diagnosed 2 cases of pulmonary stenosis by fetal echocardiography prenatally and confirmed our findings...

Fourty-three operations were performed on a total of 41 patients consisting of atrial septal defect, ventricular septal defect, ventricular septal defect with pulmonary stenosis, tetralogy of Fallot, aortic valve stenosis, pulmonary valve stenosis and coarctation of the aorta under hypothermia using intrathoracic rewarming. All patients but 2 cases with tetralogy Fallot have been completely cur...

Transluminal balloon valvuloplasty was used to treat congenital pulmonary valve stenosis in 20 patients. Follow-up cardiac catheterization was performed in 11 patients at intervals of from 2 to 12 months after the procedure. Peak systolic pressure gradient across the pulmonic valve decreased from 68 +/- 27 to 23 +/- 5 mm Hg (p less than .001) after valvuloplasty. There were no complications. Fo...

The electrocardiograms in 32 patients with mitral valve disease have been compared with the pulmonary resistances, the pulmonary artery pressures, and the size of the mitral valve orifice. In patients with pure stenosis if the electrocardiogram showed the pattern of right ventricular hyper-trophy the total pulmonary resistance was usually 1000 dynes seconds cm.-5 or greater. If mitral insuffici...

Isolated pulmonary valve endocarditis is an uncommon clinical entity and is usually associated with intravenous drug abuse. The majority of cases involve the tricuspid valve. Isolated pulmonary valve bacterial endocarditis complicating Triology of Fallot ( which constitutes pulmonary valve stenosis, right ventricular hypertrophy and atrial septal defect) is very rare. A rare complication of a r...

It has been suggested that the maximal amplitude of the pulmonary valve motion following atrial contraction (Amax) may be useful in the clinical evaluation of patients with valvular pulmonary stenosis. To evaluate the specificity and sensitivity of this measurement in children, we reviewed the echocardiograms of the pulmonary valve of 120 subjects: 57 normal individuals, 25 patients with secund...

The feasibility of using balloon dilatation to relieve stenosis caused by dysplasia of the pulmonary valve was assessed in seven patients (five female, mean age two years) with angiographically confirmed dysplasia who were identified among 38 patients with pulmonary valve stenosis selected for balloon dilatation over a two year period. The clinical features in three patients were consistent wit...
