Hemodynamic Response to Exercise in Isolated Pulmonic Stenosis

Hemodynamic effects of valvulotomy in pulmonic stenosis.

Seven patients with mild to moderate pulmonic stenosis with intact ventricular septum were subjected to cardiac catheterization before and from 4 to 18 months after pulmonary valvulotomy. Despite uniform clinical improvement, remarkably slight changes were observed, following surgery, in right ventricular pressure, pulmonary artery pressure, pulmonary artery flow, and pulmonary valve area, when...

Hemodynamic effects of exercise in isolated valvular aortic stenosis.

Hemodynamic data, including simultaneously measured left ventricular and aortic pressures, were obtained from 20 patients with isolated valvular aortic stenosis at rest and during supine leg exercise. Changes in left ventricular end-diastolic pressure during exercise were not significantly related to the severity of aortic stenosis but were correlated with age; patients with abnormal left ventr...

Atrial flutter associated with isolated pulmonic stenosis.

Two adults with severe pulmonic valvular stenosis and atrial flutter are presented. This arrhythmia is apparently a rare complication of this particular form of congenital heart disease. In both cases surgical correction was achieved with the aid of total body perfusion. At the time of surgery, significant tricuspid insufficiency was discovered in both cases. Although the tricuspid valve was no...
