Filter by:The objective of this trial is to confirm that the modifications to tissue processing, valve sterilization and packaging do not raise any new questions of safety and effectiveness in subjects who require replacement of their native or prosthetic aortic or mitral valve.
The purpose of this study is to evaluate the immediately clinic and ultramicroscopic myocardial cellular ischemia and reperfusion to replace of the mitral valve using arrested heart versus on-pump empty beating heart surgical techniques.
Vasoconstrictive signaling via endothelin receptors is not limited to primary pulmonary arterial hypertension, but has also been documented in secondary pulmonary hypertension due to congestive heart failure, including cardiac valve disease. The investigators aim to examine the clinical and physiologic effects of bosentan therapy in patients with secondary pulmonary hypertension due to severe, inoperable cardiac valve disease, using a single-center, prospective, open-label, non-randomized study of oral bosentan in outpatients with severe mitral stenosis due to childhood rheumatoid fever. Primary end-point will be exercise capacity at six months determined by six-minute walking distance and cardiopulmonary exercise testing. Secondary end-points will be symptomatic relief, echocardiographic left ventricular function and pulmonary pressure, serum pro-brain natriuretic peptide, and adverse events at six months.
The purpose of this study is to study the effect of Ivabradine vs Atenolol on heart rate and effort tolerance in patients with mild to moderate mitral stenosis and normal sinus rhythm.
