Premature closure of the mitral and tricuspid valves.
Premature closure of an atrioventricular valve was observed in 80 of a group of 519 subjects catheterized for aortic insufficiency (Al) or mitral insufficliency (MI), or both. Sole premature mitral closure (PMC) was present in nine subjects, sole premature tricuspid closure (PTC) in 40, and combined PMC and PTC in 31. Clinically PMC was associated with a first sound that was soft or absent in 7...
متن کاملMitral valve abnormalities in congestive heart failure
itral regurgitation (MR) of at least mild severity is present n up to 90% of patients with advanced congestive heart ailure (CHF) due to systolic dysfunction (1). It had long een assumed that MR results primarily from left ventriclar (LV) and mitral annular enlargement due to pathologic emodeling, with contributions as well from regional wall otion abnormalities and papillary muscle dysfunction...
متن کاملMitral and Tricuspid Valve Closure
Echocardiography was used to evaluate mitral and tricuspid valve closure in patients 1 day to 20 years of age. When possible, simultaneous phonocardiograms were obtained. The difference in time between the Q wave of the electrocardiogram and mitral closure and between Q and tricuspid closure was designated the delta value (A). Four groups of patients were assessed: 1) normals (40), secundum atr...
متن کاملTricuspid incompetence and right ventricular output in congestive heart failure.
Studies of the right atrial pressure and flow curves in patients with cardiac failure show that with a venous pressure of more than 8 mm. Hg, increasing amounts of functional tricuspid regurgitation may occur (Muller and Shillingford, 1954; Korner and Shillingford, 1954). If the forward flow is maintained, backflow through the valve will add a variable amount to the right ventricular stroke vol...
متن کاملCONGESTIVE HEART FAILURE IN CHILDREN: A SURVEY OF 114 PATIENTS
During a period of four years between June, IS, 1988 to June, IS, 1992 one hundred and fourteen patients with congestive heart failure (CHF) were admitted to the pediatric department of Taleghani General Hospital. During the above period, 192 patients with heart disease were hospitalized at this department and CHF was the cause of admission in 59.4% of them. Congenital heart disease (CHO) w...
