[Usefulness of isovolumic acceleration and tissue Doppler echocardiographic parameters for predicting postoperative functional recovery after heart valve surgery].
INTRODUCTION AND OBJECTIVES Postoperative right ventricular (RV) systolic dysfunction is associated with perioperative myocardial ischemia, hypothermic cardiac arrest, cardiopulmonary bypass and pericardial injury. As myocardial acceleration during isovolumic contraction (IVA) and myocardial velocity during isovolumic contraction (IVV) are little affected by loading conditions, they can predict...
متن کاملEchocardiographic assessment of the level of cardiac compensation in valvular heart disease.
The level of cardiac compensation in valvular disease was studied by relating echocardiographic and cardiac catheterization measurements. Three groups -- compensated, intermediately compensated, and decompensated -- were defined according to the left ventricular angiographic pattern and cardiac output. The echocardiographic ejection indices, percent left ventricular minor diameter shortening, e...
متن کاملValvular heart disease.
Era Before 1950 In 1950, rheumatic valvular heart disease (VHD) was the most common cause of VHD. The link between streptococcal infection and rheumatic fever was established, and a successful trial of penicillin prophylaxis against rheumatic fever was reported.1 In 1944, Jones published a seminal article on diagnosis of rheumatic fever.2 The American Heart Association (AHA) and Circulation pla...
متن کاملValvular heart disease in pregnancy
Valvular heart disease may be a pre-existing complication of pregnancy or it may be diagnosed for the first time during pregnancy. Accurate diagnosis, tailored therapy and an understanding of the physiology and pathophysiology of pregnancy are necessary components of management, best achieved through the use of multidisciplinary clinics. This review outlines the management of specific lesions, ...
متن کاملValvular Heart Disease
324 Malfunction of any of the cardiac valves results in a less efficient circulatory system. Valvular dysfunction causes work overload in one or both ventricles. In extreme cases, resultant congestive heart failure can cause death. More information about etiology, pathogenesis, differential diagnoses, and diagnostic approaches used for evaluation of valvular diseases can be found in chapters 27...
