BACKGROUND Rupture of papillary muscle generally happens during acute myocardial infarction and is the cause of acute mitral regurgitation, pulmonary oedema, so it should be promptly recognized and managed. CASE REPORT A patient, 52 year-old, was admitted to the Thoracic Department with fever, general weakness, dyspnea and cough as a case of suspected pneumonia. Two days before the admission ...

The dynamics of acute mitral regurgitation were studied in six open-chest dogs in whom a portion of the anterior leaflet was excised. Phasic mitral and aortic flows were measured electromagnetically and left ventricular filling volume, regurgitant volume (RV) and forward stroke volume (SV) were calculated. The systolic pressure gradient (SPG) between the left ventricle (LV) and left atrium (LA)...

OBJECTIVE To determine the frequency of occurrence of mitral and aortic valvar regurgitation in rheumatic children in whom there was no evidence of carditis acutely or at an earlier attack. DESIGN Colour flow Doppler imaging was used in a non-randomised study of sequentially admitted children who met the criteria for acute rheumatic fever without clinically evident carditis and patients in wh...

A 38-year-old man was admitted with coingestive heart failure due to infective endocarditis. Echocardiography with color Doppler imaging revealed severe aortic regurgitation, mitral valve premature closure and diastolic mitral regurgitation. The flow of the diastolic mitral regurgitation was directed to the posterior wall of the left atrium through just behind the posterior mitral leaflet. The ...

OBJECTIVE This study investigated the feasibility of mitral valve (MV) repair in patients with active or healed infective endocarditis (IE) with mitral regurgitation and evaluated effects on left ventricular (LV) function and structure. METHODS Subjects comprised 19 patients who underwent MV operations for IE between December 2004 and September 2007. MV repair was performed for acute IE in 10...

We present a case of an individual who presented with acute severe mitral regurgitation in the setting of an inferior ST elevation myocardial infarction. Both transthoracic and transesophageal echocardiography demonstrated a posteriorly directed eccentric jet of severe mitral regurgitation with flail anterior mitral valve leaflet attached presumably to the anterior papillary muscle. Intraoperat...

introduction: infective endocarditis is well known to produce neurologic complications from septic emboli, which mandates a multidisciplinary approach between neurosurgery and cardiac surgery. however, literature is not clear as to the optimal interval length between neurosurgery and cardiac surgery.presentation of cases: the first case involves a 60-year-old woman with significant past medical...

d a v p s a o Background. The importance of moderate ischemic itral regurgitation in patients presenting for coronary rtery bypass grafting (CABG) is controversial. Thereore, we tracked the course of unrepaired moderate schemic mitral regurgitation after CABG surgery alone, dentified factors associated with worsening postoperaive ischemic mitral regurgitation, and assessed the imact of unrepair...

Background—Proponents of flexible annuloplasty rings have hypothesized that such devices maintain annular dynamics. This hypothesis is based on the supposition that annular motion is relatively normal in patients undergoing mitral valve repair. We hypothesized that mitral annular dynamics are impaired in ischemic mitral regurgitation and myxomatous mitral regurgitation. Methods and Results—A Ph...
