The mechanics of left ventricular contraction were studied during diagnostic cardiac catheterization using high-speed cineangiography in 11 patients with severe chronic mitral regurgitation. Compared with a group of previously studied normal subjects, most of the patients with mitral regurgitation demonstrated a reduced velocity of shortening (Vf) during ejection at maximum wall stress, average...

Sensitivity and specificity of detection of mitral regurgitation was assessed by range-gated Doppler echocardiography. The degree of mitral regurgitation was also estimated by the depth and width of the regurgitant jet detected with Doppler and compared with that assessed by left ventriculography. Of 47 patients with an adequate Doppler study, 24 had no mitral regurgitation by ventriculography....

OBJECTIVES Transapical off-pump mitral valve repair using the NeoChord device has been proposed to treat degenerative mitral valve regurgitation. This prospective study sought to evaluate acute safety and efficacy of this innovative, minimally invasive, transcatheter mitral valve repair approach. METHODS Symptomatic patients with severe mitral regurgitation (MR) were selected if they presente...

Four patients are presented who developed acute mitral regurgitation 5 days, 2, 3, and 18 months, respectively, before cardiac catheterization. The hemodynamic findings in the three early cases resemble those found in the presence of a constricting pericardium: left and right ventricular, as well as left and right atrial pressures, equilibrated during diastole. As expected, giant left atrial v ...

Between 1970 and 1981, 12% of patients undergoing mitral valve surgery were found to have chordal rupture. Spontaneous or primary rupture accounted for 74.6% of patients (primary group); in the remainder (secondary group) chordal rupture complicated chronic rheumatic valvular disease (8.9%), bacterial endocarditis on both normal (8.5%) and rheumatic valves (4.7%), ischaemic heart disease (2.3%)...

A murmur of mitral regurgitation in patients with congestive heart failure after an acute myocardial infarction suggests a surgically correctable cause of the heart failure. Six patients who presented in this manner and who later underwent surgery have been evaluated by two-dimensional echocardiography (2DE). The underlying anatomical cause of the mitral regurgitation was correctly identified a...

We report the case of a 71-year-old man hospitalized for acute heart failure. Transthoracic and transesophageal echocardiography showed mitral valve aneurysm (MVA) rupture and severe mitral regurgitation. No vegetations but significant aortic regurgitation were also observed. MVA perforation is a rare life-threatening condition that typically occurs as a complication of endocarditis but may als...

Ischemic mitral regurgitation (IMR) has been recognized as an important complication after acute myocardial infarction (AMI) and is known to worsen patients’ prognoses even if the degree of mitral regurgitation (MR) is mild to moderate. However, the majority of previously published studies have been based on the severity of IMR in the subacute or chronic time period of myocardial infarction, wi...

Adult onset Still's disease (AOSD) is an uncommon acute systemic inflammatory disease of unknown origin. The clinical features include high spiking fever, arthralgia or arthritis, transient maculopapular rash, lymphadenopathy, hepatosplenomegaly, and serositis. Pericarditis is the most common cardiac manifestation of AOSD and occurs in approximately 30% of cases. A simultaneous occurrence of ra...
