Left ventricular cineangiography was performed in 37 patients with mitral regurgitation. Twenty-one patients had rheumatic mitral valve disease determined by careful surgical and pathologic examination, 10 had papillary muscle dysfunction, and six had chordae tendineae rupture. Fourteen of the 16 patients considered to have nonrheumatic mitral regurgitation were confirmed surgically; the other ...

Functional ischemic mitral regurgitation is a complex disorder with a poor prognosis. Although the underlying anatomical and pathophysiological mechanisms are not entirely clear, it is known that postinfarction left ventricular remodeling is the most significant factor in the development of this mitral valve lesion. Echocardiography and magnetic resonance imaging have made significant contribut...

A 53-year-old woman with a history of hypertension was referred for an echocardiogram by her primary care physician after an unspecified abnormal ECG. The echocardiogram showed normal left ventricular size and function; however, an isolated cleft posterior mitral valve leaflet was identified with concomitant bileaflet prolapse and mild mitral regurgitation. She was subsequently referred to a ca...

Mitral valve repair provides substantial advantages over mitral valve replacement in patients with severe mitral regurgitation. However, because of the possibility of persistent regurgitation, an intraoperative technique is needed to provide an immediate and accurate assessment of the adequacy of the repair before closure of the chest. One hundred patients with pure mitral regurgitation were st...

Mitral valve regurgitation is a relatively common and important heart valve lesion in clinical practice and adequate assessment is fundamental to decision on management, repair or replacement. Disease localised to the posterior mitral valve leaflet or focal involvement of the anterior mitral valve leaflet is most amenable to mitral valve repair, whereas patients with extensive involvement of th...

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 ...

A33-year-old man presented to the hospital with shortness of breath and chest pain. He was subsequently diagnosed with Streptococcus mitis endocarditis involving the aortic valve. The initial echocardiogram revealed moderate aortic valve regurgitation and a normal mitral valve without regurgitation. The patient was treated with afterload reduction and antibiotics. Blood cultures were negative w...

Degenerative mitral valve disease often leads to leaflet prolapse due to chordal elongation or rupture, and resulting in mitral valve regurgitation. Guideline referral for surgical intervention centres primarily on symptoms and ventricular dysfunction. The recommended treatment for degenerative mitral valve disease is mitral valve reconstruction, as opposed to valve replacement with a bioprosth...

OBJECTIVE We evaluated the outcomes of minimally invasive mitral valve surgery via a right anterior thoracotomy approach in patients with isolated severe mitral regurgitation and severely reduced left ventricular systolic function. METHODS We retrospectively reviewed all minimally invasive mitral valve surgeries for mitral regurgitation in patients with an ejection fraction of 35% or less per...
