Chronic Mitral Regurgitation: When the Optimal Timing of Surgical Intervention?
Optimal timing of surgery in mitral regurgitation (MR) is a complex problem that has been studied widely. The pathophysiological mechanism and hemodynamic changes whereby MR exerts its deleterious effects on survival is well recognized. Early reports in the literatures and newer prospective studies suggest that severe MR is not a benign state and it has a high morbidity and eventually mortality...
متن کاملTiming of surgical intervention in chronic mitral regurgitation: is vigilance enough?
Determination of the optimal time for surgical intervention in chronic mitral regurgitation has remained controversial. There are similarly important factors in favor of temporizing with medical treatment alone as there are in support of relatively early surgery (Table 1). Since rheumatic valvulitis may play a subordinate role, in contrast to etiologies such as myxomatous degeneration of the mi...
متن کاملErratum: Surgical Timing of Degenerative Mitral Regurgitation: What to Consider
Severe primary mitral regurgitation (MR) is a progressive condition which engenders significant mortality and morbidity if left untreated. The optimal timing of surgery in patients with MR of degenerative origin continues to be debated, especially for those who are asymptomatic. Apart from symptoms, current authoritative guidelines recommend intervention when there is incipient left ventricular...
متن کاملTiming of surgery in mitral regurgitation.
The mitral valve apparatus is a complex anatomic and functional unit composed of the mitral annulus, valve leaflets, chordae, papillary muscles, and the underlying left ventricular wall. Normal function depends on both normal anatomy of each of these components and on the overall three dimensional relationships of these structures to each other, including the effects of overall left ventricular...
متن کاملChronic Canine Mitral Regurgitation
The mechanism by which ft blockade improves left ventricular dysfunction in various cardiomyopathies has been ascribed to improved contractile function of the myocardium or to improved ,8-adrenergic responsiveness. In this study we tested two hypotheses: (a) that chronic 13 blockade would improve the left ventricular dysfunction which develops in mitral regurgitation, and (b) that an important ...
