The advantages of mitral valve repair are lower morbidity and mortality, reduced risk of thromboembolism and endocarditis, improved survival, and better preservation of left ventricular function. The most common cause of degenerative mitral regurgitation is a myxomatous valve with segmental prolapse of the posterior leaflet, a lesion that can be corrected by classical techniques such as quadrangular resection, but other lesions may require more complex surgical techniques, for instance, correction of anterior leaflet prolapse or Barlow disease. Mitral valve repair […]
