Mitral valve reconstruction for mitral insufficiency

摘要: Mitral valve reconstruction is now the procedure of choice for many mitral regurgitant lesions. Early enthusiasm and technical advances in plastic were overshadowed by development prosthetic bioprosthetic valves. With long-term follow-up studies came realization that complication rates valves durability bioprostheses less than ideal. The use annuloplasty rings standardization repair techniques have made these procedures more universally reliable excellent results reproducible. Due to pathological diversity regurgitation, different are used correct various Many centers reporting hospital mortality, survival, freedom from thromboembolism, reoperation, infective endocarditis, valve-related complications compare favorably with those following replacement. preservation papillary muscles chordae tendinea during reconstruction, as well a lack foreign materials, contribute enhanced systolic function improved survival lower compared advances, indications expanded encompass broader lesions earlier operative intervention.
