The case is presented of a 15-month-old male, affected by severe mitral valve regurgitation associated to aortic coarctation. The surgical treatment consisted in replacement of the mitral valve by a Hancock prosthesis followed, at a second state, by resection of the coarctation. The mitral insufficiency was secondary to an anomaly of the subvalvular apparatus of the "Parachute Valve" type. The incidence of defects associated to congenital mitral insufficiency is commented. The surgical indications for replacement or repair of these anomalies in infancy are discussed, and the surgical results achieved to data are analysed. Emphasis is made on the convenience, in case the corrective procedure requires valvular replacement, of implanting a low-profile biological prosthesis, which does not require anticoagulant therapy.
本文介绍了一名15个月大的男性病例，该患者患有与主动脉缩窄相关的严重二尖瓣反流。手术治疗包括先用汉考克人工瓣膜置换二尖瓣，二期再行主动脉缩窄切除术。二尖瓣关闭不全继发于“降落伞瓣”型瓣下装置异常。文中对与先天性二尖瓣关闭不全相关的缺陷发生率进行了评论。讨论了婴儿期这些异常的置换或修复手术指征，并分析了目前已取得的手术结果。重点强调了在矫正手术需要瓣膜置换的情况下，植入无需抗凝治疗的低轮廓生物人工瓣膜的便利性。
