Abstract
In 6 patients undergoing prosthetic mitral valve replacement a ring of Teflon felt, instead of conventional Teflon pledgets, was used because of concern about seating a new prosthesis in a disrupted friable mitral valve annulus. The technique avoided the potential risk of pledget loss in the event of suture breakage and, in these patients, prevented postoperative paraprosthetic mitral valve regurgitation.
摘要
在6例接受人工二尖瓣置换术的患者中，由于担心在破损易碎的二尖瓣环中植入新的人工瓣膜，使用了聚四氟乙烯毡环而不是传统的聚四氟乙烯小片。该技术避免了缝合线断裂时小片丢失的潜在风险，并且在这些患者中防止了人工瓣膜旁二尖瓣反流。
