The low-profile porcine bioprosthesis Liotta was introduced in clinical practice in order to reduce the potential complications related to excessive protrusion of the stent into the left ventricle after mitral valve replacement. Otherwise the particular design of this device seems to determine an excessive stress at the commissural level. We describe a case of acute dysfunction of the Liotta bioprosthesis secondary to commissural tear associated with minimal calcifications that required a reoperation in emergency.
低轮廓猪生物瓣Liotta被引入临床实践，以减少二尖瓣置换术后支架过度突入左心室相关的潜在并发症。否则，该装置的特殊设计似乎会在瓣叶连合处产生过大的应力。我们描述了一例Liotta生物瓣急性功能障碍的病例，该病例继发于瓣叶连合处撕裂并伴有极少钙化，需要紧急再次手术。
