A 63-year-old man was admitted to the hospital for the treatment of annulo-aortic ectasia with severe aortic regurgitation. The aortogram revealed dilatation of the aortic root and severe aortic regurgitation. LVEDVI was 207 ml/m2 but the patient was asymptomatic. Aortic root reconstruction was performed with Cabrol procedure using zero-porosity graft. There was no evidence of bleeding due to this graft and the percent dilatation of this graft was 33%. This zero-porosity graft of knitted Dacron coated with gelatin seems to offer some advantages to the operation. The patient is in stable health today, but perioperative occurrence of VPCs may have owed to diminished LV function caused by severe aortic regurgitation.
一名63岁男性因主动脉瓣环扩张伴严重主动脉瓣反流入院治疗。主动脉造影显示主动脉根部扩张及严重主动脉瓣反流。左心室舒张末期容积指数（LVEDVI）为207ml/m²，但患者无症状。采用零孔隙率移植物通过卡布罗尔手术进行主动脉根部重建。未发现该移植物导致出血的证据，且该移植物的扩张百分比为33%。这种涂有明胶的针织涤纶零孔隙率移植物似乎为手术带来了一些优势。患者目前健康状况稳定，但围手术期室性早搏的发生可能归因于严重主动脉瓣反流导致的左心室功能减退。
