The goal of this case-control study was to evaluate the long-term effects on cardiac dimensions, cardiac function and coronary circulation in patients with aortic regurgitation (AR) and left ventricular dilatation undergoing aortic valve replacement and application of the Acorn CorCap cardiac support device Of 10 patients with AR and ventricular dilatation who had a mechanical aortic valve implanted, 5 in addition received the cardiac support device. Cardiac dimensions and cardiac function were measured by echocardiography preoperatively and 1, 5 and 10 years postoperatively. The coronary circulation was assessed by computed tomography angiography. After aortic valve replacement, there was a rapid and sustained decrease in cardiac dimensions. This result did not differ after application of the cardiac support device. Improvement in cardiac function remained unchanged in both groups at the 10-year follow-up. None of the patients had developed any signs of coronary artery disease. Application of the Acorn CorCap cardiac support device in patients with AR and left ventricular dilatation did not add to the reversed remodelling or cardiac function at the long-term follow-up compared to aortic valve replacement alone.

主动脉瓣关闭不全患者被动围堵手术的长期随访

本病例对照研究的目的是评估接受主动脉瓣置换术和应用 Acorn CorCap 心脏支持装置的主动脉瓣关闭不全 (AR) 和左心室扩张患者对心脏尺寸、心脏功能和冠状动脉循环的长期影响在植入机械主动脉瓣的 10 名 AR 和心室扩张患者中，另外 5 名接受了心脏支持装置。术前和术后 1、5 和 10 年通过超声心动图测量心脏尺寸和心功能。通过计算机断层扫描血管造影评估冠状动脉循环。主动脉瓣置换术后，心脏尺寸迅速而持续地减小。该结果在应用心脏支持装置后没有差异。在 10 年的随访中，两组的心功能改善保持不变。没有患者出现任何冠状动脉疾病的迹象。与单独的主动脉瓣置换相比，在长期随访中，Acorn CorCap 心脏支持装置在 AR 和左心室扩张患者中的应用并未增加逆转重塑或心脏功能。
