心衰患者的外科左室减容术能取得心功能改善和临床疗效,其经外科手术方式切除左室前后乳头肌之间的心肌,给心衰患者扩张的左室进行整形术,恢复了原来的几何形态,提高了心功能,而心肌锚定装置治疗心衰可视为导管介入性左室减容术。这种治疗不需体外循环,仅通过导管介入技术锚定前壁已坏死且无收缩功能的心肌,恢复左室的几何形态和功能。与外科心室减容术相比,属于一种侵入性相对小的手术,其不切除左室游离壁的坏死心肌,不需缝线和补片,因而对左室功能破坏性轻。目前已有2组临床试验进行晚期缺血性心肌病患者行心肌
Surgical left ventricular volume reduction in patients with heart failure can achieve cardiac function improvement and clinical efficacy of surgical removal of the left ventricular before and after the myocardium between the papillary muscles, heart failure patients to expand the left ventricle for plastic surgery, restored the original Geometry, improve heart function, and myocardial anchors treatment of heart failure can be considered as catheter-mediated left ventricular volume reduction. This treatment does not require cardiopulmonary bypass, only by catheterization of anchoring the anterior wall has been necrosis and non-systolic myocardial function, restore left ventricular geometry and function. In contrast to surgical ventricular volume reduction, a less invasive surgery that does not remove necrotic myocardium from the free wall of the left ventricle, requires no sutures and patches and therefore is less damaging to left ventricular function. There are currently two groups of patients with clinical trials of advanced ischemic cardiomyopathy
