3D打印指导下经心尖入路心肌切除术治疗心尖肥厚型心肌病一例

Transapical approach under 3D printing guidance for myectomy in apical hypertrophic cardiomyopathy:A case report

本文报道了1例26岁男性心尖肥厚型心肌病患者。术前利用3D建模与打印技术对肥厚心肌的位置和切除范围作出准确评估。手术采取经心尖入路切除肥厚心肌,术中探查与术前3D建模描述一致。患者顺利接受手术,体外循环时间为117 min,主动脉阻断时间为57 min,术后住院时间7 d。住院期间无并发症,术后复查彩色超声提示左室腔血流通畅。本病例为心尖肥厚型心肌病患者的诊疗提供了参考。

We reported a 26-year-old male who was diagnosed with apical hypertrophic cardiomyopathy with left ventricular aneurysm.The location of the hypertrophic myocardium and the extent of resection were accurately assessed preoperatively using 3D modeling and printing technology.Myectomy was performed via transapical approach,and the intraoperative exploration was consistent with the description of the preoperative 3D modeling.The patient underwent the surgery successfully without any complications during the hospitalization,and the cardiopulmonary bypass time was117 min,the aortic cross-clamping time was 57 min,and the hospital stay time was 7 d.The postoperative echocardiography demonstrated left ventricular cavity flow patency.This case provides a reference for the management of patients with apical hypertrophic cardiomyopathy.
