Aortic surgeryTAVIBackground: It is known that coronary heart surgery leads to varying degrees of cardiac autonomic derangement, clinically detectable as depression of heart rate variability (HRV) parameters. Fewstudies report that also surgical replacement of the aortic valve (SAVR) may lead to HRV...
EuroPCR 2024 目前对于大多数有严重症状且不适合外科手术的主动脉瓣狭窄的患者,经导管主动脉瓣置换术(transcatheter aortic valve replacement,TAVR)已经成为一种主要且安全有效的微创介入治疗方法。目前TAVR瓣膜类型按照扩张模式分为两种,...
主动脉瓣狭窄(Aortic Stenosis, AS)是一种常见的心脏瓣膜疾病,对老年人的寿命和生活质量有着显著影响。在中国,因二叶瓣(Bicuspid Aortic Valve, BAV)患者比例相对较高,AS往往更易且更早地发生。研究指出,二叶瓣患者常伴有升主动脉扩...

We describe the case of a 61-year-old male with a giant aortic root aneurysm associated with chronic aortic Type A dissection. The patient had been operated on 16 years before due to aortic annuloectasia with mechanical valve replacement. The patient underwent revision aortic surgery with a Ben...
Repair of the acute aortic insufficiency associated with type A aortic dissection is now preferred to valve replacement. This is generally achieved by resuspending the aortic valve using different types of suturing techniques, with sutures usually passing through the aortic wall, which causes bleeding ...

Ascending aorta hemiarch replacement with aortic valve resuspension, two-vessel coronary artery bypass grafting, and left atrial appendage clipping were performed successfully. Conclusions Pre-operative imaging can be considered in a select group of acute type A aortic dissections that present without ...
Quadricuspid aortic valve (QAV) is a rare congenital anomaly characterized by the presence of four cusps instead of the usual three. It is estimated to occur in less than 0.05% of the population, with Type A (four equal-sized leaflets) accounting for rou
Valve-in-Valve Transcatheter Aortic Valve Replacement: From Pre-Procedural Planning to Procedural Scenarios and Possible Complications Over the last decades, bioprosthetic heart valves (BHV) have been increasingly implanted instead of mechanical valves in patients undergoing surgical aorti...
