Application of Echocardiography to Support Transapical Transcatheter Aortic Valve Implantation in Patients with Aortic Regurgitation

To explore the role of echocardiography in pre-procedural,peri-procedural and post-procedural stages of transapical transcatheter aortic valve implantation (TAVI) in patients with aortic regurgitation (AR). 31 patients with pure/dominant AR at a high risk on surgery were enrolled in this study.

Summary:To explore the role of echocardiography in pre-procedural,peri-procedural and post-procedural stages of transapical transcatheter aortic valve implantation (TAVI) in patients with aortic regurgitation (AR). 31 patients with pure/dominant AR at a high risk on surgery were enrolled in this study. The degree of their aortic regurgitation was evaluated before TAVI,as well as the related diameters of aortic root and the left ventricular systolic function measured by transthoracic echocardiography (TTE). TEE was used to reevaluate the valve pathology after general anesthesia. TEE in combination with fluoroscopy provided accurate position of the prosthetic valve for implantation. TEE was also used to monitor complications and to evaluate immediate post-procedure paravalvular regurgitation. The post TAVI follow-up included valve heamodynamic status,complications,left ventricular systolic function and left ventricular mass index (LVMI) measured by TEE. Transapical TAVI was successful in 29 of the 31 patients: 23 exper
