Transcatheter Aortic Valve Replacemen

Conventional transcatheter aortic valve replacement (TAVR) relies on fluoroscopic and contrast agents. However, in high-risk patients, exposure to ionizing radiation and contrast agents is contraindicated and undesirable. Echocardiography guidance TAVR can offer a feasible and safer strategy for TAVR.

Transcatheter aortic valve replacement (TAVR) has become an established alternative for the treatment of severe symptomatic aortic stenosis irrespective of surgical risk. The development of new-onset left bundle branch block (LBBB) is the most common complication, which impairs outcomes after TAVR. Glucocorticoid has been proven safe and effective in arrythmia after cardiac surgery. The anti-inflammatory effect of glucocorticoid may alleviate the occurrence of LBBB and thus the prognosis. EAGLE-TAVR is a multi-center, randomized, double blind, placebo-controlled trial. A total of 200 patients selected to undergo TAVR will be randomized in a 1:1 ratio to the treatment with intravenous Methylprednisolone 1mg/kg/day or placebo for 3 days started from the day of the procedure. According to the definition of the Valve Academic Research Consortium 3, persistent LBBB is defined as present LBBB at discharge or \>7 days post-TAVR. The primary endpoint is the occurrence of new-onset LBBB at 30 days post TAVR.
