From: Comparison between three types of stented pericardial aortic valves (Trivalve trial): study protocol for a randomized controlled trial

Primary endpoint

Mean transvalvular gradient (mmHg), six months after surgery

Secondary endpoints

Effective aortic orifice diameter measured by CT-scan and echocardiography compared with the surgical data (mm)

Mean transvalvular gradient (mmHg), at day seven after surgery

Aortic bioprosthesis orifice area (m2), six months after surgery

 

Diameter of the aortic orifice measured by a flat-head candle compared with the size of the implanted bioprosthesis (mm)
