Edge-to-edge mitral repair: gradients and three-dimensional annular dynamics in vivo during inotropic stimulation.
Eur J Cardiothorac Surg. 2001; (4): 431-7
The edge-to-edge (Alfieri) mitral repair technique appears to be clinically promising, but the potential for functional mitral stenosis, especially with exercise, remains a concern. We used the myocardial marker method combined with Doppler echocardiography to evaluate mitral annular (MA) three-dimensional (3-D) dynamics and transvalvular gradients after leaflet approximation before and during dobutamine infusion.
