Although valve repair is preferred over replacement whenever possible, valve replacement may be required in certain patients. In situations where the mitral or tricuspid anatomy are unfavorable and exposure is difficult, seating a prosthetic valve in the annulus through a right mini-thoracotomy approach may be difficult, compared to conventional sternotomy approach. This is complicated by limited tactile feedback in the minimally invasive approach. Herein, we describe several simple maneuvers that facilitate proper prosthetic valve seating and visualization of the posterior annulus during minimally invasive valve operations via right mini-thoracotomy.展开更多
