Periareolar Approach in Minimally Invasive Cardiac Surgery

Overall Goal: To study the feasibility and safety of "periareolar minimally invasive surgery" protocol in patients undergoing periareolar minimally invasive surgery vs. Control group (inframammary approach). * Objective1: Test the hypothesis that, the periareolar approach is more feasible and safer than the inframammary approach. * Objective2: Identify risk factors that are predictive of the need for periareolar approach. * Objective3: Assess outcomes and postoperative results of both periareolar and inframammary approach.
