Anesthetic Considerations During Minimally Invasive Mitral Valve Surgery

Advances in instruments and visualization tools as well as circulatory systems for cardiopulmonary bypass during the late 1990s have stimulated widespread adoption of minimally invasive mitral valve surgery (MIMVS). Today, MIMVS is the standard approach for many surgeons and institutions. There are multiple benefits of MIMVS. Patient satisfaction and improved cosmesis are important. Additionally, studies have consistently shown faster recovery times and less associated pain with MIMVS. Statistically significant improvement in bleeding, transfusion, incidence of atrial fibrillation, and time to resumption of normal activities with MIMVS has also been shown when comparing MIMVS with conventional mitral surgery. Most important, these benefits have been achieved without sacrificing perioperative safety or durability of surgical repair. Although a steep learning curve still exists given the high level of case complexity, continued development fueled by increasing patient demand may allow for even further expansion in the use of minimal invasive techniques.
