Commentary: Surgical treatment of atrial fibrillation at the time of cardiac surgery: Just do it.

Abstract

Central MessageRobotic mitral valve repair has advantages like excellent visualization and agile instrumentation. However, minimally invasive surgery is only appropriate when it does not sacrifice safety or quality.See Article page 75.Almeida and colleagues1Almeida A. Tutungi E. Moten S. Chen Y. Minimally invasive and robotic approaches to mitral valve: robotic is best..J Thorac Cardiovasc Surg Tech. 2021; 10: 75-79Scopus (4) Google Scholar were tasked with answering a question: What is the best minimally invasive mitral valve operation?1Almeida A. Tutungi E. Moten S. Chen Y. Minimally invasive and robotic approaches to mitral valve: robotic is best..J Thorac Cardiovasc Surg Tech. 2021; 10: 75-79Scopus (4) Google Scholar In arguing in favor of a robotic approach, the authors highlight the robotic platform’s articulating instruments, dynamic left atrial retractor, and 3-dimensional camera, which provide clear advantages over a traditional right thoracotomy approach. These features give expert mitral surgeons access to the entire toolbox of mitral repair techniques, such that essentially any degenerative mitral valve repair could be repaired with a robotic approach. The authors also cite several large series that demonstrate the safety, efficacy, and durability of robotic mitral valve repair. With the caveat that robotic mitral surgery is not right for every program, these are compelling arguments for the superiority of robotics over other minimally invasive mitral approaches.That being said, the question: What is the best minimally invasive mitral valve operation? is fundamentally misguided. Just as each mitral valve repair technique must be used in an appropriate valve to achieve a perfect repair, minimally invasive surgical approaches need to be used in carefully selected patients to achieve perfect outcomes.It is our philosophy that minimally invasive surgery is only appropriate when it can be offered without sacrificing safety or quality. We have adopted a conservative screening algorithm, which we use to counsel patients about the most appropriate, data-driven approach for each patient’s anatomy and physiology.2Chemtob R.A. Wierup P.

Patients with more-than-minimal mitral annular calcification are offered open surgery in the event that extensive debridement and reconstruction of the atrioventricular grove is required. Patients with significant aortoilliac calcification are offered open surgery because of the risk of stroke with femoral cannulation and retrograde perfusion of the descending aorta, and patients with small-caliber femoral arteries are offered open surgery because of the risk of distal limb complications. In a series of 1000 patients with isolated degenerative mitral valve disease, this algorithm qualified 60% of patients for robotic surgery. There were no mortalities in the robotic or sternotomy groups, and the rates of stroke were similar (0.5% for robotic and 1.0% for sternotomy).2Chemtob R.A. Wierup P. Mick S.L. Javorski M.J.

In these patients, we offer a hemisternotomy approach, with a J-shaped incision in the right fifth intercostal space. This approach, performed through a 10-cm or smaller skin incision, is cosmetically superior to a standard sternotomy and allows for central aortic cannulation with direct cannulation of the coronary sinus for delivery of retrograde cardioplegia. A full sternotomy approach is generally reserved for patients with challenging body habitus, including pectus excavatum, patients undergoing concomitant coronary bypass surgery, or patients with severe mitral annular calcification.It is also essential to discuss the complex value proposition of robotic mitral surgery.
