Bilateral mini-thoracotomy for combined minimally invasive direct coronary artery bypass and mitral valve repair.

ABSTRACT

Consistent evidence recognizes minimally invasive valve surgery as the top-tier surgical approach for heart valve pathology. Conversely, the overall adoption of minimally invasive coronary surgery remains low. Notwithstanding, excellent clinical outcomes have been recently reported, further consolidating a technique that addresses major concerns associated with the traditional approach for the most frequently performed cardiac operation, including sternal dehiscence (i.e sternal sparing) and stroke (i.e. no-touch aorta), but that also guarantees a reduced resort to blood transfusions, diminished pain and faster recovery. More to the point, the suitability of minimally invasive strategies for combined coronary and valve procedures remains debateable. Almost no reports of such combined procedures are available in literature and the very few published experiences appear scarce and heterogeneous about the surgical access (i.e. single versus bilateral mini-thoracotomy). However, bilateral mini-thoracotomy has been proposed as a feasible and safe strategy for different cardiac operations like surgical ablation and left ventricular assist device implantation, but also for isolated multivessel minimally invasive coronary surgery. Here, we describe the feasibility of combined minimally invasive mitral valve and coronary surgery performed through bilateral mini-thoracotomy and we report outcomes of our initial series of 3 cases.
