Right minithoracotomy and resternotomy approach in patients undergoing a redo mitral valve procedure.
Abstract
OBJECTIVES\nA minimally invasive approach via a thoracotomy is an alternative in challenging redo cardiac procedures. Our goal was to present our early postoperative experience with minimally invasive cardiac surgery via a right minithoracotomy (minimally invasive) and resternotomy in patients undergoing a mitral valve procedure as a reoperation.\n\n\nMETHODS\nFrom 2017 until 2020, reoperation of the mitral valve was performed through a right-sided minithoracotomy in 27 patients and via a resternotomy in 26 patients. Patients with femoral vessels suitable for cannulation underwent a minimally invasive technique. Patients requiring concomitant procedures regarding the aortic valve were operated on via a resternotomy.\n\n\nRESULTS\nThe mean age was 66\u2009±\u200912\u2009years in the minimally invasive group and 65\u2009±\u200912\u2009years in the whole cohort. The average Society of Thoracic Surgeons score was 11\u2009±\u200910% in the minimally invasive group and 13\u2009±\u20099% in all patients. The majority of the patients underwent reoperation because of severe mitral valve insufficiency (48% and 55%, respectively). The mean time to reoperation was 7\u2009±\u20099\u2009years (minimally invasive group). The 30-day mortality was 4% in the minimally invasive group and 11% in the whole cohort. The blood loss was 566\u2009±\u2009359\u2009ml in the minimally invasive group and 793\u2009±\u2009410\u2009ml totally. There were no postoperative neurological complications in the minimally invasive group and 1 (2%) in the whole cohort. Postoperative echocardiography revealed competent mitral valve/prosthesis function in all patients.\n\n\nCONCLUSIONS\nA minimally invasive approach for a mitral valve reoperation in selected patients is a safe alternative to resternotomy with a low transfusion requirement. Both surgical techniques are associated with good postoperative outcomes.
