Methods
Between February 2002 and June 2005, 142 consecutive mitral valve procedures were performed by a single surgeon. Patients whose condition required concomitant coronary artery bypass grafting or aortic valve surgery were excluded subsequently from the study because they were approached obligatorily by sternotomy. Among the remaining patients, 6 patients underwent right thoracotomy mitral valve procedures without robotic assistance, and 1 patient in cardiogenic shock underwent emergent mitral
Results
The robotic minimally invasive and open sternotomy approaches exhibited equivalent preoperative characteristics (Table I) and resulted in equivalent degrees of correction of mitral regurgitation (MR) in repairs and in the need of replacement. Equivalent numbers of patients underwent repairs in the 2 groups (sternotomy, 23/39; robotics, 17/25). Complex mitral valve repairs that entailed leaflet resection and reapproximation, annular plication, sliding annuloplasty, chordal transfer, and GoreTex
Discussion
Since the first robotic-assisted mitral valve procedures were performed independently in 1998 by Carpentier in France and Mohr in Germany, robotic-assisted minimally invasive mitral valve reconstruction has gained significant popularity. A multicenter trial of robotic mitral valve surgery was conducted in the United States and then published in 2005.8 To date there has been only 1 published report of a prospectively randomized comparison between standard sternotomy mitral valve reconstruction
