Hybrid approach of percutaneous coronary intervention followed by minimally invasive mitral valve surgery: a 5-year single-center experience
Abstract
Background: The current study evaluated the safety and feasibility of staged (“hybrid”) percutaneous coronary intervention (PCI) followed by isolated minimally invasive mitral valve (MV) surgery [PCI + minimally invasive mitral valve surgery (MIMVS)], for patients with concomitant coronary artery and MV disease.
Methods: A total of 93 patients who underwent PCI + MIMVS for coronary artery and MV disease between February 2009 and April 2014 were retrospectively analyzed.
Results: There were 54 (58.1%) men and 39 (41.9%) women. The mean age was 73±8 years, and all patients had severe mitral regurgitation. PCI was performed for single-vessel coronary artery disease in 40 (43%) patients, two-vessel in 49 (52.7%), and three-vessel in 4 (4.3%). Within a median of 48 days (IQR, 18–71) after PCI, 78 (83.9%) patients underwent primary valve surgery, and 15 (16.1%) underwent re-operative valve surgery, with 56 (60.2%) having MV replacement, and 37 (39.8%) having MV repair. Sixty-five (69.9%) patients were being treated with dual anti-platelet therapy at the time of surgery. The median number of transfused intra-operative red blood cell units was 1 (IQR, 0–2), and the intensive care unit and hospital lengths of stay were 46 hours (IQR, 27–76) and 8 days (IQR, 5–11), respectively. Post-operatively, there was 1 (1.1%) cerebrovascular accident, 2 (2.2%) patients developed acute kidney injury, and 4 (4.3%) required a re-operation for bleeding. Thirty-day mortality occurred in 4 (4.3%) patients. At a mean follow-up of 15.3±13.2 months, 3 (3.4%) patients required target-vessel revascularization. The survival rate was 89% and 85% at 1 and 3 years, respectively.
Conclusions: In patients with concomitant coronary artery and MV disease, PCI + MIMVS can be safely performed and is associated with good short-term and follow-up outcomes.
