OBJECTIVE: The optimal treatment strategy in patients with coronary artery disease and ischemic mitral regurgitation (IMR) remains controversial. A staged approach of percutaneous coronary intervention (PCI) followed by minimally invasive valve surgery, rather than combined median sternotomy coronary artery bypass and valve surgery, may be a viable alternative.
METHODS: We retrospectively evaluated 31 consecutive patients with coronary artery disease and severe IMR who underwent a staged procedure at our institution between February 2009 and April 2014.
RESULTS: The mean ± SD age, preoperative left ventricular ejection fraction, and mitral regurgitation grade were 72 ± 7 years, 35% ± 11%, and 3.6 ± 0.6, respectively. The mean ± SD Society of Thoracic Surgeons-predicted mortality score was 5.1% ± 4.2%. Percutaneous coronary intervention was performed for 1- and 2-vessel disease in 22 patients (71%) and 9 patients (29%), respectively, with 23 patients (74%) having drug-eluting stents placed. Minimally invasive valve surgery was performed within a median of 36 days after PCI, with 61% of the patients being on dual antiplatelet therapy. Postoperatively, there was 1 case of acute kidney injury, 1 case of reoperation for bleeding, and no cerebrovascular accidents. The 30-day mortality was 3%. The median total hospital length of stay was 8 days (interquartile range, 7-10). At a mean ± SD follow-up of 2.4 ± 1.6 years, 2 patients required PCI for target-vessel revascularization. Actuarial survival at 1 and 5 years was 84% and 80%, respectively.
CONCLUSIONS: A staged approach in patients with coronary artery disease and IMR can be performed with a low perioperative morbidity and good midterm survival.
