title: The impact of percutaneous coronary intervention on ischemic mitral regurgitation.
abstract: OBJECTIVE
  The study aim was to determine if significant ischemic mitral regurgitation (IMR) is adequately addressed in patients undergoing multi-vessel percutaneous coronary intervention (PCI).
  
  
  METHODS
  The cardiac catheterization laboratory database at the authors' institution was accessed over a five-year interval to identify those patients who had undergone multi-vessel PCI. Both, pre- and post-revascularization echocardiographic data were retrieved, and clinical data, MR presence and severity, and outcomes were each assessed.
  
  
  RESULTS
  In total, 150 patients (100 males, 50 females; mean age 63 +/- 12 years) underwent PCI. Of these 150 patients, pre-procedural echocardiograms were not performed in 54 cases (35%); hence, the study group comprised 96 patients with both pre- and postprocedural echocardiograms. Of these patients, 21 (22%) had moderate or greater (2+) IMR. The severity of the IMR did not change significantly after multivessel PCI (2 +/- 0.8+ preoperatively versus 1.9 +/- 1.0+ postoperatively).
  
  
  CONCLUSIONS
  Clinically significant IMR occurred not infrequently among patients treated with multivessel PCI, but the severity did not change with percutaneous revascularization, despite this being predominantly complete. In more than one-third of the patients, adequate pre-PCI echocardiography was unavailable, which suggested the possibility that not all IMR had been identified.
