Trans-ventricular catheter device-based closure of postmyocardial infarction ventricular septal defect following coronary artery bypass grafting: A staged hybrid approach.

A 66-year-old woman with a history of hypertension, ischemic stroke, and rheumatoid arthritis presented to the hospital with severe angina pectoris and dyspnea and was diagnosed with myocardial infarction (MI). Coronary angiography revealed multisystem coronary artery occlusive disease. Due to refractory myocardial ischemia/evolving MI, emergency coronary artery bypass grafting (CABG) was undertaken. Intraoperative transesophageal echocardiography additionally revealed an apical muscular ventricular septal defect (VSD). Concomitant VSD repair was deferred due to the absence of surface evidence of transmural MI for left ventriculotomy, in the setting of pre-existing severe left ventricular dysfunction. An initial totally percutaneous attempt to close the VSD postoperatively failed. A hybrid surgical/catheter-based VSD closure was performed on postoperative day 4, with a successful outcome. The patient did well postoperatively and currently is alive in good condition. To the best of our knowledge, this is the first report of a staged (post-CABG) and hybrid surgical/catheter-based technique without the utilization of cardiopulmonary bypass.
