title: Papillary muscles identified by myocardial contrast echocardiography in preparation for percutaneous transluminal septal myocardial ablation.
abstract: In patients with hypertrophic obstructive cardiomyopathy (HOCM), percutaneous transluminal septal myocardial ablation (PTSMA) supplemented by myocardial contrast echocardiography (MCE) can provide a therapeutic benefit. We report a 33-year-old woman with HOCM in which MCE revealed a septal branch artery supplying the postero-medial papillary muscles. Thus, PTSMA was aborted because of the risk of acute mitral regurgitation secondary to papillary muscle dysfunction.
