Papillary muscles identified by myocardial contrast echocardiography in preparation for percutaneous transluminal septal myocardial ablation.
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.
