ABSTRACT
Percutaneous transluminal septal myocardial ablation (PTSMA) has been introduced as an alternative to surgery for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). Visualization of the ablation area prior to induction of the chemical necrosis is possible by intraprocedural myocardial contrast echocardiography (MCE). We report on two patients in whom MCE showed opacification of the medial papillary muscle or the left ventricular posterolateral free wall. In both patients the correct ablation area could be identified by MCE after a change of the target vessel, thus avoiding potentially fatal complications due to induction of a necrosis of myocardium distant from the septal target area.
