Abstract
We report first intracardiac echocardiography (ICE) guided alcohol septal ablation (ASA) performed in the Czech Republic. A 60-year old male with hypertrophic obstructive cardiomyopathy underwent this procedure for NYHA class III dyspnea refractory to optimal medical treatment.
The catheter-based ASA was performed as previously described [1]. In this case, ICE was used to guide the procedure instead of transthoracic echocardiography (TTE).
Hypertrophied basal interventricular septum was well visualized with ICE (panel A). Contrast enhanced ICE was performed to assess the perfusion area of the selected septal branch prior to ASA (panel B).
Left ventricular outflow gradient (LVOG) prior to ASA was around 50 mmHg (panel C). The procedure led to immediate LVOG decrease (panel D)
