Percutaneous septal ablation with absorbable gelatin sponge in hypertrophic obstructive cardiomyopathy.
The treatment of the hypertrophic obstructive cardiomyopathy (HOCM) by percutaneous transluminal septal myocardial ablation (PTSMA) with ethanol injection has greatly improved in the last years. This report describes the case of a patient with symptomatic drug-refractory HOCM who underwent an unsuccessful attempt to thrombose the septal artery by PTSMA with alcohol. It has therefore been decided to use small absorbant gelatin sponge (AGS) particles, obtaining immediate thrombotic occlusion of the artery and excellent hemodynamic results with immediate and permanent disappearance of the gradient. The patient progressed satisfactorily and displayed lower than average creatine kinase levels in comparison to the rest of our PTMSA patients. After 2 years of follow-up he still remains asymptomatic and without any gradient. These results suggest that PTSMA with AGS could be a valuable alternative treatment of HOCM.
