Effects of varying ethanol dosing in percutaneous septal ablation for obstructive hypertrophic cardiomyopathy on early hemodynamic changes

This prospective, randomized study evaluates the association between ethanol dose and postprocedural hemodynamic changes in 42 patients treated by alcohol septal ablation for obstructive hypertrophic cardiomyopathy. These results suggest that the early course of hemodynamic changes is not related to the use of a small (1 to 2 ml) or standard (>2 ml) dose of ethanol.
