Impact of septal myectomy on diastolic function in patients with obstructive hypertrophic cardiomyopathy

The impact of septal myectomy on diastolic function in patients with obstructive hypertrophic cardiomyopathy is not well studied.A transcatheter hemodynamic study was performed before and 3 to 6 months after septal myectomy in 12 patients with obstructive hypertrophic cardiomyopathy (HCM).Postoperative hemodynamic studies were done 4.4±1.2 months after myectomy. The left ventricular outflow tract peak-to-peak gradient decreased from 83.2±43.3...
