We aimed to evaluate left ventricle twist mechanics in mid-ventricular obstructive and apical type of hypertrophic cardiomyopathy and changes induced by myectomy. We studied 3 consecutive patients by cardiac magnetic resonance preoperatively and 6 weeks after myectomy. We calculated the apical and basal rotations at the base and apex respectively. All 3 patients underwent myectomy by the standard described technique. The basal rotations remained the same, while there was an improvement in the maximal apical rotation from 0.385 ± 0.3975° to 0.9086 ± 1.1751°. In hypertrophic cardiomyopathy with mid-ventricular obstruction and apical hypertrophy, there is decreased apical rotation, which improves after myectomy.
