ABSTRACT
Objective To evaluate the effect of the percutaneous transluminal septal myocardial ablation(PTSMA)on the left ventricular function in patients with hypertrophic obstructive cardiomyopathy(HOCM).Methods All HOCM patients underwent echocardiogram measurements before and after the PTSMA procedure.The peak velocity of mitral annulus was measured at Doppler tissue pulsed wave mode.Doppler tissue imaging(DTI)was obtained at the 4- and 2-chamber apical view,and the peak systolic(Sa),early diastolic(Ea),and late diastolic(Aa)myocardial velocities of mitral annulus was measured at the long apical view.Results Compared with the velocity parameters before the PTSMA procedure,the peak Sa and Ea after the PTSMA were significantly lower while Aa was un-significantly lower.Conclusions In patients with HOCM,the diastolic and systolic function of the left ventricle decreased after the PTSMA procedure.
