ABSTRACT
Objective:
To assess the effect of percutaneous transluminal septal myocardial ablation (PTSMA) on mid- to long-term left ventricular diastolic function in patients with hypertrophic obstructive cardiomyopathy (HOCM) by real-time three-dimensional echocardiography (RT-3DE).Methods:
A total of 46 HOCM patients who received 2DE and RT-3DE examination before and after (with the mean of 18.8 months) PTSMA were studied. The ratios of E/A and E/Ea were analyzed, RT-3DE was conducted to collect the images, to obtain 17-segmant volume-time curve and to calculate the parameters of rEDV, rESV, rSV and rPFR respectively.Results:
The follow-up echocardiography in all 46 patients indicated that the ratio of E/Ea decreased after the operation (12.04 ± 3.29) vs (15.70 ± 5.68),P<0.001, the rSV of left ventricular anterior wall middle segment and anterior septal middle segment decreased after the operation,P<0.05, while the rPFR of anterior septal middle segment, rear septal middle segment and apical segment increased,P<0.05.Conclusion:
PTSMA may improve local left ventricular diastolic function in HOCM patients, RT-3DE provides a new method and viewing angle for HOCM evaluation.
