Surgical treatment for hypertrophic obstructive cardiomyopathy associated with aortic stenosis / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective     To evaluate the clinical and follow-up results of the surgical treatment for hypertrophic obstructive cardiomyopathy associated with aortic stenosis. Methods     We retrospectively analyzed the clinical data of the patients with hypertrophic obstructive cardiomyopathy plus aortic stenosis in our hospital from February 2008 to October 2015. There were 4 males and 3 females aged 55.6 ± 7.5 years. All the patients were received concomitant aortic valvulopasty at the time of modified extended Morrow procedure. Echocardiographic data and major complications were recorded through the outpatient clinic and telephone. Results     The postoperative ventricular septal thickness, left ventricular outflow tract gradient and aortic gradient were significantly lower than those in preoperation with statistical differences (P<0.05). During the mean follow-up 25.6 ± 28.2 months period, 1 patient died of cerebral hemorrhage, 1 patient was implanted a permanent pacemaker, and 1 patient had a postoperative new-onset atrial fibrillation. All patients had a satisfied prosthetic valve function and the left ventricular outflow tract gradient. The patient's symptoms and heart function significantly improved postoperatively. Conclusion     For patients with hypertrophic obstructive cardiomyopathy associated with moderate to severe aortic stenosis, concomitant aortic valvulopasty at the time of modified extended Morrow procedure is an appropriate and effective treatment, which can significantly alleviate the clinical symptoms, and improve quality of life with a satisfied prognosis.
