Abstract:
Objective To explore the effect and safety of surgical treatment for hypertrophic obstructive cardiomyopathy (HOCM) with mitral regurgitation (MR) through right mini-thoracotomy. Methods From January 2008 to June 2018, 54 patients with HOCM and moderate-to-severe MR underwent modified Morrow procedure and edge-to-edge mitral valvuloplasty through right mini-thoracotomy, including 31 males and 23 females, with an average age of 47.1±12.6 years. All patients had systolic anterior motion (SAM) phenomenon. Preoperative left ventricular outflow tract pressure gradient (LVOTPG) was 93.6±32.8 mm Hg, interventricular septum thickness (IVST) was 24.8±2.8 mm. Results Surgeries in all patients were completed successfully. No early death or interventricular septal perforation occurred. One (1.9%) patient received permanent pacemaker implantation due to the complete atrial-ventricular block. At discharge, postoperative LVOTPG (18.1±6.2 mm Hg) and IVST (14.5±2.1 mm) were significantly decreased compared with the preoperative values (P<0.05). No MR or SAM was observed in all patients. The follow-up time was 6-132 months, and during this period, no death, MR or SAM occurred. The average LVOTPG was 19.4±5.7 mm Hg, and the average IVST was 14.2±1.5 mm. Conclusion Morrow procedure and edge-to-edge mitral valvuloplasty through right mini-thoracotomy is a safe and effective method for treatment of HOCM with moderate-to-severe MR.
