[II-JCKO3-03] Surgical Repair of Congenital Mitral Valve Disease in Pediatric Population
Objective Surgical treatment of congenital mitral valve disease is difficult in pediatric population. This article aims to explore diagnosis and surgical treatment of congenital mitral valve disease in pediatric population.Methods Between January 2008 and December 2015, 76 patients underwent mitral valve repair for congenital mitral valve disease. The average age of repair was 3.8±2.5 years (18 cases <2 years, 7 cases <1 years ). 21 patients had associated cardiac defects. In 52 patients with mitral regurgitation, surgical techniques include clefts closure(16 cases), commissuroplasty(16 cases), annuloplasty(12 cases), chordal shortening(8 cases), anterior/posterior leaflet extension(6 cases). In 24 patients with mitral stenosis , surgical techniques include supramitral ring excision(16 cases), commissures excision(6 cases), papillary muscles spliting(2 cases), chordal detachment and spliting (3 cases).Results There were 3 death in all patients (3.9%), 1 death in mitral regurgitation group (1.9%) and 2 death in mitral stenosis group(8.3%). Reoperation happened in 9 patients. The type of reoperation including mechanical valve replacement(3 cases,2 cases accept reoperation in early followup) and mitral valve repair(6 cases) . There were no death in reoperation patients.Conclusions Surgical repair of congenital mitral mitral valve disease is still facing a huge challenge. Compared to mitral regurgitation, the mortality in mitral stenosis is higher. Some patients need multiple operations, valvoplasty is the first consideration.
