May offer a repair option in restrictive rheumatic MR; hypothesis-generating and requires prospective validation before wider use.
It has been established that mitral valve (MV) repair is preferred over replacement in patients with mitral regurgitation (MR) caused by degenerative disease. In contrast, valve reconstruction for rheumatic MR remains controversial. Type IIIa MR due to rheumatic leaflet restriction often renders valve repair challenging and may predict a less successful repair. However, the utilization of leaflet mobilization and extension with autologous pericardium in order to increase leaflet area and surface of coaptation may achieve satisfactory results (1-3). This article represents our single-center experience of leaflet extension in rheumatic MR, with emphasis on description of the technique including tips on safeguards and pitfalls.
