Between December 1993 and March 1996, 75 patients had undergone subannular procedures in mitral vale reconstruction. Their mean age was 45 years and they consisted of 28 males and 47 females. The cause of mitral disease in 75 patients were
classified as
follow : 29 cases were degenerative, 40 cases were rheumatic, 3 cases were congenital, 2 cases were infectious and 1 cases was ischemic. Average number of mitral anatomical lesion per patient was 3.1 and we used average 1.5 procedures on
subannular
structure in mitral valve per patient. Subannular procedures were chordae shortening 21, chordae transfer 22, new chordae formation 20, papillary muscle splitting 33, shortening of papillary muscle 2. Intraoperative transesophageal
echocardiography
was
carried out for providing an immediate and accurate assessment of the adequacy of the reconstruction. There was no operative death. Patients have been followed up from 2 to 29months, mean 12.5. There were two failures that necessitated
reoperation.
The
mean functional class (NYHA) was 3.19 preoperative and improved to 1.12 postoperatively. After mitral valve repair, the patients were improved hemodynamic, echocardiographic data. In conclusion, subannular procedure in mitral valve repair when
feasible
is stable and safe with a low prevalence of reoperation.
