From July 1983 to December 1992, 145 patients with mitral valvular disease underwent open heart surgery at Chonbuk National University Hospital. Of these patients, 89 patients(61.4%) required mitral valve replacement. 56 patients(38.6%) had
mitral
valve
repair.
There were 32 women and 24 men and the mean age was 34.3 years(range 6 years to 62 years).
There were 23 cases of pure mitral stenosis, 19 cases of mitra regurgitation and 14 cases of mixed mitral valvular disease. The mean duration of symptom was 4.53 years and mean mitral valvular orifice diameter(in cases of pure stenosis and mixed
mitral
valvular lesion) was 0.96cm. According to the NYHA classification, the distribution of patients preoperatively was as follows; class IIa, 15 patients; class IIb, 17 patients; class III, 22 patients; class IV, 2 patients. Four patients(7%) had a
embolic
history preoperatively. 24 patients(43%) were in atrial fibrillation.
In cases of pure mitral stenosis, the technique used included open mitral commissurotomy(21 patients), open mitral commissurotomy with mitral annuloplasty(2 patients). In mixed mitral valvular disease, open mitral commissurotomy(11 patients) and
open
mitral commissurotomy with mitral annuloplasty(1 patient) were performed. In cases of mitral regurgitation, mitral annuloplasty(5 patients), mitral valvuloplasty(6 patients), mitral annuloplasty with valvuloplasty(3 patients) and ring
annuloplasty(5
patients) were performed.
There was one perioperative death related to acute renal failure and sepsis one late death was occured related to heart failure after 10 months postoperatively, One patient required reoperation due to restenosis and no embolic episode was
occured.
After operation, 34 patients were in NYHA functional class I, 20 patients were in class IIa. (Korean J Thoracic Cardiovas Surg 1994; 27:752-8)
