  • Barlow's disease with mitral annular calcification encompassing the subvalvular apparatus, including the valve leaflet and chordae, is extremely rare, and mitral valve repair in such cases is challenging. We report a case of a 60-year-old woman with mitral valve regurgitation that was successfully controlled by resecting the rough zone of P2 and calcifications on the excess leaflet regions and subvalvular apparatus, while retaining the calcification of P3 and implanting artificial chordae and an annuloplasty ring. Mitral valve repair for such cases requires an individualized and compounded surgical strategy for the technique to treat Barlow's disease and manage calcification to control mitral regurgitation.

  • Surgical treatment is possible for the obstructive form of hypertrophic cardiomyopathy and transaortic left ventricular septal myectomy and myotomy has been the procedure of choice. If coexisting intrinsic mitral valve disease exists, mitral valve replacement has been performed. But abnormal systolic anterior motion of anterior mitral leaflet[SAM] with intrinsic normal mitral valve disease is the typical feature of IHSS and we prefer not to replace mitral valve. 3 patients underwent transaortic myotomy and myectomy for IHSS with mitral regurgitation. 2 patients of them have coexisting intrinsic mitral valve diseases such as mitral valve vegetation and chorda rupture. Concomittent mitral valve replacement were performed. 1 patient shows SAM of mitral anterior leaflet but has intrinsic normal mitral valve morphologically and transepicardial echocardiogram and direct monitoring of pressure gradient during the operative procedure gives better information for subsided mitral regurgitation. Post operative course during the 12 months follow-up was uneventful.

  • 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 mitral regurgitation and 14 cases of mixedmitral valvular disease. The mean duration of symptom was 4.53 years and mean mitral valvularorifice diameter[in cases of pure stenosis and mixed mitral valvular lesion] was 0.96 cm. According to the NYHA classification, the distribution of patients preoperatively was as follows; class IIa, 15 patients; class lib, 17 patients; class III, 22 patients; class IV, 2 patients. Four patients[7%] had an embolic history preoperatively. 24 patients[ 43 %] were in atrial fibrillation. In cases of pure mitral stenosis, the technique used included open mitral commissurotomy[21atients], open mitral commissurotomy with mitral annuloplasty[2 patients]. In mixed mitral valvular disease, open mitral commissurotomy[ll patients] and open mitral commissurotomy with mitral annuloplasty[l 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 occurred 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.

  • Author compared the effect of surgical methods between 40 patients who received mitral valve replacement with complete excision of the mitral valve[resected group] and 41 patients who received mitral valve replacement with preservation of posterior chorda tendineae and posterior mitral leaflet[preserved group] from 1985. 2. to 1989. 4. at cardiothoracic department of Pusan National University Hospital.v 1. There was no significant difference between the preserved group and resected group in cardiopulmonary bypass time and aortic cross clamping time and NYHA classification. 2. In preserved group of Mitral stenosis and Mitral regurgitation, the left ventricular functions were much improved after mitral valve replacement than resected group, but there was not so difference between the preserved group and reserved group in Mitral steno-regurgitation. 3. There were remarkable decrease in complication rate in preserved group compared to resected group. And also the death rates were remarkably decreased in preserved group which was 4.9% compared to resected group which was 17.5%. As the preservation of the posterior mitral leaflet and chorda tendineae during mitral valve replacement in mitral valve disease showed significantly improved effects in the maintaining of left ventricular function and reducing the postoperative complication, I assume the preservation of posterior mitral leaflet and chordae during mitral valve replacement will bring better result.

  • We evaluated 68 patients with mitral valve disease who underwent mitral valve replacement from April, 1986, to December, 1988. Among them 20 patients showed increased systolic pulmonary arterial pressure greater than 60 mmHg and postoperative hemodynamic data were obtained in 19 patients average 13 months after mitral valve replacement. The results were as followings. 1. Average pulmonary systolic pressure decreased from 84.8$\pm$4.5 preoperatively to 33. 0$\pm$1.9mmHg postoperatively[P<0.001]. 2. Average pulmonary vascular resistance index decreased from 1425$\pm$148 preoperatively to 287+35.8 dyne * sec * cm2 * m postoperatively[P<0.001]. 3. Average cardiac index rose from 1.927$\pm$0.169 preoperatively to 2.625$\pm$0.159 L/min/m2 postoperatively [P <0.005]. This study shows that pulmonary hypertension and the increased pulmonary vascular resistance index due to mitral valve disease can regress significantly after mitral valve replacement.

  • Mitral valve disease is the most common disease of the acquired heart diseases, and atrial septal defect is also one of common congenital heart diseases. Coexistence of these two lesions is rare, but of great hemodynamic interest. Among 443 cases with mitral valve disease and 90 cases with atrial septal defect experienced in the Department of Thoracic Surgery, Seoul National University Hospital, there were 6 cases with atrial septal defect complicated by mitral valve disease. 1. Of the 6 patients, four were female and two were male. The age was ranged from 18 to 46. 2. Atrial septal defect was ostium secundum type in all cases, and the mitral valvular lesions were regurgitation in four and stenosis in two. Type II ventricular septal defect was also combined in one of the cases. 3. The atrial septal defect was corrected by, primary closure and the mitral valve was replaced with the prosthetic or bioprosthetic valve in all cases. The combined ventricular septal defect was closed using Teflon felt patch. 4. The operative result was good except in one who was expired of bacterial endocarditis 4 months after hospital discharge.

  • Among 25 consecutive cases having undergone mitral valve surgery between March 1991 and June 1992 in Gill General Hospital, 11 patients[44%] who had undergone mitral valve reconstruction using prosthetic rings is evaluated and presented. Patients` mean age is 43 + 19 years[range:16-72], and they are consisted with 4 males and 7 females. Mitral valve insufficiency is due to degenerative disease in 6 cases[55%] and rheumatic disease in 5 patients[45%]. Carpentier`s functional classification I is 2 cases, II is 6 cases, and III is 2 cases. Surgical techniques include prosthetic ring annuloplasty[11 patients, 100%], chorda shortening[6, 55%], leaflet mobilization[4,36%], new chorda formation[2, 18%], chorda transposition[1, 9%] commissurotomy[3, 27%], and papillary muscle splitting[3, 27%]. Average number of mitral anatomic lesions per patient are 2.7 and we used average 2.8 procedures upon mitral valve apparatus per patient. There were no surgical mortality and no late valve related admission during the mean follow up period of 17 months. The mean functional class[NYHA] is 2.81 preoperatively and improved to 1.10 postoperatively. Doppler echocardiography showed much improvement from grade II MR [1 case], grade III MR [1 case] and 9 cases of grade IV MR to 6 cases of patients showed no MR, only trace MR in 4 cases, and grade I MR was found only in one patient with NYHA functional class II postoperatively. The postoperative mean mitral valve area is $2.10+0.28cm^2$. We conclude that mitral reconstruction is a predictable and stable operation.

  • Between November, 1984, and May, 1986, 93 patients underwent combined valvular and coronary artery operation. They were 70 male and 23 female, the age ranging from 29 to 82. From this population 89 patients underwent single valve replacement and 4 patients underwent double valve replacement. Patients with mitral valve disease were in the majority present in the age group between 50 till 70, where as in the group after 60 years, patients with aortic valve disease were dominant. The main indication for aortic valve replacement was aortic stenosis and the indication for mitral valve replacement was equal between mitral stenosis and mitral incompetence, the later was due to papillary dysfunction after myocardial infarction. Dyspnea was a very frequent symptom and it was found in nearly all patients. 28 patients had a previous myocardial infarction and severe left ventricular dysfunction. The grafts were placed prior to valve replacement and periods of myocardial ischemia were kept at a minimum by maintaining coronary perfusion throughout the operation. It is our opinion that simultaneous valve replacement and myocardial revascularization does not increase the risk of cardiac valve replacement substantially.

  • 배경: 건삭보존 승모판 치환술이 승모판 폐쇄부전증에 있어서는 좌심실 기능의 개선 및 술후 합병증을 줄일 수 있다고 알려져 있으나 승모판 협착증에 있어서는 좌심실 유출로의 폐쇄나 기계판엽의 운동장애 없이 적당한 크기의 기계판막을 삽입할 수 없다는 점등으로 아직 논란의 대상이 되고 있다. 대상 및 방법: 본원에서는 5명의 승모판 협착증환자와 7명의 승모판 폐쇄부전증 환자를 대상으로, 융합된 교련의 절개, 두꺼워진 판첨을 얇게 박리하고, 전판첨을 전판륜으로부터 2 mm 정도에 절개를 가하고 전판첨 중앙부를 절제하여 판엽을 두 개의 분절로 분리하여 교련부에 재 부착함으로써 건삭 및 판첨을 판륜에 위치이동 하면서 승모판막 치환술을 시행하여 건삭 및 판륜의 연속성을 유지하였다. 결과: 술후 기계판엽의 운동장애나 판막주위누출, 좌심실 유출로의 폐쇄 등 합병증 및 수술 사망환자는 없었다. 결론: 결론적으로 건삭보존 승모판 치환술이 승모판 협착증에 있어서도 안전하고 효과적인 수술방법이라 할 수 있다

  • The results of the clinical observations on the 76 cases of the mitral valvular heart disease treated in the Department of Thoracic and Cardiovascular Surgery, Chung-nam National University Hospital during the period of 3 years from June, 1983 to July, 1986, are as follows: l. Of 76 cases, 43 were male and 33 were female with sex ratio of 1.3:1. 2. The age of the patient varied widely from 12 years of the youngest to 60 years of the oldest. 3. The main clinical symptoms on admission were dyspnea on exertion[100%], palpitation[42%], generalized weakness[29%], indigestion[18%], hemoptysis[16%]. 4. The preoperative functional levels according to NYHA classification were class II, III, IV in 9%, 63%, 28% respectively. 5. All 76 patients were operated on under direct vision using extracorporeal circulation, open mitral commissurotomy was done in 15 cases, mitral valve replacement in 37 cases, mitral valve replacement and aortic valve replacement in 11 cases, mitral valve replacement and tricuspid annuloplasty in 8 cases. 6. The operative mortality was 11.8% and results of the operation were good and excellent in 65 cases of survivors.
