  • Background: Mitral valve repair rather than replacement for mitral regurgitation (MR) offers a number of well-accepted benefits. However, the surgical results of repair for mitral valve endocarditis remain largely unknown. Material and Method: Fourteen patients who underwent mitral valve repair for MR caused by mitral valve endocarditis from April 1995 through October 2001 were reviewed retrospectively. There were 9 male patients and mean age was 32$\pm$10 years. Four patients had previous embolism and 2 had active infections. The grade of MR were III in 6 patients and IV in 8. Operatively, mitral annuloplasty was performed in 12 patients and various valvuloplasty techniques were applied in all patients. One patient had immediate valve replacement due to residual MR after weaning of cardiopulmonary bypass. Result: There was no early operative death. Early postoperative transthoracic echocardiography revealed no or grade I of MR and no or mild mitral stenosis in 13 patients. After the mean follow-up of 36 months, there was no late death, and no or grade I of MR in 11 patients (84.6%) and no or mild mitral stenosis in 12 patients (92.3%). Reoperation required in one patient (7.1%). The cumulative freedom from recurrent MR and valve-related reoperation at 5 years were 91$\pm$9% and 75$\pm$22%, respectively. Conclusion: This study suggests that mitral valve repair for mitral regurgitation caused by endocarditis offers good early and intermediate survival and functional improvement without reinfection, and it is an attractive alternative to valve replacement in selective patients with bacterial endocariditis.

  • The incidence of congenital aortic valvular stenosis has been known rare, and approximately 3-6% of congenital heart diseases. Recently, we experienced 1 case of congenital aortic valvular stenosis, and which was corrected surgically under extracorporeal circulation successfully. A 11 years old male pt. was admitted to N.M.C. because of dyspnea, dizziness, chest pain and episode of syncope. An auscultation, harsh systolic murmur [Gr. IV/VI] was noted at aortic area and also palpable strong thrill. ECG showed LVH c strain pattern and suspicious LVH finding in simple chest P-A film. In Lt. cardiac catheterization, abrupt pressure change [110mmHg] between LV & Aorta was noted across the aortic valve. And aortic insufficiency was absent, well visualized both coronary arteries and suspicious bicuspid aortic valve in aortography. Valve form was bicuspid, large one was noncoronary cusp and another cusp was Rt. & Lt. coronary cusp which was interpositioned rudimentary commissure. Central aortic orifice was about 5ram in diameter. Valvulotomy was done along the fusioned commissure between noncoronary cusp and Rt. & Lt.coronary cusp, and then short incision was added between Rt. coronary cusp & Lt. coronary cusp. Immediate postoperative course smooth but unknown cardiac arrest was noted in POD second day. Complete recovery was done without sequelae by resuscitation. After operation, clinical symptoms were subsided but systolic murmur [Gr. II/VI] was audible at aortic area, diastolic murmur was absent. ECG showed still remained LVH but much decreased R wave voltage in Lt. precordial leads. Simple chest P-A showed no interval changes compared to preop film. Control Lt. heart catheterization revealed still remained pressure gradient [40ramrig] between LV & Aorta. But much decreased pressure gradient compared to preop pressure gradient [110mmHg].

  • The burden of valvular heart disease (VHD) is increasing with age, and the elderly patients with moderate or severe VHD are notably common. When to operate in asymptomatic patients with VHD remains controversial. The controversy is whether early surgical intervention should be preferred, or a watchful waiting approach should be followed. The beneficial effects of early surgery should be balanced against operative mortality and long-term results. Indications of early surgery in each of the VHD will be discussed in this review on the basis of the latest American and European guidelines.

  • Background: Sutureless aortic valves may enable shorter procedure times, which benefits patients with elevated surgical risk. We describe the outcomes of patients with aortic stenosis who underwent aortic valve replacement (AVR) using the sutureless Perceval aortic bioprosthesis. Methods: Data from a retrospective cohort were obtained from a clinical database. The study enrolled patients with symptomatic severe aortic stenosis who underwent surgical AVR with a sutureless bioprosthesis between August 2015 and December 2020. In total, 113 patients were included (mean age, 75.3±8.4 years; 57.5% women; median Society of Thoracic Surgeons score, 9.7%; mean follow-up period, 51.19±20.6 months). Of these patients, 41 were octogenarians (36.2%) and 3 were nonagenarians (2.6%). Transthoracic echocardiography was employed to assess changes in ejection fraction (EF), left ventricular mass index (LVMI), and mean pressure gradient (MPG). Results: The in-hospital mortality rate was 2.6%, and 13 patients developed new-onset atrial fibrillation. A permanent pacemaker was implanted in 3 patients (2.6%). The median intensive care unit stay was 1 day (interquartile range [IQR], 1-2 days), and the median hospital stay was 12 days (IQR, 9.5-15 days). The overall survival rate at 5 years was 95.9%. LVMI and MPG were reduced postoperatively, while EF increased over the follow-up period. No structural valve deterioration was observed, and no meaningful paravalvular leakage developed during follow-up. Conclusion: The use of a sutureless valve in the aortic position is safe and feasible, even for high-risk elderly patients requiring surgical AVR. LVMI and MPG decreased postoperatively, while EF increased over the follow-up period.

  • BACKGROUND: Assessment of left ventricular (LV) function plays a pivotal role in the management of patients with valvular heart disease, including those caused by rheumatic heart disease. Noninvasive LV pressure-strain loop analysis is emerging as a new echocardiographic method to evaluate global LV systolic function, integrating longitudinal strain by speckle-tracking analysis and noninvasively measured blood pressure to estimate myocardial work. The aim of this study was to characterize global LV myocardial work efficiency in patients with severe rheumatic mitral stenosis (MS) with preserved ejection fraction (EF). METHODS: We retrospectively included adult patients with severe rheumatic MS with preserved EF (> 50%) and sinus rhythm. Healthy individuals without structural heart disease were included as a control group. Global LV myocardial work efficiency was estimated with a proprietary algorithm from speckle-tracking strain analyses, as well as noninvasive blood pressure measurements. RESULTS: A total of 45 individuals with isolated severe rheumatic MS with sinus rhythm and 45 healthy individuals were included. In healthy individuals without structural heart disease, the mean global LV myocardial work efficiency was 96% (standard deviation [SD], 2), Compared with healthy individuals, median global LV myocardial work efficiency was significantly worse in MS patients (89%; SD, 4; p < 0.001) although the LVEF was similar. CONCLUSIONS: Individuals with isolated severe rheumatic MS and preserved EF, had global LV myocardial work efficiencies lower than normal controls.

  • 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.

  • Two stents were placed across the right subclavian vein due to stenosis of the right subclavian vein in a 40-year-old patient with chronic renal failure on hemodialysis. During the follow up period, one of stents migrated into the right ventricle inducing tricuspid valve insufficiency. Percutaneous stent removal had failed and the stent was removed by open heart surgery with Tricuspid valve repair with a good result, and then we report the case.

  • Congenital coronary arteriovenous fistula is relatively uncommon and often associated with additional congenital and acquired heart disease. If coronary arteriovenous fistula is suspected, the diagnosis can be made readily by cardiac catheterization and selective coronary arteriography. Surgical treatment is very satisfactory, with a low mortality and apparent good long term result. Recently, we experienced one case of congenital coronary arteriovenous fistula which was associated with aortic stenosis and regurgitation. The tortuous fistula tract was noted between the left anterior descending coronary artery and the main pulmonary artery. Under the cardiopulmonary bypass, aortic valve replacement[Carbomedics 23mm] and suture closure of the draining orifice of coronary arteriovenous fistula in the main pulmonary artery just above the pulmonary valve were performed, Postoperative hospital course was uneventful and the patient was discharged postoperative 9th day without any problems.

  • A 6-month-old intact male Maltese dog (2.5 kg of body weight) was presented with the primary complaint of heart murmur and exercise intolerance. Diagnostic studies revealed severe pulmonic stenosis. Since the pressure gradient in stenotic pulmonic valve area was higher than 200 mmHg (maximum flow velocity = 7.1 m/s), the dog was underwent balloon valvuloplasty. With this procedure, the peak pulmonic velocity was reduced to 3.0 m/s (PG = 36 mmHg). Periodic re-evaluations performed in monthly interval revealed no further deterioration even after 4 month of procedure. This is the first case report of pulmonic stenosis fixed by non-surgical balloon valvuloplasty in Korea.
