From July 1983 to June 1988, twenty six patients underwent mitral valve repair for pure mitral stenosis[21 patient] or for mitral stenosis with a mild degree of regurgitation[5 patient] at Chonbuk National University Hospital. All patients underwent open mitral commissurotomy and 17 patients required to additional procedures for relief of obstructive subvalvular lesion. There was no operative death. The patients were followed from one to sixty months[mean 24. 1Mo.] One late death occurred due to cardiac and renal failure 10 month postoperatively. Of the 25 surviving patients at the time of follow-up, 17 patients[68%] were in NYHA functional class I and 8 patients[32%] were in class II.

Congenitally corrected transposition of great arteries is a rare congenital heart anomaly. We experienced two case of corrected transposition of great arteries, one [S,L,L] and one [I, D,D] associated with patent foramen ovale, ventricular septal defect and pulmonary stenosis. The patent foramen ovales were closed directly under right atriotomy, the ventricular septal defects were closed with Dacron patch under morphological left ventriculotomy and the pulmonary valvular and subvalvular stenosis were corrected under pulmonary arteriotomy. The postoperatively course was uneventful in case I, the permanent pacemaker was implanted in case ll.

Two cases of the discrete membranous subaortic stenosis were experienced at the Department of Thoracic & Cardiovascular Surgery, National Medical Center, Seoul, Korea. Case I was 31 years old male with a history of aortic valve replacement[Ionescu-Shiley, 19mm] at the other hospital in 1980. Heart failure was noticed 6 years later. On cardiac catheterization, pressure gradient between left ventricle 4 aorta was 104 mmHg, but subvalvular aortic stenosis was not detected by preoperative 2-D echo <% left ventriculogram. Above case revealed stenoinsufficiency of the prosthetic valve. Under the diagnosis of the prosthetic valve failure, re-do aortic valve replacement[Bjork-Shiley, 23 mm] was done. During operation, the discrete membranous subaortic stenosis was incidentally found, and it was completely resected. So we thought that above discrete membranous subaortic stenosis was not detected at first operation, and it was progressed during 6 years, and accelerated the degeneration of the prosthetic valve. Case II was 20 years old female. Her complaints were exertional dyspnea, angina, syncope, which were aggravated since 5 years ago. 2-D echo <% left ventriculogram revealed the discrete membranous subaortic stenosis. Pressure gradient was 20 mmHg, but her symptoms were serious. Associated cardiac anomaly was the persistent left superior vena cava without connection with right superior vena cava. Complete excision of the membranous tissue was done. Post-operative pressure gradient between left ventricle & aorta was absent, and her complaints were nearly subsided. Both cases were type I according to the Newfeld classification of the discrete subvalvular aortic stenosis, and complete excision of the membranous tissue was done without myotomy or mymectomy. And short-term follow-up results[Case I:2 years, Case II: 1 ~ years] were good except soft systolic murmur[grade II/VI] at the aortic area in both cases.

In the presence of severe non-calcific mitral regurgitation, a dilated mitral annulus, absence of severe subvalvular chordal thickening, and no major loss of leaflet substance, reconstructive surgery for mitral regurgitation is a reasonable approach. Between March, 1980 to November, 1980, 5 patients underwent mitral annuloplasty using Carpentier Ring for severe mitral regurgitation. All 5 cases were of rheumatic in origin. There were no ruptured chorda tendinae or ruptured papillary muscles except slight thickening of the leaflet. There was no operative or late death. As is Carpentier`s report, in patient with severe mitral regurgitation who meet above criteria, mitral annuloplasty using Carpentier Ring is preferable to valve replacement.

Congenitally corrected transposition of the great arteries is a rare congenital heart anomaly, in isolation, has no hemodynamic consequences. It is usually associated with one or more of a variety of intracardiac lesions, ventricular septal defect, valvular or subvalvular pulmonary stenosis, and deformity of the systemic atrioventricular valve with insufficiency. This report describes a successful two stage operation for congenitally corrected transposition, [SLL] type, with ventricular septal defect, pulmonary atresia, persistent ductus arteriosus, and atrial septal defect. A 9 years old patient underwent modified Blalock-Taussig operation because of severe pulmonary hypoplasia. 2 years later a corrective operation, direct closure of ASD and PDA, VSD closure with Dacron patch, Enlargement of left pulmonary artery with pericardial patch and Relief of ROTO with Rastelli procedure could be successfully performed without complication.

Congenitally corrected transposition of the great arteries is defined as the anomaly of atrioventricular and ventriculoarterial discordance. Although this condition is compatible with longevity, it is usually associated with other congenital cardiac anomalies, which result in a greatly shortened life span. This report describes a 2 years old female patient who had congenitally corrected transposition of the great arteries associated with ASD, VSD and pulmonary stenosis. The ASD was closed directly through the right atriotomy and the VSD was closed using Dacron patch through right ventriculotomy and the pulmonary[valvular, supra and subvalvular] stenosis was repaired with the use of a valved conduit woven Dacron vessel graft between the pulmonary ventricle and the main pulmonary artery.

Concerning the operative technique for the relief of discrete subvalvular aortic stenosis, emphasis by some authors has been placed on the superiority of blunt dissection in the enucleation of the entire, obstructing structure such as membranous or fibrous ring stenosis compared with the conventional resection by sharp dissection technique. Here report a case operated applying the technique of blunt dissection, analogous to endarterectomy, which resulted in good clinical improvement. The technique is such that the tissue causing obstruction is peeled off the ventricular septum along the plane of cleavage using a dissector, starting under the commissure between right and left coronary cusps. As for the origin of stenosis this case imply a possibility of different mechanism of etiology evidenced by that the tissue removed consisted of elastic fibers only.

We report here on a case of performing a redo-operation for a 65-years-old male patient who had prosthetic endocarditis after reconstruction of the fibrous skeleton due to infective endocarditis 8 years earlier. An aortic annular abscess with a 1cm sized subvalvular abscess and mobile mitral valve vegetation with destruction of the fibrous skeleton was shown on the preoperative echocardiography. An emergency operation was performed due to heart failure. Reconstruction of both the aortic and mitral annuli and the fibrous skeleton was done by using two separate bovine pericardial patches and then mechanical valves were implanted. The postoperative echocardiography shows no paravalvular leakage. The patient has been followed up with no symptoms.

Noonan syndrome is characterized by a Turner-like phenotype and a normal karyotype associated with congenital abnormalities, such as short stature, variable mental retardation, hypertelorism, webbed neck, low posterior hair line, skeletal malformation and congenital cardiovascular defect. Two third of Noonan syndrome have cardiac anormalies, half with pulmonary stenosis. We have experienced two cases of pulmonary stenosis associated with other cardiac anomalies in Noonan syndrome. The first 31-year-old male patient had characteristic appearance of Noonan syndrome with severe infundibular pulmonic stenosis and patent foramen ovate. The second 28-year-old male patient had valvular and subvalvular Pulmonary stenosis with typical Noonan\`s face and stature. Pulmonary valvotomy and hypertrophied muscle bundles in the right ventricular cavity were resected in both cases. Patent foramen ovate was closed directly in the first case. Postoperative follow-up examinations revealed no symptoms and successful outcome.

Submitral left ventricular aneurysm (SMLVA) is a rare disease entity that exclusively occurs in the black population. We herewith report on a surgical case of SMLVA in a 68-year-old male who presented with ventricular tachycardia. He underwent surgical repair under standard hypothermic cardiopulmonary bypass. In the state of apical elevation, a vertical ventriculotomy was made directly over the aneurysm, which was located at the posterobasal aspect of the left ventricle. Radiofrequency ablation was performed on the endocardium all around the neck of the aneurysm and then patch endoaneurysmorrhaphy was carried out with particular care not to injure the mitral valve and subvalvular structure. His postoperative recovery was uneventful. There has been no dysfunction of the mitral valve or recurrence of the ventricular tachycardia at 2 years' follow-up.
