  • Congenital supravalvar aortic stenosis is an obstruction caused by localized or diffuse narrowing of the aortic lumen commencing immediately above the aortic valve. We experienced a case of diffuse supravalvar aortic stenosis involving ascending aorta from just above the sinuses of Valsalva to the proximal l cm of the innominate artery. Supravalvar aortic stenosis in this patient, in contrast to the form seen in infants and children, was not associated with mental retardation, peculiar faces or the syndrome of hypercalcemia. Diagnosis was confirmed by retrograde left heart catheterization and left ventriculography. Surgical correction was performed by the replacement of oval shaped Woven Dacron patch over the narrow segment of aorta under the cardiopulmonary bypass. Blood pressure was controlled sufficiently with some adjunct of Inderal postoperatively. The patient was discharged with much improvement.

  • Total 145 cases mitral vlave replacement were performed in Department of Thoracic and Cardiovascular Surgery in Chungnam National University Hospital during the period from May 1983 to July 1991. Sixty-one patients were male and 84 patients were female and the range of age was from 12 to 66 years old with the mean of 37.9[$\pm$11.6] years. Valvular lesions were 49 cases of mitral stenosis, 18 cases of regurgitation and 78 cases of combined lesion. Used valve were Ionescu-Shiley[42 cases], Bjork-Shiley[49 cases], Inact[6 cases], St. Jude Medical[11 cases] and CarboMedics[37 cases]. Mean size of valve was 29.8$\pm$1.68mm. Early morality was 13.8%[20 cases] and low output syndrome was most common cause[9 cases]. Age, functional classification and biventricular hypertrophy were risk factors. All survived cases were followed up without missing. Mean follow up period were 3 years and 3 months. Total 14 cases of death[9.7%] were observed and heart failure, unexplained sudden death and bleeding were the causes in that order. Common late complications were heart failure and bleeding related with anticoagulation. Actuarial survival rate at 5 years was 83$\pm$5.4% in overall, 78$\pm$7.2% in tissue valve group, 87$\pm$6.8% in mechanical valve group. The actuarial freedom rate from thromboembolism at 7 years was 89$\pm$8.3% in overall, 86$\pm$9.9% in tissue valve group and 97$\pm$1.9% in mechanical valve group. Actuarial freedom rate from bleeding at 5 years with anticoagulation was 88.9$\pm$4.2% in overall, 96$\pm$3.9% in tissue valve group, 86$\pm$4.6% in mechanical valve group. Reoperation was done in 3 cases with heart failure with tricuspid regurgitation and thromboembolism in 2 cases. The functional status of survived cases was I or II.

  • The left atrial [LA] dimension and atrial fibrillation [AF] in patients with mitral valvular heart diseases have been thought to be related to hemodynamic burden to the LA depending on severity of stenosis or regurgitation of mitral valve, left ventricular contractility and the heart conditions. If hemodynamic burden persists long, it can affect the LA wall and structural change of the LA wall itself can developed. So the structural change of the LA wall could be thought to be related to the LA dimension and AF. To verify this relation, the LA wall biopsy was performed in 26 patients with rheumatic mitral valvular heart disease at the left atriotomy incision margin which was posterior to the interatrial groove after completion of surgery to the mitral valve such as valve replacement or commissurotomy. Relation of the pathological state of the LA wall to AF and the LA dimension measured by M-mode echocardiography was studied. The conclusions were as follow. 1. There was tendency that degree of fibrosis of myocardium of the LA wall was related to the LA dimension. 2. There was more chance that patients who had severe fibrosis of myocardium of the LA wall had pre and postoperative AF. 3. There was no relation between reduction rate of the LA dimension before and after surgery and degree of fibrosis of myocardium of the LA wall.

  • Evaluation of heart function is of importance in assessing the results of valvular heart surgery. Information on volume and functional change of heart chamber can be obtained by cardiac catheterization and echocardiography. We studied 41 patients with mitral stenosis[MS] and 23 patients with mitral regurgitation[MR] using M-mode echocardiography before and after mitral valve replacement[MVR] at Pusan Paik Hospital. Preoperative cardiac catheterization was available in 56 cases, and the results were obtained as follows. 1. In patients with MS, preoperative average LV end-diastolic dimension[EDD] and end-systolic dimension[ESD] were remained within normal range, but postoperative EDD and ESD were significantly decreased[P<0.01]. The preoperative and postoperative LV ejection fraction[EF] were remained within the normal range and no significant change[P>0.05]. The preoperative left atrial dimension[LAD] was enlarged considerably above normal[P<0.01], but was significantly decreased after surgery[P<0.001]. The preoperative LV posterior wall thickness[PWTh] was within normal range, and no significant change after surgery[P>0.05]. 2. In patients with MR, preoperative average end-diastolic dimension[EDD] and end-systolic dimension[ESD] were significantly greater than normal[P<005], but postoperative EDD and ESD were significantly decreased[P<0.01]. The preoperative LV ejection fraction[EF] and fractional shortening[FS] were within normal range, and no significant change after surgery[P>0.05].The preoperative left atrial dimension[LAD] was enlarged considerably above normal [P<0.01], but was significantly decreased after surgery[P<0.001].The preoperative LV posterior wall thickness[PWTh] was within normal range, and no significant change after surgery[P>0.05].

  • Over the past 4 decades after World War II a great deal of data and clinical experiences have been accumulated relating to the diagnosis and surgical treatment of congenital and acquired cardiovascular diseases in Korea. Clinical data on cardiovascular surgical cases performed in all 22 hospitals for open heart surgery in Korea was collected from it`s starting up to December 1984. The first recorded open heart surgery for a young adult atrial septal defect was performed by Young Kyoon Lee, M.D. on August 7, 1959, Seoul National University Hospital, Korea. And, some scattered reports on cardiovascular surgical cases in it`s early period have changed recently the number of hospitals for open heart surgery and clinical cases enormously in total amount of 13, 100 cardiovascular operations performed on 12, 990 cases up to December 1984. Of the total 13, 100 cardiovascular operations, congenital cardiovascular anomaly occupied 70%. Of the congenital cases, 6, 580 operations for acyanotic group [operative mortality 4.5%], and 2, 489 operations for cyanotic group [operative mortality 20%]. The incidence of congenital cardiovascular anomaly in order of frequency was ventricular septal defect [29%], patent ductus arteriosus [26%], Tetralogy of Fallot [22%], atrial septal defect [8, 6%], pulmonary valve stenosis [3.0%], and endocardial cushion defect [1.1%]. Of the 3, 412 valvular heart disease cases, which occupied 85% of total 4, 031 acquired cardiovascular disease, individual incidence was in mitral 2, 565 [63.5%], double valve 451 [11.1%], and simple aortic valve 351 [8.7%]. Total number of valve replaced, mechanical and tissue, was 2, 795, and 1, 884 for mitral, 808 for aortic, and 103 for tricuspid in position. Operative mortality for prosthetic valve replacement in total was 9.8%. Remained acquired cardiovascular cases chronic constrictive pericarditis [7.9%], cardiac tumor [1.9%], coronary artery bypass [1.8%], cardiac trauma [1.2%] and less than 1% of thoracic aortic aneurysm. Overall operative mortality for open and non-open cardiovascular surgical operation was 7.7% [congenital acyanotic group 3.2%, congenital cyanotic group 19.4%, and acquired group 7.8%]. In conclusion, present status of cardiovascular surgery in Korea is stabilized with accumulation of clinical cases and experiences, and the future in the field of cardiovascular surgery is promising, especially in the infant cardiac surgery and aortocoronary bypass surgery, with abrupt increase of specialized cardiac centers, trained specialists, and expanding social health insurance.

  • Shone complex is a rare congenital disorder that involves 4 obstructive lesions of the left heart, as follows: parachute mitral valve, supravalvular mitral ring, subaortic stenosis, and coarctation of the aorta. Incomplete forms with 2 or 3 of these lesions in adult patients have been rarely reported in the literature, meaning that insufficient general data exist concerning the surgical strategy and clinical follow-up. Herein, we report the case of a 31-year-old woman with a diagnosis of incomplete form of Shone complex with parachute mitral valve and coarctation of the aorta who underwent successful single-stage surgical repair.

  • The half-turned truncal switch (HTTS) operation has been reported as an alternative to the Rastelli or $r{\acute{e}}paration$ $\grave{a}$ $l^{\prime}{\acute{e}}tage$ ventriculaire procedures. HTTS prevents left ventricular outflow tract (LVOT) obstruction in patients with complete transposition of the great arteries (TGA) with a ventricular septal defect (VSD) and pulmonary stenosis (PS), or in those with a Taussig-Bing anomaly with PS. The advantages of the HTTS procedure are avoidance of late LVOT or right ventricular outflow tract (RVOT) obstruction, and of overstretching of the pulmonary artery. We report the case of a patient who underwent HTTS for TGA with VSD and PS, in whom there was no LVOT obstruction and only mild aortic regurgitation and mild RVOT obstruction, including observations at 12-year follow-up. Our experience with long-term follow-up of HTTS supports a solution for late complications after the Rastelli procedure.

  • A 53-year-old man presenting with dyspnea and chest pain was diagnosed with acute myocardial infarction secondary to occlusion of the left circumflex coronary artery. Urgent revascularization by percutaneous stenting was successfully performed. However, the post-echocardiography revealed a ruptured papillary muscle that was causing severe mitral regurgitation and aggravation of congestive heart failure. The patient subsequently underwent mitral valve repair with papillary muscle re-implantation. Postoperative echocardiography showed a competent mitral valve without residual stenosis or regurgitation. The patient was discharged from the hospital with an uneventful recovery and has been doing well on outpatient follow up.

  • Between Jan. 1986 and Aug. 1992. 72 patients underwent Rastelli procedure. There were 43 male and 29 female, aged 46 days to 16 years [mean age, 5.2 years] with 18 patients less than 2 years of age. All patients had complex defect, 27 pulmonary atresia with ventricular septal defect, 18 corrected transposition of great arteries with pulmonary atresia or punmonary stenosis, 10 truncus arteriosus, 10 double outlet right ventricle with pulmonary atresia or stenosis, 7 complete transposition of great artersia with pulmonary atresia or pulmonary stenosis. The types of extracardiac valved conduit used were prosthetic valve[n=47, 24 car-bomedics, 19 Ionescu-Shiley, 4 Bjork-shiley] and hand-made trileaflet valve using pericardium. [n=23, 20 bovine pericardium, Z autologous pericardium, 1 equine pericardium] The mean size of valved cinduit was 5.25mm larger in diameter than the size of main pulmonary artery. [normalized to the patient`s body surface area] There were 17 hospital death[24%] and 4 late deaths[5.6%]. Postoperative complication rate was 38.9%a, none of which was conduit-related. All patients were followed pos-toperatively for 1 to 73 months. [mean 25.8 months] During follow-up period, reoperation was done in 6 patients due to stenosis of valved conduit. Mean interval between intial repair and reoperation was 20.3 months. In our experience, li recently extracardaic valved conduits between right ventricle [or pulmonary ventricle] and pulmonary artery were inserted with increasing frequency in infants less than 2 year, but hospital mortality was decreased, 2] Risk of reoperation due to conduit stenosis is low, so that the effect of graft failure on overall survival is minimized. 3] Nevertheless, because any type of extracardaic valved conduit is not ideal in children, we recommended that Lecompte should be done if cardiac anatomy is permitted.
