Fourty-five cases of operation were performed for the correction of tricuspid regurgitation [TR] in Pusan National University Hospital between 1982 and 1991.The mean age of the patients was 32.6 years and female was dominant[M:F=1:2.2].Isolated tricuspid regurgitation was rare and 43 patients underwent concomitant other valvular operation including mitral valve replacement. Functional cause was in 39 cases and organic lesions were found in 6 cases. Operative methods were Kay annuloplasty[29], De Vega annuloplasty[12], and tricuspid valve replacement[4]. Ring annuloplasty was not performed. Operative mortality rate was 11.1%[5/45] and late mortality rate was 6.7%[2/30]. The tricuspid valve surgery itself was not a serious risk factor for hospital death and no heart block nor thrombosis was complicated. By echocardiogram early[within 30 days] and late [mean:4.9years] changes of postoperative TR were evaluated. De Vega annuloplasty seemed to bring better late result than Kay annuloplasty[p<0.05]. In four patients with late severe TR,previously replaced tissue valve degeneration[2], pulmonary hypertension[1] and rheumatic TR[1] were the possible causes. This experience suggests that De Vega annuloplasty can be a reliable method in the majority of patients with moderate-to-severe functional TR.

좌심실 판막질환에 동반한 삼첨판패쇄부전증은 주 병소에 따른 2차적 병소로 생각되어 왔다. 그러나 좌심실 주 병소의 성공적인 수술 이후에도 삼첨판패쇄부전증이 호전되지 않고, 심기능 부전의 원인이 된다는 보고가 있다. 현재까지 좌심실 판막질환에 2차적으로 발생한 삼첨판패쇄부전증의 경과를 예측할 수 있는 인자는 확립되어 있지 않으며, 수술 적응증 또한 명확하게 확립되어 있지 않다. 저자들은 폐동맥압과 좌심실구출률, 삼첨판륜성형술이 삼첨판패쇄부전증의 경과에 미치는 영향을 확인하고, 좌심실 판막질환의 수술 시 동반한 삼첨판패쇄부전증의 정확한 수술 적응증을 확립하기 위하여 본 연구를 시행하였다. 대상 및 방법: 저자들은 삼첨판패쇄부전증을 동반한 좌심실 판막질환으로 수술을 받았던 환자들 중 1년 이상 심초음파 검사로 추적 검사를 시행하였던 114명 환자의 의무기록을 조사하였다. 모든 증례는 심초음파 소견으로 삼첨판패쇄부전증 정도, 폐동맥압, 좌심실구출률을 구하였으며, 각 결과를 수술 전과 최종 추적관찰 값을 비교하였다. 결과: 총 114예의 환자중 삼첨판륜성형술을 시행하였던 43예에서는 삼첨판패쇄부전증의 정도가 호전된 경우가 42예(97.7%)였으나, 삼첨판패쇄부전증에 대한 시술을 시행하지 않았던 71명의 환자에서는 호전이 29예(41%), 변화없음이 32예(45%), 악화가 10예(14%)로 두 군 간에 통계적인 차이를 보여주고 있었다(p<0.05). 삼첨판패쇄부전증에 대한 수술을 하지 않았던 군에서 삼첨판패쇄부전증이 악화된 환자들과 악화되지 않았던 환자들간의 폐동맥압과 좌심실구출률의 차이는 없었다. 폐동맥압과 좌심실구출률의 수술 전후변화량은 삼첨판패쇄부전증의 호전도와 상관관계를 확인할 수 없었다. 결론: 폐동맥고혈압과 좌심실구출률로 좌심실 판막질환과 동반된 삼첨판패쇄부전증의 경과를 예측하는 것은 불가능한 것으로 생각하며, 삼첨판륜성형술을 시행한 경우 삼첨판패쇄부전증이 통계적으로 유의하게 감소됨을 확인할 수 있었다. 그러므로 좌심실 판막질환으로 수술을 시행하는 경우, 삼첨판패쇄부전증이 발견되면 그정도와 상관없이 적극적으로 삼첨판륜성형술을 시행하는 것이 장기적으로 중증의 삼첨판패쇄부전증을 예방하는 효과적인 방법이라고 생각한다.

Purpose: This study aimed to analyze changes in QRS duration and cardiothoracic ratio (CTR) following pulmonary valve replacement (PVR) in patients with tetralogy of Fallot (TOF). Methods: Children and adolescents who had previously undergone total repair for TOF (n=67; median age, 16 years) who required elective PVR for pulmonary regurgitation and/or right ventricular out tract obstruction were included in this study. The QRS duration and CTR were measured pre- and postoperatively and postoperative changes were evaluated. Results: Following PVR, the CTR significantly decreased (pre-PVR $57.2%{\pm}6.2%$, post-PVR $53.8%{\pm}5.5%$, P=0.002). The postoperative QRS duration showed a tendency to decrease (pre-PVR $162.7{\pm}26.4$ msec, post-PVR $156.4{\pm}24.4$ msec, P=0.124). QRS duration was greater than 180 msec in 6 patients prior to PVR. Of these, 5 patients showed a decrease in QRS duration following PVR; QRS duration was less than 180 msec in 2 patients, and QRS duration remained greater than 180 msec in 3 patients, including 2 patients with diffuse postoperative right ventricular outflow tract hypokinesis. Six patients had coexisting arrhythmias before PVR; 2 patients, atrial tachycardia; 3 patients, premature ventricular contraction; and 1 patient, premature atrial contraction. None of the patients presented with arrhythmia following PVR. Conclusion: The CTR and QRS duration reduced following PVR. However, QRS duration may not decrease below 180 msec after PVR, particularly in patients with right ventricular outflow tract hypokinesis. The CTR and ECG may provide additional clinical information on changes in right ventricular volume and/or pressure in these patients.

The development of extracardiac valved conduits for establishment of RV-PA continuity has permitted repair of previously uncorrectable congenital heart anomalies and has facilitated the repair of other complex lesions. But the distressing problem of neointimal peel formation with eventual conduit obstruction in patients with Dacron valved conduits has led to the need for premature replacement in many patients. Therefore in the absence of pulmonary hypertension, hypoplastic pulmonary arteries, significant right ventricular dysfunction or unrepaired tricuspid regurgitation, preference of a valveless conduit to a valved conduit gives excellent results and may diminish the need for late reoperation. In our Hanyang University Hospital, the Rastelli operation was performed for the repair of pulmonary atresia with a valveless Gore-Tex conduit. The patient was operated on with good result. The CVP after operation was 8-13 mmHg at POD #0 and 4-6 mmHg from POD #3-4. Postoperatively the patient was acyanotic and had improved physical capacity compared with his preoperative status.

The partial A-V canal defect consist of ostium primum type atrial septal defect with a cleft mitral anterior leaflet. The clinical findings depend upon the site and size of the left-to-right shunt, the degree of A-V valvular regurgitation, and the degree of resultant pulmonary artery hypertension. We experienced 3 cases of similar condition. The data were as follow: 1. Chest P-A showed increased pulmonary vascularity and moderate cardiomegaly with left atrial enlargement. 2. E.K.G. showed left axis deviation, left atrial enlargement, and left ventricular hypertrophy. 3. Right heart catheterization showed significant 02 step up of SVC-RA and left-to-right shunt. 4. Left ventriculogram showed mitral regurgitation and filling of both atrium. Operative findings were as follow: 1. Primum type atrial septal defect [2x2 cm]. 2. Cleft in the anterior leaflet of the mitral vave. 3. No evidence of ventricular septal defect and tricuspid anomaly. Through a right atriotomy with moderate hypothermia, the mitral cleft was approximated with interrupted sutures. The interatrial communication was closed by a patch of Dacron/pericardium. The patch was attached to junction of the mitral and tricuspid valves along the crest of the ventricular septum using interrupted sutures and the other site using continuous sutures. Postoperative course was uneventful and discharged in good general condition except postoperative bleeding in case 3.

Coarctation of aorta is rather common congenital cardiovascular disease in the western contries, but it is known to be less than 2 % in Korea. From June 1986 to December 1992, seven patients of surgically treated coarctation of aorta who were less than 2 years old, were experienced at Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. The patients included six male and one female, with ages in the range of one month and 24 months. Four patients were preductal type and three juxtaductal. Associated cardiac anomalies were present in all patients and they were PDA[6 cases], ASD[3], VSD[2], bicuspid aortic valve[2], aortic stenosis[1], mitral regurgitation[1], and tricuspid regurgitation[1]. The operative procedures were four end to end anastomosis and three subclavian flap aortoplasty. Mean aortic cross clamping times were 37.3 minutes in patients with end to end anastomosis and 30.3 minutes in patients with subclavian flap aortoplasty. There were two operative deaths in patients who were treated with subclavian flap aortoplasty and pulmonary artery banding. One patient who had been treated with subclavian flap aortoplasty was complicated with postoperative mild paraplegia in lower limb. Pulmonary artery banding has been disappointing in our patients, and the data was suggestive that earlier total repair of complicated coarctation might improve survival.

Despite developments in surgical techniques and other interventions, right ventricular (RV) failure remains an important clinical problem in several congenital heart diseases (CHD). RV function is one of the most important predictors of mortality and morbidity in patients with CHD. RV failure is a progressive disorder that begins with myocardial injury or stress, neurohormonal activation, cytokine activation, altered gene expression, and ventricular remodeling. Pressure-overload RV failure caused by RV outflow tract obstruction after total correction of tetralogy of Fallot, pulmonary stenosis, atrial switch operation for transposition of the great arteries, congenitally corrected transposition of the great arteries, and systemic RV failure after the Fontan operation. Volume-overload RV failure may be caused by atrial septal defect, pulmonary regurgitation, or tricuspid regurgitation. Although the measurement of RV function is difficult because of many reasons, the right ventricle can be evaluated using both imaging and functional modalities. In clinical practice, echocardiography is the primary mode for the evaluation of RV structure and function. Cardiac magnetic resonance imaging is increasingly used for evaluating RV structure and function. A comprehensive evaluation of RV function may lead to early and optimal management of RV failure in patients with CHD.

Reduction mammaplasty is the gold standard treatment for gigantomastia. We report one female patient with juvenile gigantomastia associated with severe pulmonary hypertension where her pulmonary pressure decreased significantly after the surgery, improving her quality of life. A 22-year-old female patient with gigantomastia since 10 years old, tricuspid regurgitation, and pulmonary thromboembolism antecedent was admitted to the emergency department. Her oxygen saturation was 89%. Acute heart failure management was initiated. An echocardiogram reported left ventricle ejection fraction (LVEF) of 70% with severe right heart dilation, contractile dysfunction, and arterial pulmonary pressure (PASP) of 110 mm Hg. A multidisciplinary team considered gigantomastia could generate a restrictive pattern, so a Thorek reduction mammoplasty with Wise pattern was performed. Presurgical measurements were: sternal notch to nipple-areola complex, right 59 cm, left 56 cm. Three days after surgery, the patient could breathe without oxygen support. In the outpatient follow-up, patient referred reduction of her respiratory symptoms and marked improvement in her quality of life. Six months after surgery, a control echocardiogram showed a LVEF of 62% and PASP of 85 mm Hg. Pulmonary hypertension may be present in patients with gigantomastia. Reduction mammoplasty may be a feasible alternative to improve the cardiac signs and symptoms in patients with medical refractory management.
