The frequency of intraventricular conduction disturbance [IVCD] following right ventriculotomy and right atriotomy approach for ventricular septal defect [VSD] closure was compared in various conditions. Of the 170 isolated VSD patients, 114 patients were repaired via right ventriculotomy and 56 patients were repaired via right atriotomy. The results were as follows; 1. The frequency of IVCD was 45.6% in right ventriculotomy, and 21.2% in right atriotomy group [P<0.01]. The frequency of IVCD following transverse ventriculotomy and vertical ventriculotomy was not significantly different. 2. The frequency of IVCD in subarterial VSD following right ventriculotomy and right atriotomy was not significantly different. But the frequency of IVCD in perimembranous VSD was 50.8% in right ventriculotomy and 27.5% in right atriotomy group [P<0.01]. 3. The frequency of IVCD was higher in groups with larger VSD and it was more significant in right ventriculotomy group. 4. The frequency of IVCD was higher in patch graft closure and it was more significant in right ventriculotomy group. 5. Overall frequency of IVCD was lower in right atriotomy than right ventriculotomy group.

We compared postoperative results according to the different surgical approach in 180 cases of isolated ventricular septal defects operated at the department of Thoracic and Cardiovascular Surgery in Kyungpook University Hospital from January 1987 to December 1991. Of the 180 cases, 109 were males and 71 females, age ranging from 6 months to 15 years (mean: 5.6 years) and body weight ranging from 6 to 52㎏(mean : 20㎏). According to Soto's classification, perimembranous types were comprised of 119 cases (66％), doubly committed subarterial type 49 cases(27％), and muscular type 12 cases(7％). Patients were divided into three groups according to the incision methods: right atriotomy group (39％), right ventriculotomy group (47％), and pulmonary arteriotomy group (14％). The mean aortic cross clamp time was shorter in right atriotomy group (39 min.) than right ventriculotomy group (79min.) in the cases of large perimembranous VSD (P＜0.001). Spontanous recovery rate of cardiac rhythm after VSD closure was higher in right atriotomy group (51％) than right ventriculotomy group (32％) in the cases of perimembranous VSD (P＜0.05). The incidence of postoperative RBBB was 17.6％ with no statistical differences between right atriotomy group(17.9％) and right ventriculotomy group(19.2％). Overall mortality rate was 5.6％(10 cases) with no significant differences according to surgical approach.

As OHS is prevalent on whole world, LV-RA shunts once thought as quite rare congenital heart disease are reported frequently. Two cases of LV-RA shunts were operated at N.M.C. in 1983: One of them combined VSD, the other membranous ventricular septal aneurysm protruding into right atrial chamber. In case 1, which was diagnosed correctly, right atriotomy was enough to close the defect under ECC, but in case 2, which was misdiagnosed as ASD preoperatively, atriotomy was added to ventriculotomy. The LV-RA defects were closed by U-shaped direct suture with Teflon felt pledget. Postoperative course was uneventful in both of them.

Cor triatriatum is a relatively rare cardiac anomaly, whose major feature is a fenestrated membrane separating an upper common pulmonary venous chamber from a lower true left atrial cavity. Interatrial communications may be present between the right atrium and the common pulmonary venous chamber or the true left atrium. From April 1981 to April 1992, 24 patients with cor triatriatum were treated at Seoul National University Hospital. Ages ranged from 1 month to 24 years with mean of 7.4 years. Twenty patients had interatrial communications through a patent foramen ovale, primum or secundum defect of the atrial septum. Four had no interatrial communications. Fourteen patients had associated anomalies; partial anomalous pulmonary venous connection in 3, total anomalous pulmonary venous connection in 2, persistent left superior vena cava in 3, and other anomalies in 6 patients. Surgical corrections were performed through right atriotomy in 18 patients, left atriotomy in 4, and both atriotomy in 2. Three patients [12.5%] died early after operation; two of them were associated with single ventricle. Six out of 21 survivors [28.6%] experienced complications; recurrent pneumonia, pulmonary embolism, ischemic encephalopathy, diaphragmatic palsy and tachyarrhythmias. At the time of follow up, all survivors, except one, were in functional class I. Surgical correction of cor triatriatum restored normal hemodynamic status with relatively low operative mortality, especially in patients not complicated with severe anomalies. This report summarizes the clinical diagnosis, associated anomalies, interatrial communications, surgical approach and late result of 24 patients underwent surgical corrections in our hospital.

Left atrial myxoma, an unusual clinical entity, may cause severe and progressive cardiac disease mimicking mitral valvular disease. In recent years, increased clinical awareness and improved diagnostic techniques has led to a higher incidence of correct preoperative diagnosis. Recently we experienced 2 cases of left atrial myxoma, which were removed successfully under the cardiopulmonary by pass. The first case was 45 years old woman and the second was 23 years old female. Preoperative definite diagnosis was entertained by angiocardiography and echocardiography in both cases. In the first case, tumor was removed with left atriotomy and atrial septectomy was done with additional right atriotomy. In the second case, tumor and atrial septum were removed en bloc through the right atrium. Both patients were discharged with good results 2 weeks postoperatively.

Cor triatriatum is a rare congenital heart disease that is often lethal in children if not correctly identified and properly managed, Characteristically an anomalous membrane divides the left atrium into two chambers one located posterosuperiorly which is connected to the common pulmonary venous trunk and the other anteroinferiorly which is connected to the left atrial appendage and the mitral valve. Eight patients with Cor triatriatum were been seen at our hospital from 1984 to 1999. The clinical presentation diagnostic evaluation and surgical results are outlined in this retrospective review. Resection of the obstructing anomalous atrial membrane was performed using a hypothermic cardiopulmonary bypass in all cases. Right atriotomy was performed in all patients and left atriotomy was performed in a patient who had poor preoperative general conditions and serious cardiac defects(TAPVR & hypoplastic left ventricle) died of low cardiac output during the immediate postoperative period. The postoperative course has been excellent in the remaining. Cor triatriatum is amenable to surgical repair with excellent results when diagnosed early and in those who are not complicated by other complex cardiac anomalies.

The intraventricular conduction disturbances have been documented after correction of ventricular septal defects by any surgical route but debated its etiology. And so the frequency of conduction disturbances following right ventriculotomy, right atriotomy and pulmonary arteriotomy for closure of ventricular septal defects was compared in various conditions. The present series consists of 218 patients with ventricular septal defects. They had the surgical repair at the Seoul National University Hospital from January 1983 to October 1984. Conduction disturbances were studied with conventional 12 leads electrocardiogram. Of the 218 VSD`s 139 patients were repaired via vertical right ventriculotomy, 45 patients via right atriotomy, 34 patients via pulmonary arteriotomy. 1] Of 218 patients the frequency of RBBB was 26.1% and the frequency of RBBB + LAH was 6.0%. 2] There is no statistical difference between right ventriculotomy group [30.2%] and right atriotomy group [24.4%]. But there is significant difference between right ventriculotomy group and pulmonary arteriotomy group [11.8%] [P<0.05]. 3] In respect to anatomical classification by Kirklin`s method, the frequency of RBBB was higher in type II [32.1%] than in type I [14.9%]. [P<0.05] But in each anatomical type, there is no influence of the various surgical approach on the incidence of postoperative RBBB. 4] The frequency of RBBB was 31.8% in patch closure group and 14.3% in direct closure group. [P<0.05] Although the result suggests that there is no significant difference in various surgical approaches on the incidence of postoperative conduction disturbances, it may be reduced by a new-ventricular approach or a limited incision at right ventricular outflow tract in right ventricular approach.

Primary cardiac tumors usually are benign and are left atrial myxoma. We experienced with two cases of left atrial myxoma recently, and underwent surgical resection successfully. Diagnoses were obtained by echocardiogram and the angiocardiography was not performed. The operation consisted of excision of the tumor with a segment of atrial septum or wall through a right atriotomy, transseptal approach. Postoperative functional results were good and the literature is reviewed.

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.
