For years, physicians and anatomists have been interested in the heart that has one functioning ventricle. Various terms have been suggested for this entity including single ventricle, common ventricle, double-inlet left ventricle, cor biatriatum triloculare, and primitive ventricle. In this report, the term "single ventricle" is utilized as suggested by Van Praagh, and is defined as that congenital cardiac anomaly in which a common or separate atrioventricular valves open into a ventricular chamber from which both great arterial trunks emerge. An outlet chamber, or infundibulum, may or may not be present and give rise to the origin of either of the great arteries. This definition excludes the entity of mitral and tricuspid atresia. An 11 year old cyanotic boy was admitted chief complaints of exertional dyspnea and frequent upper respiratory infection since 2 weeks after birth. He was diagnosed as inoperable cyanotic congenital heart disease, and remained without any corrective treatment up to his age of 11 year when he suffered from aggravation of symptoms and signs of congestive heart failure for 2 months before this admission. On 22nd of May 1979, he was admitted for total corrective operation under the impression of tricuspid atresia suggested by a pediatrician. Physical check revealed deep cyanosis with finger and toe clubbing, and grade V systolic ejection murmur with single second heart sound was audible at the left 3rd intercostal space. Development was moderate in height [135 cm] and weight[28Kg]. Routine lab findings were normal except increased hemoglobin [21.1gm%], hematocrit [64 %], and left axis deviation with left ventricular hypertrophy on EKG. Cardiac catheterization and angiography revealed 1-transposition of aorta, pulmonic valvular stenosis, double inlet of a single ventricle with d-loop, and normal atriovisceral relationship [Type III C solitus according to the classification of Van Praagh]. At operation, longitudinal incision at the outflow tract of right ventricle in between the right coronary artery and its branch [LAD from RCA] revealed high far anterior aortic valve which had fibrous continuity with mitral annulus, and pulmonic valve was stenotic up to 4 mm in diameter positioned posterolaterally to the aorta. Ventricular septum was totally defective, and one markedly hypertrophied moderator band originated from crista supraventricularis was connected down to the imaginary septum of the ventricular cavity as a pseudoseptum of the ventricle. Size of the defect was 3X3 cm2 in total. Patch closure of the defect with a Teflon felt of 3.5 x 4 cm2 was done with interrupted multiple sutures after cut off of the moderator band, which was resutured to the artificial septum after reconstruction of the ventricular septum. Pulmonic valvotomy was done from 4 mm to 11 mm in diameter thru another pulmonary arteriotomy incision, and right ventriculotomy wound was closed reconstructing the right ventricular outflow tract with pericardial autograft of 3 x 4 cm2. Atrial septal defect of 2 cm in diameter was closed with 3-0 Erdeck suture, and atrial wall was sutured also when rectal temperature reached from 24`C to 35.5`C. Complete A-V block was managed with temporary external pacemaker with a pacing rate of 110/min. thru myocardial wire, and arterial blood pressure of 80/50 mmHg was maintained with Isuprel or Dopamine dripping under the CVP of 25-cm saline. Consciousness was recovered one hour after the operation when his blood pressure reached 100 /70 mmHg, but vital signs were not stable, and bleeding from the pericardial drainage and complete anuria were persisted until his heart could not capture the pacemaker impulse, and patient died of low output syndrome 320 min after the operation.

A 59-year-old man presented for possible durable ventricular assist device (VAD) implantation. He had previously been diagnosed with congenitally corrected transposition of the great arteries, a ventricular septal defect, an atrial septal defect, pulmonary valve stenosis, and aortic valve regurgitation. In the previous 22 years, he had undergone palliative cardiac surgery 3 times. VAD implantation as a bridge to transplantation was planned. Owing to severe adhesions, mesocardia, a left ascending aorta, and moderate aortic regurgitation, we performed VAD implantation and aortic valve closure via a dual left thoracotomy and partial sternotomy.
Understanding of the surgical anatomy of patients with double outlet right ventricle (DORV) is important in the planning of biventricular repair From May 1995 to September 1996, 7 patients underwent biventricular repair for DORV with remote ventricular septal defect. There were 5 males and 2 (tamales. Age at operation varied from 2 to 9 years(mean 3.4$\pm$ 2.7years). Preoperative diagnostic assessment was made by two-dimensional echocardiography and cardiac catheterization. Ventricular septal defect was perimembranous inlet type in all patients. Associated cardiac anomalies were pulmonary atresia in two, pulmonary stenosis in five and tricuspid chordal attachment to zonal septum in five. The operations were performed intraventricular repair and pulmonary enlargement in two, REV operation in two, and Rastelli operation in three. There was no early postoperative deaths and complications. The follow-up period war from 1 month to 18mon1hs, averaging 10: 6.1 months. In the past, we considered the Fontal operation indicative as primary choice when DORV was associated with abnormal tricuspid chordal attachment to the zonal septum, but now we believe that biventricular repair is feasible for those cases by making conal flap or reattachment method. Biventricular repair has theoretic advantages because it estabilishes normal anatomy and physiology, and it was concluded that the precise preoperative evaluation using both echocardiography and cardiac catheterization was essential to the successful surgery.
Background: Simple ventricular septal defect(VSD) is the most common congenital heart disease. Although closure of VSD is currently associated with a relatively low risk, experience with younger and smaller infants has been variably less satisfactory. We assessed the results of surgical closure of VSD in infant. Materials and Methods: Between 1996 and 2000, 45 non-restrictive VSD patients underwent patch repair and retrospective analysis was done. Patients were divided into two groups based on weight: group I infants weighed 5kg or less(n=16), and group II infants weighed more than 5kg(n=29). Both groups had similar variation in sex, VSD location, aortic cross clamp time and total bypass time. But combined diseases (ASD, PDA, MR) were more in group I. We closed VSD with patch and used simple continuous suture method in all patients. Results: There were no operative mortality, no reoperation for hemodynamically significant residual shunt and no surgically induced complete heart block. As a complication, pneumonia(group I: 2 cases, group II: 2 cases), transient seizure(group II: 2), wound infection(group I: 1, group II: 1), urinary tract infection(group I: 1) and chylopericardium(group I: 1) developed, and there was no significant difference between two groups(p>0.05). Conclusion: Early primary closure with simple continuous suture method was applicable in all patients with non-restrictive VSD without any serious complications.

Infective endocarditis is a life-threatening disease, although it is relatively uncommon. Substantial morbidity and mortality result from this infection. Therefore, primary prevention of endocarditis whenever possible is very important. The American Heart Association updated recommendations for the prevention of infective endocarditis in individuals at risk for this disease in 1997. But, utilization of antibiotic prophylaxis for patients at risk does not provide absolute immunity from infection. This report presents the case of infective endocarditis that occurred in spite of appropriate antibiotic prophylaxis in the ventricular septal defect(VSD) patient.
Purpose : The major cause of cardiac dysfunction, after open heart surgery for congenital heart disease, is perioperative myocardial injury. Cardiac troponin I is found only within the myocardial cell, so it can be used as a biochemical marker of the myocardial injury. We performed this study to evaluate the worth of cardiac troponin I as a biochemical marker reflecting the extent of perioperative myocardial injury and recovery. Methods : Thirty-four patients who had undergone elective open heart surgery of congenital heart disease(CHD) from April to July 2001 were enrolled in this study. We measured types of CHD, serial cardiac troponin I(baseline 1 day before operation, postoperative day 1, 2, 3, 7), duration of cardiopulmonary bypass(CPB), aortic cross clamping(ACC), intubation and postoperative hospital stay. Results : Compared with the baseline before operation, there was a significant, increase of cardiac troponin I on the postoperative day 1 and a significant gradual decrease on the day 2, 3, 7. The levels of cardiac troponin I were the highest in the transposition of great artery(TGA) repair on the postoperative day 1 and high in the tetralogy of Fallot(TOF), atioventricular septal defect (AVSD), ventricular septal defect(VSD) and atrial septal defect(ASD) repair with decreasing sequence. The longer duration of CPB, ACC and intubation, the higher of cardiac troponin I, but there were no significant correlations between cardiac troponin I levels and duration of hospital stay. Conclusion : Because there was significant increases or decreases of cardiac troponin I according to the perioperative time and types of the congenital heart disease, it is a worthy biochemical marker which reflects the extent of perioperative myocardial injury and recovery after open heart surgery.
We operated on 199 patients of VSD from 1976 to April l986. Among them, patients of VSD whose medical records were available were analyzed clinically. Operation on patients of VSD occupied 23.9% of total open heart surgery [832 cases] during those days. Of the 164 patients, 93 patients were male [56.7%]. 71 patients were female [43.3%]. Their age ranged from 6 months to 28 years and the mean age was 9.5 year and 82.2% of the patients were between 2 and 15 year of age. Of the patients, body weight below 10Kg were 19 cases. The most common complaints were frequent URI and DOE. On Kirklin`s anatomical classification, type II defect was most common [60.1%], type I [38.4%], combined type I+II, type III, combined type II+Ill and combined type II+IV in orders. Associated anomaly was found in 66 patients [42.5%>]. Pulmonary stenosis was most commonly associated cardiac anomaly [8.4%] and aortic insufficiency [7.1%], ASD, Lt. SVC and PDA in orders. There were extracardiac anomalies such as polydactyly, cleft palate, hypospadia and congenital aniridia, etc. Relationship between ventricular hypertrophy and defect size and cardiac cath. data was analyzed. The overall mortality was 7.0% [14 cases] and complication rate was 22.5% [35 cases].
From February 1988 to December 1990, 42 patients underwent so called REV operation for pulmonary stenosis or atresia with or without anomalies of ventriculoarterial connection and truncus arteriosus. The principles of operative technique are mobilization of pulmonary arterial tree beyond the pericardial reflection, transection of pulmonary trunk between the pulmonary ventricle and pulmonary artery, suture of distal pulmonary arterial stump to the upper margin of Pulmonary ventriculotomy site with absorbable suture, and anterior patch with 0.625% glutaraldehyde fixed autologous pericardium with monocusp inside it. Age at operation ranged 3-156months [mean 41.8 month] with twelve of whom infants. Operative indications were pulmonary atresia, with ventricular septal defect[16], and pulmonary stenosis with double outlet right ventricle[8], with ventricular septal defect[16], with double outlet right ventricle[8], with complete transposition of the great arteries[8], with corrected transposition of the great arteries[6], with Fallot`s tetralogy[3], and truncus arteriosus[1]. There were six hospital deaths[14%] and no late death. Twenty-four of 36 survivals were followed up more than 12 months with good clinical results. Postoperative angiocardiogram was performed in fifteen patients. Hemodynamically, two patents had residual pressure gradients along the pulmonary outflow tract, one patient showed severe pulmonary regurgitation; morphologically, there were six significant stenosis of left pulmonary arterial tree, two of whom showed significant pressure gradients. Our present experience with REV operation suggests that this technique make it possible to perform anatomic repair in a wide variety of congenital anomalies of abnormal ventriculoarterial connection associated with pulmonary outflow tract obstruction without using the prosthetic material, even in infants, with relatively low mortality and morbidity.
This is a case report of surgically treated rupture of Valsalva Sinus aneurysm combined with VSD. He has been relatively healthy until about one month before admission, when during bath, he felt abruptly palpitation, left chest pain and exertional dyspnea. These symptoms have progressed. On admission, thrill was palpable and continuous machinery murmur was audible on 2nd and 3rd intercostal space along the left sternal border. A rupture of Valsalva`s sinus aneurysm was confirmed by aortography and echocardiography but a small VSD was found by cardiotomy in open heart surgery. On 11th Sep. 1978, open heart surgery was performed. Valsalva`s sinus aneurysm came out from right coronary aortic sinus and ruptured into the right ventricle. It sized 1.2X1.5X1.5 cm. Ruptured opening was noted on apex of aneurysm [0.8X0.8cm], VSD [1. 0X0. 3cm in size] was just below the aortic annulus. The aneurysmal sac was removed on neck. After that, VSD and aneurysmal orifice were closed together with interrupted mattress sutures on same plane. The postoperative course was uneventful and discharged three weeks after open heart surgery.
