  • Isolated anomalous right coronary artery originating from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly that is asymptomatic and discovered incidentally in most cases. ARCAPA is generally not considered a fatal defect in infancy or childhood, although cases of sudden death have been reported. Here, we report a 2-month-old female infant who presented with a prolonged fever that was determined to be caused by rhinovirus infection. Myocardial ischemia of the left ventricular posterior wall was already seen on echocardiography, and ARCAPA was discovered incidentally. The patient underwent successful surgical reimplantation of the right coronary artery to the aortic root to re-establish dual ostial circulation.

  • Pulmonary atresia and ventricular septal defect with major aortopulmonary collateral arteries [abbreviated as PA+VSD+MAPCA in the following] has limited the success of attempts at accurate diagnosis and complete surgical repair. From April 1986 to September 1990, 23 patients with PA+VSD+MAPCA among 96 patients of PA+VSD in Seoul National University Children’s Hospital were encountered. The group comprised 14 male and 9 female patients with ages ranging from 17 days to 177 months [mean 49.6 months]. We operated one stage total repair on good pulmonary artery sized two patients by R.E.V. [Reparation a l’etage ventriculaire] and Rastelli operation respectively. And the 11 patients who had independent MAPCAs and hypoplastic central pulmonary artery were dealt with unifocalization and modified Blalock-Taussig Shunt and followed by second stage repair in 3 patients later. We successfully had managed 7 patients whose MAPCAs could be ligated with modified Blalock-Taussig Shunt and followed by second stage repair in 3 patients with R.E.V or Rastelli operation. Recently, three obstruction after 11 unifocalization procedures made us to try palliative right ventricle-pulmonary artery conduit operation by Gore-Tex vascular graft interposition under cardiopulmonary bypass. And so we managed another 3 patients with these procedures for the purpose of pulmonary artery growth whose central pulmonary artery were severely hypoplastic. We experienced one death after second stage repair whose central pulmonary artery was created by 12mm Gore-Tex vascular graft and was unifocalized.

  • Origin of both great vessels from morphological left ventricle [DOLV] is a rare cardiac anomaly which embryologic possibility has been explained by differential conal development concept and differential canal absorption concept. Recently we had surgical experience of DOLV in 4 month-age infant weighing 5.7Kg. The chief complaints on admission were cyanosis and anoxic spell during severe crying, and right heart catheterization and right ventriculogram were performed but incorrect diagnosis was made. The operative procedures were ligation of patent ductus arteriosus, patch closure of subaortic VSD aligning aorta and pulmonary artery with left ventricle, suture closure of proximal pulmonary artery and valve and the use of extracardiac valved conduit [Carpentier-Edward l4mm] from right ventricle to distal pulmonary artery. Postoperative course was uneventful and discharged in the good condition.

  • Left main bronchus compression occasionally occurs in patients with cardiac disease. A 19-month-old female patient weighing 6.7 kg was admitted for recurrent pneumonia and desaturation. S he had an atrial septal defect (AS D) with a right aortic arch. Her left main bronchus had been compressed between the enlarged right pulmonary artery (RPA) and the descending thoracic aorta for 14 months. We conducted ASD closure and RPA anterior translocation via sternotomy. The left main bronchus compression was relieved despite the medium-term duration of compression.

  • A congenital fistulous communication between the coronary artery and the cardiac chamber or the pulmonary artery is a rare condition, but increasing cases with this anomaly are being recognized with wide spread use of cardiac catheterization and coronary arteriography. Recently we experienced one case of right coronary artery fistula which was associated with atrial septal defect. The patient was a 24 year old female who was admitted because of cardiac murmur, palpitation and dyspnea on exertion after pregnancy. Cardiac catheterization and selective coronary arteriography revealed that a fistulous communication, forming a large aneurysm, was noted from the right coronary artery emptied into the right ventricle. On the operation field, the right coronary artery was curved and markedly dilated from the aorta to the middle segment at acute margin of the right ventricle. The egg-sized aneurysm of dilated right coronary artery was noticed on right ventricle. The aneurysm was incised longitudinally and both the proximal opening and the termination site of the fistula were closed directly with aneurysmectomy. The right atrium was also opened to evaluate the fistulous termination site and repaired only small interatrial septal defect. Postoperative course was uneventful and she was discharged without problems

  • A pulmonary artery sling is a very rare congenital abnormality in which the left pulmonary artery rises from the posterior surface of the right pulmonary artery and then passes between the trachea and the esophagus, causing tracheal compression. It is associated with tracheo-bronchial abnormalities (50%) and cardiovascular abnormalities (30%). It may produce respiratory symptoms through the airway compression of the abnormal left pulmonary artery and congenital abnormalities associated with it. Because most (90%) pulmonary artery sling patients present symptoms during infancy, their condition is often diagnosed in the first year of life. However, a pulmonary artery sling is occasionally found in adults. It is usually asymptomatic and found incidentally. This is a very rare case of an asymptomatic pulmonary artery sling in an adult. A 38-year-old man presented symptoms of mild exertional dyspnea. His spiral computed tomography showed a pulmonary artery sling. He was discharged without specific treatment because his symptoms improved without specific treatment and might not have been associated with a pulmonary artery sling. We report an adult case of an asymptomatic pulmonary artery sling diagnosed via spiral computed tomography, accompanied by a literature review.

  • Congenital coronary fistula is a rare condition, and with widespread use of cardiac catheterization, angiography and selective coronary arteriography are being recognized with increasing frequency. Fistula originating from the right coronary artery are more common than those from the left coronary artery. The fistula empties into the right side of the heart in 90% of the cases with the right ventricle being the most common recipient chamber, followed by the right atrium and the pulmonary artery. We report a case of congenital coronary artery fistula of the right coronary artery to the left ventricle with significant shunt in a 20 - year old female. It was detected by transthoracic and transesophageal echocardiography and confirmed by cardiac catheterization and coronary angiography. The fistula opening was closed with 6-0 Prolene continuously under cardiopulmonary bypass and moderate hypothermia [ 28 oC ]. Postoperative course was uneventful and the patient was discharged without specific problem.

  • Multistage unifocalization and complete repair have been performed for pulmonary atresia ventricular septal defect and major aortopulmonary collateral arteries. We reported a case that divided major aortopulmonary collateral artery was changed into an aneurysm that compressed the left main bronchus. A 1-year-8-month old boy was operated. The Rastelli operation with left pulmonary artery reconstructuion ligation of patent ductus arteriosus and take-down of right Blalock-Taussing shunt was performed on the patient who had pulmonary atreisia ventricular septal defect patent ductus arteriosus and MAPCA at 1 year and 8 months of his age. He previously underwent the unifocalization and right B-T shunt at 9 months of age,. He repeatedly had difficulty in weaning from the mechanical ventilator, After removing the aneurysm from the divided MAPCA that compressed the left main bronchus externally it was possible to wean him from the mechanical ventilator.

  • This study was performed to compare the radiographic and echocardiographic features of cardiovascular changes between small and large dogs with heartworm diseases. Total of 49 dogs from two institutions were included in this study. The dogs were diagnosed with heartworm infestation and underwent thoracic and echocardiography. On thoracic radiographs, vertebral heart scale, reverse D shape, main pulmonary artery dilation, peripheral pulmonary artery dilation, and evidence of right heart failure were evaluated. On echocardiographs, visibility of worms, main pulmonary artery to aortic root (MPA/Ao) ratio, right to left ventricular basal diameter (RVD/LVD) ratio, and pulmonary hypertension were evaluated and analyzed between small and large dogs. The proportion of reverse D shape of the heart and accuracy for right ventricular hypertrophy in small dogs were lower than those of the large dogs. For echocardiographic parameter, the MPA/Ao and RVD/LVD ratio in the small dogs were significantly lower than those of the large dogs. As the results, thoracic radiography have a tendency to underestimate the severity of HWD in small dogs and should be used with echocardiography.
