  • Although antenatal diagnostic technique has considerably improved, precise detection and proper management of the neonate with congenital heart disease (CHD) is always a great concern to pediatricians. Congenital cardiac malformations vary from benign to serious conditions such as complete transposition of the great arteries (TGA), critical pulmonary and aortic valvular stenosis/atresia, hypoplastic left heart syndrome (HLHS), obstructed total anomalous pulmonary venous return (TAPVR), which the baby needs immediate diagnosis and management for survival. Unfortunately, these life threatening heart diseases may not have obvious evidence early after birth, most of the clinical and physical findings are nonspecific and vague, which makes the diagnosis difficult. High index of suspicion and astute acumen are essential to decision making. When patent ductus arteriosus (PDA) is opened Widely, many serious malformations may not be noticed easily in the early life, but would progress as severe acidosis/shock/cyanosis or even death as PDA constricts after few hours to days. Ductus dependent congenital cardiac lesions can be divided into the ductus dependent systemic or pulmonary disease, but physiologically quite different from each other and treatment strategy has to be tailored to the clinical status and cardiac malformations. Inevitably early presentation is often regarded as a medical emergency. Differential diagnosis with inborn error metabolic disorders, neonatal sepsis, persistent pulmonary hypertension of the newborn (PPHN) and other pulmonary conditions are necessary. Urgent identification of the newborn at such high risk requires timely referral to a pediatric cardiologist, and timely intervention is the key in reducing mortality and morbidity. This following review deals with the clinical presentations, investigative modalities and approach to management of congenital cardiac malformations presenting in the early life.

  • A rare case of the association of distal aortopulmonary septal defect, aortic origin of the right pulmonary artery, intact ventricular septum, patent ductus arteriosus and interrupted aortic isthmus in a 40-day-old infant is reported. The infant was suffered from two operations with an interval of nine days. At the first operation a 10mm polytetrafluoroethylene prosthesis was inserted instead of the interrupted aortic isthmus and ductus was ligated via the left posterolateral thoracotomy. But the patient could not be weaned from the respirator because of large amount of left-to-right shunt. So the total correction was subsequently performed after an interval of nine days. At the second operation, tunneling of the right pulmonary artery to the main pulmonary artery through the aortopulmonary septal defect was performed using the Dacron patch via a longitudinal transaortic approach and a separate autologous pericardial patch was applied to the longitudinally incised margins of the anterior wall of the ascending aorta. The second postoperative course was relatively uneventful except some respiratory distress and nutritional problems. Now he is at 6 months of age and thrives well without any symptom. Because the success of the surgical repair of this complex anomalies depends upon the accurate diagnosis and meticulous design of each step of procedure prior to operation these problems are also discussed.

  • Malignant hyperthermia has been reported by many authors since Denborough [1960] first described concerning anesthetic death in a family. Malignant hyperthermia is characterized by a hypermetabolic state [tachycardia, tachypnea, hypercarbia, hypoxia, cyanosis, hypotension, high fever and muscle rigidity] and is related to a hereditary defect of skeletal muscle. In susceptible individuals, it is triggered by potent inhalational anesthetics, depolarizing muscle relaxant [Succinylcholine], amide type local anesthetics [prototype lidocaine] and occasionally by stress due to emotional and environmental factors. Unrecognized and untreated malignant hyperthermia is associated with a very high mortality rate. Recently authors have experienced malignant hyperthermia in 5 year old male child who was diagnosed to have patent ductus arteriosus and interatrial septal defect associated with congenital physical deformities such as short stature, hypotrophic muscles and genu valgus deformity of lower extremity, indirect inguinal hernia and Ramphant caries.

  • Seventeen cases of vascular injuries treated in Chungnam National University Hospital during the period from Apr. 1980 to Sep. 1988 were reviewed. Common causes of injuries were stab wound, automobile accidents and iatrogenic injuries. Of the 11 arterial injuries, 3 were femoral artery which was the commonest in frequency, the next was 2 cases of subclavian, common carotid, iliac artery. Of the 10 venous injuries, the subclavian vein and internal jugular vein were common in frequency. The most frequent type of injuries was laceration[13 cases in 21]. Vascular reconstruction was done by lateral suture repair in 8 cases, autogenous vein graft in 2, prosthetic vascular graft in 5, direct anastomosis in 1 case. Simple ligation was done in 5 cases. There was 1 case of visual field defect as a sequelae in right common carotid artery transaction and 1 case of mortality.

  • From April, 1984 to January, 1985, 57 cases of cardiovascular surgeries were performed at Yeung Nam University Hospital consisting 31 cases of open heart surgery and 26 cases of ligating patent ductus arteriosus. Among 31 cases of open heart surgery, all cases are congenital acyanotic heart disease except a case of rheumatic aortic valvular heart diseases taken aortic valve replacement with Bjrk-Shiley 25mm. Only 2 cases of transient hemoglobinuria were complicated. A case of surgical mortality was present died of acute respiratory failure and intractable arrhythmia, which resulting 3.2% of mortality rate.

  • A surgical correction was successfully performed in a adult female who had pulmonary atresia with almost non-confluent pulmonary artery, PDA and ventricular septal defect. Initially as a first stage of corrective surgery isolation of patent ductus arteriosus, ligation of aortopulmonary collaterals and identification of the pathologic anatomy of left pulmonary artery through left posterolateral approach were performed. At the second stage, a week after the initial operation, total correction was done making both pulmonary arteries confluent with albumin coated woven-dacron graft, external valved conduit and closure of large VSD of subarterial and perimembranous type. The PDA was ligated with previously encircled heavy stitch soon after partial bypass was started. Although massive bleeding from anastomotic site of dilated left pulmonary artery to the graft occurred preoperatively, postoperative functional improvement was excellent in terms of disappearance of cyanosis and normal exercise tolerance.

  • 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.

  • The anomaly which the right pulmonary artery originates from the ascending aorta is a rare and usually fatal form of congenital heart disease. This lesion is often associated with a patent ductus arteriosus. Death frequently occurs in early infancy. Anomalous origin of the right pulmonary artery is much more common than anomalous origin of the left pulmonary artery. The anomalous right pulmonary artery usually arise from the posterior aspect of the ascending aorta close to the aortic valve. We report a 1 month-old infant with right pulmonary artery arising from the ascending aorta, which was corrected successfully by direct anastomosis to the main pul onary artery.

  • Aortic valve repair with the use of tailored autologous pericardial extension to the native cusp was performed in one patient with rheumatic aortic valve incompetence. The patient was a 10-year-old girl with Grade II aortic regurgitation and tiny postoperative recannalization of the patent ductus arteriosus. The left aortic coronary cusp appeared to be a little thickened and a cicatrical shortening of the distance between the free edge of the cusp and its annular attachment. A semilunar shaped patch of autologous pericardium, treated with glutaraldehyde solution[6 minutes in 0.6% solution] was sutured along the free edge of the left coronry cusp. Postoperative recovery was uneventful. Echocardiography 8 months later showed Grade I aortic regurgitation. She is now conducting as usual life.
