Surgical revascularization for premature coronary artery disease in second and third decade of life.

Coronary artery bypass grafting surgery may be needed in children and young adults for significant premature coronary artery occlusive disease. We report a case series of seven patients who underwent surgical revascularization in their second and third decade of life for significant multivessel coronary artery occlusive disease due to unusual causes.

Study of Pulmonary Arterial Pressures and Histopathological Changes in Patients Having Congenital Heart Defects with Left-to-Right Shunt.

Pulmonary arterial hypertension, a common complication in patients with congenital heart defects with left-to-right shunt who present late is one of the principal determinants of the clinical manifestations, the course and the feasibility of surgical repair. The objective is to study the pulmonary arterial pressures and the pulmonary histopathological changes in patients having congenital heart defects with left-to-right shunt. A total of 20 consecutive patients having congenital heart defects with left-to- right shunt who underwent surgical correction were studied.

An alternative technique for rechanneling of sinus venosus atrial septal defect with partial anomalous pulmonary venous connection using autogenous right atrial appendage.

We report a new technique for closure of sinus venosus atrial septal defect with high partial anomalous pulmonary venous connection. This technique consisted of preservation of the atriocaval junction, advancement of the posterior rim of the atrial septal defect anterosuperiorly and enlargement of the superior caval vein using right atrial appendage. We found this to be a convenient technique and recommend it for correction of this anomaly.

Surgical repair of D-TGA with an aortopulmonary window and ventricular septal defects.

D-Transposition of great arteries with an aortopulmonary window is a rare congenital anomaly. We describe a case of D-Transposition of great arteries with an aortopulmonary window and multiple ventricular septal defects in a 5-month boy who underwent successful surgical repair.

Primary arterial switch operation in children presenting late with d-transposition of great arteries and intact ventricular septum. When is it too late for a primary arterial switch operation?

Objective: The surgical management of infants older than 2 weeks with d-transposition of great arteries and intact ventricular septum (IVS) is a matter of debate. Some studies have presented good results of primary arterial switch operation (ASO) in these children. The aim of this study was to assess the surgical outcome of the primary ASO in children with d-transposition of great arteries and IVS presenting beyond 6 weeks of age.

Relationship of internal jugular venous oxygen saturation and perfusion flow rate in children and adults during normothermic and hypothermic cardiopulmonary bypass.

Introduction: This study was designed to elucidate the trends in cerebral venous oxygen saturation in cyanotics and acyanotics undergoing normothermic and hypothermic cardiopulmonary bypass (CPB) and its relationship to perfusion flow rates.

Methods: Five hundred and forty-eight patients (253 cyanotics) undergoing first surgical correction using CPB were included in this prospective study. One hundred and seventy-two patients underwent surgical correction under normothermic CPB (34-36 degrees C) - group I; 142 patients were operated under moderately hypothermic CPB - group II; and 234 patients were operated under deep hypothermic CPB - group III.

Histomorphometric analysis of intrapulmonary vessels in patients undergoing bidirectional Glenn shunt and total cavopulmonary connection.

Objectives: The purposes of this study were to elucidate the histomorphometry of the intrapulmonary arteries in patients undergoing univentricular type of repairs and to identify the histomorphometric characteristics, if any, that may predispose patients to postoperative Fontan failure.

Patients And Methods: Operatively resected wedges of lung tissue from 44 patients undergoing univentricular type of repairs (aged 17 months to 34 years; mean, 83.52 ± 75.

Surgical repair of congenital diaphragmatic eventration in a septugerian lady.

Congenital diaphragmatic eventration in an elderly is a rare anomaly. We describe a case of congenital diaphragmatic eventration causing respiratory insufficiency in a 72 year lady who underwent successful surgical repair.

Salvage one and one-half ventricular repair and resection of Ewing's sarcoma of cardiac origin.

A 4-year-old boy with primary cardiac Ewing's sarcoma presenting with congestive cardiac failure is reported for its rarity. Its surgical importance is highlighted.

An unusual case of dissecting aneurysms involving both coronary sinuses of valsalva.

A 16-year-old boy with a progressive history of dyspnea and palpitations was diagnosed to have rupture of the right and left coronary sinuses on transthoracic echocardiography. The right coronary sinus had ruptured and dissected into the interventricular septum from its base up to the left ventricular apex and all around the lateral wall of the left ventricle up to the base of the papillary muscles. The left coronary sinus was also ruptured, and the rupture was contained by a false aneurysm that dissected into the roof of the left atrium from the aortomitral intervalvular fibrosa.

Stenosis of the main stem of the left coronary artery in a teenager with Takayasu's arteritis.

Coronary arterial involvement is rare in Takayasu's arteritis. We describe successful coronary arterial bypass grafting in a 15 year teenager with Takayasu's arteritis and unstable angina because of stenosis of the main stem of the left coronary artery.

Successful aneurysmectomy of a congenital apical left ventricular aneurysm.

Congenital apical left ventricular aneurysm is a rare clinical entity that is different from congenital left ventricular diverticulum. This aneurysm usually occurs as an isolated anomaly. Its clinical presentation varies, and it is usually diagnosed by exclusion.

Surgical repair of multiple unruptured aneurysms of sinus of Valsalva.

Unruptured aneurysm of sinus of Valsalva (ASV) is a rare congenital anomaly. We describe a case of multiple unruptured ASV involving right and left aortic sinuses causing congestive cardiac failure in a 16-year-old boy who underwent successful surgical repair.

Multi-modality blood conservation strategy in open-heart surgery: an audit.

The objective of this study was to perform an audit of the use of homologous blood and blood products in patients undergoing open-heart surgery by a single surgical team that follows an in-house protocol for blood conservation. The hospital records of 310 consecutive patients (age >15 years) undergoing open-heart surgery over a period of 8 months were retrospectively reviewed to assess the comprehensive blood conservation protocol. Homologous blood and blood product usage during and after surgery, in the intensive care unit and up to hospital discharge was analyzed.

Central pulmonary artery histopathology in patients with cyanotic congenital heart diseases.

Background: This study evaluated the pulmonary arterial (PA) wall histopathology and the risk factors related to histopathology and inadequate pulmonary artery growth in patients with cyanotic congenital heart diseases (CHDs) undergoing primary or second-stage operations after different types of systemic-to-PA shunts with or without pulmonary arterioplasty.

Methods: Operatively excised full-thickness PA tissue from 150 consecutive patients (mean age, 90.8 +/- 62.

Myocardial injury in coronary artery bypass grafting: on-pump versus off-pump comparison by measuring high-sensitivity C-reactive protein, cardiac troponin I, heart-type fatty acid-binding protein, creatine kinase-MB, and myoglobin release.

Objectives: We sought to investigate the release pattern of different cardiac biomarkers (high-sensitivity C-reactive protein, cardiac troponin I, heart-type fatty acid-binding protein, creatine kinase-MB, and myoglobin) and to establish the diagnostic discrimination limits of each marker protein to evaluate perioperative myocardial injury in patients undergoing coronary artery bypass grafting with or without cardiopulmonary bypass.

Methods: Fifty patients were randomly assigned to on-pump or off-pump coronary artery bypass grafting. All cardiac biomarkers were measured in serial venous blood samples drawn before heparinization in both groups and after aortic unclamping at 1, 2, 4, 8, 24, 48, and 72 hours in the on-pump group.
