A multinational and multidisciplinary approach to treat CHD in paediatric age in Angola: initial experience of a medical-surgical centre for children with heart disease in Angola.

Background: Epidemiological patterns of cardiac disease differ between developed countries and African nations. Despite the collaborative efforts of developed countries, several obstacles hinder the implementation of successful programmes for the management of children with heart disease in Africa. Materials and methods This study is a retrospective analysis of a bi-national two-institution partnership programme for the treatment of children with congenital and acquired heart disease.

Submitral aneurysm in children.

Background: We report a surgical series of submitral aneurysm in children.

Methods: Between March 2011 and December 2015, eight consecutive patients less than 18 years old with submitral aneurysm underwent surgical correction.

Results: Six patients were female, the mean age was 7 ± 3.

A Right Upper Lobe Mass in the Thorax After Modified Blalock-Taussig Shunt.

We report an incidental finding of pseudoaneurysm in a 10-month-old boy with tetralogy of Fallot and Down syndrome who had undergone placement of a modified Blalock-Taussig shunt at age four months. Computed tomography was a determinant exam for better assessment. The lesion was successfully resected with concomitant complete repair of tetralogy of Fallot in a single-stage.

Anomalous Origin of One Pulmonary Artery From the Ascending Aorta: From Diagnosis to Treatment in Angola.

Background: Anomalous origin of one pulmonary artery is a rare congenital heart disease in which one pulmonary artery branch originates from the ascending aorta.

Objective: To describe the experience of a cardiothoracic center in an African country to repair anomalous origin of one pulmonary artery in the context of Portugal-Angola collaboration.

Methods: Between March 2011 and March 2015, four consecutive patients with anomalous origin of pulmonary artery branch underwent surgical correction.

Ebstein's anomaly in children: a single-center study in Angola.

Introduction And Objective: Ebstein's anomaly is a rare complex congenital heart defect of the tricuspid valve. We aimed to describe the frequency, clinical profile, and early and short-term post-operative results in patients under the age of 18 years operated for this anomaly in a tertiary center in Angola.

Methods: A retrospective cross-sectional study was conducted over a period of 37 months.

Pseudoaneurysm inside of a true aneurysm.

Left ventricular pseudoaneurysms and true aneurysms are two possible complications of myocardial infarction. However, while pseudoaneuryms require urgent surgical resection, true aneuryms can often be managed medically, making imperative an accurate diagnosis.The authors describe a case of a delayed rupture of a true aneurysm that was contained and gave rise to a pseudoaneurysm inside of a true aneurysm.

Early graft patency after off-pump and on-pump coronary bypass surgery: a prospective randomized study.

Aims: Uncertainty persists regarding the impact of the off-pump technique on coronary bypass graft patency. The primary objective of this study was to assess coronary artery bypass graft patency in patients randomized to off-pump and on-pump multivessel coronary artery bypass grafting (CABG). Secondary objectives were clinical outcomes and neuropsychological functioning.

Off-pump coronary artery bypass surgery in women.

Objective: Gender is a well-known risk factor for mortality and morbidity after coronary artery bypass grafting and various reasons have been proposed to explain the poorer results observed in women. The study objective was to determine whether female gender was still an operative risk factor with the adoption of off-pump coronary artery bypass surgery.

Methods: Of 2123 consecutive patients who underwent isolated CABG between November 2002 and December 2007, 1966 (92.

Ebstein's anomaly: a case with an unexpected evolution.

Ebstein's anomaly of the tricuspid valve is a rare and complex congenital heart defect. Its etiology is unknown and in the majority of cases it is multifactorial. Mortality in the neonatal period is high.

Congenital medium sternal cleft with partial ectopia cordis repair.

Congenital sternal malformation is a rare anomaly often diagnosed as an asymptomatic condition at birth. The authors report a clinical case of a full-term female neonate with congenital sternal cleft and partial ectopia cordis. Successful surgical repair was accomplished at 6 days of age.

Interrupted aortic arch: an eight-year experience.

Introduction: Interrupted aortic arch (IAA) is a rare congenital heart defect with a high mortality rate in the neonatal period. Surgical correction of associated intracardiac anomalies can be performed in a one-stage (primary) or two-stage approach.

Objectives: Case review of children with IAA operated in our center and to evaluate the surgical outcomes and the occurrence of complications.

Rationale, design and methodology for a Prospective Randomized Study of graft patency in Off-pump and On-pump MultI-vessel coronary artery bypasS Surgery (PROMISS) using multidetector computed tomography.

Background: Off-pump coronary artery bypass grafting has been accused of possibly compromising graft patency. Sixteen slice computed tomography has shown good diagnostic accuracy in the assessment of coronary bypass graft patency when compared with conventional coronary artery angiography and is less invasive. The study hypothesis is that coronary artery bypass grafting (CABG) performed without cardiopulmonary bypass (Off-Pump) has equivalent early graft patency as if performed with cardiopulmonary bypass (On-Pump) and may have reduced complication rate.

Sixteen-slice multidetector computed tomography for graft patency evaluation after coronary artery bypass surgery.

Objective: To investigate the ability of 16-slice multidetector computed tomography (MDCT) to assess coronary artery bypass graft patency and to detect bypass stenosis by comparison with coronary angiography.

Methods: Thirty patients underwent both conventional coronary bypass angiography and retrospective ECG gated 16-slice multidetector computed tomography after surgery using 0.4 seconds rotation time and 1.

Less invasive coronary artery bypass surgery: early results in 1083 patients operated off-pump.

Objective: To analyze the early results of coronary surgery without cardiopulmonary bypass using the EuroSCORE risk model.

Methods: Out of a series of 1104 consecutive patients undergoing CABG during a 20-month period and whose data were prospectively collected, 1083 patients (98.1%) were operated without cardiopulmonary bypass (CPB) and represent the patient population.

Coronary surgery: which method to use?

Objective: To compare 4 methods of myocardial protection in GABG in terms of markers of myocardial ischemia, mortality, morbidity and mid-term results.

Material & Methods: Retrospective study of 241 consecutive patients undergoing isolated > 1 CABG using one of 4 methods: off-pump (OFF, n = 108), cardiopulmonary bypass (CPB) and cardioplegia (CARD, n = 66), CPB and beating heart (BEAT, n = 47), or CPB and ventricular fibrillation (FIBR, n = 20). Mean age was 65.

Coronary surgery in patients with porcelain aorta.

Four patients with unstable angina due to left main or three-vessel disease scheduled for coronary artery bypass grafting were found intra-operatively to have porcelain ascending aorta, defined as massive calcification of the ascending aorta from the aortic valve to the transverse arch, precluding ascending aorta cannulation or clamping. A no-touch operative technique was applied using the two internal mammary arteries in three cases, with complementary Y-grafting when necessary. Three cases underwent off-pump myocardial revascularization.
