Prognostic value of the preoperative neutrophil-lymphocyte ratio in patients undergoing the bidirectional Glenn procedure.

Introduction: The neutrophil-lymphocyte ratio (NLR) has been associated with worse outcomes in patients undergoing coronary artery bypass graft surgery. Little is known about this association in the pediatric population who require surgery for congenital heart defects, especially in patients with a single ventricle (SV).

Objective: To analyze the association of the preoperative NLR with outcomes in patients undergoing the bidirectional Glenn procedure.

Single Ventricle Palliation in a Developing Sub-Saharan African Country: What Should be Improved?

Introduction: Single ventricle physiology management is challenging, especially in low-income countries.

Objective: To report the palliation outcomes of single ventricle patients in a developing African country.

Methods: We retrospectively studied 83 consecutive patients subjected to single ventricle palliation in a single center between March 2011 and December 2017.

Clinical profile, management and outcomes of patients with pulmonary embolism: a retrospective tertiary centre study in Angola.

Objective: Pulmonary embolism (PE) is a potentially fatal disease. In Angola, few data are available on its occurrence. The aim of the study was to characterise the clinical profile, management and outcomes of patients with PE.

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.

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.
