Translation and Validation of the Boston Technical Performance Score in a Developing Country.

Introduction: The Technical Performance Score (TPS) was developed and subsequently refined at the Boston Children's Hospital. Our objective was to translate and validate its application in a developing country.

Methods: The score was translated into the Portuguese language and approved by the TPS authors.

Preoperative Neutrophil-Lymphocyte Ratio Can Predict Outcomes for Patients Undergoing Tetralogy of Fallot Repair.

Introduction: Elevated neutrophil-lymphocyte ratio (NLR) has been associated with poorer outcomes in cyanotic patients undergoing single ventricle palliation. Little is known about this biomarker on patients with tetralogy of Fallot (TOF), the most common cyanotic congenital heart disease. Our objective is to study the impact of preoperative NLR on outcomes of TOF patients undergoing total repair.

The arrival of COVID-19 in Brazil and the impact on coronary artery bypass surgery.

Background And Aim Of The Study: This study analyzed the arrival of coronavirus disease 2019 (COVID-19) in Brazil and its impact on coronary artery bypass grafting (CABG) surgery.

Methods: Patients undergoing isolated CABG in six hospitals in Brazil were divided into two periods: pre-COVID-19 (March-May 2019, N = 468) and COVID-19 era (March-May 2020, N = 182). Perioperative data were included on a dedicated REDCap platform.

The role of the neutrophil-lymphocyte ratio for pre-operative risk stratification of acute kidney injury after tetralogy of Fallot repair.

Introduction: Acute kidney injury is a risk factor for chronic kidney disease and mortality after congenital heart surgery under cardiopulmonary bypass. The neutrophil-lymphocyte ratio is an inexpensive and easy to measure biomarker for predicting outcomes in children with congenital heart disease undergoing surgical correction.

Objective: To identify children at high risk of acute kidney injury after tetralogy of Fallot repair using the neutrophil-lymphocyte ratio.

Anomalous aortic origin of the left main coronary artery associated with arterial compression-Case report.

Background: Anomalous aortic origin of coronary artery is a rare finding, with varied presentation and symptomatology. Increasingly recognized by cardiac imaging, when found it raises questions about the appropriate approach and management.

Case Presentation: We present a case of an 11-year-old female who presented with episodes of shortness of breath, angina, and syncope during exercise.

Most deaths in low-risk cardiac surgery could be avoidable.

It is observed that death rates in cardiac surgery has decreased, however, root causes that behave like triggers of potentially avoidable deaths (AD), especially in low-risk patients (less bias) are often unknown and underexplored, Phase of Care Mortality Analysis (POCMA) can be a valuable tool to identify seminal events (SE), providing valuable information where it is possible to make improvements in the quality and safety of future procedures. Our results show that in São Paul State, only one third of AD in low-risk cardiac surgery was related to specific surgical problems. After a revisited analysis, 75% of deaths could have been avoided, which in the pre-operative phase, the SE was related judgment, patient evaluation and preparation.

Coronary Artery Bypass Graft During the COVID-19 Pandemic.

Since the beginning of the coronavirus disease (COVID-19) pandemic, in March 2020, the number of people infected with COVID-19 worldwide increases continuously. Brazil is being followed with great concern in the international media, as it can, very soon, be the epicenter of the pandemic. Initial surgical data suggest that patients who acquire COVID-19 in the perioperative period are prone to a higher morbidity and mortality, however, evidence in cardiac surgery is still scarce.

Atrioventricular Valve Repair in Single Ventricle Physiology: Timing Matters.

Objectives: Atrioventricular valve (AVV) regurgitation in patients with single ventricle (SV) physiology severely impacts prognosis; the appropriate timing for surgical treatment is unknown. We sought to study the results of surgical treatment of AVV regurgitation in SV patients and evaluate risk factors for mortality.

Methods: Medical records of 81 consecutive patients with moderate or severe AAV regurgitation who were submitted to AVV repair or replacement during any stage of univentricular palliation between January 2013 and May 2017 were examined.

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.
