3D Digital and Printed Hearts from Different Canine Breeds as an Educational Tool for Radiographic Interpretation.

Three-dimensional (3D) printing is a new method of creating anatomical models, which can enhance the training of students and health professionals. The large breed-variation in dogs means that interpretation of thoracic radiographs can be challenging for the inexperienced radiologist. The aim of this study was to develop digital and printed 3D cardiac models from six canine breeds and evaluate their use as a tool for studying breed variations in radiology.

Difference Between Cardiopulmonary Bypass Time and Aortic Cross-Clamping Time as a Predictor of Complications After Coronary Artery Bypass Grafting.

Introduction: Along with cardiopulmonary bypass time, aortic cross-clamping time is directly related to the risk of complications after heart surgery. The influence of the time difference between cardiopulmonary bypass and cross-clamping times (TDC-C) remains poorly understood.

Objective: To assess the impact of cardiopulmonary bypass time in relation to cross-clamping time on immediate results after coronary artery bypass grafting in the Registro Paulista de Cirurgia Cardiovascular (REPLICCAR) II.

Extubation in the Operating Room After Coronary Artery Bypass Graft Surgery Reduces Hospital Stay.

Design: A retrospective cohort analysis.

Setting: Ten cardiac referral hospitals in Latin America; participants of the São Paulo Registry of Cardiovascular Surgery II (REPLICCAR II).

Methods: Cross-sectional cohort study in the São Paulo Registry of Cardiovascular Surgery II (REPLICCAR II).

Transit-time flow measurement parameters after protamine infusion in CABG surgeries.

Objective: The objective of this study is to evaluate protamine sulfate effects on graft's blood flow by comparing transit-time flow measurement (TTFM) values before and after protamine administration.

Methods: This is an observational study with data collected between years 2018 and 2020. Immediate graft patency was evaluated using TTFM.

Performance of a novel risk model for deep sternal wound infection after coronary artery bypass grafting.

Clinical prediction models for deep sternal wound infections (DSWI) after coronary artery bypass graft (CABG) surgery exist, although they have a poor impact in external validation studies. We developed and validated a new predictive model for 30-day DSWI after CABG (REPINF) and compared it with the Society of Thoracic Surgeons model (STS). The REPINF model was created through a multicenter cohort of adults undergoing CABG surgery (REPLICCAR II Study) database, using least absolute shrinkage and selection operator (LASSO) logistic regression, internally and externally validated comparing discrimination, calibration in-the-large (CL), net reclassification improvement (NRI) and integrated discrimination improvement (IDI), trained between the new model and the STS PredDeep, a validated model for DSWI after cardiac surgery.

Adherence to the cardiac surgery checklist decreased mortality at a teaching hospital: A retrospective cohort study.

Objective: To evaluate the impact of adherence to the cardiac surgical checklist on mortality at the teaching hospital.

Methods: A retrospective cohort study after the implementation of the cardiac surgical safety checklist in a reference hospital in Latin America. All patients undergoing coronary artery bypass surgery and/or heart valve surgery from 2013 to 2019 were analyzed.

in Non-Cystic Fibrosis Bronchiectasis: Prevalence and Genomic Basis of High Inoculum β-Lactam Resistance.

The pathobiology of in non-cystic fibrosis bronchiectasis (nCFB) is poorly defined. When present at high density or "inoculum," some methicillin-sensitive (MSSA) can inefficiently degrade antistaphylococcal β-lactam antibiotics via BlaZ penicillinases (termed the "inoculum effect" [IE]). Given the high burden of organisms in bronchiectatic airways, this is particularly relevant.

Isolated Pulmonary Emergomycosis in an Immunocompetent Patient in Alberta, Canada.

pulmonary infection was incidentally diagnosed in an asymptomatic patient suspected to have metastatic osteosarcoma. Molecular diagnosis was imperative to fungal identification given overlapping histopathological features with histoplasmosis. This report documents a case of isolated pulmonary emergomycosis in an otherwise immunocompetent patient while discussing diagnostic and management pitfalls of this emerging and underdiagnosed infection.

Mortality risk prediction in high-risk patients undergoing coronary artery bypass grafting: Are traditional risk scores accurate?

Background: The performance of traditional scores is significantly limited to predict mortality in high-risk cardiac surgery. The aim of this study was to compare the performance of STS, ESII and HiriSCORE models in predicting mortality in high-risk patients undergoing CABG.

Methods: Cross-sectional analysis in the international prospective database of high-risk patients: HiriSCORE project.

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.

Platelet Reactivity in Patients With Acute Coronary Syndromes Awaiting Surgical Revascularization.

Background: Dual antiplatelet therapy is recommended for patients with acute coronary syndromes (ACS). Approximately 10% to 15% of these patients will undergo coronary artery bypass graft (CABG) surgery for index events, and current guidelines recommend stopping clopidogrel at least 5 days before CABG. This waiting time has clinical and economic implications.

Pericardial-Peritoneal Window as an Alternative Treatment for Large and Recurrent Pericardial Effusion Post-Pericardiotomy.

Introduction: The presence of mild to moderate pericardial effusion after cardiac surgery is common and oral medical therapy is usually able to treat it. Larger effusions are less frequent and surgical intervention is usually necessary. However, there are some rare cases of large effusions that are recurrent even after intervention and become challenging to treat.

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.

Anemia in Cardiac Surgery - Can Something Bad Get Worse?

Introduction: Anemia and blood transfusion are risk factors for morbidity/mortality in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). The objective of this study is to analyze the association of blood transfusion with morbidity/ mortality in patients undergoing coronary artery bypass grafting (CABG) under CPB in the state of São Paulo, Brazil.

Methods: This is a retrospective analysis using the State of São Paulo Registry of Cardiovascular Surgery from November 2013 to August 2014.

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.
