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.

Background: The short-term results after using arterial grafts still raise questions and doubts for medical society.

Objective: To compare the immediate outcomes of patients undergoing single arterial graft versus multiple arterial grafts coronary artery bypass grafting surgery.

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.

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.

A benchmark in the isolated tricuspid valve surgery is necessary.

Advances in surgical techniques, enabling correction of regurgitation, and preserving the tricuspid valve, are also factors that encourage early surgical indication and improve long-term outcomes.

Multivessel Woven Coronary Artery Disease.

Woven coronary disease is a rare pathology with unknown etiology. Although initially considered benign, recent publications report myocardial ischemia caused by the affected vessel. Since most patients are asymptomatic, long-term follow-up to understand its behavior is mandatory.

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.

Evaluation method of training simulation on biological models for cardiovascular surgery residents.

Objectives: The goal of this study was to describe and evaluate our simulation training program on biological models for the cardiovascular surgery residency program at our institution.

Material And Methods: Since 2016, with the purpose to develop better practical performance and evaluate the improvement of resident's surgical skills, a simulation training program was implemented, composed of some elemental procedures in cardiovascular surgery. It was established with one wet lab session weekly lasting 2 h, coached by two expert cardiovascular surgeons.

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.

Bentall-de Bono procedure for acute aortic dissection.

We present a patient with an acute type A aortic dissection that involves the aortic root. The high mortality of patients with this condition is often associated with operations performed by surgeons with minimal experience dealing with aortic diseases. Therefore, less-experienced surgeons often opt for less complicated techniques like supracoronary ascending aortic replacement.

The use of internal mammary vein in coronary artery surgery.

Arterial revascularization, and in particular, left internal mammary artery (LIMA), has shown to improve survival of patients with coronary artery disease. Complete revascularization often requires the use of other grafts and saphenous vein graft is still the most common conduit used. Several other types of grafts have been utilized during revascularization, including the radial artery and gastroepiploic artery.

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.

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.

Validation and quality measurements for STS, EuroSCORE II and a regional risk model in Brazilian patients.

Objectives: The objectives of this study were to describe a novel statewide registry for cardiac surgery in Brazil (REPLICCAR), to compare a regional risk model (SPScore) with EuroSCORE II and STS, and to understand where quality improvement and safety initiatives can be implemented.

Methods: A total of 11 sites in the state of São Paulo, Brazil, formed an online registry platform to capture information on risk factors and outcomes after cardiac surgery procedures for all consecutive patients. EuroSCORE II and STS values were calculated for each patient.

Geometric reconstruction of a left ventricular aneurysm with coronary artery bypass graft.

Left ventricular aneurysm is a late mechanical complication of untreated acute myocardial infarction. It has become relatively rare since the development of percutaneous cardiac intervention.  Most aneurysms are located at the anterior ventricular wall, and are caused by total occlusion of the left anterior descending artery.

Predictive performance of six mortality risk scores and the development of a novel model in a prospective cohort of patients undergoing valve surgery secondary to rheumatic fever.

Background: Mortality prediction after cardiac procedures is an essential tool in clinical decision making. Although rheumatic cardiac disease remains a major cause of heart surgery in the world no previous study validated risk scores in a sample exclusively with this condition.

Objectives: Develop a novel predictive model focused on mortality prediction among patients undergoing cardiac surgery secondary to rheumatic valve conditions.

Off-pump versus On-pump Coronary Artery Bypass Grafting in Frail Patients: Study Protocol for the FRAGILE Multicenter Randomized Controlled Trial.

Introduction: Advances in modern medicine have led to people living longer and healthier lives. Frailty is an emerging concept in medicine yet to be explored as a risk factor in cardiac surgery. When it comes to CABG surgery, randomized controlled clinical trials have primarily focused on low-risk (ROOBY, CORONARY), elevated-risk (GOPCABE) or high-risk patients (BBS), but not on frail patients.
