Use of Quality of Life in Cardiovascular Surgery in Coronary Artery Bypass Grafting: Validation, Reproducibility, and Quality of Life in One Year of Follow-Up.

Background: The objectives of this study are to validate the Quality of Life in Cardiovascular Surgery (QLCS) questionnaire and to observe the evolution of quality of life in the first year of postoperative follow-up of patients who underwent coronary artery bypass grafting (CABG).

Methods: This was a prospective observational study of patients undergoing CABG from July 2016 to June 2017 who survived and answered the QLCS with 1, 6, and 12 months of follow-up. Validation was evaluated for internal consistency by Cronbach's alpha, test-retest reproducibility by correlation coefficient of concordance, and accuracy for interrater reliability by the kappa statistic.

Quality of Life in Cardiovascular Surgery: Elaboration and Initial Internal Validation of a Quality of Life Questionnaire.

Objective: Elaboration and internal validation of the Quality of Life in Cardiovascular Surgery (QLCS) questionnaire adapted to the reality of Brazilian cardiovascular surgery.

Methods: Cross-sectional pilot study of a prospective cohort included in the Documentation and Surgical Registry Center (CEDREC) for internal validation of the QLCS questionnaire. Four hundred forty-five patients submitted to cardiovascular surgery and who answered a QLCS questionnaire 30 days after hospital discharge were included.

Mortality Predictors in the Surgical Treatment of Active Infective Endocarditis.

Introduction: Active infective endocarditis is associated with high morbidity and mortality. Surgery is indicated in high-risk conditions, and the main determinants of mortality in surgical treatment should be evaluated.

Objective: To identify mortality predictors in the surgical treatment of active infective endocarditis in a long-term follow-up.

Long-term Mortality Predictors in Patients with Small Aortic Annulus Undergoing Aortic Valve Replacement with a 19- or 21-mm Bioprosthesis.

Introduction: Replacement of the aortic valve in patients with a small aortic annulus is associated with increased morbidity and mortality. A prosthesis-patient mismatch is one of the main problems associated with failed valves in this patient population.

Objective: To evaluate the long-term mortality predictors in patients with a small aortic annulus undergoing aortic valve replacement with a bioprosthesis.

Effects of skeletonized versus pedicled radial artery on postoperative graft patency and flow.

Background: Radial artery (RA) was the second arterial graft introduced in clinical practice for myocardial revascularization. The skeletonization technique of the left internal thoracic artery (LITA) may actually change the graft's flow capacity with potential advantages. This leads to the assumption that the behavior of the RA, as a coronary graft, is similar to that of the LITA, when skeletonized.

Risk factors for pre, intra, and postoperative hospital mortality in patients undergoing aortic surgery.

Objectives: The primary objective was to identify predictors of hospital mortality in patients undergoing aortic surgery. The secondary objective was to identify factors associated with clinical outcome composed hospital (death, bleeding, neurologic complications or ventricular dysfunction).

Methods: A cross-sectional design with longitudinal component.

Surgery for aortic valve endocarditis: treatment options for aortic abscess.

Background: Patients with infective endocarditis show a large diversity of anatomical presentations, which has been a complicating factor for the surgical treatment of this condition, especially in those who develop abscesses in the aortic ring or intracardiac fistulae. For this reason, surgeons have been developing tactical options to repair it. There is consensus around the fact that the removal of infected tissue promotes radical cleaning, and that the outcome of the treatment has been improved by the manufacture of biological glues which facilitate the closure of abscesses and by the creation of new valve replacements.

Coronary artery bypass grafting using both internal mammary arteries in patients with diabetes mellitus.

Objective: We sought to describe the use of both internal mammary arteries (IMA) in patients with diabetes mellitus (DM) submitted to coronary artery bypass grafting (CABG).

Method: Between January of 1995 to August of 2005, 4.569 patients received isolated CABG in our institution, of these, 1.

Surgical treatment of coarctation of the aorta using trapezoidal aortoplasty.

Objective: Trapezoidal aortoplasty is a technical variant of end-to-end anastomosis, which, based on elements of geometry, aims at increasing the diameter of the aorta at the level of the suture, therefore reducing the occurrence of residual or recurrent pressure gradients in the short and long run.

Methods: After resecting the coarcted area and ductal tissue, 3 trapezoids are confected in each aortic stump, which, when confronted, create a suture line with a sinusoidal aspect (zigzag). Thirty-three patients underwent surgery with this technique, 22 (66.
