Prediction of Long-Term Survival after Coronary Artery Bypass with Bilateral Internal Thoracic Artery Grafting: External Validation of A Contemporary Nomogram.

Background: This study aimed to verify the external validation of a contemporary nomogram in predicting long-term survival after an isolated coronary artery bypass with bilateral internal thoracic artery grafting (CABG-BITA). Methods: Consecutive patients who underwent CABG-BITA at a single center were included in the study. All the predictors of the original risk score (age, diabetes mellitus, chronic obstructive pulmonary disease, congestive heart failure, chronic renal failure, old myocardial infarction, ejection fraction, intra-aortic balloon pump and peripheral arterial disease) were available for analysis.

Superiority of bilateral internal thoracic artery grafting in long-term survival after coronary artery bypass through the lenses of a bedside risk score.

Objective: Risk algorithms for the prediction of long-term survival after coronary artery bypass grafting (CABG) do not include the use of bilateral internal thoracic artery (BITA) grafting among the independent predictors. We sought to reveal the superiority of BITA grafting in the long-term outcome through the lenses of an existing bedside risk score (BRS).

Methods: This study analyzed data from 5,666 consecutive patients undergoing isolated (n = 4,715 - BITA = 2,792) and combined (n = 951 - BITA = 246) CABG.

EuroSCORE predicts long-term mortality after heart valve surgery.

Background: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) is the most rigorously evaluated scoring system in cardiac surgery. We sought to evaluate the performance of EuroSCORE in the prediction of long-term mortality in patients undergoing heart valve surgery.

Methods: Medical records of patients with isolated or combined heart valve surgery, who were discharged alive (n = 1035), were retrospectively reviewed.

Risk factors for sepsis and endocarditis and long-term survival following coronary artery bypass grafting.

We sought to determine risk factors for sepsis and/or endocarditis (S/E) and to identify their impact on long-term survival after coronary artery bypass grafting (CABG). We studied 3760 consecutive patients who underwent isolated CABG from 1992 to 2002. Patients with CABG without S/E were compared with those who developed S/E.
