Article Abstract
Objective: To investigate the early and midterm postoperative outcomes and analyze risk factors of coronary artery bypass grafting (CABG) in octogenarians.
Methods: Clinical data of 38 patients aged 80 years or greater receiving isolated coronary artery bypass grafting from September 2001 to November 2010 were reviewed. There were 33 male and 5 female patients, aging from 80 to 87 years with a mean of (82.6 ± 1.2) years. Twelve patients underwent conventional (on-pump) CABG and 26 patients underwent off-pump CABG. The number of bypass grafts was 1 to 5 (mean 2.5 ± 1.1). Left internal mammary artery was used in 37 (97.3%) patients.
Results: The perioperative mortality was 2.6% (1/38). Postoperative complications included stroke (4 cases), respiratory infection (1 case). The atrial arrhythmias occurred in 25 patients. Intensive care unit and hospital length of stay lasted (3.8 ± 1.4) days and (15 ± 6) days, respectively. Totally 38 patients were followed up for 4 to 70 months. Six patients died during the follow-up period. The 92.6% patients recovered without any cardiac events.
Conclusions: Isolated CABG can be performed safely with acceptable postoperative morbidity and mortality in octogenarians. Appropriate surgical strategy and intensive perioperative treatment must be enhanced in octogenarians who underwent CABG.

Background: Rare genetic variation provided by whole genome sequence datasets has been relatively less explored for its contributions to human traits. Meta-analysis of sequencing data offers advantages by integrating larger sample sizes from diverse cohorts, thereby increasing the likelihood of discovering novel insights into complex traits. Furthermore, emerging methods in genome-wide rare variant association testing further improve power and interpretability.

Background: Patients with acute coronary syndrome requiring coronary artery bypass graft surgery while on ticagrelor face a high risk of perioperative bleeding because of its strong antiplatelet effect. The Cytosorb® haemoadsorbent membrane (CytoSorbents Corporation, Princeton, NJ, USA), which is CE marked for ticagrelor removal, may help to mitigate this risk.
Aim: To evaluate the cost-revenue impact of the use of Cytosorb® membrane over two different time periods in a high-volume French hospital.

Rationale And Objectives: The prognostic implications of myocardial perfusion imaging (MPI) are imperative to provide proper management of coronary artery disease (CAD). This study aimed to quantify the long-term prognostic value of MPI under routine clinical conditions.
Materials And Methods: This single-center retrospective cohort study evaluated all-cause mortality and cause-specific survival according to MPI findings in patients with suspected or known CAD who underwent diagnostic evaluation or assessment of myocardial ischemia and viability in a tertiary referral cardiovascular center.

Background: Umbilical arterial catheterisation is a common intervention performed in the neonatal intensive care unit (NICU) especially in extremely preterm and extremely low birth weight neonates. Rarely catheter fracture or breakage can occur, leaving behind part of the catheter in the aorta. A handful of cases have been reported in the literature, with the majority being managed surgically.

The outcome of percutaneous coronary intervention (PCI) compared to coronary artery bypass grafting (CABG) is still controversial for patients with left main coronary artery (LMCA) disease. This multicenter cohort study aimed to evaluate the clinical outcomes of LMCA disease patients who underwent PCI or CABG. We reviewed 875 consecutive patients diagnosed with LMCA disease between January 2009 and December 2020 who underwent coronary revascularization by PCI (n = 404) or CABG (n = 471).
