Taking the pulse of brain death: A meta-analysis of the natural history of brain death with somatic support.

Background And Purpose: The conceptualization of brain death (BD) was pivotal in the shaping of judicial and medical practices. Nonetheless, media reports of alleged recovery from BD reinforced the criticism that this construct is a self-fulfilling prophecy (by treatment withdrawal or organ donation). We meta-analyzed the natural history of BD when somatic support (SS) is maintained.

Diabetes Mellitus is an Independent Predictor of Spinal Cord Injury After Descending Thoracic and Thoracoabdominal Aneurysm Repair: Maximum Likelihood Conditional Regression in a Propensity-Score Matched Cohort.

Objective: To discern the impact of diabetes mellitus (DM) on spinal cord injury (SCI) after open descending thoracic and thoracoabdominal aneurysm repair (DTAAAR).

Background: Compared with euglycemia, hyperglycemia, and ketosis make neurons respectively more vulnerable and more resilient to ischemia.

Methods: During the study period (1997-2021), patient who underwent DTAAAR were dichotomized according to the presence/absence of DM.

The Incidence and Natural Progression of New-Onset Postoperative Atrial Fibrillation.

Objectives: This study aimed to characterize the natural progression and recurrence of new-onset postoperative atrial fibrillation (POAF) during an intermediate-term follow-up post cardiac surgery by using continuous event monitoring.

Background: New-onset POAF is a common complication after cardiac surgery and is associated with an increased risk for stroke and all-cause mortality. Long-term data on new POAF recurrence and anticoagulation remain sparse.

Splanchnic occlusive disease predicts for spinal cord injury after open descending thoracic and thoracoabdominal aneurysm repair.

Objective: In the present study, we sought to discern the effects of splanchnic occlusive disease (SOD; renal, superior mesenteric, and/or celiac axis arteries) on spinal cord injury (SCI; paraparesis or paraplegia) and major adverse events (MAE) after descending thoracic aneurysm (DTA) and thoracoabdominal aortic aneurysm (TAAA) open repair.

Methods: Patients who had undergone DTA/TAAA repair at our institution were dichotomized according to the presence of SOD, which was investigated as a predictive factor of our primary (SCI) and secondary (operative mortality, myocardial infarction, stroke, tracheostomy, de novo dialysis, MAE, survival) endpoints. Risk adjustment used both propensity score matching and multivariable logistic regression.

Systematic Review - Neuroprotection of ketosis in acute injury of the mammalian central nervous system: A meta-analysis.

To evaluate the neuroprotection exerted by ketosis against acute damage of the mammalian central nervous system (CNS). Search engines were interrogated to identify experimental studies comparing the mitigating effect of ketosis (intervention) versus non-ketosis (control) on acute CNS damage. Primary endpoint was a reduction in mortality.

Effect of Skeletonization of Bilateral Internal Thoracic Arteries on Deep Sternal Wound Infections.

Background: Bilateral internal thoracic arteries (BITA) coronary bypass grafting may improve long-term outcomes but is associated with increased deep sternal wound infections (DSWIs). We analyzed whether BITA skeletonization impacts DSWIs and operative mortality (OM) using The Society of Thoracic Surgeons Adult Cardiac Surgery Database.

Methods: Primary, isolated, nonemergent/nonsalvage BITA patients (July 2017 to December 2018) in The Society of Thoracic Surgeons Adult Cardiac Surgery Database were divided into groups based on BITA harvesting technique: both skeletonized (ssBITA) and ≥1 nonskeletonized (Non-ssBITA).

Single- versus multidose cardioplegia in adult cardiac surgery patients: A meta-analysis.

Objective: To compare outcomes of single (intervention group: del Nido [DN], and histamine-tryptophan-ketoglutarate) versus multidose (control group) cardioplegia in the adult cardiac surgery patients.

Methods: Medical search engines were interrogated to identify relevant randomized controlled trials and propensity-score matched cohorts. Meta-analysis was conducted for primary (in-hospital/30-day mortality) and secondary (ischemic and cardiopulmonary bypass [CPB] times, reperfusion fibrillation, peak of cardiac enzymes, myocardial infarction) endpoints.

Open radial artery harvesting better preserves endothelial function compared to the endoscopic approach.

Objectives: Both the open and endovascular techniques are commonly used for harvesting the radial artery (ORAH and ERAH, respectively), and yet, very little is known about the effects of these 2 techniques on endothelial integrity and function of the radial artery (RA). The aim of this study was to assess the endothelial integrity and function of RA harvested using the 2 approaches.

Methods: Two independent surgical teams working in the same institution routinely use the RA for coronary artery bypass grafting exclusively employing either ORAH or ERAH.

Bilateral internal thoracic artery versus radial artery multi-arterial bypass grafting: a report from the STS database†.

Objectives: Multi-arterial bypass grafting with bilateral internal thoracic (BITA-MABG) or radial (RA-MABG) arteries improves long-term survival, but its increased complexity raises perioperative safety concerns. We compared perioperative outcomes of RA-MABG and BITA-MABG using the Society of Thoracic Surgeons Adult Cardiac Surgery Database (STS-ACSD).

Methods: We analysed the 2004-2015 BITA-MABG and RA-MABG experience in STS-ACSD.

Technical Aspects of the Use of the Radial Artery in Coronary Artery Bypass Surgery.

Background: The radial artery has been used for coronary artery bypass surgery for more than 25 years. The recent confirmation of the clinical benefits associated with the use of the artery is likely to drive a new interest toward this conduit in the next few years.

Methods: A group of surgeons with extensive experience in the systematic use of the radial artery summarize here the key technical aspects of the use of the conduit for coronary bypass operations.

Radial artery versus saphenous vein as the second conduit for coronary artery bypass surgery: A meta-analysis.

Objective: Individual studies may be limited by sample size to detect differences in late survival between radial artery (RA) or saphenous vein graft (SVG) as a second conduit for coronary artery bypass surgery. Here we undertook a meta-analysis of the best evidence available on the comparison of early and late clinical outcomes of the RA and the SVG.

Methods: MEDLINE and EMBASE were searched for studies comparing use of the RA versus SVG for isolated coronary artery bypass surgery.

The Incremental Value of Three or More Arterial Grafts in CABG: The Effect of Native Vessel Disease.

Background: We investigated whether extended arterial grafting with three or more arterial grafts in patients with a left internal thoracic artery to left anterior descending artery graft improves survival in coronary artery bypass graft surgery patients and whether its effects will depend on the extent of coronary artery disease; specifically three-vessel disease (3VD) versus two-vessel disease (2VD).

Methods: Fifteen-year mortality was analyzed in 11,931 patients with multivessel disease and primary isolated left internal thoracic artery to left anterior descending artery coronary artery bypass graft surgery with 2 or more grafts. Patients were aged 64.

The Radial Artery for Percutaneous Coronary Procedures or Surgery?

This article summarizes the current research on the benefits of using the transradial approach for percutaneous procedures and the radial artery as a conduit for coronary artery bypass surgery. Based on the available evidence, the authors provide recommendations for the use of the radial artery in patients undergoing percutaneous or surgical coronary procedures.

Operative Outcomes of Multiple-Arterial Versus Single-Arterial Coronary Bypass Grafting.

Background: More than 90% of coronary artery bypass grafting (CABG) is performed with a single-arterial bypass graft (SABG), based on the left internal thoracic artery (ITA) with supplemental vein grafts. This practice, often justified by safety concerns with multiple-arterial grafting (MABG), defies evidence of improved late survival achieved with bilateral ITA (BITA-MABG) or left ITA plus radial artery (RA-MABG). We hypothesized that MABG and SABG are equally safe.

Incremental Value of Increasing Number of Arterial Grafts: The Effect of Diabetes Mellitus.

Background: Multiarterial coronary grafting with two arterial grafts leads to improved survival compared with conventional single artery based on left internal thoracic artery to left anterior descending artery and saphenous vein grafts. We investigated whether extending arterial grafting to three or more arterial grafts further improves survival, and whether such a benefit is modified by diabetes mellitus.

Methods: We analyzed 15-year coronary artery bypass graft surgery mortality data in 11,931 patients (age 64.

Optimal management of radial artery grafts in CABG: Patient and target vessel selection and anti-spasm therapy.

The current literature on radial artery grafting is reviewed focusing on the optimal deployment of radial artery grafts in coronary artery bypass surgery with specific attention to the selection of patients and target vessels for radial artery grafting.

Worldwide Trends in Multi-arterial Coronary Artery Bypass Grafting Surgery 2004-2014: A Tale of 2 Continents.

Recent evidence shows that multi-arterial coronary artery bypass grafting (MABG) based on bilateral internal thoracic (BITA) or left internal thoracic (LITA) and radial artery (RA) improves long-term outcomes compared with single arterial coronary artery bypass grafting (SABG) (LITA + saphenous vein graft). How this evidence affected the worldwide use of MABG, if at all, is not well defined. Accordingly, we report 10-year temporal trends of MABG utilization from 2 continents.

Mechanisms, Consequences, and Prevention of Coronary Graft Failure.

Graft failure occurs in a sizeable proportion of coronary artery bypass conduits. We herein review relevant current evidence to give an overview of the incidence, pathophysiology, and clinical consequences of this multifactorial phenomenon. Thrombosis, endothelial dysfunction, vasospasm, and oxidative stress are different mechanisms associated with graft failure.

Randomized comparison of the clinical outcome of single versus multiple arterial grafts: the ROMA trial-rationale and study protocol.

Summary: The primary hypothesis of the ROMA trial is that in patients undergoing primary isolated non-emergent coronary artery bypass grafting, the use of 2 or more arterial grafts compared with a single arterial graft (SAG) is associated with a reduction in the composite outcome of death from any cause, any stroke, post-discharge myocardial infarction and/or repeat revascularization.

Unlabelled: The secondary hypothesis is that in these patients, the use of 2 or more arterial grafts compared with a SAG is associated with improved survival. The ROMA trial is a prospective, unblinded, randomized event-driven multicentre trial comprising at least 4300 subjects.

High-frequency percussive ventilation in cardiac surgery patients failing mechanical conventional ventilation.

Objectives: Failure of mechanical conventional ventilation (MCV) after cardiac surgery portends a dismal prognosis, with extracorporeal membrane oxygenation frequently utilized as a salvage therapy. We describe our experience with high-frequency percussive ventilation (HFPV) as a rescue therapy for hypoxaemia refractory to MCV after cardiac surgery.

Methods: In a 6-year retrospective analysis from 2009 to 2015, we identified 16 subjects who required HFPV after cardiac surgery.
