Patient-physician sex concordance and outcomes in cardiovascular disease: a systematic review.

The sex disparity in outcomes of patients with cardiovascular disease is well-described and has persisted across recent decades. While there have been several proposed mechanisms to explain this disparity, there are limited data on female patient-physician sex concordance and its association with outcomes. The authors review the existing literature on the relationship between patient-physician sex concordance and clinical outcomes in patients with cardiovascular disease, the evidence of a benefit in clinical outcomes with female patient-physician sex concordance, and the possible drivers of such a benefit and highlight directions for future study.

Intraoperative Anemia Mediates Sex Disparity in Operative Mortality After Coronary Artery Bypass Grafting.

Background: Women undergoing coronary artery bypass grafting (CABG) have higher operative mortality than men.

Objectives: The purpose of this study was to evaluate the relationship between intraoperative anemia (nadir intraoperative hematocrit), CABG operative mortality, and sex.

Methods: This was a cohort study of 1,434,225 isolated primary CABG patients (344,357 women) from the Society of Thoracic Surgeons Adult Cardiac Surgery Database (2011-2022).

Research Concepts and Opportunities for Early-Career Investigators in Cardiac Surgery.

Basic, translational or clinic, research is a key component of cardiac surgery. Understanding basic cellular and molecular mechanisms is key to improving patient outcomes, and cardiac surgical procedures must be compared with nonsurgical alternatives. However, guidance for early-career investigators interested in cardiac surgery research is limited.

Distal aortic biomechanics after transcatheter versus surgical aortic valve replacement: a hypothesis generating study.

Background: Biomechanical effects of transcatheter (TAVR) versus surgical (SAVR) aortic valve interventions on the distal aorta have not been studied. This study utilized global circumferential strain (GCS) to assess post-procedural biomechanics changes in the descending aorta after TAVR versus SAVR.

Methods: Patients undergoing TAVR or SAVR for aortic stenosis were included.

Baseline Intraoperative Left Ventricular Diastolic Function Is Associated with Postoperative Atrial Fibrillation after Cardiac Surgery.

Background: Detailed understanding of the association between intraoperative left atrial and left ventricular diastolic function and postoperative atrial fibrillation is lacking. In this post hoc analysis of the Posterior Left Pericardiotomy for the Prevention of Atrial Fibrillation after Cardiac Surgery (PALACS) trial, we aimed to evaluate the association of intraoperative left atrial and left ventricular diastolic function as assessed by transesophageal echocardiography (TEE) with postoperative atrial fibrillation.

Methods: PALACS patients with available intraoperative TEE data (n = 402 of 420; 95.

Postoperative pericardial effusion, pericardiotomy, and atrial fibrillation: An explanatory analysis of the PALACS trial.

Background: In the Posterior left pericardiotomy for the prevention of atrial fibrillation after cardiac surgery (PALACS) trial, posterior pericardiotomy was associated with a significant reduction in postoperative atrial fibrillation (POAF) after cardiac surgery. We aimed to investigate the mechanisms underlying this effect.

Methods: We included PALACS patients with available echocardiographic data (n = 387/420, 92%).

Postoperative atrial fibrillation: from mechanisms to treatment.

Postoperative atrial fibrillation (POAF) is the most common type of secondary atrial fibrillation (AF) and despite progress in prevention and treatment, remains an important clinical problem for patients undergoing a variety of surgical procedures, and in particular cardiac surgery. POAF significantly increases the duration of postoperative hospital stay, hospital costs, and the risk of recurrent AF in the years after surgery; moreover, POAF has been associated with a variety of adverse cardiovascular events (including stroke, heart failure, and mortality), although it is still unclear if this is due to causal relation or simple association. New data have recently emerged on the pathophysiology of POAF, and new preventive and therapeutic strategies have been proposed and tested in randomized trials.

Gender Disparities in Cardiac Surgery Trials: Leadership, Authorship, and Patient Enrollment.

Background: Studies have highlighted the paucity of women-led randomized controlled trials (RCTs) in cardiovascular medicine. Whether this finding also applies to cardiac surgery has not been evaluated. In this study, we evaluate women authorship, leadership, and women enrollment in cardiac surgery RCTs.

Characteristics of Postoperative Atrial Fibrillation and the Effect of Posterior Pericardiotomy.

Background: Postoperative atrial fibrillation (POAF) is a frequent complication of cardiac surgery. However, only a few detailed descriptions of the arrhythmia have been reported. We aim to describe the characteristics, outcomes, and variables associated with POAF and to evaluate how posterior pericardiotomy (PP) affects POAF characteristics.

Evaluation of the quality of COVID-19 guidance documents in anaesthesia using the Appraisal of Guidelines for Research and Evaluation II instrument.

Background: Guidance documents are a valuable resource to clinicians to guide evidenced-based decision making. The quality of guidelines in anaesthesia and across other specialties has been demonstrated to be poor. COVID-19 presented an urgent need for immediate guidance for anaesthetists as frontline clinicians.

Cardiac surgery's long opioid dependency: time to recalibrate pain therapy?

Opioid analgesia is the cornerstone of anaesthetic management during cardiac surgery. However, a subset of patients use opioids persistently after three months of surgery. We discuss a recent meta-analysis and systematic review by Liu and colleagues describing both patient and peri-procedural risk factors that contribute to this phenomenon in the context of chronic pain after cardiac surgery.

Perioperative Management of Direct Oral Anticoagulants in Cardiac Surgery: Practice Recommendations Based on Current Evidence.

An increasing number of patients on systemic oral anticoagulants present for cardiac surgery, and cardiac anesthesiologists should be well-informed on their management in the perioperative period. Direct oral anticoagulants (DOACs), including factor Xa inhibitors and direct thrombin inhibitors, are an attractive alternative to warfarin due to fewer dietary and drug interactions, less frequent monitoring requirements, and an improved patient adherence. Since the approval of DOACs by the Food and Drug Administration in 2010, the number of patients on these medications only has increased.

Transcatheter Mitral Valve Interventions for Mitral Regurgitation: A Review of Mitral Annuloplasty, Valve Replacement, and Chordal Repair Devices.

Significant mitral regurgitation (MR) is the most common valvular disease in the United States in patients older than 75. However, many patients with severe MR are at a high risk for surgical repair due to other significant comorbidities. Over the past decade, many transcatheter mitral valve devices have been studied that address the different mechanisms of MR, but only a few have received a Conformité Européene (CE) mark or United States Food and Drug Administration (FDA) approval.
