Methods: A large national registry was used to identify 38,597 patients undergoing isolated mitral repair from 2010 to 2019.

Lessons Learned From Extracorporeal Life Support Practice and Outcomes During the COVID-19 Pandemic.

Extracorporeal membrane oxygenation is increasingly being used to support patients with hypoxemic respiratory failure and cardiogenic shock. During the COVID-19 pandemic, consensus guidance recommended extracorporeal life support for patients with COVID-19-related cardiopulmonary disease refractory to optimal conventional therapy, prompting a substantial expansion in the use of this support modality. Extracorporeal membrane oxygenation was particularly integral to the bridging of COVID-19 patients to heart or lung transplantation.

Overview and Clinical Applications of Artificial Intelligence and Machine Learning in Cardiac Anesthesiology.

Artificial intelligence- (AI) and machine learning (ML)-based applications are becoming increasingly pervasive in the healthcare setting. This has in turn challenged clinicians, hospital administrators, and health policymakers to understand such technologies and develop frameworks for safe and sustained clinical implementation. Within cardiac anesthesiology, challenges and opportunities for AI/ML to support patient care are presented by the vast amounts of electronic health data, which are collected rapidly, interpreted, and acted upon within the periprocedural area.

Impact of minimally invasive lung transplantation on early outcomes and analgesia use: A matched cohort study.

Background: Minimally invasive (MI) approaches to lung transplantation (LTx) offer the prospect of faster recovery compared to traditional incisions, however, little data exist describing the impact of surgical technique on early outcomes and analgesia use.

Methods: A prospectively maintained institutional registry identified 170 patients who underwent LTx between January, 2017 and June, 2022. Post-COVID acute respiratory distress syndrome, repeat, and multiorgan transplants were excluded (n = 27) leaving 37 MILTx and 106 traditional LTx patients.

Deep learning for transesophageal echocardiography view classification.

Transesophageal echocardiography (TEE) imaging is a vital tool used in the evaluation of complex cardiac pathology and the management of cardiac surgery patients. A key limitation to the application of deep learning strategies to intraoperative and intraprocedural TEE data is the complexity and unstructured nature of these images. In the present study, we developed a deep learning-based, multi-category TEE view classification model that can be used to add structure to intraoperative and intraprocedural TEE imaging data.

Objective: The influence of socioeconomic disparities on survival after mitral repair is poorly defined. We examined the association between socioeconomic disadvantage and midterm outcomes of repair in Medicare beneficiaries with degenerative mitral regurgitation.

Methods: US Centers for Medicare and Medicaid Services data were used to identify 10,322 patients undergoing isolated first-time repair for degenerative mitral regurgitation between 2012 and 2019.

Left atrial appendage closure during mitral repair in patients without atrial fibrillation.

Objective: Routine left atrial appendage closure during mitral repair in patients without atrial fibrillation (AF) is controversial. We aimed to compare the incidence of stroke after mitral repair in patients without recent AF according to left atrial appendage closure.

Methods: An institutional registry identified 764 consecutive patients without recent AF, endocarditis, prior appendage closure, or stroke undergoing isolated robotic mitral repair between 2005 and 2020.

Bridging with surgically placed microaxial left ventricular assist devices: a high-volume centre experience.

Objectives: The Impella 5.0 and 5.5 have largely superseded non-ambulatory temporary mechanical support devices; yet, clinical outcomes are predominantly limited to small series: this study presents the experience of a high-volume centre.

Isolated Tricuspid Operations: The Society of Thoracic Surgeons Adult Cardiac Surgery Database Analysis.

Background: Population-level data are limited regarding contemporary practice and outcomes of isolated tricuspid operations. We evaluated this using The Society of Thoracic Surgeons Adult Cardiac Surgery Database.

Sex Disparities in Failure to Rescue After Cardiac Surgery in California and New York.

Background: Women have a higher risk of mortality than men after cardiac surgery independent of other risk factors. The reason for this may not be limited to patient-specific variables. Failure to rescue (FTR) patients from death after a postoperative complication is a nationally endorsed quality care metric.

Robotic degenerative mitral repair: Factors associated with intraoperative revision and impact of mild residual regurgitation.

Objectives: National registry data show wide variability in degenerative mitral repair rates and infrequent use of intraoperative repair revision to eliminate residual mitral regurgitation (MR). The consequence of uncorrected mild residual MR is also not clear. We identified factors associated with intraoperative revision of degenerative mitral repair and evaluated long-term effects of intraoperative mild residual MR.
