Background: Given the uncertainty of US health care finances, an understanding of reimbursement trends has become increasingly important in the field of cardiac surgery. We aimed to assess Medicare reimbursement trends for common cardiac surgical procedures from 2000 to 2022.

Methods: Reimbursement data were extracted from the Centers for Medicare and Medicaid Services Physician Fee Schedule Look-Up Tool during the study period for 6 common cardiac operations: aortic valve replacement, mitral valve repair and replacement, tricuspid valve replacement, Bentall procedure, and coronary artery bypass grafting.

Background: Management of total anomalous pulmonary venous connections has been extensively studied to further improve outcomes. Our institution previously reported factors associated with mortality, recurrent obstruction, and reintervention. The study purpose was to revisit the cohort of patients and evaluate factors associated with reintervention, and mortality in early and late follow-up.

Background: Prior efforts to capture the cardiothoracic surgery community rely on survey data with potentially biased or low response rates. Our goal is to better understand our community by assessing the membership directories from The Society of Thoracic Surgeons (STS), American Association for Thoracic Surgery (AATS), European Association for Cardio-Thoracic Surgery (EACTS), and Asian Society for Cardiovascular and Thoracic Surgery (ASCVTS).

Methods: Membership data were obtained from membership directories.

In the era of lifetime management of aortic valve disease, the Ross procedure emerged as an alternative to prosthetic heart valves for young adults; however, more long-term data are warranted. We performed a meta-analysis of reconstructed time-to-event data to compare long-term outcomes between the Ross procedure and mechanical aortic valve replacement (mAVR) in young adults. PubMed/MEDLINE, EMBASE and GoogleScholar were searched for studies comparing Ross procedure with mAVR that reported mortality/survival rates and/or reoperation rates accompanied by at least one Kaplan-Meier curve for any of the outcomes.

Background: Neonates undergoing congenital heart defect repair require optimized nutritional support in the perioperative period. Utilization of a gastrostomy tube is not infrequent, yet optimal timing for placement is ill-defined. The objective of this study was to identify characteristics of patients whose postoperative course included gastrostomy tube placement to facilitate supplemental tube feeding following neonatal repair of congenital heart defects.

Left ventricular aneurysms may be repaired by the linear technique or endoventricular circular patch plasty technique. Choice of technique should be based on the individual patient, including cavity and aneurysm geometry. In this article, we describe the principles underlying decision making with 2 illustrative cases.
