Conduction disturbances following surgical aortic valve replacement with a rapid-deployment bioprosthesis.
The implantation of rapid-deployment aortic valves may interfere with the conduction system of the heart. This study evaluates the occurrence and predictive factors of conduction anomalies in patients undergoing surgical aortic valve replacement (SAVR) with a rapid-deployment balloon-expandable bioprosthesis in a single-center, real-world experience. ⋯ The PPI rate was in the range of previous reports for rapid-deployment prostheses. PPI did not have a significant influence on short- to intermediate-term survival. Case selection with exclusion of patients presenting with baseline conduction disturbances may decrease the rate of new PPIs after SAVR with rapid-deployment balloon-expandable bioprostheses.

Historical ArticleThe Thoracic Surgery Residents Association: Past contributions, current efforts, and future directions.
The Thoracic Surgery Residents Association (TSRA) is a resident-led organization established in 1997 under the guidance of the Thoracic Surgery Directors Association to represent the interests and educational needs of cardiothoracic surgery residents. We aim to describe the past contributions, current efforts, and future directions of the TSRA within a conceptual framework of the TSRA mission. ⋯ The TSRA continues to be the leading cardiothoracic surgery resident organization in North America, providing educational resources and networking opportunities for all trainees. Future directions include development of an integrated disease-based resource and continued collaboration within and beyond our specialty to enhance the educational opportunities and career development of cardiothoracic trainees.

Preoperative nutrition-enhanced recovery after surgery protocol for thoracic neoplasms.
Because patients' preoperative nutritional status influences the outcomes, we have used a preoperative nutrition program for surgical patients for a 2-year period and compared the results with those from a cohort treated in the previous 2 years. ⋯ Thoracic surgeons should consider using the nontoxic, patient-compliant N-ERAS protocol for their patients, with an expectation of improved clinical results at lower hospital costs-an important consideration when exploring methods to decrease costs because hospitals are increasingly being paid by a negotiated prospective bundled payment reimbursement model.

Autologous mitochondrial transplantation for cardiogenic shock in pediatric patients following ischemia-reperfusion injury.
To report outcomes in a pilot study of autologous mitochondrial transplantation (MT) in pediatric patients requiring postcardiotomy extracorporeal membrane oxygenation (ECMO) for severe refractory cardiogenic shock after ischemia-reperfusion injury (IRI). ⋯ Twenty-four patients were included (MT, n = 10; Control, n = 14). Markers of systemic inflammatory response and organ function measured 1 day before and 7 days following revascularization did not differ between groups. Successful separation from ECMO-defined as freedom from ECMO reinstitution within 1 week after initial separation-was possible for 8 patients in the MT group (80%) and 4 in the Control group (29%) (P = .02). Median circumferential strain immediately following IRI but before therapy was not significantly different between groups. Immediately following separation from ECMO, ventricular strain was significantly better in the MT group (-23.0%; range, -20.0% to -28.8%) compared with the Control group (-16.8%; range, -13.0% to -18.4%) (P = .03). Median time to functional recovery after revascularization was significantly shorter in the MT group (2 days vs 9 days; P = .02). Cardiovascular events were lower in the MT group (20% vs 79%; P < .01). Cox regression analysis showed higher composite estimated risk of cardiovascular events in the Control group (hazard ratio, 4.6; 95% confidence interval, 1.0 to 20.9; P = .04) CONCLUSIONS: In this pilot study, MT was associated with successful separation from ECMO and enhanced ventricular strain in patients requiring postcardiotomy ECMO for severe refractory cardiogenic shock after IRI.
