A New Technique for De Novo Tricuspid Valve Construction Using Autologous Pericardium.

Treatment of tricuspid valve endocarditis remains an unsolved problem. When the native valve is unsalvageable, implanting a prosthetic valve becomes a problem of its own. This is a case of de novo tricuspid valve construction using autologous pericardium after prosthetic tricuspid valve reinfection.

Enhanced Recovery After Cardiac Surgery: A Propensity-Matched Analysis.

Enhanced Recovery After Surgery (ERAS) pathways have improved clinical outcomes, cost-effectiveness, and patient satisfaction across multiple non-cardiac surgical specialties. Since the adaptation of ERAS in cardiac surgery is rapidly increasing yet still evolving, herein, we demonstrate early results of our implementation of ERAS cardiac guidelines. We retrospectively reviewed all patients who were managed with our institutional ERAS Cardiac Surgery guidelines between 5/2018 and 6/2019(N = 102). Postoperative primary outcomes (total ventilation times(hours), intensive-care unit(ICU) stay, and postoperative hospital length of stay (LOS)) were compared to 1:1 propensity matched controls from the pre ERAS era between January 2017 and March 2019. A total of 76 propensity-matched pairs were identified. Compared to the matched controls, ERAS patients had significantly shorter median ventilation times(3.5 vs. 5.3 hours, p = .01), ICU stays(median 28 vs 48 hours, p=.005) and postoperative hospital LOS (median 5 vs. 6 days, p = .03). There were no operative mortalities and no significant differences in 30-day readmission rates. There were also no significant differences in post-operative stroke, acute kidney injury, atrial fibrillation, and reoperation rates for bleeding. Two-year survival was also not statistically different between the two cohorts (p = .22). Our initial experience with implementation of ERAS protocols in cardiac surgery appear to demonstrate that these protocols are associated with shorter ventilation times, ICU stay, and hospital LOS without compromising patient outcomes. While these results are promising yet preliminary, further studies are warranted to demonstrate whether ERAS algorithms in cardiac surgery can consistently expedite postoperative recovery and improve outcomes.

Postoperative Outcomes in Infants Undergoing ABO-incompatible Heart Transplantation in the United States.

BACKGROUND: ABO-incompatible heart transplant is a method to increase the infant donor pool. However data on long-term survival and rejection after ABO-incompatible heart transplant in recent era are limited. METHODS: The United Network for Organ Sharing database was queried for infant heart transplants performed from January 2008 to March 2020. Patient demographics and known risk factors for posttransplant mortality were collected. Statistical analysis using Bayesian additive regression trees was performed to evaluate the association of ABO incompatibility and overall survival, graft survival, acute rejection episodes, and length of stay. RESULTS: Of 1368 included infants (age < 1 year), 280 (20.47%) were ABO incompatible. ABO incompatibility was not associated with increased all-cause mortality, acute rejection episodes, or length of stay, whereas extracorporeal membrane oxygenation and intubation status of the recipient at the time of transplantation were associated with increased all-cause mortality and graft failure. Idiopathic cardiomyopathy was associated with a decreased likelihood of posttransplant all-cause mortality. One-, 5-, and 10-year survival rates among compatible vs incompatible transplants were estimated to be 90% vs 88%, 82% vs 79%, and 77% vs 73%, respectively. CONCLUSIONS: ABO-incompatible infant heart transplant does not affect posttransplant survival, incidence of rejection, or postoperative length of stay. Therefore it remains a viable and important strategy to increase the infant donor pool.

Left Atrial Appendage Epicardial Clip (AtriClip): Essentials and Post-Procedure Management.

Left atrial appendage exclusion is a viable alternative to anticoagulation for stroke risk reduction in atrial fibrillation patients. In this article we address the essentials and post-procedural management of left atrial appendage exclusion using the AtriClip.

Combined Tracheal Resection and Coronary Artery Bypass With ECMO Support.

In patients with critical tracheal stenosis, extracorporeal membrane oxygenation support provides an additional level of safety over conventional approaches to secure an airway. This brings operations with exquisite complexity into the realm of routine feasibility. Here we describe a case of combined tracheal resection with 4-vessel coronary artery bypass grafting in a patient with critical tracheal stenosis, occluded coronary arteries, and severely reduced ejection fraction. Postoperatively, the patient made an excellent recovery. This case exemplifies a trend where multidisciplinary cooperation, refinements in surgical techniques, and technological advances allow ever more complex cardiothoracic operations to be performed safely.

Totally Thoracoscopic Closure of the Left Atrial Appendage.

The left atrial appendage (LAA) is a major site of clot formation in atrial fibrillation. Stand-alone thoracoscopic LAA complete closure can decrease stroke risk and may be an alternative to life-long oral anticoagulation. This report describes a technique for totally thoracoscopic LAA exclusion with an epicardial clip device. This approach provides a safe and likely more effective alternative to LAA management than other endocardial devices.
