Multicenter Study Clinical TrialTotal aortic arch replacement using a frozen elephant trunk device: Results of a 1-year US multicenter trial.
In this prospective US investigational device exemption trial, we assessed the safety and 1-year clinical outcomes of the Thoraflex Hybrid device (Terumo Aortic) for the frozen elephant trunk technique to repair the ascending aorta, aortic arch, and descending thoracic aorta. ⋯ One-year results with the Thoraflex Hybrid device are acceptable. Long-term data are necessary to assess the durability of these repairs.

Randomized Controlled TrialSurgical Treatment of Tricuspid Valve Regurgitation in Patients Undergoing Left Ventricular Assist Device Implantation: Interim analysis of the TVVAD trial.
Right heart failure remains a serious complication of left ventricular assist device therapy. Many patients presenting for left ventricular assist device implantation have significant tricuspid regurgitation. It remains unknown whether concurrent tricuspid valve surgery reduces postoperative right heart failure. The primary aim was to identify whether concurrent tricuspid valve surgery reduced the incidence of moderate or severe right heart failure within the first 6 months after left ventricular assist device implantation. ⋯ The presence of significant tricuspid regurgitation before left ventricular assist device is associated with a high incidence of right heart failure within the first 6 months after surgery. Tricuspid valve surgery was successful in reducing postimplant tricuspid regurgitation compared with no tricuspid valve surgery but was not associated with a lower incidence of right heart failure.

Multicenter StudySurgical and transcatheter aortic valve replacement for severe aortic stenosis in low-risk elective patients: Analysis of the Aortic Valve Replacement in Elective Patients From the Aortic Valve Multicenter Registry.
Transcatheter aortic valve implantation (TAVI) remains the preferred strategy for high-risk or elderly individuals with aortic valve (AV) stenosis who are not considered to be optimal surgical candidates. Recent evidence suggests that low-risk patients may benefit from TAVI as well. The current study evaluates midterm survival in low-risk patients undergoing elective surgical AV replacement (SAVR) versus TAVI. ⋯ Our data did not demonstrate a survival difference between TAVI and SAVR during the first 2 postprocedure years. After that time, SAVR is associated with improved survival. Extended observations from randomized trials in low-risk patients undergoing elective surgery are warranted to confirm these findings and draw definitive conclusions.

Intraoperative changes and prognostic implications of pulmonary hypertension in patients with hypertrophic obstructive cardiomyopathy undergoing surgical septal myectomy.
Patients with hypertrophic cardiomyopathy often have concomitant pulmonary hypertension, which has a negative prognostic effect in patients undergoing myectomy. Our objective was to investigate the effect of myectomy on pulmonary artery pressure obtained via Swan-Ganz catheter and characterize how changes in pulmonary artery systolic pressure may indicate outcomes in these patients. ⋯ Postoperative pulmonary hypertension was associated with a higher rate of adverse cardiopulmonary events. This may influence the decision to use Swan-Ganz catheters in patients undergoing septal myectomy in monitoring pulmonary artery pressures to better risk stratify and manage these patients postoperatively.

The impact of prolonged mechanical ventilation after acute type A aortic dissection repair.
Patients with type A aortic dissection have increased resource use. The objective of this study was to describe the relationship between prolonged mechanical ventilation and longitudinal survival in patients undergoing type A aortic dissection repair. ⋯ The need for prolonged mechanical ventilatory support is prevalent and associated with other perioperative complications. More important, after adjusting for other covariates, prolonged mechanical ventilation is an independent factor associated with increased longitudinal mortality.
