Health Disparities in Exercise Performance in Patients with Repaired Tetralogy of Fallot.

Black patients with tetralogy of Fallot (TOF) have higher mortality than White patients. Health disparities related to other patient-important outcomes, such as exercise performance, have not been studied in this population. We aimed to determine if there are racial disparities related to exercise performance in patients with TOF and to investigate possible mediators of those disparities.

Scaffold Thrombosis After Percutaneous Coronary Intervention With ABSORB Bioresorbable Vascular Scaffold: A Systematic Review and Meta-Analysis.

Objectives: The aim of this study was to determine the risk of scaffold thrombosis (ST) after percutaneous coronary intervention (PCI) with placement of an ABSORB bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, California) by conducting a systematic review and meta-analysis.

Background: PCI with BVS placement holds great potential, but concern has recently been raised regarding the risk of ST.

Methods: MEDLINE/PubMed, Cochrane CENTRAL, and meeting abstracts were searched for all studies that included outcomes data for patients after PCI with BVS placement.
