Paradoxical increase in ambulatory SBP in coarctation of aorta a compared to essential hypertension.

Background: The relationship between office vs. ambulatory blood pressure (BP) indices are well-studied in patients with essential hypertension and based on these data, it is known that the average 24-h ambulatory BP is typically lower than office BP. However, emerging data show that office SBP underestimates arterial afterload in patients with coarctation of aorta (COA), and a minimal increase in stroke volume during low-intensity exercise results in an exaggerated rise in SBP as compared to those with essential hypertension.

Recurrent sustained atrial arrhythmias and thromboembolism in Fontan patients with total cavopulmonary connection.

Background: Total cavopulmonary connection (TCPC) is associated with a lower risk of incident atrial arrhythmias as compared to atriopulmonary Fontan, but the risk of recurrent atrial arrhythmias is unknown in this population. The purpose of this study was to determine the incidence and risk factors for recurrent atrial arrhythmias and thromboembolic complications in patients with TCPC.

Methods: This is a retrospective multicenter study conducted by the Alliance for Adult Research in Congenital Cardiology (AARCC), 2000-2018.
