“…There are currently no studies on the use of ESE in the adult population with coarctation repair as the primary focus has been on the pediatric and adolescent population. These studies have found Doppler mean gradients of >30 mmHg through the descending aorta with systemic HTN during exercise suggest re-coarctation with the need of reintervention [37]. Bicycle exercise reduced systolic myocardial reserve in patients with repaired coarctation as noted by reduced isovolumic acceleration and TDI's, and diastolic reserve, as noted by TDI e' [38].…”
