Original Article


Repair of Ebstein anomaly has evolved over the last decade, and timing of repair remains variable. There have been no studies of exercise or functional capacity in patients who have had tricuspid valve surgery for Ebstein anomaly in adulthood. We aimed to compare exercise capacity before and after tricuspid valve repair or replacement for Ebstein anomaly in adults at Mayo Clinic. We performed a retrospective chart review of all patients with Ebstein anomaly who underwent tricuspid valve surgery at Mayo Clinic between June 2007 and January 2015. We compared pre- and postoperative echocardiograms, exercise tests, and clinic visits. Tricuspid valve surgery was done for 322 patients, and 32 patients met criteria of native tricuspid valve repair or replacement at age 18 or older and had maximal pre- and postoperative exercise tests. Nineteen patients had valve repair, and 13 had valve replacement. Surgery for Ebstein anomaly resulted in significant reduction in tricuspid regurgitation and right ventricular size. There was a significant improvement in NYHA functional class after surgery; however, there was no significant improvement in functional aerobic capacity (FAC), metabolic equivalents (METs), exercise time, or \({\text{V}}{{\text{O}}_{{2_{\hbox{max} }}}}\) after surgery. Patients who had an atrial shunt closed during surgery had improved minimum blood oxygen saturations during exercise, though no improvement in exercise capacity. In our cohort, patients who had tricuspid valve repair or replacement for Ebstein anomaly reported an improvement in functional capacity; however, this did not reflect improvement in measured exercise capacity, despite excellent surgical results by echocardiography.
