Figure 3. Clinical course during adulthood in patients undergoing atrial switch.

Illustration based on survival during adulthood of patients undergoing atrial switch in the CONCOR registry. ¹³ The percentage of patients with right ventricular (RV) dysfunction (defined as moderate or greater RV dysfunction on echocardiography), symptoms, and nonfatal clinical events (heart failure hospitalizations, transplant/ventricular assist device implantation, and symptomatic ventricular arrhythmias) is depicted for the third, fourth, and fifth decade of life. The dips in the curve signify the percentage of surviving patients enduring nonfatal clinical events during the decade. The figure illustrates that both morbidity and mortality rates are increasing as these patients grow older.
