ABSTRACT

Introduction. Left atrial isomerism (LAI) is a complex entity with various treatments and outcomes. The aim of the study was to analyze the surgical outcomes of patients with LAI undergoing cardiac surgery. Methods. A retrospective study was carried out on patients with a diagnosis of LAI who underwent cardiac surgery were included, between January 1, 2010 and March 31, 2020. The demographic characteristics and perioperative conditions were described. Results.Twenty- seven patients were included; the median age was 6 years (IQR 3 -11), 40.7% males. The main diagnoses in patients undergoing the univentricular approach were atrioventricular canal (25.9%) and pulmonary atresia (11.1%), while cases undergoing the biventricular approach were atrial septal defect (44.4%) and ventricular septal defect (40.7%). The most common surgical procedures were modified Blalock–Taussig shunt (18.5%) in the univentricular approach and repair of septal defects (4.6%) in the biventricular approach. No early or late deaths were found. Conclusions. The survival of LAI in our center is similar to that of other referral centers. Patients with LAI must undergo a rigorous evaluation to determine an appropriate surgical strategy.
