Morphologic features of the uniatrial but biventricular atrioventricular connection (original) (raw)

Hearts with an absent atrioventricular connection and a straddling solitary atrioventricular valve are rare anomalies that complicate surgical interventions, particularly for Fontan-like palliation. This study reviews 14 cardiac specimens to elucidate the segmental arrangements and valvar morphology associated with these anomalies. Key findings include a prevalence of right-hand ventricular topology, various valvar abnormalities, and consistent morphological features that indicate a likelihood of long-term valve insufficiency. The research underscores the necessity for a detailed understanding of valvar competencies to optimize surgical outcomes.
