Why the study?
Double outlet ventricles are heterogeneous congenital malformations requiring individualized surgical approaches based on precise anatomic understanding, which can be optimally characterized by multimodality imaging.
Multimodality imaging is proposed as the optimal approach for characterizing the complex anatomy of double outlet ventricles to guide individualized surgical treatment.
Refines morphological classification of rare double outlet ventricles; leaves open standardized imaging protocols for individualized repair.
Hearts with double outlet ventricles and concordant atrioventricular connections account for about 1%-3% of all cases of congenital heart disease. We review hearts with two ventricles and concordant atrioventricular connections with double outlet right ventricle (DORV), double outlet left ventricle (DOLV) and double outlet both ventricles (DOBV) from the morphological and clinical imaging perspectives. These hearts are a heterogeneous group of congenital cardiac malformations with a wide range of pathophysiologies that require an individualised surgical approach based on a precise understanding of the complex cardiovascular anatomy. Owing to their differing temporal, spatial and contrast resolutions, we propose that multimodality imaging provides optimal characterisation of various intracardiac morphological features of double outlet hearts. This approach aids clinical diagnosis for optimising treatment options across these malformations.
