Video 14.4 subxiphoid window profiling major straddling of the mitral valve in an infant with double-outlet right ventricle
Modified long-axis view obtained from a subxiphoid window profiling major straddling of the mitral valve in an infant with double-outlet right ventricle (DORV) {S,D,D}. Note the commissure of the straddling valve with attachments within the infundibulum and the marked degree of straddling that would complicate biventricular repair.
