Prenatal diagnosis of partial absence of the tricuspid valve with perimembranous ventricular septal defect—The utility of prenatal 4‐dimensional spatiotemporal image correlation rendering

First described in 1965 by Johnson and Wilcox, partial absence of the tricuspid valve (TV) associated with a ventricular septal defect (VSD) is a very rare malformation (Ann Surg. 1966;164:334‐336). Heart failure secondary to severe TV regurgitation results in utero fetal compromise (J Am Coll Cardiol. 1991;17:167). We present here a fetus with partial absence of the tricuspid valve with perimembranous VSD.
