“…[4] The first one, as in our case, can be identified as a parachute-like leaflet floating in the ventricular outflow tract, and may protrude into the sub-aortic region causing ventricular outflow obstruction. To the best of our knowledge, these findings have only been identified postnatally, with an estimated incidence of 1.4% and is thought to increase surgical mortality as well as be one of the causes of cardiac congestive heart failure in TOF, [1] requiring early surgery to avoid right ventricular failure. Preoperative knowledge of this lesion is expected to reduce surgical mortality.…”

Objective Tetralogy of Fallot (TOF) usually presents with a large non-restrictive ventricular septal defect (VSD). Case(s) We hereby report a rare case of prenatal diagnosis of TOF with a restrictive VSD secondary to redundant tricuspid valve tissue. Partial occlusion of the VSD resulted in prenatal progression to myocardial hypertrophy and postnatally to right heart failure with difficult management. Conclusion Prenatal signs of cardiac dysfunction in TOF should prompt a detailed exam of the VSD. Parents and neonatologists must be advised and delivery must be guaranteed in a tertiary center.

“…It has been described postnatally that in rare cases, the VSD can become restrictive and prompt cardiac failure. [1] We hereby present a rare case of prenatal diagnosis of TOF with a restrictive perimembranous VSD.…”
