ABSTRACT
Abstract Right ventricular restrictive physiology (RVRP) occurs in diverse clinical scenarios, most frequently after repair of Tetralogy of Fallot (TOF). Cardiac magnetic resonance (CMR) can comprehensively evaluate RVRP using 4D flow along with anatomical and fibrosis characterization. Also, RVRP is associated with less pulmonary regurgitation and fewer right ventricle enlargement; its long term protective role is debated. RVRP is a challenging and relevant diagnosis, which hallmark is the presence of antegrade pulmonary arterial Flow in late diastole throughout the respiratory cycle. Also, other hemodynamic findings could aid such us flow in; caval veins, suprahepatic, coronary sinus and tricuspid valve. Obtaining all these flow curves is virtually impossible by echocardiography. CMR with 4DF is a unique and powerful technique enabling this comprehensive hemodynamic evaluation as depicted in this case.
