Right ventricular diverticulum following a pulmonary valve placement for correction of tetralogy of Fallot: A case report

Figure 1 Cardiac magnetic resonance imaging cine sequences (June 2022). A: Four chamber view: Enlargement of the right ventricle and increased right ventricle trabeculation; B: Systolic image showing tricuspid valve regurgitation; C: Short axis in diastole; D: Short axis in systole. No saccular lesion of the right ventricle was observed in this study.

Figure 2 Cardiac magnetic resonance (June 2022). A: Flow-versus-time graph shows valvular pulmonary insufficiency a regurgitant volume of 39.1 mL per beat and regurgitant fraction of 48.8%; B: Valvular tricuspid insufficiency; a regurgitant volume of 6.4 mL per beat and regurgitant fraction of 10.3%; C: Cardiac magnetic resonance (June 2024). Flow-versus-time graph shows paravalvular leak a regurgitant volume of 4.8 mL per beat and regurgitant fraction 14.8%.

Figure 3 Cardiac magnetic resonance cine sequences (June 2022). A: Phase-contrast imaging; Right ventricular outflow tract stenosis and increased velocity; B and D: Late gadolinium enhancement sequence; Right atrial enhancement and right ventricular outflow tract; C: Cine sequence; Right ventricular outflow tract obstruction.

Figure 4 Cardiac magnetic resonance (February 2024) diverticulum of the inferolateral wall of the right ventricle after pulmonary valve prosthesis. A: Four chamber view: Diastole; B: Four chamber view: Systole; C: Four chamber saccular image in the inferolateral wall of the right ventricle, which showed synchronous movement and contraction like the rest of the myocardium.
