Quantitative assessment of right ventricular structure and flow dynamics in pulmonary homograft obstruction

Percutaneous pulmonary valve implantation

“…Recent advances in cardiac MRI imaging allow detailed quantitative assessment of the structure of the right ventricle as well as the flow dynamics in the setting of pulmonary homograft dysfunction ( Figures 1 and 2 ). 16 This quantitative assessment aids in the clinical determination of the need and timing of re-intervention in asymptomatic patients.…”

“…Randomized data comparing the outcome of the surgical and percutaneous approaches on the right ventricle are lacking. With the advent of recent advances in cardiac MRI quantitative assessment, 16 it would be intriguing to evaluate the structural and dynamic effects of both approaches on the right ventricle.…”
