Indicators of deterioration of clinical status such as impaired exercise tolerance, ventricular arrhythmia, and sudden cardiac death have all been associated with chronic PR. The degree of PR is one of the most important factors determining RV dysfunction; thus, pulmonary valve replacement becomes necessary to retain lower RV volumes, increase the RV systolic function, and lower the mortality rates. [...]our study aimed to discover the optimal index for the assessment of the degree of PR. This retrospective study included 57 consecutive patients with repaired TOF who had undergone CMR evaluations from June 2008 to September 2017, and had evidence of PR on echocardiography. The indications for pulmonary valve replacement in repaired TOF are variable, including severe PR, abnormal cardiac function, decreased exercise intolerance, heart failure symptoms, and severe arrhythmia.
