Key result
Cardiac MRI serves as a critical complementary tool to Doppler echocardiography for evaluating pulmonary regurgitation and serially monitoring right ventricular dilation to time surgical intervention.
Why the study?
Does Cardiac MRI improve the evaluation and monitoring of right ventricular impact in patients with pulmonary regurgitation compared to Doppler echocardiography?
Does Cardiac MRI improve the evaluation and monitoring of right ventricular impact in patients with pulmonary regurgitation compared to Doppler echocardiography?
Cardiac MRI is a critical complementary imaging modality to echocardiography for assessing right ventricular dilation and dysfunction in patients with pulmonary regurgitation to guide surgical timing.
May complement echocardiography for PR and RV monitoring; leaves open prospective validation of intervention thresholds.
Cardiac MRI (CMR) is a noninvasive diagnostic tool with comprehensive capabilities similar to that of two-dimensional echocardiography with Doppler. In addition to the ability to evaluate the etiology and severity of pulmonary valve regurgitation (PR), CMR is well designed to serially monitor the impact of the PR on the right ventricle (RV). Importantly, RV dilation and dysfunction is a critical determinate to time surgical intervention. CMR gives the silent RV, suffering from PR, a voice.

Sorrell et al. (2007) conducted a review in Pulmonary Regurgitation. Cardiac MRI (CMR) vs. Doppler Echocardiography was evaluated. Cardiac MRI serves as a critical complementary tool to Doppler echocardiography for evaluating pulmonary regurgitation and serially monitoring right ventricular dilation to time surgical intervention.
