FIGURE 5-2 Valvular disease.


Though echocardiography is the primary imaging modality used to assess valvular structures, regurgitation, and stenosis, cardiac MRI is useful in patients with suboptimal echocardiographic images. Valve leaflet thickness and mobility can be assessed. In addition, quantification of valvular regurgitation may be completed using phase and volumetric techniques.


A, Mitral regurgitation. A 72-year-old African American male with longstanding hypertension presented with progressive heart failure. On cardiac MRI, this WB LV inflow view demonstrates an enlarged LV with significant mitral regurgitation, represented by the black jet in the white blood extending from the valve into the left atrium.


B, Tricuspid stenosis. A 30-year-old female presented with symptoms of progressive right heart failure, increasing abdominal pain, ascites, and lower extremity edema over the past few months. Cardiac MRI demonstrated a normal RV but thickened tricuspid valve leaflets. The right atrium is markedly enlarged, and an incidental right pleural effusion can be seen on this WB horizontal long-axis view.


C, Ebstein anomaly. Cardiac MRI demonstrates a markedly enlarged right atrium and RV on this WB horizontal long-axis view. The tricuspid valve leaflets are not well visualized. The leftward bowing of the atrial septum is consistent with increased right-sided pressures. The patient was a 70-year-old female who presented with a vague history of cardiac murmur and 6-month history of abdominal swelling and lower extremity edema. Echocardiography demonstrated inferior displacement of the septal leaflet of the tricuspid valve, a dilated right atrium and RV, and severe tricuspid regurgitation consistent with Ebstein anomaly.
