The evaluation of mitral valve stenosis: comparison of transthoracic echocardiography and cardiac magnetic resonance.

Aims: Echocardiographic assessment of patients with mitral valve stenosis (MS) requires a detailed evaluation of mitral valve anatomy, mitral valve area (MVA), and pressure gradient and presence concomitant valve diseases. Our aim was to evaluate planimetric MVA and transmitral flow velocities using cardiac magnetic resonance (CMR) in patients with isolated MS and to compare with transthoracic echocardiography (TTE) to determine the reliability.

Methods And Results: Thirty-one patients (mean age 50.
