Imaging in mitral stenosis

Abstract

Purpose of review Mitral stenosis remains clinically relevant in developing countries where rheumatic heart disease is the predominant culprit. In the western world, mitral annular and valvular calcification is an increasingly recognized cause, particularly in an aging population. Echocardiography plays a primary role in imaging mitral stenosis with a growing role for cardiac computed tomography and magnetic resonance imaging. In this review, we aim to revisit mitral stenosis assessment and quantification using multimodality imaging. Recent findings There is an increasing role for advanced cardiac imaging especially in the era of transcatheter mitral valve intervention. Also, when echocardiography is suboptimal or discordant with symptoms, computed tomography can provide anatomical data, whereas magnetic resonance imaging can provide anatomical along with hemodynamic data. Summary Diagnosis of mitral stenosis is crucial as it carries an increased morbidity and mortality risk. Echocardiography is the cornerstone imaging modality with alternative, complementary advanced imaging considered when images are suboptimal.

Is 3d Transthoracic Planimetry Still Superior Over 2d Echo in Rheumatic Mitral Stenosis When Both Area and Hemodynamic Parameters of Severity Are in Question?

“…12 3D planimetry is considered to work well in those cases when complex asymmetric geometry of the mitral is encountered like in rheumatic mitral stenosis but still the results are conflicting. [13][14][15] The objective of the study was to compare transthoracic 3D planimetry to 2D planimetry in calculating mitral valve area along with correlation of various echocardiographic parameters of severity of mitral stenosis among these modalities.…”
