Double-Chambered Right Ventricle Presenting in Late Adulthood in a Patient With Left Heart Disease.

• DCRV is a rare finding in older adults. • DCRV can be seen in association with a wide range of cardiac abnormalities. • Cardiac imaging characterizes anatomy, hemodynamics, and associated cardiac lesions.

Blood pressure changes during routine transthoracic echocardiography.

Background: Increased afterload affects many of the flow dependent metrics assessed during transthoracic echocardiography (TTE) especially in the evaluation valvular disease. A single timepoint blood pressure (BP) may not accurately reflect the afterload present at the time of flow-dependent imaging and quantification. We assessed the magnitude of change in BP at discrete timepoints during routine TTE.

Automated Detection of Aortic Stenosis Using Machine Learning.

Background: Aortic stenosis (AS) is a degenerative valve condition that is underdiagnosed and undertreated. Detection of AS using limited two-dimensional echocardiography could enable screening and improve appropriate referral and treatment of this condition. The aim of this study was to develop methods for automated detection of AS from limited imaging data sets.
