Transient Apical Thickening Following Apical Ballooning Syndrome: A Case Series.

The authors describe transient apical thickening mimicking apical hypertrophic cardiomyopathy following apical ballooning syndrome. These findings are observed on multimodality cardiac imaging and appear to constitute a novel entity. Possible pathophysiologic mechanisms are explored.

Three methods for evaluation of left atrial volume.

Aim: To compare and contrast 3 different echocardiographic methods used to measure left atrial (LA) volume: biplane area length (AL), biplane modified Simpson (SIMP), and prolate ellipse (PE) methods.

Methods And Results: A review of consecutive patients who presented to our outpatient echocardiography laboratory for a resting transthoracic study between April 2006 and May 2006 was performed. Echocardiograms were reexamined and LA volume measured using the AL, SIMP, and PE methods.

Contrast echocardiography: experience in a clinical echocardiography laboratory.

Although 2-dimensional echocardiography with adjunct intravenous contrast media improves endocardial visualization and enhances quality of spectral Doppler signals, widespread use of contrast agents has not occurred for various reasons. Results from this study indicate that discretionary use of contrast media will enhance endocardial and Doppler signal visualization scores without an impact on total procedure duration, lending credence to an argument for a lower threshold for discretionary use of contrast media.
