The prognostic value of estimating stroke volume before and after exercise during treadmill stress echocardiography.

Background: Stress echocardiography (SE) is an established technique for assessment of coronary artery disease (CAD) which is difficult to perform and interpret. Left ventricular stroke volume (SV) is readily estimated with Doppler echocardiography. It can be affected by myocardial ischemia, with possible adjunctive value during SE.

Echocardiographic Pulmonary to Left Atrial Ratio (ePLAR): A Comparison Study between Ironman Athletes, Age Matched Controls and A General Community Cohort.

Background: During exercise there is a proportionally lower rise in systemic and pulmonary pressures compared to cardiac output due to reduced vascular resistance. Invasive exercise data suggest that systemic vascular resistance reduces more than pulmonary vascular resistance. The aim of this study was the non-invasive assessment of exercise hemodynamics in ironman athletes, compared with an age matched control group and a larger general community cohort.

Dramatic Normalization of the Echocardiographic Pulmonary-to-Left Atrial Ratio with Thrombolysis in a Case of Life-Threatening Submassive Pulmonary Emboli.

• A 74 year old male presented with bilateral submassive pulmonary emboli with moderately severe pulmonary hypertension with right ventricular systolic pressure (RVSP) 63 mm Hg. • Echocardiographic pulmonary-to-left atrial ratio (ePLAR) markedly elevated at 0.78 m/s (normal range for age 0.

The New Dimension in Aortic Measurements - Use of the Inner Edge Measurement for the Thoracic Aorta in Australian Patients.

Background: Historically, aortic measurements were established using M-mode echocardiography, measuring from the leading edge to leading edge. Improvements in echocardiographic imaging now permit accurate assessment using the blood-tissue interface. Normal values have not been established using this technique.
