Baseline Echo: All walls show normal thickening and endocardial excursion. No regional wall motion abnormalities are noted. Global left ventricular function is normal. The left atrium is top normal in size. There is mild mitral regurgitation. There is mild right ventricular dilation with normal right ventricular systolic function. There is mild tricuspid regurgitation with an estimated right ventricular systolic pressure of 38 mmHg. E wave is 0.9 with an E prime of 0.08 and an E to E prime ratio of 11. An intra-atrial septal aneurysm is noted without left to right shunt noted by color flow Doppler.
Exercise Echo:
Post exercise all walls become hyperdynamic. All walls show normal thickening. No regional wall motion abnormalities are noted. Overall left ventricular function is hyperdynamic. Estimated right ventricular systolic pressure rose to 62 mmHg post exercise.
Conclusions:
1. Both echo and ECG portion of exercise stress echo are negative for ischemia.
2. Intra-atrial septal aneurysm noted without evidence by color flow Doppler of shunt flow.
3. There is mild dilation of the right atrium and right ventricle with estimated right ventricular systolic pressure of 38 mmHg at rest and rises to 62 mmHg post exercise.
