Case ReportsAcute ascending aortic dissection diagnosed with transthoracic echocardiography.
A 79-year-old man with a known ascending aortic aneurysm presented to his physician's office with an episode of severe "tearing" type chest pain after lifting several boxes. Physical examination was notable for low blood pressure and a new diastolic murmur. ⋯ This demonstrated a dissection flap clearly seen superior to the sinuses of Valsalva and severe aortic insufficiency. Computed tomography or transesophageal echocardiography is typically the initial test of choice, but transthoracic echocardiography can rapidly confirm the diagnosis of acute ascending aortic dissection.

Controlled Clinical TrialAssessment of intraventricular mechanical dyssynchrony and prediction of response to cardiac resynchronization therapy: comparison between tissue Doppler imaging and real-time three-dimensional echocardiography.
We studied the comparability of left ventricular (LV) mechanical dyssynchrony assessment by tissue Doppler imaging (TDI) and real-time three-dimensional echocardiography (RT3DE) in patients with a wide range of LV ejection fractions and different causes of cardiomyopathy. In addition, we evaluated the ability of both techniques to predict response to cardiac resynchronization therapy (CRT). ⋯ Marked differences between techniques are found for the presence of mechanical dyssynchrony when current cutoff values are applied, making interchangeability of these techniques uncertain. Assessment of mechanical dyssynchrony by RT3DE might be an appropriate alternative to TDI for accurate prediction of response to CRT.

Controlled Clinical TrialNon-invasive coronary flow reserve after successful primary angioplasty for acute anterior myocardial infarction is an independent predictor of left ventricular recovery and in-hospital cardiac events.
The prediction of left ventricular (LV) recovery and adverse cardiac events after reperfused acute myocardial infarction (AMI) is challenging. The aim of this study was to assess the usefulness of noninvasive coronary flow reserve (CFR) to predict LV recovery and in-hospital adverse cardiac events after AMI by comparison with other available tools. ⋯ Noninvasive CFR determined < 24 hours after AMI was an independent predictor of LV recovery at 3-month follow-up and of in-hospital adverse cardiac events.
