Echocardiography can be used for rapid and accurate risk stratification of patients with pulmonary embolism to appropriately direct the therapeutic strategies for those at high risk. Echocardiography is an ideal risk stratification tool in this regard because of its easy portability to the emergency room or to the bed side. It can be performed at a relatively low cost and at no risk to the patient. Furthermore, echocardiography allows repetitive noninvasive assessment of the cardiovascular and hemodynamic status of the patient and the response to the therapeutic interventions. Right ventricular hypokinesis, persistent pulmonary hypertension, a patent foramen ovale, and a free floating right heart thrombus are echocardiographic markers that identify patients at a higher risk for morbidity and mortality. Such patients warrant special consideration for thrombolysis or embolectomy.

The IVC dimension is larger in the supine position independent of the cardiac cycle. This may be due to increased intra-abdominal pressure and compression of the IVC by the liver in the left lateral position. HV systolic and diastolic peak Doppler velocities were not influenced by position.

Cardiovascular risk factors have utility in risk prediction but have limitations in predicting individual risk. Identifying an individual’s risk remains a challenge. Emerging technologies such as carotid artery ultrasonography and measures of carotid intima‐media thickness (CIMT) may be useful in identifying the susceptible patient who may benefit from more aggressive preventive therapy. This screening test is noninvasive, reproducible, inexpensive, and radiation‐free. Recent data have improved our understanding of the application of CIMT as a screening tool for cardiovascular disease. CIMT measurement may place an individual into a higher‐ or lower‐risk category, allowing for appropriate institution of preventive strategies.

Quantitative assessment of global and regional RV function during SE was feasible using VVI analysis. Longitudinal velocity and SR of the RV basal lateral wall were significantly better than longitudinal displacement or strain for detecting RV response during SE.

Pectus excavatum exists as varying anatomic deformities and compression of the right heart by the chest wall can lead to patient symptoms including dyspnea and chest pain with exertion. Echocardiography can be difficult but is critical to the evaluation and diagnosis of this patient population. Modifying standard views such as biplane transthoracic and 3-D transesophageal views may be necessary in some patients due to limitations from the abnormal anatomy of the deformed anterior chest wall. Apical four-chamber views when seen clearly can usually visualize any extrinsic compression to the right ventricle of the heart.
