Two dimensional echocardiography and Doppler in the right ventricular infarction

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Right ventricular infarction (RVI) diagnosis relies on evaluating right ventricular (RV) function and complications.
• Echocardiography offers valuable noninvasive insights into RV status during infarction.

Purpose of the Study:

• To assess the utility of two-dimensional and Doppler echocardiography in evaluating RV function and complications in patients with RVI.
• To identify key echocardiographic findings indicative of ischemic RV dysfunction and infarction.

Main Methods:

• Utilized two-dimensional and Doppler echocardiography to analyze RV function in patients with RVI.
• Examined indirect echocardiographic findings including RV dilatation, wall motion abnormalities, and paradoxical septal motion.
• Assessed the prevalence of complications such as RV aneurysm and thrombi.

Main Results:

• Right ventricular dilatation (diastolic dimension > 8 mm/m2 or RVDD/LVDD ratio > 0.63) suggests RV dysfunction but has low sensitivity.
• Wall motion abnormalities are the most sensitive and specific findings for RVI, often involving the posterior wall.
• Paradoxical septal motion is common, particularly in severe RV dysfunction.
• RV aneurysms and thrombi were identified in a subset of patients, with thrombi often adjacent to abnormal wall motion.

Conclusions:

• Echocardiography is crucial for diagnosing RV infarction and its complications.
• Wall motion abnormalities are more sensitive than hemodynamic data for detecting RVI.
• Echocardiographic assessment aids in identifying RV dysfunction, aneurysm, and thrombi, guiding patient management.
