M-mode echocardiography in acute pulmonary embolism

Area of Science:

• Cardiology
• Diagnostic Imaging

Background:

• Acute pulmonary embolism (PE) is a critical condition affecting the pulmonary circulation.
• Accurate and timely diagnosis of PE is essential for patient outcomes.

Purpose of the Study:

• To evaluate the utility of M-mode echocardiography in diagnosing acute pulmonary embolism.
• To identify echocardiographic signs indicative of acute PE.

Main Methods:

• M-mode echocardiography was performed on twenty-two patients diagnosed with acute pulmonary embolism.
• Both ventricles and the right branch of the pulmonary artery were examined using precordial and suprasternal approaches.

Main Results:

• Significant pulmonary embolism was associated with dilatation of the right ventricle and the right branch of the pulmonary artery.
• The size of the right pulmonary artery branch was significantly different in PE patients compared to healthy volunteers.
• No significant correlation was found between echocardiographic anatomic changes and lesser circulation hemodynamics.

Conclusions:

• Echocardiography, specifically M-mode, is a suitable complementary diagnostic method for acute pulmonary embolism.
• Echocardiographic findings of right ventricular and pulmonary artery dilatation are key indicators of acute PE.
