VExUS and right ventricular to pulmonary artery uncoupling.

Area of Science:

• Cardiology
• Critical Care Medicine
• Diagnostic Imaging

Background:

• Right ventricular (RV) dysfunction is a critical determinant of patient outcomes.
• Pulmonary artery (PA) pressure and RV function are closely linked.
• Assessing the RV-PA interface is crucial for managing cardiovascular conditions.

Purpose of the Study:

• To introduce the VExUS score as a novel tool for assessing RV-PA uncoupling.
• To highlight the role of bedside ultrasonography in VExUS score determination.
• To emphasize the importance of identifying the etiology of abnormal VExUS scores.

Main Methods:

• Development and validation of the VExUS scoring system.
• Utilization of point-of-care ultrasonography for VExUS score assessment.
• Systematic evaluation of potential causes for elevated VExUS scores.

Main Results:

• The VExUS score effectively detects uncoupling between the right ventricle and pulmonary artery.
• Bedside ultrasonography provides a feasible method for VExUS score calculation.
• Etiological diagnosis is facilitated by assessing abnormal VExUS scores.

Conclusions:

• The VExUS score serves as an important alert for RV-PA uncoupling.
• Bedside ultrasonography is the primary modality for initial VExUS score assessment.
• Determining the etiology of an abnormal VExUS score is the essential next step in clinical management.
