Isolated right ventricular mechanical alternans in right ventricular infarction

Area of Science:

• Cardiology
• Cardiac Electrophysiology

Background:

• Right ventricular infarction (RVI) can present with complex hemodynamic changes.
• Mechanical alternans, typically associated with left ventricular function, is rarely described in the right ventricle.

Observation:

• This study describes the phenomenon of isolated mechanical alternans specifically in the right ventricle.
• The observed alternans occurred in the context of acute right ventricular infarction.

Findings:

• Right ventricular mechanical alternans can be an isolated finding.
• The pattern of right ventricular infarction can closely resemble conditions like cardiac tamponade or pericardial constriction.

Implications:

• Recognizing isolated right ventricular mechanical alternans is crucial for accurate diagnosis of RVI.
• Distinguishing RVI from tamponade or constriction based on clinical presentation and imaging is essential for appropriate management.
