Right Ventricular Dilation in Cardiac Arrest May Have Complicated Implications: A Case Report

Area of Science:

• Cardiology
• Critical Care Medicine
• Emergency Medicine

Background:

• Right ventricular (RV) dilation in cardiac arrest is often linked to pulmonary embolism.
• Recent evidence suggests diverse etiologies for RV dilation during cardiac arrest.

Observation:

• A case report of an elderly woman in cardiac arrest with an initially normal left ventricle to RV ratio.
• Development of RV dilation during resuscitation without other hemodynamic changes.

Findings:

• The case demonstrates RV dilation occurring independently of typical causes during resuscitation.
• This observation challenges the historical attribution of RV dilation solely to massive pulmonary embolism.

Implications:

• Highlights the complex and multifactorial nature of cardiac physiology during cardiac arrest.
• Underscores the need for further investigation into the mechanisms and causes of RV dilation in this critical setting.
