Acute right ventricular infarction: insights for the interventional era

Area of Science:

• Cardiology
• Interventional Cardiology
• Acute Coronary Syndromes

Background:

• Acute right ventricular infarction (RV inf) presents significant morbidity and mortality risks.
• Hemodynamic compromise and arrhythmias are common during occlusion and reperfusion.
• RV function is crucial for maintaining cardiac output and systemic blood pressure.

Purpose of the Study:

• To review the pathophysiology of acute right ventricular infarction.
• To discuss the implications for interventional management.
• To highlight the benefits of acute reperfusion strategies.

Main Methods:

• Review of existing literature on right ventricular infarction.
• Analysis of hemodynamic consequences of right coronary artery occlusion.
• Evaluation of therapeutic interventions for RV inf.

Main Results:

• Proximal right coronary artery occlusion impairs RV systolic function, leading to hypotension.
• Distal occlusions may be compensated by right atrial contractility, while proximal occlusions worsen compromise.
• The right ventricle typically shows resilience and recovers function.
• Acute percutaneous mechanical reperfusion improves RV performance and patient outcomes.

Conclusions:

• Right ventricular infarction requires careful interventional management due to potential hemodynamic instability.
• Volume resuscitation, rhythm control, inotropes, and mechanical support are key management strategies.
• Early mechanical reperfusion is vital for enhancing RV recovery and improving survival in patients with RV infarction.
