[Isolated right ventricular infarct. Description of a case]

Area of Science:

• Cardiology
• Internal Medicine
• Pathophysiology

Background:

• Right ventricular infarction (RVI) is often associated with inferior myocardial infarction.
• Isolated RVI without concomitant left ventricular involvement is less common.
• Understanding the coronary anatomy, particularly dominance, is crucial for RVI diagnosis.

Observation:

• A case of extensive isolated right ventricular infarction is presented.
• The infarction resulted from proximal occlusion of a small right coronary artery.
• The patient had a dominant left coronary arterial system.

Findings:

• The diagnosis of isolated RVI requires specific electrocardiographic and echocardiographic evaluation.
• Management strategies focus on reperfusion and hemodynamic support.
• Literature review indicates variable clinical presentations and outcomes.

Implications:

• This case underscores the importance of considering RVI even in the absence of typical left ventricular strain patterns.
• Accurate diagnosis and timely intervention are critical for improving outcomes in RVI.
• Further research into the specific mechanisms and optimal management of isolated RVI is warranted.
