Isolated Pulmonary Regurgitation without Right Heart Remodeling or Pulmonary Hypertension

Area of Science:

• Cardiology
• Cardiovascular Imaging
• Clinical Case Reports

Background:

• Isolated moderate pulmonary regurgitation (PR) is a rare clinical entity, often lacking specific characterization in medical literature.
• PR is typically associated with pulmonary hypertension or congenital heart disease, making its isolated form a diagnostic and management challenge.
• This case report focuses on a rare presentation of isolated moderate PR in the absence of right heart remodeling or pulmonary hypertension.

Purpose of the Study:

• To describe a rare case of isolated moderate pulmonary regurgitation.
• To highlight the clinical approach and diagnostic evaluation for this condition.
• To emphasize the importance of long-term monitoring in managing isolated PR.

Main Methods:

• A case report of a 71-year-old woman presenting with palpitations and syncope.
• Diagnostic evaluation included echocardiography to assess cardiac structure and function.
• Management focused on controlling arrhythmias and optimizing blood pressure, with planned serial echocardiography for monitoring.

Main Results:

• Echocardiography revealed moderate pulmonary regurgitation with normal right ventricular size and function.
• No acute intervention was required; management was conservative.
• Serial echocardiography was planned to monitor PR progression and right ventricular function.

Conclusions:

• Isolated moderate PR without right heart remodeling is rare and requires advanced imaging for evaluation.
• Long-term monitoring is essential to detect potential progression to right ventricular dysfunction.
• Potential etiologies include primary valvular degeneration or arrhythmia-related strain, guiding future management and follow-up.
