Clinical Scorecard: Progressive Aortic Regurgitation and Persistent Atrial Fibrillation in a Case of Bilateral Coronary Artery Fistulas Complicated by Acute Heart Failure and Pulmonary Hypertension

At a Glance

Key Highlights

• Bilateral coronary-to-pulmonary artery fistulas identified via imaging.
• Patient experienced progressive heart failure and persistent atrial fibrillation.
• Successful atrial fibrillation catheter ablation and transcatheter closure of CAFs.
• Significant recovery in cardiac function observed during follow-up.
• Importance of comprehensive cardiac evaluations in atypical presentations.

Guideline-Based Recommendations

Diagnosis

• Utilize imaging techniques such as echocardiography and coronary angiography to confirm CAF presence.
• Assess for associated complications like arrhythmias and heart failure.

Management

• Consider surgical or transcatheter closure for symptomatic or large CAFs.
• Implement guideline-directed medical therapy for heart failure and arrhythmia.

Monitoring & Follow-up

• Regular follow-up with echocardiography and cardiac MRI to assess cardiac remodeling.
• Monitor for recurrence of atrial fibrillation and heart failure symptoms.

Risks

• Potential for ischemia, arrhythmia, heart failure, and pulmonary hypertension.
• Risk of sudden cardiac death in untreated cases.

Patient & Prescribing Data

Adults with symptomatic coronary artery fistulas and associated cardiac complications.

Individualized treatment strategies integrating pharmacological, interventional, and surgical approaches are essential.

Clinical Best Practices

• Conduct thorough cardiac evaluations in patients with atrial fibrillation and heart failure.
• Tailor management strategies based on the complexity of CAFs and associated conditions.
• Utilize a multidisciplinary approach for optimal patient outcomes.
