Insights
An arteriovenous fistula (FAV) can rarely cause heart failure after cardiac procedures. Surgical repair of this groin fistula resolved the patient's heart failure, highlighting the importance of clinical examination for diagnosis.
Area of Science:
- Cardiology
- Vascular Surgery
- Interventional Cardiology
Background:
- Arteriovenous fistulas (FAVs) are uncommon complications following cardiac catheterization.
- While most FAVs are asymptomatic, they can occasionally lead to significant morbidity.
Observation:
- A 70-year-old woman presented with high-output heart failure.
- The patient had a history of cardiac catheterization, and a subsequent examination revealed an arteriovenous fistula in the groin.
Findings:
- The arteriovenous fistula was successfully treated with surgical repair.
- Following the intervention, the patient's high-output heart failure symptoms resolved completely.
Implications:
- This case underscores the potential for iatrogenic arteriovenous fistulas to cause severe cardiovascular complications.
- Early clinical recognition and diagnosis of iatrogenic FAVs are crucial for timely intervention and favorable patient outcomes.
- Surgical correction of arteriovenous fistulas typically leads to the restoration of normal cardiac function.
Abstract:
The occurrence of an arteriovenous fistula is a potential complication of cardiac catheterization. Most of these fistulas cause no harm. We report the clinical case of a 70 years old woman with high-output heart failure caused by an arteriovenous fistula (FAV) in the groin. The fistula was successfully closed by surgical repair and the heart failure was resolved. This case confirms the potential harmfulness for the vascular bed of certain surgical/endovascular interventions and intravascular monitoring techniques. When heart failure of uncertain etiology appears in patients previously submitted to one of the above mentioned procedures, a careful clinical examination can lead to a correct diagnosis of iatrogenic FAV, whose surgical correction is usually followed by the restoration of a normal cardiac function.
