Giant left main coronary artery to right atrium fistula

Area of Science:

• Cardiology
• Vascular Surgery
• Medical Case Reports

Background:

• Coronary artery fistulae (CAFs) are abnormal connections between a coronary artery and a cardiac chamber or vessel.
• Aneurysmal origin of CAFs is exceptionally rare, posing unique diagnostic and therapeutic challenges.
• Giant fistulae, particularly involving the left main coronary artery, are seldom reported.

Purpose of the Study:

• To report a rare case of a giant left main coronary artery to right atrium fistula with aneurysmal origin.
• To illustrate the clinical presentation and diagnostic considerations for this rare anomaly.
• To discuss the available management options and their implications.

Main Methods:

• Case presentation of a 48-year-old male with a giant coronary artery fistula.
• Review of diagnostic imaging findings, including echocardiography and coronary angiography.
• Discussion of treatment strategies based on fistula characteristics and patient condition.

Main Results:

• Successful diagnosis of a giant left main coronary artery to right atrium fistula originating from an aneurysm.
• Detailed description of the patient's clinical course, including symptoms and hemodynamic impact.
• Evaluation of potential management pathways, considering surgical and interventional approaches.

Conclusions:

• Giant coronary artery fistulae with aneurysmal origin represent a significant clinical challenge due to their rarity and complexity.
• Accurate diagnosis through advanced imaging is crucial for appropriate management planning.
• Multidisciplinary decision-making is essential to determine the optimal treatment strategy, balancing risks and benefits.
