Insights
A rare left atrial hemangioma causing aortic regurgitation was managed with aortic miniroot replacement and transcatheter coil occlusion. This case highlights a hybrid approach combining surgical and interventional techniques for complex cardiac tumors.
Area of Science:
- Cardiology
- Cardiac Surgery
- Interventional Cardiology
Background:
- A 59-year-old male presented with aortic regurgitation and a hypoplastic aortic valve.
- Echocardiography revealed a suspected hemangioma in the left atrial roof.
Observation:
- Preoperative evaluations included coronary angiography, echocardiography, and multislice computed tomography.
- The patient underwent aortic miniroot replacement, with intraoperative findings confirming the tumor's nature.
Findings:
- The left atrial hemangioma was not surgically resected due to its location, size, and bleeding risk.
- A transcatheter coil occlusion of a coronary fistula from the left circumflex artery was successfully performed as an alternative treatment.
Implications:
- This case underscores the value of a multimodality hybrid approach for diagnosing and treating complex cardiac conditions.
- Combining interventional and surgical techniques, facilitated by hybrid operating rooms, can optimize treatment strategies for cardiac tumors and fistulas.
Abstract:
We describe the case of a 59-year-old man who had aortic regurgitation and a hypoplastic aortic valve and for whom an echocardiography evaluation revealed a vascular tumor in the roof of the left atrium, which was suspected to be a hemangioma. After undergoing preoperative invasive catheter coronary angiography, echocardiography, and multislice computed tomography examinations, the patient underwent an aortic miniroot replacement. Intraoperative findings confirmed the findings of the preoperative evaluations. The tumor, although macroscopically verified as a hemangioma, was not resected because of the tumor's position and size, and the threat of uncontrollable bleeding. After an uneventful postoperative clinical course, a subsequent successful transcatheter coil occlusion of the coronary fistula from the left circumflex coronary artery was performed as an alternative to surgical resection of the tumor. This case emphasizes the future role of a multimodality hybrid approach for diagnosis, planning (different 2- and 3-dimensional imaging modalities), and treatment in the form of combining interventional (transcatheter) and surgical (open heart) techniques, which could optimize different treatment strategies. This approach could be further improved by increasing the installations of hybrid operating rooms.
