Percutaneous treatment of simultaneous aortic dissection and pericardial tamponade during coronary intervention

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Surgery

Background:

• Percutaneous coronary intervention (PCI) is a common procedure for coronary artery disease.
• Complications, though rare, can be severe and life-threatening.
• Left main stem involvement presents unique challenges in PCI procedures.

Observation:

• An unexpected dissection of the left main coronary artery occurred during PCI.
• The dissection propagated to involve the ascending aorta.
• This complication led to the development of pericardial tamponade, a medical emergency.

Findings:

• The patient underwent pericardial drainage and achieved hemodynamic stabilization.
• Extensive stenting was performed to manage the propagating dissection.
• Successful non-surgical management allowed for safe patient discharge.

Implications:

• This case demonstrates the feasibility of conservative management for complex PCI-related dissections.
• Highlights the importance of prompt recognition and multidisciplinary management of aortic and pericardial complications.
• Offers insights into stenting strategies for extensive dissections involving the aorta.
