Catastrophic right coronary artery dissection after surgical removal of coronary chimney stents following valve-in-valve transcatheter aortic valve implantation

Key Result

Surgical removal of coronary chimney stents after valve-in-valve transcatheter aortic valve implantation led to catastrophic right coronary artery dissection in a 64-year-old woman.

Key Points

• To describe a rare case of catastrophic right coronary artery dissection following valve-in-valve transcatheter aortic valve implantation.
• Detailed case examination of a 64-year-old woman post-surgery
• Review of surgical techniques and interventions used during valve-in-valve implantation
• Assessment of complications arising after stent removal
• Catastrophic dissection of the right coronary artery occurred post-surgery
• Patient had a history of surgical aortic valve replacement
• Elevated surgical risk underscored the complexity of the intervention
