Why the study?

What is the role of CT and MR imaging in detecting complications after aortic valve replacement compared to conventional echocardiography?

Structured PICO

What is the role of CT and MR imaging in detecting complications after aortic valve replacement compared to conventional echocardiography?

Population

Patients with complications after aortic valve replacement

Intervention

Computed tomography (CT) and magnetic resonance (MR) imaging

Comparator

Conventional imaging (transthoracic echocardiography, transesophageal echocardiography, and fluoroscopy)

Outcome

Detection and monitoring of complications (e.g., paravalvular leak, dehiscence, endocarditis, obstruction, structural failure, pseudoaneurysm formation, aortic dissection, and hemolysis)

Cardiac CT and MR imaging are valuable complementary tools to echocardiography for diagnosing specific complications following aortic valve replacement.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Supports selective CT/MR after inconclusive echocardiography for prosthetic valve dysfunction; leaves open prospective validation of algorithms.
