Overview

Thrombolysis may fail if pannus causes obstruction; this case report leaves open reliable noninvasive distinction from thrombus.

Structured PICO

How can clinical parameters, fluoroscopy, and echocardiography distinguish pannus from thrombus in mechanical valve obstruction?

P
Population
A patient with a St. Jude tricuspid valve obstruction (n=1)
I
Intervention
Clinical evaluation, fluoroscopy, and echocardiography
O
Outcome
Distinguishing pannus from thrombus as the etiology of mechanical valve obstruction

This case highlights the importance of using clinical parameters, fluoroscopy, and echocardiography to accurately distinguish between pannus and thrombus in prosthetic valve obstruction to guide appropriate therapy.
