Mechanical Tricuspid Valve Thrombosis Successfully Treated With Tissue Plasminogen Activator

Rebecca Haraf et al. JACC Case Rep. .

Abstract

Prosthetic mechanical valve thrombosis has traditionally been managed with urgent surgical intervention. However, the risk of redo sternotomy can be prohibitively high in some patients. Thrombolytic therapy as a noninvasive treatment of mechanical valve thrombosis is a well-recognized alternative, but optimal dosing and patient selection remain incompletely characterized for right-side mechanical valves.

Keywords: 3D echocardiography; fluoroscopy; mechanical tricuspid valve; thrombolytics; thrombosis; tissue plasminogen activator.

Elevated Peak and Mean Prosthetic Tricuspid Valve Gradients Transthoracic echocardiogram with continuous-wave Doppler across the mechanical tricuspid valve (TV) in the apical 4-chamber view, demonstrating elevated velocity and mean gradient. Pressure half-time was 230 ms, consistent with valvular obstruction.
