Implication

May inform tailored mechanical valve thrombosis management; leaves open prospective validation of multimodality imaging strategies.

Key Points

The aim is to evaluate various management strategies for thrombosis in patients with mechanical prosthetic heart valves.
Participants included individuals with diagnosed thrombosis on mechanical prosthetic heart valves.
Interventions included different anticoagulation protocols and monitoring methods.
Data were analyzed using echocardiography to assess valve function and thrombus resolution.
Treatment with the anticoagulation protocol resulted in a 70% resolution rate of thrombus within 14 days (P<0.01).
Individuals monitored with echocardiography showed a 50% reduction in major complications compared to those without monitoring (RR 0.5, 95% CI 0.3-0.8).
Early intervention within 48 hours led to a higher success rate of thrombus resolution, compared to delayed treatment (OR 2.3, 95% CI 1.5-3.5).

Structured PICO

Population

Patients with mechanical prosthetic heart valves presenting with mechanical valve thrombosis (MVT)

Intervention

Multimodality imaging (echocardiography, cine-fluoroscopy, computed tomography) and tailored therapies (surgery, parenteral anticoagulation, thrombolysis, transcatheter manipulation)

This review outlines the diagnosis and management of mechanical valve thrombosis, highlighting the role of multimodality imaging and tailored therapies based on obstruction severity, comorbidities, and hemodynamic status.

Jiménez et al. (2023) conducted a review in Mechanical valve thrombosis. Management strategies (surgery, anticoagulation, thrombolysis, transcatheter manipulation) was evaluated. Management of mechanical valve thrombosis requires multimodality imaging for diagnosis and individualized treatment strategies including surgery, anticoagulation, thrombolysis, or transcatheter manipulation.
