Background and Aim: Mechanical prosthetic heart valves exert a
lifelong thromboembolic complication requiring continuous antithrombotic
therapy. Vitamin K antagonist is the recommended therapy of choice along with
meticulous INR monitoring to achieve and maintain an INR of 2.0-3.0.
The study aimed to assess the compliance of anticoagulant therapy in pediatric
patients after AVR and to highlight the challenges faced during follow-ups.Methods: A retrospective study was conducted at NICVD Hospital in Karachi,
Pakistan for a time frame of 2 years from 2020-2021 where 7 patients were
selected. Data were collected using hospital medical records and then validated through a
phone call mediated structured questionnaire-based interview.Results: 2 out of 7 patients in the case
