Use of tenecteplase for left-sided prosthetic valve thrombosis.

Introduction: Prosthetic valve thrombosis (PVT) following cardiac valve replacement in rheumatic heart disease patients is a common cause for referral to tertiary care centre. Although surgery has been described as the traditional choice of therapy, thrombolytic therapy has reported high success rates in published literature. Case report: This is a case report of ten patients with left-sided PVT receiving tenecteplase. The mean dose of tenecteplase used was 1.01 mg/kg given as IV bolus injection along with enoxaparin, heparin and acenocoumarol. The diagnosis and response was assessed based on trans-thoracic echocardiography. The reduction in peak transvalvular gradient was in the range of 46% - 81% and in mean transvalvular gradient was in the range of 50% - 84%. There was normalization of valve motion in all patients. There was no incidence of mortality, intracerebral hemorrhage, systemic bleeding or embolism. Conclusion: To our knowledge, this is the largest published evidence so far showing efficacy and safety of tenecteplase for PVT.
