Agent of choice for thrombolytic therapy (TT) in prosthetic valve thrombosis (PVT) is unknown. 84 mitral obstructive-PVT episodes treated with TT (43: Tenecteplase; 41: Streptokinase) were included in this prospective study. The incidence of primary end-point (CCS: complete clinical success, defined as complete or partial hemodynamic success with no complications or surgery) was 84.5% with recurrent PVT as a sole predictor. Bleeding and embolic manifestations were noted in 8.3% and 4.7% of episodes respectively. Tenecteplase use was associated with lower complication rate and a mitral EOA of <0.74 cm2 at presentation predicts the need for extended thrombolysis (accuracy, 78.6%).
