Prosthetic Valve Thrombosis Clinical Trial
— TROIAOfficial title:
Comparison of Different TRansesophageal Echocardiography Guided thrOmbolytic Regimens for prosthetIc vAlve Thrombosis
Despite high mortality and morbidity, the best treatment strategies for prosthetic valve thrombosis (PVT) have been controversial. In this study the investigators wanted to identify the most effective and safe regimen among different thrombolytic strategies.Transesophageal echocardiography (TEE) guided thrombolytic treatment was administered to 182 consecutive patients with PVT in 220 different episodes (156 women, mean age 43.2±13.06 years) between 1993 and 2009. These regimens included rapid streptokinase (Group I, 16 episodes), slow streptokinase (Group II, 41 episodes), high dose (100 mg) tissue plasminogen activator (t-PA) (Group III, 12 episodes), half-dose (50 mg) slow infusion (6-hours) of t-PA without bolus (Group IV, 27 episodes), and low dose (25 mg) and slow infusion (6-hours) of t-PA without bolus (Group V, 124 episodes). The study endpoints were thrombolytic success and in-hospital mortality and non-fatal complication rates.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Thrombolytic success | In the absence of fatal or nonfatal major complications; Obstructive thrombus: Doppler documentation of the resolution of increased gradient and decreased valve area. Clinical improvement in symptoms. Reduction by =75% in major diameter or area of the thrombus. Complete success was defined when all 3 criteria were met and partial success was defined as less than 3. Nonobstrucive thrombus: Complete success: =75% reduction in thrombus area. Partial success: 50%-75% reduction in thrombus area. |
24 hours | Yes |
Primary | Non-fatal complication rates | Nonfatal major complication: Ischemic stroke, intracranial hemorrhage, embolism (coronary or peripheral), bleeding requiring transfusion. Nonfatal minor complication: Bleeding without need for transfusion, TIA. |
