Popis: Aims Thrombolysis is an alternative to surgery for mechanical prosthetic valve thrombosis (MPVT). Randomized clinical trials have yet to test the safety and efficacy of a proposed ultraslow thrombolytic infusion regimen. Methods and results This single-centre, open-label, pilot randomized clinical trial randomized adult patients with acute obstructive MPVT to an ultraslow thrombolytic regimen [25 mg of recombinant tissue-type plasminogen activator (rtPA) infused in 25 h] and a fast thrombolytic regimen (50 mg of rtPA infused in 6 h). If thrombolysis failed, a repeated dose of 25 mg of rtPA for 6 h was administered in both groups up to a cumulative dose of 150 mg or the occurrence of a complication. The primary outcome was a complete MPVT resolution (>75% fall in the obstructive gradient by transthoracic echocardiography, Conclusion The ultraslow thrombolytic regimen conferred a high thrombosis resolution rate without major complications. Such findings should be replicated in more adequately powered trials.
