Objectives

Narrative objectives1

Paravalvular leak(PVL) is often observed in patients post valve replacement or valve implantation with a reported frequency at 2-17%. Most patients with PVLs are asymptomatic hence requiring no additional therapy, however, small portion of patients can present with recurrent hemolytic anemia and/or heart failure due to paravalvular regurgitation.
Re-do surgery has been proposed as gold standard therapy for these symptomatic PVLs. However, re-do surgery per se are often underwent with high perioperative mortality and morbidity and recurrent PVLs are frequently observed after surgery due to calcification and fragility of the tissue.
Under those circumstances, transcatheter therapy for PVLs has been developed with a first successful report for consecutive four PVL cases in 1992. Recently, ACC/AHA guideline published in 2014 endorses transcatheter therapy for PVLs as class II.
For recent several years, transcatheter therapy for PVL has been performed in sporadic case scenarios as off label therapy in Japan. In 2014, specifically designed device for PVL developed by Occultech (Occultech PLD device) has obtained CE mark approval with favorable initial results.
RESEAL trial (tRancathEter cloSurE of pAravalvular Leaks) which is designed to assess safety and efficacy of Occultech PLD device in five independent institute in Japan is now under recruiting patients. RESEAL trial is built for the purpose of approval of this device in Japan and funded by Japan Medical Association. RESEAL trial will enroll total 30 patients with follow-up periods of six months post deployment. It started at 2016 December , plan to end at 2019 Mar.
In this prospective observational study, RESEALED (tRancathEter cloSurE of pAravalvular Leaks: Evaluation study post Deployment) study, patients enrolled in RESEAL trial will be followed every six months until 24 months post deployment to obtain clinical event and clarify long-term prognosis.

Assessment

Primary outcomes

Prognosis of patients underwent transcatheter closure of paravalvular leaks
: heart failure admissions, cardiovascular interventions( surgery, catheter intervention, device therapy), mortality(all-cause, cardiovascular)

Key secondary outcomes

Improvement of heart failure as assess by PVL grade,BNP,MLWHFQ,6MWD and NYHA class and
improvement of hemolytic anemia as assessed by hemoglobin, reticulocyte, LDH, serum bilirubin.
