Assessment of Paravalvular Leak After TAVI by Hemodynamic Measurements and Cardiac MRI
Rationale: Transcatheter aortic valve implantation (TAVI) has become the standard therapy for elderly patients with high surgical risks. Paravalvular leakage after TAVI is relatively common and there is conflicting evidence regarding the clinical impact of mild paravalvular leakage in self-expanding devices. Prospective data for self-expanding devices are required to compare …

Concurrent Chemoradiation and Durvalumab for Locoregionally Advanced Nasopharyngeal Carcinoma
The investigators propose a phase II randomized-controlled study on using durvalumab in combination with induction chemotherapy followed by concurrent chemoradiation and adjuvant durvalumab, compared to induction chemotherapy followed by concurrent chemoradiation for previously untreated locoregionally advanced stage III to IVA NPC. In parallel, the investigators will also perform collateral tumor …
