Clinical trials

The purpose of this clinical study is to evaluate the effectiveness and safety of a specialized medical device, the Naviscore scoring balloon, in preparing calcified coronary artery narrowings before the implantation of a drug-eluting stent. During percutaneous coronary interventions, the presence of calcified plaques in the heart arteries represents a major challenge because it can prevent stents from expanding fully. When a stent remains under-expanded, it significantly increases the long-term risk of arterial re-narrowing or blood clot formation. To optimize stent expansion, appropriate preparation of the diseased vessel section before stent insertion is a critical phase. This study is a prospective, multi-center randomized trial designed to test the hypothesis that treating calcified coronary lesions with the Naviscore scoring balloon will achieve a better stent expansion and a larger final minimal stent area compared to standard lesion preparation using regular non-compliant balloons. Eligible participants will be randomized in a one-to-one ratio to one of these two lesion preparation strategies. For all included patients, standard drug-eluting stents will be deployed. The study will use intravascular ultrasound imaging to evaluate the final minimum area of the stent directly inside the treated artery at the site of the highest initial calcium burden. Participant health and clinical outcomes will be monitored for up to twelve months following the procedure.

The goal of this randomized controlled trial is to compare the effectiveness of different treatments for laryngopharyngeal reflux disease (LPRD) in adult patients with confirmed symptoms and signs of the condition. The main question it aims to answer is: Which treatment (Proton Pump Inhibitors (PPIs), alginate, magaldrate, sucralfate, or diet) leads to the greatest improvement in LPRD symptoms and clinical signs over 3 months? Researchers will compare proton pump inhibitors to alternative medical treatments and dietary management to see which approach is most effective and better tolerated. Participants will: * undergo a clinical ENT examination with scoring of reflux signs (RSA) * complete symptom questionnaires (RSS) assessing severity, frequency, and impact of symptoms * receive one of the study treatments (medication or dietary intervention) * be evaluated at baseline and again after 3 months of treatment
