ABLATION

This study tests a new device that uses electrical pulses to shrink benign (non-cancerous) thyroid nodules without surgery. About 100 adults with symptomatic nodules will receive the treatment and be followed for up to a year. The goal is to reduce nodule size and improve symptom…

This study tests a new device that uses short electrical pulses to treat atrial fibrillation (an irregular heartbeat) while people are already having heart surgery for other reasons. About 135 adults aged 18-85 with a history of atrial fibrillation will take part. The goal is to …

This study is for people with breast cancer who cannot have surgery due to health reasons or choose not to for cosmetic concerns. It tests a device that uses extreme cold and heat to destroy tumors, which are then absorbed by the body. The goal is to see if this minimally invasiv…

This study compares two types of heart ablation (a procedure that scars tiny areas of heart tissue to stop abnormal electrical signals) for treating dangerous fast heart rhythms that can occur after a heart attack. About 220 adults who have an implanted defibrillator and have had…

This study tests a new minimally invasive treatment that freezes and then heats breast tumors, comparing it to standard breast-conserving surgery. About 264 women aged 50+ with early-stage, hormone-positive breast cancer will be randomly assigned to one of the two treatments. The…

This study tests a new device that helps doctors steer catheters during heart rhythm tests or treatments in children. About 25 kids (up to age 21) already scheduled for a heart procedure will have the device used at the end. Researchers will check if it works safely and improves …
