MRI-guided prostate cancer ablation with ultrasound from the urethra
This trial tests a newer way to treat certain low- to intermediate-risk prostate cancers using MRI guidance and an ultrasound probe placed through the urethra. It aims to destroy the tumor while using imaging to help target it more precisely.
Rochester, MinnesotaAges 45–80 - NCT07657897Recruiting
Anesthesia effects on inflammation in liver cancer treatment
This study looks at how different types of anesthesia or sedation affect inflammation in people with early-stage liver cancer who are having a procedure called radiofrequency ablation (RFA). RFA uses heat to destroy small tumors, and researchers want to see if the choice of anesthesia influences the body's immune response, which might help improve recovery.
Cluj-Napoca, ClujAges 18–80 - NCT06929897Enrolling by invitation
Comparing Two Ablation Methods for Persistent Atrial Fibrillation
This study compares two types of ablation (a procedure that uses energy to fix irregular heartbeats) for people with persistent atrial fibrillation. It tests whether adding extra treatment to the back of the heart's left upper chamber helps improve outcomes compared to standard treatment alone.
SeoulAges 20–80 - NCT03035747Recruiting
Registry for treatment of varicose veins
This study collects information about people who have varicose veins with abnormal backflow in the leg veins. It’s meant to track how treatments for chronic venous problems are working over time, which can help improve care for others in the future.
Saint PetersburgAges 18 years+ - NCT03718364Recruiting
Atrial fibrillation ablation registry study in Switzerland
This study records information from people undergoing a procedure to treat atrial fibrillation called pulmonary vein isolation. It helps doctors understand how the procedure is used and what outcomes to expect.
BaselAges 18 years+ - NCT03729232Recruiting
Japanese registry for people who had catheter ablation
This is a national registry that collects health information from people in Japan who received catheter ablation. It may help doctors and researchers understand outcomes and improve future care.
Suita, OsakaAges Any age - NCT03981497Recruiting
Microwave treatment for small, hard-to-remove liver and kidney tumors
This trial tests using a “microwave ablation” procedure to destroy small liver or kidney tumors when surgery isn’t an option or can’t remove everything. It may help patients avoid major surgery by targeting tumors directly with heat.
MilanAges 18 years+ - NCT05034432RecruitingPhase 4
Test treatment for dangerous heart rhythm episodes in LVAD patients
This trial studies a procedure to fix abnormal heart rhythms (ventricular tachycardia or ventricular fibrillation) in people who have an LVAD and a defibrillator (ICD) or an alternative device. It may help prevent future dangerous rhythm episodes after LVAD treatment.
Phoenix, ArizonaAges 18 years+ - NCT04150744RecruitingPhase 2
New immune drug plus immunotherapy for liver cancer
This Phase 2 trial tests whether adding a new drug (RFA) to an immunotherapy medicine (carrizumab) works better than carrizumab alone for hepatocellular carcinoma, a type of liver cancer. It may help people whose tumors cannot be removed or transplanted and who have not started whole-body (systemic) cancer treatment yet.
Hangzhou, ZhejiangAges 18–75 - NCT04365751Recruiting
Microwave ablation versus surgery for liver cancer
