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 - NCT06125925Recruiting
Ablation for AFib in patients with heart failure and preserved ejection fraction
This study tests whether a catheter ablation procedure can help people with atrial fibrillation and a kind of heart failure where the heart pumps normally but doesn't relax properly (HFpEF). It looks at whether the procedure can improve symptoms and heart function.
NanjingAges 18–80 - NCT06166628Recruiting
Comparing two procedures for knee osteoarthritis pain
This study compares two minimally invasive procedures—embolization (blocking blood flow) and nerve ablation (blocking pain signals)—to see which works better for knee osteoarthritis pain. If you have long-lasting knee pain and are considering knee replacement surgery, this trial may help find another option.
Kingston, OntarioAges 40 years+ - NCT05265169Recruiting
Tested microwave ablation to treat liver metastases from colon cancer
This study tests whether a specific heating treatment (microwave ablation) can completely destroy small colon cancer spots in the liver. It may help patients who have limited liver tumors and need a precise, minimally invasive option.
Miami, FloridaAges 18 years+ - NCT05962892Recruiting
Study of thyroid cancer return risk after heat ablation
This study looks at what makes papillary thyroid cancer come back after a heat-based treatment called thermal ablation. It may help doctors better predict recurrence risk and guide follow-up after treatment.
BeijingAges 18 years+ - NCT06249347Recruiting
New ablation approach for persistent atrial fibrillation with stroke risk
This trial tests a new type of catheter ablation (using heat to create scar lines in the heart) for people with persistent atrial fibrillation who have a higher risk of stroke or bleeding. It aims to see if this approach can help prevent strokes and reduce the need for long-term blood thinners.
Wenzhou, ZhejiangAges 18 years+ - NCT05638841Recruiting
Study of repeat atrial fibrillation risk after ablation
This study follows adults who have had a procedure to treat an irregular heartbeat, to understand who is more likely to have it return. It may help doctors predict risk and plan follow-up after the procedure.
BeijingAges 18 years+ - NCT06278506Recruiting
Comparing surgery versus ablation for small kidney tumors
This trial compares two standard treatments for small kidney tumors: removing the tumor surgically (resection) or destroying it with heat or cold (ablation). The goal is to see which approach works better for tumors 3 cm or smaller.
StockholmAges 18–99 - NCT07855965RecruitingPhase 2
Ablation with immunotherapy and chemo before lung cancer surgery
This study tests a new approach for people with early-stage lung cancer that can be removed with surgery. Before surgery, patients receive a treatment called cryo-thermal ablation to freeze and heat the tumor, along with an immunotherapy drug (toripalimab) and chemotherapy. The goal is to see if this combination shrinks tumors and improves outcomes after surgery.
Chengdu, SichuanAges 18–80 - NCT05777551Recruiting
High-power short treatment for irregular heartbeat
This trial studies a specific heart-rhythm procedure that uses higher power for a shorter time to treat atrial fibrillation (AF), an irregular heartbeat. It may help some people control AF and reduce rhythm episodes, while doctors compare outcomes using their chosen approach.
