MoscowAges 18–70 - NCT05543798Recruiting
MRI-guided heart procedure for dangerous abnormal rhythms
This trial studies a heart rhythm procedure (“ablation”) for people with ischemic cardiomyopathy who have ongoing episodes of sustained ventricular tachycardia. It aims to reduce these dangerous rhythm events, especially when standard anti-rhythm medications don’t work or can’t be used.
Leipzig, SaxonyAges 18 years+ - NCT07403760Recruiting
Ablation for atrial fibrillation in patients 80 and older
This study investigates whether a catheter ablation procedure can improve wellbeing and reduce the risk of serious events for people 80 and older with symptomatic atrial fibrillation. The goal is to see if this treatment offers better outcomes than standard care in this age group.
BeijingAges 80 years+ - NCT06096246Recruiting
Comparing treatments for persistent atrial fibrillation
This study compares two treatments for persistent atrial fibrillation (AF) that lasts more than 7 days but less than 2 years: electrical cardioversion (a shock to reset your heart rhythm) versus catheter ablation (using radio waves to fix the heart's electrical pathways). It aims to find which option works better for patients like you.
LondonAges 18–85 - NCT06505798Recruiting
Ablation vs medication for heart failure with atrial fibrillation
This trial compares a procedure called ablation (using cold, heat, or electric pulses to fix irregular heartbeats) with standard medications to see which better treats heart failure in people who also have atrial fibrillation. It may help if your heart's pumping ability is reduced and you still have symptoms despite medications.
HalifaxAges 18 years+ - NCT07551947Enrolling by invitation
Insulin Resistance and Heart Rhythm Ablation Success
This study examines whether how your body handles insulin (a hormone that controls blood sugar) affects the success of a new ablation procedure called pulsed field ablation, which treats irregular heart rhythms. Researchers want to understand which patients benefit most from this treatment.
TřinecAges 18 years+ - NCT06719921Enrolling by invitation
Catheter ablation for atrial fibrillation without x-ray
This study tests a way to perform catheter ablation for atrial fibrillation using a non-fluoroscopic lab, meaning no x-ray is needed during the procedure. It may help patients avoid radiation exposure.
Hangzhou, ZhejiangAges 18 years+ - NCT05239364Recruiting
Ablation for an abnormal heart rhythm after prior AF surgery
This trial tests a procedure to “ablate” (treat) a specific fast heart rhythm in the upper chambers of the heart that happens after previous atrial fibrillation (AF) ablation or heart surgery. It may help by stopping the rhythm and reducing symptoms, while doctors check how well the targeted mapping and ablation work.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT07459387Recruiting
