Cardiomyopathy Trial, Recruiting

Written by an AI model from the ClinicalTrials.gov eligibility criteria and checked on a sample basis. Please confirm against the original criteria.

Who might be able to join this trial:

• You have been diagnosed with, and your doctor has recommended, a heart procedure called catheter ablation to treat an irregular heartbeat — specifically ventricular tachycardia, premature ventricular complexes, atrial tachycardia, or atrial fibrillation (having had a previous ablation procedure does not disqualify you).
• At least one episode of your irregular heartbeat has been recorded by a heart monitor (such as an ECG, Holter monitor, implanted device, or similar) within the past 12 months.
• You are 18 years of age or older.
• You are willing and able to sign a consent form agreeing to take part in the study.
• You are able and willing to attend all required appointments and follow-up visits before, during, and after the study.

Who may not be able to join:

• Your irregular heartbeat is caused by a treatable or temporary condition, such as an electrolyte imbalance, thyroid disease, or a cause not related to the heart.
• You need a procedure involving the left side of your heart, and a scan has shown that a specific part of your heart (left atrium) is larger than 55mm.
• Your heart's pumping strength (called ejection fraction) is at or below 25% and you have a ventricular (lower chamber) irregular heartbeat.
• Your heart's pumping strength is at or below 40% and you have an atrial (upper chamber) irregular heartbeat.
• A scan taken within 24 hours before the procedure found a blood clot inside your heart.
• You cannot take blood-thinning medications such as heparin, warfarin, or dabigatran.
• You have a history of abnormal blood clotting or bleeding problems.
• You have had a heart attack within the past 2 months.
• You have had a blood clot or a mini-stroke (TIA) within the past 12 months.
• Your heart failure is not controlled, or your doctor has classified your heart failure as the most severe level (NYHA Class IV).
• You have had a pacemaker, heart defibrillator, or heart closure device implanted within the past 6 weeks.
• You have a known allergy to contrast dye used in medical imaging that cannot be treated.
• You currently have an active illness, infection, or sepsis (a serious body-wide infection).
• You have a heart tumour, abnormal tissue, or a physical barrier inside your heart that would make the procedure impossible.
• You have a significant birth defect or other serious medical condition that your doctor believes would make participation unsafe (confirm with trial site).
• You have previously had a heart valve procedure or surgery, including valve repair or replacement, or have an artificial heart valve.
• You currently have, or have had within the last 7 days, a temporary heart support device (such as an Impella) in place.
• You have had any heart surgery, including a coronary artery procedure (PCI), within the past 2 months.
• You have had a procedure to close a hole between the upper chambers of your heart within the past 6 weeks.
• You have a condition that prevents doctors from accessing your blood vessels to carry out the procedure.
• You are pregnant, breastfeeding, or of childbearing age and plan to become pregnant during the study.
• You are considered a vulnerable individual requiring special protections (confirm with trial site).
• You are currently taking part in another clinical study testing a different medical device or drug.
