Atrial Fibrillation Clinical Trial
Official title:
A Prospective Randomized Controlled Study of Additonal Left Atrial Appendage Electrical Isolation in Catheter Ablation Combined With Left Atrial Appendage Occlusion of Persistent Atrial Fibrillation
This project intends to enroll patients with persistent atrial fibrillation who are planning to undergo catheter ablation of atrial fibrillation. The two groups of patients were routinely performed atrial fibrillation pulmonary vein isolation and linear ablation with left atrial appendage occlusion. The experimental group received additional left atrial appendage electrical isolation before the left atrial appendage occlusion, and the control group did not perform left atrial appendage electrical isolation. We are intend to evaluate the safety and effectiveness of one-stop operation of left atrial appendage electrical isolation combined with left atrial appendage occlusion in the treatment of persistent atrial fibrillation.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Atrial fibrillation recurrence | outside the 3-month blank period after surgery, ECG and Holter recorded rapid atrial arrhythmia greater than 30S. | one year after operation | |
Primary | Stroke/TIA | Patients may have cerebral ischemia, such as sudden limb movement and sensory disturbance, aphasia, transient blindness in one eye, etc., disturbance of consciousness, or symptoms of vertebral artery ischemia, such as vertigo, tinnitus, hearing impairment, diplopia, Unsteady gait and difficulty swallowing, etc., patients may have obvious infarcts in the brain, which can be confirmed clinically by CT or MRI. | one year after operation | |
Primary | Systemic embolism | The clinical manifestations or evidence of embolism in the blood vessels of the system, including renal artery, splenic artery, mesenteric artery, etc. during the follow-up of the patient, and relevant examinations can be used to confirm the diagnosis. | one year after operation | |
Primary | Hospitalization rate due to heart failure | During the follow-up period, patients need hospitalization for heart failure, including acute heart failure, acute exacerbation of chronic heart failure, etc., which can be combined with clinical symptoms, signs, biochemical examinations (such as NT-proBNP) and cardiac ultrasound Wait for a clear diagnosis. | one year after operation | |
Primary | Cardiovascular death | The death of a patient due to cardiac structure, function, coronary artery disease, and arrhythmia can be diagnosed in combination with clinical practice. | one year after operation |
