Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients with hyperthyroidism or hypothyroidism are often combined with atrial fibrillation, but after the stabilization of thyroid hormone levels after treatment, the patients' atrial fibrillation still persists. Radiofrequency ablation of the atrial fibrillation as one of the treatment options for atrial fibrillation has been widely used in the clinic, and has significant efficacy in maintaining sinus rhythm, improving cardiac function, and improving the prognosis of patients. However, there is a lack of clinical monitoring data on radiofrequency ablation of atrial fibrillation in patients who have combined thyroid dysfunction and have stabilized their thyroid hormone levels after treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In patients recommended by guidelines for atrial catheter radiofrequency ablation of atrial fibrillation, catheter radiofrequency ablation was performed after exclusion of contraindications, and was observed and compared between patients with comorbid pre-existing thyroid hormone disorders and patients without comorbid atrial fibrillation after radiofrequency ablation:1: time to sexual rhythm maintenance: incidence of cardiac-related complications and incidence of noncardiac-related complications within 3 months and 1 year,2: walking distance on a six-minute walk test within 3 months,1 year, comparison of percent left ventricular ejection fraction, and comparison of left ventricular diastolic diameter at the time 3 months,1 year,.To comprehensively assess the efficacy and safety of catheterized radiofrequency ablation of atrial fibrillation in patients with comorbidities of prior thyroid hormone disorders.

Combined Thyroid Dysfunction

Atrial catheter radiofrequency ablation for atrial fibrillation combined with patients requiring prior thyroid hormone abnormalities

Catheter Ablation

Intervention Type PROCEDURE

catheter radiofrequency ablation therapy for atrial fibrillation involves the use of ablative energy to destroy the cardiomyocytes at the opening of the pulmonary veins, which blocks the electrical conduction pathway between the pulmonary veins and the left atrium, so that atrial fibrillation no longer occurs.

Uncomplicated thyroid dysfunction

Atrial catheter radiofrequency ablation for atrial fibrillation in patients with uncomplicated need for prior thyroid hormone abnormalities

Catheter Ablation

Intervention Type PROCEDURE

catheter radiofrequency ablation therapy for atrial fibrillation involves the use of ablative energy to destroy the cardiomyocytes at the opening of the pulmonary veins, which blocks the electrical conduction pathway between the pulmonary veins and the left atrium, so that atrial fibrillation no longer occurs.
