STUDY THE CLINICAL AND LEFT ATRIAL MORPHOLOGY IN ATRIAL FIBRILLATION PATIENTS TREATED BY RADIOFREQUENCY ENERGY AT MILITARY HOSPITAL 103
Main Article Content
Abstract
Objective: To investigate the clinical characteristics and morphology of the left atrium in atrial fibrillation patients indicated for radiofrequency ablation. Subjects and methods: Cross-sectional descriptive study in 57 atrial fibrillation patients, treated with radiofrequency ablation at Hospital 103. Results: The main symptom of AF patients is palpitations, accounting for 77.2%; Hypertension accounts for the highest rate of cardiovascular risk factors of AF patients with 57.9%; Most patients have CHA2DS2-VA scores from 2 - 3; The average left atrial diameter on echocardiography is 36.70 ± 5.36 mm, on CT scan is 38.69 ± 6.95 mm; The diameter of the right superior pulmonary vein is the largest; The persistent AF group has the left atrial size on echocardiography and CT scan tends to be larger than in the paroxysmal AF group. Conclusion: Palpitations are the main symptom of AF patients, and hypertension is the most common risk factor. Patients with persistent AF have larger left atrial diameters than patients with paroxysmal AF. The right superior pulmonary vein is the largest among the pulmonary veins. The correlation between the size of pulmonary veins on CT scan and clinical characteristics of AF patients is unclear.
