Atrial fibrillation (AF) has become one of the most common sustained cardiac rhythm disturbance occurring mainly in MVD. Left atrial (LA) enlargement is one of the elements that evolve in the natural history of mitral stenosis.
Aims and Objectives: To study the LA size with AF among the patients with MVD and compare it with patients with non-valvular disease.
Materials and Methods: LA size of 67patients with MVD were studied in a prospective, cross sectional and observational single center study and compared with 52 patients with non-valvular disease in the Department of Cardiology, Hamidia hospital, Gandhi Medical College, Bhopal, India. Confirmation of AF was performed using a standard 12 lead ECG.ECHO was used to measure the dimensions of LA in patients with MVD with AF and patients with non- valvular heart disease.
Results: Out of 67 patients with valvular disease, majority were having age more than 30 years (71.64%).LA size among the patients with MVD, majority of them had it between 41-50 mm (56.7%) followed by 51-60 mm (28.3%). Out of 97 patients who had LA size >40 mm, majority were had MVD (94%) as compared to those with non-valvular disease patients (65.4%) (p< 0.001).
Conclusion: AF is more prevalent among the patients with MVD. The incidence of AF is more common when the Left Atrial size exceeds 40mm.
