Both atria develop from a combination of the primitive atrium, sinus venous, and pulmonary veins.It However, underlying lesions such as hypertension, mitral valve disease, COPD, ASD, and TR greatly influence the degree of atrial enlargement. But, we rarely dispute it , & ask which atrium dilates more in AF ? Let us see few factors.
