Quizplus · Accepted Answer

Atrial septal defect (ASD) can lead to enlargement of the right atrium due to the increased volume of blood that needs to be handled. This enlargement can predispose individuals to atrial fibrillation due to the stretching and remodeling of the atrial tissue. Additionally, the increased blood volume in the right side of the heart can lead to increased pressure in the venous system, manifesting as jugular venous distension. Asthma is a respiratory condition and is not directly related to the hemodynamic changes caused by ASD.
