förmaksvägg

Förmaksvägg, often translated as atrial septum, is a term used in anatomy and medicine to describe the wall that separates the left atrium and the right atrium of the heart. This septum is a crucial component of the heart's structure, ensuring that oxygenated blood returning from the lungs mixes minimally with deoxygenated blood from the body before it is pumped to the rest of the system. In a healthy heart, the förmaksvägg is intact and functions to maintain the separation of these two blood flows.

A common congenital condition related to the förmaksvägg is an atrial septal defect (ASD). This is a hole in the septum that allows blood to pass between the left and right atria. The size and location of the ASD can vary, and in some cases, the defect may close on its own. However, larger defects can lead to an imbalance in blood flow, potentially causing the right side of the heart to enlarge and increasing the risk of complications such as heart failure or stroke. Medical imaging techniques like echocardiography are used to diagnose and assess the severity of ASDs. Treatment options range from observation to surgical or interventional closure of the defect.
