Arterial switch operation is a surgical procedure used to correct certain congenital heart defects present from birth. It involves repositioning the major arteries to ensure proper blood circulation within the body. This procedure is typically performed early in life to prevent complications related to improper oxygen flow. Careful diagnosis and planning are essential before surgery. The goal is to restore normal heart function and improve oxygen delivery. Post-surgical care includes monitoring and gradual recovery. Patients require regular follow-up to assess heart function over time. Advances in surgical methods have improved the success of this procedure. Recovery varies depending on individual health conditions. With proper care, this surgery supports healthier heart development and long-term well-being.
