Atrial septal defect
ICD-10 Q21.1 is a billable code used to indicate a diagnosis of atrial septal defect.
An atrial septal defect (ASD) is a congenital heart defect characterized by a hole in the septum that divides the two upper chambers of the heart (the atria). This defect allows oxygen-rich blood from the left atrium to flow into the right atrium, leading to increased blood flow to the lungs. ASDs can vary in size and may be classified into several types, including ostium primum, ostium secundum, and sinus venosus defects. Symptoms may not be apparent in infancy but can manifest later in childhood or adulthood, including fatigue, shortness of breath, and palpitations. If left untreated, ASDs can lead to complications such as pulmonary hypertension, atrial arrhythmias, and heart failure. Diagnosis typically involves echocardiography, which can visualize the defect and assess its hemodynamic significance. Treatment options may include monitoring, medication, or surgical intervention, such as catheter-based closure or open-heart surgery, depending on the size of the defect and the presence of symptoms.
Detailed clinical history, physical examination findings, and results from echocardiograms or other imaging studies.
Routine well-child visits where ASD is diagnosed, pre-operative assessments for surgical intervention, and follow-up visits post-repair.
Consideration of growth and development milestones in children with ASD, as well as the impact of the defect on exercise tolerance.
Family history of congenital heart defects, genetic testing results, and any syndromic associations.
Genetic counseling for families with a history of congenital heart defects and evaluation of syndromic conditions that may include ASD.
Awareness of chromosomal abnormalities that may be associated with ASD, such as Down syndrome (Trisomy 21).
Used to evaluate the presence and severity of ASD.
Complete echocardiographic report detailing findings.
Pediatric cardiology may require specific imaging protocols.
An atrial septal defect (ASD) is a hole in the septum between the heart's upper chambers (atria), while a ventricular septal defect (VSD) is a hole in the septum between the lower chambers (ventricles). Both are congenital heart defects but differ in location and potential complications.
