Superior sinus venosus atrial septal defect
ICD-10 Q21.14 is a billable code used to indicate a diagnosis of superior sinus venosus atrial septal defect.
Superior sinus venosus atrial septal defect (ASD) is a congenital heart defect characterized by an abnormal opening between the right atrium and the left atrium, specifically located near the superior vena cava. This defect allows oxygen-rich blood from the left atrium to flow into the right atrium, leading to increased blood flow to the right side of the heart and lungs. Over time, this can result in right atrial and ventricular enlargement, pulmonary hypertension, and heart failure if left untreated. Patients may present with symptoms such as fatigue, palpitations, or exercise intolerance, although many may remain asymptomatic for years. Diagnosis is typically made through echocardiography, which can visualize the defect and assess its hemodynamic significance. Surgical intervention may be required, especially in symptomatic patients or those with significant right heart volume overload. The prognosis is generally good with appropriate management, but long-term follow-up is essential to monitor for potential complications.
Detailed pediatric history, including prenatal and perinatal factors, growth and development assessments, and symptomatology.
Evaluation of a child with unexplained fatigue or exercise intolerance, routine screening in high-risk populations, and preoperative assessments.
Consideration of age-related physiological changes and their impact on the presentation and management of congenital heart defects.
Family history of congenital heart defects, genetic testing results, and syndromic associations.
Genetic counseling for families with a history of congenital heart disease, evaluation for syndromic conditions associated with ASDs.
Awareness of chromosomal abnormalities that may co-occur with congenital heart defects, such as Down syndrome (Trisomy 21) or Turner syndrome.
Used during surgical intervention for ASD repair.
Operative report detailing the procedure and findings.
Pediatric cardiology may require specific documentation related to congenital heart surgery.
Common symptoms include fatigue, palpitations, and exercise intolerance. Some patients may remain asymptomatic for years, making routine screening important.
