Background
Clinical Features
A patient may be asymptomatic or have any of the following features:
- Dyspnea on Exertion
- CHF
- Palpitations
- Syncope
- Pulmonary hypertension
- Right heart failure
- A. fib
- Stroke (via an embolism)
Differential Diagnosis
Congenital Heart Disease Types
- Cyanotic
- Acyanotic
- AV canal defect
- Atrial septal defect (ASD)
- Ventricular septal defect (VSD)
- Cor triatriatum
- Patent ductus arteriosus (PDA)
- Pulmonary/aortic stenosis
- Coarctation of the aorta
- Differentiation by pulmonary vascularity on CXR[1]
- Increased pulmonary vascularity
- Decreased pulmonary vascularity
- Tetralogy of fallot
- Rare heart diseases with pulmonic stenosis
Diagnosis
- An ECG may show the “crochetage” pattern (92% specific)—a notch near the apex of the R wave in electrocardiographic (ECG) inferior limb leads[2]
Management
Disposition
- Generally unless there is a complication, the septal defect if found incidentally can be evaluated as an outpatient with elective repair
