- Using a Swan-Ganz catheter to measure oxygen saturations upstream in the right atrium and downstream in the pulmonary artery can be used as a diagnostic method when suspecting a post-infarct VSD. Large discrepancies in oxygen readings with a much higher oxygenation in the pulmonary artery may indicate a left-to -right shunt.
- As an example of a temporary therapeutic role for a Swan-Ganz catheter, a case of temporary closure of a post-infarction ventricular septal defect (VSD) has been reported. A Swan-Ganz catheter was inserted through a femoral transvenous approach. This resulted in substantial improvement in the hemodynamic status of the patient. Six hr later, the patient underwent surgery for VSD closure. When immediate surgical intervention is not possible, it may be helpful to stabilize the patient until surgery can be performed. Thus, such a treatment has potential as a temporary measure for patients awaiting surgical repair of post-infarction VSD.[1]
