| pubmed-article:7875067 | pubmed:abstractText | About three and a half years after direct suture of a secundum atrial septal defect (ASD) the now 72-year-old patient developed heart failure with pulmonary congestion and pleural effusion which responded to medical treatment. The electrocardiogram showed atrial fibrillation with an irregular ventricular rate and right bundle branch block. Right heart catheterization established recurrence of the ASD with a left to right shunt of 60% (Qp/Qs = 2.5) and a pulmonary artery pressure of 45/12 mmHg. Because of the clinical state, the risk of re-operation and the suitable anatomy, non-operative percutaneous transvenous catheter closure of the defect with a double-umbrella device was indicated. Following this procedure the cardiomegaly regressed, while colour-Doppler echocardiography demonstrated a minimal residual left to right shunt. The pulmonary artery pressure had fallen to 32/13 mmHg. Three months later the patient was without symptoms and resumed her usual activity. The ECG now showed sinus rhythm, and there was no evidence of a shunt. Anticoagulation with acetyl salicylic acid (100 mg daily) was continued for 3 months. | lld:pubmed |
