A 60 year-old man with hepatic cirrhosis, was referred for chest pain, shortness of breath, and progressive cyanosis and an echocardiographic evaluation. PaO2 was 64 mm Hg on room air, but only 74 mm Hg on 100% oxygen. Chest X-ray and pulmonary function testing were normal. A contrast echocardiography using agitated saline (bubble study) was performed. A delayed appearance of a substantial amount of micro-bubbles in the left atrium greater than three cardiac cycles after appearance in the right atrium and ventricle was suggestive of pulmonary arteriovenous fistula (Figure 1A). The delayed appearance and a large amount of micro-bubbles in the left atrium preclude the intracardiac shunting result of a patent foramen ovale (PFO) or atrial septal defect (ASD). Interestingly, the density of micro-bubbles were same in the left and the right cardiac chambers even after 10 cardiac cycles (Figure 1B and 1C). When the injection was stopped, there were ... |
