A 30-year-old woman presented with frequent episodes of paroxysmal palpitation and electrocardiographic evidence of minimal pre-excitation of the left lateral accessory pathway. The patient underwent septostomy, which revealed air bubbles in the left ventricular cavity. Aspiration was done with a pigtail catheter via the retrograde aortic approach. Transient STelevation in the inferior leads was demonstrated. Left-sided hemiplegia was present after consciousness, which was completely resolved after 24 hours.
