Use of the transseptal puncture in transcatheter closure of long tunnel-type patent foramen ovale.
Two patients with long tunnel-type patent foramen ovale presented for elective transcatheter closure following transient ischaemic attack and stroke. Right to left shunting was confirmed on transthoracic and transoesophageal echocardiography. A new technique that used a transseptal procedure was devised to enable closure of the tunnel-type patent foramen ovale using the CardioSEAL transseptal occluder to avoid "bunching up" of the device and residual transatrial shunting.
