A Comparison Between Gore Cardioform and Amplatzer Septal Occluder for Percutaneous Closure of Patent Foramen Ovale Associated With Atrial Septal Aneurysm: Clinical and Echocardiographic Outcomes.

Objectives: To evaluate the short- and long-term clinical and echocardiographic outcomes of the percutaneous closure of the patent foramen ovale (PFO) with an atrial septal aneurysm (ASA) using 2 different devices.

Methods: We enrolled 100 patients with PFO and ASA. Fifty consecutive patients had transcatheter closure of the PFO with the Gore Cardioform septal occluder (GSO) (Gore Medical) and a second group of 50 consecutive patients with the Amplatzer PFO occluder (APO) (Abbott).

Platypnea and orthodeoxia syndrome as an uncommon clinical indication for a challenging percutaneous patent foramen ovale closure: a case report.

Background: Platypnea and Orthodeoxia Syndrome (POS) is a rare clinical condition characterized by positional dyspnoea and arterial desaturation. Various mechanisms are related to this syndrome. The simultaneous presence of abnormal anatomical findings [aortic root dilatation, atrial septal aneurysm (ASA), Lipomatous septum, and patent foramen ovale (PFO)] and an occurring ventilation/perfusion mismatch can modify intracardiac haemodynamics leading to POS in elderly patients.
