Minimally invasive closure of patent foramen ovale through port-access surgery

We present here our experience of patent foramen ovale closure through a mini-invasive surgical technique. With the new surgical platform termed Heartport System, it is possible to install extra-corporeal circulation and to obtain cardioplegic arrest of the heart with endovascular techniques. This allows the operation of closure to be entirely performed through a micro-thoracotomy (Port-access surgery) in the right 4th intercostal space. Sixty-one patients underwent this surgical correction and seventeen of them (26%) had a diagnosis of patent foramen ovale, 12 with an history of cerebrovascular accidents. They are all alive and well after a mean follow-up of 16 months, with no recurrence of the inter-atrial communication and free from new neurological events. The post-operative course was uneventful with patients discharged on postoperative day 4. This technique shows a 100% efficacy, minimise surgical trauma, allows a quick recovery and offers excellent cosmetic results with no scarring. We believe that this procedure must be regarded as the "golden standard" for the closure of atrial septal defects
