A new cannula for antegrade selective cerebral perfusion.

Objective: Our aim was to perform antegrade selective cerebral perfusion with a different surgical technique using a new type of cannula.

Methods: This cannula has been designed to be introduced in the supra-aortic vessels directly using a standard guidewire technique (Seldinger technique). The cannula can also be inserted from the ostia of a vessel if preferred.

Performing Antegrade Selective Cerebral Perfusion Using the AV Cannula: A Novel Approach.

Antegrade selective cerebral perfusion has become the preferred choice for brain protection during aortic arch surgery. To perform antegrade selective cerebral perfusion, cannulas have been introduced directly into the ostia of the supra-aortic vessels (SAV) after institution of hypothermic circulatory arrest and opening the aortic arch. We describe a different surgical technique with a new type of cannula for antegrade selective cerebral perfusion.

A novel approach to ventricular rupture: clinical needs and surgical technique.

Cardiac rupture is a life-threatening event that often occurs after myocardial infarction and is often associated with significant death. Pericardiocentesis provides hemodynamic short-term improvement; however, patients with cardiac rupture require an emergency operation. This report describes a new procedure used to repair left ventricle free wall rupture after myocardial infarction.

Diagnosing left ventricular aneurysm from pseudo-aneurysm: a case report and a review in literature.

Rupture of the free wall of the left ventricle (LV) is a catastrophic complication occurring in 4% of patients after myocardial infarction (MI) and in 23% of those who die of MI. Rarely the rupture is contained by an adherent pericardium creating a pseudo-aneurysm. This clinical finding calls for emergency surgery.

Unexpected limited chronic dissection of the ascending aorta.

We report a rare case of a limited chronic dissection of the ascending aorta that was accidentally discovered at operation performed for severe aortic stenosis and moderate to severe dilatation of the ascending aorta. Preoperative investigations such as transoesophageal echocardiography and cardiac catheterization missed the diagnosis of dissection. Intraoperative findings included a 3.

Intraoperative microwave ablation in patients undergoing valvular surgery: midterm results.

Aim Of The Study: To assess the safety and efficacy of intraoperative microwave ablation to restore sinus rhythm and systolic atrial function in patients undergoing valvular surgery.

Methods: Forty-one patients with atrial fibrillation (AF) underwent operations. The mean age was 61 years (range, 45- 76 years).
