Aortic valve-sparing operation has been progressively widely performed for the treatment of aortic root aneurysm. Nowadays, this procedure has been proposed even in presence of a bicuspid aortic valve, severe aortic regurgitation or in primary aortic dissection repair. We present our ten-year experience focusing on mid-term echocardiographic follow-up. ⋯ The durability of valve reimplantation was found to be excellent in patients with tricuspid aortic valve and normal or nearly normal cusps. Cusp prolapse and complication after cusp repair turned out to be the main causes for early failure.

Aim of the paper was to assess the reliability of preoperative cross-flow determination by transcranial Doppler measurement (TCD) to detect clamping ischemia in patients undergoing carotid endarterectomy with selective shunting. ⋯ TCD scanning is highly reliable to detect cross-flow prior to carotid surgery and thus helpful to identify patients at risk for clamping ischemia and need for shunting.

Comparative Study
On or off pump coronary bypass? Insight from matched and principal component analyses of 8779 operations.
The aim of this paper was to compare the clinical impact of the different myocardial protection strategies in coronary artery bypass grafting (CABG) patients to facilitate decision-making for use of on- or off-pump technique. ⋯ Comparatively, on-pump techniques were associated with greater risk of adverse events in "high risk" patients defined by clinical characteristics, while off-pump was associated with increased risk of adverse events in "low risk" patients.

He aim of this paper was to investigate the incidence of and the indications for conversion to general anesthesia (GA) in a large single-center series of patients undergoing carotid surgery under cervical plexus block (CPB). ⋯ Cervical plexus block for carotid surgery is associated with a low rate of conversions to GA. Neurological deterioration upon carotid clamping and local anesthetic toxicity are identified as the most common indications for such intervention.

Acute type B aortic dissection is a life threatening disease process, which remains a clinical dilemma despite advances in technology, surgical technique and postoperative management. The variability of presenting symptoms, lack of a consensus on indications for treatment and differing opinions about the optimal timing for repair have added to the management confusion. Medical management has been the standard of care for acute uncomplicated type B dissection. ⋯ Recent data suggest that early TEVAR lowers aortic-related events and improves long-term aortic specific survival by covering the entry tear, promoting false lumen thrombosis and inducing aortic wall remodeling. The paucity of supporting data has created controversy surrounding the optimal treatment strategy for acute type B dissection. Nonetheless, recent healthcare trends show a paradigm shift towards the utilization of early TEVAR in acute type B dissection.
