Article Synopsis
- Extensive type A aortic dissections complicate choosing cannulation sites for cardiopulmonary bypass; researchers tested direct cannulation of the aortic arch using the Seldinger technique.
- A study of 24 patients revealed that direct cannulation had the shortest time to circulatory arrest and the best renal function post-surgery, with no permanent neurological deficits reported.
- The results suggest that this technique is effective for aortic dissection repairs, providing enhanced protection for both cerebral and peripheral organs.
We report the case of a patient who experienced near-infrared spectroscopy (NIRS)-detected transient regional cerebral desaturation during cardiopulmonary bypass for an operation to replace the aortic arch. Prompt institution of additional flow through an axillo-femoral graft was associated with restoration of regional cerebral saturation. The aortic surgery had no neurologic complications.

Methods: : Nineteen coronary anastomoses were performed on five patients who underwent off-pump coronary artery bypass surgery. Intracoronary shunting was adopted in all procedures.
Background: The aim of this study was to evaluate the midterm results of the initial phase of off-pump coronary artery bypass (OPCAB) surgery adoption in a single surgical unit, assessing the impact of procedural volume.
Methods: Study participants were 312 patients who underwent OPCAB during the period between August 2000 and January 2005 at S. Croce Hospital.
Background: Increasing numbers of elderly patients are now referred for mitral valve operations. It has been unclear whether the results offset the risk of intervention in this patient population.
Methods: We obtained clinical follow-up through May 2002 of 59 patients 80 years or older who underwent first-time isolated mitral valve repair (46 patients) or replacement (13 patients) for nonischemic, nonrheumatic mitral regurgitation from January 1990 to June 2000.
