ABSTRACT: AIM: The PAS-Port® Proximal Anastomosis System (Cardica, Inc, Redwood City, CA, USA) has been used worldwide since March 2003. The objective of the present study was to evaluate the clinical outcome of the PAS-Port® Proximal Anastomosis System. METHODS:All the patients who underwent off-pump coronary artery bypass grafting in the Catharina Hospital Eindhoven between August 2006 and April 2010 were included in a non-randomized retrospective case-control study, if they had at least one proximal vein graft anastomosis. Study end-points consisted of overall survival, coronary reintervention and postoperative stroke. RESULTS:The study included 312 patients (201 cases, 111 controls). After 36 months of follow-up there was no difference in survival between cases and controls (92.2% vs. 93.7%, P=0.52). No significant difference could be detected between cases and controls with respect to overall coronary reintervention-free survival (93% vs. 96.4%, P=0.20) and freedom from coronary reintervention due to proximal vein graft failure (98% vs. 100% P=0.14). The use of the PAS-Port system could not be identified as an independent risk factor of coronary reintervention (p=0.21). Postoperative stroke rates of cases and controls (2% vs. 0.9%, P=0.42) were comparable. CONCLKUSION:The clinical outcomes in patients treated with the PAS-Port® Proximal Anastomosis System were satisfactory compared with those treated with the conventional hand-sewing technique. The use of the PAS-Port system was not associated with higher adverse outcome in terms of overall survival, stroke, coronary reintervention-free survival and freedom from reintervention due to proximal vein graft failure.

ABSTRACT: The purpose of this study was to investigate the effect of using antegrade selective cerebral perfusion (ASCP) with moderate hypothermia on hospital mortality after surgery for acute type A aortic dissection (AAAD).
Between January 1998 and December 2008, 142 consecutive patients were operated on for AAAD. Patients were divided into two subgroups: the cohort of patients operated on from January 1998 until December 2003 (without ASCP) (P1998-2003, n=64) and the cohort operated on from January 2004 until December 2008 (with ASCP)(P2004-2008, n=78).
The difference in hospital mortality was statistically significant (P1998-2003: 42.2%; P2004-2008: 14.1%, p<0.0005). Survival rates were 51.6±6.2% vs. 75.1±5.5% and 45.9±6.2% vs. 69.7±7.3% for one and four years, respectively (p=0.001). Multivariate logistic regression analysis revealed that ASCP was the only independent protective factor of hospital mortality (p=0.047).
In patients operated on for AAAD, antegrade selective cerebral perfusion with moderate hypothermia is a significant factor in decreasing hospital mortality.

ABSTRACT: The impact of meteorological conditions on the occurrence of various cardiovascular events has been reported internationally. Data about the Dutch situation are limited.
We sought to find out a correlation between weather conditions and the incidence of major acute cardiovascular events such as type A acute aortic dissection (AAD), acute myocardial infarction (AMI) and acutely presented abdominal aortic aneurysms (AAAA).
Between January 1998 and February 2010, patients who were admitted to our hospital (Catharina Hospital, Eindhoven, the Netherlands) because of AAD (n = 212), AMI (n = 11389) or AAAA (n = 1594) were registered. These data were correlated with the meteorological data provided by the Royal Dutch Meteorological Institute (KNMI) over the same period.
During the study period, a total number of 11,412 patients were admitted with AMI, 212 patients with AAD and 1593 patients with AAAA. A significant correlation was found between the daily temperature and the number of hospital admissions for AAD. The lower the daily temperature, the higher the incidence of AAD (p = 0.002). Lower temperature was also a predictor of a higher incidence of AMI (p = 0.02). No significant correlation was found between daily temperature and onset of AAAA.
Cold weather is correlated with a higher incidence of AAD and AMI.
