for left ventricular (LV) study and elastic functions of aorta. Carotid- intima media thickness (CIMT) was measured by using sonogra- phy. The patients were assessed for hypertension by using ABPM. As indirect marker of arterial sti ness, pulse wave velocity (PWV) and augmentation index (aix@75) parameters were recorded by using ABPM/arteriograph. In addition, we compared data from 9 patients who were common between our study and a similar study conducted in 2011.
Findings: interventricular septum thickness, diastolic LV posterior wall thickness, systolic LV posterior wall thickness, LV mass and LV mass index values were found to be signi cantly higher in the patient group. ABPM revealed, mean systolic pressure, daytime systolic pres- sure, mean arterial pressure, daytime mean arterial pressure, PWV and cardiac output values were found to be signi cantly higher in the patient group than control group. No signi cant di erence was detected in aortic sti ness, distensibility and strain values between groups. CIMT was found to be signi cantly higher in the patient group. No signi cant correlation was detected among CIMT, LVMI, aix@75 and PWV values. In the comparison of 2 studies, elevation rate on months 0, 1 and 6 was 33% in the previous study while this rate was decreased to 11% in our study when assessed according to LVMass Z score.
Conclusions: It was shown that hypertension incidence and risk for cardiovascular diseases were greater than those in healthy popula- tion even AC is corrected. This suggests that AC is a part of general- ized vasculopathy and that use of these measurements in follow-up of patients with AC can be helpful to predict risks.

Background: Access via percutaneous carotid artery (CA) methodol- ogy is increasingly common, supplanting traditional femoral arterial access. Late incidence of CA stenosis following percutaneous access is unreported. We performed a retrospective review of patients receiving CA access to assess late CA stenosis and patency.
Methods: We reviewed all CA access cases and any follow up catheter- izations that included angiography from 2012 to 2016. We reviewed access site complications, follow up ultrasound imaging of the CA, and presence of late CA stenosis on follow up angiography.
Results: During the study period, there were 48 total CA catheter- izations in 41 patients – carotid access was repeated in 6 patients and twice in 1 patient. Median age at CA access was 22 days (range 1-1636) with a weight of 3.1kg (range 1.6-15.7). The majority of pro- cedures were for ductus arteriosus (PDA) stenting (26/48; 54%) or BT shunt (14/48; 29%) interventions. Median duration of CA access was 42 minutes with time to hemostasis of 9 minutes. Acute post-cath CA ultrasound demonstrated complete luminal patency except in 2 cases (4%) where a small, non-occlusive thrombus was noted and was then treated with enoxaparin. Both patients had subsequent full
