Abstract

We report on a case of a false aneurysm at the access site after transapical aortic valve replacement. Although this is not the first case report about this issue, our case emphasizes the importance of follow-up echocardiography after transapical aortic valve replacement that focuses not only on prosthesis function, but also on detecting probable complications of the surgical access site.

Abstract

Carotid sinus reactions (CSR), defined as asystole >/= 3 sec and hypotension (systolic blood pressure ostial > isolated internal carotid artery; P < 0.001). The other independent predictors were presence of contralateral stenosis (P < 0.02), length of stenosis (P < 0.03), and balloon-to-artery ratio (P < 0.02). Occurrence of CSR was unrelated to periprocedural cerebral or cardiovascular complications (7.1% vs. 9.5%; NS). We conclude that CSR occurs frequently (40%) during CAS. Bifurcation location of stenosis is the most important predictor of CSR. CSR does not increase the risk of periprocedural complications., (Copyright 2003 Wiley-Liss, Inc.)

Abstract

Background and Purpose: Abciximab has been shown to significantly reduce thromboembolic complications of coronary artery stenting. A prospective, randomized study was performed to test whether abciximab has comparable beneficial effects in carotid artery stenting., Methods: Seventy-four consecutive patients undergoing elective stenting of the carotid artery were included in the study. Standard antithrombotic medication consisted of aspirin, clopidogrel, and heparin. In addition, half of the patients received an abciximab bolus of 0.25 mg/kg body weight given prophylactically before the intervention., Results: The procedure was successful in all but 1 patient. In patients receiving abciximab, ischemic complications consisted of 4 transient ischemic attacks, 1 minor stroke, 1 nonfatal major stroke, and 1 fatal stroke caused by cerebral hemorrhage. In the control group, 2 transient ischemic attacks and 1 major nonfatal stroke occurred. In summary, the total number of periprocedural ischemic events was 7 (19%) in the abciximab group and 3 (8%) in the control group. Nonischemic complications consisted of 1 inguinal hematoma requiring blood transfusions in each group., Conclusions: Abciximab bolus given prophylactically before elective carotid artery stenting does not reduce ischemic complications.
