Case ReportsLate complete atriovenous block after percutaneous closure of a perimembranous ventricular septal defect.
Percutaneous closure of a perimembranous ventricular septal defect (VSD) is an alternative to surgical closure. Complications include arrhythmias and in particular early postoperative complete atrioventricular (AV) block. ⋯ The first patient experienced syncope, while the second one was completely asymptomatic. Both subjects underwent endocardial ventricular pacemaker implantation.

Feasibility and safety of transbrachial approach for patients with severe carotid artery stenosis undergoing stenting.
Although sporadic successful cases using the transradial approach (TRA) for carotid stenting have been reported, the safety and feasibility of carotid stenting using either TRA or a transbrachial approach (TBA) have not been fully investigated. Recently, we have developed a safe and feasible method of TRA for cerebrovascular angiographic studies. This study investigated whether a TBA approach using a 7-French (F) Kimny guiding catheter for carotid stenting is safe and feasible for patients with severe carotid stenosis. ⋯ The procedure was successful in all patients. No neurological or vascular bleeding complications were observed and all patients were discharged uneventfully. The TBA for carotid stenting was safe and effective, providing a last resort for patients unsuited to femoral arterial access and surgical intervention.

Case ReportsPerforation complicating carotid artery stenting: the use of a covered stent.
Carotid artery angioplasty and stenting has emerged as an effective strategy for the treatment of significant carotid artery stenosis. Perforation during carotid artery stenting is a very rare potential complication of the procedure. We describe a case of carotid artery perforation that occurred during postdilation of the carotid artery stent. In our case this potentially serious complication was successfully treated with a covered stent-graft.
