An internal thoracic artery pseudoaneurysm associated with an arteriovenous fistula to the innominate vein is a very rare complication after implantation of a cardioverter-defibrillator. We report the successful endovascular management of this unusual complication.

The radial approach during percutaneous coronary intervention (PCI) has been reported to reduce the incidence of bleeding complications. However, the radial approach still accounts for <10% of procedures worldwide and only 1% in the United States. Our objective was to compare the effect of radial versus femoral vascular access on the time to reperfusion, incidence of bleeding complications, and overall clinical outcomes in the setting of primary PCI.

Objective: To report the evolution of demographics, treatment and outcome of patients admitted to a tertiary coronary care unit (CCU) over a 17-year period.
Methods: A prospective database of 18,719 patients admitted from April 1986 to March 2003 in a 21-bed CCU was analyzed.
Background: Percutaneous coronary intervention induces an early inflammatory reaction. The intensity of such a reaction as measured by high-sensitivity C-reactive protein has been correlated with recurrent ischemic events, but its association with restenosis remains uncertain.
Objectives: To characterize the type and duration of the postangioplasty inflammatory reaction and to identify new inflammatory markers correlating with restenosis.
Although stent under-deployment (SU) has been associated with increased risk of in-stent restenosis, little data have been reported on the incidence of SU in patients presenting with clinical in-stent restenosis. In 59 patients referred for vascular brachytherapy and showing angiographic in-stent restenosis, we sought (1) to determine the incidence of SU using standard intravascular ultrasound (IVUS) criteria (2) to evaluate the effects of repeat angioplasty on further stent expansion. Stented length was 32+/-17 mm and diameter stenosis was 75+/-14%.

Echocardiography was a key element in establishing the diagnosis of this rare anomaly, which is often congenital but has also been reported as acquired or traumatic in origin.

The need for repeat PCI has been significantly reduced in patients since the advent of vascular brachytherapy. In-stent restenosis resulting in bifurcation presents even more of a challenge.

Methods And Results: Thirty patients treated with post-percutaneous transluminal coronary angioplasty (PTCA) VBT with Sr90 underwent clinical and angiographic follow-up at 6 and 24 months.
Background: The antioxidant probucol reduced coronary restenosis in the MultiVitamins and Probucol (MVP) trial by improving vascular remodelling. Whether calcification limits the extent of adaptive vessel enlargement is not known.
Objective: To determine whether plaque composition at the dilated site affects probucol-induced vascular remodelling after angioplasty.
