Trifurcating coronary artery disease is a complex atherosclerotic process involving the origin of one or more of three side branches (SB) arising from a main coronary artery vessel or trunk (MT), with or without involvement of the MT itself. Percutan…
Carotid artery stenting (CAS) is now widely utilized as a less invasive alternative to carotid endarterectomy for the prevention of stroke caused by extracranial bifurcation carotid artery stenosis. The procedure involves diagnostic angiography, the…
Incidence Coronary angiography has been and currently remains the gold standard for the diagnosis of coronary artery disease. It is an invasive procedure and is thus associated with various risks such as vascular and hemodynamic complications, contra…
A 70-year-old male presented with left buttock claudication. Diagnostic angiography showed a 90% left external iliac artery stenosis (Figure 1A). The left external iliac artery lesion was crossed with a 0.035 Storq guidewire (Cordis Corp., Miami, Flo…
Coronary air embolism is a recognized complication of cardiac catheterization occurring in 0.1–0.3% of cases.1 Sequelae range from various clinically-insignificant events to an acute coronary syndrome and death.2 The possible mechanisms of the introd…
Chronic total occlusions (CTOs) are common and are found in approximately one-third of patients with significant coronary disease who undergo angiography.1 Previous studies have demonstrated the importance of revascularization of CTOs, with improveme…
Recently, it was reported that aggressive and optimal directional coronary atherectomy (DCA) using intravascular ultrasound (IVUS) can be performed with favorable outcomes.1–4 The benefit of DCA is thought to be the debulking of plaques in the main v…
Electrocautery has long been described to generate electromagnetic interference (EMI) and oversensing by implanted pacemakers and defibrillators. Electrocautery is commonly used during surgical procedures involving implantation and explantation of pa…
Secundum atrial septal defect (ASD) is the most common congenital heart defect first diagnosed in adults, even late in life,1 and it may be successfully closed percutaneously. Patent foramen ovale (PFO) is a remnant of fetal circulation present in ab…
The initial interest in the late 1980s in balloon aortic valvuloplasty (BAV) for adults with calcific aortic stenosis (AS) was subsequently tempered by multiple studies demonstrating high rates of restenosis and lack of a favorable impact on long-ter…
