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…
Standard therapy for cryptogenic stroke in the setting of patent foramen ovale (PFO) includes antiplatelet medications and long-term anticoagulation with warfarin. Oral anticoagulation increases the risk of bleeding complications and may not prevent…
The discipline of catheter-based closure of patent foramen ovale (PFO) is still in its “childhood”. Ushered in by the seminal paper from Bridges et al in 1992,1 it is still hampered by amateurism, ghosts of old misconceptions, apprehension about new…
Percutaneous coronary intervention (PCI) in bifurcations represents 15–18% of all lesions treated1 and has traditionally been associated with more complexity and restenosis. It has been demonstrated with bare-metal stents (BMS) that the strategy of p…
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…
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…
There has been growing interest in transradial coronary procedures due to the rare incidence of complications at this puncture site, elimination of the need to limit the patient’s activity and the possibility of early patient discharge.1,2 Furthermor…
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…
