The exact incidence of chronic total occlusions (CTOs) during routine coronary angiography is not well defined. It has been reported in the literature that CTOs are encountered in approximately one-third of diagnostic cardiac catheterizations.1 Anoth…
Successful recanalization and percutaneous revascularization of coronary arteries with chronic total occlusions (CTO) is one of the last frontiers in percutaneous coronary interventions (PCI). Successful CTO treatment is associated with reduced angin…
Percutaneous coronary intervention (PCI) offers an alternative form of therapy for patients considered to be at high risk for coronary artery bypass graft surgery (CABG). PCI is associated with substantial morbidity and mortality in the presence of s…
Coronary artery perforation (CAP) is an uncommon, yet potentially devastating, complication of percutaneous coronary interventions (PCI).1 Early reports of this catastrophic complication date back to the early 1980s.2 In a recent review of 6,245 pati…
Case Report. A 66-year-old female was admitted in March 2005 with non-ST-segment elevation myocardial infarction (NSTEMI). She had a prior history of hypertension, dyslipidemia and paroxysmal supraventricular tachycardia (SVT). Her coronary angiogram…
Transcatheter closure of ventricular septal defects has emerged as an attractive therapeutic modality, with excellent procedural and intermediate hemodynamic outcomes. While experience with this technique is relatively limited, longerterm follow up i…
Chronic total occlusion (CTO) represents 10–20% of all angioplasty cases and remains a challenge for interventional cardiologists.1–3 CTOs are associated with significant angina, impaired left ventricular function and poor long-term outcomes.4 Althou…
Chronic total occlusions (CTOs) present one of the most challenging obstacles to interventional cardiologists in the current era. Technical difficulties associated with percutaneous coronary intervention (PCI) of CTOs are reflected by lower success r…
During angiography, when the saphenous vein graft (SVG) bypassing a chronic total occlusion (CTO) in a coronary artery is found to be patent without significant obstructive disease, conventional wisdom would suggest adequate distal perfusion supply a…
Thrombus is highly prevalent in patients with peripheral arterial disease, particularly those with recent symptoms and occluded or subtotally occluded vessels. In a prospective registry of 17 consecutive patients with recent (< 6 months) symptoms…
