Direct communication between the right pulmonary artery and the left atrium is an unusual variation of a pulmonary arteriovenous fistula. In fact, there are only about 50 cases reported in the literature.1 This is one condition in which clinical exam…
To the Editor: The angiographic finding of noncritical coronary stenoses in the setting of acute coronary syndrome and even myocardial infarction has been well described. One potential etiology is Prinzmetal’s angina or coronary spasm.1 More recent J…
Pseudoaneurysm formation is a rare complication following carotid endarterectomy (CEA), with an incidence of less than 1% of cases.1 Treatment of this complication is challenging. The current standard of care is some form of repair rather than conser…
Takayasu’s arteritis (TA) is a chronic inflammatory large-vessel disease of unknown etiology involving the aorta, its major branches and the pulmonary arteries.1,2 Resultant mixed areas of stenosis, occlusion, thrombosis and/or dilatation may cause a…
Coronary arterial anomalies occur in approximately 1% of the population, without other congenital cardiac malformations.1 The incidence of anomalous origin of the right coronary artery out of the right sinus of Valsalva ranges from under 0.01–0.09%.…
Successful recanalization of chronic total occlusion (CTO) improves left ventricular function1 and survival.2 There are, however, several difficulties with percutaneous coronary intervention (PCI) for CTO (CTOPCI). Failure to cross the occlusive lesi…
Early restoration of infarct-related artery (IRA) blood flow and myocardial perfusion in patients with acute ST-segment elevation myocardial infarction (MI) is linked with preservation of left ventricular function, myocardial salvage and a reduction…
Women have been shown historically to have a greater risk of complications than men following invasive procedures.1–5 The increased incidence of complications in women appears to occur independently of other factors known to influence the incidence o…
There is extensive literature demonstrating a disturbingly higher mortality rate, intraprocedural coronary artery injury rate and periprocedural vascular complication rate in women versus men. The disparity has been partially explained by more comorb…
Unprotected left main coronary artery (LMCA) is one of the most challenging lesion subsets for interventional cardiologists, and is still considered a strict surgical indication as long-term results of recent randomized trials are awaited. Although n…
