ABSTRACT: Coronary stent infection is exceedingly rare despite the widespread use of percutaneous coronary intervention (PCI). The utilization of drug-eluting stents (DES) may have a higher theoretical risk of infection due to their local immunosuppr…
The introduction of coronary artery stents in the early 1990s reduced the early and late reocclusion rates of symptomatic coronary artery stenoses after balloon angioplasty. Nevertheless, coronary stent occlusion by thrombosis may occur, even in pati…
Self-expandable stent fracture may occur when the stent is implanted in peripheral arteries near or at flexion points.1 However, stent squeeze is quite rare, especially early after implantation. We report a case of a patient with an occlusive resteno…
Coronary stent infection is a rare but previously reported complication of coronary artery stenting procedures (CAS).1–13 In the few cases reported in the literature, patients have presented within days to weeks of stent implantation with fever, and…
Cardiogenic shock complicating myocardial infarction carries a poor prognosis. Data regarding percutaneous intervention in the very elderly with cardiogenic shock is sparse.1 Age is an independent risk factor for worse outcome with cardiogenic shock.…
The performance of transesophageal echocardiography (TEE) has become common in the routine assessment of patients who have had transient ischemic attacks (TIAs) or stroke. As part of the TEE evaluation, agitated saline is usually injected through a p…
In patients undergoing emergency percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI), several thrombectomy and distal protection devices have been evaluated in order to either remove thrombus and plaque components…
Current American College of Cardiology/American Heart Association guidelines for the treatment of unstable angina (UA) and non-ST-segment elevation myocardial infarction (NSTEMI) recommend initiation of clopidogrel treatment in patients for whom perc…

Perhaps we interventionists should be more aware than we currently are of our patients’ left ventricular (LV) function or what angioplasty might do to that LV function. I am not suggesting that we don’t attach importance to this vital detail. But let…
