Late Incomplete Apposition and Coronary Artery Aneurysm Formation following Paclitaxel-Eluting Stent Deployment: Does Size Mat

 

Case Presentation. A 43-year-old female with stable angina pectoris underwent stenting of a 99% stenosis in a small left anterior descending coronary artery (Figure A). In an uneventful procedure, a 2.25 x 8 mm Taxus® Express paclitaxel-eluting stent (Boston Scientific Corp., Natick, Massachusetts) was deployed at 12 atm, achieving an optimal angiographic result, with slight oversizing of the stented segment in relation to the reference vessel (Figure B). Two months later, angiography revealed localized CAA formation within t



Protein-Losing Enteropathy following the Fontan Operation

Protein-losing enteropathy (PLE) may be defined as excessive loss of proteins across the intestinal mucosa and is due to either a primary gastrointestinal abnormality or secondary to cardiac disease. Initial reports of PLE secondary to cardiac disease, namely, congestive heart failure,1 constrictive pericarditis2,3 and myocarditis4 were published in the early 1960s. The association of PLE with high superior vena caval pressure secondary to an obstructed Mustard baffle5 and superior vena cava-toright pulmonary artery anastamosis (Classical Glenn Op

“Alle Ding’ sind Gift und nichts ohn’ Gift; allein die Dosis macht, dass ein Ding kein Gift ist”

[ All things are poison and nothing is without poison; only the dose permits something not to be poison ] – Paracelsus

Although he was born Phillip von Hohenheim, he later changed his name to Philippus Theophrastus Aureolus Bombasticus von Hohenheim, and called himself Paracelsus (literally: equal to or greater than Celsus — a Roman encyclopedist known for medical writings). No, he was not a 15th century version



Preserving Left Ventricular Function during Percutaneous Coronary Intervention

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’s face it, most of us don't consciously plan to preserve myocardium at all costs when we are confronted with a difficult bifurcation lesion. To the battle-ravaged ventricle that has endured the torment of hypertension, diabetes, a few previous non-ST-elevation myocardial infarctions (NSTEMIs), along with the regular pulses of



Stents in the Successful Management of Protein-Losing Enteropathy after Fontan

Protein-losing enteropathy (PLE) is a serious, and if not treated, fatal complication of the Fontan-cavopulmonary anastomosis procedure.1 It has been suggested that creation of a fenestration may prevent2 and treat3,4 PLE in this setup. Other therapeutic modalities have included the use of heparin,5 spironolactone,6 steroids and angiotensin-converting enzyme inhibitors with variable success.6 Transcatheter interventional procedures have been thought to be beneficial in the treatment of PLE, but experience in this modality is



Reduction in Myocardial Infarct Size by Postconditioning in Patients after Percutaneous Coronary Intervention

Timely reperfusion is the most effective intervention to protect the heart from myocardial infarction resulting from coronary occlusion. However, experimental studies and clinical observations have provided strong evidence in support of the existence of reperfusion-induced myocardial injury. Reperfusion injury initiates a series of adverse events that offset the benefits intended by implementing early reperfusion.1–4 Protection elicited by pharmacological treatment applied briefly at the onset of reperfusion may be observed acutely, but may not be evident when the duration



Clopidogrel Loading Doses and Outcomes of Patients undergoing Percutaneous Coronary Intervention for Acute Coronary Syndromes

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 percutaneous coronary intervention (PCI) is planned and who are not at high risk for bleeding.1,2 Although the guidelines indicate that a loading dose of 300 mg to 600 mg can be used when rapid onset-of-action is required, followed by a maintenance dose of 75 mg/day, the evidence supporting the efficacy of clopidogrel in preventing cardio



“Fogarty-Like” Removal of Large Coronary Thrombus

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 at the occlusion site, or trap embolic materials, respectively. The effect of thrombectomy devices on myocardial perfusion have been conflicting: some studies1–3 show a benefit, while others suggest a detrimental effect on myocardial salvage resulting in increased infarct size.4 Specifically, unrestricted use of dista
