A Case of Hemolysis after Percutaneous Ventricular Septal Defect
Closure with a Device
Hemolytic anemia related to intracardiac prosthetic materials is well recognized. It was first reported by Sayed et al, when a Teflon ASD patch produced intravascular hemolysis.1 Since then, intravascular hemolysis has been described after postoperat…
IVUS-Guided Evaluation and Percutaneous Intervention in an
Anomalous Left Main Coronary Artery
Case Report. A 42-year-old asymptomatic female with longstanding Type-1 diabetes and secondary chronic renal failure underwent evaluation for potential kidney-pancreas transplantation. A screening treadmill myocardial perfusion scintigraphy study rev…
Percutaneous Treatment of Catheter-Induced Dissection of the
Right Coronary Artery and Adjacent Aortic Wall
Acute aortic dissection during coronary arteriography or percutaneous coronary intervention is quite rare,1,2 but is a feared complication. Patients in this clinical setting may have a potential risk for acute myocardial infarction (MI) requiring eme…
An Unusual Congenital Coronary Anomaly: Origin of the Left
Circumflex Coronary Artery from a Right Coronary Artery
Arising fro
Congenital coronary anomalies are relatively uncommon, with a prevalence varying from 0.3% of autopsy series1 to 1.2% of angiographic studies.2 Such anomalies may occur in several anatomical arrangements, with different clinical significance, which h…
The Value of Intravascular Ultrasound-Facilitated Internal Carotid
Artery Stenting in a Patient with Heavily Calcified and
Amb
Stenosis of the internal carotid artery is responsible for 10–20% of all strokes or transient ischemic attacks. Percutaneous transluminal carotid artery stenting (CAS) is a promising new treatment option for carotid artery stenosis. These procedures…
PCI of the Right Coronary Artery via or under Struts of Stents
Protruding into the Aorta
The ostium of the right coronary artery (RCA) is not a tubular structure . Hence, sizing, positioning and flaring the stent in the ostium of the RCA demands considerable skill, and occasionally will not yield optimal results. At least mild protrusion…
Visualization of a Cluster of Embolic Particles Causing
Angiographic No-Reflow during Percutaneous Coronary
Intervention
Embolization of thrombi and plaque components liberated by balloon inflation has been speculated1 to cause angiographic no-reflow during percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Embolic particles in…
Similar Case of Anomalous Origin
I read the article regarding a single coronary artery by Namboodiri et al,1 published in the April 2007 issue of the Journal of Invasive Cardiology, with great interest. However, the authors missed referencing a few important publications related to…
Carotid Artery In-Stent Restenosis Resolved with Drug-Eluting Stenting
We were pleased to have our Clinical Decision Making article “Carotid Artery In-Stent Restenosis in a Patient with Contralateral Total Occlusion, Resolved with Drug-Eluting Stenting” published in the June 2007 issue of the Journal of Invasive Cardiol…
Difficult Anatomies: Use Three Hands
Today’s interventional cardiologist is armed with a vast array of devices for treatment of increasingly difficult lesions. Inhospitable anatomies previously considered suitable only for surgical therapy are now frequently accessible with modern tools…
