The Function of the Left Ventricle After Complete Multivessel One-Stage Percutaneous Coronary Intervention in Patients With Acut
Acute ST-segment elevation acute myocardial infarction (STEMI) is one of the main causes of morbidity, hospitalization and consequently increases healthcare costs. The primary goal of therapy in STEMI is to regain patency of the culprit vessel (TIMI…
Outcome in patients with abnormal baseline serum creatinine (>= 1.5 mg/dl). Follow-up serum creatinine was unchanged in 53%, improved in 18%, and worsened in 29% of patients at a mean follow-up of 21 ± 11 months.
Stabilization of Renal Function Following Renal Artery Stent Revascularization
The progressive nature of atherosclerotic renal artery stenosis is now well recognized.1–8 Observational data suggests that untreated renal artery stenosis can lead to progressive hypertension, renal insufficiency, and increased mortality.6,9–11 The…
A Prospective, Randomized Trial to Determine the Early and
Late Reactions After the Use of Iopamidol 340 (Niopam‚Ñ¢)
and Iobitri
Intravascular contrast is a prerequisite for modern invasive cardiology. The contrast agents used for various procedures have become increasingly safe in recent years. Compared to ionic agents, the modern non-ionic contrast agents are fairly well tol…
Hinge point of the popliteal artery.(A) Stent in the popliteal artery. (B) The hinge point of the popliteal artery impedes the normal outflow through the stent during knee flexion.
Flexions of the Popliteal Artery: Dynamic Angiography712
EDITOR’S NOTE: This article by Diaz et al. contains extremely valuable information. The importance of assessing the “dynamic anatomy” of the popliteal artery (and other vessels) was only recently appreciated as a result of developments with endovascu…
Right anterior oblique (RAO) view of the right coronary artery (RCA) prior to percutaneous intervention. Note the presence of two parallel stenotic-appearing channels in the mid-RCA.
Which Is The True Channel?
Case report. A 70-year-old woman with a history of smoking, hypertension and hyperlipidemia was referred for evaluation of exertional angina that had developed over the preceding 6 months. Thirteen years earlier, she had undergone balloon angioplasty…
Directional Atherectomy With the SilverHawk Plaque Excision
Device in the Treatment of a Proximal Subclavian-Vertebral
Artery
Subclavian artery stenoses can, in patients who have undergone previous left internal mammary artery (LIMA) to left anterior descending (LAD) bypass grafting, lead to coronary-subclavian steal syndrome (CSSS).1 This occurs when a proximal subclavian…
(B) Direct stenting was performed at 17 atm of pressure, but the stent was not completely expanded at the middle segment of the lesion (arrow).
Successful Management of a Resistant, Focal Calcified Lesion Following Direct Coronary Stenting With a Cutting Balloon
Direct stenting is a feasible and safe technique, which may reduce the procedure time, cost and radiation exposure as well as result with less vessel injury. However, it is not suitable for coronary lesions with excessive calcification, severe proxim…
This figure shows the total occlusion of the right coronary artery (LAO 30° projection).
Management of Right Coronary Artery Perforation During Percutaneous Coronary Intervention with Polyvinyl Alcohol
Foam Embolizat
Coronary artery perforation is a rare but potentially catastrophic complication of percutaneous coronary intervention (PCI).1–3 The availability of polytetrafluoroethylene (PTFE) covered stents made a significant impact on the treatment of this compl…
Interventional and Peripheral Vascular Procedures Using Contrast Management: Tips and Techniques
The following special CME section is underwritten through an educational grant from Bracco Diagnostics The first cardiac catheterization reported occurred in 1929 in Germany, performed by Dr. Werner Forssmann.1 After anesthetizing his own arm and pe…
Treatment of Coronary Artery Disease in Dialysis Patients with Sirolimus-eluting Stents: 1-year Clinical Follow-up of a Consecut
In this preliminary series, sirolimus-eluting stent implantation appeared safe and effective for the treatment of dialysis patients with coronary artery disease. Dialysis patients are well known to be a high-risk population for cardiovascular morbidi…
