RCA in RAO view. There are thin septal collaterals (arrows) to the LAD and collaterals from the PDA to the distal LAD.
Agenesis of the Left Main Stem: A Rare Cause of Sudden Cardiac Death
Case Report. A 32-year-old male suffered cardiac arrest out of hospital, was successfully resuscitated and transferred to our tertiary cardiac unit where we performed coronary angiography. Despite multiple attempts, the left main coronary artery (LMC…
Transvenous Pacing Causing Tamponade in Patients Receiving Glycoprotein IIb/IIIa Inhibitors for Percutaneous Coronary Interventi
A backup temporary pacing wire is often used in patients with heart block undergoing cardiac catheterization and percutaneous coronary intervention (PCI). It is particularly recommended for any patient undergoing rotational atherectomy or rheolytic t…
Transesophageal echocardiography (TEE) of the prosthetic mitral valve with left atrium adjacent to the transducer. (A) A 6 mm defect is present (black arrow) adjacent to the mitral valve sewing ring on the lateral aspect of the left ventricle near the lef
Paravalvular Mitral Regurgitation Treated with an Amplatzer Septal Occluder Device: A Case Report and Review of the Literature
Case Report The patient is a 62-year-old male with a past medical history significant for hypertension, hyperlipidemia and coronary artery disease. In October 2004, he developed congestive heart failure and was diagnosed with severe mitral regurgitat…
1. Coronary angiogram shows that the first obtuse marginal (OM) branch is totally occluded at the ostium (A, RAO caudal view). The OM branch was successfully recanalized and a sirolimus-eluting stent was implanted (Cypher 3.0 x 23 mm) (B). The stent was p
Fractured DES with a Patent Coronary Artery: Clinical Implications
Drug-eluting stents (DES) have, for the most part, replaced bare-metal stents (BMS) as a safe and effective therapeutic modality for treating coronary stenosis. Post-DES restenosis with sirolimus-eluting stents (SES) or paclitaxel-eluting stents (PES…
Baseline angiography of the left lower limb, disclosing long and total occlusions of the anterior tibial, dorsalis pedis, and posterior tibial arteries, critical stenoses of the peroneal artery, with a patent plantar branch (A and B show the proximal tra
Pedal-Plantar Loop Technique for a Challenging Below-the-Knee Chronic Total Occlusion: A Novel Approach to Percutaneous Revascul
Arterial revascularization by means of percutaneous transluminal angioplasty (PTA) is being increasingly used for the treatment of patients with severely symptomatic peripheral artery disease (i.e., those with critical limb ischemia). This phenomenon…
Demographic, clinical and procedural characteristics of each study group.
Bivalirudin versus Heparin Plus Glycoprotein IIb/IIIa Inhibitors in Drug-Eluting Stent Implantations in the Absence of Acute Myo
Bare-metal stents (BMS) lower the risk of restenosis and the need for repeat coronary revascularization compared to balloon angioplasty alone.1 The introduction of drug-eluting stents (DES) has further markedly decreased angiographic restenosis rates…
Bivalirudin and DES: A PCI Strategy that Pays
The choice of anticoagulant in patients undergoing percutaneous coronary intervention (PCI) has been the subject of intense investigation over the past decade. Ever since anticoagulation with heparin was observed to be an essential treatment in patie…

Scanning Electron Microscopic Analysis of Defects in Polymer Coatings of Three Commercially Available Stents: Comparison of Biod
Coronary stenting has demonstrated a consistent ability to reduce restenosis rates compared with percutaneous “plain old” balloon catheter angioplasty. However, in-stent restenosis has long remained the major limitation of coronary stenting. Recent r…
VB-stenting for trifurcation disease. A 9 Fr guide is utilized. After wiring the 3 branches, kissing balloon (KB) dilatation is done as needed. The MB and SB1 are stented using the V-stenting technique. KB is then performed on all 3 branches as needed.
Long-Term Outcomes in Treating Left Main Trifurcation Coronary Artery Disease with the Paclitaxel-Eluting Stent
Left main (LM) trifurcation coronary stenting is a challenging and complex percutaneous procedure that has been reported in small series and case reports.1–5 Typically, this disease is treated surgically, but with the advent of drug-eluting stents (D…
Radial artery larger than ulnar (antero-posterior film, palm facing upwards). (A) Brachial artery; (B) small recurrent radial; (C) ulnar; (D) small recurrent ulnar; (E) Radial and ulnar arteries overlayed; (F) common interosseous; (G) radial; and (H) smal
Transulnar Access for Coronary Angiography and Intervention: An Early Review to Guide Research and Clinical Practice
Percutaneous coronary intervention and coronary angiography are increasingly performed via radial artery access after resurrection of this route by Campeau in 1989.1 The reasons for this are reduced local complication rates compared to procedures usi…
