Primary Percutaneous Coronary Intervention for ST-Elevation Myocardial Infarction in a Patient with a Single Coronary Artery Arising from the Right Aortic Sinus
ABSTRACT: We report the first case of primary percutaneous coronary intervention (PPCI) in a patient with a single coronary artery arising from the right aortic sinus. With the increasing availability of PPCI, more patients with coronary artery anoma…
A Pain in the Leg Following Angiography
ABSTRACT: This case illustrates a complication following deployment of the Angioseal® vascular closure device after routine angiography. The AngioSeal device is a percutaneous, bioabsorbable, collagen-based hemostatic plug deployed to seal the arteri…
Successful Use of an Extra-Long Hydrophilic-Coated Sheath in Enlarged Aorta to Overcome Extreme Tortuosity of Right Subclavian Artery Via Transradial Approach During Coronary Angiography
ABSTRACT: The transradial approach (TRA) has gained popularity in recent years mainly because of the significantly decreased access-site complications and the greater patient comfort it offers. In this paper, we describe the successful use of an extr…
Successful Percutaneous Implantation of an Aortic Valve Stent Prosthesis in a Patient with a Mechanical Mitral Valve
ABSTRACT: Percutaneous aortic valve replacement represents a minimally-invasive alternative to open heart valve replacement in high-risk patients. Interventional procedures are used in an increasing number of patients and indications are broadened as…
Iatrogenic Dissection of the Anomalous-Origin Right Coronary Artery and Left Sinus of Valsalva
ABSTRACT: Anomalous right coronary artery arising from the left sinus of Valsalva is a rare congenital abnormality. Percutaneous coronary intervention of the anomalous-origin right coronary artery can be challenging. Iatrogenic aortocoronary dissecti…
Ruptured-Plaque-Like Appearance of Restenotic Tissue Following Sirolimus-Eluting Stent Implantation: An Optical Coherence Tomography Case Study
ABSTRACT: A 57-year-old man was admitted for exertional angina pectoris. Coronary angiography showed a 99% stenosis in the left circumflex artery. A sirolimus-eluting stent was deployed in the culprit lesion and excellent angiographic results were ob…
Enhancing Back-up Support During Difficult Coronary Stent Delivery: Single Center Case Series of Experience with the Heartrail II Catheter
ABSTRACT: Background. Despite continued advances in creating lower profile intra-coronary balloons and stents, technical difficulties with stent deliverability are frequently encountered. Recent advances in catheter design have yielded soft ended atr…
Use of the GuideLiner Catheter for the Treatment of a Bifurcational Total Occlusion of the Native Left Anterior Descending Artery through a Tortuous Composite Venous Graft
ABSTRACT: Difficulty in stent delivery is frequently encountered in cases of tortuous or calcified coronary arteries. Chronic total occlusion interventions often require extra back-up that may not be adequately provided by guiding catheters, even the…
“Bilateral Knuckle” Technique and Stingray Re-Entry System for Retrograde Chronic Total Occlusion Intervention
ABSTRACT: We report a novel technique for retrograde chronic total occlusion intervention, in which the lesion is crossed by forming and advancing a “knuckle “in both the antegrade and retrograde guidewire, followed by reentry in the true lumen by us…
The Sword of Damocles: An Illustrative Example of the Life-Saving Effect of the Collateral Circulation
ABSTRACT: There is an ongoing debate on the effective importance of the collateral network, especially in the current era, where most patients with significant coronary artery disease are revascularized, be it percutaneously or surgically; thus, peop…
