Usefulness of the SafeCut Dual Wire PTCA Catheter for the
Treatment of Calcified Lesions
In-stent restenosis has long remained the major limitation of coronary stenting. Recent randomized trials have shown that the use of drug-eluting stents (DES) markedly reduce the risk of in-stent restenosis following treatment of de novo lesions,1–4…
Percutaneous Coronary Intervention of Chronic Saphenous Vein
Graft Occlusion: A Potential New Paradigm
Case PresentationA 69-year-old male with a history of hypertension, hyperlipidemia, s/p coronary artery bypass graft in 1994 (saphenous vein graft [SVG] to the right coronary artery [RCA], SVG to the diagonal branch, SVG to the obtuse marginal artery…
Spontaneous Dissection of the Left Main Coronary Artery Treated
with Percutaneous Coronary Stenting
Spontaneous coronary artery dissection (SCAD) is an unusual cause of acute myocardial ischemia, with approximately 300 cases reported in the literature.1,2 It is often fatal and is mostly recognized at postmortem examination in young victims of sudde…
Microcoil Embolization of Distal Coronary Artery Perforation
without Reversal of Anticoagulation: A Simple, Effective Approach
Coronary artery perforation is an infrequent but serious complication of percutaneous coronary intervention (PCI), occurring in some 0.3–0.6%.1–4 The classification by Ellis et al1 describes perforation as type I, an extraluminal crater without extra…
Use of Tandem Heart‚Ñ¢ as a Temporary Hemodynamic Support
Option for Severe Pulmonary Artery Hypertension Complicated
by Cardiog
The TandemHeart™ device (Cardiac Assist, Inc., Pittsburg, Pennsylvania), a percutaneous nonpulsatile centrifugal left ventricular (LV) assist device, is a recent introduction to the armamentarium of periprocedural hemodynamic stability tools. It has…
Triple Wire Technique for Removal of Fractured Angioplasty
Guidewire
In the performance of increasingly complex percutaneous coronary interventions (PCIs), there remains an ever-present risk of device fracture or dislodgement. Such occurrences are fortunately infrequent,1 however, they may pose an unfamiliar and diffi…
Successful Stenting of Bilateral Multiple Renal Arteries in a
Patient with Renovascular Hypertension
Renal artery stenosis (RAS) can result in renovascular hypertension and nephrosclerosis, and accounts for approximately 1 to 3% of all causes of hypertension. The current treatment of choice for atherosclerotic renal artery disease in selected patien…
Percutaneous Aortic Valvuloplasty as a Bridge to a High-Risk
Percutaneous Coronary Intervention
According to the newly-updated guidelines for the management of patients with valvular heart disease, surgical aortic valve replacement is still the gold standard for treatment of symptomatic patients with severe aortic stenosis (AS).1 However, the g…
Anterolateral Myocardial Infarction Induced by Coronary-
Subclavian-Vertebral Steal Syndrome Successfully Treated with
Stentin
Coronary-subclavian-steal syndrome (CSSS) is a known cause of myocardial infarction. This entity has been observed in individuals who present with angina. However, this case is unique because this is the first reported patient presenting not only wit…
Successful Endovascular Renal Artery Aneurysm Exclusion Using
the Venture‚Ñ¢ Catheter and Covered Stent Implantation: A Case Repo
Recent advances in balloon and stent technology have increased procedural success rates have resulted in expanded indications for percutaneous treatment of complex peripheral arterial disease. As a consequence, lesions traditionally approached with a…
