Unprotected Left Main Coronary Artery Bifurcation Stenosis
Impact of Plaque Debulking Prior to Single Sirolimus-Eluting Stent ImplantationABSTRACT: Background. The impact of plaque debulking with directional coronary atherectomy (DCA) prior to single sirolimus-eluting stent (SES) implantation in an unprotect…
Stenting in Unusual Settings: Compression of a Subintimal or False Lumen Stent by Stenting in the True Lumen
Since stents were first approved in the United States for clinical use in the fourth quarter of 1993, their use has skyrocketed with 890,000 stents implanted in coronary arteries in 550,000 interventions in the United States in 1999.1 A variety of co…
Stenting in Unusual Settings:
Rotational Atherectomy of a Stent-Jailed Septal Perforator: A Good Verdict for the Prisoner
Catheter-based techniques for revascularization offer a good solution to the vexing problem of stenosis in septal perforators, which are not accessible to surgical grafting, and which often are erroneously relegated as inconsequential. Stenosis of la…
False Aneurysm and Mediastinal Hematoma: Complications of Simultaneous Transcatheter Therapy for Coarctation of the Aorta and Pa
Coarctation of the aorta (CoA) is frequently associated with patent ductus arteriosus (PDA). Balloon angioplasty of CoA and coil treatment of PDA has been reported as an effective alternative to surgical therapy. However, simultaneous interventional…
Congenital Coarctation and Takayasu’s Arteritis: Aortic Stenting Employing Intravascular
Ultrasound
Case Report. A 23-year-old woman was admitted for evaluation and treatment of aortic coarctation. She was first noted to have a murmur in infancy but did well throughout her early childhood years and no intervention was recommended. She remained free…
Stenting in Unusual Settings:
Stenting of the Septal Perforator Coronary Artery
The interventricular septum (IVS), which is a common wall for the right and left ventricles, makes up about one-third of the total left ventricular mass and plays an important role in both right and left ventricular function.1 The major part of the I…
In-Hospital and Long-Term Outcomes of Patients with Acute Myocardial Infarction Undergoing Direct Angioplasty During Regular and
Direct percutaneous coronary angioplasty (d-PTCA) has emerged as an effective reperfusion strategy in patients presenting within the first 12 hours of an acute myocardial infarction as compared to intravenous thrombolytics.1–5 Several randomized thro…
Coronary Angiography Using 4 or 6 French Diagnostic Catheters: A Prospective, Randomized Study
Since its introduction by M. Sones in 1962,1 the technique of coronary catheterization has been evolving, allowing for progressive improvements in catheter quality in terms of design as well as external and internal diameter. The progressive reductio…
Pre-Operative Intra-Aortic Balloon
Counterpulsation in Stable Patients with
Left Main Coronary Disease
The use of intra-aortic balloon counterpulsation (IABC) to reduce left ventricular afterload and myocardial oxygen consumption is clearly indicated in patients with refractory myocardial ischemia or acute myocardial infarction complicated by cardioge…
Predictors of Mortality at 30 Days in High-Risk Patients Treated with Direct or Rescue Stenting
for Acute Myocardial Infarction
Large-scale trials reported the benefits of coronary angioplasty over systemic thrombolysis for the treatment of acute myocardial infarction (AMI).1,2 More recent studies demonstrated that stenting can determine a further improvement in results over…
