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…
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…
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…
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…
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…
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…
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…
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…
Coronary angioplasty procedures involving bifurcations are still challenges with no easy solutions. Kissing wire and balloon techniques,1-2 directional and rotational atherectomy3-8 and excimer laser angioplasty9 have not resulted in satisfactory sho…
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…
