1994
New angioplasty devices have been developed to surmount the limitations of standard balloon angioplasty in complex lesion subsets. Two categories of new angioplasty devices have been used: 1) those that extract, ablate, or excise atherosclerotic plaque (atherectomy/ablative devices); and 2) those that mechanically or physiologically scaffold the inner ...

Cardiology Clinics, 1997
The first section of this article reviews how intracoronary ultrasound (ICUS) has been used to identify the mechanisms of action of directional coronary atherectomy (DCA) and examines the influence of plaque composition and morphology on DCA outcomes. The process of restenosis is then described.

Coronary Atherectomy: An Alternative to Balloon Angioplasty
AORN Journal, 1991To date, physicians at our hospital have performed coronary atherectomy on 15 patients. Of these patients, four needed open heart surgery. One patient needed surgery because a vessel was dissected during the procedure, and the three other patients had unsuccessful procedures.

Rotational Coronary Atherectomy
2003Rotational atherectomy uses the principle of high-speed abrasive differential cutting to ablate atheromatous plaque. This system, developed by David Auth, was approved for coronary use in 1993. Rotational atherectomy and other newer devices were designed principally to aid in the procedural success of percutaneous coronary intervention and potentially ...

Despite advances in interventional techniques, treatment of calcified coronary lesions remains a challenge. Stent placement in severely calcified lesions can result in stent underexpansion, malapposition, procedural complications, and worse long-term outcomes than placement in noncalcified lesions.

Rotational atherectomy in anomalous coronary arteries
Catheterization and Cardiovascular Diagnosis, 1992AbstractWe describe two cases of high speed rotational atherectomy performed in patients with anomalous coronary anatomy. These procedures are performed with standard equipment requiring no modifications using a percutaneous femoral approach. We feel these cases clearly illustrate the facile application of this new technology to unusual anatomical ...

Coronary atherectomy: Overview and implications for nursing
The Journal of Cardiovascular Nursing, 1992Coronary atherectomy, a new invasive procedure for the treatment of atherosclerotic heart disease, consists of the excision and removal of atherosclerotic tissue from coronary artery walls. This article provides current information on atherectomy, including its potential advantages over percutaneous transluminal coronary angioplasty (PTCA). Indications,

Rotational coronary atherectomy of ostial stenoses
The American Journal of Cardiology, 1993Abstract Treatment of coronary ostial stenoses with conventional balloon angioplasty may be associated with reduced procedural success rates and more frequent in-hospital complications compared with balloon angioplasty of nonostial stenoses. 1 Factors contributing to this limited success relate to both technical difficulties in maintaining adequate ...

Post-atherectomy coronary artery aneurysm
The Annals of Thoracic Surgery, 1992A 52-year-old man underwent an uneventful directional atherectomy of the left anterior descending coronary artery. Four months after the procedure unstable angina developed and on angiogram an aneurysm of the left anterior descending coronary artery was noted. The patient underwent bypass of the left anterior descending coronary artery.

Directional Coronary Atherectomy
2003Recognition of the limitations of coronary artery balloon angioplasty fostered the development of nonballoon approaches to percutaneous coronary revascularization. Directional coronary atherectomy (DCA), which received US Food and Drug Administration (FDA) approval in 1990, was the first such technique to be widely applied. The basis for this technique
