The mechanism of directional coronary atherectomy [PDF]

European Heart Journal, 1993
An attempt was made to assess the mechanism of directional coronary atherectomy using different methods of analysis. Quantitative coronary angiography was used as the gold standard to assess the immediate results of atherectomy, and a comparative quantitative analysis of atherectomy and balloon angioplasty was made.

Current Status of Coronary Atherectomy [PDF]

Cardiovascular Innovations and Applications, 2018
There are several techniques for performing coronary atherosclerotic plaque modification, known as atherectomy . Historically, clinical trials show mostly equivalence between various coronary atherectomy techniques, balloon angioplasty, and percutaneous

Coronary Intravascular Lithotripsy in a Tight Circumferential Calcified Lesion in the Presence of Haematoma Extending into Left Main Coronary Artery After Rotational Atherectomy

Interventional Cardiology: Reviews, Research, Resources, 2022
Calcified disease increases procedural challenges and is associated with worse outcomes in percutaneous coronary intervention. Coronary intravascular lithotripsy is a new balloon-based modality for treating calcified disease with deep circumferential ...

Impact of Bivalirudin on Patients with Acute Coronary Syndrome Undergoing Rotational Atherectomy in Real-Life Setting: A Retrospective Cohort Study

Anatolian Journal of Cardiology, 2023
Background: No evidence exists on the impact of bivalirudin in patients with the acute coronary syndrome undergoing rotational atherectomy. This study aimed to evaluate the impact of bivalirudin on patients with acute coronary syndrome undergoing ...

Successful Retrieval of a Fractured and Detached Crown From a Coronary Orbital Atherectomy System

JACC: Case Reports, 2020
We report a rare case of crown fracture and detachment from a coronary orbital atherectomy system. During orbital atherectomy in an angulated and calcified coronary vessel, the crown was completely detached and left distal to the stenosis.

Use of the orbital atherectomy system backed up with the guide-extension catheter for a severely tortuous calcified coronary lesion

SAGE Open Medical Case Reports, 2020
A 68-year-old man was scheduled to undergo percutaneous coronary intervention for in-stent total occlusion of the severely tortuous right coronary artery. Intravascular ultrasound revealed heavy in-stent calcification.

When rotational atherectomy is not enough

Clinical Case Reports, 2021
Extreme coronary calcification may require rotational atherectomy to create a navigable intravascular lumen followed by intravascular lithotripsy to fracture areas of deep calcification to allow for successful percutaneous coronary intervention.

Directional Coronary Atherectomy [PDF]

Circulation, 1998
Directional coronary atherectomy (DCA) was originally developed as a potential replacement for balloon angioplasty. The design of the catheter used to perform DCA offered several unique advantages. First, it was capable of removing obstructive atherosclerotic lesions.
