The CNN-based Coronary Occlusion Site Localization with Effective Preprocessing Method [PDF]

, 2019
The Coronary Artery Occlusion (CAO) acutely comes to human, and it highly threats the human's life. When CAO detected, Percutaneous Coronary Intervention (PCI) should be conducted timely. Before PCI, localizing the CAO is needed firstly, because the heart is covered with various arteries.

A Novel Sample-efficient Deep Reinforcement Learning with Episodic Policy Transfer for PID-Based Control in Cardiac Catheterization Robots [PDF]

arXiv, 2021
Robotic catheterization is typically used for percutaneous coronary intervention procedures nowadays and it involves steering flexible endovascular tools to open up occlusion in the coronaries. In this study, a sample-efficient deep reinforcement learning with episodic policy transfer is, for the first time, used for motion control during robotic ...

INtravaScular OptIcal Frequency Domain ImaGing EvaluaTion of the Femoropopliteal Lesion With JETSTREAM Atherectomy (INSIGHT JETSTREAM)

Catheterization and Cardiovascular Interventions, Volume 105, Issue 6, Page 1287-1295, May 1, 2025.
ABSTRACT Background There have been no prior reports of detailed evaluations using intravascular imaging during Jetstream treatment. Aims This study, therefore, aimed to investigate the effects of calcification characteristics and wire bias on lumen gain in Jetstream atherectomy using optical frequency domain imaging (OFDI). Methods This study enrolled

3D Fusion between Fluoroscopy Angiograms and SPECT Myocardial Perfusion Images to Guide Percutaneous Coronary Intervention [PDF]

arXiv, 2020
Background. Percutaneous coronary intervention(PCI) in stable coronary artery disease(CAD) is commonly triggered by abnormal myocardial perfusion imaging(MPI). However, due to the possibilities of multivessel disease and variability of coronary artery perfusion distribution, opportunity exists to better align anatomic stenosis with perfusion ...

Percutaneous Transluminal Coronary Angioplasty in Women

Cardiology, 1990
Percutaneous transluminal coronary angioplasty (PTCA) for coronary artery disease is currently as successful in women as it is in men. Acute and long-term results are similar for both sexes. Differences in the size of the coronary arteries may have accounted for gender differences in earlier series.
