Robust Landmark-based Stent Tracking in X-ray Fluoroscopy [PDF]
arXiv, 2022 In clinical procedures of angioplasty (i.e., open clogged coronary arteries), devices such as balloons and stents need to be placed and expanded in arteries under the guidance of X-ray fluoroscopy. Due to the limitation of X-ray dose, the resulting images are often noisy.

Giant Right Coronary Artery Aneurysm Following Percutaneous Transluminal Coronary Angioplasty
Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2021 Coronary artery aneurysm following percutaneous coronary angioplasty (PTCA) is rare in interventional cardiology. Several factors may contribute to the development of such complication following PTCA that include stent size, improper apposition, nature ...

Dynamic Coronary Roadmapping via Catheter Tip Tracking in X-ray Fluoroscopy with Deep Learning Based Bayesian Filtering [PDF]
, 2020 Percutaneous coronary intervention (PCI) is typically performed with image guidance using X-ray angiograms in which coronary arteries are opacified with X-ray opaque contrast agents. Interventional cardiologists typically navigate instruments using non-contrast-enhanced fluoroscopic images, since higher use of contrast agents increases the risk of ...

Measurement of Individual Alteration in Perioperative ECGs During Elective Percutaneous Coronary Intervention [PDF]
arXiv, 2023 The increasing availability of wearable electrocardiography (ECG) devices enables the continuous monitoring of individual ECG alterations. This could be beneficial for patients suffering from acute ischemia but with non-standard ECG findings that do not fit to the subject-independent and absolute thresholds defined in clinical guidelines. In this work,

The Road to the Ideal Stent: A Review of Stent Design Optimisation Methods, Findings, and Opportunities [PDF]
, 2023 Coronary stent designs have undergone significant transformations in geometry, materials, and drug elution coatings, contributing to the continuous improvement of stenting success over recent decades. However, the increasing use of percutaneous coronary intervention techniques on complex coronary artery disease anatomy continues to be a challenge and ...

Rounded notch method of femoral endarterectomy offers mechanical advantages in finite element models [PDF]
arXiv, 2023 Objective: Use of a vascular punch to produce circular heel and toe arteriotomies for femoral endarterectomy with patch angioplasty is a novel technique. This study investigated the plausibility of this approach and the mechanical advantages of the technique using finite element models.
