A multiscale model of vascular function in chronic thromboembolic pulmonary hypertension [PDF]

, 2021
Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by recurrent or unresolved pulmonary thromboemboli, leading to perfusion defects and increased arterial wave reflections. CTEPH treatment aims to reduce pulmonary arterial pressure and reestablish adequate lung perfusion, yet patients with distal lesions are inoperable by standard surgical

A method of characterising the complex anatomy of vascular occlusions and 3D printing biomimetic analogues

Journal of Anatomy, Volume 242, Issue 1, Page 64-75, January 2023., 2023
We have described a microcomputed tomography method which provides multi‐material detail on the calcified and soft tissue components of vascular occlusions. This is enables models of various components of the occlusion to be 3D printed, for use in the creation of biomimetic analogues.

A comparison of balloon-expandable-stent implantation with balloon angioplasty in patients with coronary artery disease. Benestent Study Group.

New England Journal of Medicine, 1994
BACKGROUND Balloon-expandable coronary-artery stents were developed to prevent coronary restenosis after coronary angioplasty. These devices hold coronary vessels open at sites that have been dilated. However, it is unknown whether stenting improves long-

Anatomical variation of the aorta in the West of Scotland – A population with high cardiovascular disease burden. Implications for stent design and deployment

Journal of Anatomy, Volume 242, Issue 1, Page 112-120, January 2023., 2023
A population with a high cardiovascular disease burden was found to have a high degree of anatomical variation in the aortic arch (angulation from coronal plane, origin of the vertebral artery) and the abdominal aorta regions (high degree of taper, high number of collaterals and tortuous vessels).

Comparison of Primary Patency Rate between Drug- Coated Balloon and Plain Balloon Angioplasty in Hemodialysis Access

Siriraj Medical Journal, 2022
Objective: Hemodialysis adequacy in end-stage renal disease patients plays a crucial role in their quality of life. Repeated stenosis at the anastomotic site of arteriovenous fistula and synthetic arteriovenous graft are a major cause of access failure ...

A thermodynamic framework for unified continuum models for the healing of damaged soft biological tissue [PDF]

, 2021
When they are damaged or injured, soft biological tissues are able to self-repair and heal. Mechanics is critical during the healing process, as the damaged extracellular matrix (ECM) tends to be replaced with a new undamaged ECM supporting homeostatic stresses. Computational modeling has been commonly used to simulate the healing process.

Peripheral pulmonary stenosis with Noonan syndrome treated by balloon pulmonary angioplasty

Pulmonary Circulation, 2020
Noonan syndrome is known to have various cardiovascular defects, which include pulmonary artery stenosis. Pulmonary artery stenosis is characterized by obstruction of pulmonary artery blood flow that can cause elevated pulmonary artery pressure and ...

Drug Coated Balloon Angioplasty in Failing AV Fistulas: A Randomized Controlled Trial.

American Society of Nephrology. Clinical Journal, 2018
BACKGROUND Restenosis remains a problem in hemodialysis access interventions. Paclitaxel-coated balloons have shown promise in reducing access-related restenosis in small trials.
