Label-free evaluation of myocardial infarct in surgically excised ventricular myocardium by Raman spectroscopy [PDF]

arXiv, 2018
Understanding the viability of the ischemic myocardial tissue is a critical issue in determining the appropriate surgical procedure for patients with chronic heart failure after myocardial infarction (MI). Conventional MI evaluation methods are; however, preoperatively performed and/or give an indirect information of myocardial viability such as shape,

Deep Learning for Multi-Level Detection and Localization of Myocardial Scars Based on Regional Strain Validated on Virtual Patients [PDF]

IEEE Access, Date of Publication: 08 February 2023, Electronic ISSN: 2169-3536, Volume 11, Page(s): 15788 - 15798
How well the heart is functioning can be quantified through measurements of myocardial deformation via echocardiography. Clinical assessment of cardiac function is generally focused on global indices of relative shortening, however, territorial, and segmental strain indices have shown to be abnormal in regions of myocardial disease, such as scar.

Impact of Post Percutaneous Coronary Intervention Fractional Flow Reserve on 5‐Year Clinical Outcomes (The FFR SEARCH Study)

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) can be used to evaluate procedural success and to guide stent optimization. Several studies have demonstrated that lower FFR after stent implantation is associated with increased adverse event rates up to 2 years.

Impact of Coronary Calcification on Complete Revascularization in Patients With Acute Coronary Syndrome and Multivessel Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary calcification is a well‐known marker of atherosclerotic plaque burden and a determinant of stent under expansion with unfavorable long‐term outcomes. Aims This sub study of the randomized BIOVASC trial aimed to compare immediate complete revascularization (ICR) and staged complete revascularization (SCR) in patients with ...

The Impact of Hydrostatic Pressure on Fractional Flow Reserve in Saphenous Vein Grafts

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The relationship between height differences related to graft anatomy and physiological pressure indices in coronary bypass grafts has not been studied. We sought to study the impact of hydrostatic pressure on fractional flow reserve (FFR) in saphenous vein grafts (SVGs).

Stent Fracture of Biolimus‐Eluting Stent (Biofreedom) Complicated With Micro‐Coronary Artery Aneurysm

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Coronary stent fractures (SFs) are an emerging complication of coronary stents. There are numerous risk factors for SF, which include vessel angulation, use of sirolimus‐eluting stent (SES), long stents, multiple stent layers, stent overlap, inflammation, hypersensitivity, stenting in the right coronary artery, heavy calcification, ostial ...
