Numerical analysis of the impact of flow rate, heart rate, vessel geometry, and degree of stenosis on coronary hemodynamic indices

BMC Cardiovascular Disorders, 2018
Background The stenosis of the coronary arteries is usually caused by atherosclerosis. Hemodynamic significance of patient-specific coronary stenoses and the risk of its progression may be assessed by comparing the hemodynamic effects induced by flow ...

Rationale and design of the Clinical Evaluation of Magnetic Resonance Imaging in Coronary heart disease 2 trial (CE-MARC 2): a prospective, multicenter, randomized trial of diagnostic strategies in suspected coronary heart disease [PDF]

, 2015
Background: A number of investigative strategies exist for the diagnosis of coronary heart disease (CHD). Despite the widespread availability of noninvasive imaging, invasive angiography is commonly used early in the diagnostic pathway.

Commissural Misalignment Following Valve‐in‐Valve Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Data on commissural misalignment (CMA) during valve‐in‐valve transcatheter aortic valve implantation (ViV‐TAVI) for valve failure after surgical aortic valve replacement (SAVR) is scarce. Aims To study the impact of CMA on clinical and hemodynamic outcomes following ViV‐TAVI for failed SAVR.

Isolated Coronary Ostial Stenosis Associated With Coronary Vasopasm

Japanese Circulation Journal, 2000
A 50-year-old woman was brought to the emergency room in a preshock condition. An emergency coronary angiogram revealed 90% ostial stenosis of the left coronary artery with delayed distal filling. After intracoronary nitrate, the degree of stenosis was reduced to 75%; no other coronary lesions were evident. The patient was found to have hyperthyroidism

Extremity Function After Transfemoral Transcatheter Aortic Valve Implantation: A TAVI XS Sub‐Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Physical decline after transcatheter aortic valve implantation (TAVI) is associated with worse outcomes. However, data on post‐TAVI extremity function are limited. This sub‐study of the TAVI XS trial aimed to assess extremity function after transfemoral TAVI, evaluate functional decline, compare outcomes between upper‐and lower ...

Left Ventricular Outflow Tract Geometry as a Predictor of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation Using the Evolut Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Predicting the need for permanent pacemaker implantation (PPM) after transcatheter aortic valve implantation (TAVI) is crucial for procedural planning and patient counseling. Aims To evaluate whether left ventricular outflow tract (LVOT) morphology, specifically a tapered configuration, predicts conduction disturbances requiring PPM

Robust semi-automated path extraction for visualising stenosis of the coronary arteries [PDF]

, 2008
Computed tomography angiography (CTA) is useful for diagnosing and planning treatment of heart disease. However, contrast agent in surrounding structures (such as the aorta and left ventricle) makes 3-D visualisation of the coronary arteries difficult ...
