Force Plate Monitoring of Human Hemodynamics [PDF]

arXiv, 2005
We show that the recoils of the body caused by cardiac motion and blood circulation provide a noninvasive method capable to display the motions of the heart muscle and the propagation of the pulse wave along aorta and its branches. The results are compared with the data obtained invasively during a heart catheterization.

SCAI expert consensus statement for advanced training programs in pediatric and congenital interventional cardiac catheterization

Catheterization and cardiovascular interventions, 2014
Pediatric and Congenital Interventional Cardiology is the practice of catheter‐based techniques that improve cardiac physiology and circulation through the treatment of heart disease in children and adults with congenital or acquired heart defects.

CD16: a MATLAB-based application for estimating radiation doses from x-ray guided cardiac catheterizations in children [PDF]

arXiv, 2018
CD16 is a MATLAB-based dosimetry system designed for rapid estimation of organ doses for x-ray guided cardiac catheterization procedures. CD16 is principally designed for epidemiological studies in which dose estimates are required for thousands of cohort members, often based on limited exposure information. The minimum data required for dose estimates

The Frequency of Cardiac Arrests in Patients with Congenital Heart Disease Undergoing Cardiac Catheterization

Anesthesia and Analgesia, 2014
BACKGROUND:Cardiac catheterization for patients with congenital heart disease has shifted from diagnostic to predominantly interventional procedures because of advances in catheter-based technologies.

Acute Ischemic Stroke After Percutaneous Cardiac Intervention in an Elderly Patient

International Journal of Gerontology, 2010
Because of tremendous progress in the field of interventional cardiology and maturation in operator techniques, cardiac catheterization and percutaneous cardiac intervention have steadily become safer with improved outcomes.

Improving Catheter Segmentation & Localization in 3D Cardiac Ultrasound Using Direction-Fused FCN [PDF]

arXiv, 2019
Fast and accurate catheter detection in cardiac catheterization using harmless 3D ultrasound (US) can improve the efficiency and outcome of the intervention. However, the low image quality of US requires extra training for sonographers to localize the catheter.

Optical Hemodynamic Imaging of Jugular Venous Dynamics During Altered Central Venous Pressure [PDF]

arXiv, 2020
An optical imaging system is proposed for quantitatively assessing jugular venous response to altered central venous pressure. The proposed system assesses sub-surface optical absorption changes from jugular venous waveforms with a spatial calibration procedure to normalize incident tissue illumination.

Sex, Socioeconomic Status, Access to Cardiac Catheterization, and Outcomes for Acute Coronary Syndromes in the Context of Universal Healthcare Coverage

Circulation. Cardiovascular Quality and Outcomes, 2014
Background—Sex and neighborhood socioeconomic status (nSES) may independently affect the care and outcomes of acute coronary syndrome, partly through barriers in timely access to cardiac catheterization.

Contour and Centreline Tracking of Vessels from Angiograms using the Classical Image Processing Techniques [PDF]

Buletinul Institutului Politehnic din Iasi, Sectia Automatica si Calculatoare, Vol. 62(66), No. 3, pp. 49-60, July 2016, ISSN 1220-2169, 2017
This article deals with the problem of vessel edge and centerline detection using classical image processing techniques due to their simpleness and easiness to be implemented. The method is divided into four steps: the vessel enhancement which implies a non-linear filtering proposed by Frangi, the thresholding using Otsu method and the contour ...
