High-Resolution, Three-Dimensional Reconstruction of the Outflow Tract Demonstrates Segmental Differences in Cleared Eyes [PDF]

arXiv, 2017
Purpose: The rate of conventional aqueous humor outflow is the highest nasally. We hypothesized that this is reflected in regionally different outflow structures and analyzed the entire limbus by high-resolution, full-thickness ribbon-scanning confocal microscopy (RSCM).

Combined tract segmentation and orientation mapping for bundle-specific tractography [PDF]

, 2019
While the major white matter tracts are of great interest to numerous studies in neuroscience and medicine, their manual dissection in larger cohorts from diffusion MRI tractograms is time-consuming, requires expert knowledge and is hard to reproduce. In previous work we presented tract orientation mapping (TOM) as a novel concept for bundle-specific ...

Hybrid Transcatheter Pulmonary Valve Replacement With SAPIEN S3 Following Right Ventricular Outflow Tract Reduction Using Tricuspid Annuloplasty Rings

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We describe a novel variation of hybrid TPVR using a tricuspid annuloplasty ring which can be considered for patients with very large RVOT, short pulmonary artery, and limited vascular access and to avoid the risk of cardiopulmonary bypass. The utilization of Carpentier‐Edwards Physio Tricuspid annuloplasty ring can reduce the size of the RVOT

The Australia and New Zealand Congenital Outcomes Registry for Surgery (ANZCORS): methodology and preliminary results

ANZ Journal of Surgery, Volume 92, Issue 12, Page 3154-3161, December 2022., 2022
Analysis of multi‐institutional data and benchmarking is an accepted accreditation standard in cardiac surgery. Such a database does not exist for congenital cardiac surgery in Australia and New Zealand (ANZ). To fill this gap, the ANZ Congenital Outcomes Registry for Surgery (ANZCORS) was established in 2017.

Shortening of the Short Refractory Periods in Short QT Syndrome

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundDiagnosis of short QT syndrome (SQTS) remains difficult in case of borderline QT values as often found in normal populations. Whether some shortening of refractory periods (RP) may help in differentiating SQTS from normal subjects is unknown ...

A Novel Mathematical/Numerical Formula for Assessing Right Ventricular Torsion Using Echocardiographic Imaging [PDF]

arXiv, 2015
Recently, the ventricular torsional parameters have received special attention because of their significant role in the ventricular systolic and diastolic function. Right ventricular (RV) rotational deformation is a sensitive index for RV performance but difficult to measure.

Ventricular torsional relation to ventricular fiber arrangement [PDF]

arXiv, 2014
Left ventricular torsion from helically oriented myofibers is a key parameter of cardiac performance. Physicians observing heart motion on echocardiograms, during cardiac catheterization, or in the operating room, are impressed by the twisting or rotary motion of the left ventricle during systole.

Metabolic changes during cardiac regeneration in the axolotl

Developmental Dynamics, EarlyView.
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Characterization of left atrial assist device implantation: Early results of ex vivo anatomical assessment

Artificial Organs, Volume 47, Issue 1, Page 129-137, January 2023., 2023
Device‐based therapies for heart failure with preserved ejection fraction are limited, but the left atrial assist device pump is making progress as one option. Since the implantation site is unique, options for device orientation, driveline exteriorization, and exit sites must be demonstrated.

Identifying logarithmic tracts [PDF]

arXiv, 2019
We show that a direct tract bounded by a simple curve is a logarithmic tract and further give sufficient conditions for a direct tract to contain logarithmic tracts. As an application of these results, an example of a function with infinitely many direct singularities, but no logarithmic singularity over any finite value, is shown to be in the Eremenko-
