Comparison of cardiac DTI parameters between systole and diastole

Journal of Cardiovascular Magnetic Resonance, 2014
Results Two of the original 46 volunteers were excluded due to ECG irregularities. Data from one further volunteer was incomplete and therefore excluded from the final analysis. Results from the remaining 43 volunteers are in table 1.

Generic systolic arrays: A methodology for systolic design [PDF]

, 1993
Several recent papers demonstrate the interest of viewing systolic algorithms as while-programs whose statements are synchronous multiple assignments. This approach is based on the classical invariant method and compares favourably with earlier ones, based on recurrence systems and space-time transformations.

Systolic tree acceptors [PDF]

RAIRO. Informatique théorique, 1984
Motivated by VLSI and systolic arrays this paper introduces a new kind of automata as language acceptors: systolic tree acceptors (STA). Like in a tree representing an arithmetical expression an operator or function symbol is associated with each (internal) node of the tree.

Long‐Term Survival After Post‐Myocardial Infarction Ventricular Septal Defect (VSD) Closure, Multiple Percutaneous Coronary Interventions and Edge‐to‐Edge Repair

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT This reports a case of a female aged 65 who presented in cardiogenic shock secondary to an inferior ST‐elevation myocardial infarction and was diagnosed with a post‐infarction ventricular septal defect (VSD) and was also found to have severe mitral valve regurgitation. She was not surgically operable, so underwent percutaneous VSD repair. Over

Transfemoral Transcatheter Aortic Valve Implantation (TF‐TAVI) for Patients With Left Ventricular Assist Device (LVAD) and Aortic Regurgitation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aortic regurgitation (AR) develops in up to 25%−30% of patients with left ventricular assist device (LVAD). Treatment remains challenging since surgery confers significant peri‐operative risk and the lack of valvular calcification renders transfemoral transcatheter aortic valve implantation (TF‐TAVI) with non‐dedicated devices technically ...

Small eigenvalues of surfaces - old and new

, 2017
We discuss our recent work on small eigenvalues of surfaces. As an introduction, we present and extend some of the by now classical work of Buser and Randol and explain novel ideas from articles of S\'evennec, Otal, and Otal-Rosas which are of importance

Study of ventricular electrical systole in patients with end-stage kidney disease on hemodialysis.

Arquivos Brasileiros de Cardiologia, 2013
BACKGROUND Patients with end-stage kidney disease (ESKD) experience elevated cardiac stress because of the repetitive and intermittent character of dialysis. Changes in ventricular electrical systole induced by necessary dialysis significantly contribute

Left Ventricular Apical Thrombus in Apical Hypertrophic Cardiomyopathy Without Aneurysm or Arrhythmia: A Case Report

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Apical hypertrophic cardiomyopathy (ApHCM) is a rare variant of hypertrophic cardiomyopathy, typically associated with a benign course. However, complications such as ventricular arrhythmias, apical aneurysms, and thrombus formation may occur. Left ventricular (LV) thrombus is an unusual finding in ApHCM, especially in patients with preserved ...

Diastolic-systolic velocity ratio to detect coronary stenoses under physiological resting conditions: a mechanistic study

Open Heart, 2019
Objective Diastolic-systolic velocity ratio (DSVR) is a resting index to assess stenoses in the left anterior descending artery (LAD). DSVR can be measured by echocardiographic or intracoronary Doppler flow velocity.

A coupled mitral valve -- left ventricle model with fluid-structure interaction

, 2017
Understanding the interaction between the valves and walls of the heart is important in assessing and subsequently treating heart dysfunction. With advancements in cardiac imaging, nonlinear mechanics and computational techniques, it is now possible to ...
