The Effect of “Unclassified” Blood Pressure Phenotypes on Left Ventricular Hypertrophy

Turkish Archives of Pediatrics
Objective: We aimed to evaluate the clinical significance of the “unclassified” blood pressure phenotypes on left ventricular hypertrophy in children.

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.

Evaluation of factors associated with selection for coronary angiography and in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest without ST‐segment elevation

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1159-1170, December 1, 2022., 2022
Abstract Background Clinical factors favouring coronary angiography (CA) selection and variables associated with in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest (OHCA) without ST‐segment elevation (STE) remain unclear.

Computer simulation of surgical interventions for the treatment of refractory pulmonary hypertension [PDF]

arXiv, 2021
This paper describes computer models of three interventions used for treating refractory pulmonary hypertension (RPH). These procedures create either an atrial septal defect, a ventricular septal defect, or, in the case of a Potts shunt, a patent ductus arteriosus.

Right Atrial and Ventricular Adaptation to Chronic Right Ventricular Pressure Overload [PDF]

Circulation, 2005
Background— Increased mortality in patients with chronic pulmonary hypertension has been associated with elevated right atrial (RA) pressure. However, little is known about the effects of chronic right ventricular (RV) pressure overload on RA and RV dynamics or the adaptive response of the right ...

Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...

Cognitive function in late‐stage HFpEF patients with tricuspid regurgitation undergoing transcatheter tricuspid valve intervention

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1323-1330, December 1, 2022., 2022
Abstract Objectives This study evaluates the impact of transcatheter tricuspid valve interventions (TTVI) on cognitive function (CF), quality of life (QOL), and exercise capacity in late‐stage heart failure with preserved ejection fraction (HFpEF) and relevant tricuspid regurgitation (TR).

Electromechanical modeling of human ventricles with ischemic cardiomyopathy: numerical simulations in sinus rhythm and under arrhythmia [PDF]

arXiv, 2021
We developed a novel patient-specific computational model for the numerical simulation of ventricular electromechanics in patients with ischemic cardiomyopathy (ICM). This model reproduces the activity both in sinus rhythm (SR) and in ventricular tachycardia (VT).

Left ventricular end‐diastolic pressure in evaluating left ventricular function [PDF]

Clinical Cardiology, 1981
AbstractThere are several factors that could affect the left ventricular end‐diastolic pressure. These include heart rate, preload, afterload, pericardial or pleural pressure, diastolic properties of the left ventricle, and the left ventricular inotropic state.
