Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

The architecture of the left ventricular myocytes relative to left ventricular systolic function [PDF]

, 2017
Objective: Mural thickening, combined with longitudinal and circumferential shortening, and apical along with basal twisting are critical components of the left ventricular systolic deformation that contribute to ventricular ejection.

Three-dimensional structure of the flow inside the left ventricle of the human heart [PDF]

Exp Fluids (2013) 54(1):1-9, 2014
The laboratory models of the human heart left ventricle developed in the last decades gave a valuable contribution to the comprehension of the role of the fluid dynamics in the cardiac function and to support the interpretation of the data obtained in vivo.

Impact of Diabetes on Long‐Term Outcomes of Percutaneous Coronary Intervention for Coronary Bifurcation Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Diabetes mellitus (DM) is a well‐known risk factor for cardiovascular diseases, including coronary artery diseases (CAD). Complex percutaneous coronary intervention (PCI) such as PCI for bifurcation lesions often yields poor outcomes, especially in DM patients.

Left Ventricular Unloading in Nonischemic Dilated Cardiomyopathy Improves Coronary Haemodynamic Reserve

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The Impella CP is a catheter‐based ventricular assist device used in the management of cardiogenic shock and to support high‐risk percutaneous coronary interventions (PCI). Despite its growing use, the effects of Impella CP on coronary flow dynamics as measured by intracoronary continuous thermodilution have not been fully ...

Elucidating the cellular determinants of the end-systolic pressure-volume relationship of the heart via computational modelling [PDF]

arXiv
The left ventricular end-systolic pressure-volume relationship (ESPVr) is a key indicator of cardiac contractility. Despite its established importance, several studies suggested that the mechanical mode of contraction, such as isovolumetric or ejecting contractions, may affect the ESPVr, challenging the traditional notion of a single, consistent ...

Assimilated LVEF: A Bayesian technique combining human intuition with machine measurement for sharper estimates of left ventricular ejection fraction and stronger association with outcomes [PDF]

arXiv, 2018
The cardiologist's main tool for measuring systolic heart failure is left ventricular ejection fraction (LVEF). Trained cardiologist's report both a visual and machine-guided measurement of LVEF, but only use this machine-guided measurement in analysis.

Impact of Elevated Preprocedural Left Ventricular Filling Pressure on Prognosis of Mild Paravalvular Regurgitation Following Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Paravalvular regurgitation (PVR) following transcatheter aortic valve replacement (TAVR) is a complication linked to poor outcomes. The prognostic impact of mild PVR, particularly in patients with elevated preprocedural left ventricular (LV) filling pressure, remains uncertain.

Restoration of a Stuck Leaflet

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Severe aortic regurgitation (AR) for a leaflet malfunction after transcatheter aortic valve implantation (TAVI) is a dreadful complication that can lead even to cardiogenic shock. New valve's design has reduced the rate of paravalvular regurgitation, however central regurgitation is still a challenging complication.
