The basic heart anatomy and physiology from the cardiologist's perspective: Toward a better understanding of left ventricular mechanics, systolic, and diastolic function

Abstract

A comprehensive understanding of the cardiac structure–function relationship is essential for proper clinical cardiac imaging. This review summarizes the basic heart anatomy and physiology from the perspective of a heart imager focused on myocardial mechanics. The main issues analyzed are the left ventricular (LV) architecture, the LV myocardial deformation through the cardiac cycle, the LV diastolic function basic parameters and the basic parameters of the LV deformation used in clinical practice for the LV function assessment.

Ultraschall in der Intensivmedizin: Abdomen- und Lungensonografie sowie Echokardiografie

“…Die Rate an falsch negativen Befunden beträgt im Fall von extraintestinaler Luft zwischen 10 % und 30 % [15,16]. Die grundlegenden transthorakalen Schnittebenen werden nur kurz wie folgt skizziert [17,18,19,20,21].…”

Left ventricle function and post-transcriptional events with exercise training in pigs

“…diastolic function) as well as LV ejection performance have improved with exercise training. LV diastolic function is highly dependent upon LV chamber stiffness [5,6], however, the direct effects of an exercise training protocol on LV stiffness properties are not well understood and may be due in part to confounding factors in clinical studies such as comorbidities, differences in the exercise protocols, and the complexity of measurements. Pigs have been successfully utilized for exercise training studies with respect to cardiovascular function [7,8].…”
