Left Ventricular Size, Mass, and Shape

Determination of left ventricular size and shape.

• The importance of ventricular size and shape in determining cardiac function has been recognized for over 80 years; the concept is embodied in the Frank-Starling mechanism and in Laplace's law of the heart. However, over this same period, chamber pressure and cardiac output rather than ventricular dimensions have been measured to assess cardiac function, largely because cardiac catheterizatio...

Relation between coronary artery size and left ventricular wall mass.

The cross-sectional area of the lumen of the proximal right coronary artery and the main stem of the left coronary artery were measured in 27 patients-6 normal subjects, 8 with minor coronary artery disease, 8 with aortic incompetence, 3 with primary myocardial disease, and 2 with a prolapsing posterior leaflet of the mitral valve and mild mitral incompetence. There was close linear correlation...

echocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction

background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy   (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction   is associated with lvh and inappropriate lvm. methods: one hundred   and twenty five uncomplicated hypertensi...

Effects of Surgical Ventricular Restoration on Left Ventricular Shape, Size, and Function for Left Ventricular Anterior Aneurysm

BACKGROUND Surgical ventricular restoration (SVR) has been performed to treat left ventricular (LV) aneurysm. However, there is limited analysis of changes in LV shape. This study aimed to evaluate the changes in LV shape induced by SVR and the effects of SVR on LV size and function for LV aneurysm. METHODS Between April 2006 and March 2015, 18 patients with dyskinetic (dyskinetic group) and ...
