Abstract

To study the effect of the Hall Kaster prosthesis on left ventricular filling characteristics after mitral valve replacement, postoperative M-mode echocardiograms of the left ventricle from sixteen patients were digitized to determine the peak rate of dimension (D) increase of the left ventricle during diastole (peak dD/dt) and the rapid filling period (RFP). These were compared with fourteen normal controls, thirty patients with Starr Edwards and thirty patients with Bjork Shiley mitral prosthesis. Results suggest that the Hall Kaster mitral prosthesis is less obstructive than either the Starr Edwards or the Bjork Shiley prosthesis, and tends to approximate the normal mitral valve.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
