Diastolic left ventricular functional indices: Comparison between gated myocardial perfusion SPECT and echocardiography
Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...
متن کاملNormal values of left ventricular functional indices in gated 99mTc-MIBI myocardial perfusion SPECT
Introduction: Although left ventricular(LV) function parameters measured by gated myocardial perfusion SPECT (GSPECT) have been validated, experimental data have revealed that the calculated the LV function parameters using GSPECT are affected by patient populations as well as particular acquisition and processing conditions. We tried to determine the normal values ...
متن کاملImplantable left ventricular assist system.
The first clinical application of the first-generation pulsatile implantable left ventricular assist system (LVAS) was in the mid 1980 s as a bridge to transplantation and contributed to an advancement of this field from a clinical experiment to an established therapeutic option for treating advanced heart failure patients. However, there have been technological limitations that have surfaced a...
متن کاملMorphological image analysis of left - ventricular endocardial
Assessment of cardiac function using imaging techniques requires accurate identiication of borders. We have developed a semi-automatic method for boundary detection of echocardiographic images. Our method combines morphological image analysis techniques with a second derivative operator, namely Laplican of Gaussian. Morphological ltering is used to reduce noise and increase contrast of the imag...
متن کاملNovel Left Ventricular Assist System
We propose a Novel Left Ventricular Assist System (Novel LVAS) as a bridge to cardiac transplantation and to functional heart recovery in advanced heart failure. This report regards the principles that led to its development. It is our hope that the design of a high-peak-output pump of smaller size will lead to improved functional capacity, when compared with currently available left ventricula...
