Multi Modality Imaging for Cardiac Masses Can Avoid Unnecessary Surgical Intervention: A Case Report of Caseous Calcification of Mitral Annulus
Caseous Calcification of Mitral Annulus Cardiac Tumors Cardiac MR
2013/1/29
Mitral Annular Calcification (MAC) is a degenerative process involving the fibrous ring of the mitral valve. Caseous Calcification of Mitral Annulus (CCMA) is a rare variant of MAC. This condition is ...
Gestation-specific reference intervals for fetal cardiac Doppler indices from 12 to 40 weeks of gestation
Cardiac Doppler Fetal Gestation Age Reference Range Ultrasound
2013/1/31
We aimed to establish gestation age specific reference intervals for Doppler indices of fetal cardiac function from 12 to 40 weeks of pregnancy. In a cross-sectional observational study of singleton p...
Multi-center pragmatic studies evaluating the time indicator of cardiac perfusion reserve
Ratio of Diastolic to Systolic Duration (D/S) Accuracy Precision Cardiac Reserve Cardiac Safety Fitness
2013/1/28
Background: Since the greater part of coronary blood flow takes place during the diastolic phase of each cardiac cycle, a time indicator of myocardial perfusion reserve, the ratio of diastolic to syst...
Adult Cardiac-Related Deaths: A Reflection of Epidemiologic Transition of Diseases in the Developing World?
Cardiac Deaths Disease Transition
2013/2/20
Background: Epidemiologic transition of diseases is taking place globally. Therefore, it is necessary that more work is done to unravel the situation in respect to cardiac diseases in the developing w...

Rock1 Inhibitor Abrogates Chronic Rejection in Rat Cardiac Model System
Chronic Rejection Transplantation ROCK1 RhoA T Cell
2013/1/31
Background: We have shown previously that the abrogation of acute and chronic rejection of rat cardiac allografts occurs through the down-regulation of RhoA pathway and involves the changes in RhoA ki...
