Journal ArticleDOI
Weighted least-squares finite elements based on particle imaging velocimetry data
Jeffrey J. Heys,Thomas A. Manteuffel,Stephen F. McCormick,Michele Milano,John Westerdale,Marek Belohlavek +5 more
TL;DR: The potential of least-squares finite element methods (LSFEM) is examined and by weighting the boundary conditions in a manner that properly reflects the accuracy with which the boundary values are known, the weighted LSFEM is developed.
Journal ArticleDOI
Selective echocardiographic analysis of epicardial and endocardial left ventricular rotational mechanics in an animal model of pericardial adhesions
Mohsen S. Alharthi,Panupong Jiamsripong,Anna M. Calleja,Partho P. Sengupta,Eileen M. McMahon,Bijoy K. Khandheria,A. Jamil Tajik,Marek Belohlavek +7 more
TL;DR: The model suggests that early-stage pericardial adhesions reduce both epicardial and endocardial LV twist and torsion without a significant alteration in their transmural gradient.
Journal ArticleDOI
Electromechanical Activation Sequence in Normal Heart
TL;DR: The transmural shortening and lengthening sequences are linked with the myofiber architecture of the left ventricular wall to explain the global three-dimensional twisting deformation of the LV.
Journal ArticleDOI
Arterioventricular Coupling and Ventricular Efficiency After Antihypertensive Therapy. A Noninvasive Prospective Study
Martin Osranek,John H. Eisenach,Bijoy K. Khandheria,Krishnaswamy Chandrasekaran,James B. Seward,Marek Belohlavek +5 more
TL;DR: In hypertensive patients, optimal brachial and central blood pressure reduction shifts arterioventricular coupling from cardiac output maximization to ventricular mechanical efficiency optimization, which occurs before significant changes in ventricular geometry and may be responsible for early clinical improvements.
Journal ArticleDOI
Intracardiac measurement of pre-ejection myocardial velocities estimates the transmural extent of viable myocardium early after reperfusion in acute myocardial infarction
TL;DR: Pre-ejection tissue velocity, as measured by intracardiac ultrasound, allows rapid estimation of the transmural extent of viable myocardium after reperfusion for acute myocardial infarction (AMI).
