  • Hypertension
  • Left ventricular hypertrophy (LVH) can have many origins, which may include hypertension, aortic stenosis, and congenital or genetic defects. (ahajournals.org)
  • 1 2 Because hypertension and aortic stenosis place different mechanical loads on the heart, present the heart with different neuroendocrine environments, and result in chronically different coronary artery perfusion pressures, it seems likely that differences exist in the biochemistry of myocardium remodeled by hypertension and aortic stenosis.

  • echocardiographic
  • The peak left ventricular pressure ranged from 150 ± 5 to 386 ± 22 mm Hg (mean ± Sl), was reproducible in each patient with each balloon inflation (mean coefficient of variation 7.8%) and correlated with concurrent echocardiographic measurements of ejection fraction (r = 0.89, p = 0.0001) and mass/volume ratio in systole (r = 0.91, p = 0.0001) or diastole (r = 0.88, p = 0.0001).

  • Doppler
  • Of 62 patients with clinical signs of elevated right-sided pressures, 54 (87%) had jets of tricuspid regurgitation clearly recorded by continuous-wave Doppler ultrasound. (ahajournals.org)
  • I have tried a fusion Image of doppler mitral Inflow in diastole and Aortic pressure curve during ssytole to bring PV loop an anatomical perspective. (drsvenkatesan.com)
  • pleural
  • By combining conventional methods for recording pressures from the left ventricle and pleural cavity with a new procedure for estimating end-diastolic volume (EDV) and end-systolic volume (ESV) of the left ventricle it was found in the closed-chest dog that plethora increased EDV, ESV and stroke volume while hemorrhage had the opposite effect.

  • waveforms
  • However, pressure decay does not necessarily follow any of these waveforms (14) , and systematic discrepancies between real and assumed pressure decay for healthy versus diseased hearts could potentially affect quantitative disparities in relaxation load dependence or drug sensitivity.

  • abnormal
  • These results suggest that an index of eccentric left ventricular shape which reflects abnormal motion of the interventricular septum can be defined. (nih.gov)
  • METHODS
  • METHODS: In 7 anaesthetised adult pigs, we measured LVPVR using conductance volumetry and tip manometry along with measurement of pericardial and other intrathoracic pressures. (diva-portal.org)
  • We contrasted various methods for assessing ventricular pressure decay time constants to test whether sensitivity to slight data instability or disparities between model-assumed and real decay are systematically altered by cardiac failure. (onlinejacc.org)
  • mitral
  • A ratio of early transmitral flow velocity (E) to early diastolic mitral annular velocity (E′) and a time interval between onsets of E and E′ (T E′-E ) has been proposed as a novel index to assess left ventricular (LV) filling pressure (FP). (ahajournals.org)
