In vitro and animal experiments have shown that the severity of coronary stenoses can be assessed using the continuity equation if the maximal blood flow velocity of the stenotic jet is measured. The large diameter and the low range of velocities measurable without frequency aliasing with the conventional intracoronary Doppler catheters precluded the clinical application of this method for hemodynamically significant coronary stenoses in humans. This article reports the results obtained using a… Expand
Hemodynamic significance of coronary jet velocity in patients: limitations of the Bernouilli equation in small conduits.
TLDR
The objective of this study was to assess the use of coronary stenosis velocity in the determination of translesional pressure gradients and to compare the instantaneous velocity calculations of pressure by the simplified Bernouilli formula with both maximal jet velocity and a modified formula including proximal velocity. Expand
Use of the continuity equation for transesophageal Doppler assessment of severity of proximal left coronary artery stenosis: a quantitative coronary angiography validation study.
TLDR
TEDE may be used for quantitating stenosis of the proximal part of the LCA with the use of a modified continuity equation that takes into account the parabolic velocity profile in the normal prestenotic segment. Expand
Assessment of coronary stenoses by Doppler wires: a validation study using in vitro modeling and computer simulations.
TLDR
Doppler guidewire measurements of intracoronary flow velocities are useful to assess the severity of coronary stenoses, however, in vitro results and computer simulations indicate that guidewires alter the flow profile, so that Doppler velocity reserve may underestimate the true flow reserve. Expand
Resting coronary flow velocity in the functional evaluation of coronary artery stenosis: study on sequential use of computed tomography angiography and transthoracic Doppler echocardiography.
TLDR
Sequential use of CTA and TTDE is feasible for combined anatomic and functional evaluation of coronary stenoses and compared with coronary CTA alone, addition of TTDE improved PPV for detection of significant CAD. Expand
Assessment of coronary artery stenosis with intracoronary Doppler guide wire and modified continuity equation method ; A comparison with dipyridamole stress Thallium-201 SPECT
TLDR
Application of intracoronary Doppler guide wire and modified continuity equation method appears to provide useful on-site implications for the anatomic and functional assessment of coronary artery stenosis. Expand
Fractional flow reserve. A useful index to evaluate the influence of an epicardial coronary stenosis on myocardial blood flow.
TLDR
A value of FFRmyo of 0.74 reliably discriminates coronary stenosis, whether associated with inducible ischemia or not, and is a useful index to determine the functional significance of an epicardial coronary stenoses and may facilitate clinical decision making in patients with an equivocal coronary stenotic.

Improved high-frequency transthoracic flow velocity measurement in the left anterior descending coronary artery after intravenous peripheral injection of levovist.
TLDR
High-frequency TTDM provides reliable data on APV in the majority of patients and has the potential to be introduced as a relevant screening test for follow-up of patients after interventional treatment. Expand
Detection, location, and severity assessment of left anterior descending coronary artery stenoses by means of contrast-enhanced transthoracic harmonic echo Doppler.
TLDR
Blood flow velocity evaluation in the LAD by means of transthoracic ED is feasible and reliable in detecting, locating, and assessing the severity of LAD stenosis. Expand
Assessment of functional significance of the stenotic substrate by Doppler flow measurements
TLDR
The determination of flow velocity at conditions of hyperemia and downstream from a lesion may provide misleading information on the functional significance of this stenosis since the microvascular, peripheral resistance - aside from stenosis severity - influences flow velocity distal to a given stenotic lesion. Expand
Value of coronary stenotic flow velocity acceleration in prediction of angiographic restenosis following balloon angioplasty.
TLDR
Following angioplasty, SV appears to be exquisitely sensitive to the changes experienced at the treated area without depending on the status of the microcirculation. Expand
