Population

50 patients who underwent coronary angiography (36 with adequate spectral Doppler recordings)

Comparison

Coronary flow velocity reserve measurement in… vs Coronary angiography

Design

Cross-sectional

Implication

Supports TTDE-CFVR for noninvasive RCA stenosis detection; leaves open prospective validation before clinical adoption.

Structured PICO

Does CFVR measured by TTDE accurately detect significant stenosis in the right coronary artery in patients undergoing coronary angiography?

Population

50 patients who underwent coronary angiography (36 with adequate spectral Doppler recordings)

Intervention

Coronary flow velocity reserve (CFVR) measurement in the posterior descending branch of the right coronary artery by transthoracic Doppler echocardiography (TTDE) during hyperemia induced by intravenous adenosine triphosphate

Comparator

Coronary angiography (reference standard for significant stenosis)

Outcome

Diagnostic accuracy (sensitivity and specificity) of CFVR <2.0 for predicting significant stenosis in the right coronary arterysurrogate

CFVR measurement in the right coronary artery by TTDE is a highly sensitive and specific noninvasive method for detecting significant coronary stenosis.
