Key result
Echocardiographic assessment showed significantly decreased tricuspid annular motion in ARVC patients versus controls, though 4 of 15 patients had normal right ventricular dimensions.
Why the study?
Do M mode and pulsed tissue Doppler echocardiographic techniques detect abnormal right ventricular function in patients with ARVC compared to healthy controls?
Observational (n=40)
No
Do M mode and pulsed tissue Doppler echocardiographic techniques detect abnormal right ventricular function in patients with ARVC compared to healthy controls?
Tissue Doppler and M mode echocardiography of the tricuspid annulus can detect early, non-specific signs of right ventricular dysfunction in ARVC patients, even when standard RV dimensions appear normal.
No takes yet. Share an insight, caveat, or question.
May aid early RV dysfunction detection in ARVC despite normal dimensions; hypothesis-generating and requires prospective validation before clinical use.
L. Lindström (2001) conducted an observational in Arrhythmogenic right ventricular cardiomyopathy (ARVC) (n=40). Echocardiographic assessment (M mode and pulsed tissue Doppler) vs. Healthy controls was evaluated on Tricuspid annular motion amplitude and tissue Doppler velocity patterns. Echocardiographic assessment showed significantly decreased tricuspid annular motion in ARVC patients versus controls, though 4 of 15 patients had normal right ventricular dimensions.
