Comparison of two-dimensional echocardiographic and angiographic findings in arrhythmogenic right ventricular dysplasia.

Journal Article (Journal Article)

Comparison of 2-dimensional (2-D) echocardiographic and right ventricular (RV) angiographic findings was performed in 10 patients with arrhythmogenic RV dysplasia. Diagnosis was based on accepted electrocardiographic and angiographic criteria. Nine patients underwent invasive electrophysiologic study, which confirmed RV source of ventricular tachycardia (VT) in 7. Biopsy findings of RV dysplasia were available in 3 patients. Two-dimensional echocardiography and angiography corresponded closely when diffuse RV enlargement and hypokinesia were present. Such diffuse findings were not invariably present. Localized abnormalities consisting of bulging or sacculation of the RV wall were noted by both techniques, even in the absence of diffuse changes. Echocardiographic evidence of localized disease predicted the presence of similar lesions at angiography, but agreement as to specific location was poor. Subjectivity in interpreting subtle RV abnormalities by either technique and the inherent differences in information provided by the 2 methods probably account for the inconsistencies. In the patient with suspected arrhythmogenic RV dysplasia, 2-D echocardiographic evidence of diffuse RV enlargement, otherwise unexplained, strongly supports the diagnosis and angiography may be avoided. Isolated local changes seen by echocardiography should increase suspicion of RV dysplasia, but complementary angiographic study is warranted.
