“…The patient group had a significantly decreased E:A ratio compared with the normal subjects, and this could not be explained by differences in heart rate. Abnormal tricuspid inflow has been reported in one previous study of ARVC patients but results were only reported from six patients 27. Two of our patients showed a severely abnormal superior vena caval inflow pattern, with a peak systolic to diastolic ratio of < 1 indicating decreased ventricular compliance 28.…”

Objective-To evaluate new echocardiographic modes in the diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC). Design-Prospective observational study. Setting-University Hospital. Subjects-15 patients with ARVC and a control group of 25 healthy subjects. Methods-Transthoracic echocardiography included cross sectional measurements of the right ventricular outflow tract, right ventricular inflow tract, and right ventricular body. Wall motion was analysed subjectively. M mode and pulsed tissue Doppler techniques were used for quantitative measurement of tricuspid annular motion at the lateral, septal, posterior, and anterior positions. Doppler assessment of tricuspid flow and systemic venous flow was also performed. Results-Assessed by M mode, the total amplitude of the tricuspid annular motion was significantly decreased in the lateral, septal, and posterior positions in the patients compared with the controls. The tissue Doppler velocity pattern showed decreased early diastolic peak annular (E A ) velocity and an accompanying decrease in early (E A ) to late diastolic (A A ) velocity ratio in all positions; the systolic annular velocity was significantly decreased only in the lateral position. Four patients had normal right ventricular dimensions and three were judged to have normal right ventricular wall motion. The patient group had also a significantly decreased tricuspid flow E:A ratio. Conclusions-Tricuspid annular measurements are valuable, easy to obtain, and allow quantitative assessment of right ventricular function. ARVC patients showed an abnormal velocity pattern that may be an early but non-specific sign of the disease. Normal right ventricular dimensions do not exclude ARVC, and subjective detection of early changes in wall motion may be diYcult. (Heart 2001;86:31-38)

“…Ao contrário, nas formas ditas menores ou "frustras", os dados tornam-se de apreciação e reprodutibilidade variável na dependência da experiência do ecocardiografista. Muitos autores consideram que a ecocardiografia tem valor diagnóstico apenas nos casos com quadro clínico mais relevante [26][27][28][29][30] . Porém, Scognamiglio e col 31 sugerem que o ecocardiograma pode ser útil para o diagnóstico precoce da DAVD, mesmo em pacientes assintomáticos, devido à possibilidade de identificação de alterações morfológicas e na cinética ventricular direita.…”
