Cardiac Scintigraphy and Echocardiography Assessment in the Diagnosis of Transthyretin Cardiac Amyloidosis
The International Journal of Cardiovascular Imaging(2023)
摘要
The aim is to evaluate the diagnostic yield of echocardiography and [99mTc]Tc-DPD scintigraphy in the detection of amyloid cardiomyopathy (CM) and define potential prognostic echocardiographic parameters. 133 patients were retrospectively studied, from 2016 to 2021, with a mean age of 80.2 ± 7.5 years. The final diagnosis was established according to international consensus. Patients had a transthoracic echocardiogram (TTE) and [99mTc]Tc-DPD scintigraphy; RWT, E/e, LS, TAPSE, SAB, and IWT scores were calculated. All patients with ATTR-CM were classified into 3 prognostic stages and were compared with Perugini grades and echocardiographic parameters. CM was confirmed in 85 cases (63.9
