The aim of this study is to analyze patients with bilateral CTS to identify patients with high-risk features or “red flags” for ATTR-CA, identify if systematic screening was done for ATTR-CA and define opportunities for improved detection. Methods: Out of >5000 patients with bilateral CTS evaluated in a single tertiary care center in Southeast Michigan (2010-2016), we retrospectively studied a focused population of patients: men > 50 years and women > 60 years old with bilateral CTS and atrial fibrillation (n = 295). Baseline demographic, comorbidities, and electrocardiographic and echocardiographic findings were analyzed. A high-risk group suspicious for ATTR-CA was identified as patients with bilateral CTS, atrial fibrillation, and concomitant “red flags” including heart failure and left ventricular hypertrophy. Results: Out of 295 patients, 51.2% were female, 75.6% were White, and 22.4% were African American. Upon comparing the high-risk group (n = 67) with the remaining study population (n = 228), both diagnosis of ATTR-CA and mortality were higher among the high-risk group (7.5% vs 0.4% and 43.3% vs 24.6%, respectively, P = 0.003). Conclusions: A substantial number of bilateral CTS patients had additional “red flags” warranting formal evaluation for ATTR-CA;however, systematic evaluation for cardiac amyloidosis was not performed in many patients. This emphasizes that Multidisciplinary collaboration is needed to create a systematic workflow and to raise awareness amongst cardiologists and other physicians for suspecting ATTR-CA in bilateral CTS patients who have additional “red flags”.展开更多
