Back to Podcast Episodes422. Diagnosis of Transthyretin Amyloid Cardiomyopathy (ATTR-CM) with Dr. Venkatesh Murthy
Drs. Rick Ferraro and Sneha Nandy discuss ‘Diagnosis of ATTR Cardiac Amyloidosis’ with Dr. Venkatesh Murthy. In this episode, we explore the diagnosis of ATTR cardiac amyloidosis, a condition once considered rare but now increasingly recognized due to advances in imaging and the availability of effective therapies. Dr. Venkatesh Murthy, a leader in multimodality imaging, discusses key clinical and laboratory features that should raise suspicion for the disease. We also examine the role of nuclear imaging and genetic testing in confirming the diagnosis, as well as the importance of early detection. Tune in for expert insights on navigating this challenging diagnosis and look out for our next episode on treatment approaches for cardiac amyloidosis! Audio editing for this episode was performed by CardioNerds Intern, Julia Marques Fernandes.

Pearls: – Diagnosis of Transthyretin amyloid cardiomyopathy
1. Recognizing the Red Flags – ATTR cardiac amyloidosis often presents with subtle but telling signs, such as bilateral carpal tunnel syndrome, low-voltage ECG, and a history of lumbar spinal stenosis or biceps tendon rupture. If you see these features in a patient with heart failure symptoms, think amyloidosis!
2. “Vanilla Ice Cream with a Cherry on Top” – On strain echocardiography, apical sparing is a classic pattern for cardiac amyloidosis. While helpful, it’s not foolproof—multimodal imaging and clinical suspicion are key!
3. Nuclear Imaging is a Game-Changer – When suspicion for cardiac amyloidosis is high à a positive PYP scan with SPECT imaging (grade 2 or 3 myoc
