Cardiac Diagnostics

This channel includes news, videos, podcasts and other content on new technology innovations for cardiac diagnostic systems and techniques. This includes laboratory testing, blood tests including troponin testing, electrocardiogram (ECG) systems, point of care testing systems, genetic testing, cardiac patient monitoring devices including wearable sensors, and studies showing new ways to diagnose heart diseases.

Dr. Markus Krane, deputy director of the Cardiac and Vascular Surgery Unit at the DHM helped compile an atlas of the heart and discovered myosin binding protein H-like (MYBPHL) occurs only in the atria of the heart. Researchers began using it as a blood test biomarker to assess the success of atrial fibrillation ablation procedures.

With the advent and optimization of nuclear scintigraphy protocols using bone-avid radiotracers, cardiac amyloidosis caused by transthyretin protein (ATTR) can now be diagnosed noninvasively without a costly tissue biopsy. The radiotracer 99mTc-pyrophosphate (99mTc-PYP) binds to deposited ATTR amyloid fibrils in the myocardium and can be visualized using planar and SPECT imaging. The image shows how SPECT allows the reader to distinguish between blood pool activity and radiotracer uptake.

With the advent and optimization of nuclear scintigraphy protocols using bone-avid radiotracers, cardiac amyloidosis caused by transthyretin protein (ATTR) can now be diagnosed noninvasively without a costly tissue biopsy. The radiotracer 99mTc-pyrophosphate (99mTc-PYP) binds to deposited ATTR amyloid fibrils in the myocardium and can be visualized using planar and SPECT imaging. This is Figure 2, showing how SPECT imaging allows the reader to distinguish between blood pool activity (ventricular cavity, etc) and myocardial activity and identify regional myocardial differences in radiotracer uptake.
