I cannot create the summary of the requested article because the article titled "Coming Radiotracer Shortage; Dedicated Cardiometabolic Training; New PFA Catheter" from MedPage Today is not found in the search results provided. The search results only contain articles in Czech and Slovak about cardiac amyloidosis from Czech and Slovak sources, but not the article you listed. If you would like me to create a summary of a specific article, please provide the full text or relevant search results that contain it.
