We report a case study of a 70-year-old man on chronic immunosuppression who presented with sustained ventricular tachycardia and symptoms of acute systolic heart failure, both with poor response to standard measures. A decision to pursue endomyocardial biopsy established the diagnosis of GCM and lead to initiation of immunosuppressive therapy and a favourable outcome. Our case illustrates that a low threshold for endomyocardial biopsy in new onset heart failure can lead to actionable information even in patients of advanced age.<\/jats:p>","DOI":"10.1002\/ehf2.12756","type":"journal-article","created":{"date-parts":[[2020,7,9]],"date-time":"2020-07-09T11:40:06Z","timestamp":1594294806000},"page":"3165-3168","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Giant
