These result in dysfunctional cellular oxidative phosphorylation and ATP production, affecting organs with high-energy requirements such as the heart, brain and skeletal muscle. Cardiac involvement is common affecting one third of patients and includes left ventricular hypertrophy, conduction disease, Wolff-Parkinson-White syndrome, and dilated cardiomyopathy. Due to the variability in the clinical presentation, a multiparametric approach incorporating clinical, biochemical, histological\/histochemical and genetic criteria is required to make the diagnosis. Cardiologists should be aware of the clinical red flags and imaging findings and how to differentiate mitochondrial cardiomyopathy from other causes of left ventricular hypertrophy. Cardiovascular magnetic resonance imaging is a highly sensitive tool for depicting myocardial abnormalities to aid in both the diagnosis of patients presenting with left ventricular hypertrophy, and in the assessment of cardiac involvement in patients with a known diagnosis of mitochondrial myopathy, as this is an independent predictor of morbidity and early mortality. The most common CMRI findings include increased maximal LV wall thickness and mass and non-ischaemic subepicardial and midwall LGE, most commonly affecting the basal inferolateral or lateral wall. Future studies should consider integrating late gadolinium enhancement imaging into risk prediction models to enhance stratification of major adverse cardiac events such as heart failure and arrhythmia. As our understanding of mitochondrial disease evolves, integrating advanced imaging with molecular diagnostics will be essential for early detection of disease, improved risk prediction and outcomes.<\/jats:p>","DOI":"10.1093\/ehjimp\/qyaf134","type":"journal-article","created":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T13:02:46Z","timestamp":1764248566000},"source":"Crossref","is-referenced-by-count":2,"title":["Cardiac magnetic resonance findings in mitochondrial disease: a guide for clinicians"],"prefix":"10.1093","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2720-6933","authenticated-orcid":false,"given":"Rhys","family":"Gray","sequence":"first","affiliation":[{"name":"Department of Inherited Cardiovascular Diseases, Barts Heart Centre , W Smithfield, London EC1A 7BE ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasiliki","family":"Kantartz\u0131","sequence":"additional","affiliation":[{"name":"Department of Inherited Cardiovascular Diseases, Barts Heart Centre , W Smithfield, London EC1A 7BE ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis R","family":"Lopes","sequence":"additional","affiliation":[{"name":"Department of Inherited Cardiovascular Diseases, Barts Heart Centre , W Smithfield, London EC1A 7BE ,","place":["UK"]},{"name":"Institute of Cardiovascular Science, University College London , Gower St, London WC1E 6BT ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantinos","family":"Savvatis","sequence":"additional","affiliation":[{"name":"Department of Inherited Cardiovascular Diseases, Barts Heart Centre , W Smithfield, London EC1A 7BE ,","place":["UK"]},{"name":"Institute of Cardiovascular Science, University College London , Gower St, London WC1E 6BT ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Westwood","sequence":"additional","affiliation":[{"name":"Department of Inherited Cardiovascular Diseases, Barts Heart Centre , W Smithfield, London EC1A 7BE ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,11,28]]},"reference":[{"key":"2025112813011728500_qyaf134-B1","doi-asserted-by":"crossref","first-page":"1421","DOI":"10.1016\/j.jacc.2022.08.716","article-title":"Cardiac outcomes in adults with mitochondrial diseases","volume":"80","author":"Savvatis","year":"2022","journal-title":"J Am Coll Cardiol"},{"key":"2025112813011728500_qyaf134-B2","doi-asserted-by":"crossref","first-page":"1132","DOI":"10.1056\/NEJMra1012478","article-title":"Monogenic mitochondrial disorders","volume":"366","author":"Koopman","year":"2012","journal-title":"N Engl J Med"},{"key":"2025112813011728500_qyaf134-B3","doi-asserted-by":"crossref","first-page":"3023","DOI":"10.1093\/eurheartj\/ehs275","article-title":"Cardiac involvement in mitochondrial DNA disease: clinical spectrum, diagnosis, and management","volume":"33","author":"Bates","year":"2012","journal-title":"Eur Heart J"},{"key":"2025112813011728500_qyaf134-B4","doi-asserted-by":"crossref","first-page":"254","DOI":"10.1016\/j.ajhg.2008.07.004","article-title":"Pathogenic mitochondrial DNA mutations are common in the general population","volume":"83","author":"Elliott","year":"2008","journal-title":"Am J Hum Genet"},{"key":"2025112813011728500_qyaf134-B5","first-page":"385","article-title":"Mitochondrial cardiomyopathy: pathophysiology, diagnosis, and management","volume":"40","author":"Meyers","year":"2013","journal-title":"Tex Heart Inst J"},{"key":"2025112813011728500_qyaf134-B6","doi-asserted-by":"crossref","first-page":"2886","DOI":"10.1093\/eurheartj\/ehv307","article-title":"Long-term cardiac prognosis and risk stratification in 260 adults presenting with mitochondrial diseases","volume":"36","author":"Wahbi","year":"2015","journal-title":"Eur Heart J"},{"key":"2025112813011728500_qyaf134-B7","doi-asserted-by":"crossref","first-page":"585","DOI":"10.1097\/00019052-200310000-00004","article-title":"Mitochondrial disorders","volume":"16","author":"Zeviani","year":"2003","journal-title":"Curr Opin Neurol"},{"key":"2025112813011728500_qyaf134-B8","doi-asserted-by":"crossref","first-page":"25","DOI":"10.3389\/fcvm.2016.00025","article-title":"Mitochondrial cardiomyopathies","volume":"3","author":"El-Hattab","year":"2016","journal-title":"Front Cardiovasc Med"},{"key":"2025112813011728500_qyaf134-B9","doi-asserted-by":"crossref","first-page":"114","DOI":"10.1093\/eurjhf\/hfp186","article-title":"Prevalence and natural history of heart disease in adults with primary mitochondrial respiratory chain disease","volume":"12","author":"Limongelli","year":"2010","journal-title":"Eur J Heart Fail"},{"key":"2025112813011728500_qyaf134-B10","doi-asserted-by":"crossref","first-page":"674","DOI":"10.1212\/WNL.0b013e3181d0ccf4","article-title":"Cardiac involvement is frequent in patients with the m. 8344A &gt;
