The natural history of left cardiac myxomas is thought to be of slowly growing tumours. Cardiac myxomas are a heterogeneous group with a variable growth rate. They present usually with stroke, valve obstruction, or non-specific symptoms. Surgical resection is the effective treatment.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>This case report describes a 56-year-old hypertensive and dyslipidaemic female, when she was admitted in January 1990, complaining of loss of appetite, aches, pains, and palpitations. Her workup included a transthoracic echocardiography and transoesophageal echocardiography, which showed a left atrial mass attached to the inter-atrial septum, highly suggestive of left atrial myxoma. She was referred for surgical removal of the left atrial mass. However, she was reluctant to undergo surgery as she felt better. The patient was followed-up for almost 30\u2009years with the left atrial mass confirmed as left atrial myxoma by cardiac magnetic resonance imaging. The left atrial mass became smaller in size and more calcified.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Cardiac myxomas are a group of heterogeneous tumours, thought to be slowly growing. The growth rate of cardiac myxomas prior to diagnosis is not well known, as the vast majority is treated with surgical resection immediately after diagnosis. Our case showed the natural progression of an unoperated smooth-surfaced left atrial myxoma followed-up for almost 30\u2009years, which slowly became smaller and more calcified.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytaa310","type":"journal-article","created":{"date-parts":[[2020,11,12]],"date-time":"2020-11-12T10:26:12Z","timestamp":1605176772000},"page":"1-5","source":"Crossref","is-referenced-by-count":6,"title":["30-year follow-up of an unoperated left atrial myxoma: a case report"],"prefix":"10.1093","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3061-2035","authenticated-orcid":false,"given":"Zeinelabdien","family":"Elsherif","sequence":"first","affiliation":[{"name":"King Abdulaziz Cardiac Center, King Abdulaziz Medical City for National Guard Health Affairs, PO Box 22490, Riyadh 11426, Saudi Arabia"},{"name":"King Saud bin Abdulaziz University for Health Science, P.O.
