We aim to explore differences in the dimensions of the left ventricle and functional recovery in patients with TCM compared with patients with other forms of CM.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>We identified patients with reduced ejection fraction (\u226450%) and\/or atrial fibrillation or flutter with a left ventricular ejection fraction that improved from baseline (\u226515% in left ventricular ejection fraction at follow-up or normalization of cardiac function with at least 10% improvement). Patients were then divided into two groups: (A) TCM patients and (B) patients with other forms of CM (controls). Two hundred thirty-eight patients were included (31% female, 70 years median age), 127 patients had TCM, and 111 had other forms of CM. Patients with TCM did not significantly improve indexed left ventricular volume (LVEDVI) after treatment (60 [45, 84] mL\/m2 versus 56 [45, 70] mL\/m2, P = ns) compared with controls (67 [54, 81] mL\/m2 versus 52 [42, 69] mL\/m2, P &amp;lt; 0.001). Patients with TCM patients had significantly worse fractional shortening at baseline than controls (15.5 [12, 23] vs. 20 [13, 30], P = 0.01) and higher indexed left atrial volume (LAVI) at baseline than controls (48 [37, 58] vs. 41 [33, 51], P = 0.01) that remained dilated at follow-up (follow-up LAVI 41 [33, 52] mL\/m2). Good predictors of TCM were: normal LVEDVI (LVEDVI &amp;lt; 58 mL\/m2 (M) and &amp;lt; 52 mL\/m2 (F)) (odds ratio [OR] 5.2; 95% confidence interval [CI] 2.2\u201313.3, P &amp;lt; 0.001), fractional shortening &amp;lt; 30% (OR 3.5; 95% CI 1.4\u20139.2, P = 0.009), LAVI &amp;gt;40 mL\/m2 (OR 3.4; 95% CI 1.6\u20137.3, P = 0.001) and normal wall thickness left ventricle (OR 3.2; 95% CI 1.4\u20137.8, P = 0.008). 54% of patients with TCM demonstrated diastolic dysfunction at follow-up, without differences from controls (54% vs. 43%, P = ns). 21% of patients with TCM showed persistent heart failure symptoms at follow-up compared with 4.5% of controls, P = 0.004.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>TCM patients have a specific pattern of functional recovery with persistent remodelling of the left atria and left ventricle.
