In 520 of 843 patients prospectively enrolled in TRAMI, baseline LA diameter were reported [median (interquartile range) LA diameter in tertiles: 44 (40\u201346) mm, 51 (48\u201353) mm and 60 (55\u201366) mm]. Larger LA diameters were significantly associated with secondary aetiology of mitral regurgitation, lower ejection fraction, larger left ventricle, male sex and atrial fibrillation (all P\u2009&amp;lt;\u20090.05). Technical success was not different across tertiles (96%, 95.4% and 98.4%, respectively; P = 0.43) as were major in-hospital cardiovascular and cerebral adverse events (mortality, myocardial infarction or stroke: 1.8%, 1.2% and 4.4%, respectively; P = 0.11 across tertiles). However, 4-year mortality significantly increased with larger LA diameter (32.9%, 46.4% and 51.7%, respectively; P\u2009&amp;lt;\u20090.01), as did hospitalization in survivors (60%, 67.6% and 78.9%, respectively; P\u2009&amp;lt;\u20090.05). The association between LA diameter and outcome remained significant after multivariable adjustment including baseline left ventricular end-diastolic diameter.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Left atrial enlargement is a strong and independent predictor of adverse long-term outcome after transcatheter mitral valve repair.
