Interventions were done in half of the patients. Median follow up was 23.5\u2009months.

Median age was 36\u2009years, females (68.3%) and low income (55.5%). Multivalvular disease was found in 116 (40%) patients, atrial fibrillation (31.4%), stroke\/transient ischaemic attack (18.9%) and heart failure class III\u2013IV (44.1%). Median (IQR) duration of disease was 3 (4) years, secondary prophylaxis (27.7%) and oral anticoagulants use (62.3%). In multivariable analysis, the risk of death among patients on medical was 3.07 times higher than those on interventional treatment (crude HR 3.07, 95% CI 1.43\u20136.56,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.004), 2.44 times higher among patients with arrhythmias versus without arrhythmias (crude HR 2.44, 95% CI 1.19\u20134.49,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.015) and 2.13 times higher among patients with multivalvular than single valve disease (crude HR 2.13, 95% CI 1.09\u20134.16,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.026).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Intervention is carrying low mortality compared to medical treatment.
