Research on pediatric DCM remains surprisingly scarce. The primary objective of the study was to evaluate the clinical profile and outcomes of pediatric DCM and the secondary objective was to study the predictors of outcome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and Results:<\/jats:title>\n                    <jats:p>We enrolled all patients with cardiomyopathy who presented to us between 1990 and 2020 and were younger than 18 years. During the 30 year study period, we identified 233 cases of pediatric cardiomyopathy. One hundred and nineteen (51%) cases had DCM. This retrospective cohort was analyzed to study their outcome and the possible predictors of outcome. Nearly, 8% presented in the neonatal period, and 37% in infancy. The most common mode of presentation was dyspnea on exertion (71%). Ninety three patients presented in heart failure (78%). The median left ventricular dimension z score in diastole was 4.3 (range 2.5\u20139.06). The median left ventricle (LV) ejection fraction was 31%. Seventy two percent of this cohort were on angiotensin converting enzyme inhibitors, 40% on aldosterone antagonists, and 47% on beta blockers. One third had syndromic, metabolic, genetic, or any secondary cause identified. Twenty seven patients satisfied the three tiered clinical classification for the diagnosis of probable acute myocarditis. Over a mean follow up of 3.29 years, 27% were lost to follow up. Among the remaining patients who were on follow up (n = 86), 39 (45%) died, 31 (36%) recovered, and 16 (18%) had persistent LV dysfunction. Heart Failure was the most common cause of death. Eight patients in this cohort (4.2%) had thromboembolic phenomena. Nine had sustained ventricular arrhythmias and six had atrial\/junctional arrhythmias. Among the various risk factors studied, only infantile onset had a significant relationship with death or ventricular arrhythmias (P value\u2013 0.05). The 5 year survival rate of DCM patients was 59%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>A reasonably good percentage of our population showed recovery of the left ventricular function (36%). Only infantile onset had a significant relationship with death or ventricular arrhythmias.
