“…The operated patients may also have suboptimal FC in the presence of residual defects, ventricular dysfunction, chronotropic incompetence, tachyarrhythmia, heart block, SAH, PAH, PVH, prosthesis implantation, post-cardiac transplant deconditioning, IE, and co-existing multi-organ dysfunction [2,[22][23][24][25][28][29][30][31][32][33][34][35][36][37][38][39][40]. These patients need to undergo evaluation of cardiac disability based on a scoring system utilizing existing subjective and objective parameters, for the assessment of functional capacity [11][12][13]20]. DALY disability-adjusted life-year, UI uncertainty interval Heart disease categories, groups A, B, and C (Tables 1, 5, 6, 7, 8, 9) Inclusion of cardiac diseases in the HDC Gr A, B, and C is based on hemodynamic significance, type of HD, natural history, amenability to intervention, and overall outcome [2, 3, 5-7, 9, 13, 22-54].…”
