Important Features 1.Undiagnosed and Unrepaired Congenital Heart Diseases are common in Adolescents or Adults 2.Cyanotic or Complex Congenital Heart Diseases are Rare Insufficient neonatal screening Lack of knowledge (patients / physicians) Limited hospital accessibility

Problems 1.Referral for Surgery is Limited – Cardiac surgery is available only in Mahosot Hospital, performed by foreign volunteer doctors (from western countries) – No cardiac surgery team in the Children’s Hospital – Post-operative outcome is unknown 2.Lack of Sedation System – EchoCG in the Children’s Hospital: Time- and Effort-consuming work 3.Economic and Social Situation – Patients/Parents cannot afford medical/surgical costs 4.Lack of Pathologic / Microbiologic / Serologic Laboratories – Routine laboratory tests are impossible or limited
