Pattern of congenital heart disease and access to tertiary cardiac care in Malaysia

This prospective, descriptive study was carried out to determine the pattern and the type of congenital heart disease seen in the Paediatric Departments in 4 government hospitals. The accessibility of surgical or transcatheter interventional treatment was also assessed. Consecutive new patients seen for suspected congenital heart disease from 1/1/95 till 31/12/95 (Group I) were registered. Records of patients seen from 1/1/95 to 31/8/95 (Group Ia) were reviewed 6 months after presentation to determine the nature of treatment received. Group II were cardiac patients who were first seen prior to the year 1995 and had undergone cardiac surgery or transcatheter interventional procedures in 1995. Of the 375 patients registered in the 4 hospitals, 250 were new patients and 125 were patients first seen prior to 1995 and had surgery or transcatheter interventional procedures in 1995. Of the 250 new patients, 83.2% had acyanotic cardiac lesions and 16.8% had cyanotic lesions. Ventricular septal defect was the commonest lesion, constituting 37.2%, followed by patent arterial duct (18.8%) and atrial septal defects (9.6%). At 6 month review, access to close-heart surgery or transcatheter interventional treatment were readily available. However, for patients with ventricular septal defects, 42.1% who required closure were still waiting for surgery 6 months after presentation. Of the 4 patients with Fallot's Tetralogy who required surgery, 2 had modified Blalock-Taussig shunt and 2 were awaiting surgery. In 1995, a total of 204 cardiac procedures were performed, there were 114 (55.9%) open heart procedures, 50 (24.5%) surgical ligation of the arterial duct, 28 (13.7%) modified Blalock-Taussig shunts, 11 (5.4%) transcatheter duct occlusion and 1 (0.5%) balloon valvuloplasty. The mean age of Fallot's Tetralogy repair was 6.4 years. No corrective surgery was performed for patients with complex cardiac lesions from the 4 hospitals in 1995. In conclusion, the pattern of congenital heart disease was similar to that seen world wide. Except for patent arterial duct, access to surgical treatment was inadequate.
