Over the last several decades there has been a remarkable change in the therapeutic strategy of congenital heart disease. Development of new tools and devices, accumulations of experience, technical refinement have positively affected the outcome of interventional treatment. Many procedures including atrial septostomy, balloon valvuloplasty, balloon dilation of stenotic vessel with or without stent implantation, transcatheter occlusion of abnormal vascular structure, transcatheter closure of patent arterial duct and atrial septal defect, are now performed as routine interventional procedures in many institutes. In diverse conditions, transcatheter techniques also provide complementary and additive role in combination with surgery. Intraoperative stent implantation on stenotic vessels, perventricular device insertion, and hybrid stage 1 palliative procedure for hypoplastic left heart syndrome have been employed in high risk patients for cardiac surgery with encouraging results. Transcatheter closure of ventricular septal defect has been performed safely showing comparable result with surgery. Investigational procedures such as percutaneous valve insertion and valve repair are expected to replace the role of surgery in certain group of patients in the near future. Continuous evolvement in this field will contribute to reduce the risk and suffering from congenital heart disease, while surgery will be still remained as a gold standard for significant portion of congenital heart disease.

Recent advances in the surgical treatment of congenital disorders of the heart have necessitated an accurate preoperative diagnosis. Right heart catheterization has become widely accepted as a research tool and diagnostic test to detect the heart diseases, especially in the congenital heart anomalies. Right heart catheterizations were carried out in 50 cases of congenital heart diseases at Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital, during the period of June, 1975 through September 1978. In age distribution, 27cases were below 10 years of age, 18 cases between 11 and 20, and 5 cases above 20 male to female ratio was 2.8:1. The distribution of congenital heart diseases was VSD [42%], TOF [36%], PDA [10%], ASD [8%], and PS[4%]. Of these, 44 cases [88%], were compatible with the clinical impressions that were made preliminarily before cardiac catheterization, and all the cases except 1 case of VSD was correlated well with the postoperative diagnosis. The right heart catheterization is considered to be reliable and accurate toll in the preoperative diagnosis of congenital heart diseases. These procedures caused complications such as left side hemiplegia [lcase], occlusion of the femoral artery [lcase], and transient ventricular tachycardia [1case], and so the complication rate of right heart catheterization was 6% [3 cases]. None of patients who have undergone right heart catheterization was died.

Between April, 1986 and July, 1991, 477 patients underwent open heart surgery with hypothermic cardiopulmonary bypass. There were 242 patients [50.7%] of acyanotic congenital anomalies, 34 patients [7.1%] of cyanotic congenital anomalies, and 187 patients [39.2%] of acquired heart diseases, 8 patients [1.7%] of coronary artery diseases, and 6 patients [1.3%] of mixed anomalies. Among the 276 congenital cardiac anomalies, 147 patients [53.3%] were male and 129 patients [46.7%] were female, ranged in age from 2 years to 58 years. Among the 187 acquired heart diseases, 72 patients [38.5%] were male and 115 patients [61.5%] were female, ranged in age from 10 years to 68 years. The common congenital defect were VSD and ASD in acyanotic cardiac patients, and TOF in cyanotic cardiac patients. Among the 187 acquired heart diseases, 180 patients underwent operation for cardiac valvular diseases, 4 patients were resected left atrial myxoma, and 3 patients underwent operation for aortic regurgitation with ascending aortic aneurysm. The operative mortality rate was 1.2% in acyanotic cardiac patients, 11.8% in cyanotic cardiac patients, and 6.9% in acquired cardiac patients, with overall mortality rate 4.2%.
