The author analyzed 99 patients with VSD weighting less than 10kg of body weight who underwent surgical correction from 1981 to 1992 at cardiovascular department of Hanyang University hospital.
Patients occupied 29.3% of total cases who were underwent surgical corrections for congenital heart diseases during that time. Of the 99 patients, 51 patients were male(52%) and 48 patients(48%) were female. Age ranged from 28 days to 36 months
with
mean age of 13.6 months. Mean body weight was 7.53kg. Acording to Kirklin's anatomical classification, type II defect was most common (61.6%). Associated amomaly was found in 48 patients(48.5%). Patent foramen ovale was most commonly associated
cardiac
anomaly(14.4%) and followed by atrial septal defect(12.1%), patent ductus arteriosus(10.1%).
Cardiac catheterization data were analysed. The most common range of Op/Os, Rp/Rs, Pp/Ps were above 3.0, 0.1-0.25, and above 0.75 respectively.
Among the indications of surgical correction there were pulmonary hypertension in 69 patients, congestive heart failure in 44 patients, frequent respiratory infection in 47 patients, growth retardation in 33 patients. The most common surgical
approach
and method for VSD closure were right atriotomy(48.3%) and darcron patch closure(93.3%).
Complication rate was 13.1%(13 cases), and overall motality was 17.1%(17 cases). The cause of death consisted of low cardiac output syndrome(11 cases), acute renal failure(3 cases), sepsis(2 cases) and pulmonary insufficiency(1 case) in oder of
frequency. (Korean J Thoracic Cardiovas Surg 1994; 27:650-5)
