Materials and Methods
A total of 56 patients; 33 females (60%), 23 males (40%) were operated
for CAVSD in our clinic between 2009 and 2019. The demographic and
surgical data of the patients with a median age of 18.19±29,9 months
(2-180), the male and female numbers with ratios of 33 males (60%) and
23 females (40%), and the mean weight of 9.87±7.96 kg (3.3-41) are
summarized in Table 1.
In preoperative echocardiography, 46 patients were determined to be
Rastelli type A (82,2%), 7 patients were type B (12,5%), 3 patients
were type C ( 5,3%). The mean VSD diameter was found to be 10.23 ± 4.47
mm (3-23). Preoperative LAVV regurgitation was determined to be moderate
and severe in 28 and 9 patients, respectively while right AV valve
regurgitation was also found in 24 and 9 patients, respectively. There
was a mitral cleft in all patients. There was no preoperative left
ventricular outflow truck obstruction (LVOTO) in any of our patients.
Additional anomalies are presented in Table 2.
Before total correction, 2 patients underwent BT shunt surgery, and 6
patients underwent pulmonary banding in the other centers.
As surgical techniques, cannulation of the ascending aorta after
standard median sternotomy, bicaval venous cannulation, and moderate
hypothermia were applied, and antegrade blood cardioplegia was used. The
MSP technique was applied to 37 (66%) patients, and the TPT was applied
to 19 (34%) patients. Mitral cleft repair was performed in all
patients. Additional valve repair was performed on the left
atrioventricular valve (LAVV) in 16 patients and the right
atrioventricular valve (RAVV) in 16 patients. The conventional
single-patch technique was not used in any of our patients.
Both patient groups were compared in terms of age groups, male-to-female
ratio, VSD diameter, CPB and aortic ACC time, intubation time, length of
ICU and hospital stay, drainage level, blood product usage amounts,
mortality and morbidities such as postoperative left and right valve
regurgitation, heart failure, infection, chylothorax, and
cerebrovascular events.
The long-term results of the study were evaluated over 45 patients who
could be followed up for 73,2 + 4,06 (22-128) months meanly.
