Objective:
To
understand the clinical manifestation of subarterial ventricular septal
defect (sVSD) and master the operation indication properly.
Methods: It was studied for 325
cases of sVSD by operation confirmation. To observe the relation of each
age group with patients who complicated pulmonary artery hypertension (PHA)
and aortic valve disease (AVD).（aortic valve regurgitation 、aortic value prolapse 、aortic sinus rapture ）and the relation between
the size of VSD with PAH and AVD.
Results: 1) 294 cases of sVSD was
checked by echocardiography. The positive was 90.4%. 2) The incidence and severe degree of
patients who complicated PAH were decreased with advancing age. When age<1
year, the incidence of PAH was 70%, decreased to 30% at 14 years. 3) It has a significant increase for
patient who complicated AVD with advancing age. The incidence of aortic
valve disease was 43.4% at 14 years. 4) The incidence and severe degree of PHV had evidently
increased with the advancing VSD, when the size of VSD >10mm, the severe
degree of PAH was up to 40% and it had evidently increased for patients who
complicated aortic valve disease with the advancing VSD was up to 38%. 5)
With the advancing VSD increasing, the incidence of complicated AVD was
increased when the size of VSD < 20mm, but decreased when the size of
VSD ≥ 20mm. The incidence rates of AVD were 28.3%, 41.2% and 8.3%
(P<0.05) respectively when the diameter of VSD < 10mm, ~20mm and ≥ 20mm. 6) Patch
operation of patients was 311 cases (95.7%). Cure rate of operation was
98.2%. Mortality was 1.8%. Operational effect was satisfied.
Conclusion: Due to anatomical
factor and hemodynamic characteristic, the natural closure of sVSD was rarely
achieved, serious complication was complicated,easily in the sVCD. So it is
suggested that when sVSD was diagnosed, the early operation was needed as
early as possible.
