Pulmonary Artery Hypertension in Acyanotic Congenital Heart Disease Underwent Transcatheter Closure at Dr. Soetomo Hospital
Keywords:Pulmonary artery hypertension, acyanotic congenital heart disease, tricuspid regurgitation, transcatheter closure
Background: Pulmonary artery hypertension (PAH) is common complication of congenital heart disease.
Echocardiography before and after transcatheter closure procedure is needed for further evaluation.
Objective: To evaluate the PAH before and after transcatheter closure procedure by echocardiography at
Dr. Soetomo Hospital.
Methods: Medical record patients with acyanotic congenital heart disease with PAH and already done
transcatheter closure procedure in 2010 – 2014 were reviewed. Data taken were demographic, clinical,
and echocardiography. Tricuspid regurgitation pressure gradient (TRPG) was evaluated. Statistical analysis
using t test comparative study; P<0.05 was considered significant.
Results: There were 46 patients underwent transcatheter closure, ASD closure 22/46, VSD closure 16/46,
PDA closure 8/46 patients. Ten patients with PAH (10/46), 4/10 ASD, 4/10 PDA and 2/10 VSD. Boys were
6/10, median age was 60 (range 4-144 months). Median TRPG before procedure was 32.4 (range 25-43
mmHg). Median TRPG after procedure was 21.5 (range 15-26.9 mmHg). There was significant decreased in
PAH after transcatheter closure procedure (P=0.01).
Conclusion: Transcatheter closure procedure in acyanotic congenital heart disease was important for
decreasing the pressure gradient of PAH.
