Pulmonary artery hypertension in acyanotic congenital heart disease underwent transcatheter closure at dr. Soetomo hospital

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.
