Causes of RVOT dysfunction after surgery
|Causes of RVOT dysfunction after surgery
Following are some important causes of progressive RVOT dysfunction after repair surgeries for congenital heart disease:
- Pulmonary regurgitation
- Stenosis at the conduit anastomotic site
- Somatic outgrowth
- Stenosis of pulmonary valve
- Kinking of the conduit
- Compression due to sternal deformity
- Intimal proliferation
- Calcification of the conduit
- Aneurysmal degeneration of the RVOT
Right ventricular outflow tract dysfunction is one of the most important long term sequelae of repair of Tetralogy of Fallot [1]. This can lead to exercise intolerance, cardiac arrhythmias and even sudden cardiac death. Percutaneous pulmonary valve implantation has been used in the management of this condition.
