Sequelae of ventricular septal defect surgery may include residual shunts, severe arrhythmias, and valvular regurgitation.
Ventricular septal defects are a type of congenital heart disease and generally require aggressive treatment once diagnosed, with treatments ranging from interventional stenting to open heart surgery.
Usually there are few complications after ventricular septal defect surgery, but the most common complication is residual shunt, which is a small defect after surgery, usually asymptomatic can be left untreated, but if it is a large residual shunt, you need to consider another surgery when obvious symptoms appear.
Secondly, more serious arrhythmias such as third-degree AV block may occur, and if the heart rate is slow, a pacemaker is often required to maintain normal cardiac function.
Another complication that may occur is valve regurgitation, especially aortic regurgitation, which is usually due to unsupported localized valves underneath the valve, resulting in prolapse of the labrum. This complication usually has a greater impact on cardiac function and often requires another surgery.
If you feel unwell, you should seek medical attention and follow the treatment prescribed by your doctor.
