Adult congenital heart disease (ACHD) is a defect in the structure of the heart that is present at birth. Although it is a congenital condition, ACHD does not always display symptoms at birth. ACHD comes in numerous forms, with symptoms and treatments varying depending on the type of defect and the severity of the condition.
Problems with the heart’s structure can include a hole in the heart wall, complications with the blood vessels and blood flow and issues with the heart valves.
Symptoms vary depending on age, the number of heart defects an individual is born with, the type of defect and the severity of the condition. Some cases of ACHD may not cause any symptoms, but others can be complex and life-threatening, requiring comprehensive treatment. The signs and symptoms may include:
The following tests may be performed to diagnose ACHD:
The electrical signals in the heart are recorded during this test. ECGs can tell how fast or slow the heart is beating and can detect irregular heartbeats (arrhythmias).
X-rays of the chest can reveal changes in the heart's size and shape.
During this test, blood oxygen levels can be estimated by a small sensor attached to the finger.
Ultrasounds (sound waves) create images of the heart in motion during this test. Echocardiograms can provide information about blood flow through the heart and heart valves. You can also have an echocardiogram while exercising, usually on a bike or treadmill.
Transesophageal echocardiograms can provide more detailed images of the heart. Transducers are guided down a flexible tube through the throat and into the tube connecting the mouth and stomach (esophagus).
A treadmill or stationary bike is used during these tests to monitor the heart's rhythm. An exercise test can reveal how the heart reacts to physical activity.
During these tests, images of the chest and heart are captured. X-rays are used in cardiac CT scans, while a cardiac MRI uses magnetic fields and radio waves.
In this test, blood pressure and blood flow are measured in the heart. Catheters are gently inserted into blood vessels, typically in the groin and up to the heart, by a physician. In order to guide the catheter to the correct position, X-rays are used.
These procedures involve inserting a thin tube (catheter) into a blood vessel and using it to perform a variety of tasks, such as closing a hole in the heart or widening a narrow vessel.
These can help manage symptoms, lower blood pressure and improve heart function.
This can correct a defect, promote blood flow, or redirect blood. In severe cases, a patient might require a heart transplant.
This procedure involves providing additional oxygen to the body through a variety of means, such as using a small tube that delivers oxygen through the nose, a face mask, or a mechanical ventilator (breathing machine).
This relaxes smooth heart muscles and keeps the ductus arteriosus (a blood vessel normally closed after birth) open, which promotes circulation.
Care of the Critically Ill Surgical Patient (CCrISP) is a two-day, interactive course, which includes mandatory, pre-course e-learning. It covers the practical skills and knowledge that health care professionals need to effectively care for surgical patients, including those who are deteriorating or at risk of doing so.
