Final answer:
Conduction disturbances associated with TAVR can include bundle branch blocks (BBB), atrial fibrillation, atrioventricular block, and heart block. These disruptions in the heart's electrical signaling can lead to abnormal heartbeats and symptoms such as dizziness and fatigue. Close monitoring and management of these disturbances is important for patient care.
Step-by-step explanation:
Transcatheter aortic valve replacement (TAVR) is a procedure used to treat aortic valve stenosis, a condition in which the valve that controls blood flow from the heart's left ventricle to the aorta becomes narrow. Conduction disturbances can occur as a result of the TAVR procedure and may include bundle branch blocks (BBB), atrial fibrillation, atrioventricular block, and heart block.
In a bundle branch block, the electrical signals that control the heart's contractions are delayed or blocked. This can lead to an abnormal heartbeat and other symptoms. Atrial fibrillation is an irregular and fast heart rate that can cause blood clots, stroke, heart failure, and other problems. Atrioventricular block and heart block involve blockages in the electrical pathways between the atria and ventricles, resulting in a slow heart rate and potential symptoms such as dizziness, fainting, and fatigue.
Monitoring and managing conduction disturbances associated with TAVR is important to ensure optimal outcomes for patients. This may involve medication to control heart rate and rhythm, as well as close follow-up with the healthcare team to monitor any changes or complications.
