Generally, heart blockers last a lifetime, so they don’t do anything after 30 or 40 years and don’t need to be replaced. If a patient has congenital heart disease, such as atrial septal defects, ventricular septal defects, and arterial ductus arteriosus, the heart blocker can be placed inside the heart through a minimally invasive procedure to block the defective part of the heart, thus achieving the goal of healing. Most blockers are made of nickel-titanium alloy, and when placed inside the heart, they are gradually encapsulated by the heart’s endothelial cells and become a part of the heart, which does not move around and is less likely to be easily damaged. Therefore, this kind of blocker can be used for a lifetime, even after 30 to 40 years, usually there will not be any problems, and do not need to be replaced. However, patients should pay attention to their diet, eat less spicy and stimulating food, and maintain a healthy lifestyle, go to bed early, get up early, try not to stay up late to avoid damage to the body, and go to the hospital for regular checkups.
