Figuring out and protecting observe of the situation might assist decrease the danger for potential issues sooner or later.

  • Electrocardiogram. That is carried out to test the guts’s electrical rhythm.

  • Chest X-ray. These assist view the guts anatomy and lungs.

  • Cardiac CT or MRI. These are carried out if extra element is required concerning the valve, coronary heart, or aorta.

This usually is simply a brief measure. In most superior circumstances, your healthcare supplier would possibly suggest open coronary heart surgical procedure. The aortic valve can then get replaced or fastened. Some individuals with bicuspid aortic valve might be able to have TAVR (transcatheter aortic valve substitute). This process makes use of a catheter as an alternative of surgical procedure to interchange the valve.

Healthcare suppliers might use donor valves from cadavers for valve substitute. However more often than not, biologic valves comprised of tissue from a cow or a pig are used. Different instances, they use synthetic mechanical valves. Some synthetic valves require you to take blood thinners lifelong.
