Aortic valve stenosis — of any cause — can be a serious condition. If the aortic valve is narrowed, the left ventricle has to work harder to pump a sufficient amount of blood into the aorta and onward to the rest of your body.

In response, the left ventricle may thicken and enlarge. At first, these adaptations help the left ventricle pump blood with more force. But eventually it's harder for the heart to maintain the blood flow to the body through the narrowed valve. Then you will start to experience symptoms. Eventually, the extra work of the heart can weaken the left ventricle — and your heart overall.

Left unchecked, aortic valve stenosis can lead to life-threatening heart problems, including:

  • Chest pain (angina)
  • Fainting (syncope)
  • Heart failure
  • Irregular heart rhythms (arrhythmias)
  • Cardiac arrest
