Aortic valve stenosis — of any cause — can be a serious condition because it can weaken the heart. 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 these changes 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
