What are the complications of aortic stenosis ?
• Left ventricular failure indicates poor prognosis unless the valve is replaced.
• Sudden death occurs in 10-20% of adults and I% of children. It has been rarely documented to occur
without prior symptoms. It is an uncommon event -probably <1% per year.
• Arrhythmias and conduction abnormalities include ventricular arrhythmias (more common than
supraventricular arrhythmias) and heart block (may occur because of calcification of conducting tissues).
• Systemic embolization is caused by disintegration of the aortic valve apparatus or by concomitant aortic atheroma.
• Infective endocarditis (in 10% of cases) should be considered when these patients present with
unexplained illness.
• Haemolytic anaemia.
