Abstract A 39-year-old male patient from a county health facility
presented to our department with a one-year history of progressive
exertional chest tightness (NYHA class III-IV), which resolved
completely within five to six minutes of rest. Both motion and static
imaging results revealed a rare solitary Quadricuspid aortic valve (QAV)
with severe aortic valve regurgitation. The QAV was replaced with
mechanical prosthetic valve via mini-superior sternotomy on
cardiopulmonary bypass machine. The patient was reviewed a month after
operation, and assessment revealed that he had reverted to NYHA class-I.
A rare congenital lesion such as QAV, repair may not be the best option
due to lack of long-term data on longevity. Additionally, choice of a
mechanical prosthetic valve guarantees unwanted re-operations associated
with possible failure of bioprosthetic valves.
