Transapical aortic valve replacement for quadricuspid aortic valve with severe aortic regurgitation which caused multiorgan failure

Background We present the case of a patient who underwent successful transapical aortic valve implantation in a severe quadricuspid aortic valve (QAV) with severe regurgitation and multiorgan failure. Case Summary A 57‐year‐old man experienced intermittent palpitation and shortness of breath for 6 months. The condition deteriorated in the past month and caused multiorgan failure. The echocardiography and computed tomography angiography revealed severe aortic regurgitation due to congenital QAV. The aortic valve replacement was successfully performed in this high‐risk patient using a J‐Valve system. Postoperation and follow‐up were uneventful. Conclusion The J‐Valve system effectively treated QAV regurgitation with good clinical outcomes in this case.
