Key result
Transapical aortic valve implantation using the J-Valve system successfully treated severe quadricuspid aortic valve regurgitation, with normal valve function and no paravalvular leak at 6 months.
Why the study?
Due to the rarity of quadricuspid aortic valve, the treatment and prognosis of patients presenting with aortic regurgitation remain challenging.

TAVI using the J-Valve system is a feasible and effective treatment for patients with severe aortic regurgitation due to a quadricuspid aortic valve.
Supports TAVI feasibility in rare QAV regurgitation; leaves open durability and generalizability pending larger studies.
BACKGROUND: Quadricuspid aortic valve (QAV) is a rare congenital heart defect usually accompanied with different hemodynamic abnormalities. Due to the rarity of QAV, treatment and prognosis of QAV patients with aortic regurgitation still remain challenging. We here present the first case of a patient with severe QAV regurgitation who underwent successful treatment and performed favorable prognosis with transapical aortic valve implantation (TAVI) using J-Valve system. CASE PRESENTATION: A 62-year-old man experienced intermittent palpitation, shortness of breath and chest pain. Echocardiography revealed congenital QAV with massive aortic regurgitation and mild aortic stenosis, left ventricular enlargement. Aortic valve replacement was successfully performed with TAVI using J-Valve system. The postoperation and follow-up was uneventful. CONCLUSION: TAVI using J-Valve system has emerged as a new high success rate method for treatment of patients with simple non-calcified aortic valve insufficiency.

Luo et al. (2021) conducted a case report in Quadricuspid aortic valve with aortic regurgitation (n=1). Transapical aortic valve implantation using J-Valve system was evaluated on Procedural success and valve function. Transapical aortic valve implantation using the J-Valve system successfully treated severe quadricuspid aortic valve regurgitation, with normal valve function and no paravalvular leak at 6 months.
