Insights
This study shows a new surgical technique for aortic valve regurgitation caused by cusp prolapse is effective. The procedure, involving cusp plication and annuloplasty, demonstrated good short-term results in patients with both tricuspid and bicuspid aortic valves.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Repair
- Echocardiography
Background:
- Aortic valve regurgitation (AVR) due to cusp prolapse requires effective surgical solutions.
- Traditional repair methods may have limitations for specific AVR etiologies.
Observation:
- Three adult patients (2 tricuspid, 1 bicuspid aortic valve) with AVR from cusp prolapse underwent a novel surgical repair.
- The procedure combined cusp plication via triangular cusp resection and subcommissural annuloplasty.
Findings:
- Intraoperative and immediate post-operative Doppler echocardiography showed trivial or less than I/IV aortic valve regurgitation.
- At a mean 15-month follow-up, patients maintained minimal regurgitation (I/IV for tricuspid, II/IV for bicuspid).
Implications:
- This combined surgical technique appears feasible and beneficial for AVR stemming from cusp prolapse.
- While long-term outcomes require further investigation, initial results suggest a promising therapeutic option.
Abstract:
Three adults, 2 with tricuspid aortic valve and 1 with bicuspid valve, underwent valvuloplasty for aortic valve regurgitation resulting from cusp prolapse. Surgical procedures consisted of combined cusp plication by triangular cusp resection and subcommissural annuloplasty. Doppler echocardiography revealed trivial aortic valve regurgitation intraoperatively and less than I/IV at discharge in all cases. After mean follow-up of 15 months, 2 tricuspid aortic valve patients remain I/IV regurgitation and II/IV in the bicuspid patient. Although long-term results remain unclear, our results show that this procedure is feasible and beneficial in patients with aortic valve regurgitation due to cusp prolapse.
