Description
Xia Chen and colleagues report a rare heart birth defect in a 2026 case study of a 44-year-old man. A thin membrane above the lung valve had fused with one valve leaflet, forming a pouch that choked blood flow out of the right heart, a shape not reported before. The man came in with growing breathlessness on exertion, and scans showed severe narrowing with a peak pressure gap of 170 mmHg across the valve.
At surgery the valve had three leaflets with thick, fused joins, and the team freed those joins to relieve the block. The patient recovered well and reported no symptoms at one month. Single cases cannot set a rule for others. The report gives surgeons a named shape to watch for when a membrane and valve appear joined. It shows that freeing the fused tissue can restore flow.
