中国首例！华西完成顶级心脏手术，全程出血10ml

TL;DR - West China Hospital performed China’s first reported transfemoral-transseptal mitral valve-in-valve replacement combined with the BATMAN leaflet-translocation technique. The minimally invasive procedure treated a high-risk 72-year-old while avoiding predicted outflow obstruction and limiting blood loss to about 10 mL.

• Preoperative CT-based 3D reconstruction predicted near-certain left ventricular outflow tract obstruction with conventional valve-in-valve replacement.
• Surgeons used a guidewire and balloon to reposition the deteriorated valve leaflet before implanting the new valve in the beating heart.
• Transesophageal ultrasound guided the transseptal puncture, leaflet traversal, balloon expansion, and valve placement.
• The key procedure took about 2.5 hours; the patient walked the next day and was discharged after seven days.
