Abstract
We experienced two cases of postoperative iatrogenic aorto-right atrial fistula (ARAF)
after tricuspid valve repair (TVR) using minimally invasive cardiac surgery (MICS)
technique. In both the cases, the flow of ARAF passed through the sinus of Valsalva
near the noncoronary cusp (NCC)/right coronary cusp (RCC) commissure or NCC to right
atrium. The quality of the fine needle used in the MICS technique may be inferior
to that used in conventional surgery; ARAF after TVR could be a unique pitfall with
the MICS technique.
