Coronary angiography also showed feeding arteries arising from the left circumflex (LCX) and left anterior descending vessels (LAD) [Figure 1]. However, an unusual single continuous jet with a peak velocity of 0.9 m/s was seen from LA roof into the LA chamber near the opening of right pulmonary vein [Figure 3 and Video 1].

The aforementioned findings were confirmed by the surgeon intraoperatively.
