Variants of the pulmonary venous index: at the level of the pulmonary vein ostium (OstPVI), at the level of bifurcation PV (BifPVI), and the sum of the minimum cross-sectional areas of each pulmonary vein (minPVI) failure. ^∗-compare to OstPVI between survivors and dead groups. ^∗∗-compare to minPVI between survivors and dead groups.
