Table 1:

The termination points of the ASV^a

ASV Termination Type	ASV Termination	Total (531 ASVs)
Type A	Venous angle	383	72.13%
Type B	ICV: anterior third	76	14.31%
	ICV: middle third	52	9.79%
	ICV: posterior third	1	0.19%
	ICV elongation (absent TSV)	20	3.77%
	LDV	5	0.94%
	MAV	15	2.82%
	Cavernous sinus	1	0.19%

Note:—MAV indicates medial atrial vein.

^aTypes A and B refer to the classification of ASV–ICV junction proposed by Türe et al (1997),³ and they differentiate between the ASV located at the venous angle (anteriorly) or beyond it (posteriorly).¹¹
