Table 3. Calcifications of other cardiovascular structures in aortic dissection patients with and without media calcifications.

Calcification in:	Presumed media calcifications in the aorta (N = 22)	Non-specific or no calcifications in the aorta (N = 47)	P-value for difference
Coronary arteries; N (%)	21 (95%)	37 (79%)	0.07
Splenic artery; N (%)	15 (68%)	15 (32%)	0.005
Aortic valve; N (%)	7 (38%); 3 prosthesis	15 (34%); 3 prosthesis	0.53
Mitral valve or annulus; N (%)	7 (32%)	1 (2%)	<0.001

Differences are tested using Chi-square tests.
