ABSTRACT
PURPOSES:
A retrospective analysis was performed to compare the pathological findings and aortic root Z-score in patients with and without connective tissue disease (CTD).METHODS:
Twenty-two patients {47.5 [15-85] years old, 18 males} underwent surgery for aortic root dilatation without aortic dissection 10 {40 [16-59] years old} with CTD and 12 {57.5 [15-85] years old} without CTD (non-CTD; p = 0.049). Systemic hypertension (p = 0.043) and the degree of preoperative aortic regurgitation (p = 0.017) were higher in the non-CTD patients than in the CTD patients.RESULTS:
The diameters of the sinotubular junction (STJ) (p = 0.048) and ascending aorta (Asc.Ao.) (p = 0.020) and the Z-scores of the STJ (p = 0.027) and Asc.Ao. (p = 0.009) were significantly higher in the non-CTD patients than in the CTD patients. The degree of translamellar mucoid extracellular matrix accumulation (T-MEMA) of the Asc.Ao. was significantly higher in the non-CTD patients than in the CTD patients (p = 0.037) and was significantly correlated with the Z-scores of the aorta (R = 0.746, p < 0.01 in the sinus of Valsalva and R = 0.382, p = 0.031 in the Asc.Ao.), although there was no significant correlation between the diameter of the STJ and that of Asc.Ao.CONCLUSIONS:
In non-CTD patients, not only the aortic root but also Asc.Ao. tended to dilate with age, and a significant correlation between the Z-scores of the aorta root and the Asc.Ao. and the degrees of T-MEMA was observed.Palabras clave
