Aorto-septal angle, isolated basal septal hypertrophy, and systolic murmur in 122 cats
Systolic murmurs in the absence of cardiac structural abnormalities are common in cats. Narrow aorto-septal angle (AoSA) and septal remodeling can be a cause of a systolic murmur in elderly human beings. The aim of this study was to measure the AoSA in cats and to investigate the association between...

| description | Systolic murmurs in the absence of cardiac structural abnormalities are common in cats. Narrow aorto-septal angle (AoSA) and septal remodeling can be a cause of a systolic murmur in elderly human beings. The aim of this study was to measure the AoSA in cats and to investigate the association between the AoSA and the presence of a murmur and isolated basal septal hypertrophy (IBSH).
The study population comprised 122 cats.
A physical exam, blood pressure measurement, chest radiographs, and echocardiography were performed.
A systolic murmur was audible in 39/122 cats. A difference between cats with and without a murmur was found for age (P=0.0001), interventricular basal septal thickness (BIVSd) (P=0.004), AoSA (P=0.003), aortic (P |

The study population comprised 122 cats.
A physical exam, blood pressure measurement, chest radiographs, and echocardiography were performed.
A systolic murmur was audible in 39/122 cats. A difference between cats with and without a murmur was found for age (P=0.0001), interventricular basal septal thickness (BIVSd) (P=0.004), AoSA (P=0.003), aortic (P<0.0001), and pulmonic (P=0.021) flow velocity, the presence of IBSH (P<0.0001), and systolic anterior motion of the mitral valve (P=0.0002). More than 50% of cats with a murmur had an AoSA ≤122°. Less than 25% of the cats with an AoSA ≥137° had a murmur. The AoSA narrowed 0.55°/year of age (P<0.001), whereas the BIVSd increased 0.11 mm/year of age (P<0.0001); the BIVSd increased as the AoSA narrowed. In all cats with AoSA < 120°, IBSH was present.
This study demonstrates that the probability of having a systolic murmur in cats is increased by the presence of a narrow AoSA. Aging was associated with a narrower AoSA and a thicker basal septum; these findings might represent an age-related heart remodeling.</description><identifier>ISSN: 1760-2734</identifier><identifier>EISSN: 1875-0834</identifier><identifier>DOI: 10.1016/j.jvc.2023.03.002</identifier><identifier>PMID: 37037177</identifier><language>eng</language><publisher>Netherlands: Elsevier B.V</publisher><subject>Animals ; blood pressure ; Cardiac murmur ; Cardiomyopathy ; Cat Diseases ; Cats ; chest ; echocardiography ; Echocardiography - veterinary ; elderly ; Feline ; heart ; Heart Murmurs - veterinary ; Humans ; hypertrophy ; Hypertrophy - veterinary ; probability ; Septal remodeling ; Sigmoid septum ; Systolic Murmurs - veterinary ; Ventricular Septum</subject><ispartof>Journal of veterinary cardiology, 2023-04, Vol.46, p.30-39</ispartof><rights>2023 Elsevier B.V.</rights><rights>Copyright © 2023 Elsevier B.V.
