that may be applicable to
I35.1:
- Aortic incompetence, non-rheumatic
- Aortic valve regurgitation
- Collapsing pulse
Clinical Information
- Backflow of blood from the aorta into the left ventricle, due to imperfect functioning of the aortic valve
- Backflow of blood from the aorta into the left ventricle, owing to imperfect functioning of the aortic semilunar valve.
- Dysfunction of the aortic valve, with incomplete valve closure resulting in valvular regurgitation.
- Pathological condition characterized by the backflow of blood from the ascending aorta back into the left ventricle, leading to regurgitation. It is caused by diseases of the aortic valve or its surrounding tissue (aortic root).
- The backward flow of blood from the aorta into the left ventricle, owing to insufficiency of the aortic semilunar valve; it may be chronic or acute.
ICD-10-CM I35.1 is grouped within Diagnostic Related Group(s) (MS-DRG v39.0):
