The treatment of systemic hypertension (HTN) in patients with Aortic stenosis (AS) requires a careful balance of lowering the systemic blood pressure without compromising vital organ perfusion and worsening of the symptoms of AS. Treatment of systemic HTN is beneficial because the combination of HTN and AS provides additional overload to the left ventricle. This leads to secondary Left ventricular hypertrophy (LVH), which has been shown to increase cardiovascular risks and mortality and thus early presentation of symptoms of AS. Additionally, presence of HTN may affect the accurate assessment of AS. Different treatment options are available, however no specific treatment guidelines have been established for patients with concomitant AS and HTN. Improved control of HTN is the key to prevent symptom progression and inadvertent early surgery. Angiotensin converting enzyme inhibitors (ACEi) and Angiotensin receptor blockers (ARB) appear to be beneficial. Reassessment of the aortic valve by echocardiography is recommended after HTN is well controlled before deciding on aortic valve replacement (AVR).
