Overview
People with aortic stenosis of any etiology are at risk for the development of infection of their stenosed valve, i.e. infective endocarditis and antibiotic prophylaxis should be considered.
Antibiotic Prophylaxis
To reduce the risk of developing infective endocarditis antibiotic prophylaxis should be considered prior to certain dental/medical/surgical procedures. Such procedures may include dental extraction, deep scaling of the teeth, gum surgery, dental implants, treatment of esophageal varices, dilation of esophageal strictures, gastrointestinal surgery where the intestinal mucosa will be disrupted, prostate surgery, urethral stricture dilation, and cystoscopy. Note that routine upper and lower GI endoscopy (i.e. gastroscopy and colonoscopy), with or without biopsy, are not usually considered indications for antibiotic prophylaxis.
Not withstanding the foregoing, the American Heart Association has recently changed its recommendations regarding antibiotic prophylaxis for endocarditis. Specifically, as of 2007, it is recommended that such prophylaxis be limited only to:
- Those with prosthetic heart valves
- Those with previous episode(s) of endocarditis.
- Those with certain types of congenital heart disease [1].
Vigorous Exertion
Given the risk of myocardial ischemia and sudden cardiac death, patients with severe aortic stenosis (< 1.0 cm2) should avoid strenuous physical activity including weightlifting and other activities that increase afterload.
