Valve (Definition)

A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more

When to restart is controversial depending on the prosthetic valve(mitral vs aortic), atrial fibrillation, enlarge atrial chamber and systolic ventricular dysfunction.

Pat. With mitral prosthetic heart valve and develope sah.When we restart anticoagulant and we start by lmwh or warfarin?

No good answer: I'm presuming sah is "subarachnoid hemorrhage". The answer depends on if the mitral valve is bioprosthetic or mechanical (i presume mechanical in a 36 yo) and if the rhythm is sinus or atrial fib (common in this setting). There are no controlled trials to guide this. There is no right answer. Be guided by the cardiologist's experience that you know and trust.Good luck with this difficult situation. ...Read more

Can you advise me if having piercings with a prosthetic heart valve. subacute bacterial endocarditis?

Can you advise me if having piercings with a prosthetic heart valve. subacute bacterial endocarditis?

No clear guidelines: Prosthetic valve indicates increased risk of endocarditis. Even under current, stricter AHA guidelines, you would need SBE prophylaxis before high-risk procedures, like dental cleaning/extractions, tonsillectomy, I&D of abscesses. No clear data about body piercings, so different MDs have different approaches. Discuss with your MD, but clean the area very well & care for the site after. Take care! ...Read more
