One PET, Two PET – Endocarditis and Positron Emission Tomography

PETs. We all love them. I have two of those, if the pictures in my “about me” page are any indication as well as the main pic of this post. This post will not cover our beloved (and sometimes only) friends. No, we will be talking about positron emission tomography, an imaging modality we usually

Echo? Who, what, when, how? Role of echo modality in Staph aureus bacteremia.

I absolutely love this song. I tried to learn how to play it on guitar, but I think you may need 7 strings for it, at least when I checked back in the day. This week we are adding to last week’s topic and talking about when and what type of echo to get. There

Infective Endocarditis: A Journey Through Definitions

At any rate, at approximately one-quarter to twelve that night, I remember distinctly getting up from my chair and from the table, where my books lay, and taking off my suit coat. No sooner had I removed the left arm of my coat, than there was on the ventral aspect of my left wrist a

Query: A Journey from Ruminants to Heart Valves

Last post was all about dogs and their mouths. This time, is about cow placentas. At least to a certain extent. Coxiella burnetii is a gram negative organism that is known to cause a variety of diseases, however it is most commonly associated with culture-negative endocarditis. While it is generally a “wimpy” organism and not

The Lyon Heart – The Virulent Coagulase-Negative Staphylococcus

Coagulase negative staphylococcus are generally skin commensals we tend to ignore when they pop up in one set of blood cultures as they tend to represent contamination of the blood culture bottles rather than true bacteremia. The most commonly seen is Staphylococcus epidermidis. The reason they are called “coagulase negative staphylococcus” is these organisms, compared

According to the patient, he has been feeling unwell for the past month. He had a recent outpatient visit for dysuria, the UA was positive for leukocyte esterase.

When To Get A TEE for Staphylococcus Aureus Bacteremia

Staphylococcus aureus bacteremia is a cause of severe morbidity and mortality, especially when it is complicated by infective endocarditis. The mortality of Staphylococcus aureus bacteremia is 20% (1) and that of infective endocarditis due to Staph aureus is much higher. Guidelines for the treatment of MRSA SAB (2) recommends the use of echocardiography, with TEE

Enterococcal bacteremia and the risk of infective endocarditis – No Go

Enterococcal infections and bacteremia incidence have been increasing over the past decades, with enterococcal endocarditis representing 10% of all cases of infective endocarditis (1). This makes it the third most common organism implicated in IE, after Staphylococcus and streptococcus, and it is more prevalent in patients who are not drug abusers. Enterococcal bacteremia by itself

Surgery in Native Valve Infective Endocarditis

In general, this tends to be a tricky subject. Add that to the fact that there are varying recommendations from different societies, it becomes difficult to figure out the who and when (I assume the surgeons will figure out the how). Here, we will look at timing of surgical intervention in left sided native infective
