Most people think of heart disease as blocked arteries, heart attacks, or high blood pressure. Few realize that bacteria circulating in the bloodstream can settle on the heart itself, gradually destroying its valves and sending infected clots throughout the body.
That condition is called infective endocarditis, and it remains one of the most dangerous infections physicians encounter.
Unlike many emergencies that announce themselves dramatically, endocarditis often begins with vague symptoms that resemble dozens of common illnesses. A patient develops a fever that won't go away. They feel exhausted. They have body aches, chills, or unexplained weight loss. Some are treated repeatedly for the flu, a viral illness, or a urinary tract infection while the infection continues to damage the heart.
By the time the correct diagnosis is made, the patient may have suffered a stroke, developed heart failure, or require emergency open-heart surgery to replace a destroyed valve.
At Bounds Law Group, we represent patients and families throughout Florida who have suffered catastrophic injuries because serious medical conditions were not diagnosed in time. Delayed diagnosis of infective endocarditis is one of the most complex—and often preventable—forms of medical malpractice.

A Heart Valve Infection Doesn't Stay in the Heart
Endocarditis occurs when bacteria or, less commonly, fungi enter the bloodstream and attach to the lining of the heart or one of its valves.
Once attached, the microorganisms begin forming clumps called vegetations. These infected masses continue to grow, damaging the valve and interfering with the heart's ability to function normally.
Pieces of these vegetations can also break away and travel through the bloodstream.
If they reach the brain, they may cause a stroke.
If they lodge in the kidneys, spleen, or other organs, they can cause severe infections and permanent damage.
Without prompt treatment, endocarditis can be fatal.
According to the American Heart Association, infective endocarditis is a life-threatening infection that requires early recognition and aggressive treatment with intravenous antibiotics and, in some cases, heart surgery.

The Symptoms Often Develop Slowly
One reason endocarditis is frequently missed is that patients rarely appear critically ill during the early stages.
Instead, symptoms often develop gradually over days or weeks.
Common complaints include:
- Persistent fever
- Chills
- Night sweats
- Fatigue
- Muscle and joint pain
- Shortness of breath
- Unexplained weight loss
- Poor appetite
- Weakness
As the infection progresses, additional findings may develop, including heart murmurs, swelling in the legs, or signs that infected clots have traveled elsewhere in the body.
Because these symptoms are so nonspecific, patients often seek care multiple times before anyone suspects an infection involving the heart.
Certain Patients Face Greater Risk
Although anyone can develop endocarditis, certain medical conditions make it more likely.
Risk factors include:
- Artificial heart valves
- Previous endocarditis
- Congenital heart defects
- Intravenous drug use
- Cardiac implantable devices
- Long-term intravenous catheters
- Recent invasive medical procedures
- Poor dental health in certain high-risk patients
These risk factors do not guarantee that a patient has endocarditis.
They do, however, raise the level of concern when someone presents with persistent fever and no obvious source of infection.
Where the Diagnosis Begins to Slip Away
Many delayed diagnosis cases begin with a reasonable initial impression.
The patient is treated for:
- Influenza
- COVID-19
- Viral syndrome
- Pneumonia
- Bronchitis
- Urinary tract infection
- Sinus infection
Antibiotics may temporarily improve symptoms without eliminating the bacteria growing on the heart valve.
That temporary improvement can create a false sense that the correct diagnosis has been made.
Meanwhile, the infection continues damaging the heart.
In other cases, abnormal blood cultures are dismissed as contamination rather than recognized as evidence of a dangerous bloodstream infection.
The Heart Often Gives Important Clues
A careful physical examination remains an essential part of diagnosing endocarditis.
Providers may detect:
- A new heart murmur
- Fever
- Skin findings caused by small emboli
- Tiny hemorrhages beneath the fingernails
- Signs of heart failure
- Neurological deficits suggesting stroke
None of these findings alone confirms endocarditis.
Taken together, however, they often point providers toward a diagnosis that requires urgent investigation.
Blood Cultures and Echocardiograms Can Save Lives
When endocarditis is suspected, physicians have several important diagnostic tools available.
These commonly include:
- Multiple blood cultures obtained before antibiotics
- Complete blood work
- Echocardiography, particularly transesophageal echocardiography (TEE)
- Electrocardiography
- CT or MRI when embolic complications are suspected
Blood cultures frequently identify the specific bacteria responsible for the infection.
An echocardiogram may reveal vegetations attached to the heart valves, valve destruction, or abscess formation.
According to the Infectious Diseases Society of America (IDSA), obtaining appropriate blood cultures before beginning antibiotic therapy is one of the most important steps in accurately diagnosing bloodstream infections, including infective endocarditis.

Every Day Without Treatment Allows More Damage
Unlike many bacterial infections that respond quickly to oral antibiotics, endocarditis usually requires prolonged intravenous antibiotic therapy.
Some patients also require emergency surgery because the infection has destroyed one or more heart valves.
Delays increase the likelihood of:
- Valve destruction
- Congestive heart failure
- Stroke
- Brain abscess
- Kidney damage
- Septic emboli
- Persistent bloodstream infection
- Death
The longer bacteria remain attached to the heart, the greater the opportunity for permanent injury.
When a Stroke Is Actually a Heart Infection
One of the more surprising ways endocarditis is discovered is after a patient suffers an unexplained stroke.
An infected vegetation breaks loose from the heart and travels directly to the brain.
The stroke itself receives immediate attention.
Only later do physicians realize the stroke was actually caused by an untreated heart infection.
In these situations, diagnosing the stroke is only part of the challenge.
Unless the underlying infection is identified and treated, additional emboli may continue traveling throughout the body.
What Florida's Standard of Care Requires
Endocarditis is an uncommon condition.
Healthcare providers are not expected to suspect it in every patient with a fever.
However, when persistent symptoms, abnormal blood cultures, heart murmurs, risk factors, or other clinical findings reasonably suggest a heart valve infection, providers are expected to investigate appropriately.
Medical malpractice claims in Florida are governed by Chapter 766 of the Florida Statutes, which establishes the legal standards applicable to healthcare negligence claims.
The statute is available here:
https://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0700-0799/0766/0766.html
Depending on the clinical circumstances, appropriate care may include obtaining blood cultures, ordering echocardiography, consulting infectious disease or cardiology specialists, initiating appropriate intravenous antibiotics, and arranging timely surgical evaluation when indicated.
Whether the standard of care was met depends on the facts of each individual case and requires review by qualified medical experts.
Reconstructing the Timeline Often Explains the Outcome
Endocarditis rarely develops overnight.
Instead, the diagnosis is often missed over multiple medical visits.
Our attorneys carefully review:
- Primary care records
- Emergency department records
- Hospital admissions
- Blood culture reports
- Echocardiograms
- Cardiology consultations
- Infectious disease consultations
- Surgical records
- Pathology reports
- Neurological records when strokes occur
Medical experts evaluate when endocarditis should reasonably have been suspected and whether earlier treatment would likely have prevented heart valve destruction, stroke, or other permanent injuries.
Frequently, the opportunity to change the outcome existed days—or even weeks—before the diagnosis was finally made.
The Effects Can Last Long After the Infection Is Gone
Even after the infection has been successfully treated, many patients continue living with its consequences.
Some require artificial heart valves that must be monitored for the rest of their lives.
Others suffer permanent neurological deficits after embolic strokes.
Many face months of rehabilitation following open-heart surgery, prolonged hospitalization, and intravenous antibiotic treatment.
For families who lose a loved one, the knowledge that earlier diagnosis may have prevented the outcome can be especially difficult to accept.
