Summary
Aortic valve repair (AVr) for infective endocarditis (IE) is safe and effective in selected patients. While durable for tricuspid valves, bicuspid valves may require replacement, especially with severe insufficiency.
Area of Science:
- Cardiovascular Surgery
- Infectious Diseases
- Cardiac Valve Disease
Background:
- Infective endocarditis (IE) poses a significant threat, with treatment decisions for aortic valve (AV) involvement often debated.
- Surgical intervention for IE requires careful consideration of valve repair versus replacement.
Purpose of the Study:
- To retrospectively analyze a two-decade experience with aortic valve repair (AVr) in patients with IE.
- To evaluate long-term outcomes of AVr, focusing on valve configuration and patch techniques.
Main Methods:
- A single-center retrospective analysis of 42 patients undergoing AVr for IE between September 1998 and June 2017.
- Surgical techniques included leaflet patch repair, resuspension, and aortic annulus stabilization.
Main Results:
- Hospital mortality was low at 2.4%.
- Long-term survival was favorable, with no significant difference between tricuspid aortic valve (TAV) and bicuspid aortic valve (BAV) patients.
- Freedom from reoperation was significantly lower in BAV patients compared to TAV patients at 10 years (p=0.02).
- Bicuspid aortic valve (BAV), preoperative aortic insufficiency severity, and patch use in AVr predicted higher reoperation risk.
Conclusions:
- Aortic valve repair (AVr) is a safe, feasible, and effective option for selected IE patients.
- Repair durability is excellent for limited lesions and TAV, even with patch use.
- Reoperation is more common in BAV patients, particularly those with severe preoperative aortic insufficiency undergoing patch repair, suggesting valve replacement may be preferable in such cases.

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

01:25Endocarditis I: Introduction
252
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

01:15Aortic Regurgitation I: Introduction
272
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
