Summary
This case report details a rare ventriculo-atrial defect, a type of Gerbode defect, caused by infective endocarditis near a prosthetic aortic valve. It highlights a novel cause of this uncommon cardiac defect.
Area of Science:
- Cardiology
- Infectious Diseases
- Surgical Pathology
Background:
- Ventriculo-atrial defects are rare cardiac abnormalities.
- Infective endocarditis can lead to abscess formation and subsequent defects.
- Gerbode defects, specifically, are uncommon and typically involve native cardiac tissue.
Observation:
- A 71-year-old male presented with a ventriculo-atrial defect.
- The defect originated from the aortic root adjacent to a bioprosthetic aortic valve implanted 4 years prior.
- Infective endocarditis was identified as the cause, leading to inflammation and a paravalvular prosthetic defect.
Findings:
- This case represents a novel third type of Gerbode defect, specifically a ventriculo-atrial defect secondary to inflammation of a paravalvular aortic prosthetic defect.
- The defect resulted from infective endocarditis affecting the aortic root and prosthetic valve.
Implications:
- This report expands the known etiologies of Gerbode defects to include paravalvular prosthetic complications.
- Understanding this rare presentation is crucial for accurate diagnosis and surgical management of similar cases.
- Highlights the importance of considering prosthetic valve complications in infective endocarditis.

1.6K
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...

580
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

1.1K
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
