Septic endocarditis and indwelling pulmonary artery catheters
JAMA
|September 4, 1975
Summary
A case of Staphylococcus aureus endocarditis was linked to a pulmonary artery catheter. However, a review found no increased risk of left-sided endocarditis from right-sided heart catheter use, though right-sided vegetations can form.
Area of Science:
- Cardiology
- Infectious Diseases
- Pathology
Background:
- Indwelling pulmonary artery catheters are used in critical care.
- Septic endocarditis is a serious infection of the heart lining.
- Idiopathic cardiomyopathy is a heart muscle disease of unknown cause.
Purpose of the Study:
- To investigate the potential association between pulmonary artery catheter use and endocarditis.
- To determine if right-sided heart catheterization increases the risk of left-sided endocarditis.
Main Methods:
- Case report of Staphylococcus aureus infection following pulmonary artery catheterization.
- Retrospective review of 438 autopsy reports with indwelling pulmonary catheters.
- Comparison with 493 autopsy reports prior to catheter use.
Main Results:
- Staphylococcus aureus was identified in catheter, blood, and sputum cultures.
- Autopsy revealed septic endocarditis of the right side of the heart.
- No association found between right-sided catheter use and left-sided endocarditis.
Conclusions:
- While right-sided heart catheterization may lead to thrombotic vegetations, it does not appear to increase the risk of left-sided endocarditis.
- Infection and embolization are potential complications of right-sided endocardial vegetations.
- Careful monitoring and sterile techniques are crucial during pulmonary artery catheterization.

01:16Heart Valves
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

01:15Thoracic Aorta
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
01:26Pneumothorax-I
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

01:15Aortic Regurgitation I: Introduction
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...
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:26Aneurysm III: Interprofessional Care
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...
