Study Notes
Tricuspid Valve Disease Overview
- Tricuspid valve disease includes two main conditions: tricuspid stenosis and tricuspid regurgitation.
Tricuspid Stenosis
- Characterized by fibrotic and stiff valve leaflets that do not open properly.
- Leads to decreased blood flow from the right atrium to the right ventricle during ventricular diastole.
- Commonly caused by rheumatic heart disease, which often occurs after rheumatic fever linked to streptococcal infections.
- In rheumatic heart disease, auto-antibodies lead to inflammation and fibrosis of the valve tissue.
- Tricuspid stenosis often co-occurs with aortic and mitral valve involvement.
Tricuspid Regurgitation
- Occurs when valve leaflets are floppy and fail to seal properly, causing backward flow of blood into the right atrium during systole.
- Possible causes include:
- Rheumatic heart disease, which can lead to fibrosis affecting valve sealing.
- Pulmonary hypertension, which causes right ventricular dilation and stretches the tricuspid valve annulus, compromising seal.
- Infective endocarditis, particularly due to Staphylococcus aureus, leading to vegetative growths that erode the valve.
- Ebstein's anomaly, a congenital condition where tricuspid valves are malformed and positioned too low in the ventricle, preventing proper sealing.
- Papillary muscle rupture following myocardial infarction, leading to loss of tension on valve leaflets and regurgitation.
Clinical Features of Tricuspid Stenosis
- Increased right atrial volume and pressure due to poor blood flow into the right ventricle.
- Leads to right heart failure signs such as:
- Jugular venous distension from backflow into the superior vena cava.
- Hepatomegaly and ascites from inferior vena cava congestion.
- Pedal edema in lower extremities.
- Dilation of the right atrium increases the risk of arrhythmias like atrial fibrillation and flutter.
- Potential compression of adjacent structures like the esophagus, leading to dysphagia.
Murmur Characteristics
- The tricuspid stenosis murmur occurs during diastole, primarily between S2 and S1 heart sounds.
- Observed as an "opening snap" followed by a diastolic rumble, usually audible at the left parasternal border (4th intercostal space).
Conclusion
- A thorough understanding of tricuspid valve disease necessitates recognizing the differences in pathophysiology, causes, clinical manifestations, and auscultation findings for each condition.### Mechanisms to Accentuate Murmurs
- Increase venous return to enhance heart sounds; more blood to right atrium increases murmur intensity.
- Actions to increase venous return:
- Inspiration (deep breathing)
- Squatting
- Leg raises
- Decrease venous return via:
- Standing
- Valsalva maneuver which can reduce murmur intensity.
Tricuspid Regurgitation Overview
- Tricuspid regurgitation leads to backward blood flow into the right atrium during ventricular systole, causing right ventricle volume overload.
- Right ventricular dilation occurs due to chronic volume overload, resulting in systolic dysfunction and further regurgitation.
- Symptoms include:
- Elevated end-systolic volume
- Right heart failure effects (e.g., jugular venous distention, pedal edema, hepatomegaly, ascites).
- An S3 heart sound may develop due to rapid ventricular filling.
Murmur Characteristics
- Holo-systolic murmur characteristics:
- Occurs through the entire systolic phase.
- Best heard at the left sternal border and mid-sternal area.
- Increased intensity with inspiration termed Carvallo's sign, indicating enhanced right-sided blood flow.
Diagnosis of Tricuspid Disorders
- Murmurs help in distinguishing between tricuspid stenosis (diastolic murmur with a snap) and tricuspid regurgitation (holo-systolic murmur).
- Echocardiography provides crucial diagnostic insights.
- Tricuspid stenosis may show thickened, fibrotic valves and reduced blood flow.
- Tricuspid regurgitation may display valve abnormalities or regurgitation jets.
Treatment Strategies
- Focus on managing right heart failure.
- Fluid and sodium restriction as initial management for mild cases.
- Diuretics (e.g., furosemide) for fluid overload; compression stockings for pedal edema.
- Balloon valvuloplasty indicated for mild to moderate tricuspid stenosis to open the valve.
- Valve replacement considered for severe cases or those unresponsive to balloon valvuloplasty.
Valve Replacement Options
- Mechanical valves:
- Highly thrombogenic, requiring lifelong anticoagulation (usually warfarin).
- Suitable for patients under 65 or those with existing atrial fibrillation.
- Bioprosthetic valves:
- Lower thrombogenicity, requiring anticoagulation for only 3 months post-surgery.
- Higher risk for prosthetic valve endocarditis; may require prophylactic antibiotics (e.g., amoxicillin).
Conclusion
- Management of tricuspid valve diseases revolves around recognizing symptoms, understanding murmur characteristics, performing accurate diagnostics, and correctly administering treatment strategies based on individual patient circumstances.

- Mechanical valves are highly thrombogenic, necessitating lifelong anticoagulation (often warfarin), suitable for patients under 65 or those with atrial fibrillation.
- Bioprosthetic valves have lower thrombogenicity, requiring only 3 months of anticoagulation post-surgery.
- Bioprosthetic valves pose a higher risk for prosthetic valve endocarditis, often necessitating prophylactic antibiotics like amoxicillin.
Conclusion
- Effective management of tricuspid valve diseases hinges on recognizing symptoms, understanding murmur characteristics, accurate diagnostics, and tailored treatment based on individual patient needs.
Tricuspid Valve Disease Overview
- Tricuspid valve disease comprises tricuspid stenosis and tricuspid regurgitation.
Tricuspid Stenosis
- Involves fibrotic and stiff leaflets that impede opening.
- Results in diminished blood flow from the right atrium to the right ventricle during diastole.
- Predominantly caused by rheumatic heart disease, occurring post-rheumatic fever from streptococcal infections.
- Auto-antibodies in rheumatic heart disease induce inflammation and fibrosis in valve tissues.
- Often coexists with aortic and mitral valve conditions.
Tricuspid Regurgitation
- Characterized by floppy leaflets that cannot seal adequately, allowing blood to flow back to the right atrium during systole.
- Causes include:
- Rheumatic heart disease leading to valve fibrosis.
- Pulmonary hypertension causing right ventricular dilation, stretching the tricuspid annulus.
- Infective endocarditis, notably from Staphylococcus aureus, creating vegetative growths on the valve.
- Ebstein's anomaly, a congenital defect where the tricuspid valve is malformed.
- Rupture of papillary muscles after myocardial infarction impairs valve leaflet tension.
Clinical Features of Tricuspid Stenosis
- Right atrial volume and pressure increase due to impaired blood flow.
- Symptoms of right heart failure manifest as:
- Jugular venous distension due to backflow into the superior vena cava.
- Hepatomegaly and ascites from inferior vena cava congestion.
- Pedal edema in lower limbs.
- Increased right atrial dilation raises the risk for arrhythmias, including atrial fibrillation and flutter.
- Compression of nearby structures, such as the esophagus, may lead to dysphagia.
Murmur Characteristics
- Diastolic murmur associated with tricuspid stenosis occurs between S2 and S1.
- Described as an "opening snap" followed by a diastolic rumble, hearable at the left parasternal border (4th intercostal space).
Mechanisms to Accentuate Murmurs
- Enhancing venous return increases murmur intensity:
- Actions include deep breathing (inspiration), squatting, and leg raises.
- Reducing venous return diminishes murmur intensity:
- Achieved by standing or performing the Valsalva maneuver.
Tricuspid Regurgitation Overview
- Causes backward blood flow into the right atrium during ventricular systole, leading to right ventricle volume overload.
- Chronic overload results in right ventricular dilation and systolic dysfunction.
- Symptoms include elevated end-systolic volume and right heart failure signs (e.g., jugular venous distention, pedal edema, hepatomegaly, ascites).
- Development of an S3 heart sound may indicate rapid ventricular filling.
Murmur Characteristics of Tricuspid Regurgitation
- Holo-systolic murmur persists throughout systole.
- Best detected at the left sternal border and mid-sternal area.
- Enhanced intensity during inspiration, known as Carvallo's sign, correlates with increased right-sided blood flow.
Diagnosis of Tricuspid Disorders
- Distinguishing between tricuspid stenosis (diastolic murmur with a snap) and regurgitation (holo-systolic murmur) is critical.
- Echocardiography provides essential diagnostic details:
- Tricuspid stenosis may show thickened, fibrotic valves with reduced flow.
- Tricuspid regurgitation often reveals valve abnormalities and regurgitation jets.
Treatment Strategies
- Primary focus is on managing right heart failure.
- Initial management includes fluid and sodium restriction in mild cases.
- Diuretics (e.g., furosemide) assist with fluid overload; compression stockings may relieve pedal edema.
- Balloon valvuloplasty may be performed for mild to moderate tricuspid stenosis to improve valve function.
- Severe cases or those non-responsive to balloon valvuloplasty may require valve replacement.
Valve Replacement Options
- Mechanical valves are highly thrombogenic, necessitating lifelong anticoagulation (often warfarin), suitable for patients under 65 or those with atrial fibrillation.
- Bioprosthetic valves have lower thrombogenicity, requiring only 3 months of anticoagulation post-surgery.
- Bioprosthetic valves pose a higher risk for prosthetic valve endocarditis, often necessitating prophylactic antibiotics like amoxicillin.
Conclusion
- Effective management of tricuspid valve diseases hinges on recognizing symptoms, understanding murmur characteristics, accurate diagnostics, and tailored treatment based on individual patient needs.
