Summary
Multiple congenital right ventricular diverticula (RVD) were incidentally found with constrictive pericarditis and heart failure. This rare association suggests RVD may cause pericardial disease, leading to heart failure.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Imaging
Background:
- Right ventricular diverticula (RVD) are rare congenital anomalies.
- Association of RVD with constrictive pericarditis is exceptionally rare, with only one prior case reported.
Purpose of the Study:
- To report a rare case of multiple congenital RVD associated with constrictive pericarditis and right heart failure.
- To highlight the potential causative role of RVD in pericardial disease.
Main Methods:
- Case report of a patient incidentally diagnosed with RVD during surveillance CT.
- Utilized serial CT, echocardiography, and cardiac magnetic resonance imaging (CMR) for diagnosis and characterization.
- Diagnostic criteria included imaging features of diverticula (trabeculation, contractility) and signs of constrictive physiology.
Main Results:
- Identified multiple RVDs, hepatic congestion, and pericardial calcification.
- Echocardiography showed supranormal diastolic velocities and septal bounce, indicative of constrictive physiology.
- CMR confirmed four RVDs, moderate RV dysfunction, and preserved LV function.
Conclusions:
- RVD can be associated with pericardial thickening and calcification.
- RVD may be a causative factor in the development of constrictive pericarditis and subsequent heart failure.

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

3.0K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

01:27Heart Failure I: Introduction
720
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
