Insights
Papillary fibroelastomas, rare pediatric heart tumors, can occur on the tricuspid valve. Cardiac MRI effectively diagnosed this rare tumor in an infant, distinguishing it from a thrombus.
Area of Science:
- Cardiology
- Pediatric Oncology
- Diagnostic Imaging
Background:
- Papillary fibroelastomas are rare, benign primary cardiac tumors.
- They typically arise from heart valves but are uncommon in children.
- Tricuspid valve involvement is exceptionally rare, with limited pediatric cases reported.
Observation:
- An 11-month-old infant presented with a heart murmur detected since birth.
- Cardiac magnetic resonance imaging (CMR) was utilized for diagnostic evaluation.
- The imaging aimed to differentiate a potential cardiac mass from a thrombus.
Findings:
- A papillary fibroelastoma originating from the tricuspid valve was identified.
- This represents a rare instance of this tumor type in an infant.
- CMR provided crucial characterization of the cardiac mass.
Implications:
- This case highlights the utility of cardiac MRI in diagnosing rare pediatric cardiac tumors.
- It expands the understanding of papillary fibroelastoma presentation in infants.
- Early and accurate diagnosis is vital for appropriate management of pediatric cardiac masses.
Abstract:
Papillary fibroelastomas are benign primary cardiac tumors that usually arise from the valve apparatus and are rare in the pediatric population. Involvement of the tricuspid valve is even less common with only a few cases reported in the literature. Cardiac magnetic resonance imaging is a valuable examination that aids in differentiating a tumor from a thrombus. We present the case of an 11-month-old girl referred by her pediatrician to investigate a murmur noted since birth. To our knowledge, this is the first report of a pathologically proven papillary fibroelastoma arising from the tricuspid valve characterized by magnetic resonance imaging in an infant.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Correlation
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:
Heart 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...
