From the Guidelines
A left atrial (LA) myxoma typically presents with a low-pitched, rumbling diastolic murmur, often referred to as a "tumor plop," which is usually heard at the apex 1.
Key Auscultation Findings
- A mid-diastolic murmur may be present, similar to that heard in mitral stenosis, as the tumor obstructs blood flow through the mitral valve 1
- The murmur can be either middiastolic or presystolic, similar to tricuspid or mitral stenosis (MS) 1
Variability in Murmur Characteristics
- The intensity and timing of these murmurs can vary depending on the size and mobility of the myxoma, as well as the patient's cardiac output and rhythm
- The murmur may be affected by respiration, with left-sided murmurs usually being louder during expiration 1
- Positional changes, such as standing or squatting, may also impact the intensity of the murmur 1
From the Research
Auscultation Findings of a Left Atrial (LA) Myxoma
There are no research papers provided that directly discuss the auscultation findings of a Left Atrial (LA) Myxoma.
Related Auscultation Findings
However, the provided studies discuss various auscultation findings related to heart conditions:
- Diastolic murmurs in non-obstructive hypertrophic cardiomyopathy 2
- Diastolic sounds and murmurs associated with mitral valve prolapse 3
- The etiology of the Austin Flint murmur 4
- Systolic murmurs radiating from the apex of the heart to the neck 5
- Improving competency in auscultation among nursing students 6
Key Points
- The studies provided do not directly address the auscultation findings of a Left Atrial (LA) Myxoma
- Auscultation findings can vary depending on the specific heart condition
- Diastolic murmurs, sounds, and systolic murmurs are discussed in the context of different heart conditions
- Improving auscultation skills is important for early detection and recognition of deteriorating patients 6
