Mild Tricuspid Prolapse and Its Connection to Autonomic Nervous System - Cardiology

Mild tricuspid valve prolapse with mild mitral regurgitation and autonomic nervous system involvement?


Hello, doctor.
I had blood tests and an echocardiogram done.
My blood results showed slightly elevated LDL cholesterol levels, and the echocardiogram indicated mild tricuspid valve prolapse and mild mitral valve regurgitation.
The doctor mentioned that there are no significant issues, but I might have some autonomic nervous system dysregulation.
Currently, I'm experiencing symptoms that are hard to describe.
Sometimes I feel a slight prickling sensation in my heart, which occasionally radiates to my right chest or back (with a bit of pain), but it's not severe—just noticeable.
Additionally, my hands and neck sometimes twitch (similar to eyelid spasms, visibly noticeable).
These occurrences are not very frequent, happening about once or twice a day, lasting from a few seconds to a minute.
Furthermore, I've been troubled by a tight, constricted feeling in my throat for nearly two months.
Eating does not affect it, but I can feel it when swallowing saliva.
I consulted an ENT specialist, and there were no abnormalities found.
The cardiologist suggested it might be related to psychological stress, but I don't feel particularly stressed, so I'm unsure what the issue might be.
Currently, the throat condition is the most bothersome.
Thank you.

Hello, we are human and it's natural to feel discomfort here and there.
If the examinations show nothing wrong, then there is nothing to worry about.
The symptoms mentioned are also not related to the heart, so don't worry.
Changhua Hospital cares about you.

Understanding the connection between mild tricuspid prolapse and the autonomic nervous system (ANS) is essential for comprehending the symptoms you are experiencing. Mild tricuspid prolapse is a common condition where the tricuspid valve does not close properly, which can lead to a slight backflow of blood. While this condition is often benign and may not require treatment, it can be associated with various symptoms, particularly when influenced by the autonomic nervous system.

The autonomic nervous system is divided into two main branches: the sympathetic and parasympathetic nervous systems. The sympathetic system is responsible for the "fight or flight" response, while the parasympathetic system promotes "rest and digest" functions. Dysregulation of the ANS can lead to a variety of symptoms, including palpitations, anxiety, and even physical sensations such as tingling or twitching in different parts of the body.

In your case, the symptoms you describe—such as the mild stabbing sensation in the heart, discomfort in the right chest and back, and the twitching of the hands and neck—could be manifestations of autonomic dysregulation. These sensations may not be directly caused by the tricuspid prolapse itself but rather by how your body is responding to stressors, whether they are physical, emotional, or psychological. The fact that your symptoms occur sporadically and are not severe suggests that they may be linked to transient changes in your autonomic nervous system's activity.

Moreover, the sensation of tightness in your throat, which you have experienced for nearly two months, can also be related to anxiety or stress, which can trigger a sympathetic response. This response can lead to muscle tension and discomfort in the throat area, often described as a "lump in the throat" sensation. Even in the absence of significant psychological stress, the body can react to perceived threats or discomforts, leading to these physical symptoms.

It is important to note that while mild tricuspid prolapse is generally not a cause for concern, it is crucial to monitor your symptoms and maintain regular check-ups with your healthcare provider. They can help determine if further evaluation is necessary, especially if your symptoms persist or worsen. Additionally, lifestyle modifications such as stress management techniques, regular exercise, and a balanced diet may help alleviate some of the symptoms associated with autonomic dysregulation.

In summary, while mild tricuspid prolapse itself may not be the direct cause of your symptoms, the interplay between this condition and the autonomic nervous system could explain the sensations you are experiencing. It is advisable to continue working with your healthcare providers to explore these symptoms further and to consider holistic approaches to managing your overall well-being.
