Q. What are the coronary arteries in echocardiography?
Doctor Answer is medically reviewed by SecondMedic medical review team.
In echocardiography, coronary arteries are the main vessels that supply blood to the heart. These are three major arteries: the left main coronary artery (LMCA), the left anterior descending artery (LAD) and the circumflex artery (CX). The LMCA originates from the aorta and splits at its bifurcation into two branches, namely LAD and CX.
The LAD is also known as "the widow-maker" due to its narrow anatomy. It supplies oxygenated blood to part of the front of heart muscle including septal walls and anterior walls of both ventricles. On echocardiography, this vessel is visualized on a transverse plane like a thin dividing line between ventricular chambers in parasternal long axis view or in apical views with certain colors depending on velocity of flow within it; blue/green is normal flow while red indicates stenosis which could be indicative of coronary artery disease if seen acutely with chest pain suggestive symptoms too.
The other branch of LMCA - CX - runs around the circumference or obliquely towards right atrial appendage supplying posterior surface lateral wall & inferior wall portions along with parts of apex region laterally & superiorly. Its visualization may vary depending on imaging equipment used but mostly it appears not so clearly compared to LAD so special technique like harmonic imaging can be employed for better clarity as well as identification in some cases where acute changes occur in stenotic condition specially when assessed for further management options such as stenting by interventional cardiologists afterwards.

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
