In ASD diastolic murmur is mid diastolic

In ASD diastolic murmur is mid diastolic or delayed diastolic as in ur videos delayed is given and in medicine mid diastolic murmur is given ?

Atrial Septal Defect (ASD) is a congenital heart defect characterized by an abnormal opening or communication between the atria (upper chambers) of the heart. The type and timing of the murmur associated with ASD can vary, and both mid-diastolic and delayed diastolic murmurs can be observed depending on the specific characteristics of the defect.

  1. Mid-diastolic Murmur:
  • A mid-diastolic murmur is typically associated with the opening snap of the mitral valve and is commonly heard in mitral stenosis. It occurs in mid-late diastole and is associated with blood flowing from the left atrium to the left ventricle through a stenotic (narrowed) mitral valve. This murmur is not directly related to ASD.
  1. Delayed Diastolic Murmur:
  • A delayed diastolic murmur, sometimes referred to as a rumbling diastolic murmur, can be associated with ASD. It occurs in late diastole and is related to the increased flow of blood across the tricuspid valve due to the communication between the atria in ASD. This murmur is caused by the increased flow of blood from the left atrium to the right atrium through the ASD and then into the right ventricle.

In the context of ASD, the “delayed diastolic murmur” is more specific to the abnormal blood flow across the tricuspid valve, which is due to the left-to-right shunt caused by the ASD. The murmur occurs late in diastole as blood flows from the left atrium (higher pressure) to the right atrium (lower pressure) through the ASD.

It’s essential to differentiate between the different types of murmurs and their associated heart conditions. While mid-diastolic murmur is more related to mitral stenosis, delayed diastolic murmur is more indicative of ASD or other conditions involving abnormal flow between the atria. Always consult a healthcare professional for accurate diagnosis and interpretation of murmur sounds.
