A. Branches of Left coronary artery:

"CX-LAD"

Read as "6 Lads!"

  • Circumflex artery (CX)
  • Left Anterior Descending Artery (LAD)

B. Posterior descending artery:

"Post desc-PIG-IIS"

Read as "Post desk Piggies!"

  • Posterior descending artery runs through PIGs (Posterior interventricular groove) & supplies the IIS (Inferior part of Interventricular Septum).

 "A.B.C'S"

Arch of Aorta gives rise to

  • Brachiocephalic trunk
  • Common carotid artery (left)
  • Subclavian artery (left)

Occasionally thyroidea ima and vertebral aretry may arise from it.

 

 

 

Arch of Aorta begins at the upper border of second sternochondral joint on the right and ends at the fourth thoracic vertebra by becoming the thoracic aorta. Thus is begins and ends at the the same horizontal plane although it begins anteriorly and ends posteriorly.
Thoracic aorta is auscultated at the back of chest i.e., dorsal aspect of the upper trunk.

Restrictive cardiomyopathy results from pathologic infiltration of myocardium by variuos disease processes.

 'MEGACHRIST'

  • Metastasis
  • EMF
  • Glycogen storage disorders
  • Amyloidosis
  • Carcinoid
  • Haemochromatosis, Hypereosinophilic syndrome
  • Radiation
  • Idiopathic
  • Sarcoidosis
  • Transplant
It is often difficult to differentiate between restrictive cardiomyopathy and constrictive pericarditis but this distinction is critical as surgical treatment may be effective in constrictive pericarditis
In restrictive cardiomyopathy ECG may show conduction disturbance or low voltage complexes
Restrictive cardiomyopathy results in abnormal diastolic ventricular filling and varying degrees of systolic dysfunction
