Clinically Relevant Anatomy of the Heart Flashcards
Haemopericardium
Pericardial cavity fills with blood
Cardiac Tamponade
compression of the heart by an accumulation of fluid in the pericardial sac
Pericardialcentesis
drainage of fluid for the pericardial cavity
Pericardialcentesis procedure
insert needle via intrasternal angle superoposteriorly
Sinus
sac or cavity in any organ or tissue
Transverse pericardial sinus
space within the pericardial cavity
lies posterior to the ascending aorta and pulmonary trunk
(cardiac surgeons use this to identify the great vessels)
Apex beat
5th intercostal space, mid clavicular line
Cardiomegaly
abnormal enlargement of the heart
Coronary Groove (right coronary artery)
indicates the surface marking for the tricuspid valve
Tricuspid valve
between the right atrium and the right ventricle
Anterior interventricular groove (branch of left coronary artery)
indicates the boundary between the two ventricles
Posterior inter ventricular groove ( branch of the right coronary artery)
indicates the boundary between the two ventricles on the diaphragmatic surface of the heart
Coronary Sinus
“collection of veins”
short venous conduit which receives deoxygenated blood from the cardiac veins and drains into the right atrium
Two parts to the septum
- inter arterial groove
2. inter ventricular groove
Atrial Septal Defect
hole in the interarterial septum
Ventricular Septal Defect
hole in the inter ventricular septum
Tricuspid valve
anterior, posterior and septal cusps
Mitral valve
anterior and posterior cusps
Pulmonary valve
anterior right and left cusps
Aortic valve
right, left and posterior cusps and sinuses (spaces within cusps)
Aortic Area
2nd right ICS sternal edge
Pulmonary Area
2nd left ICS sternal edge
Tricuspid Area
Between the 5th and 6th ICS sternal edge, lower left sternal angle
Mitral Area
6th left ICS midclavicular line
ICS
intercostal space
