URR Echocardiography
Transducer contains a large number of rectangular piezoelectric elements arranged in a linear pattern -
sector phased array



increasing the line density will _______ # of pulses per frame, improve spatial resolution (axial and
lateral), __________ frame rate and ___________ temporal resolution. increase/decrease? -
increases, decreases, decreases



a wave that requires a medium through which to travel, cannot travel in a vacuum - mechanical
wave



transducer that requires mechanical focusing and steering. electrical focusing and steering is not possible
- single element transducer



Multiple elements used to create an image by varying timing of the electrical pulses to different
elements in the array - phased array



high frequency probes have ________ penetration and _________ resolution - low, high



Combine sequenced linear array and phased array techniques to provide a trapezoidal imaging format -
vector array



In a sector image, the number of scan lines per degree of the sector determines ______ - line
density



increasing sector angle will have _________ spatial resolution and ________ temporal resolution.
degraded/improved? - improved, degraded



decreasing sector angle will _______ spatial resolution and ________ temporal resolution.
degrade/improve - degrade, improve

,list 2 types of spatial resolution - axial and lateral



Resolution with the ability to resolve two separate structures that lie parallel to the ultrasound beam -
axial resolution



forms aorta and pulmonary artery - trunctus arteriosus



forms left ventricle - primitive ventricle



Forms the atria - sino-atrium



forms right ventricle and truncus arteriosus - bulbous cordis



forms the atrial septum, membranous ventricular septum, MV and TV - endocardial cushions



composed of 2 segments that will become SVC, IVC and atrial floor - sinus venosus



connects pulmonary trunk to aortic arch, majority of flow bypasses fetal lungs - ductus arteriosus



connects the umbilical vein to the inferior vena cava, bypassing the liver - ductus venosus



position of apex - inferior, anterior and leftward



position of base - superior, posterior and rightward



which AV valve is closer to the apex? - TV

,normal valve area of TV - 5-8cm²



Which AV valve opens and closes first? - MV



which SL valve opens and closes first? - AoV



name leaflets of TV - anterior, posterior and septal/medial



name leaflets of MV - anterior and posterior



normal valve area of MV - 4-6cm²



which AoV leaflet lies closest to IAS? - NCC



normal AoV area - 3-4cm²



which coronary artery courses through the anterior interventricular groove? - left anterior
descending(LAD)



the right coronary artery (RCA) courses through the _________ __________ Groove - Right
Atrioventricular Coronary



the posterior descending coronary artery and middle coronary vein course through which groove? -
posterior interventricular groove



the left circumflex coronary artery (LCX) courses through the ________ __________ Groove - Left
Atrioventricular Coronary Groove



the right main coronary artery (RCA) supplies blood to which 5 structures? - both atria, atrial
septum, RVFW, and RV apex

, left main coronary artery (LCA) branches into what 2 arteries? - left anterior descending (LAD) and
left circumflex (LCX)



the LCX supplies which walls of the LV? - inferior lateral and anterior lateral



the LAD supplies what structures of the LV? - LV Apex, anterior septal wall and anterior wall of the
LV



the _____ papillary muscle is supplied by the RCA and the ______ papillary muscle is supplied by the
LAD and LCX - posterior medial, anterior lateral



the __________ collects deoxygenated blood from coronary arteries and has the lowest 02 sat of all
chamber and vessels - Coronary Sinus



list the 3 main tributaries of the Coronary sinus - Great Cardiac Vein, Middle Cardiac Vein and
Small Cardiac Vein



the _____ cardiac vein drains blood from the myocardium supplied by the RCA - small



the _____ cardiac vein drains blood from the myocardium supplied by the LAD and LCX - great



the _____ cardiac vein drains blood from the myocardium supplied by the posterior descending artery
(PDA) - middle



the PDA is a branch of the ______ ________ _______ and supplies the ________ and the ______ wall of
the LV - RCA, inferior ventricular septum, inferior



the epicardium is also known as the ________ _______ - visceral pericardium
