CCI Review Echo 2-with 100% verified solutions-2023-2024 Right leaflet (the posterior leaflet is the non coronary) Which aor5c leaflet is the superior one in the parasternal long axis view? Pulmonary artery From the le> parasternal window which of the following are you most likely to get accurate velocity measurements? Anterior and medial/ septal Posterior can only be seen in RVIT plax In the parasternal short axis view (PSAX), which tricuspid leaflets are seen Some5mes in the parasternal SAX Aor5c Valve level (Typically seen in the apical 2ch) Normal LAA Velocity 46 cm/ sec? Where is the LAA on TTE? Sinuses of Valsalva The coronary arteries come off the? Early diastole During which phase do the coronaries fill? Right pulmonary artery What is the structure under the arch? Coarcta5on of the aorta (80%) NOTE: coarcta5on , MVP , and AO dissec5ons, bicuspid AOV are all related to Marfans Systolic click ejec5on= bicuspid AoV Mid Systolic click = MVP **TURNERS SYNDROME = MVP AND coarcta5on What cardiac pathology is associated with bicuspid aor5c valve? Right and le> superior (upper) pulmonary veins inferior to the LV NOTE: Can be seen on apical 4 chamber w/ inferior angula5on. Where are the pulmonary veins located? Right Atrium The chiari network is the Fenestrated por5on of the Eustachian valve it is located in the Right Atrium Where is the Chiari network (system) located? TTE: 2-7 MHz TEE: 5-7MHz What frequency is usually used for TTE and TEE? 40-50C or the highest temperature At what temperature is it unsafe to use a TEE probe? That period when a muscle cell is not excitable- from phase I un5l into phase 3 the "rela5ve refractory period" is during phase 3 and the muscle cell might contract if the s5mulus is strong. What is absolute refractory state? Includes P-R segment (from atrial to ventricular depolariza5on) What does the P-R interval represent? 0.10 sec. What is a normal dura5on for the QRS complex? Hyper-contrac5le (Regurgita5on increases preload, muscle tension/contrac5lity increases and eventually results in dilita5on, Volume overloads Acute Aor5c Insufficiency or Aor5c regurgita5on is _____ because we shi> up the Starling curve. Failure Chronic Aor5c Insufficiency or Aor5c regurgita5on is _____ when we drop off the end.
