Waveform
What is semilunar valve closure
This type of Heart Failure occurs when the heart's ejection fraction remains normal, but the ventricle has impaired filling
What is Heart Failure with Preserved Ejection Fraction (HFpEF)
An RA sat of 38% most likely drawn from?
What is the coronary sinus
Most common valvular lesion, LV systolic increases while aortic systolic decreases
What is aortic stenosis
This device augments coronary perfusion during diastole and decreases afterload during systole
What is an Intra-Aortic Balloon Pump
The LVEDP occurs just after ____
What is the A wave
What conditions limit the accuracy of thermodilution?
What is tricuspid regurgitation, intracardiac shunting, arrhythmias.
How many total claves are needed for a leave in swan?
5
Absence of x descent and large c-v wave with prominent y descent is indicative of
What is Tricuspid Regurgitation
This device sits across the aortic valve and pumps blood from the left ventricle to the aorta
What is an Impella CP
During engagement of an ostial left main lesion, the pressure waveform becomes severely ventricularized with loss of the aortic dicrotic notch. This occurs because the catheter is occlusive and is now primarily reflecting this phase of the cardiac cycle.
What is end-diastolic pressure
RHC numbers of RA 18, PA 25/10, PCW 8, CI 2.8 indicates
What is RV failure
When doing a study for Mitral Stenosis what pressures are we looking at?
What is the LA (PCW) and LV pressure
Increased RV systolic, pressure overload, RV hypertrophy indicates
What is Pulmonic Stenosis
In patients with acute RV infarction, RP impella support improves systemic perfusion primarily by increasing flow through this cardiac chamber
What is the left ventricle
RV pressure takes a square root morphology during diastole paired with a rapid y descent in the RA waveform
What is pericardial constriction
Based off these RHC results: RA 3/5 (4), RV 50/2/5, PA 52/12 (25), PCW 11/12 (11) CO:3.97, PVR: 3.53 wood units, what would we diagnose this patient with?
What is precapillary pulmonary hypertension
A decreased cardiac output, accentuated a wave, prominent v wave and delayed y descent are indicative of
This hemodynamic index, calculated from RHC measurements is commonly used to identify patients with significant RV dysfuntion who may benefit from right sided mechanical support
What is the Pulmonary Artery Pulsatility Index
Discordance in the RV and LV diastolic pressures of more than 5mmhg with inspiration indicate
What is Restrictive Cardiomyopathy
RHC numbers PA 20, RV 60/20, PA 60/30, PCW 20, CI 1.2 indicates
What is cardiogenic shock
Assumed O2 consumption/(A-VO2 difference x O2 capacity) x 10
What is the Fick Cardiac Output calculation
Rapid upstroke in LV pressure obscuring a wave and culminating elevating EDP with a decreased cardiac output indicate
Acute aortic regurgitation
A patient is in profound cardiogenic shock following an AMI. Despite multiple pressors and an Impella, they remain severely hypoxic and are in severe biventricular failure. What is the next step in escalation?
What is VA-ECMO
