Dilated And Hypertrophic CMO Flashcards
Primary disease of the myocardium, excluding dysfunction due to ischemia or chronic valvular disease
Cardiomyopathy
Biatrial/biventricular dilation, ventricular systolic and diastolic dysfunction of LV +/- RV
Dilated CMO
Idiopathic, asymmetric hypertrophy of the heart
-hypertrophic, hyperdynamic and non-dilated LV
Hypertrophic CMO
- Increased resistance to ventricular filling due to lack of compliance
- heart failure with increased LVEDP, LAP
- Global systolic function may be preserved
Restrictive CMO
Disease of the myocardium characterized by the dilatation and decreased systolic function of the LV or both ventricles
Dilated CMO
Signs and symptoms of DCM
Related to CHF: low BP, fatigue, weakness, dyspnea/SOB
ECG in DCM
Large QRS (due to LVH)
What are the 2 most common types of regurgitation with DCM?
MR, TR
Abnormal M-mode finding of DCM?
B-bump due to high LVEDP
Increased EPSS
Disease of the myocardium characterized by the presence of LVH in the absence of another cause.
Hypertrophic CMO
Signs and symptoms of HCM
Decreased exercise tolerance, fainting, sudden death
ECG and auscultation findings in HCM
Arrhythmias and AV blocks, systolic murmur near Ao area
Which wall segment is most likely involved in hypertrophy that causes an outflow obstruction?
Basal anterior septum
What are the LVOT PG at rest in HCM vs HOCM?
HCM: <30mmHg, HOCM: >30mmHg
Two types of obstructions in HOCM?
Dynamic and latent
