• Genetic disorder of inappropriate LV/septal &/or RV hypertrophy

Answer 1

Hypertrophic Cardiomyopathy

Question 2

• MC cardiomyopathy
• HF symptoms; rales; tachycardia; cough, increased JVP
• Systolic dysfunction–>ventricular dilation–>dilated/weakened heart
• MC idiopathic
• TX: HF tx–>ACEI, diruetics, etc.

Answer 2

Dilated

Question 3

• Sx: R sided HF sxs, tachyarrythmias, increased JVP w/ inspiration
• Impaired diastolic dysfunction w/preserved contractility–> ventricular rigidity impedes filling
• Symptomatic tx
