A young, apparently healthy athlete, while playing collapses to the ground and dies.. Diagnosis?
Hypertrophic obstructive cardiomyopathy.
Right, as always!
Will probably also have family history!
Oh oh review question - what is the site of obstruction in HOCM?
Ventricular septal wall?
Left ventricular outflow is obstructed.
Yup. Basically below the outflow tract of the aorta.
What will happen to the intensity of the murmur in HOCM during Valsalva maneuver?
It will increase. HOCM and MVP are the only two conditions in which a decrease in blood volume to the heart increases the intensity of the murmur.
What's Brugada syndrome??
In Brugada syndrome there's risk of sudden cardiac death.. And it's also genetic..
Oh.. Didn't know. What is the defect in brugada syndrome? In HOCM it is beta myosin I guess.
Some defect in sodium or calcium channels I guess.. Not sure.
Ohh okay. Thanks!
