Why left ventricular
hypertrophy can be fatal if left untreated

If left ventricular  hypertrophy is left untreated, it may lead to diastolic dysfunction and decreased coronary flow reserve.

Explanation:

If left ventricular  hypertrophy is left untreated, it may lead to diastolic dysfunction and decreased coronary flow reserve. It increases the risk for atrial fibrillation, abnormal heart rhythm, systolic heart failure, diastolic heart failure. If left ventricular  hypertrophy is left untreated, it may also lead to sudden death in patients with hypertension.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
