Questions: Aortic valvular stenosis will cause increased work for the left and eventually will lead to Answers are in the form of "first blank, second blank". atria, ventricular hypertrophy atria, atrial atrophy ventricles, atrial atrophy ventricles, ventricular hypertrophy

The answer is the last one: ventricles, ventricular hypertrophy.

Explanation for each option:

1. Atria, ventricular hypertrophy: This is incorrect because aortic valvular stenosis primarily affects the left ventricle, not the atria. The increased workload is on the ventricles, leading to ventricular hypertrophy.

2. Atria, atrial atrophy: This is incorrect because aortic valvular stenosis does not directly cause atrial atrophy. The condition affects the left ventricle, leading to increased workload and hypertrophy of the ventricle.

3. Ventricles, atrial atrophy: This is incorrect because while the ventricles are indeed affected, the result is not atrial atrophy. The increased workload on the ventricles leads to ventricular hypertrophy.

4. Ventricles, ventricular hypertrophy: This is correct. Aortic valvular stenosis causes increased resistance to blood flow from the left ventricle, leading to increased workload on the ventricles. Over time, this results in ventricular hypertrophy as the heart muscle thickens to compensate for the increased workload.

In summary, aortic valvular stenosis increases the workload on the left ventricles, eventually leading to ventricular hypertrophy.
