How does chronic aortic stenosis lead to left ventricular hypertrophy? Chronic aortic stenosis leads to left ventricular hypertrophy bc of increased workload of pumping blood through a narrow opening. The left atrium can also enlarge but mainly causes left ventricular hypertrophy. The right ventricle will remain normal for a period of time. That's why LHF happens first then leads to RHF. Chronic mitral stenosis will cause enlargement in which area? Left atria hypertrophy. In pt with Mitral v...
