Obstruction of circulation through the lungs can put a strain on right ventricle which must work to pump blood against this increased resistance and lead failure that chamber?

True.

Obstruction of circulation through the lungs, as in pulmonary stenosis or pulmonary embolism, can lead to pulmonary hypertension. This can put a strain on the right ventricle, which must work harder to pump blood against the increased resistance in the pulmonary circulation. This can lead to right ventricular hypertrophy and eventually right ventricular failure.
