Can you tell me the medical definition of hypertrophic obstructive cardiomyopathy?

Defined. Most often the portion of the heart between the right and left ventricles (septum) is thickened. This narrows the region below the aortic valve and causes a portion of mitral valve to be sucked into this area during ventricular ejection (emptying). As a result there is narrowing of outflow leading to obsruction.
Obstructing heart. Hypertrophic cardiomyopathy with obstruction is a condition of excess thickness of the left ventricle with overgrown muscle causing obstruction of blood flow out of the heart.

Usually fast work-up. The major test used to diagnose hypertrophic cardiomyopathy is an echocardiogram, a painless outpatient test that takes no more than an hour. Sometimes this is combined with exercise, extending time to two hours. Rarely, esp if invasive therapy is being considered, you may need a catheterization, which takes a full day and often an overnight stay.
Yes, lifelong. Lifelong follow-up is required. It is a condition in which the heart muscle is thick, and obstruction to outflow may occur. Arrhythmias may occur as well.
