Mitrial regurgitation (blood flowing backwards through the mitrial valve) with a sudden onset (starting suddenly). This would cause blood to be forced backwards through the left atrium and into the lungs at high pressure, which is bad. The high-pressure blood flow through the pulmonary circulation would cause pulmonary oedema (fluid buildup in the lungs, caused in this case by the liquid component of the blood being forced out of the capillaries into the alveoli), producing dyspnea (breathing difficulty). This in itself can be fatal, but if the patient survived this acute phase they would also experience chronic symptoms.

Over time, the left ventricle walls would hypertrophy (thicken and grow stronger in response to the increased load on them), which increases risks for arrhythmia. There would also be the development of dysfunction of the muscle, which would reduce pumping ability and exacerbate pulmonary congestion.

Mortality for acute mitrial prolapse is around 80%, so it's a bad thing to have. However, those who progress into the chronic phase tend to have a much better prognosis, with around 20% fatality rate over 5 years and 40% over 10. Pathologies associated with the chronic condition include increased risk of atrial fibrillation and endocarditis, with a small risk of sudden death.

In the under-20s, males are more frequently affected but over the age of 20 there's an even spread between men and women. Men over the age of 50 tend to suffer more complications, however. The mean age of occurrence is 36 +/- 6 years, and the condition is often secondary to heart attack

What would happen if the chordae tendineae were cut?

If the chordae tendineae were cut, the valves in the heart would not be able to close properly, leading to backflow of blood. This would result in decreased efficiency of the heart's pumping action and could lead to symptoms of heart failure. Surgery would be required to repair or replace the damaged chordae tendineae.


What might be the significance or nonfunctional or defective chordae tendineae?

The chordae tendineae keep the tricuspid and bicuspid valves from compressing past the point of closure when the ventricles contract. If the chordae tendineae were not functioning properly, the pressure from ventricular contraction would force the valve to open into the atrium and cause backward flow of blood. In summary, blood would flow the wrong direction, decreasing the heart's effectiveness.

What happens if the chordae tendineae is nonfunctional or defective?

the valve would fail to close or would invert when the heart contracts, this may cause heart failure.

What would happen if a tornado struck the prairies and lake region of Texas?

Pretty much the same thing that would happen if a tornado hit anywhere else., and that region, especially the northern part, is prone to tornadoes. Any trees in the tornado's path would likely be damage and possible uprooted or snapped and any man-made structures would also likely be damaged or destroyed. The severity of the damage will depend on the strength of the tornado.
