Tricuspid valve regurgitation.

Tricuspid regurgitation (TR) is often an incidental finding on routine echocardiography. While a mild degree is generally regarded as a benign physiological entity, moderate and severe TR are associated with worse outcome.

Tricuspid valve regurgitation is a condition in which the valve between the two right heart chambers (right ventricle and right atrium) doesn't close properly. The malfunctioning valve allows blood to flow back into your heart's upper right chamber (right atrium).

Tricuspid valve regurgitation can be the result of a condition you're born with (congenital heart disease), or it can occur due to valve abnormalities caused by other conditions.

Tricuspid valve regurgitation is usually caused by the lower right heart chamber (right ventricle) increasing in size, which can cause the tricuspid valve to stop working properly. Several conditions that affect the right ventricle, such as heart failure; conditions that cause high blood pressure in the arteries in your lungs (pulmonary hypertension); or an abnormal heart muscle condition (cardiomyopathy) also may cause the tricuspid valve to stop working properly.

Cardiac Ultrasound findings

Parasternal short axis: trace pericardial effusion, left ventricular function and wall thickness grossly normal. Interventricular septum flattened, with septal bowing toward left ventricle in both systole and diastole. Right ventricle dilated.

Apical 4 chamber: color flow Doppler across tricuspid valve demonstrates aliasing, a large flow convergence zone, and a large tricuspid regurgitant jet into a dilated right atrium. Right ventricle is dilated with decreased function.

Signs of right ventricular pressure and/or volume overload may increase suspicion of pathologic regurgitation, including flattening of the interventricular septum, right ventricular dilation, and right atrial dilation with leftward displacement of the interatrial septum

Valve stenosis (“narrowing”) is a disorder characterised by stiffening of the heart valve flaps. It can occur as a congenital defect, a consequence of prolonged calcium ion imbalance, or an infection. Patients experiencing valve stenosis often have obstructed blood flow that requires surgical intervention. Think about how the blood flow would be disrupted as it passes each of the heart valves if they were stiff. What happens to the heart over all?

Design an electro-pneumatic circuit to control a double-acting cylinder via a 5/2 way singlesolenoid valve. The on switch is of detent type and when actuated, the piston will repeatedly extend and retract until the switch is released. The length of forward stroke and the speed of forward and return motion should be adjustable via roller-limit switches and flow control valves respectively. (a) Show pneumatic and electrical circuits for indirect control of the system described above, i.e. each switch in the...
