Tricuspid Regurgitation pathophysiology, investigation and treatment

Join this channel to get access to perks:

"Tricuspid regurgitation is characterized by the backflow of blood into the right atrium during systole.

The Tricuspid valve is an atrioventricular valve preventing blood from flowing from the right ventricle to right atrium. The other atrioventricular valve is the mitral valve. Anatomically, the tricuspid valve consists of anterior, septal, and posterior leaflets.

Tricuspid regurgitation is characterized by the backflow of blood into the right atrium during systole. Tricuspid regurgitation may be Primary or Secondary (most common). Secondary tricuspid regurg is functional and is due to dilatation of the right atrium and RV with dilation of the tricuspid annulus. These changes are often caused by pulmonary hypertension."

Legend, a living legend you are.
Bless ya soul for providing all of us with free medical content for a lengthy & consistently period of time.

I agree the animation is superb especially the dilation of the tricuspid annulus to really bring it home what is happening in secondary tricuspid regurgitation. Thanks and well done.

[thomasmccann]

Could you please make more heart valve disease videos in this format- it really is effective!!! 👌

[MelomaniacEarth]

Your handy animation is far more better and understandable.

بسیار روان و شیرین ارائه شد .
Very clear, succinct and helpful in the same time 💐💐
Thanks

I was initially confused how the contracting of papillary muscles would cause the closing of the tricuspid valve via the tension physics of the chordae tendinae since usually contracting is synonymous with shortening not elongating. However your illustration @ 01:34 makes me realize that the contraction of the papillary muscles are actually contracting the cardiac muscles and minimizing the volume in the right ventricle chamber, and a byproduct is the plunging of the tricuspid valves closed toward the right atrium. This clears up my understanding of physiology!

Very nice explanation. Please make a video on tricuspid stenosis 🌹💟🍦

Woow it is more interesting, I love ur Australian accent

They are not V waves. The v wave is part of normal valvular behavior and occurs at a different time of the cardiac cycle to the giant systolic venous waves of TR

Sir, i am B negative & husband is B positive, 1st miscarriage me anti D nahi lga tha, second pregnancy me 5 month baby kharab hua tha to normal delivery krni pdi or mujhe anti D diya gya, ab mujhe DCDA twins baby consive huye but NT scan me pta chala ki ek baby ki heart beat 8 week pr band ho chuki h or ek baby healthy but usme bhi tricuspid regurgitation absent btaya he to mam kya ye problem anomaly scan tk thik ho jayegi ya phir ye baby bhi mujhe nikalna pdega ..😣😑 Plz reply me apne baby ko khona nahi chahti plz suggests kre
