A brief introduction to the pathophysiology of cardiac tamponade as an oncologic emergency, including a discussion of Beck's triad and pulsus paradoxus.
Thank you soo much Andrew! I was confused about pulsus paradoxus and have been looking everywhere on UA-cam to get a better understanding wheeew! Your video answered my questions. Many2x thanks. God bless u
Andrew, yer' killing it! Your videos are awesome! Your lectures are comprehensible and your animations make the pathophysiology of your subjects easy to understand. I'm an aspiring paramedic and I've recommended your work to many of my fellow students. Whenever I'm bombarded and confused by the medical jargon, I turn to your videos to make sense of it all! Thank you sooo much. Wish I had you for a teacher!
Andrew, Thanks for an excellent video, I have few questions for you, when you have time - Reason for my question is my mom passed away few days back and preliminary autopsy report says - -cardiac tamponade(550 ml blood) due to thoracic aortic dissection -14 cm aortic dissertation , heart weight 350gm 1. What might trigger this situation ? In other words what would cause the fluid/blood to move between Parietal and visceral pericardium ? A. Can hypertension/ high HDL / LDL be the catalyst ? B. Cold temperature can effect (about 50-55 Fahrenheit )? C. Any past accident or if someone punched on the chest very hard might be the culprit ? D. I don't think Tamponade can kill someone in very short time, how much time it may take from the time Tamponade started to the time when the person may die.(or around 550 ml blood can accumulate in the sac) E. It may cause sudden death without any chest/back pain or other symptoms in past ? if not, at-least what symptom should occur (other then hearing pain in chest, that killed the person)? F. Extra pressure while on toilet/motion(with constipation) can trigger it ? G: Cardiac Tamponade may happen due to the initial life saving steps performed by the emergency/ambulance team? and actual reason might be something else for the death? 2. Is there any relation between Cardiac Tamponade and paralysis or arthritis (wondering if its in the gene)? Any pointers would be much appreciated.
+James Jones I think a low Albumin level could contribute to the retention of fluid in the limbs, which could result in ventricular heart failure rather than a cardiac tamponade. This is something I am still very much getting my head round so don't quote me on it.
Great presentation. However, a critical feature of CT was not discussed is that how diastolic pressures of the 4 chambers equilibrate to 15-20 mmHg. I've been looking for a good explanation and just can't find one. Is it that the intra-pericardial pressure compressing the heart is compensated for by changing the internal anatomy (septum deviation) to equilibrate the interior pressures (e.g. one chamber with 20 mmHg pressure and another with 40 mmmHg will adjust to both have 30 mmHg)? Or is it that once the pressure compresses the heart enough, the volume within each chamber is the same and can only take a maximum volume (that is the same for all chambers), thus leading to the same diastolic volume? If you know the mechanism, please write a comment. I'd really appreciate it!
Been a couple years but maybe this will help someone else with the same question: The pressure within the pericardial space due to the fluid accumulation is 15-20mmHg in this scenario. Therefore when the atria/ventricles attempt to relax, they are limited by this pressure. Thus, a normal RA attempting to reach its resting 5mmHg, will be limited by the pericardial pressure of 20 mmHg. The pericardial pressure is the same throughout the heart thus equalization of diastolic pressures.
i have a question, someone suffers a cardiac tamponade but has never had open heart surgery or any other surgery for that matter. what could be the cause of this?
Thank you very much for providing a good understanding of cardiac tamponade
Glad it was helpful! Thanks so much for watching!

Andrew,

1. What might trigger this situation ? In other words what would cause the fluid/blood to move between Parietal and visceral pericardium ?

Wonderful videos and very helpful
Glad it was helpful! Appreciate the feedback!
Great video!! Am I incorrect or is that the Superior Vena Cava that you labeled IVC? Or is it something different?
thank you,,,,,,,,,,,,,,,,that was helpful
Glad it was helpful! Thanks for watching
Thank you so much for your videos, however I don't see Oncologic Emergencies hypercalcemia uploaded.
You're welcome Estraica, we will be rolling out new lessons soon. Keep watching, we appreciate the support!
Do all 3 of Beck’s Traid need to be present at once for it to be tamponade? What if just one is present?
Would a low albumin level contribute to this accumulation of fluid? Thanks.
+James Jones I think a low Albumin level could contribute to the retention of fluid in the limbs, which could result in ventricular heart failure rather than a cardiac tamponade. This is something I am still very much getting my head round so don't quote me on it.
Thanks for the question. We will ask Dr. Wolf and see what he says!
Thank you ...u helped alot
Glad it helped

Appreciate the input Garrett!
Thanks for the question! We have passed it along to the Health Ed Solutions medical review board.
i have a question, someone suffers a cardiac tamponade but has never had open heart surgery or any other surgery for that matter. what could be the cause of this?
Wambui Karanja cardiac temponade can be caused by chest trauma, ascending aorta dissection, and surgery..also it can happen due to malignancy
Good question. We will check with Dr. Wolf and see what his input is. Thanks for watching!
thank you
Money!!! thanks!!!
Thank you for watching and glad it was helpful!
Great lecture. Thank you!
