TAD Awareness September 2020 - More Awareness, Many Challenges Today

On this last day of September 2020, where are we in terms of awareness of aortic disease in the chest, both for the public and for medical professionals? 

Are We Still Learning "the Hard Way"?

Once the aorta threatens or takes away someone's life there is painful "awareness". It is a "hard way" to learn about a potentially deadly condition. For physicians, missed or delayed diagnoses and possibly loss of a patient are also learning "the hard way"; that is, if the diseased aorta is actually ever discovered at all. It is possible, in the absence of autopsies, that deaths due to aortic disease in the chest remain hidden, uncounted.

Would it Be Different Today?

At the time Michael Kirk went to the ER with symptoms, he was a cardiac intensive care nurse at that very hospital.  No one thought of his aorta, although over an agonizing 68 hours, they thought of many other things, including anxiety! The medical team ultimately learned from Michael, and he survived the crisis.  Michael shared his experience with BAF here. Thinking of Michael's experience, would it be better in 2020? Would his family members, assumed to have died suddenly of "heart disease" be checked for aortic disease today?

In 2020, Someone Still Needs to Think of the Aorta in the ER

There is a marker in the blood, troponin, that indicates heart muscle injury (typically signs of a heart attack) that appears to be broadly understood and used. There is no simple equivalent for the aorta today. Currently, someone needs to think of the aorta, to rule it in or out with imaging, as one of the major killers in the chest.

 However, a paper published in July 2020 offers hope for additional diagnostic help in the future. Imaging and Biomarkers in Acute Aortic Syndromes: Diagnostic and Prognostic Implications :  "It is expected, in the near future, the development of serologic and imaging biomarkers able to early detect clinically-silent pathologic changes in the aorta wall before (primary prevention) and after (secondary prevention) the acute index event."

This is hopeful news! However, checking for these biomarkers would still require that someone thinks of the aorta, not just the heart!

This court case is an example of death after being sent home from the ER, when the aorta was not considered. 

Richard Houchin, whose aorta dissected in 2004,  remembers hearing someone say "aorta" while in the ER, and thinking fuzzily, what is my aorta? Richard had a number of things "go right" that day, beginning with the paramedics who thought of his aorta, despite instructions from a major medical center to treat him as a heart attack victim.

When it is not a heart attack, we can help physicians think of the aorta in the chest by bringing it up to them.

In 2020, Someone Needs to Care for Aortic Dissections Survivors

An article published this September has this poignant title: 

Am I going to die now? Experiences of hospitalisation and subsequent life after being diagnosed with aortic dissection

The full article is not freely available to the public. However, as the abstract indicates, this is an effort to understand and improve the experience of those who survive aortic dissection. 

In 2020, Someone Needs Answers and Support When Thoracic Aortic Disease Causes Sudden Death

There are no words to describe the devastation left behind among the living who suddenly lose a loved one. 

How many times is aortic disease in the chest the actual culprit, not a "heart attack"? 

Amy's family had the courage and resources to arrange for a private autopsy, which unmasked the undiagnosed BAV and diseased aorta that abruptly took her life. Here is Amy's story.

In 2020, Focus is Still Needed on the Aorta, Not Just the Heart

For those with BAV, they may only be told about their aortic valve and heart. I recently spoke to the mother of a wonderful, active boy, age 14. While hospitalized at a major medical center for another reason, the presence of a bicuspid aortic valve was discovered. The initial information given was not overly concerning. When following up with a local cardiologist later, however, this boy and his parents were shocked to be told that his aorta was enlarged, and his physical activity should be limited. 

How could that be possible? His aorta had not even been mentioned, and all of a sudden, it is an issue important enough to restrict his sports participation? This is devastating to anyone, let alone an active, strong teenager.

It was not easy in my own family when a large ascending aortic aneurysm was "discovered", years after being told all was safely fixed following BAV replacement surgery. Later we learned the aorta was already enlarged at the time of the BAV replacement and had quietly continued to grow! 

No, it is not easy to work through the emotions and lifestyle changes that may follow abruptly learning about an enlarged/aneurysmal aorta. Acceptance of physical restrictions and lifechanging adjustments are not trivial for those whose bodies are seemingly so healthy, often naturally gifted athletes who are typically involved in numerous activities and sports. 

Parents, families, and each one with BAV deserve compassionately shared accurate information about their aorta along with their BAV/heart, ultimately enabling them to live with confidence, supported by their medical care team.

The following paper published in 2020 provides international information from multiple medical centers, regarding 2,122 BAV children; half of them had an enlarged aorta. Their average age was 10.2 years.

Keeping Our Focus on the Aorta Every Day, Every Month, All Year Long

At BAF we have been observing September TAD Awareness for a number of years. We find in 2020 that the aorta in the chest still presents many challenges. The various efforts to raise awareness this year all help the public understand the importance of their aorta, this large candy-cane shaped artery that begins with their heart. May we maintain this focus every day, every month, all year long. 

 On this last day of September,
 we can help everyone we meet
to remember the aorta and
seek accurate information,
empowering them to live confidently,

September Awareness 2020 - Aortic Follow Up Tests Amid COVID-19 Pandemic

No photo description available.

No matter where we are in our aortic journey, checking on aortic status (aorta, aortic valve, heart overall) inside the chest is part of life, as long as we live. It is so fundamental that it is the "A" in the Bicuspid Aortic Foundation's "Aortic ABC's"

Imaging tests such as echocardiogram, CT, and MRI, provide a great deal of information about aortic disease. Providing amazing detail, state-of-the-art CTA tests provide vital information, including aortic valve leaflet function in the beating heart. 

Serious, life-threatening issues with the aorta in the chest may be silent, nothing wrong is "felt". Imaging studies to check the aorta (and heart) are important in order to prevent potential injury and loss of life.

Following is an account of the tragic loss of a young man whose aortic CT scan was not done in early June as planned, due to a COVID-19 lockdown at the hospital. He collapsed while jogging on August 13th and died August 15th. The CT scan intended to check the status of his aortic stent was never done.  Reading about the damage inside his body that ultimately took his life is indescribably shocking, horrifying. He was only 19 years old.

Corbella: Prairie teen killed by lockdown, not COVID-19


Between a Rock and a Hard Place in 2020
COVID-19 complicated decisions around imaging in my own family this year. Initially all went so well, when someone traveled out of state to receive a TAVR valve along with a stent to protect blood flow to the heart. Yes, highly skilled hands saved a life, just before most medical facilities "locked down". But plans for follow up imaging, both echo and CT, were deferred. And then, when an echocardiogram was available locally, it showed an alarming increase in pressure across the new TAVR valve.

What could possibly be wrong? 
One possibility was a complication called leaflet thrombosis that sometimes happens with biological valves. Blood clot formation, including the potential to block the stent which would be deadly, needed to be ruled in or out. It would take a specialized CTA scan to understand what was happening, only available by out-of-state travel.

Weighing the Risks - the Virus or the Heart?
Sometimes the decisions that must be made can be almost overwhelming. The specialized CT protocol was shared with local medical cardiac professionals, but they could not provide it there. The choice was: risk COVID exposure, including air travel, or risk the new valve and stent. Either one was potentially deadly. Ultimately, the decision to travel was made, taking all possible precautions. 

What happened?
The specialty CTA scan revealed that the TAVR valve and stent were fine, no blood clots! It was explained that sometimes, in a case like this, the echocardiogram is not able to accurately calculate the pressure difference across the aortic valve. Yes, sometimes it is complicated. 

It was good news, but risk was taken to get it. Thankfully, the travelers did not contract COVID-19. This is the reality of dealing with aortic disease in the chest - the aorta and the heart - in 2020. Aortic disease is challenging for many reasons, and the unknowns of COVID-19 have added to those challenges, as it has for other conditions. I have had conversations with others who struggle with going for follow up echocardiograms and cardiology visits. To date, they have done so safely, as hospitals and physicians develop sanitation protocols to protect everyone. There is a renewed emphasis on infection prevention, which is a good thing, for both viral and bacterial infection prevention.

As you and your doctors
follow your aorta and your heart,
in 2020 and the years to come,
you are

Thoracic Aortic Disease Awareness September 2020 - TAD in the Midst of COVID-19

 How many have been injured or died from a diseased aorta in the chest (thoracic aortic disease (TAD)), not receiving treatment for various reasons during the COVID-19 pandemic?

Did the pandemic come between those with a torn aorta in the chest and the emergency physicians and skilled surgeons who could save them? It is reasonable to believe it did. The following is written by physicians in New York:

In the above, a "significant and precipitous drop" was identified in the number of surgeries for acute aortic dissection. The best hope for someone with acute type A dissection, which involves the ascending aorta and strikes without warning, is coming to the ER, being diagnosed, and receiving emergency surgery. How many were denied that opportunity due to the pandemic?

As the above concludes:

"It is critical, as we adjust to the pandemic, to balance the public health imperative of social distancing with the individual need to consult in the presence of sudden severe symptoms. Furthermore, additional resources, ranging from telemedicine to numbers of first responders, should be greatly increased. This serves as a word of caution for cities yet to experience a surge in COVID-19 cases, as well as for future similar events."

Inspiration and Also A Warning

The following is an account of a professor from Idaho who traveled to New York for life-saving complex aortic surgery during the pandemic. It is hopeful and inspiring, while at the same time containing a warning about the vital importance of lifelong monitoring of the aorta in those born with bicuspid aortic valves.

BACK IN BUSINESS: CEED Director undergoes life-saving heart surgery in New York amid pandemic

One of the surgeons who saved Jeff Street, pictured with him in the article, is Dr. El-Hamamsy, who is also among the authors in the first article above. He is among the skilled surgeons that could have helped those living nearby also, if only they had reached him.

Regarding the warning in this man's experience, it is important to avoid unnecessary, life-threatening aortic dissection or rupture in the first place. How did this man's aorta reach this very fragile state undetected? 

Jeff Street had surgery to address his bicuspid aortic valve 23 years earlier. Presumably he had cardiac care over those years, but what about his aorta?

Only when he became symptomatic this year, the article states, was an aneurysm "discovered". More concerning still, was the actual condition of his aorta when fully exposed during surgery on June 9th (quoting from the article):

“Absolutely it was a life-saving surgery,” Street said. “I did not know that my aorta already had a small leak on it. The only thing holding it together was the scar tissue from my previous surgery 23 years ago.”"

Words like "miracle" come to mind as one reads about this man's experience - fragile tissue somehow holding together until he was in the hands of a surgeon with the skills to save his life.

And then, thoughts turn to those whose lives have ended abruptly, unknown and uncounted.

For those in BAV families, aortic valves are unquestionably important and vital. It would be beyond a tragedy to provide state-of-the-art treatment and care for their aortic valves, but not their aortas. 

This September 2020, once again it is important to raise awareness of the aorta in the chest in those born with bicuspid aortic valves and their family members.

In the midst of  this pandemic,

We again highlight the aorta in the chest,
