12 COVID-19 Double-Lung TransplantsPublished March 2021 They hadn't thought much about death because they were otherwise healthy. Suddenly, dying was a possibility. Then, they woke up, weeks or months later, with a new set of lungs. This is the story of 12 near-death experiences and 12 lives saved by a first-of-its-kind procedure: a double-lung transplant for people who had survived severe COVID-19 but had irreparable lung damage. "The COVID-19 double-lung transplant gives patients who were unprepared for death — and suddenly facing it — the opportunity to come back to life," says Northwestern Medicine Pulmonary Thoracic Surgeon Ankit Bharat, MD, who pioneered the procedure. "Without it, these patients may have never woken up after being put on ventilators because of how badly COVID-19 damaged their lungs."
Paths of AttackWhen SARS-CoV-2, the virus that causes COVID-19, enters your system, it can latch onto the cells that line your respiratory tract. This includes your windpipe and your lungs. Then, it starts to multiply, at the expense of your healthy cells. Sensing danger, your immune system fights back, resulting in such common symptoms as a cough and fever. "Your immune cells come together to fight COVID-19, which creates inflammation, like a small wildfire," explains Dr. Bharat. "Depending on many factors, this wildfire can grow, causing massive inflammation and damage." In the case of the 12 people who had double-lung transplants at Northwestern Memorial Hospital after having COVID-19, their immune systems could not put out the wildfire. SARS-CoV-2 spread through their respiratory systems, damaging their lungs.
Those patients required the most advanced treatment possible in the Intensive Care Unit (ICU). They were placed on ventilators or received extracorporeal membrane oxygenation (ECMO) from a machine that put oxygen into their blood with an external artificial lung.
When a patient with COVID-19 is on a ventilator or ECMO machine, the hope is that their infection will clear, their inflammation will go away and their lungs will start to heal themselves so they can breathe on their own. But, healing did not happen for these 12 patients. They beat the virus, but their fight to survive was not over. The damage caused by COVID-19 took two main forms.
Inflammation and Infection
Inflammation can cause more inflammation. In patients with COVID-19, immune cells in the lungs can become too weak to fight off any intruder. That means other infections can easily take hold. If a bacterial infection occurs, the lungs become so weak that they cannot fight off infection, even with the help of the strongest antibiotics. The bacterial infection can spread into the bloodstream, causing sepsis and organ failure.
In July 2020, Chicago resident Mayra Ramirez became the first known person in the United States to receive a double-lung transplant after COVID-19 destroyed her lungs.
Mayra's lungs could not fight any infections. Pus clogged them, preventing her from being able to breathe. When Mayra was in a medically induced coma on a ventilator, she says all she remembers are dreams where she felt like she was drowning. During this time, her lungs were becoming "mushy with infection," according to Dr. Bharat.
Inflammation and Scarring
Some patients can outlast their COVID-19 infection and begin to heal. But, healing can involve creating scar tissue, and stiff scar tissue is not ideal in the lungs. Lungs need to be soft, with tiny holes that allow the transfer of oxygen into the bloodstream.
Roberto Rodriguez, the eighth person to receive a double-lung transplant following COVID-19, spent 130 days on ECMO. This is the longest any patient is known to have spent on the machine. His lungs became tough.
Scarring or infection can happen within the first few weeks of COVID-19 infection, or even a few months into the illness.

Breakthrough in COVID-19 Care
A double-lung transplant was the only remaining treatment option for the 12 people at Northwestern Medicine who had one.
"For Mayra, the first transplant recipient, she was young and otherwise healthy, with no options. I wanted to do everything I could for her," says Dr. Bharat. "There were a lot of challenges and tough decisions, but we knew this surgery was the right thing to do."
Mayra's surgery lasted 10 hours.
"They were 10 hours of uncertainty,” says Dr. Bharat. “Managing that uncertainty and all the unexpected turns throughout the procedure required being as efficient and focused as a team as possible."
From a medical standpoint, this procedure establishes for the first time that organ transplants can be effective after organ failure from infectious causes. Typically, organ transplant is considered because an organ is damaged by a chronic condition, such as emphysema, kidney failure and heart failure.
"Because this was a nontraditional use for organ transplant, we didn't know at first if the virus was going to come back after transplant," says Dr. Bharat. "Now we know that transplant is a viable option for damage from infection, and we are considering transplant for other infectious diseases like influenza."
Dr. Bharat has seen 100% success in the outcomes of all 12 patients who had transplants. The road to recovery is slow. But because their disease was caused by a temporary infection, recovery is faster than for patients who need transplants for chronic lung conditions like cystic fibrosis or pulmonary fibrosis.
"Patients near death are getting back to living their normal lives," says Dr. Bharat.

Leading the Quest for Better Medicine
Research on how viruses impact the body is usually done in laboratories over the course of years. With COVID-19, physician-scientists simply didn't have the time. They had to learn about how COVID-19 attacks the lungs while caring for patients with the virus in the ICU.
Investigators worked together around the world and around the clock to publish information on COVID-19 and its impact on the body as they discovered it. Dr. Bharat paved the way for advanced COVID-19 care by pioneering the double-lung transplant following severe COVID-19. Now, under Dr. Bharat's guidance, institutions around the world are implementing this procedure to save even more lives.
