When the Rolling Stone’s Mick Jagger underwent heart valve replacement surgery in New York recently, according to media reports the doctor in France who invented the technique took a modest bow.
“I am not especially a fan of the Rolling Stones but I am pleased with the outcome,” said Alain Cribie, director of cardiology at the University of Rouen’s Charles Nicolle Hospital. “What is moving is to think about all the patients who have benefited from the procedure.”
“I’m feeling much better now and on the mend,” Jagger, 75, wrote on Twitter.
Weighing his words carefully, the cardiologist who pioneered the technique in 2002 does not have the allure of a rock star, but in his field, many colleagues see him that way.
Known as transcatheter aortic valve replacement (TAVR), his method has gradually replaced open-heart surgery for repairing the valve that allows the delivery of blood through the aorta.
The most common — and serious — of valve diseases, age-related aortic stenosis occurs when the valve narrows and hardens with calcium deposits.
Valve replacement has historically been done by opening the chest surgically, stopping the heart, and placing the patient on a heart and lung blood machine — all, of course, under general anesthesia.
More than 200,000 such procedures are performed every year worldwide, according to NewHeartValve in Britain.
Cribier’s technique, done under local anesthesia, is minimally invasive by comparison and has far shorter recovery times.
A surgeon or cardiologist accesses the femoral artery with an incision near the groin to insert a catheter fitted with a replacement valve inside a collapsed stent, and a balloon for inflating it.
The new heart valve, once expanded, pushes the old one out of the way and takes over the job of regulating blood flow.
“It has revolutionized patient care in this area,” Montpellier-based cardiologist Stephane Cade said.
Since first performing the surgery in 2002, Cribier had trained dozens of doctors around the world.
At first, TAVR was reserved for patients too weak or old to undergo open-heart surgery, but over the last decade, its use has been expanded to those for whom the traditional approach poses an “intermediate risk.”
Since 2009, 400,000 patients in 65 countries have undergone the procedure, Cribier said.
Those numbers could now expand rapidly.
A study based on clinical trials published last month in The New England Journal of Medicine concluded that TAVR is safer and yields better results for “low-risk patients” as well.
“I must say reading the study brought tears to my eyes,” Cribier said.
He said the idea first came to him in the 1980s, adding: “At the time, we let patients over 75 simply die — we didn’t operate.”
However, one unknown is the lifespan of the new valves, which are made from bovine tissue.
In the sweltering streets of Jakarta, buskers carry towering, hollow puppets and pass around a bucket for donations. Now, they fear becoming outlaws. City authorities said they would crack down on use of the sacred ondel-ondel puppets, which can stand as tall as a truck, and they are drafting legislation to remove what they view as a street nuisance. Performances featuring the puppets — originally used by Jakarta’s Betawi people to ward off evil spirits — would be allowed only at set events. The ban could leave many ondel-ondel buskers in Jakarta jobless. “I am confused and anxious. I fear getting raided or even
Eleven people, including a former minister, were arrested in Serbia on Friday over a train station disaster in which 16 people died. The concrete canopy of the newly renovated station in the northern city of Novi Sad collapsed on Nov. 1, 2024 in a disaster widely blamed on corruption and poor oversight. It sparked a wave of student-led protests and led to the resignation of then-Serbian prime minister Milos Vucevic and the fall of his government. The public prosecutor’s office in Novi Sad opened an investigation into the accident and deaths. In February, the public prosecutor’s office for organized crime opened another probe into
RISING RACISM: A Japanese group called on China to assure safety in the country, while the Chinese embassy in Tokyo urged action against a ‘surge in xenophobia’ A Japanese woman living in China was attacked and injured by a man in a subway station in Suzhou, China, Japanese media said, hours after two Chinese men were seriously injured in violence in Tokyo. The attacks on Thursday raised concern about xenophobic sentiment in China and Japan that have been blamed for assaults in both countries. It was the third attack involving Japanese living in China since last year. In the two previous cases in China, Chinese authorities have insisted they were isolated incidents. Japanese broadcaster NHK did not identify the woman injured in Suzhou by name, but, citing the Japanese
RESTRUCTURE: Myanmar’s military has ended emergency rule and announced plans for elections in December, but critics said the move aims to entrench junta control Myanmar’s military government announced on Thursday that it was ending the state of emergency declared after it seized power in 2021 and would restructure administrative bodies to prepare for the new election at the end of the year. However, the polls planned for an unspecified date in December face serious obstacles, including a civil war raging over most of the country and pledges by opponents of the military rule to derail the election because they believe it can be neither free nor fair. Under the restructuring, Myanmar’s junta chief Min Aung Hlaing is giving up two posts, but would stay at the
