When 83-year-old Grandma Zhang clearly heard the doctor say on the operating table, "The valve has been successfully positioned," she might not have known that she was experiencing a revolutionary breakthrough in heart surgery.New research presented at the European Society of Cardiology Congress 2025 (ESC Congress 2025) shows that most patients, like Grandma Zhang, who undergo transcatheter aortic valve replacement (TAVR)Surgery can be safely performed under local anesthesia without deep sedation.。This discovery not only rewrites the treatment paradigm for cardiac surgeries in elderly patients but also brings good news to millions of senior patients with valvular disease.

What is TAVR surgery? Why is the anesthesia method so important?

TAVR, fully known as Transcatheter Aortic Valve Replacement, is a minimally invasive interventional technique used to treat severe aortic valve stenosis. Unlike traditional open-heart surgery, doctors deliver a folded artificial valve through a small incision in the groin or chest, advancing it via blood vessels to the diseased aortic valve position and deploying it, all without opening the chest cavity. This procedure is particularly suitable for elderly and frail patients —Studies show that the median age of TAVR patients is 83 years, nearly 60% are female, and these populations often cannot tolerate the trauma of traditional surgery and the risks of general anesthesia.

Traditional TAVR procedures typically require deep sedation or general anesthesia, along with the placement of various invasive devices such as central venous catheters, arterial monitoring catheters, and urinary catheters. However, this multicenter study, presented at the ESC 2025 conference, found:The "Minimalist TAVR" approach, which uses local anesthesia and a simplified procedure, demonstrates even better outcomes in key safety metrics compared to traditional methods.。

Minimalist TAVR: The Medical Wisdom of "Less is More"

The researchers divided the patients into two groups for comparison:

• Minimalist Group
  Only local anesthesia is used, without sedatives, additional monitoring catheters, or urinary catheters.

• Traditional Group
  Routine sedation, with the conventional use of various auxiliary catheters

The results are encouraging: the composite risk of death, bleeding complications, infection, or neurological events within 30 days was 22.9% in the minimalistic group and 25.8% in the conventional group. More importantly, about 80% of patients did not need to switch protocols throughout the procedure, with only 19% requiring a shift to traditional care due to pain or discomfort — meaning the majority of patients can safely complete the surgery while awake.

"This颠覆了我们对心脏手术的认知。" 研究主导者、德国莱比锡心脏中心的Mohamed Abdel-Wahab教授解释道，"就像拔牙可以只用局部麻醉一样，复杂心脏手术也能通过精准麻醉实现'清醒治疗'，减少不必要的医疗干预。"

Valve Design Holds Hidden Secrets: Why Is This Withdrawn Product Worth Attention?

The study simultaneously compared the performance of two mainstream self-expanding valves:

• Boston Scientific Acurate neo2 Valve: Major Adverse Event Rate 15.4%
• Medtronic Evolut Series Valves: Incidence of Major Adverse Events 30.4%

The key to the gap lies inPermanent Pacemaker Implantation (PPMI) Rate——Acurate neo2 is significantly lower. This advantage stems from its unique design: the use of "active sealing technology" to fit the aortic valve annulus, minimal interference with the cardiac conduction system by the valve stent, and precise positioning achieved through "top-down release" technology, reducing the impact on the heart's electrophysiological system.

Regrettably, Boston Scientific has exited the TAVR market, but experts emphasize: "This design concept with a low PPMI rate is worth emulating by all valve developers.。" In the future, valves may focus more onAnatomical AdaptabilityAndTissue Compatibility, while ensuring the sealing effect and reducing interference with the cardiac conduction system.

Which Patients Are Suitable for Minimalist TAVR? Doctors Recommend This

Although studies show that 80% of patients are suitable for the minimalist approach, it is not for everyone. Current clinical observations have found that patients with better preoperative assessment status, appropriate vascular conditions, and milder valve calcification are more likely to benefit from it. Professor Abdel-Wahab particularly reminded: "Elderly patients have significant individual differences, and a comprehensive preoperative multidisciplinary evaluation by an experienced cardiac team, including echocardiography, CT angiography, and other thorough examinations, is essential."

For patients and their families, here are some practical suggestions:

• Discuss preferences for anesthesia plans with the doctor before surgery, and explain concerns about sedation.
• Understanding the Minimalist TAVR Experience and Case Volume of the Surgical Team
• Postoperative attention should be paid to bleeding at the puncture site, swelling of the lower limbs, etc.
• Elderly patients especially need to focus on postoperative anticoagulation management and regular follow-ups.

The Ultimate Goal of Medical Advancement: Making Treatment More Human-centered

From open-heart surgery to minimally invasive intervention, from general anesthesia to local anesthesia, every iteration of TAVR technology reflects the concept of "patient-centered" care. For elderly patients over 80 years old, avoiding deep sedation means less risk of postoperative delirium, faster recovery, and shorter hospital stays. As one patient who underwent the minimalist TAVR procedure said, "Being able to hear the doctor's encouragement during the surgery and knowing everything was going smoothly provided a sense of security that is irreplaceable."

This research from ESC 2025 tells us:The best medical technology not only cures diseases but also respects patients' feelings. With the continuous optimization of valve design and the ongoing simplification of surgical procedures, more heart patients like Grandma Zhang will regain their "heart" life in a state of clarity and peace.
