Pacemaker Needs Rise After TAVI Procedures in Spain
The incidence of implantation of a permanent pacemaker immediately after transcatheter aortic valve implantation (TAVI) increased significantly over a period of 6 years in Spain, and this rising trend remained independent of sex, age, comorbidities, or procedural volumes at the hospitals.
METHODOLOGY:
Researchers in Spain conducted a retrospective observational study using data from a national hospital discharge database to analyse the incidence of pacemaker implantation immediately after TAVI.
They analysed 20,826 episodes of TAVI performed between 2017 and 2022 in patients older than 60 years without a prior pacemaker.
The primary outcome was the implantation of a permanent pacemaker during the same hospitalisation as the TAVI procedure.
TAKEAWAY:
Overall, 16.8% of patients required the implantation of a pacemaker, with the yearly incidence of implantation increased from 15.2% to 18.2% from 2017 to 2022 (P for trend < .001).
The rising trend in pacemaker implantation was independent of sex, age, or burden of comorbidities and was not significantly influenced by the annual volume of TAVI performed at the hospitals.
IN PRACTICE:
"[The study] findings are clinically relevant and should be considered when selecting patients and optimising the procedure to reduce the need for post-TAVI pacemaker implantation," the authors wrote.
SOURCE:
This study was led by Manuel Carnero-Alcázar, MD, PhD, Hospital Clínico San Carlos, Madrid, Spain. It was published online on June 18, 2025, in Open Heart.
LIMITATIONS:
The dataset used in this study lacked information on procedural characteristics such as depth of implantation and type of valve. The retrospective and observational study design prevented the investigators from determining whether the analysed variables directly increased the pacemaker risk. Pacemaker implantation was captured only during the initial admission to the hospital.
DISCLOSURES:
This study did not receive any specific funding. The authors declared having no conflicts of interest.

The Growing Buzz Around Ancestral Wines
In the rolling hills of Valencia in Spain, winemaker Pablo Calatayud has joined forces with scientists and archaeologists to mount a small viticultural revolution—one that reaches back to pre-Roman times to recreate what have become known as ancestral wines. At his Celler del Roure, Calatayud is using large, egg-shaped clay amphorae to make wine pressed from grapes native to the region. The process is reconstructed from old texts and drawings carved into archaeological finds across the Mediterranean, including an ancient Iberian settlement that overlooks his own vineyard.

Experts issue dire warning about dangerous insects swarming across globe: 'It's an exponential curve'
Experts issue dire warning about dangerous insects swarming across globe: 'It's an exponential curve' Mosquito species typically found in tropical and subtropical climates are becoming increasingly common in Europe, bringing with them diseases such as West Nile virus and dengue. What's happening? Warmer weather and increased travel is to blame for this shift, according to Euronews. The publication cited data from the European Centre for Disease Prevention and Control that noted 1,436 cases of West Nile and 304 dengue infections were acquired in Europe in 2024, compared to just 201 over the two previous years combined. France has already had seven outbreaks of chikungunya this summer, it added. "It's an exponential curve," Jan Semenza, an environmental epidemiologist at Sweden's Umeå University, told the news site. Semenza is one of several researchers who believe that certain mosquito-borne illnesses typically found in tropical and subtropical regions, such as chikungunya and dengue, will eventually become endemic in Europe. Why are these trends concerning? This isn't limited to Europe. Scientists warn that rising global temperatures and wetter weather in regions across the globe are creating the perfect conditions for disease-carrying mosquitoes to thrive and expand their ranges. For instance, a recent study predicts that several mosquito species will spread across the Americas in coming years thanks to warming weather trends. Examples abound. For one, 2024 was already named "the worst year for dengue cases on record" by the World Mosquito Program. Health officials in Florida sounded the alarm there after several cases of locally acquired dengue in the wake of Hurricanes Helene and Milton. And many areas of the United States, such as New Jersey, are reporting earlier West Nile virus seasons this year. What's being done about mosquito-borne illnesses? Across the world, governments are trying to help minimize mosquito populations to protect citizens. There's a "bounty" program in one Manila, Philippines, neighborhood that pays residents for any mosquitoes they can round up, dead or alive. In a Florida county, officials are turning to X-ray technology to zap invasive mosquitoes. Still, Semenza told Euronews it's impossible to eliminate mosquitoes. That's why he suggests that European governments focus on other efforts, such as boosting surveillance in hotter southern countries during summer, especially near airports and other transit hubs. Euronews also summarized initiatives from across the region that are meant to reduce disease burdens. For instance, people in Spain can submit photos of mosquitoes to an artificial intelligence-powered identification app that issues an alert if the species hasn't been detected in the area before.

Department of Veterans Affairs looks to end certain abortion services for veterans
The US Department of Veterans Affairs is proposing to end certain abortion services to veterans, rolling back a Biden-era move to expand abortion rights. In a proposed rule filed Friday, the department said that it is seeking to revoke access to abortions and abortion counseling for veterans and the beneficiaries of the Civilian Health and Medical Program of the Department of Veterans Affairs. 'We take this action to ensure that VA provides only needed medical services to our nation's heroes and their families,' the department said in the filing. Under the Biden administration's rule, the department currently provides access to abortions when a pregnant veteran's life or health is at risk if their pregnancy were carried to term, or if the pregnancy was the result of rape or incest — regardless of state laws. The proposed rule would allow abortions in cases where 'a physician certifies that the life of the mother would be endangered if the fetus were carried to term,' which, according to the filing, had been permitted even before the 2022 expansion. The Biden-era rule was part of the administration's efforts to expand abortion access after Republican-led states pushed ahead with restrictions in the wake of the 2022 Supreme Court ruling that eliminated the federal right to an abortion. The VA argued at the time that it was necessary to give veterans access to abortions, saying, 'As abortion bans come into force across the country, veterans in many States are no longer assured access to abortion services in their communities, even when those services are needed.' But on Friday, President Donald Trump's VA slammed the Biden administration's rule, calling it federal overreach. 'The stated reason for (the expansion) was a reaction to a Supreme Court decision, Dobbs v. Jackson Women's Health Organization … that itself was intended to prevent federal overreach and return to States control over the provision of abortion services,' the filing states. 'Yet, the last administration used Dobbs to do the exact opposite of preventing overreach, creating a purported Federal entitlement to abortion for veterans where none had existed before and without regard to State law.' Twenty states have banned or limited access to abortion. States where abortion is limited report higher rates of maternal and infant mortality, as well as greater economic insecurity. The proposed rule will now be open for public comment for 30 days starting Monday. In his first term, Trump made good on campaign promises and appointed Supreme Court justices who helped overturn Roe v. Wade. Since that ruling, Trump has been keen to leave regulations over the issue to state governments. The Trump administration has overall been quiet on the issue of abortion in his second term. However, in June, the US Department of Health and Human Services and the Centers for Medicare & Medicaid Services moved to rescind a 2022 federal guidance to health care providers specifying that people should be able to access an abortion in the event of a medical emergency, even if state laws restrict such procedures. CNN's Veronica Stracqualursi and Jen Christensen contributed to this report.
