Older patients pinch coronary artery illness scheduled for transcatheter aortic valve replacement (TAVR) had comparable outcomes sloppy of whether they underwent percutaneous coronary involution (PCI) earlier TAVR, according to findings from nan PRO-TAVI study presented astatine nan American College of Cardiology's Annual Scientific Session (ACC.26).
TAVR is simply a minimally invasive process successful which a caller aortic valve is delivered via a catheter, astir commonly done nan femoral artery successful nan groin, and implanted wrong nan diseased autochthonal valve. PCI, besides called angioplasty, is simply a minimally invasive process successful which a stent is delivered via a catheter, typically done nan radial artery successful nan arm, to unfastened narrowed aliases blocked coronary arteries and reconstruct capable humor travel to nan bosom muscle.
For patients who person some a malfunctioning valve and blocked arteries (coronary artery disease), location has been a deficiency of grounds regarding nan optimal operation and timing of procedures, and communal practices alteration by region. In Europe, wherever TAVR is mostly reserved for older and higher-risk patients, physicians person tended to defer PCI until aft TAVR. In nan United States, wherever patients undergoing TAVR thin to beryllium younger and healthier, it is much communal to urge patients acquisition PCI earlier TAVR.
The proceedings was conducted successful nan Netherlands, and nan findings support nan communal believe there, wherever physicians for illustration to omit PCI earlier TAVR unless location is simply a clear denotation that PCI is necessary. According to nan results, omitting PCI earlier TAVR did not consequence successful immoderate summation successful nan consequence of death, bosom attack, changeable aliases mean to superior bleeding.
"For aged TAVR patients pinch concomitant coronary artery disease, I deliberation it's safe to first do TAVR and spot if patients will still person complaints astir thorax symptom aliases tightness," said Michiel Voskuil, MD, PhD, an interventional cardiologist and professor astatine University Medical Center Utrecht successful nan Netherlands and nan study's lead author. "We tin hold and, if they still person complaints afterward, only past do PCI."
The proceedings enrolled 466 patients astatine 12 sites successful nan Netherlands betwixt 2021-2024. The median property of participants was complete 80 years, 36% were women, and patients wide reflected a high-risk population, emblematic for patients undergoing TAVR successful Europe. All participants had coronary artery illness pinch important blockage successful nan arteries. Half of nan patients were randomly assigned to person PCI earlier their TAVR procedure, and half were assigned to person TAVR first and only acquisition PCI afterward if necessary.
The superior endpoint was a composite of decease from immoderate cause, bosom attack, changeable aliases mean to terrible bleeding astatine 12 months. This composite endpoint occurred successful 25.8% of those who underwent PCI earlier TAVR and 24.1% of those who deferred PCI. This consequence met nan trial's prespecified period for non-inferiority and did not show nan superiority of either approach, indicating that they are balanced successful position of expected outcomes.
The 2 study groups did show a important quality successful nan complaint of awesome bleeding, which was analyzed arsenic a secondary outcome. Among those who underwent PCI earlier TAVR, 14.8% knowledgeable awesome bleeding, compared pinch 6.2% of those who deferred PCI. Researchers said this summation successful bleeding was apt attributable to nan dual antiplatelet therapy that is prescribed pursuing PCI and astir bleeds occurred astir nan clip of nan TAVR procedure, though location was nary excess mortality associated pinch awesome bleeding.
Overall, astir 10% of patients who were assigned to defer PCI yet underwent PCI owed to continuing aliases worsening symptoms pursuing their TAVR.
Researchers said nan results are astir applicable to Europe and nan Netherlands successful particular, wherever TAVR is mostly utilized successful an aged population. The findings whitethorn not needfully construe to different countries and populations wherever it is much communal for younger and comparatively healthier patients to acquisition TAVR.
"This study is astir intermediate and high-risk patients only," Voskuil said. "For low-risk TAVR patients who are mostly younger, this mobility remains unfastened to chat and location is room for caller tests to find what is nan much favorable approach."
The study was funded by The Netherlands Organisation for Health Research and Development (ZonMw).
This study was simultaneously published online successful The Lancet at nan clip of presentation.
Voskuil will coming nan study, "Transcatheter Aortic Valve Implantation Without Routine Percutaneous Coronary Intervention: A Randomized Controlled Trial," connected Sunday, March 29, astatine 4:00 p.m. CT / 21:00 UTC successful nan Main Tent, Great Hall.
