Interventional Cardiology

This cardiac subspecialty uses minimally invasive, catheter-based technologies in a cath lab to diagnose and treat coronary artery disease (CAD). The main focus in on percutaneous coronary interventions (PCI) to revascularize patients with CAD that is causing blockages resulting in ischemia or myocardial infarction. PCI mainly consists of angioplasty and implanting stents. Interventional cardiology has greatly expanded in scope over recent years to include a number of transcatheter structural heart interventions.

AHA video: Consent reform can make patient informed consumers

ORLANDO, Fla. John Spertus, MD, MPH, principal investigator of the late-breaking clinical trial, PRISM, reviewed a new way to approach the consent form process that allows for greater dialogue between patients and physicians for combined decision-making with Cardiovascular Business.

AHA video: ATLAS-ACS: Are thrombins a better target than platelets?

ORLANDOC. Michael Gibson, MD, principal investigator of the ATLAS-ACS trial, sat down with Cardiovascular Business to discuss the rationale and objectives that informed the design of the trial, as well as the much-anticipated results. The late-breaking clinical trial was presented Nov. 13 at the American Heart Association scientific sessions.

TCT: Cath lab staff must integrate, not separate

SAN FRANCISCOAs newer, more expansive procedures such as transcathter aortic valve implementation (TAVI) emerge, it will be imperative for cath labs to integrate and establish multidisciplinary teams rather than face off in turf battles, Sam Radhakrishnan, MD, said during a Nov. 10 presentation at the 23rd annual Transcatheter Cardiovascular Therapeutics (TCT) conference.

TCT: PARTNER B mortality benefits hold up at two years, as do high stroke rates

SAN FRANCISCOAt two years, in patients with symptomatic severe aortic stenosis who are not suitable candidates for surgery, transcatheter aortic valve implantation remained superior to standard therapy with incremental benefit from one to one years, reducing the rates of all-cause mortality, cardiovascular mortality and repeat hospitalization, based on the PARTNER B data presented Nov. 10, as a late-breaking clinical trial at TCT.11. However, there were more neurologic events in TAVI patients versus standard therapy with five new events between one and two years in TAVI patients.

TCT: Terminated STACCATO trial draws flak

SAN FRANCISCODespite early termination of the STACCATO trial and criticism from his colleagues, Leif Thuesen, MD, of the department of cardiology at Aarhus University Hospital in Skejby, Denmark, defend the trial, which compared a new aortic vavular treatment with surgery during a Nov. 10 press conference at the 23rd annual Transcatheter Cardiovascular Therapeutics (TCT) conference.

TCT: RIFLE aims to make radial approach standard for STEMI

SAN FRANCISCOThe use of the radial approach during PCI can help reduce bleeding complications as well as cardiovascular death in STEMI patients, according to the results of the RIFLE STEACS trial presented Nov. 10 during a late-breaking clinical trial session at the 23rd annual Transcatheter Cardiovascular Therapeutics (TCT) meeting. Trial presenter Enrico Romagnoli, MD, PhD, even went as far as to say that the radial access site should become the recommended access site for these patients undergoing PCI.

TCT: Platelet function bounce-back time is shorter with Plavix than Effient

SAN FRANCISCOTime for platelet function to return to baseline reflected the extent of platelet inhibition at 24 hours post-loading dose, and those treated with prasugrel required a longer time for recovery compared with clopidogrel, according to a scientific poster displayed Nov. 8 at the 23rd annual Transcatheter Cardiovascular Therapeutics (TCT) conference.

TCT: Cangrelor may fill unmet need for some patients undergoing surgery

SAN FRANCISCOWhen used as a bridging strategy to CABG after thienopyridine discontinuation, cangrelor achieves levels of platelet inhibition known to be associated with a low risk of thrombotic events, without increased risk of bleeding before or during CABG, according to the BRIDGE late-breaking clinical trial presented Nov. 9 at the 23rd annual Transcatheter Cardiovascular Therapeutics (TCT) conference.

Around the web

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
