Pediatric cardiac catheterization could be performed with low levels of radiation exposure using one center s as low as reasonably achievable (ALARA) protocol, researchers reported.
The strategy employed by Lisa Goto, MD, and colleagues at the Children s Hospital at Montefiore in New York City, resulted in favorable radiation levels across 95 catheterizations in 77 children weighing 20-40 kg (approximately 44-88 lbs):
Median fluoroscopy time: 11.9 minutes
Total air Kerma product: 38 mGy
Dose air product (DAP): 175 µGym
2
2/kg
Based on these findings, radiation exposure during cardiac catheterization with ALARA seems to compare favorably against published values, as Goto cited prior reports of air Kerma reaching 370-400 mGy and DAPs exceeding 2,000 µGym

Prosthetic valve endocarditis (PVE) was rare after transcatheter aortic valve replacement (TAVR) in low-risk patients, but when it did occur, the complication was associated with substantial morbidity and mortality, according to investigators from the Low Risk TAVR (LRT) study.
Incidence of PVE was 1.5% within 1 year (zero within 30 days) and 2.8% after 1 year based on an analysis of 396 low-risk TAVR recipients.
Survival was 100% in early endocarditis, but only 67% in late endocarditis, reported Giorgio Medranda, MD, of MedStar Washington Hospital Center in Washington, D.C., during the virtual meeting of the Society for Cardiovascular Angiography and Interventions (SCAI).
Of the 11 patients with PVE, the three who underwent surgical aortic valve reintervention survived. Six patients suffered embolic strokes, two of whom died after antibiotic treatment alone. These two deaths were associated with valve endocarditis, both occurring after day 500, caused by meth

Two new studies document the progress that’s been made in creating a consistent approach to cardiogenic shock care, and point to new directions as the field evolves. Both were released this week in a late-breaking session of the Society for Cardiovascular Angiography and Interventions (SCAI) 2021 virtual meeting.
Jacob Jentzer, MD (Mayo Clinic, Rochester, MN), presented pooled data confirming that SCAI’s classification system for shock severity tracks closely with mortality risk. Babar Basir, DO (Henry Ford Health System, Detroit, MI), shared final results from the National Cardiogenic Shock Initiative (NCSI) showing that an algorithm emphasizing early use of mechanical circulatory support can offer better survival for patients with acute MI complicated by cardiogenic shock (AMICS).

Research compares the ISCHEMIA trial enrollment criteria to real-world interventional practice in the U.S.
WASHINGTON, D.C. (APRIL 30, 2021) – Results from a new study find a broad range of patients who typically undergo revascularization for stable ischemic heart disease (SIHD) in the U.S. did not meet enrollment criteria for the ISCHEMIA trial. The data, which was presented April 29th as late-breaking clinical science at the Society for Cardiovascular Angiography and Interventions (SCAI) 2021 Virtual Scientific Sessions, demonstrates that a minority of SIHD patients referred for coronary intervention in contemporary practice clearly resemble those enrolled in the ISCHEMIA trial
Ischemic heart disease impacts more than 13 million people in the United States and is the leading cause of death and disability worldwide. Treatment for ischemia includes a variety of medical therapies as well as procedures like percutaneous coronary intervention (PCI) to open up clogge
