Insights
Cardiac procedural deferrals during COVID-19 varied by urgency and hospital burden. Cardiologists noted increased late heart attacks and deaths, independent of local COVID-19 severity, highlighting healthcare access concerns.
Area of Science:
- Cardiology
- Public Health
- Infectious Diseases
Background:
- The COVID-19 pandemic necessitated widespread cardiac procedural deferrals.
- Understanding factors influencing these deferrals and their impact is crucial for patient care.
- Cardiologists' perspectives on these changes are vital for assessing implications.
Purpose of the Study:
- To examine factors affecting cardiac procedural deferral variability during the COVID-19 pandemic.
- To assess interventional cardiologists' perspectives on the implications of these deferrals.
- To analyze the relationship between COVID-19 burden, procedural urgency, and deferral rates.
Main Methods:
- A web-based survey was distributed by the Society for Cardiovascular Angiography and Interventions and the American College of Cardiology Interventional Council.
- The survey targeted cardiac catheterization laboratory directors and interventional cardiologists across the United States.
- Data from 414 responses across 48 states were analyzed, correlating COVID-19 burden with procedural volumes and deferral patterns.
Main Results:
- Cardiac procedural deferrals varied significantly based on procedural urgency and hospital COVID-19 burden (p < .001).
- Volumes for percutaneous coronary intervention dropped by 55% and transcatheter aortic valve replacement by 64%.
- Cardiologists reported increased late-presenting ST-elevation myocardial infarctions and deaths, independent of local COVID-19 burden.
Conclusions:
- Cardiac procedural deferrals during the pandemic were influenced by urgency and hospital COVID-19 burden.
- Despite deferrals, patients experienced adverse outcomes like late myocardial infarctions, underscoring the risks of delayed care.
- Ensuring the safety and importance of seeking timely cardiovascular care during public health crises is paramount.
Abstract:
We aimed to examine factors impacting variability in cardiac procedural deferral during the COVID-19 pandemic and assess cardiologists' perspectives regarding its implications. Unprecedented cardiac procedural deferral was implemented nationwide during the COVID-19 pandemic. A web-based survey was administered by Society for Cardiovascular Angiography and Interventions and the American College of Cardiology Interventional Council to cardiac catheterization laboratory (CCL) directors and interventional cardiologists across the United States during the COVID-19 pandemic. Among 414 total responses, 48 states and 360 unique cardiac catheterization laboratories were represented, with mean inpatient COVID-19 burden 16.4 ± 21.9%. There was a spectrum of deferral by procedure type, varying by both severity of COVID-19 burden and procedural urgency (p < .001). Percutaneous coronary intervention volumes dropped by 55% (p < .0001) and transcatheter aortic valve replacement volumes dropped by 64% (p = .004), with cardiologists reporting an increase in late presenting ST-elevation myocardial infarctions and deaths among patients waiting for transcatheter aortic valve replacement. Almost 1/3 of catheterization laboratories had at least one interventionalist testing positive for COVID-19. Salary reductions did not influence procedural deferral or speed of reinstituting normal volumes. Pandemic preparedness improved significantly over time, with the most pressing current problems focused on inadequate testing and staff health risks. During the COVID-19 pandemic, cardiac procedural deferrals were associated with procedural urgency and severity of hospital COVID-19 burden. Yet patients did not appear to be similarly influenced, with cardiologists reporting increases in late presenting ST-elevation myocardial infarctions independent of local COVID-19 burden. The safety and importance of seeking healthcare during this pandemic deserves emphasis.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
