Society for Cardiovascular Magnetic Resonance 2022 Cases of SCMR case series.

"Cases of SCMR" is a case series on the SCMR website (https://www.scmr.org) for the purpose of education. The cases reflect the clinical presentation, and the use of cardiovascular magnetic resonance (CMR) in the diagnosis and management of cardiovascular disease. The 2022 digital collection of cases are presented in this manuscript.

Racial disparities in women with ST elevation myocardial infarction: A National Inpatient Sample review of baseline characteristics, co-morbidities, and outcomes in women with STEMI.

BACKGROUND: A third of the patients admitted with Acute coronary syndrome (ACS) have ST-elevation myocardial infarction (STEMI). Previous studies showed that females with STEMI have higher mortality than men. HYPOTHESIS: There exist significant disparities in outcomes among women of different races presenting with STEMI. METHODS: National inpatient sample (NIS) data was obtained from January 2016 to December 2018 for the hospitalization of female patients with STEMI. We compared outcomes, using an extensive multivariate regression analysis amongst women from different races. Our primary outcome was in-hospital mortality. Secondary outcomes were revascularization use, procedure complications, and healthcare utilization. RESULTS: Of 202 223 female patients with STEMI; 11.3% were African American, 7.4% Hispanic, 2.4% Asian, and 4.3% another race. In-hospital mortality was higher in non-Caucasian groups. African American (adjusted odds ratio [aOR] 1.2; 95% confidence interval [CI]: 1.07-1.30; p < .01) and another race (aOR 1.37; 95% CI: 1.15-1.63; p < .01) had higher odds of mortality when compared with white women. African American (aOR 0.69; 95% CI: 0.62-0.72; p < .01), Hispanics (aOR 0.81; 95% CI: 0.74-0.88; p < .01), and Asian (aOR 0.79; 95% CI: 0.69-0.90; p < .01) had lower odds of percutaneous intervention (PCI) when compared with whites. African Americans had fewer odds of Coronary Artery Bypass Graft (CABG) and use of Mechanical Circulatory Support (MCS) during the index admission. Non-Caucasians had more comorbidities, complications, and healthcare utilization costs. CONCLUSION: There are significant racial disparities in clinical outcomes and revascularization in female patients with STEMI. African American women have a higher likelihood of mortality among the different races. Females from minority groups are also less likely to undergo PCI.

Anticoagulation for left ventricular thrombi secondary to COVID-Is 3 months too long?

The length of anticoagulation for thrombotic events related to COVID-19 is unknown. We present a patient with COVID-19 complicated by a thrombotic anterior STEMI and multiple left ventricular (LV) thrombi that resolved after 8 weeks of anticoagulation. We suggest a shorter length of anticoagulation with COVID-19-related LV thrombus.

Obstructing Chiari Network Facilitating Blood Flow Across a Patent Foramen Ovale Causing Hypoxia.

A 36-year-old man with progressive dyspnea and hypoxia was found to have a large, partially fenestrated Chiari network accelerating blood flow through a patent foramen ovale with preservation of an embryonic right-to-left atrial flow pattern. He underwent successful percutaneous patent foramen ovale closure with resolution of his exertional symptoms. (Level of Difficulty: Beginner.).

A Case of Acute Thrombotic Myocardial Infarction in Polyarteritis Nodosa.

This is a case of a 33-year-old male with acute myocardial infarction from complete thrombotic occlusion of the distal left anterior descending and 1st obtuse marginal artery secondary to polyarteritis nodosa. This case highlights the treatment course and need for continued awareness of vasculitis as a cause for myocardial infarction.

Outcomes of Transradial Approach to Percutaneous Coronary Intervention in End-Stage Renal Disease Patients on Dialysis.

BACKGROUND: Percutaneous coronary intervention (PCI) is increasingly performed in patients with chronic kidney disease (CKD), including in end-stage renal disease (ESRD), however studies on vascular access are limited. OBJECTIVE: We sought to describe vascular access choice and outcomes of PCI from transfemoral (TFA) compared to transradial access (TRA) in ESRD patients on dialysis. METHODS: Patients with ESRD on dialysis undergoing PCI from October 2010 to January 2017 at two hospitals in a health system reporting to the National Cardiovascular Data Registry (NCDR) CathPCI registry as well as their respective electronic medical records (Epic) were analyzed. Baseline characteristics, procedural and in-hospital outcomes were compared according to access site, TFA versus TRA. RESULTS: There were 270 patients with ESRD on dialysis who underwent PCI, 234 via the TFA and 36 via the TRA. Mean age of the patients was 67 and 67.4% were male. The TFA patients had a lower body-mass-index (BMI) (P < 0.001) and were more likely to have prior coronary artery bypass graft (CABG) (P < 0.001) and PCI of the left main coronary artery (LM) (P = 0.04). Access site cross over only occurred in one patient in each group. Bleeding within 72 h was seen in 3.8% of the TFA group and in 2.8% of the TRA group (P = 0.75). CONCLUSION: Use of TRA is uncommon in patients with ESRD on dialysis, but is feasible and associated with low complication rates, similar to TF. SUMMARY FOR THE ANNOTATED TABLE OF CONTENTS: While PCI is being increasingly performed in patients with end-stage renal disease, there are is a lack of data on vascular access for this group. This study shows that while a transradial approach TRA is less common than transfemoral (TFA), it is still a feasible option and is associated with low complications similar to TFA.

Incidental Complication From a Left Atrial Appendage Device.
