Impact of moderate or severe left ventricular outflow tract calcification on clinical outcomes of patients with severe aortic stenosis undergoing transcatheter aortic valve implantation with self- and balloon-expandable valves: a post hoc analysis from the SOLVE-TAVI trial
CONCLUSIONS: Moderate/severe LVOT calcification was associated with longer fluoroscopy time and an increased need for pre- and post-dilation, but not with a higher incidence of early and mid-term adverse clinical outcomes, regardless of valve type.

Thoracic Aortic < sup > 18 < /sup > F-Sodium Fluoride Activity and Ischemic Stroke in Patients With Established Cardiovascular Disease
CONCLUSIONS: In patients with established cardiovascular disease, thoracic aortic 18F-sodium fluoride activity is associated with the progression of atherosclerosis and future ischemic stroke. Arterial 18F-sodium fluoride activity identifies localized areas of atherosclerotic disease activity that are directly linked to disease progression and downstream regional clinical atherothrombotic events.

Physical and Physiologic Effects of Dobutamine Stress Echocardiography in Low-Gradient Aortic Stenosis
CONCLUSION: During DSE, aortic valve area increases with increase aortic valve gradient. Higher calcium score is associated with lower baseline aortic valve area, but the area valve area still increases with dobutamine even in presence of high calcium score.PMID:34860593 | DOI:10.1152/ajpheart.00183.2021

Calcium intake, calcium supplementation and cardiovascular disease and mortality in the British population: EPIC-norfolk prospective cohort study and meta-analysis
AbstractThe role of dietary calcium in cardiovascular disease prevention is unclear. We aimed to determine the association between calcium intake and incident cardiovascular disease and mortality. Data were extracted from the European Prospective Investigation of Cancer, Norfolk (EPIC-Norfolk). Multivariable Cox regressions analysed associations between calcium intake (dietary and supplemental) and cardiovascular disease (myocardial infarction, stroke, heart failure, aortic stenosis, peripheral vascular disease) and mortality (cardiovascular and all-cause). The results of this study were pooled with those from published pr...

What Is New in Low Gradient Aortic Stenosis: Surgery, TAVR, or Medical Therapy?
AbstractBackgroundA significant proportion of patients with aortic stenosis (AS) have discordance in severity by mean gradient/peak velocity and aortic valve area. Low gradient aortic stenosis (LG-AS) is defined when the aortic valve area is<  1 cm2 consistent with severe AS and mean aortic gradient is<  40 mmHg consistent with non-severe AS. LG-AS represents a diagnostic and therapeutic challenge.Purpose of ReviewTo summarize the different categories, diagnosis, management, and prognosis of LG-AS. LG-AS is classified as classical (ejection fraction (EF)<  50%, indexed stroke volume (SVi) <  35 ml/...

Correlates of the ratio of acceleration time to ejection time in patients with aortic stenosis: An echocardiographic and computed tomography study.
CONCLUSIONS: The AT/ET ratio is related to echocardiographic and CT-AVC indices of AS severity. However, multiple intricate factors beyond the haemodynamic and anatomical severity of AS influence the AT/ET ratio, including LV geometry, function and systolic blood pressure. These findings should be considered when assessing the AT/ET ratio in patients with AS and preserved LVEF. PMID: 31402281 [PubMed - as supplied by publisher]

The Case Files: When a Spade is Not a Spade
Turrin, Danielle DO; Sattler, Steven DO; Amodeo, Dana DO A 25-year-old Hispanic man presented to the emergency department with a complaint of three days of left-sided precordial chest pain. He described the pain as a constant 6/10 with pressure-like discomfort radiating to his left arm and the left side of his neck. He also experienced nausea, but denied any provocative or palliative factors. He said he had not experienced anything similar to this before. He had no family history of heart disease, acute myocardial infarction, or sudden cardiac death. He admitted to a 1.5 pack-per-day smoking history and social alcohol us...
