Measurement of stroke volume with echocardiography compared to gold standard cardiac magnetic resonance imaging An observational study
The assessment of Doppler-derived left ventricular outflow tract (LVOT) stroke volume (SV) is fundamental in outpatient, perioperative and critical care echocardiography.1 Calculation of SV allows assessment of the severity of aortic stenosis (AS) and evaluation of the haemodynamic state during undifferentiated hypotension.2 The use of focused transthoracic echocardiography (TTE) has appeal in a critical care environment, where after a single measurement of the LVOT area, pulsed wave Doppler velocity time integral (VTI) in the LVOT is used to calculate LVOT SV.

Economic Outcomes of Transcatheter Versus Surgical Aortic Valve Replacement in Patients with Severe Aortic Stenosis and Low Surgical Risk: Results from the PARTNER 3 Trial
CONCLUSIONS: For patients with severe aortic stenosis and low surgical risk similar to those enrolled in the PARTNER 3 trial, transfemoral TAVR with the SAPIEN 3 valve is cost saving compared with SAVR at 2 years and is projected to be economically attractive in the long run as long as there are no substantial differences in late death between the 2 strategies. Long-term follow-up will be critical to ultimately determine the preferred treatment strategy for low-risk patients from both a clinical and economic perspective.PMID:37154049 | DOI:10.1161/CIRCULATIONAHA.122.062481

Left-ventricular reverse remodeling after transcatheter aortic valve implantation in patients with low-flow low-gradient aortic stenosis
CONCLUSIONS: The majority of patients with LFLG AS show LVRR after TAVI, which is associated with favorable outcome. An SVI of < 25ml/m2, LVEF < 30% and Zva < 5mmHg/ml/m2 represent predictors of LVRR.PMID:37119968 | DOI:10.1016/j.hjc.2023.04.009

Proof of concept study on coronary microvascular function in low flow low gradient aortic stenosis
Conclusions CMD is more severe in patients with LFLGAS compared with NFHGAS and is associated with low-flow state, left atrial dysfunction and reduced cardiac performance.

Lipoprotein (a), Inflammation, and Atherosclerosis
J Clin Med. 2023 Mar 27;12(7):2529. doi: 10.3390/jcm12072529.ABSTRACTGrowing evidence has shown that high levels of lipoprotein (a) (Lp(a)) and chronic inflammation may be responsible for the residual risk of cardiovascular events in patients managed with an optimal evidence-based approach. Clinical studies have demonstrated a correlation between higher Lp(a) levels and several atherosclerotic diseases including ischemic heart disease, stroke, and degenerative calcific aortic stenosis. The threshold value of Lp(a) serum concentrations associated with a significantly increased cardiovascular risk is >125 nmol/L (50 mg/dL...

Transcatheter vs Surgical Aortic Valve Replacement in Pure Native Aortic Regurgitation
CONCLUSIONS: In Medicare patients with pure native AR, TAVR with the current commercially available transcatheter valves has comparable short-term outcomes. Although long-term outcomes were inferior to SAVR, the possibility of residual confounding, biasing long-term outcomes, given older and frailer TAVR patients, cannot be excluded.PMID:36967709 | DOI:10.1016/j.athoracsur.2022.09.016

Suitability of TAVI in low-risk patients
Nature Reviews Cardiology, Published online: 21 March 2023; doi:10.1038/s41569-023-00862-6In the Evolut Low Risk study, transcatheter aortic valve implantation in low-risk patients with severe aortic stenosis compared favourably with surgical aortic valve replacement in terms of all-cause mortality or disabling stroke at 3 years.

Clonal Hematopoiesis and the Heart: a Toxic Relationship
Curr Oncol Rep. 2023 Mar 15. doi: 10.1007/s11912-023-01398-1. Online ahead of print.ABSTRACTPURPOSE OF REVIEW: Clonal hematopoiesis (CH) refers to the expansion of hematopoietic stem cell clones and their cellular progeny due to somatic mutations, mosaic chromosomal alterations (mCAs), or copy number variants which naturally accumulate with age. CH has been linked to increased risk of blood cancers, but CH has also been linked to adverse cardiovascular outcomes.RECENT FINDINGS: A combination of clinical outcome studies and mouse models have offered strong evidence that CH mutations either correlate with or cause atheroscle...
