Effects of sotatercept on haemodynamics and right heart function: analysis of the STELLAR trial
Conclusion In pre-treated patients with PAH, sotatercept demonstrated substantial improvements in PA pressures, PA compliance, PA–RV coupling and right heart function.

Preoperative higher right ventricular stroke work index increases the risk of de novo aortic insufficiency after continuous-flow left ventricular assist device implantation
This study investigated the influence of preoperative hemodynamic parameters on de novo AI in CF-LVAD recipients. We reviewed 125 patients who underwent CF-LVAD implantation without concomitant AV surgery between 2005 and 2018. De novo AI was defined as moderate or severe AI in those with none or trivial preoperative AI. During mean 30  ± 16 months of CF-LVAD support, de novo AI-free rate was 86% and 67% at 1 and 2 years, respectively. Multivariable analysis showed that higher right ventricular stroke work index (RVSWI) (hazard ratio, 1.12 /g/m2/beat; 95% confidence interval, 1.00 –1.20;p = 0.047) and trivial ...

No association between pulmonary artery catheter use and postoperative complications in off-pump coronary artery bypass grafting: a single-center pilot study
CONCLUSIONS: Pulmonary artery catheterization did not improve the clinical outcomes in off-pump coronary artery bypass grafting in this pilot study.PMID:37458732 | DOI:10.23736/S0021-9509.23.12710-8

Echocardiographic pressure –strain loop‐derived stroke work of the right ventricle: validation against the gold standard
ConclusionsIntegrated echo measurement of pressure –strain loop-derived SW correlates with PV loop-based assessment of RV SW. Wasted work correlates with invasive measures of load-independent RV function. Given the methodological and anatomical challenges of RV work assessment, evolution of this approach by incorporating more elaborated echo analy sis data and an RV reference curve might improve its reliability to mirror invasively assessed RV SW.

Zero-contrast imaging for the assessment of transcatheter aortic valve implantation in candidates with renal dysfunction
CONCLUSION: The proposed contrast-free imaging protocol appears to be a promising clinical tool for pre-TAVI evaluation in patients with severe renal dysfunction.PMID:37350345 | DOI:10.1080/0886022X.2023.2224888
