Pathophysiologic assumptions and clinical data frame a promising role for intra-aortic balloon pump (IABP) in heart failure-related cardiogenic shock (HF-CS). Currently, two randomized clinical trials (RCT) exploring this hypothesis have been published, yielding inconclusive results. We thus designed this meta-analysis to assess the efficacy of IABP in HF-CS.

The increasing use of microaxial flow pumps (mAFP) underpins the need for a comprehensive approach to manage critically ill patients in an effort to maximize the benefits of this temporary mechanical circulatory support (tMCS) while minimizing its potential complications. Multimodality cardiac imaging offers an irreplaceable array of tools to address device position, device-heart hemodynamic interaction, myocardial recovery assessment, and identification of complications. This review provides a comprehensive and pragmatic summary of the cardiovascular imaging modalities currently available throughout the pathway of care of mAFP-supported patients, from device insertion, to intensive cardiac care hemodynamic monitoring, weaning guidance, and myocardial recovery assessment.

Invasive hemodynamic monitoring provides essential information for managing acute heart failure (AHF) and cardiogenic shock (CS) patients, aiding circulatory shock phenotyping and in individualized and hemodynamically-based therapeutic management. The hemodynamic trajectory after the initial care bundle has been provided refines prognostication and anticipates hospital outcomes. Invasive hemodynamic monitoring also tracks the clinical response to supportive measures, providing objective background for therapeutic escalation/de-escalation, facilitating titration of vasoactive/temporary mechanical circulatory support (tMCS) to achieve an optimal balance between native heart function and device assistance, and allowing for a repeated reassessment of hemodynamics during the support weaning phase.

The clinical outcomes of patients with left ventricular assist devices (LVAD) have steadily improved, unveiling late right ventricular failure (RVF) and aortic regurgitation (AR) as drivers of long-term mortality. The continuous-flow LVAD physiology and the patient's pre-existing features predispose to these complications, recently labeled hemodynamic-related events (HDREs). We present the case of an LVAD carrier complicated by both late RVF and AR, in which a comprehensive hemodynamic and echo-guided ramp test was carried out.

Background: ST-segment elevation myocardial infarction (STEMI) remains a major cause of morbidity and mortality, with survivors facing high risk of heart failure, recurrent ischemia, and arrhythmias. Risk stratification traditionally relies on echocardiography, while cardiac magnetic resonance (CMR) is the most effective tool for predicting adverse outcomes. However, its routine use is limited by accessibility, cost, and logistical constraints.

Background: Transcatheter edge-to-edge repair (TEER) for severe functional mitral regurgitation (FMR) in patients with reduced left ventricular ejection fraction (LVEF) may lead to an acute increase in left ventricular afterload, termed afterload mismatch (AM). This study aimed to redefine AM clinically, analyse its determinants, and assess its prognostic impact post-TEER in FMR patients.

Methods: A multicenter case-control study was conducted, involving FMR patients with LVEF ≤35% undergoing TEER.

Aims: The diagnosis of cardiogenic shock (CS) relies upon signs and/or symptoms of end-organ hypoperfusion. The combination of hypoperfusion and systemic congestion identifies patients at particularly high risk. This study evaluated organ perfusion pressure (OPP), calculated as mean arterial pressure minus invasive central venous pressure, as a predictor of outcomes in CS.

Background: Angiotensin receptor-neprilysin inhibitor (ARNI) intolerance is common in patients with advanced heart failure (AdHF) and may be associated with worse prognosis. During right heart catheterization (RHC), afterload reduction induced by vasodilator challenge may reproduce the hemodynamic effects of ARNI. Through sodium nitroprusside (NTP) infusion, we characterized the hemodynamic mechanisms of ARNI intolerance and explored its prognostic relevance in AdHF.

Article Synopsis
  • Coronary access (CA) and percutaneous coronary intervention (PCI) can be more difficult after valve-in-valve transcatheter aortic valve replacement (ViV-TAVR), especially with certain valve designs.* -
  • A study found that the ACURATE neo2 valve led to significantly better success rates for both CA (96.7%) and PCI (98.3%) compared to the Evolut PRO+ valve (75% and 85%, respectively).* -
  • The design differences between the valves affected procedural approaches, with ACURATE neo2 allowing for easier access due to a greater valve-to-anatomy distance.*
