The goal of this clinical trial is to learn if acute transcatheter aortic valve implantation (TAVI) is superior to standard treatment (stabilization in an intensive care unit and TAVI subsequently) to treat cardiogenic shock in patients with critical severe aortic stenosis. The main questions it aims to answer are: • Does acute TAVI increase survival compared with standard treatment? Participants will: * Undergo either TAVI within 12 hours after admission or stabilization and TAVI 72 hours or more after admission * Visit an outpatient clinic and be evaluated for quality of life and heart function
NCT04295252
The study will provide data on profile, management, outcome, and evolution over time of cardiogenic shock patients admitted to the Intensive Coronary Care Units
NCT07515508
The goal of this observational study is to learn whether information collected during routine hospital care, together with blood and urine samples, can help doctors better identify different types of cardiogenic shock and better predict outcomes in adults hospitalized with acute heart failure and cardiogenic shock. The main question is whether clinical findings, imaging results, and biomarkers, including sex-specific factors, are associated with the risk of death within 30 days. Participants will not receive an experimental treatment. Researchers will collect data from routine care, collect additional blood and urine samples for biobanking, and follow participants after hospital discharge
NCT05168462
Rationale: Pump failure due to acute myocardial infarction (AMI) can lead to cardiogenic shock (CS): a state of low blood flow to end-organs with subsequent multi-organ failure that is associated with high mortality rated. The first line pharmacologic treatment strategy in CS is noradrenaline. This vasopressor drug is used to maintain adequate blood pressures. The assumption is that a mean arterial blood pressure (MAP) ≥ 65 mmHg will improve flow and thereby tissue perfusion of myocardium and other tissues (e.g. renal). However, there is no evidence that an increase in MAP, if achieved by noradrenaline, leads to greater end-organ blood flow and better outcomes. Objective: With this study the investigators aim to investigate the (cost-)effectiveness of reduced noradrenaline in patients with CS by using a lower MAP target of ≥ 55 mmHg, compared to ≥ 65 mmHg. The investigators hypothesize that reduced use of noradrenaline will improve overall survival and decrease renal failure requiring renal replacement therapy. Study design: Open label, randomized controlled multicenter trial Study population: Adults patients with CS due to AMI Intervention: Treatment strategy of reduced noradrenaline, by using a lower MAP target ( ≥ 55 mmHg). Main study endpoint: composite of all-cause mortality and severe renal failure leading to renal replacement therapy within 30-days after randomization.

Pilot Prospective Randomized Unblinded Pragmatic Trial of Pulmonary Artery Hemodynamic Monitoring Following Hospitalization for Cardiogenic Shock
NCT07470814
Acute myocardial infarction complicated by cardiogenic shock (AMI-CS) represents the most life-threatening subtype of acute cardiovascular diseases. Current clinical management of AMI-CS in China is plagued by multiple structural challenges, including a rapidly aging patient population, inequitable distribution of medical resources, the absence of standardized care models, and poor applicability of international risk stratification tools. Owing to ethnic disparities in disease presentation and the low penetration of mechanical circulatory support (MCS) devices in China, international clinical evidence for AMI-CS diagnosis and treatment cannot be directly translated into local clinical practice. Furthermore, the lack of a standardized multidisciplinary collaborative care system has become a critical bottleneck hindering the reduction of AMI-CS mortality. To address these unmet clinical needs, this study aims to develop a tailored multidisciplinary collaborative care system adapted to China's healthcare landscape and to evaluate its clinical efficacy and safety via a prospective multicenter registry study. The study will establish a tiered collaborative network encompassing healthcare institutions of all levels and formulate standardized clinical pathways and risk stratification strategies for AMI-CS. A total of at least 1,000 AMI-CS patients will be enrolled in the study, with systematic collection of their clinical characteristics, multidisciplinary interventions, MCS utilization, and prognostic outcomes to build a high-quality real-world database. Based on the registry data, a China-specific risk stratification model for AMI-CS will be developed by integrating clinical metrics, biomarkers, and imaging features. This study will assess the benefits and risks of MCS devices used alone or in combination, and evaluate the implementation effectiveness of the multidisciplinary collaborative care system by comparing core outcomes-including 30/180-day all-cause mortality, severe complication rates, and door-to-balloon times-before and after the system's rollout and across healthcare institutions of different tiers. Additionally, this study will explore the key factors influencing the efficacy of multidisciplinary collaboration to inform the optimization of the care system. This study is expected to validate the feasibility and effectiveness of the multidisciplinary collaborative care system in the Chinese clinical setting, reduce AMI-CS mortality, narrow the gap in care capacity across different-tier hospitals, and fill the evidence gap in multidisciplinary AMI-CS management for the Chinese population.

There are two primary goals of this multicenter clinical trial that combines an FDA device trial and a phase II drug trial in the same study cohort. These two goals are to: 1. To evaluate the safety and effectiveness of the Cardiohelp Device for VA-ECMO (heart-lung support) for up to 30 days of support in children with severe heart failure with the goal to support its FDA clearance in children. 2. To evaluate heparin versus bivalirudin as the primary blood thinner (anticoagulant) in a randomized trial of children supported with the Cardiohelp ECMO System with the goal to plan a phase III (pivotal) randomized clinical trial The main questions the Cardiohelp single-arm trial seeks to answer are: * What is the safety and effectiveness of the Cardiohelp device for pediatric ECMO? * Should the Cardiohelp device be FDA-cleared for children based on the results of the study? * What are the optimal performance specifications of the Cardiohelp device in children? The main questions the blood thinner randomized trial seeks to answer are: * Which blood thinner is more promising (i.e., more effective and safer) in children on the Cardiohelp device? * How should a pivotal trial of heparin vs. bivalirudin be designed so it is the most informative and efficient to determine the best blood thinner? Children who are receiving the Cardiohelp device will be approached and consented to participate if interested. For the Cardiohelp device trial, participants will undergo a standardized data collection to estimate survival to 30 days and the prevalence of serious adverse events like stroke, bleeding, and hemolysis. For the blood thinner randomized trial, participants will be randomized 1:1 to blood thinner strategy to determine which blood thinner has the fewest bleeding and clotting complications. For the Cardiohelp single-arm trial, participant outcomes will be compared to performance goals (PG) derived from the ECMO literature. For the blood thinner randomized trial, the amount of bleeding and clotting will be measured. The study is funded by an R01 grant from the FDA's Office of Orphan Product Development (OOPD).

Abiomed IMPELLA-RT-DAQ - Impella Real Time Data AcQuisition
NCT07184593
The goal of this observational study is to evaluate whether whole blood H3.1 nucleosome levels can predict 30-day mortality in adult critically ill patients admitted to the ICU with conditions such as sepsis, septic shock, cardiogenic shock, severe trauma, post-cardiac arrest, acute brain injury, or severe acute pancreatitis. The main questions it aims to answer are: Do initial whole blood H3.1 nucleosome levels predict 30-day mortality in critically ill patients? Are whole blood nucleosome measurements using a novel point-of-care device correlated with traditional plasma chemiluminescence immunoassays (ChLIA)? If there is a comparison group: Researchers will compare point-of-care whole blood nucleosome results with plasma ChLIA assays to see if the device provides reliable and feasible bedside measurements. Participants will: Provide blood samples at admission, 6h, Day 1, Day 3, and Day 7 for nucleosome analysis. Undergo point-of-care H3.1 nucleosome measurement and parallel plasma storage for ChLIA testing. (If applicable, in acute brain injury patients with external ventricular drains) provide daily cerebrospinal fluid samples until Day 5, only if otherwise discarded. Have standard ICU data (SOFA, SAPS II, etc.) collected as part of routine care.

Accurate hemodynamic monitoring is critical in cardiothoracic surgery, where left atrial pressure (LAP) serves as the gold standard for assessing left-sided cardiac filling pressures. However, its invasive nature limits use, favoring pulmonary capillary wedge pressure (PCWP) via Swan-Ganz catheter as a surrogate. Despite widespread use, evidence on their agreement under dynamic conditions-such as varying cardiac index (CI) flows during cardiopulmonary bypass (CPB) or left ventricular (LV) unloading-remains inconsistent and unstudied in adult cardiac surgery. Existing data show conflicting correlations: one study found that PCWP 35% higher than LAP in non-surgical patients, and another study found closer alignment in specific cohorts. This knowledge gap carries clinical urgency, as decisions on pulmonary edema management, vasopressor use, and LV decompression rely on these measurements. Building on Laplace's law, we hypothesize that LV unloading reduces ventricular wall stress (afterload), lowering myocardial oxygen demand and altering the LAP-PCWP relationship. Elevated CI during CPB may further distort this interaction via increased pulmonary-left atrial pressure gradients. The primary objective is to determine if PCWP reliably reflects LAP under standard CI-flow (2.4 L/min/m²) without unloading, using Bland-Altman analysis (±5 mmHg clinical margin). Secondary objectives assess agreement at other CI levels (1.8-2.6 L/min/m²), LV unloading effects, and patient/surgical variable impacts.

NCT07099014
Midazolam and propofol are the most used intravenous (IV) sedative agents, but their use is associated with well-known adverse effects such as accumulation, myotoxicity, tachyphylaxis, and unpredictable wake-up time. For benzodiazepines, an increased tolerance, possible accumulation after long-term use, and an increased risk of acute withdrawal syndrome are reported. In patients on extracorporeal membrane oxygenation (ECMO) for cardiogenic shock, the negative hemodynamic effects of these drugs are a particular matter of concern. Besides the extracorporeal circuit itself may affect the pharmacokinetics of these IV sedatives. Indeed, drug sequestration in ECMO circuits is a well-known phenomenon influenced by drug chemo-physical properties. Given the large surface area of tubing and membrane, considerable quantities of drugs used in ECMO patients may be sequestered over a period, resulting in a significant increase in their volume of distribution. Similarly, frequent hemodilution and organ dysfunction would also contribute to an increase in the volume of distribution. Propofol, which is lipophilic is significantly sequestrated in the circuit. Consequently, it is commonly observed that patients receiving ECMO have substantially higher sedative and analgesic drug requirements than patients without ECMO. To date, there is no ideal concept for analgesia and sedation of patients on ECMO in the ICU. A drug that sedates effectively but with minimal residual sedation after the end of the administration and without the aforementioned drawbacks of the current agents would be valuable. Interestingly, a recent randomized controlled non-inferiority trial that randomized 338 patients showed that, compared with propofol, sedation with inhaled anaesthetics was non-inferior. Sedation with inhaled anaesthetics resulted in a higher rate of spontaneous breathing and a shorter wake-up time after 48h of sedation. Indeed, inhaled sedation, which has been associated with reduced opioid consumption and less delirium in ICU patients, is a promising alternative to IV sedation. Moreover, inhaled anaesthetics might be associated with less myocardial injury and lower doses of inotropic support in patients undergoing cardiac surgery. However, to date, the experience with volatile agents remains limited in patients on ECMO. We hypothesized that the use of inhaled isoflurane with the Sedaconda anaesthetics conserving device (ACD) in cardiogenic shock patients on ECMO will reduce the mortality and increase the number of ventilation-free days at day 28 following ECMO onset compared to usual IV sedation by propofol and/or midazolam.
NCT07033065
Electrical storm (ES) is a life-threatening syndrome defined by the recurrence of ventricular arrythmias. ES is also represented by a wide spectrum of clinical situations ranging from recurrent monomorphic VT reduced by anti-tachycardia pacing (ATP) in relatively stable patients to recurrent VF in hemodynamically unstable patients. Thus, the purpose of this study was to assess the incidence and predictors of long term mortality following hospitalization in the intensive care unit for ES, in a large retrospective multicentric study.
