ABSTRACT

Background: In patients with cardiogenic shock the clinical treatment often involves temporary mechanical circulatory support for initial haemodynamic stabilization to enable further assessment of therapeutic strategies. The surgically implanted Impella 5.5 can be used for several indications like ventricular unloading, haemodynamic support during high-risk interventions, and as a bridge-to-transplant strategy.We present an interdisciplinary managed case of using Impella 5.5 for multiple indications and treatment strategies in one patient. Case summary: A 66-year-old patient with known dilated cardiomyopathy was admitted with non-ST-elevation myocardial infarction and underwent urgent coronary bypass grafting. His native heart function did not recover and he experienced recurrent episodes of sustained ventricular tachycardia (VT) and electrical storm. He was evaluated for heart transplantation (OHT) and received a VT-ablation. However, he suffered an in-hospital cardiac arrest (IHCA) with subsequent implantation of an extracorporeal life support system (ECLS). After surgical placement of an Impella 5.5 due to left ventricular distension and pulmonary congestion, the ECLS was successfully weaned. He showed good neurological outcomes and underwent another high-risk VT-ablation. The patient was further stabilized under Impella 5.5 support in a bridge-to-transplant strategy. After 34 days he underwent a successful OHT. Discussion: In this interdisciplinary case report the surgically implanted Impella 5.5 as temporary mechanical circulatory support was used for multiple different indications and treatment strategies like ventricular unloading, haemodynamic support during high-risk interventions, and as bridge-to-transplant strategy in one patient.

ABSTRACT

BACKGROUND: Individualization and patient-specific optimization of treatment is a major goal of modern health care. One way to achieve this goal is the application of high-resolution diagnostics together with the application of targeted therapies. However, the rising number of different treatment modalities also induces new challenges: Whereas randomized clinical trials focus on proving average treatment effects in specific groups of patients, direct conclusions at the individual patient level are problematic. Thus, the identification of the best patient-specific treatment options remains an open question. Systems medicine, specifically mechanistic mathematical models, can substantially support individual treatment optimization. In addition to providing a better general understanding of disease mechanisms and treatment effects, these models allow for an identification of patient-specific parameterizations and, therefore, provide individualized predictions for the effect of different treatment modalities. RESULTS: In the following we describe a software framework that facilitates the integration of mathematical models and computer simulations into routine clinical processes to support decision-making. This is achieved by combining standard data management and data exploration tools, with the generation and visualization of mathematical model predictions for treatment options at an individual patient level. CONCLUSIONS: By integrating model results in an audit trail compatible manner into established clinical workflows, our framework has the potential to foster the use of systems-medical approaches in clinical practice. We illustrate the framework application by two use cases from the field of haematological oncology.
