Transition to heart transplantation in post-myocardial infarction ventricular septal rupture: a systematic review

Post-myocardial infarction ventricular septal rupture (MI-VSR) remains a dreadful complication with dismal prognosis. Surgical repair is the primary treatment strategy, whereas the role of heart transplantation (HT) as a primary option in MI-VSR is limited to case reports (CRs). We performed a systematic review of CRs to describe in-hospital mortality, and survival at 6 and 12 months in adult patients with MI-VSR treated with HT as a primary or bailout strategy. We performed a comprehensive search of Web of Science, PubMed, and Ovid Medline. The last search was completed on March 10, 2020. An aggregated score based on the CARE case report guideline was used to assess the quality of the CRs. We included CRs that described adult patients with MI-VSR treated with HT as a primary or bailout strategy. A total of 14 CRs between 1994 and 2015 were included, retrieving and analyzing the characteristics of 17 patients. A total of 12 patients underwent HT, with HT being the primary strategy in 8 patients and a bailout strategy for 4 patients following initial surgical repair, while 5 patients died awaiting HT under mechanical circulatory support (MCS), accounting for the total in-hospital mortality of this series (29%). Regarding long-term outcomes, 6 patients were reported to be alive at 6 months and 1 year after HT, while information was missing in the remaining 6 patients. In conclusion, HT supported by the use of temporary and durable MCS as a bridge to HT could be a feasible primary or bailout strategy to reduce the high in-hospital mortality of patients with MI-VSR.

2019 EACTS Expert Consensus on long-term mechanical circulatory support

Long-term mechanical circulatory support (LT-MCS) is an important treatment modality for patients with severe heart failure. Different devices are available, and many-sometimes contradictory-observations regarding patient selection, surgical techniques, perioperative management and follow-up have been published. With the growing expertise in this field, the European Association for Cardio-Thoracic Surgery (EACTS) recognized a need for a structured multidisciplinary consensus about the approach to patients with LT-MCS. However, the evidence published so far is insufficient to allow for generation of meaningful guidelines complying with EACTS requirements. Instead, the EACTS presents an expert opinion in the LT-MCS field. This expert opinion addresses patient evaluation and preoperative optimization as well as management of cardiac and non-cardiac comorbidities. Further, extensive operative implantation techniques are summarized and evaluated by leading experts, depending on both patient characteristics and device selection. The faculty recognized that postoperative management is multidisciplinary and includes aspects of intensive care unit stay, rehabilitation, ambulatory care, myocardial recovery and end-of-life care and mirrored this fact in this paper. Additionally, the opinions of experts on diagnosis and management of adverse events including bleeding, cerebrovascular accidents and device malfunction are presented. In this expert consensus, the evidence for the complete management from patient selection to end-of-life care is carefully reviewed with the aim of guiding clinicians in optimizing management of patients considered for or supported by an LT-MCS device.
