Septal rupture closure: Still a challenge

Key Points Review of the Medicare database shows that over the past 16  years the incidence of post‐ myocardial infarction (MI) ventricular septal rupture (VSR) has decreased but mortality for all post‐MI VSR hospitalizations remains unchanged and high During the study period, the 30‐day VSR repair rate decreased from 49.9% in 1999 to 33.3% in 2014. Unadjusted mortality was lower for patients undergoing repair procedures than for those not undergoing repair both at 30 days and at 1‐year. Most VSR patients underwent surgical repair (82.9%) and only a minority underwent transcatheter repair (17.1%). Regardless of the approach, outcomes remain unsatisfac tory.

As this article notes, researchers have recently suggested that the benefits to heart function observed over many years of stem cell therapies are not in fact due to any action of the cells themselves, not even cell signaling mechanisms such as release of exosomes, but are rather due to an immune response to the transplanted cells. The study reported here illustrates the point by showing some degree of regeneration of injured heart tissue to take place in mice when the debris of dead cells is transplanted. We might compare these findings with the body of work showing that delivery of exosomes can spur cardiac regeneration;...

Abstract In humans, loss of central tolerance for the cardiac self-antigen, α-myosin heavy chain (αMyHC), leads to circulation of cardiac autoreactive T cells and renders the heart susceptible to autoimmune attack after acute myocardial infarction (MI). MI triggers profound tissue damage, releasing danger signals and self-antigen by necrotic cardiomyocytes, which leads to recruitment of inflammatory monocytes. We hypothesized that excessive inflammation by monocytes contribute to the initiation of adaptive immune responses to cardiac self-antigen. Using an experimental model of MI in mice, αMHC-m...

Abstract Ventricular free wall rupture is a fatal mechanical complication of acute myocardial infarction. In some cases it can be represented as subacute clinic and may not cause death in a few minutes. Acute pseudo-aneurysms are extremely unstable and bound to fatal rupture. Herein we report a male patient who suffered dyspnea and mild chest pain, 4 weeks after acute ST-segment elevation myocardial infarction.

Authors: Bai M, Pan CL, Jiang GX, Zhang YM, Zhang Z Abstract OBJECTIVE: The aim of this study was to investigate the effects of butylphthalide on oxidative stress and inflammatory response in rats with myocardial infarction through the protein kinase B/nuclear factor E2-related factor 2 (Akt/Nrf2) signaling pathway. MATERIALS AND METHODS: A total of 36 Sprague-Dawley rats were randomly divided into three groups, including sham group (n=12), model group (n=12) and butylphthalide group (n=12). In the sham group, the heart was exposed, and normal saline was intraperitoneally injected after the operation. In the mo...

ConclusionCombined endovascular aneurysm repair and on-pump beating heart coronary artery bypass grafting in a one-stage operation is a promising strategy to improve therapeutic efficiency in octogenarians. More studies are needed to compare the efficacy and safety of one-stage and two-stage operations to treat concomitant coronary artery disease and aortovascular pathology in the high-risk octogenarian patients.

Gabriels, Allard C. van der WalAbstractBackgroundCoronary thrombosis is a process with unpredictable clinical outcome. Changes of thrombus composition overtime influence tissue repair and stabilization. We investigated rates of cell deaths and cell proliferation at different time points after initiation of thrombosis.MethodsThrombectomy aspirates of 55 myocardial infarction patients were selected and histomorphologically classified as fresh (25), lytic (25), partially fibrocellul...

r DYR Abstract Defective coronary network function and insufficient blood supply are both cause and consequence of myocardial infarction. Efficient revascularization after infarction is essential to support tissue repair and function. Zebrafish hearts exhibit a remarkable ability to regenerate, and coronary revascularization initiates within hours of injury, but how this process is regulated remains unknown. Here, we show that revascularization requires a coordinated multi-tissue response culminating with the formation of a complex vascular network available as a scaffold for cardiomyocyte repopulation. During a p...

CONCLUSIONS: LOSC seems to be safe and effective procedure when preformed in elective manner. On the other side, urgent LOSC after EVAR is associated with very high postoperative mortality and morbidity. Endoleak remains the main indication for open conversion. Further studies are necessary to standardize timing and treatment options for failing EVAR. PMID: 31755677 [PubMed - as supplied by publisher]
