Macrophage Transitions in Heart Valve Development and Myxomatous Valve Disease.

CONCLUSIONS: Our study demonstrates the heterogeneity of myeloid cells in heart valves and highlights an alteration of macrophage subpopulations, notably an increased presence of infiltrating CCR2+ monocytes and CD206+ macrophages, in myxomatous valve disease.

CONCLUSIONS: The current study identified preoperative characteristics associated with an increased risk of reintervention. No preoperative characteristics had any significant interactions with EVT or surgical reconstruction. PMID: 32224557 [PubMed - as supplied by publisher]

Pulmonary endarterectomy (PEA) is a curative surgical option for patients with chronic thromboembolic pulmonary hypertension (CTEPH), a disease resulting from chronic pulmonary thromboembolism. The role of sarcopenia (i.e. low skeletal muscle mass) has been shown to be associated with adverse outcomes in surgical populations, but its significance with PEA remains unknown. We sought to evaluate the association of sarcopenia with measures of CTEPH severity and post-operative hospital outcomes.

We present six cases of outflow graft obstruction (OGO) other than twist of the outflow graft under oral anticoagulation.

Bleeding complications during left ventricular assist device (LVAD) support pose anticoagulation challenges as risk of discontinuation of anticoagulation, even in the setting of bleeding, may pose an increased risk of subsequent LVAD hemolysis or thrombosis. We assessed whether discontinuation of anticoagulation in HM3 patients whose bleeding concerns preventing anticoagulation would adversely impact outcomes.

n F Abstract Aortic valve stenosis is the most prevalent heart valve disease worldwide. Although interventional treatment options have rapidly improved in recent years, symptomatic aortic valve stenosis is still associated with high morbidity and mortality. Calcific aortic valve stenosis is characterized by a progressive fibro-calcific remodeling and thickening of the aortic valve cusps, which subsequently leads to valve obstruction. The underlying pathophysiology is complex and involves endothelial dysfunction, immune cell infiltration, myofibroblastic and osteoblastic differentiation, and, subsequently, calcific...

CONCLUSIONS: The findings imply that endothelial FSTL1 is critical for the homeostasis of vascular walls, and its insufficiency may favor cardiovascular fibrosis leading to heart failure. PMID: 32078339 [PubMed - as supplied by publisher]

CONCLUSIONS: These results establish retinoid regulation of human cardiovascular calcification, provide new insight into mechanisms involved in these responses, and suggest selective retinoid modulators, like acyclic retinoids may allow for treating cardiovascular calcification without the adverse effects associated with cyclic retinoids.

CONCLUSIONS: This study identifies one of the underlying molecular mechanisms of heart valve calcification and demonstrates that overexpression of Cad-11 upregulates RhoA and Sox9 to induce calcification and extracellular matrix remodeling in adult AoV pathogenesis. The findings provide a potential molecular target for clinical treatment. PMID: 27312222 [PubMed - as supplied by publisher]
