A woman aged 64 years with cardiac sarcoidosis responded favourably to corticosteroid therapy in terms of recovered longitudinal myocardial strain, as evaluated by strain-encoded magnetic resonance imaging (SENC-MRI). In contrast, circumferential myocardial strain and late gadolinium enhancement demonstrated minimal improvement, suggesting relatively advanced pathology of the myocardial middle layer. We propose SENC-MRI as a marker of disease at an early stage of cardiac sarcoidosis.

Adaptive servo-ventilation has a potential sympathoinhibitory effect in acute cardiogenic pulmonary oedema (ACPO).

Infective endocarditis (IE) complicated by acute myocardial infarction (AMI) is frequently fatal and may require emergent interventions. However, the optimal treatment of this rare condition remains controversial as it lacks established guidelines. We successfully treated a patient with IE complicated by AMI during the acute phase using percutaneous coronary intervention (PCI) followed by surgery. A 73-year-old man was diagnosed with IE of the mitral and aortic valves caused by Streptococcus oralis. Four weeks after the initiation of antibiotics sensitive to the causative bacteria, he suddenly developed AMI manifested by chest pain and dyspnoea with cardiovascular collapse. Emergent coronary angiography revealed that the myocardial infarction was secondary to septic emboli in the left main trunk. Emergent PCI comprising aspiration and stent deployment, was successfully performed, and his vital signs were immediately stabilised. He subsequently underwent mitral and aortic valve replacement and debridement without major post-operative complications. Although the optimal treatment strategy for haemodynamically unstable AMI secondary to IE requires further discussion, the present case indicates the importance of early diagnosis and the potential effectiveness of aggressive PCI as a bridge to the following surgery.

Percutaneous Coronary Intervention for Septic Emboli in the Left Main Trunk as a Complication of Infective Endocarditis.

Maintenance of vascular integrity in the adult animal is needed for survival, and it is critically dependent on the endothelial lining, which controls barrier function, blood fluidity, and flow dynamics. However, nodal regulators that coordinate endothelial identity and function in the adult animal remain poorly characterized. Here, we show that endothelial KLF2 and KLF4 control a large segment of the endothelial transcriptome, thereby affecting virtually all key endothelial functions. Inducible endothelial-specific deletion of Klf2 and/or Klf4 reveals that a single allele of either gene is sufficient for survival, but absence of both (EC-DKO) results in acute death from myocardial infarction, heart failure, and stroke. EC-DKO animals exhibit profound compromise in vascular integrity and profound dysregulation of the coagulation system. Collectively, these studies establish an absolute requirement for KLF2/4 for maintenance of endothelial and vascular integrity in the adult animal.
