    Abstract Background: Acute myocardial infarction (AMI) and acute ischemic stroke (AIS) are the leading causes of death globally. Cardio-cerebral infarction (CCI) is the rare occurrence of AMI and AIS, either simultaneously or one after the other. Treatment recommendations are not clear in case of the occurrence of AMI and AIS simultaneously, especially the strategy of primary percutaneous coronary intervention (PCI).
    Case presentation: We report consecutive seven case series of patients with CCI who underwent primary PCI in our institute. Comorbidities, strategy of primary PCI, and outcomes were investigated. All patients presented with the chief complaints associated with stroke. Atrial fibrillation (AF) was complicated in five of CCI patients, and four of AF patients were not anticoagulated. The major causes of stroke were cardiogenic and/or hemodynamic in this case series. All patients showed total occlusion in the culprit lesion, and six patients had other diseased vessels. Thrombus aspiration was mainly chosen as the reperfusion strategy in PCI. However, only two patients were diagnosed as definitive coronary embolism, and stenting was needed in six patients due to severe atherosclerotic lesion in culprit coronary artery. Final thrombolysis in myocardial infarction (TIMI) 3 flow was achieved only in four patients. Hemorrhagic complications occurred in three patients. Two patients died during in-hospital stay, and most had to be transferred for rehabilitation.
    Conclusions: CCI was a rare but fatal condition in patients who underwent primary PCI. Although CCI was associated with concomitant atrial fibrillation, organic coronary stenosis requiring stenting for revascularization was present in almost all the cases. Given the complexity of coronary artery lesions and high in-hospital mortality, further investigations are needed to determine the optimal treatment strategy.

    Abstract Background: Thrombus aspiration (TA) has been considered a procedure for controlling distal emboli and improving microvascular perfusion. However, current guidelines classify routine TA as class III recommendation, and it has been reported that the efficacy of TA is limited because of the relatively high incidence of failure in retrieval of thrombotic material. The aim of this study was to explore patient characteristics and procedural factors associated with successful TA in ST-elevation myocardial infarction (STEMI) and to assess the clinical impact of successful TA.
    Methods: This single-center retrospective study enrolled 158 STEMI patients who underwent TA as initial recanalization. Factors associated with successful TA, which was defined as retrieving any visible material by aspiration catheter, were explored, and angiographical and short-term outcomes were assessed.
    Results: In 146 cases (92.4%), the aspiration catheter reached the culprit lesion. Successful TA was achieved in 72 cases (45.6%). The single angiographical characteristic of successful TA was a higher Thrombolysis in Myocardial Infarction grade before TA. Among the procedural characteristics, the rate of successful TA was higher with a 7-French aspiration catheter compared with the rate with a 6-French catheter (57.1% vs. 29.9%, P  = 0.01). Thrombolysis in Myocardial Infarction grade 3 flow was more frequent in patients with successful TA immediately after TA (36.1% vs. 16.3%, P  = 0.006) and at final angiography (91.7% vs 79.1%, P  = 0.04) compared with the grade in patients without successful TA, respectively.
    Conclusions: The use of a larger aspiration catheter may be effective in retrieving visible thrombus material, and successful TA led to better angiographical results.

    Abstract Herein, we report a case of 61-year-old male with congestive heart failure (HF) due to severe aortic regurgitation (AR) caused by ruptured aortic valve aneurysm (VA). Aortic valve replacement (AVR) was performed after improvement of HF symptoms. Pathological examination of resected aortic VA showed neutrophil infiltration. Although he did not have typical clinical features associated with infective endocarditis (IE) such as fever, leukocytosis, or positive blood culture, we misdiagnosed this case as "concealed IE". However, we reconsidered the etiology because prosthetic aortic valve detachment occurred only one year after AVR. When considering causes except IE for perforated aortic VA and early prosthetic valve detachment, Behçet's disease (BD) was more likely based on the clinical course, echocardiography, and pathological findings in this case. The inflammatory process of BD is associated with aortic valvulitis/aortitis, leading to a possible cause of aortic regurgitation due to aortic VA or early prosthetic valve detachment. The diagnosis of BD was challenging in this case because he did not have predominant clinical findings, including recurrent oral ulcer which is a mandatory criterion for the diagnosis by the International Study Group, however, cardiac involvement may have been the initial presentation of BD. <
