The following case is the first published endovascular treatment of synchronous heart and brain infarctions delivered by a single operator with excellent clinical outcome. CASE SUMMARY: A 67-year-old female patient was directly transported to the emergency room of a comprehensive stroke centre with acute onset global aphasia and right hemiplegia. The onset to admission time exceeded the 4.5-h time window of systemic thrombolysis. Head computed tomography (CT) excluded extensive early extensive brain damage, CT angiography documented left middle cerebral artery occlusion and mechanical thrombectomy was indicated. Extensive anterior ST elevation was detected on the transport monitor while waiting for in-hospital transfer. The two simultaneously evolving pathologies were handled in a single endovascular procedure that took less than 60 min by a dual-trained interventional cardiologist/neurointerventional surgeon. The patient recovered without any major cardiac or neurologic sequela. DISCUSSION: Interventional cardiologists, professionally trained through a neurointerventional fellowship programme to perform endovascular stroke interventions according to the latest multi-society position paper, could not only complement stroke teams lacking manpower, but their unique experience could also help the patients suffering from the most devastating forms of cardio-cerebral infarctions. The successful parallel management of myocardial and cerebral infarctions is a challenging task. A series of difficult and timely decisions must be taken to avoid the potential devastating thrombotic and haemorrhagic complications related to the two simultaneously evolving pathologies. While the acute treatment algorithm of the two distinct diseases is well-guided by the evidence-based literature, 2,3 no clear guidelines are available on the rare co-occurrence of the two emergencies. Due to the narrow therapeutic time window and lifethreatening natural course of diseases, the mortality rate associated with the cardio-cerebral infarctions is extremely high according to the published case series. 4, 5 The successfully treated cases may represent a useful learning reference to guide the decision-making in these difficult scenarios. Interventional cardiologists completing the neurointerventional training programme outlined in the latest multi-society consensus document 1 are ideally fit for performing such difficult interventions, as demonstrated by the outcome of the following clinical case. A 67-year-old female patient with no previous history of chronic disease was found lying on the ground unresponsive, 3 h after being 'last seen well' by her family members. She got directly transported to the nearest comprehensive stroke centre with onsite endovascular treatment capability. The on-call neurologist documented global aphasia, left conjugate gaze deviation, right facial palsy, and right hemiplegia [National Institute of Health Stroke Scale (NIHSS) of 21]. Native computed tomography (CT) scan ruled out haemorrhage and showed no early ischaemic changes in the left hemisphere ( Figure 1A) . Artificial intelligence-based image analysis (Brainomix, Oxford, UK) measured an Alberta Stroke Program Early CT Score of 10/10, signifying no early ischaemic damage of the brain tissue. 6 Computed tomography angiography analysis revealed the occlusion of the left middle cerebral artery (MCA) main segment ( Figure 1B) . 12:00 Patient found down, alert but unresponsive, unable to move the right side. Direct ambulance transfer to the comprehensive stroke centre. • Aphasic patients suffering from brain infarctions may be unable to express their pain even in case of concomitant ST-elevation myocardial infarction. This fact underlies the importance of routine 12-lead electrocardiogram recording during the admission of every stroke patient. • The successful parallel management of acute cerebral and myocardial infarctions is depended on time and finding the optimal balance between thrombotic and haemorrhagic risk factors. • Interventional cardiologists, who complete a formal neuro interventional training may contribute substantially to endovascular stroke teams by applying their unique expertise. As the exact onset of symptoms was unknown, the neurologist decided to withhold IV thrombolysis and send the patient directly to mechanical thrombectomy. The ER staff spotted a large ST elevation on the monitor of the patient waiting for transfer to the angiography suite. While the patient could not signal chest pain, being completely mute due to aphasia, a 12-lead electrocardiogram (ECG) confirmed the extensive anterior ST-elevation myocardial infarction (STEMI) pattern (Figure 2A) . The neurointerventional service that day was provided by an accredited interventional cardiologist with completed neurointerventional fellowship training, thus a consensual decision was taken by the cardiology and neurology teams to request the execution of the necessary endovascular interventions within a single procedure. The patient was transferred to the catheterization laboratory with anaesthesia backup. The right femoral artery was cannulated with an oversized, 9-Fr sheath to allow continuous invasive blood pressure Figure 3A) . Taken the slow but persistent coronary flow, the patient's stable haemodynamic condition, and the haemorrhagic risk associated with a stroke intervention under dual antiplatelet therapy into account, coronary stenting was temporarily withheld, and 500 mg of IV aspirin was administered only (Figure 4) . To save time, the fastest cerebral recanalization technique, aspiration thrombectomy was performed in the left MCA using a dedicated 6-Fr aspiration catheter (Sofia Plus, Microvention Terumo Inc., Aliso Viejo, CA, USA). Complete flow restoration was achieved with a single pass, and the patient's right hemiplegia promptly improved. As no sign of complication was detected on control angiography ( Figure 3B and C) , the operator decided to continue with the coronary revascularization after the administration of 7500 IU Na-heparin. Two 14 00 guidewires were advanced into the LAD and circumflex Figure 3D) . Although the origin of the CX was covered with struts, the flow was patent, and no further post-dilatation was performed to avoid the need for bifurcation stenting. The puncture site was closed by a closure device. As soon as the post-operative control CT ruled out any complication ( Figure 5B) , the patient was loaded with 600 mg of clopidogrel. Control ECG in the cardiac care unit showed complete ST resolution ( Figure 5A) . Neurological examination on the following day revealed only mild clumsiness of the right hand with a very mild word-finding difficulty (NIHSS 2 points). Laboratory analysis documented a peak high-sensitivity troponin T level of 595 pg/mL. Cardiac magnetic resonance imaging performed on the 12th day following the interventions showed preserved ejection fraction (EF 55%) with only mild septal hypokinesia. Surprisingly, no late enhancement and no cardiac source of emboli were documented ( Figure 5C ). Prolonged rhythm monitoring using 72-h Holter ECG did not detect atrial fibrillation. Patient was scheduled for haematology examination as the next step of her work up. She remained independent upon her discharge to rehabilitation (modified Rankin Scale: 1). The simultaneous occurrence of cardio-cerebral infarction is a rare clinical entity with a prevalence rate of about 0.25% among the patients admitted for acute myocardial or cerebral infarctions, based on the largest institutional series. 5 The optimal clinical management of these patients is poorly defined, and the overall mortality was found to be larger than 45% at 30 days applying medical therapy or consecutive endovascular interventions provided by separate teams, even though various sequences of the reperfusion therapy (brainheart vs. heart-brain) were used in these cases. 5 The rapid revascularization of the infarcted territories in the two organs is elementary to avoid death and permanent disability (Figure 4) . The optimal timing of the various components of the anti-thrombotic therapy is also critical, as the obligatory use of antiplatelet medications and anticoagulants in STEMI management can significantly increase the risk for haemorrhagic complications in ischaemic stroke, especially if the blood-brain barrier is compromised by prolonged cerebral ischaemia or by an otherwise minor vascular injury associated with the mechanical recanalization. 7 Interventional cardiologist formally trained to perform endovascular treatment (EVT) in stroke according to the position paper of European Society of Cardiology Council on Stroke 4 are theoretically ideally placed to handle cardio-cerebral infarctions. Based on the results of early feasibility studies, properly trained interventional cardiologists working as part of a multidisciplinary stroke team demonstrated similar patient outcomes in the endovascular management of ischaemic stroke as neurointerventional specialists with neurosurgical or radiological training background, 8, 9 while the above presented case suggest, that in cardio-cerebral infarction the dual-trained cardiologists may even outperform other specialists of the field. The rapid execution of simple interventional solutions and the careful stepwise administration of the various components of anti-thrombotic therapy have all largely contributed to the final good outcome of our case. We do acknowledge, however, that the successful management of such a complex clinical situation is dependent on multiple factors, including many that are not controllable by the care providers. In conclusion, the adequate treatment of cardio-cerebral infarctions requires the rapid but careful evaluation of multiple disease aspects, and even if the interventions are performed by a single operator, the ultimate good outcome can only be reached through multidisciplinary cooperation and the functional integration of the acute care networks.
