    Abstract Coronavirus Disease 19 (COVID-19) pandemic affects the worldwide healthcare system and our understanding of this disease grows rapidly. Although COVID-19 is a mainly respiratory disease, neurological manifestations are not uncommon. The aim of this review is to report on the etiology, clinical profile, location, and outcome of patients with intracerebral hemorrhage (ICH) and COVID-19. This review includes 36 studies examining ICH in the clinical presentation of COVID-19. Overall, 217 cases with intracranial hemorrhage, of which 188 ICHs, were reported. Generally, a low incidence of both primary and secondary ICH was found in 8 studies [106 (0.25%) out of 43,137 hospitalized patients with COVID-19]. Available data showed a median age of 58 years (range: 52-68) and male sex 64%, regarding 36 and 102 patients respectively. Furthermore, 75% of the patients were on prior anticoagulation treatment, 52% had a history of arterial hypertension, and 61% were admitted in intensive care unit. Location of ICH in deep structures/basal ganglia was ascertained in only 7 cases making arterial hypertension an improbable etiopathogenetic mechanism. Mortality was calculated at 52.7%. Disease related pathophysiologic mechanisms support the hypothesis that SARS-CoV2 can cause ICH, however typical ICH risk factors such as anticoagulation treatment, or admission to ICU should also be considered as probable causes. Physicians should strongly suspect the possibility of ICH in individuals with severe COVID-19 admitted to ICU and treated with anticoagulants. It is not clear whether ICH is related directly to COVID-19 or reflects expected comorbidity and/or complications observed in severely ill patients.

    Abstract Among implantable cardioverter-defibrillator (ICD) recipients, there are patients with recurrent episodes of electrical storm (ES), retractable to the optimal antiarrhythmic drug therapy or invasive ablation procedures. A relatively novel anti-ischemic drug with also antiarrhythmic properties, ranolazine, may effectively suppress ventricular arrhythmias in such patients for a long period of time.

    Abstract Several patients receive a permanent pacemaker in a relatively young age, with multiple subsequent reoperations for pacemaker replacement. Pulse generator replacement is an invasive procedure, associated with the risk of various complications, mainly infection and skin erosion. A case of an extremely long-lasting pacemaker with a totally uneventful longevity period over 31 years is presented. The explanation for this quite rare pacemaker longevity (possibly unique) is analyzed and discussed.

    Abstract Introduction: Thrombosis of the intracardiac part of a permanent pacemaker lead, which is usually detected during a routine transthoracic echocardiographic examination, can be totally asymptomatic. The differential diagnosis between intracardiac lead thrombosis and vegetation is crucial, especially in febrile patients, as these two situations are totally different regarding prognosis and treatment.
    Case presentation: We describe the case of an 85-year-old patient with a dual chamber pacemaker (DDDR) due to complete heart block, who was admitted twice, within 2 years, with vegetation-like masses attached to the ventricular lead of the pacemaker. Infective endocarditis was not documented (diagnostic criteria were not fulfilled), although clinical suspicion was high during both hospitalizations. Masses resolved under applied treatment (anticoagulation) in both cases.
    Discussion: Differential diagnosis between lead thrombosis and vegetation was ambiguous in both hospitalizations. Τhe

    Abstract A 78-year-old man came for a scheduled check up one month after the implantation of a permanent dualchamber pacemaker for symptomatic transient atrioventricular conduction disturbances (intermittent Mobitz II atrioventricular block). The patient's ECG indicated a loss of atrial capture by the atrial electrode with 1:1 atrioventricular conduction. A subsequent X-ray examination showed that both electrodes were well placed and in their correct sites. A detailed check of the pacemaker using the programmer, together with an echocardiographic examination, revealed the true nature of the malfunction: there was a significant delay between the atrial capture and atrial depolarisation and systole, as well as a loss of ventricular capture because of an acute increase in the threshold. Normal pacemaker function and pacing ECG were restored through modification of the pacemaker's functional parameters.

    Abstract Radiofrequency ablation of Cavotricuspid Isthmus-dependent Atrial Flutter (CTI AFL), a usual and safe therapeutic procedure in interventional electrophysiology with a high success rate, aiming to induce permanent block of conduction over CTI, is normally performed via the femoral access, which allows practical access to the CTI through the inferior vena cava (IVC). In rare cases of obstruction of IVC, ablation of CTI can be performed only through the superior vena cava (SVC) access. We present a case of typical atrial flutter that was ablated through the right subclavian/jugular veins because of iatrogenic obstruction of the IVC due to a previously implanted thrombus filter. Furthermore we discuss about how we resolved access-related problems of instability during catheter ablation on CTI.
