Neuro-arrhythmology: a challenging field of action and research: a review from the Task Force of Neuro-arrhythmology of Italian Association of Arrhythmias and Cardiac Pacing There is a growing interest in the study of the mechanisms of heart and brain interactions with the aim to improve the management of high-impact cardiac rhythm disorders, first of all atrial fibrillation. However, there are several topics to which the scientific interests of cardiologists and neurologists converge constituting the basis for enhancing the development of neuro-arrhythmology. This multidisciplinary field should cover a wide spectrum of diseases, even beyond the classical framework corresponding to stroke and atrial fibrillation and include the complex issues of seizures as well as loss of consciousness and syncope. The implications of a more focused interaction between neurologists and cardiologists in the field of neuro-arrhythmology should include in perspective the institution of research networks specifically devoted to investigate ‘from bench to bedside’ the complex pathophysiological links of the abovementioned diseases, with involvement of scientists in the field of biochemistry, genetics, molecular medicine, physiology, pathology and bioengineering. An investment in the field could have important implications in the perspectives of a more personalized approach to patients and diseases, in the context of ‘precision’medicine. Large datasets and electronic medical records, with the approach typical of ‘big data’ could enhance the possibility of new findings with potentially important clinical implications. Finally, the interaction between neurologists and cardiologists involved in arrythmia management should have some organizational implications, with new models of healthcare delivery based on multidisciplinary assistance, similarly to that applied in the case of syncope units.

An unusual case of iatrogenic Twiddler's syndrome Twiddler's syndrome is an uncommon cause of cardiac implantable electronic device malfunction, usually due to manipulation of the pulse generator. A few spontaneous cases have already been described. We present the unique case of a 77-year-old woman who experienced iatrogenic Twiddler's syndrome.

A 10-year follow-up of a patient affected by myotonic dystrophy type 1 with implantable cardioverter–defibrillator implanted for secondary prevention Cardiac involvement in myotonic dystrophy type 1 (DM1) is frequent with an increased incidence of conduction disturbances and sudden cardiac death when compared with the general population. We described the case of a young man in whom the diagnosis of DM1 was made 8 years after the occurrence of cardiac arrest (CA) owing to ventricular fibrillation and ICD was implanted 4 years later (12 years after CA). During the subsequent 10 years, despite the deterioration of neuromuscular conditions, no appropriate or inappropriate shocks occurred.

Looking for the right way: right coronary artery originating from a left anterior descending acutely occluded just distally to the bifurcation We describe the case of a patient referred to our cathlab due to anterior ST segment elevation myocardial infarction. Through the right radial artery route, after multiple attempts to cannulate the right coronary artery (RCA), we proceeded to left coronary angiography, which showed an abnormal origin of RCA from the middle segment of the left anterior descending (LAD), that was occluded just distally to the bifurcation. We performed a primary angioplasty of the LAD throughout a direct stent implantation, with a good angiographical result and the evidence of a myocardial bridging below the implanted stent. The patient was discharged, asymptomatic, after 7 days.

Mechanical atrial recovery after cardioversion in persistent atrial fibrillation evaluated by bidimensional speckle tracking echocardiography Background Atrial fibrillation induces reversible electrical and mechanical modifications (atrial remodeling). Atrial stunning is a mechanical dysfunction with preserved bioelectrical function, occurring after successful atrial fibrillation electrical cardioversion (ECV). Two-dimensional speckle tracking echocardiography is a new technology for evaluating atrial mechanical function. We assessed atrial mechanical function after ECV with serial two-dimensional speckle tracking echocardiography evaluations. The investigated outcome was left atrium mechanical recovery within 3 months. Methods A total of 36 patients [mean age 73 (7.9) years, 23 males] with persistent atrial fibrillation underwent conventional transthoracic and transesophageal echocardiography before ECV. Positive global atrial strain (GSA+) was assessed at 3 h, 1, 2, 3, 4 weeks and 3 months after ECV. Mechanical recovery was defined as the achievement of a GSA+ value of 21%. Results Independent predictors of GSA+ immediately after ECV (basal GSA+) were E/e′ ratio and left atrial appendage anterograde flow velocity. During the follow-up, 25% of patients suffered atrial fibrillation recurrence. In 12/36 patients (33%) left atrium mechanical recovery was detected (mechanical recovery group), while in 15/36 (42%) recovery did not occur (no atrial mechanical recovery group). At univariate analysis, the variables associated with recovery, were basal GSA+ (P = 0.015) and maximal velocity left atrial appendage (P = 0.022). Female sex (P = 0.038), N-terminal pro-B type natriuretic peptide (P = 0.013), E/e′ (P = 0.042) and the indexed left atrium volume (P = 0.019) were associated with the lack of left atrium mechanical recovery. Conclusion In almost half of the patients, the left atrium did not resume mechanical activity within the 3 months after ECV, despite sinus rhythm recovery. The left atrium of these patients was larger, stiffer and their E/E′ was higher, suggesting a higher endocavitary pressure compared with mechanical recovery patients. These findings might suggest an increased thromboembolic risk.

When the bundle skips a beat… Intermittent bundle branch block is generally a functional phenomenon because of heart rate variation. It commonly depends by a dependent tachycardia or bradycardia bundle branch block. A rare alternative cause is the Wenckebach phenomenon in bundle branch. We show a singular case of concealed 3:2 Wenckebach phenomenon in the right bundle branch.

Midventricular Takotsubo cardiomyopathy complicated by a ventricular septal rupture: a surgical management Takotsubo cardiomyopathy, also known as ‘Broken Heart Syndrome’, is a form of acute heart failure, featured by a reversible impairment in cardiac contractility. About 20% of patients during hospitalization experience complications including cardiogenic shock, stroke, left ventricular thrombosis or death. Ventricular rupture has already been reported in Takotsubo cardiomyopathy in patients with typical apical ballooning pattern. We report one of the first cases of a midventricular ballooning Takotsubo cardiomyopathy in a 57-year-old woman complicated by ventricular septal rupture, successfully repaired with a surgical interrupted suture technique.

Aortic valve-in-valve implantation requiring valve fracturing via a subclavian access: new insights with a word of caution The valve-in-valve treatment of small aortic bioprostheses is still matter of debate. In this setting, high-pressure balloon fracturing may represent an option to treat patients with a previously implanted small biological heart valve in order to improve the transvalvular gradient and to reduce the risk of patient-prosthesis mismatch. The feasibility of this approach was recently demonstrated but long-term resutls of large series are not available. We here report a trans-subclavian access for this procedure. However, after successful implantation and uneventful discharge, the patient suffered from sudden cardiac death.
