Heart beats: not to be beaten

of a brain stem infarction as a complication of percutaneous coronary intervention. Within the electrophysiology theme, De Roeck et al. [6] discuss retrograde access of the left atrium for pulmonary vein isolation using magnetic navigation after closure of an atrial septal defect. This approach proved to provide a feasible, safe and successful alternative for catheter ablation of cardiac arrhythmias in patients in whom the classic trans-septal approach is impossible. Ram-djan et al. [7] report successful endovascular catheter abla-tion of ventricular tachycardia in a patient with a surgically repaired congenital left ventricular aneurysm. Within the topic of electrophysiology, we have also published two Letters to the Editor in a response-and-answer format. Kumar et al. [8] comment on the first Dutch experience with the second-generation endoscopic laser balloon ablation system for the atrial fibrillation published by Gal et al. [9] in a previous issue of NHJ. This comment was responded by Gal and Elvan [10]. Within the subject of congenital heart disease, Alse-mgeest et al. [11] describe the first patient with a rapidly progressive dilated cardiomyopathy caused by an atypical aortic coarctation with a rapid normalisation of ventricular function after treatment by stenting. Pans et al. [12] evaluate the haemodynamics in a patient with Fontan physiology undergoing laparoscopic cholecystectomy. Laparoscopic surgery showed advantages over open surgery: less post-operative pain, shorter hospital stay, a reduction in post-operative wound infections and a reduction of respiratory complications. Within the topic of cardiac surgery, van Houte et al. [13] report on the use of percutaneous femoral veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in a fully awake, non-intubated and spontaneously breathing patient suffering from acute, severe and refractory cardio-genic shock due to a (sub)acute anterior myocardial infarc-The summer 2015 issue of the Netherlands Heart Journal (NHJ) deviates from the regular NHJ issues. Following the usual Editor's Comment [1], the July/August 2015 issue starts with a review article on cardiovascular genetics by Asselbergs et al. [2]. In this review, the genetic variants, mutations and inheritance models are briefly introduced, after which an overview is provided of current clinical and technological applications in gene diagnostics and research for cardiovascular disease and in particular, dilated cardio-myopathy. Following this very elucidating review article, the present issue is almost entirely dedicated to Heart Beats, a category that was initiated last year in our journal to replace the Case Reports and Images [3]. Heart Beats offer more concise and succinct information than case reports …
