Vischer Annina.Vischer@usb.ch Olav Lapaire LeoErnstAlbert.Kilian@usb.ch Thilo Burkard thilo.burkard@usb.ch Predominant causes for newly diagnosed postpartum heart failure are preeclampsia and peripartum cardiomyopathy. Being an anatomical variant of Takotsubo syndrome (TTS) reverse TTS in this period is rare. We present a 36 year old patient, who had delivered triplets by cesarean section. Because of postpartum bleeding she was administered sulprostone. Later she was transferred to the Intensive Care Unit with sudden development of dyspnea, tachypnea and tachycardia. Clinical symptoms, laboratory findings and chest radiograph showed signs of acute heart failure. Transthoracic echocardiography (TTE) revealed reverse TTS with moderately reduced left ventricular ejection fraction (LVEF 39%). The patient stabilized with loop diuretic, angiotensine-converting enzyme inhibitors and beta-blockade. Breast-feeding was discouraged and bromocriptine administered. Left ventricular function normalized (LVEF 60%) within four weeks. TTS should be considered in patients with early postpartum development of heart failure. Rapid cardiac recompensation after the start of adequate therapy and complete resolution of clinical symptoms and TTE findings are typical for postpartum TTS. 2018-10-02T15:58:11+02:00 ##submission.copyrightStatement## https://www.pagepressjournals.org/index.php/cardiogen/article/view/7262 A therapeutic genome editing primer for cardiologists 2019-01-03T13:41:02+01:00 Martina Caiazza martina.caiazza@yahoo.it Daniele Masarone danielemasarone@libero.it Giuseppe Limongelli limongelligiuseppe@libero.it <p>Genome editing, or genome engineering is a type of genetic engineering in which DNA is inserted, deleted or replaced in the genome of a living organism using engineered nucleases, or <em>molecular scissors</em>. Genome editing is being rapidly adopted into all fields of biomedical research, including the cardiovascular field, where it has facilitated a greater understanding of lipid metabolism, electrophysiology, cardiomyopathies, and other cardiovascular disorders, has helped to create a wider variety of cellular and animal models, and has opened the door to a new class of therapies. In this review, we discuss the applications of <em>in vivo</em> genome-editing therapies for cardiovascular disorder.</p> 2018-05-16T11:22:47+02:00 ##submission.copyrightStatement## https://www.pagepressjournals.org/index.php/cardiogen/article/view/7127 Lamin-A/C variants found in patients with cardiac conduction disease reduce sodium currents 2019-01-03T13:41:03+01:00 Michael A.

Celestino-Soper pbcelest@iu.edu Peng-Sheng Chen chenpp@iu.edu Tomohiko Ai ait@iu.edu Matteo Vatta mvatta@iu.edu Variants in the <em>LMNA</em> gene, which encodes Lamin-A/C, have been commonly associated with cardiac conduction system diseases usually accompanying cardiomyopathy. We have seen two unrelated patients who presented with atrioventricular block (AVB) with or without cardiomyopathy. Genetic testing identified the <em>LMNA</em> missense variant c.1634G&gt;A (p.R545H) and the single nucleotide deletion c.859delG (p.A287Lfs*193). The deletion leads to a shift in the reading frame and subsequent protein truncation. Since impaired Na<sub>v</sub>1.5 function has been reported to cause AVB, we sought to investigate the effects of abnormal Lamins on Na<sub>v</sub>1.5 in HEK-293 cells using patch-clamp methods. Patch-clamp studies showed that p.R545H decreased the peak I<sub>Na</sub> by approximately 70%. The voltage-dependency of steady state inactivation was rightward shifted in the cells transfected with p.R545H. The p.A287Lfs*193 also decreased the peak I<sub>Na</sub> by approximately 62%. The voltagedependency of steady state inactivation was rightward shifted in the cells transfected with p.A287Lfs*193. Variants of the <em>LMNA</em> gene caused significant reduction of the peak I<sub>Na</sub> in HEK-293 cells, which may account for the patients’ AVB. 2018-02-22T10:52:33+01:00 ##submission.copyrightStatement## https://www.pagepressjournals.org/index.php/cardiogen/article/view/7201 Risk of sudden cardiac death in childhood hypertrophic cardiomyopathy: Time to solve the mystery 2019-01-03T13:41:03+01:00 Gabrielle Norrish g.norrish@ucl.ac.uk Juan Pablo Kaski j.kaski@ucl.ac.uk Hypertrophic cardiomyopathy (HCM) is defined as left ventricular hypertrophy in the absence of loading conditions sufficient to cause the observed abnormality. The true prevalence in childhood is unknown; the aetiology is more heterogeneous than that seen in adult populations, and includes inborn errors of metabolism, malformation syndromes and neuromuscular syndromes. However, one of the greatest clinical challenges in managing young patients with HCM is identifying those at greatest risk of sudden cardiac death. 2018-01-29T00:00:00+01:00 ##submission.copyrightStatement##
