BACKGROUND: Little is known about the suitability of implantable cardioverter defibrillator (ICD) implantation in patients with cardiac sarcoidosis (CS). We evaluated the efficacy of ICD implantation in patients with CS, including suspected CS, compared with those with idiopathic dilated cardiomyopathy (DCM). METHODS: A total of 102 consecutive patients with definite CS, suspected CS, or DCM who underwent ICD implantation were enrolled. The endpoint was the first documentation of appropriate ICD therapy for ventricular tachyarrhythmias...

BACKGROUND: One approach to improve ablation for atrial fibrillation (AF) is to focus on physiological targets including focal or rotational sources or ganglionic plexi (GP). However, the spatial relationship between these potential mechanisms has never been studied. We tested the hypothesis that rotors and focal sources for AF may co-localize with ganglionated plexi (GP). METHODS: We prospectively identified locations of AF rotors and focal sources, and correlated these to GP sites in 97 consecutive patients (age 59...

BACKGROUND: Long QT Syndrome type 2 (LQT2) is caused by mutations in the KCNH2 gene that encodes for the α-subunit (hERG) of the ion channel conducting the rapid delayed rectifier potassium current (IKr). We have previously identified a disease causing mutation (IVS9-28A/G) in the branch point of the splicing of KCNH2 intron 9. However, the mechanism through which this mutation causes the disease is unknown. METHODS AND RESULTS: We generated human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) from fibroblasts of two IVS9-28A/G mutation carriers...

BACKGROUND: The aim was to describe temporal trends in admission rates for chest pain and patient outcomes after the clinical introduction of the high-sensitivity cardiac troponin T (hs-cTnT) assay. METHODS: We included all patients aged >25years presenting with chest pain to the emergency department (ED) at our hospital during 2011-2014. For each year, rates of admissions, coronary angiographies, and revascularizations were determined. After adjustment for confounders, hazard ratios (HR) with 95% confidence intervals (CI) were calculated for mortality or major adverse cardiac events (MACE) within 1year of the ED visit per year, using 2011 as referent...

BACKGROUND: Adaptive cardiac resynchronization therapy (aCRT) is a dynamic optimization algorithm which paces only the left ventricle (LV) when atrio-ventricular (AV) conduction is normal, thus reducing right ventricular (RV) pacing. However, the impact of QRS duration on aCRT efficacy remains uncertain. We examined whether QRS duration impacts aCRT effectiveness in patients with left bundle branch block (LBBB) and preserved AV conduction. METHODS: Randomized patients in the Adaptive CRT trial, which enrolled NYHA III/IV patients, were used in this analysis...

BACKGROUND: Transesophageal echocardiography (TEE) is routinely performed before atrial fibrillation (AF) transcatheter ablation to exclude the presence of left atrial (LA) or LA appendage (LAA) thrombi. The aim of the study is to evaluate if easily accessible clinical parameters may relate to the presence of LA or LAA thrombi to identify patients who could potentially avoid TEE. METHODS AND RESULTS: Between January 2012 and September 2014, data from 1539 consecutive patients undergoing TEE, as a work-up before AF transcatheter ablation, in six large volume centers were collected...

AIM: Metalloproteinases inhibition by doxycycline reduces cardiac protein degradation at extracellular and intracellular level in the experimental model ischemia/reperfusion injury. Since both extracellular cardiac matrix and titin filaments inside the cardiomyocyte are responsible for the myocardial stiffness, we hypothesized that doxycycline could favorably act on left ventricular (LV) filling pressures in patients after reperfused acute ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: Seventy-three of 110 patients of the TIPTOP trial underwent a 2D-Echo-Doppler on admission, and at pre-discharge and at 6-month after a primary PCI for STEMI and LV dysfunction...

BACKGROUND: Systemic administrations of conventional antithrombotics reduce neointima formation after angioplasty in experimental animals. However, clinical translation of these results has not been successful due to high risk for bleeding. OBJECTIVES: We sought to determine whether novel annexin-V (ANV)-Kunitz protease inhibitor fusion proteins, TAP-ANV and ANV-6L15, can specifically target to vascular injury site and limit neointima formation without inducing systemic hypo-coagulation in a rat carotid artery balloon angioplasty injury model...

BACKGROUND: Adverse drug events (ADEs) with pulmonary vasodilator use in pulmonary arterial hypertension (PAH) are common. ADEs may contribute to worse quality of life; however, their relationship to prognosis is unknown. The objective of this study was to determine whether common ADEs after initiating subcutaneous treprostinil were associated with prognosis in PAH. METHODS: We assembled a retrospective cohort of participants from four clinical trials of treprostinil for PAH, including 908 participants who received subcutaneous treprostinil and 243 who received placebo at the time ADEs were ascertained...

BACKGROUND: Evaluating microcirculatory function in severely ill neonates is a relevant, unmet clinical need. Inappropriate peripheral microvascular vasodilatation is thought to contribute to cardiovascular alterations in preterm infants with acute respiratory distress syndrome (ARDS). We directly evaluated microcirculatory function in preterms with ARDS. METHODS: Peripheral microvascular function was assessed in 50 newborns, divided in three groups: preterms with ARDS; at-term newborns with mild-moderate congenital cardiac disease (Cardio group); healthy controls...
