OBJECTIVE: To investigate the effect of the operator knowing the real-time contact force (CF) on the efficacy of pulmonary vein antrum isolation (PVAI). METHODS: Fifty patients with paroxysmal atrial fibrillation (AF) or short lasting persistent AF were randomized to CF guided PVAI (n = 25) or conventional PVAI (n = 25). In the CF guided group, CF between 10 and 40 grams (g) was aimed at. Efficacy of PVAI was measured as reduction in AF burden (AFB) and time to AF recurrence detected by implantable cardiac monitor (ICM), inserted 3 months before PVAI...

OBJECTIVE: Epidemiological studies suggest that women with loss of ovarian function at early ages may be especially burdened by cardiovascular disease (CVD). In this study, we aimed to evaluate pulse wave velocity and myocardial performance index in patients with premature ovarian insufficiency (POI). DESIGN: We enrolled 51 female patients (mean age 38.9 ± 6.7 years) with POI and 49 healthy subjects (mean age 36.8 ± 5.2 years). All participants underwent a detailed echocardiographic examination and pulse wave velocity (PWV) measurement which is basically the velocity of pulse wave travelling from carotid to femoral artery...

OBJECTIVES: Implantable cardioverter defibrillator (ICD) treatment is effective among long QT syndrome (LQTS) patients at a high risk of sudden cardiac death. Previous studies show that the international guidelines are not always followed, and that risk stratification may be based on genotype rather than individual risk profile. We analysed data from the Swedish ICD & Pacemaker Registry and medical records to examine how international guidelines were followed with regards to phenotype and genotype...

OBJECTIVES: We explored the educational gradient in mortality in atrial fibrillation (AF) patients. DESIGN: We prospectively followed patients hospitalized with AF as primary discharge diagnosis in the Cardiovascular Disease in Norway 2008-2012 project. The average length of follow-up was 2.4 years. Mortality by educational level was assessed by Cox proportional hazard models. Population attributable fractions (PAF) were calculated. Analyses stratified by age (≤75 and >75 years of age), and adjusted for age, gender, medical intervention, and Charlson Comorbidity Index...

Right ventricular (RV) failure after cardiac surgery is associated with an ominous prognosis. The etiology of RV failure is multifaceted and the ability to recognize RV failure early is paramount in order to initiate timely treatment. The present review focuses on different diagnostic modalities for RV function and discusses the normal versus abnormal findings in RV monitoring after cardiac surgery and the limitations of the applicable diagnostic modalities. There are specific challenges in RV assessment after cardiac surgery due to a loss of longitudinal contraction and a concomitant gain of transverse contraction...

OBJECTIVES: The effect of long-term adaptive servo-ventilation (ASV) on cardiovascular mortality and admission rates in patients with chronic heart failure (CHF) and Cheyne-Stokes respiration (CSR) has not been much studied. The aim of this study was primarily to investigate whether ASV therapy significantly reduced these parameters. DESIGN: We included 75 CHF patients on optimal medication and CSR ≥25% of sleeping time, in New York Heart Association (NYHA) classes II-IV and left ventricular ejection fraction (LVEF) ≤ 45%...

PURPOSE: Coronary angiography provides no details on underlying pathology in acute coronary syndromes (ACS). Optical coherence tomography (OCT) can visualize coronary atherosclerosis, thrombus formation, and plaque rupture in patients with myocardial infarction (MI) where coronary angiography is unclear. MATERIALS AND METHODS: We present a case series containing six young patients with ACS, four of them due to non-obstructive thrombus, in whom the operators refrained from stent implantation despite an identifiable culprit lesion with OCT-validated thrombus formation...

OBJECTIVES: Up to 50% of patients qualified for cardiac resynchronization therapy (CRT) have documented atrial fibrillation (AF) prior to CRT-implantation. This finding is associated with worse prognosis but few studies have evaluated the importance of post-implant device-detected AF. This study aimed to assess the prognostic impact of device-detected atrial high-rate episodes (AHRE), as a surrogate for AF. DESIGN: Data were retrospectively obtained from consecutive patients receiving CRT...

OBJECTIVES: Transcatheter aortic valve implantation (TAVI) is an established treatment for high-grade aortic valve stenosis in patients found unfit for open heart surgery. The method may cause cardiac conduction disorders requiring permanent pacemaker (PPM) implantation, and the long-term effect of PPM implantation remains ambiguous. Design One hundred sixty-eight patients who underwent TAVI from 2008 to 2012 were included. Patient characteristics, ECGs and PPM data were collected through medical records...

OBJECTIVES: To study pre- and postoperative atrial fibrillation and its long-term effects in a cohort of aortocoronary bypass surgery patients. DESIGN: Altogether 615 patients undergoing aortocoronary bypass graft surgery in 1999-2000 were studied. Forty-four (7%) had preoperative atrial fibrillation. Postoperative atrial fibrillation occurred in 165/615 patients (27%) while 406/615 patients (66%) had no atrial fibrillation. After a median follow-up of 15 years, symptoms and medication in survivors were recorded, and cause of death in the deceased was obtained...

OBJECTIVES: The mechanisms of the location and extension of acute aortic dissection (AD) are only poorly understood. The aim of this study was to compare the cohesion of the non-coronary aortic sinus (NAS) and the ascending aortic wall (AA) using the Dissectometer - a new device for analyses of the mechanical properties of the aorta. DESIGN: The properties of the aortic wall were analyzed with the "Dissectometer" (parameters P7, P8 and P9) in adult patients undergoing aortic root (AR) replacement in two different segments: NAS and AA...

OBJECTIVES: To test if cardiac computed tomography angiography (CCTA) can be used in the triage of patients at high risk of coronary artery disease. DESIGN: The diagnostic value of 64-detector CCTA was evaluated in 400 patients presenting with non-ST segment elevation myocardial infarction using invasive coronary angiography (ICA) as the reference method. The relation between the severity of disease by CCTA and a combined endpoint of death, re-hospitalization due to new myocardial infarction, or symptom-driven coronary revascularization was assessed...

OBJECTIVES: Acute STEMI is routinely treated by acute PCI. This treatment may itself damage the tissue (reperfusion injury). Conditioning with GLP-1 analogs has been shown to reduce reperfusion injury. Likewise, ischemic postconditioning provides cardioprotection following STEMI. We tested if combined conditioning with the GLP-1 analog liraglutide and ischemic postconditioning offered additive cardioprotective effect after reperfusion of 45 min coronary occlusion of left anterior descending artery (LAD)...

OBJECTIVES: Longer-term electrocardiographic effects of multiple inappropriate ICD shocks were investigated to study their hypothesized pro-arrhythmic potential. DESIGN: Thirteen male patients with ischemic cardiomyopathy who received ≥2 inappropriate shocks within 24 h and for whom 12-lead ECGs were available both before and within 72h after the inappropriate shocks were analyzed. Exclusion criteria included continuous ventricular pacing, underlying AF, events within 6 weeks after lead implantation and concomitant acute medical problems...

OBJECTIVE: The indications for and the risk and benefit of concomitant surgical ablation for atrial fibrillation (AF) have not been fully delineated. Our aim was to survey whether the Cox-maze IV procedure is associated with postoperative heart failure (PHF) or other adverse short-term outcomes after mitral valve surgery (MVS). DESIGN: Consecutive patients with AF undergoing MVS with (n = 50) or without (n = 66) concomitant Cox-maze IV cryoablation were analysed regarding perioperative data and one-year mortality...

OBJECTIVES: Growing number of patients with terminal heart failure and a shortage of heart donors have increased use of short- and long-term mechanical circulatory support (MCS). Few studies have analyzed survival rates and healthcare costs for heart transplantation (HTx), with or without extracorporeal membrane oxygenation (ECMO) and left ventricular assist device (LVAD). DESIGN: In a retrospective, single-center study, data were analyzed from patients listed for HTx who died on the waiting list (DWL, n = 12), underwent HTx (n = 206), had ECMO as bridge to HTx (ECHTx, n = 15), or received LVAD treatment, either isolated (LVAD, n = 19) or bridging to HTx (LVADHTx, n = 26) during 2005-2012...

OBJECTIVES: Cryoablation (CRYO) is an alternative to radiofrequency (RF) for catheter ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL). We aimed to study whether different CTI morphologies had different impacts on procedural success for CRYO and RF. DESIGN: This study randomized 153 patients with CTI-dependent AFL (median age 65 years; range 34-82) to RF or CRYO (78 CRYO; 75 RF). Biplane angiography (RAO 30° and LAO 60°) was done before the ablation procedure and isthmuses were classified as straight (n = 81), concave (n = 43) or pouch-like (n = 29)...

OBJECTIVES: Surgically treated type-A aortic dissection patients are often restricted from physical exercise due to a lack of knowledge about the blood pressure increase. Our aims were to evaluate the hemodynamic responses during exercise, and to assess changes in peak oxygen uptake, maximal workload, and quality-of-life after completion of an exercise-based cardiac rehabilitation program. DESIGN: Three subgroups were retrospectively identified based on their different eligibility criteria...
