OBJECTIVES: In recent years the impact of the left atrium (LA) has become more evident in different cardiovascular pathologies. We aim to provide LA parameters in healthy volunteers for cardiovascular magnetic resonance (CMR) using a fast approach. DESIGN: We analyzed 203 healthy volunteers (mean age 44.6 years (y), range 19y-76y) at 1.5 and 3.0 Tesla (T) using steady-state free precession (SSFP) cine in routine long axis view. Left atrial enddiastolic volume (LA-EDV), endsystolic volume (LA-ESV), stroke volume (LA-SV) and ejection fraction (LA-EF) were quantified and indexed to body-surface-area (BSA)...

OBJECTIVE: Changes in right ventricular (RV) structure and function following prolonged endurance training in athletes arise due to its unique anatomy and physiology. Arrhythmogenic cardiomyopathy (AC) should be differentiated from electrical, functional and structural adaptation of the heart in response to repetitive intense physical activity due to the negative contribution of exercise on AC progression and arrhythmic risk. DESIGN: For this review we performed a systematic search of the PubMed database up to October 2017 using terms and keywords pertaining to RV, athlete's heart (AH), AC, sudden cardiac death...

OBJECTIVES: Could a diastolic dysfunction and an increased LV-filling pressure according to ASE/EACVI guidelines be detected or ruled out by the E/a´ratio in patients with decreased ejection fraction. DESIGN: We retrospectively evaluated the diastolic function of 113 unselected in-hospital patients, aged 40-84 years, in sinus rhythm and with no or mild valve disease, having a decreased systolic function (EF ≤50%) using the new ASE/EACVI guidelines and compared these results with the E/a´ratio derived from the E wave in the mitral flow and the a´velocity in the tissue Doppler...

OBJECTIVES: Recurrent arrhythmia after pulmonary vein isolation (PVI) by radiofrequency (RF) ablation in patients with atrial fibrillation (AFIB) remains a significant challenge. Using contact force (CF) sensing ablation catheters, we aimed to identify procedure related parameters associated with recurrence after de-novo PVI in patients with AFIB. METHODS: Consecutive patients undergoing a de-novo PVI procedure (n = 120, 63% paroxysmal and 37% persistent AFIB) employing a force-sensing ablation catheter were included...

Venous return, the right heart function and the pulmonary circulation is an integrated functional unit. The right ventricle is particularly load sensitive, and will be influenced directly by the venous and pulmonary physiology. In this paper we present important physiological principles that govern the diagnosis and treatment of dysfunctions affecting the return of blood to the heart and the transfer of the cardiac output from the right to the left side. We do evaluate both basic science and the clinical literature pointing to practical aspects of physiological knowledge...

OBJECTIVES: Heart failure is a significant cause of mortality worldwide, and most current therapies treat only its symptoms. The results of cardiac stem cell research suggest a promising treatment option for heart failure, but there is currently an unmet demand for better research models. We have therefore, for the first time, isolated, expanded and differentiated progenitor cells obtained from juvenile pig hearts to use as a platform for cardiac stem cell research. DESIGN: Progenitor cells were isolated from the left ventricles of porcine hearts using collagenase enzymatic digestion and Percoll®-gradient centrifugation...

OBJECTIVES: Over recent decades implantable left ventricular assist devices (LVAD) have increased the possibility of improved survival in patients with advanced heart failure who also benefit from a better quality of life. The aim of this retrospective survey was to review the clinical results of LVAD implantation at a low-volume non-transplant centre (Linköping, Sweden) between 1993 and 2016. Our aim was also to assess the mortality and morbidity rates associated with implantation of three LVAD versions at our centre, and to compare our results with those from transplant centres...

OBJECTIVES: New onset postoperative atrial fibrillation (POAF) after cardiac surgery is associated with increased risk for thromboembolic complications. Compliance with anticoagulation treatment is prerequisite for successful outcome after POAF. We hypothesized that a disciplined anticoagulation protocol initiated instantly after POAF secures a long-term outcome. DESIGN: A total of 519 consecutive patients undergoing cardiac surgery were retrospectively analyzed...

OBJECTIVES: Comparisons between remote magnetic (RMN) and manual catheter navigation for atrial fibrillation (AF) ablation have earlier been reported with controversial results. However, these reports were based on earlier generations of the RMN system. DESIGN: To evaluate the outcomes of the most current RMN system for AF ablation in a larger patient population with longer follow-up time, 112 patients with AF (78 paroxysmal, 34 persistent) who underwent AF ablation utilizing RMN (RMN group) were compared to 102 AF ablation patients (72 paroxysmal, 30 persistent) utilizing manual technique (Manual group)...

OBJECTIVES: Pulmonary hypertension (PH) is a serious condition where diagnosis often is delayed due to unspecific symptoms. New methods to diagnose and differentiate PH earlier would therefore be of great value. The aim of this study was therefore to evaluate the relationship between circulating angiogenic and inflammatory biomarkers and various hemodynamic variables in relation to different causes of PH. DESIGN: Plasma samples from 63 patients at diagnosis were extracted from Lund Cardio Pulmonary Register, separated into pulmonary arterial hypertension (PAH, n = 22), chronic thromboembolic pulmonary hypertension (CTEPH, n = 15) and left heart disease (LHD) with (n = 21) and without (n = 5) PH...

Orthostatic intolerance is defined as the provocation of symptoms upon standing, commonly caused by neurogenic orthostatic hypotension (OH) and postural tachycardia syndrome (POTS), the etiology for which has not been fully uncovered yet. Many reports have described the occurrence of dysautonomia, orthostatic intolerance and POTS following febrile illness, presumably viral and post-vaccine. Furthermore, patients with dysautonomia have higher rates of autoimmune disorders such as Hashimoto thyroiditis and SLE...

OBJECTIVES: We explored the predictors and outcome of poor, versus good, initial TIMI flow in patients with acute coronary syndrome (ACS). DESIGN: We performed post-hoc analysis of a randomized trial of patients presenting with ACS who received 2 comparative stents. Poor initial TIMI flow was defined as baseline TIMI flow grade 0/1 at the initial coronary angiography. The primary endpoint was major adverse cardiac events (MACE): a composite of cardiac death, non-fatal myocardial infarction or ischemia-driven target lesion revascularization...
