BACKGROUND: Increased cardiac troponin I or T detected by high-sensitivity assays (hs-cTnI or hs-cTnT) confers an increased risk of adverse prognosis. We determined whether patients presenting with putatively normal, detectable cTn concentrations [> limit of detection and < upper reference limit (URL)] have increased risk of major adverse cardiovascular events (MACE) or all-cause mortality. METHODS: A prospective 5-year follow-up of patients recruited in the emergency department with possible acute coronary syndrome (ACS) and cTn concentrations measured with hs-cTnI (Abbott) and hs-cTnT (Roche) assays...

BACKGROUND: Copeptin levels in conjunction with cardiac troponin may be used to rule out early myocardial infarction in patients presenting with chest pain. Raised pre-operative copeptin has been shown to be associated with postoperative cardiac events. However, very little is known about the peri-operative time course of copeptin or the feasibility of very early postoperative copeptin measurement to diagnose or rule-out myocardial injury. OBJECTIVES: In this preparatory analysis for a larger trial, we sought to examine the time course of peri-operative copeptin and identify the time at which concentrations returned to pre-operative levels...

A subcutaneous implantable cardioverter-defibrillator (S-ICD) is an alternative device for prevention of sudden cardiac death, without any leads within the heart. Patients implanted with any type of ICD may need catheter ablation of ventricular tachycardia (VT) to reduce the overall arrhythmia burden (e.g., recurrent monomorphic VT) and lower the incidence of painful shocks induced by the device. Late gadolinium enhancement (LGE) MRI is a useful pre-test for guiding VT ablation, because it can be used to map myocardial scar and produce better outcomes...

AIM: Cardiopulmonary resuscitation guidelines suggest the lower sternal half be compressed. However, stroke volume has been assumed to be maximized by compressing the 'point' (P_max.LV) beneath which the left ventricle (LV) is at its maximum diameter. Identifying 'personalized' P_max.LV on computed tomography (CT), we derived and validated rules to estimate P_max.LV using posteroanterior chest radiography (chest_PA). METHODS: A retrospective, cross-sectional study was performed with non-cardiac arrest (CA) adults who underwent chest_PA and CT within 1h (derivation:validation = 3:2)...

INTRODUCTION: Adult-onset Still's Disease is a rare multisystemic inflammatory disease characterized by fever, maculo-papular erythematous rash and arthralgia. Adult-onset Still's disease is a diagnosis of exclusion. CASE REPORT: We report the case of a 33 years old man, hospitalized for fever, arthralgia and throat manifestations, leading to Adult-onset Stills's Disease diagnosis. Cardiac ultrasound revealed tricuspid vegetation. Once infectious causes were ruled out, the vegetation was related to Adult-onset Still's Disease according to Fautrel and Yamaguchi criteria...

About 60% of patients with paradoxical low-flow, low-gradient (PLF-LG) aortic stenosis (AS) have a severe disease that justifies aortic valve replacement (AVR). The first step in patients with symptomatic PLF AS should be to rule out measurement errors and treat hypertension. The second step is to distinguish pseudo-severe from true severe AS (TSAS). The third step is to select the optimal treatment modality at the right time. Regarding the second step, projected aortic valve area calculated using stress echocardiography is superior to traditional severity criteria (AVA < 1...

Pericardial effusion after midline cardiac surgery may be transudative or exudative. The exudative infective or haemorrhagic variety requires early surgical intervention. However there are rare cases of collections like chylomediastinum which should be ruled out. Their low incidence prompts to establish protocol for evaluating postoperative pericardial collections, which includes echocardiography and biochemical analysis of aspirate. The same is important from the perspective of management as chylopericardium may be successfully managed without surgical intervention by aspiration, pig tail insertion, dietary and medical management, which we demonstrate through our rare case which occurred after midline double valve replacement...

OBJECTIVE: Intraoperative cardiac arrest (CA) is usually attributable to pre-existing disease, or to intraoperative complications. In rare cases, intraoperative stress can demask certain genetic diseases, such as Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT). It is essential that neurosurgeons are aware of the etiologies, risk factors, and initial management of CA during surgery in the prone position. METHODS: We present a case of CA directly after spinal fusion for lumbar spondylolisthesis, and review the literature on cardiac arrests during spinal neurosurgery in the prone position...

BACKGROUND: There are four distinguishable types of THA devices in wide use, as defined by the femoral and acetabular bearing surfaces: metal-on-polyethylene (MoP), ceramic-on-polyethylene (CoP), metal-on-metal (MoM), and ceramic-on-ceramic (CoC). Metallic head THAs (MoP and MoM) can potentially induce cardiac toxicity because cobalt species, generated at the head-neck trunnion, and in the case of MoM devices, at the articular surface as well, can be absorbed systemically. However, studies have provided inconsistent results...

Background -Combining two signals of cardiomyocyte injury, cardiac troponin I (cTnI) and T (cTnT), might overcome some individual pathophysiological and analytical limitations and thereby increase diagnostic accuracy for acute myocardial infarction (AMI) with a single blood draw. We aimed to evaluate the diagnostic performance of combinations of high sensitivity (hs) cTnI and hs-cTnT for the early diagnosis of AMI. Methods -The diagnostic performance of combining hs-cTnI (Architect, Abbott) and hs-cTnT (Elecsys, Roche) concentrations (sum, product, ratio and a combination algorithm) obtained at the time of presentation was evaluated in a large multicenter diagnostic study of patients with suspected AMI...

Cutaneous neonatal lupus erythematosus (NLE) is a rare condition caused by the passive transfer of autoantibodies from mother to fetus. The disease most commonly presents itself with multiple erythematosus annular lesions or arcuate macules. In 10% of the cases, a cardiac anomaly can coexist. Appropriate diagnosis and laboratory and cardiac testing should be done to rule out any complications. Treatment usually includes topical steroids, following which the lesions will disappear after about eight weeks with no sequelae...

Yoshinori Kobayashi
In the clinical practice of cardiovascular critical care, we often observe a variety of arrhythmias in the patients either with (secondary) or without (idiopathic) underlying heart diseases. In this manuscript, the clinical background and management of various arrhythmias treated in the CCU/ICU will be reviewed. The mechanism and background of lethal ventricular tachyarrhythmias vary as time elapses after the onset of MI that should be carefully considered to select a most suitable therapy. In the category of non-ischemic cardiomyopathy, several diseases are known to be complicated by the various ventricular tachyarrhythmias with some specific mechanisms...

BACKGROUND: Atrial fibrillation (AF) is a growing financial burden on the healthcare system. Cardiac computed tomographic angiography (CCTA) is needed for pulmonary vein mapping before AF ablation (AFA). CCTA has shown to be an alternative to transesophageal echocardiogram (TEE) to rule-out left atrial appendage thrombus (LAAT) pre-AFA. We aim to examine the safety, cost-effectiveness, and time-efficiency of utilizing CCTA alone to rule out LAAT before AFA. METHODS: We prospectively screened patients with paroxysmal AF undergoing cryoablation...

Tricuspid regurgitation (TR) is a common valvular lesion which may affect morbidity and mortality. It can be related to an intrinsic abnormality of the tricuspid valve leaflets (organic) or secondary to annular dilatation (functional). Often organic and functional TR coexist in the same patient. A long standing TR is associated with ascites, congestive hepatopathy, peripheral edema, renal failure, and abdominal fullness which significantly affect the outcome. In particular, the perioperative course may be complicated due to both the presence of comorbidities and the development of a severe postoperative right ventricle (RV) dysfunction...
