BACKGROUND: Sarcoidosis is a systemic disease of unknown etiology, in which granulomas develop in various organs, including the skin, lungs, eyes, or heart. It has been reported that patients with sarcoidosis are more likely to develop panic disorder than members of the general population. However, there are many unknown factors concerning the causal relationship between these conditions. CASE PRESENTATION: We present the case of a 57-year-old woman who appeared to have panic disorder, as she experienced repeated panic attacks induced by transient complete atrioventricular block, associated with cardiac sarcoidosis...

INTRODUCTION: Atrioventricular node (AVN) contusion usually results in cardiogenic shock and arrhythmia and is a rare but fatal condition. The condition is difficult to diagnose and easily overlooked because it develops rapidly and is asymptomatic. We here report 3 cases that demonstrate blunt chest impact and hemorrhages of the posterior atrioventricular junction, eventually result in death. CLINICAL FINDINGS: Autopsy and histological examination were performed on all cases...

This study sought to clarify the effects of reduced feeding on physiological parameters in dogs to enable appropriate evaluations of the safety and toxicity of test compounds. We measured alkaline phosphatase isozymes and the circulating blood volume, as well as clinical signs, body weight, hematology, blood chemistry, electrocardiography, organ weight, and histopathology, in male beagle dogs fed a diet consisting of 300 g/day or 150 g/day for 4 weeks. There were no abnormal clinical signs in any of the dogs...

The recent technical advances allow the use in practice of three-dimensional echocardiography in children especially through the new high frequency matrix probe. It is difficult or even impossible to hold breathing during children' acquisition so to avoid motion full volume artifact, one beat and live 3D modes are suitable. 3D echocardiography is more accurate than 2D to assess the size, location, and relationship with surrounding structures of atrial and ventricular septal defects and thus helps in the therapeutic decision...

We recently reported the feasibility of a handmade left atrioventricular valve using decellularized extracellular matrix for 3 months in a failed repair of AV canal defect. We present the use of an extracellular matrix mitral valve for 9 months in an infant with an un-repairable congenitally malformed valve. The valve functioned perfectly without anticoagulation until the patient expired from non-cardiac complications of their fibrillin gene defect. This report adds further experience using valves made from extracellular matrix in the systemic ventricle both in terms of application and in terms of short-term durability of the construct...

The 24-hr electrocardiogram (ECG) interpretation in patients with double-chamber pacemakers may be challenging. The difficulty increases if not well-known pacemaker algorithm and device malfunction coexist. We show atrial synchronization pace (ASP) in a patient with ventricular lead damage. We provide detailed description of electrocardiogram and intracardiac electrogram. ASP may confuse 24-hr ECG monitoring interpretation, especially in patients with ventricular lead dysfunction.

INTRODUCTION AND OBJECTIVES: The association of univentricular heart with double inlet and Ebstein's "like" anomaly of the common atrioventricular valve is extremely rare. METHODS: Two hearts with this association are described with the segmental sequential system which determine the atrial situs, the types of atrioventricular and ventriculoarterial connections and associated anomalies. RESULTS: Both hearts had atrial situs solitus, and a univentricular heart with common atrioventricular valve, a foramen primum and double outlet ventricle with normal crossed great arteries...

INTRODUCTION AND OBJECTIVES: Currently, studies on the leadless pacemaker (Micra) have mostly been limited to clinical trials with less than 6 months' follow-up and they often fail to reflect real population outcomes. We sought to evaluate electrical parameters at implantation and chronologically during follow-up, as well as the safety of this new technique. METHODS: This prospective, observational study included 30 consecutive patients, all ≥ 65 years, with an indication for single-chamber pacemaker implantation...

BACKGROUND: Single-ventricle palliation (SVP) for children with unbalanced atrioventricular septal defect (uAVSD) is thought to carry a poor prognosis, but limited data have been reported. METHODS: We performed a retrospective review of children with uAVSD who underwent SVP at a single institution. Data were obtained from medical records and correspondence with general practitioners and cardiologists. RESULTS: Between 1976 and 2016, a total of 139 patients underwent SVP for uAVSD...

BACKGROUND: Swine are a well-recognized animal model for human cardiovascular diseases. Despite the widespread use of porcine model in experimental electrophysiology, still no reference values for intracardiac electrical activity and conduction parameters determined during an invasive electrophysiology study (EPS) have been developed in this species thus far. OBJECTIVES: The aim of the study was to develop a set of normal values for intracardiac electrical activity and conduction parameters determined during an invasive EPS of swine...

Background. Congenital heart block is characterized by blockage of electrical impulses from the atrioventricular node (AV node) to the ventricles. This blockage can be caused by ion channel impairment that is the result of genetic variation. This study aimed to investigate the possible causative variants in a Thai family with complete heart block by using whole exome sequencing. Methods. Genomic DNA was collected from a family consisting of five family members in three generations in which one of three children in generation III had complete heart block...

Plasma 5-hydroxytryptamine (5-HT; serotonin), released from blood platelets, plays a major role in the human cardiovascular system. Besides the effect of endogenous serotonin, many drugs targeting serotonergic receptors are widely used in the general population (antiobesity agents, antidepressants, antipsychotics, antimigraine agents), and may enhance the cardiovascular risk. Depending on the type of serotonin receptor activated and its location, the use of these compounds triggers acute and chronic effects...

OBJECTIVES: Prosthetic valve dehiscence after aortic valve surgery in Behçet's disease patients is common. We aimed to validate the usefulness of our new technique 'subannular endomyocardial implantation of valve prosthesis' designed to prevent prosthetic valve dehiscence. METHODS: Subannular endomyocardial implantation of valve prosthesis involves suturing the sewing cuff of the valve prosthesis in the endomyocardium below the aortic annulus, which is based on the idea that annular tissue should be excluded from the suture line in Behçet's disease patients...

BACKGROUND: A major drawback of the transcatheter aortic valve replacement (TAVR) procedure using the self-expandable Medtronic CoreValve (MCV) prosthesis is the high incidence of conduction disturbances and the need for postprocedural permanent pacemaker (PPM) implantation. The depth of prosthesis implantation may be an important contributing factor. The study aim was to determine the relationship between angiographic measurements of the MCV prosthesis depth and the occurrence of new conduction disturbances and need for PPM after TAVR...

Regular narrow QRS tachycardia, particularly if well-tolerated, is usually considered a "benign" arrhythmia of a supraventricular origin. This case concerns an 82-year-old male with ischemic heart disease who presented with recurrent episodes of a narrow QRS tachycardia that was initially diagnosed and treated as atrial tachyarrhythmia. However, careful physical examination and ECG analysis established the correct diagnosis, and the patient was managed appropriately. Remarkably, the observation of irregular cannon A waves, and Lewis lead recording, confirmed atrioventricular dissociation during tachycardia and indicated its underlying mechanism...

We report the case of a pulsatile mass found in a patient who presented for a routine echocardiogram. The mass turned out to be an exceedingly rare mitral-subannular pseudoaneurysm involving the membranous atrioventricular septum with systolic expansion protruding into right atrium, discovered late after repeated multiple valve replacement surgery. Although these pseudoaneurysms may present asymptomatically, surgical intervention might be indicated because of the risk of rupture. This report describes this rare finding, discusses possible pathophysiological mechanisms, and underscores the importance of multimodality imaging to achieve correct identification and delimitation to guide surgical intervention in such cases...
