Xiaoye Li, Ying Xue, Hongyi Wu
Purpose: To report a case of atrioventricular block (AVB) which might be associated with the right coronary artery lesion and the novel oral antithrombotic drug ticagrelor mediated by the increasing adenosine plasma concentration (APC). Case Report: A 65-year-old man was given loading dose of ticagrelor (180 mg) before coronary angiography with total thrombotic occlusion of right coronary artery and one stent was implanted. On second day after successful percutaneous coronary intervention, ECG monitoring showed second-degree (Mobitz type I) AVB with prolonged PR interval (299 ms)...

BACKGROUND: Atrioventricular (AV) block is usually due to infranodal disease and associated with a wide QRS complex; such patients often progress to complete AV block and pacemaker dependency. Uncommonly, infranodal AV block can occur within the His bundle with a narrow QRS complex. OBJECTIVES: The aims of this study were to define clinical/echocardiographic characteristics of patients with AV block within the His bundle and report progression to pacemaker dependency...

BACKGROUND: This study summarizes the clinical experience and 8-year follow-up results of the intraoperative device closure of ventricular septal defects (VSD). METHODS: From January 2009 to June 2017, 1,090 patients with isolated VSD were enrolled at our institute to participate in the study. The procedure involved a small lower sternal incision that was performed after full evaluation of VSD by transesophageal/transthoracic echocardiographic (TEE/TTE) guidance and the deployment of a domestically made occluder to close the VSD periventricularly and off cardiopulmonary bypass...

The authors report a case of a 68-year-old man who was diagnosed with an irreversible second-degree atrioventricular (AV) Mobitz II 2:1 block temporally associated with profound hyponatraemia. The cause of the hyponatraemia was beer potomania. The co-occurrence of reversible first, second and third-degree heart blocks and hyponatraemia has been described in a few published case reports. However, this case is noteworthy as the AV block persisted, despite correction of serum sodium concentration as opposed to other published cases, which meant that the patient required a permanent pacemaker...

For over 50 years, it has been known that the mitosis of eukaryotic cells is inhibited already at high hydrostatic pressure conditions of 30 MPa. This effect has been attributed to the disorganization of microtubules, the main component of the spindle apparatus. However, the structural details of the depolymerization and the origin of the pressure sensitivity have remained elusive. It has also been a puzzle how complex organisms could still successfully inhabit extreme high-pressure environments such as those encountered in the depth of oceans...

The Cardioband system is a transcatheter direct annuloplasty device that is implanted in patients with severe symptomatic functional mitral regurgitation (MR) due to annulus dilatation and high surgical risk. This device covers the posterior two-thirds of the annulus, from the anterolateral to the posteromedial commissure, implanted in close proximity of the left circumflex artery, atrioventricular (AV) conduction system, and coronary sinus. We present the case of an 80-year-old-gentleman with prohibitive surgical risk, treated with Cardioband implantation for functional MR with an evident P1-P2 cleft and P2-P3 indentation, a relative contraindication to MitraClip implantation...

New substances are constantly being added to the content of synthetic cannabinoids (SCs). SCs can affect the cardiovascular system and cause hypotension and bradycardia, myocardial infarction, atrial fibrillation, prolonged QTc, and Mobitz type II atrioventricular block. However, no cases associated with ventricular fibrillation (VF) have been reported to date. We report a case of a 26-year-old male patient admitted to the emergency department due to altered consciousness after SC use and requiring prolonged cardiopulmonary resuscitation due to resistant VF and cardiogenic shock...

Ras proteins are oncoproteins which play a pivotal role in cellular signaling pathways. All Ras proteins' signaling strongly depends on their correct localization in the cell membrane. Over 30% of cancers are driven by mutant Ras proteins, and KRas4B is the Ras isoform most frequently mutated. C6-ceramide has been shown to inhibit the growth activity of KRas4B mutated cells. However, the mechanism underlying this inhibition remains elusive. Here, we established a heterogeneous model biomembrane containing C6-ceramide...

Serotonin syndrome is a potentially fatal condition allied with increased serotonergic activity in the central nervous system. There are published data reporting serotonin syndrome induced by either tramadol or fentanyl in combination with selective serotonin reuptake inhibitors in adult patients; however, there are no reports of serotonin syndrome resulting from the combination of tramadol and fentanyl. We report a case of a 52-year-old woman who was admitted to cardiology service and who developed Mobitz Type II atrioventricular (AV) block after administration of oral tramadol and intravenous fentanyl...

We present a 21-year-old woman status post orthotopic heart transplantation initially presenting with a regular narrow complex tachycardia at 159beats/min. With intravenous diltiazem the rhythm transitioned to a regular tachycardia at 106beats/min, 2/3rd of the initial heart rate. We demonstrate this to be a novel description of 3:2second-degree Mobitz type I atrioventricular block (Wenckebach) with the absence of the hallmark regularly irregular (grouped beating) pattern.

Sarcoidosis is a systemic granulomatous disease of unknown aetiology, which is characterized by bilateral hilar lymphadenopathy and pulmonary disease. Clinically detected cardiac involvement occurs in 5% of sarcoid patients, although cardiac manifestations are discovered in 25% of the cases at autopsy. Sarcoid heart disease frequently causes atrioventricular block. The authors present the case of a 44-year-old man with bradycardia. On admission, second degree Mobitz II, then third degree atrioventricular block was diagnosed...

BACKGROUND: Type 1 myotonic dystrophy (DM1) patients' prognosis is very poor. Up until now, only a few prognostic factors for cardiovascular events have been identified, and they are predictive of end-stage disease. The aim was to assess the prognostic value of global longitudinal strain (GLS) for cardiovascular events in asymptomatic DM1 patients. METHODS: DM1 patients were included between 2011 and 2015 and followed up until January 2016. Patients underwent a transthoracic echocardiography at inclusion...

BACKGROUND: Epidemiological studies have linked exposures to ambient fine particulate matter (PM2.5 ) and traffic with autonomic nervous system imbalance (ANS) and cardiac pathophysiology, especially in individuals with preexisting disease. It is unclear whether metabolic syndrome (MetS) increases susceptibility to the effects of PM2.5 . We hypothesized that exposure to traffic-derived primary and secondary organic aerosols (P + SOA) at ambient levels would cause autonomic and cardiovascular dysfunction in rats exhibiting features of MetS...

There are many cases in the literature concerning the occurence of atrioventricular block in acute myocardial infarction. The prevelance and management of AV block in the setting of chronic myocardial ischemia remains unclear. Our case presented with stable angina pectoris. Treadmill test revealed Mobitz Type 2 AV block which disappeared with contrast injection and re-occured after injection during PCI.

A 26-year-old man presented to our syncope service with debilitating daily palpitations, shortness of breath, presyncope and syncope following a severe viral respiratory illness 4 years previously. Mobitz type II block had previously been identified, leading to a permanent pacemaker and no further episodes of frank syncope. Transthoracic echocardiography, electophysiological study and repeated urine metanepherines were normal. His palpitations and presyncope were reproducible on deep inspiration, coughing, isometric hand exercise and passive leg raises...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of liver disease in developed countries. The association of NAFLD with conduction defects is unknown. The aim of our study was to find whether an association exists between conduction defects and NAFLD. METHODS: This is a case-control retrospective study of 700 patients admitted to Orange Park Medical Center, Orange Park, Florida from 2009 to 2015. Patients with a history of alcohol use, congenital heart disease, infiltrative malignancy, and myocarditis were excluded from the study...

We have studied the formation and functional properties of polyelectrolyte multilayers where calmodulin (CaM) is used as a polyanion. CaM is known to populate distinct conformational states upon binding Ca(2+) and small ligand molecules. Therefore, we have also probed the effects of Ca(2+) ions and trifluoperazine (TFP) as ligand molecule on the interfacial structures. Multilayers with the maximum sequence PEI-(PSS-PAH)x-CaM-PAH-CaM-PAH have been deposited on silicon wafers and characterized by X-ray and neutron reflectometry...

A Mobitz type I block (Wenckebach phenomenon) with narrow QRS complex is almost always due to a lesion in the AV node. In a type I block with wide QRS complex (>0.12sec), the block can be in the His-Purkinje system in 60-70% of the cases. Even though the progressive PR prolongation with every conducted beat suggests Wenckebach phenomenon, one needs to pay attention to the accompanying QRS complex. In the setting of persistent right bundle branch block, axis change of subsequent conducted beat before an unconducted p suggests alternating fascicular block, giving clue to unreliable infra-Hisian conduction; and in the setting of symptoms, a pacemaker should be implanted...
