INTRODUCTION: The heart and the kidneys are tightly interlinked with each other. So, primary disorder of one of these organs often results in the secondary dysfunction of other. Such interactions play a vital role in the pathogenesis of a clinical entity called cardio-renal syndrome (CRS). CRS type 4 refers to the development of cardiac failure in the patients with CKD. OBJECTIVES: To study the prevalence of various cardiac diseases in the patients with CKD and risk factors for it...

Anxiety impairs both inhibition of distraction and attentional focus. It is unclear whether these impairments are reduced or exacerbated when loading working memory with non-affective information. Cardiac vagal control has been related to top-down regulation of anxiety; therefore, vagal control may reflect load-related inhibition of distraction under anxiety. The present study examined whether: (1) the enhancing and impairing effects of load on inhibition exist together in a non-linear function, (2) there is a similar association between inhibition and concurrent vagal control under anxiety...

Spinal cord injury (SCI) is a clinical syndrome encountered frequently in trauma centers and is accompanied by both acute and chronic heart rhythm abnormalities. The injury is characterized by sympathetic nervous system (SNS) impairment with preservation of parasympathetic output via the vagus nerve. Severe bradycardia in the form of life-threatening sinus arrest or complete heart block may be observed in the acute recovery phase. Therapy for arrhythmias in the acute phase includes atropine, intravenous chronotropes, methylxanthines for prevention of episodic bradycardia, and pacemaker implantation in severe cases...

A 61-year-old woman with symptomatic complete heart block was referred for permanent pacemaker. The presence of a left sided arteriovenous fistula and right sided mastectomy with lymph node dissection precluded the implantation of a trans-venous pacemaker and therefore, a leadless pacemaker was recommended. The patient also had an inferior vena cava (IVC) filter. The passage of a 27 French introducer sheath housing the leadless pacemaker through IVC filter was carefully visualized under fluoroscopy and advanced to the right ventricle without any compromise to the filter...

Neonatal Lupus Syndrome (NLS) is a distinct clinical entity caused by transplacental passage of maternal anti-SSA/Ro antibodies (Ab). Mothers may have systemic lupus erythematosus, Sjögren syndrome, or other connective tissue disease, or may be completely healthy at the time of giving birth. NLS includes several clinical manifestations: complete congenital heart block (CCHB) and cutaneous lupus are the most common, while hepatobiliary disease, hematological manifestations and central nervous system involvement may occur...

INTRODUCTION: For any surgery in the upper extremity that does not involve the shoulder, a supraclavicular block is preferred, as it is a safe procedure associated with rapid onset and reliable anaesthesia. Although ropivacaine has been extensively studied for epidural anaesthesia, very few reports exist on its use in supraclavicular brachial plexus block. AIM: This study was conducted to investigate and compare the effectiveness of supraclavicular brachial plexus anaesthesia with two different concentrations of ropivacaine (0...

Cardiac involvements are common in patients with Dermatomyositis, most of which are not severe enough to present definite or readily observable symptoms. However, Cardiovascular (CVS) manifestations constitute a major cause of death in these patients. The most frequently reported clinically evident of CVS manifestations in-patient of dermatomyositis are Congestive Heart Failure (CHF), conduction aberrations, that may predispose to complete heart block and coronary artery disease. The principal pathophysiological mechanisms that may produce these cardiac manifestations involve coronary artery disease as well as small vessels vasculitis of the myocardium...

The temporal resolution of the tomographic imaging method magnetic particle imaging (MPI) is remarkably high. The spatial resolution is degraded for measured voltage signal with low signal-to-noise ratio, because the regularization in the image reconstruction step needs to be increased for system-matrix approaches and for deconvolution steps in x-space approaches. To improve the signal-to-noise ratio, block-wise averaging of the signal over time can be advantageous. However, since block-wise averaging decreases the temporal resolution, it prevents resolving the motion...

W Randolph Chitwood
Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract. The Morrow operation has remained the gold standard for surgically treating this pathology...

BACKGROUND: Many epidemiological studies have established the relationship between hypertension and dyslipidemia. Calcium channel blockers (CCBs) are one of the first-line drugs for newly diagnosed patients with essential hypertension. Cilnidipine as a newer CCB acting by blocking both L- and N-type calcium channels possesses additional beneficial effects apart from lowering blood pressure (BP). The aim of this study was to evaluate the effectiveness of cilnidipine in patients with essential hypertension with borderline dyslipidemia and its effects on lipid profile...

BACKGROUND: Permanent pacemaker (PPM) implantation after cardiac surgery is required in 0.4-6% of patients depending on cardiac surgery type. PPM implantation in the early postoperative period may reduce morbidity and postoperative hospital stay. We performed a retrospective review of electronic medical records of adult patients with coronary artery bypass grafting (CABG), valve surgery, or both, over a 3-year period. Our aim was to identify predictors of PPM requirements and PPM dependency on follow-up in the current surgical era...

BACKGROUND: Complete atrioventricular block (CAVB) causes arrhythmogenic remodeling and increases the risk of Torsades de Pointes (TdP) arrhythmias. MicroRNAs (miRNAs) are key regulators of gene-expression that contribute to cardiac remodeling. OBJECTIVE: To assess miRNA changes after complete atrioventricular block (CAVB) and identify novel candidates potentially involved in arrhythmogenic cardiac remodeling. METHODS: CAVB was induced in mice via His bundle ablation...

Double right coronary artery (RCA) is an extremely rare coronary artery anomaly. We here report an atherosclerotic double RCA which appeared after primary percutaneous intervention performed to treat a 34-year-old male presenting with acute inferior myocardial infarction, cardiogenic shock and complete heart block. This is an unusual case as double RCA had been hidden by total atherosclerotic occlusion of the proximal part of the RCA and complete restoration of patency led complete heart block back to normal sinus rhythm...

OBJECTIVE: Mothers carrying anti-Ro antibodies are frequently referred for weekly echocardiograms to early detect and treat antibody-mediated fetal heart disease. We tested a surveillance strategy based on anti-Ro antibody titers. METHODS: From 2009-2014, 232 pregnancies were referred for maternal anti-Ro antibodies. At the baseline echocardiogram, anti-Ro titers were measured by ELISA and results categorized as negative (<8 U/ml; n = 43; excluded), low-moderate positive (8-49 U/ml; n = 62; group 1) or high positive (50- > 100 U/ml; n = 127; group 2)...

AIMS: Conventional aortic valve replacement (AVR), sutureless AVR (su-AVR) and transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) are associated with conduction abnormalities. The aim of the present study was to assess the incidence of left bundle branch block (LBBB) after su-AVR and TAVI, in comparison to conventional AVR. METHODS AND RESULTS: A total of 501 patients (mean age 74±8 years, 53% male) without preoperative cardiac conduction disturbances who underwent AVR or TAVI were included in the study...

Isolated left subclavian artery is one of the rarer aortic arch anomalies. It has been associated with other congenital heart diseases, typically tetralogy of Fallot, double-outlet right ventricle, and atrial and ventricular septal defects. Its significant clinical implications include a left-to-right shunt from the vertebrobasilar system, which causes pulmonary overcirculation and subclavian steal. We present an unusual case of a premature infant who was diagnosed prenatally with congenital complete atrioventricular block and tricuspid atresia and was found to have an isolated left subclavian artery postnatally...

Quadricuspid aortic valve is an extremely rare congenital heart anomaly that often causes valve incompetence, requiring surgical intervention. Care must be taken to avoid surgical complications in patients with quadricuspid aortic valve; thus, preoperative diagnosis is important. A 76-year-old man presented with exertional dyspnea due to aortic regurgitation. Transthoracic and transesophageal echocardiography revealed severe aortic regurgitation caused by quadricuspid aortic valve. To avoid interference with the cardiac conduction system, we performed aortic valve replacement using an ingenious technique, in which pledgeted sutures on the accessory leaflet were placed from outside the sinus of Valsalva to above the aortic annulus...

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...

BACKGROUND: The dural puncture epidural (DPE) technique is a modification of the combined spinal epidural (CSE) technique, where a dural perforation is created from a spinal needle but intrathecal medication administration is withheld. The DPE technique has been shown to improve caudal spread of analgesia compared with epidural (EPL) technique without the side effects observed with the CSE technique. We hypothesized that the onset of labor analgesia would follow this order: CSE > DPE > EPL techniques...
