Outcomes of Pediatric Patients Treated With Extracorporeal Membrane Oxygenation for Intractable Supraventricular Arrhythmias

Objectives: Extracorporeal membrane oxygenation is used to support refractory cardiorespiratory failure. Outcomes and complications when extracorporeal membrane oxygenation is used to support cardiorespiratory failure secondary to arrhythmia in pediatric patients remain poorly defined. Our purpose is to describe pediatric patients requiring extracorporeal membrane oxygenation support for supraventricular arrhythmias in the context of normal cardiac anatomy and congenital heart disease and identify patient/peri-extracorporeal membrane oxygenation variables associated with extracorporeal membrane oxygenation–related complications and survival. Design: Retrospective multicenter review from 1993 to 2016. Setting: Extracorporeal Life Support Organization registry. Subjects: Patients younger than 21 years old requiring extracorporeal membrane oxygenation support for supraventricular arrhythmias. Interventions: None. Measurements and Main Results: A total of 342 patients were identified (weight, 3.8 kg [3.2–7.5 kg]; age at extracorporeal membrane oxygenation initiation, 24 d [6–222]; 61% male). Sixty-five percentage survived to hospital discharge. Complications were frequent (85%) and most commonly cardiac related (31%). In multivariable modeling, mortality was associated with congenital heart disease, time from intubation to extracorporeal membrane oxygenation initiation, use of bicarbonate prior to extracorporeal membrane oxygenation, extracorpor...

Our study examined the association of plasma TMAO level with cardiovascular and all-cause mortality in hemodialysis (HD) patients. METHODS: Patients who were at least 18 years-old and received HD for at least 6 months were enrolled within 6 months. Patients with coronary heart disease, congestive heart failure, arrhythmia, or stroke within...

FromDr.Smith:A 40 something male complained of palpitations.  See the ECG below and how Ken Grauer dissects this grouped beating.===================================MY Comment by KEN GRAUER, MD (9/27/2020):===================================The 12-lead ECG and accompanying long lead II rhythm shown in Figure-1 was obtained from a 40-something year old man who was found to have a fairly slow and irregular heart rate. He was hemodynamically stable at the time this tracing was done. Imagine this is the only history available.What is the rhythm? Is this Wenckebach?Clinically  —...

AbstractPost-aortic left brachiocephalic vein (PALBV) is one of the rare congenital vessel abnormalities associated with congenital heart disease. As only a few reports of surgical treatment for thymic tumor in patients with PALBV are available, this study reports the case of a patient with PALBV who underwent surgical treatment for thymoma. In a 60-year old woman, a nodule in the anterior mediastinum was detected on chest computed tomography (CT) during examination for arrhythmia. Thymoma was suspected, and surgical resection was considered. PALBV was detected on a contrast CT scan before surgery. Video-assisted thoracosc...

AbstractAimsHypertension is a significant risk for the development of left ventricular hypertrophy, diastolic dysfunction, followed by heart failure and sudden cardiac death. While therapy with sacubitril/valsartan (SV) reduces the risk of sudden cardiac death in patients with heart failure and systolic dysfunction, the effect on those with diastolic dysfunction remains unclear. We hypothesized that, in the animal model of hypertensive heart disease, treatment with SV reduces the susceptibility to ventricular arrhythmia.Methods and resultsYoung adult female spontaneous hypertensive rats (SHRs) were randomly separated into ...

ConclusionsCryoablation of AVNRT with an 8-mm tip catheter in children appears to be safe, with an acceptable acute success rate and a low recurrence rate. A faster termination of AVNRT during the cryolesion, slowing down before ending with atrioventricular block, is a good indicator for acute success

General examination – eyes and facial dysmorphism Clinically examination is guided by the symptoms. Unless the history is not correlated with findings, important diagnostic possibilities may be missed. Clinical examination starts off with a focused general examination followed by a detailed examination of the cardiovascular system. Relevant points in other systems like basal crepitations, hepatosplenomegaly and neurological deficits should be looked for. Examination strategy should be fitting to the clinical situation. When a patient presents to the emergency room, it should be a short but focused examination to perm...

Atrial arrhythmias, i.e., intra-atrial reentrant tachycardia and atrial fibrillation, are a leading cause of morbidity and hospitalizations in adults with congenital heart disease (CHD). Little is known about their effect on quality of life and other patient-reported outcomes (PROs) in adults with CHD.

Adjuvant radiotherapy following breast-conserving surgery decreases local recurrences and improves survival outcomes in breast cancer [1,2]. However, radiotherapy is associated with an increased risk of cardiovascular complications as a result of cardiac irradiation, including ischemic heart disease [3-5], valvulopathy [3,6-9], congestive heart failure [3,5], myocarditis [9], arrhythmia [3] and myocardial infarction [5,10]. A case control study has demonstrated an increased risk of major coronary events by 7.4% for every Gy increase in mean dose to the heart [11].

(American Heart Association) Arrhythmias are irregular heartbeats and can be caused by a variety of factors, such as genetics, heart disease, high blood pressure or electrolyte imbalances.Many commonly used medications, including over-the-counter medicines, can cause or worsen arrhythmias.Health care professionals should consider that a patient's arrhythmia may be caused or worsened by a medication.

ConclusionsOsborn waves during TH had no significant effect on the survival and cerebral function of patients resuscitated SCA. However, appropriate ICD shocks due to the recurrence of VF were more frequent in patients with Osborn waves during long ‐term follow‐up.This article is protected by copyright. All rights reserved
