Effectiveness of a percutaneous left ventricular assist device in preventing acute hemodynamic decompensation during catheter ablation of ventricular tachycardia in advanced heart failure patients: a retrospective single ‐center analysis

AbstractIntroductionAcute hemodynamic decompensation during catheter ablation of ventricular tachycardia is associated with increased mortality. We assessed the effectiveness of mechanical circulatory support using a micro ‐axial percutaneous assist device in preventing acute hemodynamic decompensation.Methods and resultsTwenty ‐six consecutive patients with structural heart disease undergoing 28 ventricular tachycardia ablations between May 2013 and October 2017 were included. All patients presenting with left ventricular ejection fraction

We describe a family ascertained through 3 newborn screening (NBS) positive infants found to be unaffected themselves but in whom the mothers (sisters) were affected. There were also two affected children born to an affected male and his heterozygous wife who were false negatives on NBS but had increased fractional excretion of free carnitine in the urine. Analysis on a Next Generation Sequencing panel specifically designed to fully cover newborn screening disease targets showed a homozygous change in the five probands (SLC22A5; NM_003060:c.-149G > A; p.?). The mutation segregates with the CUD within the family. It ...

CONCLUSIONS: Abnormally high ABI appears to be associated with an increased risk of a composite of CVD/all-cause mortality in suspected or established CVD patients but not in the general population. However, additional well-designed studies are required to support the current findings. PMID: 31814377 [PubMed - as supplied by publisher]

ConclusionPatients who are at risk for SCA are patients who have had a cardiac arrest due to ventricular fibrillation (VF) or sustained ventricular tachycardia (SVT), those with familial or inherited condition with sudden cardiac arrest risk, myocardial infarction with an ejection fraction (EF) of less than or equal to 35%, dilated cardiomyopathy (including NICM), with an EF of less than or equal to 35%, ICD explanations, and other conditions with high risk of ventricular tachycardia (VT) or VF are candidates for the WCD.The sample of data was from 186 patients. However, more patients were likely candidates but may not hav...

Written by Pendell Meyers, reviewed by Steve Smith and Scott Weingart“Idiopathic ventricular tachycardias” refer to a group of tachydysrhythmias originating below the AV node and bundle of His but differing in etiology, prognosis, and treatment compared to classic ventricular tachycardia (VT). The name “idiopathic” is becoming more and more inappropriate, as various specific subgroups and specific etiologies are being discovered, including right ventricular outflow tract VT, fascicular VT, and bundle branch reentrant VT. To understand these entities one must first understand the differences between ...

Written by Pendell Meyers, with edits by Steve SmithA male in his 60s with history of HTN and previous complaint of palpitations but with a negative holter monitor workup, presented to our ED with palpitations for the past hour, associated with lightheadedness and presyncope.He was hemodynamically stable and well appearing, but was symptomatic with palpitations and lightheadedness.Here is his 12-lead on arrival:What do you think?There is a regular, seemingly wide complex tachycardia at 224 beats per minute. The computer QRS duration is calculated at 178ms, but I believe the true QRS duration is much shorter, and in most le...

Conclusions: In HCM, unlike ischemic heart disease, prevention of sudden death with ICD therapy is unassociated with significant increase in cardiovascular morbidity or mortality, or transformation to heart failure deterioration. ICD therapy does not substantially impair overall psychological and physical well-being.

AbstractPurpose of ReviewVentricular arrhythmias (VAs) are a significant cause of morbidity and mortality in patients with cardiomyopathy (CM). This review focuses on ventricular tachycardia (VT) management in uncommon causes of heart disease, such as inflammatory and infiltrative CMs.Recent FindingsIntegration of advanced cardiac imaging modalities, such as cardiac magnetic resonance imaging (MRI) and positron emission tomography (PET), into diagnostic evaluation of patients with CM may unmask abnormal myocardial substrate in almost half of patients presenting with VAs. Stepwise approach to management of VAs in cardiac sa...
