Management of Cardiac Implantable Electronic Devices in Patients With Severe Symptomatic Tricuspid Regurgitation—Proposed Algorithm and Selected Case Examples

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Severe tricuspid regurgitation (TR) is associated with significant morbidity and mortality. Management of severe TR includes treatment of the underlying cause(s), medical therapy and less commonly surgical tricuspid valve repair. Newer transcatheter tricuspid valve repair devices show promise for those patients who remain symptomatic with ...

Temporary epicardial left ventricular and biventricular pacing improves cardiac output after cardiopulmonary bypass

open access: yesJournal of Cardiothoracic Surgery, 2012
Background To evaluate, with different pacing modes, acute changes in left ventricular systolic function, obtained by continuous cardiac output thermodilution in various subsets of patients undergoing cardiopulmonary bypass surgery.

Right ventricular apex pacing: Is it obsolete?

open access: yesArchives of Cardiovascular Diseases, 2009
Clinical trials in patients with pacemakers for sinus node dysfunction or atrioventricular block have highlighted the fact that desynchronization of ventricular contraction induced by right ventricular apical pacing is associated with long-term morbidity and mortality.

Incidence and 1‐Year Prognostic of Unstable Angina After High‐Sensitivity Troponin Assessment

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Incidence and prognostic of unstable angina after high‐sensitivity troponin assesment is controversial. Aims This study evaluated prognostic of a contemporary population of patients with UA defined using high sensitive T troponin (T hs‐cTn) measurements and with significant coronary artery disease (CAD). Methods Consecutive patients

Transient 2:1 Atrioventricular Block with Peri-Conduction System Pacing After Leadless Pacemaker Implantation [PDF]

open access: yesTexas Heart Institute Journal
This report discusses a case of transient 2:1 atrioventricular block with conduction system pacing 4 hours after leadless right ventricular pacemaker implantation in a 19-year-old patient with a history of cardioinhibitory syncope and asystole cardiac ...

Comorbid CAD and Ventricular Hypertrophy Compromise The Perfusion of Myocardial Tissue at Subcritical Stenosis of Epicardial Coronaries [PDF]

open access: yes, 2018
BACKGROUND: Most studies of CAD revascularization have been based on and reported according to angiographic criteria which don't consider the relation between the resulting effective flow distal to the stenosis and the demand of a hypertrophied myocardial tissue.

Syncope with QT‐interval prolongation and T‐wave inversion in anterior and inferior leads: Foreboder of a life‐threatening condition?

open access: yesAnnals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
The patient’s ECG exhibited QT‐interval prolongation with T‐wave inversion in anterior and inferior leads that, together with CT‐pulmonary angiography findings, strongly suggested PE. This ECG pattern is crucial for diagnosing PE. Abstract Even though patients with pulmonary embolism usually present with respiratory distress and tachycardia, the ...

The incidence of in-hospital atrial fibrillation after coronary artery bypass grafting using ventricular and atrial pacing

open access: yesARYA Atherosclerosis, 2013
BACKGROUND: Atrial fibrillation (AF) after coronary artery bypass graft (CABG) surgery is a common problem. In this study, we sought to evaluate the safety and tolerance of continuous atrial pacing after CABG. We hypothesized that a strategy of temporary

Effects of right ventricular septum or His-bundle pacing versus right ventricular apical pacing on cardiac function: A systematic review and meta-analysis of randomized controlled trials

open access: yesJournal of International Medical Research, 2018
Objective Recent studies have demonstrated that right ventricular apical (RVA) pacing has a deleterious impact on left ventricular function, while right ventricular septum (RVS) or His-bundle pacing (HBP) contribute to improvements in cardiac function. A

Machine Learning‐Driven Discovery of Structurally Related Natural Products as Activators of the Cardiac Calcium Pump SERCA2a

open access: yesChemMedChem, EarlyView.
Heart failure involves reduced SERCA2a activity, crucial for calcium regulation in heart cells. This study reports machine learning screening of 57,423 natural products, identifying several structurally related SERCA2a activators. Three compounds enhance calcium transport in cardiac cells, despite off‐target effects, offering promising hits for ...
