LV Lead Positioning Guided by ICE With Vector Velocity Imaging. Introduction: Intraoperative modality for "real-time" left ventricular (LV) dyssynchrony quantification and optimal resynchronization is not established. This study determined the feasibility, safety, efficacy of intracardiac echocardiography (ICE), coupled with vector velocity imaging (VVI), to evaluate guide lead placement at time cardiac therapy (CRT) implant. Methods: One hundred four consecutive heart failure patients...
Leadless pacing systems are a viable alternative when extraction of an infected conventional system is required. pacemakers have also shown resistance to infection even inserted at the time or shortly after extraction.1,2 Our case documents rare occurrence Micra Transcatheter Pacemaker System (Medtronic, Minneapolis, MN) in patient with chronic recurrent transvenous device and successful retrieval this 4 months implantation.
The effectiveness and reliability of atrial leads has been questioned. We studied retrospectively, all implanted at our center (n = 494; 438 Medtronic Model 6957J, 56 4512) over a 5‐year period ending December 31, 1987, to determine the frequency lead failure (pacing, sensing, or both) median duration proper pacing sensing function for each model studied. Eighty‐eight percent polyurethane continued satisfactorily 5 years, results somewhat better than those reported heretofore in literature,...
When compared to patients with normal renal function, chronic kidney disease develop higher in-hospital complications post implantable cardioverter-defibrillator (ICD) therapy. However, real world data on ICD therapy in end stage (ESRD) is limited. In this study, we aim explore the procedure-related of ESRD.Using nationwide inpatient sample (NIS) database, conducted a retrospective analysis ESRD who underwent placement from 2010 2016. Using 1:2 propensity score matching, those function....
Key Teaching Points•Cardiac contractility modulation may be used as an adjunct for class III systolic heart failure, ejection fraction 25%–45%, not indicated biventricular pacing.•The giant myocardial protein titin plays a significant role in cardiac performance.•Cardiomyopathy accompanied by specific genetic mutation respond more favorably to therapy.IntroductionCardiac (CCM) the treatment of medically refractory chronic congestive failure (CHF) with (EF) 25%–45% pacing.1Borggrefe M.M.

Abstract Catheter ablation (CA) of the pulmonary veins for atrial fibrillation (AF) is growing exponentially and most commonly performed electrophysiologic procedure. Initial descriptions focused on CA paroxysmal AF, now more recently expanded in application to persistent AF those with comorbid heart failure. Efforts improve success have continue address issues such as vein “reconnection” following through different ablative energy modalities, use a “hybrid” surgical/endocardial combined...
Abstract Background Barriers to successful left ventricular lead placement within the coronary venous anatomy may include focal stenoses, thromboses, phrenic nerve stimulation, vessel tortuosity, small caliber, nonexcitable tissue, and valve presence. A large series describing utilization of angioplasty (CVAP) for relief these issues is absent in literature. Objective We report our experience on all patients treated with CVAP a single‐center 13‐year experience. Methods Forty‐seven (64% male,...

We report a 51‐year‐old man with severe ischemia cardiomyopathy and heart failure in whom incessant bigeminal ventricular ectopy failed to generate detectable arterial pressure. This created mechanical bradycardia despite an adequate electrical rate. Dual chamber pacing increased the effective rate allowed discontinuation of intraaortic balloon pump from which patient could not otherwise be weaned.
Methodology specific for moving superficial chronically implanted transvenous pacing leads to a subpectoral pocket is not described in the literature. Relocation of prepectoral and generator submuscular relief erosion pain with minimal pectoral trauma possible by applying variant previously submammary tunneling technique.All patients presenting device follow-up, elective battery replacement, or system upgrade over an 8-month period were considered relocation if experiencing significant...
There is no consensus regarding optimal methodology forblood pressure monitoring inpatients with a depressed ejection fraction undergoingcatheter ablationfor atrial fibrillation. Our goalswere to determine ifhemodynamicmanagementdifferences exist during radiofrequency ablation for fibrillation in patients and without an fraction< 50%, whether management was influenced by the utilization of invasive arterial blood monitoring. This single-center trial retrospectively compared catheterablation...
Questions remain as to how aggressively catheter ablation for atrial fibrillation may be applied patients with advanced systolic congestive heart failure, owing a historic under-representation in multicenter clinical trials. We sought describe the experience of persistent Class IV failure at our institution. All (left ventricular assist device excluded) between 2017 and 2020 referred radiofrequency were included. Out 10 patients, 7 agreed proceed, had restoration normal sinus rhythm upon...
