Remote Magnetic Navigation for VT Ablation. Background: This study aimed to compare acute and late outcomes of ablation using the magnetic navigation system (MNS) manual techniques (MAN) in patients with (SHD) without (NSHD) structural heart disease. Methods: Ablation data 113 consecutive (43 SHD, 70 NSHD) ventricular tachycardia treated catheter at our center were analyzed. Success rate, complications, procedure, fluoroscopy, times, recurrence rates systematically recorded all patients....
Contact Force in Ventricular Tachycardia Ablation Background Poor catheter‐to‐myocardial contact can lead to ineffective ablation lesions and suboptimal outcome. force (CF) sensing catheters ventricular tachyarrhythmia (VT) ablations have not been studied for their long‐term efficacy. Purpose The aim of this study was compare CF manual (MAN) remote magnetic navigation (RMN) safety efficacy acute Methods A total 239 consecutive patients who underwent VT with the use MAN, CF, or RMN were...
Early Repolarization in Noncompaction Cardiomyopathy. Background: repolarization (ER) is associated with malignant ventricular arrhythmias, including fibrillation (VF) and sudden cardiac death (SCD). One possible mechanism increased trabeculation deep intramyocardial invagination, carrying the Purkinje system deeper into myocardium resulting delayed depolarization inhomogenous repolarization. cardiomyopathy (NCCM) a recently classified, primary excessive trabeculations. In these patients...
The very long-term mortality of off-pump and on-pump coronary artery bypass grafting (CABG) versus percutaneous intervention (PCI) in a randomized complex disease population is unknown. This study aims to investigate the impact CABG PCI on 10-year all-cause mortality.The SYNTAX trial 1800 patients with three-vessel and/or left main or assessed their survival at 10 years. In this sub-study, hazard over years was compared according technique revascularization: (n = 725), 128) 903).There...
AimsAfter initial catheter ablation, repeat procedures could be necessary. This study evaluates the efficacy of magnetic navigation system (MNS) in ablation as compared with manual conventional techniques (MANs).
Harvest of the left internal mammary artery (LIMA) is a technically demanding element minimally invasive coronary surgery. We aimed to evaluate learning curve thoracoscopic, nonrobotic LIMA harvest during endoscopic bypass (Endo-CAB) surgery.Eighty patients undergoing Endo-CAB surgery were included. was performed using commonly available video-assisted thoracoscopic instruments. Time from incision until heparin administration defined as total time (this includes opening pericardium and...
Sutureless and rapid-deployment aortic valve prostheses are frequently used for the treatment of stenosis. However, postoperative left bundle branch block (LBBB) permanent pacemaker (PPM) implantation have emerged as frequent complications. The aim this study was to compare incidence new-onset LBBB PPM after sutureless replacement (sAVR) with stented bioprostheses, impact on survival.Patients undergoing isolated surgical (AVR) or concomitant AVR coronary artery bypass surgery between January...
Atrial tachycardias (ATs) frequently develop in patients with congenital heart defects (CHDs). This study aimed to evaluate the effects of extensive atrial scar formation on total activation time (TAAT) and its relation tachycardia cycle length (CL) classify AT. Seventy-one were included divided into two groups: without CHD (Group I, 35 patients) II, 36 patients). All underwent CARTO electroanatomical mapping. Two subgroups created: centrifugal (CAT) or macroreentrant AT (MRAT). Total time,...
Remote magnetic navigation (RMN) is an alternative to manual catheter control (MCC) radiofrequency ablation of right ventricular outflow tract (RVOT) arrhythmias. The data support RMN approach limited. We aimed investigate the clinical and procedural outcomes in a cohort patients undergoing RVOT premature complex/ventricular tachycardia (PVCs/VT) procedures using vs. MCC. Data was collected from two centres. Eighty-nine consecutive PVCs/VT were performed 75 patients; RMN: 42 MCC: 47...
The need for permanent pacemakers (PMs) after heart transplantation (HT) is increasing. aim was to determine the influence of cardiac allograft vasculopathy (CAV), donor age, and other risk factors on PM implantations early late HT its effect survival.A retrospective, single-centre study performed including HTs from 1984 July 2018. Early defined as implantation ≤90 days > 90 days. Risk survival were determined with (time-dependent) multivariable Cox regression. Out 720 performed, 62 excluded...
Aortic valve replacement in a patient with an aortic homograft can be very challenging, especially when concomitant mitral surgery needs to performed. We report case of implantation sutureless bioprosthesis combined severely calcified where conventional was technically unfeasible. believe that AVR is viable option for young patients high surgical risk cannot achieved.
Transfusion of blood products after coronary artery bypass grafting (CABG) is associated with increased morbidity and mortality. We evaluated the perioperative use in patients undergoing CABG our institution over past two decades.The study included 18 992 who underwent isolated at hospital between 1998 2017. Baseline characteristics number transfusions during their stay (including red cells [RBCs], platelets, fresh frozen plasma [FFP]) were assessed. Logistic regression models used to...
Objective Ablation of atrioventricular nodal re-entrant tachycardia (AVNRT) is a highly eff ective procedure both with radiofrequency (RF) and cryoenergy (CE). Conventionally, it requires several diagnostic catheters hospital admission. This study assessed the safety effi cacy simplified approach using magnetic navigation system (MNS) compared to CE manual RF ablation (MAN).Methods results In MNS group single magnetic-guided quadripolar catheter was inserted through internal jugular vein...
Background After catheter ablation there is often a discrepancy between acute and chronic success rates. We aimed to evaluate major determinants for lesion quality understand different manifestations of structures. Methods In canine thigh muscle model radiofrequency (RF) current was delivered 60 seconds at 30 W (n = 39) or 50 18) with 15‐g contact force. A second‐generation 12‐hole gold open irrigation (SGIT) first‐generation six‐hole platinum‐iridium (FGIT; Biotronik, Berlin, Germany) were...
Background: Noncompaction cardiomyopathy (NCCM) is considered to be the result of an arrest in normal myocardial embryogenesis.The histological, developmental, and electrophysiological explanation ventricular arrhythmias NCCM still unknown.The aim this study was determine origin premature contractions (PVCs) identify any predominant arrhythmic foci. Methods: Retrospective data from our registry including 101 patients were analyzed.A total number 2069 electrocardiograms (ECGs) studied...
