Article Synopsis
- Atrial fibrillation (AF) is common among patients receiving cardiac resynchronization therapy (CRT) and affects the effectiveness of the treatment by reducing biventricular pacing (BiVp) beats.
- This study aimed to compare the effectiveness of rhythm control (using electrical cardioversion) versus rate control (using atrioventricular node ablation) strategies in CRT recipients suffering from persistent AF.
- Results showed that while both strategies improved BiVp percentage similarly, only patients who restored sinus rhythm experienced a significant increase in left ventricular ejection fraction (LVEF), indicating the importance of maintaining normal heart rhythm in these patients.
. The aim of the study was to assess the long-term influence of catheter ablation (CA) of different arrhythmias on cardiovascular implantable electronic devices (CIED) endocardial leads durability. .

Materials And Methods: The study included 223 patients with CRT (177 males), mean age 64.6±9.
Background: The influence of various factors on atrial fibrillation (AF) development in the population of tachycardia-bradycardia syndrome (TBS) patients remains unclear. There are no data on the impact of different right ventricular pacing percentage (RVp%) profiles.
Aim: The purpose of the study was to evaluate the relationship between the AF burden (AFB) and various clinical, echocardiographic, and pacing parameters in TBS patients.
Introduction: The prevalence of total coronary occlusion of an infarct‑related artery (IRA) and its impact on the outcome can differ between patients with non‑ST‑elevation myocardial infarction (NSTEMI) and those with ST‑segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI).
Objectives: We evaluated the impact of IRA occlusion on the outcome of myocardial infarction according to the presence or absence of ST‑segment elevation and the location of the culprit lesion.
Patients And Methods: We analyzed 4581 patients with STEMI and 2717 patients with NSTEMI who underwent PCI and were enrolled in the Polish Registry of Acute Coronary Syndromes.
Background: Some electrophysiological techniques, such as balloon cryoablation, involve the use of steerable sheaths of large diameter (outer diameter 15 Fr or more). Their introduction to the femoral vein may be difficult, especially in patients who have had numerous venipunctures in this area.
Aim: The authors describe a modification of typical venous access with the use of a "buddy wire" technique, facilitating the insertion of the cryoablation sheaths to the femoral vein.
Background: The only subgroups of patients with heart failure and atrial fibrillation in which the efficacy of cardiac resynchronization therapy has been scientifically proven are patients with indications for right ventricular pacing and patients after atrioventricular junction ablation. However it is unlikely that atrioventricular junction ablation would be a standard procedure in the majority of the heart failure patients with cardiac resynchronization therapy and concomitant atrial fibrillation due to the irreversible character of the procedure and a spontaneous sinus rhythm resumption that occurs in about 10% of these patients.
Methods/design: Pilot-CRAfT is the first randomized controlled trial evaluating the efficacy of a rhythm control strategy in atrial fibrillation patients with cardiac resynchronization therapy devices.
The authors present the case of a 62-year-old male patient with an implantable cardioverter-defibrillator and end-stage heart failure supported with an intra-aortic balloon pump. Implantation of a triple-site cardiac resynchronization system and complex heart failure treatment brought a significant improvement, return to home activity and 17-month survival. The patient died due to heart failure aggravation.

Aim: To identify additional CV risk factors and early signs of target organ damage in healthy individuals with HNBP.
Methods: Healthy volunteers (n = 74) with optimal blood pressure or HNBP were compared with respect to metabolic and haemodynamic parameters.
