View article: Comparable Benefits in Heart Failure Hospitalization and Survival with Sacubitril/Valsartan Therapy in CRT Nonresponders and HFrEF Patients Without CRT Indication
Comparable Benefits in Heart Failure Hospitalization and Survival with Sacubitril/Valsartan Therapy in CRT Nonresponders and HFrEF Patients Without CRT Indication Open
Background: Sacubitril/valsartan (S/V) improves left ventricular (LV) function and clinical outcome in heart failure (HF) with reduced ejection fraction (HFrEF). Data on its clinical value in the specific cohort of HFrEF patients demonstra…

Pacemakerkezelés fiziológiás ingerületvezetőrendszer-ingerléssel – múlt, jelen és jövő Open
Hagyományos pacemakerkezelésben részesülő betegek balkamra-funkciója a tartós jobb kamrai ingerlés következtében kialakuló elektromechanikai diszszinkrónia miatt romolhat, amelyet pacemaker indukálta cardiomyopathiának nevezünk. A tradicio…

A kardiális kontraktilitás modulációjával elért bal kamrai reverz remodelling egy dilatatív cardiomyopathiás betegben Open
Dilatatív cardiomyopathia talaján kialakult, súlyosan csökkent balkamra- (BK-) funkcióval (EF: 30%) járó szívelégtelenség miatt kardiáliskontraktilitás-modulátor (CCM) pacemakert implantáltunk egy 65 éves férfinak, keskeny QRS-komplex és o…

Az egyirányú blokk jelentősége pulmonalis vénaizoláció során Open
Esetünkben a pulmonalis vénaizoláció (PVI) során ritkán kialakuló unidirekcionális blokkot mutatunk be.A jobb oldali Esetünk egyedülálló példája egy szokatlan egyirányú blokknak

Not Every Potential Is What It Seems Open
A 73-year-old man with atrial fibrillation was referred for pulmonary vein (PV) isolation. Wide antral circumferential ablation was performed around the ipsilateral PVs. Following completion of the circles, adenosine test and pacing maneuv…

A case of unidirectional exit block during pulmonary vein isolation Open
We present a case of unidirectional exit block from a pulmonary vein (PV) during a pulmonary vein isolation procedure. Following circumferential antral applications around the right PVs, PV pacing showed capture without exit. Meanwhile cor…

Phased RF Ablation: Results and Concerns. Open
Treatment of atrial fibrillation (AF) with catheter ablation has proven to be a safe and effective treatment modality which is offered to an increasing number of patients in many centers. Pulmonary vein isolation (PVI) is an established co…

136-48: Unfavourable outcome after the upgrade of an implantable cardioverter defibrillator to cardiac resynchronization therapy Open
Background: Cardiac resynchronization therapy (CRT) improves survival in selected patients with heart failure (HF). As the potential survival benefit of CRT performed as an upgrade from a previously implanted cardioverter defibrillator (IC…

Positive correlation between sACE2 activity and NT-proBNP concentration. Open
Serum ACE2 activities were plotted as the function of NT Pro-Brain Natriuretic Peptide (NT-proBNP) concentrations in various study groups (healthy, n = 45, panel A, hypertensive, n = 239, panel B, HF - CRT before, n = 100, panel C, HF - CR…

Serum ACE2 activity correlates with left ventricular ejection fraction. Open
Serum ACE2 activities were plotted as a function of left ventricular ejection fraction (EF), in healthy people (healthy, n = 45, panel A), in patients with preserved EF (hypertensive, n = 239, panel B and in patients with severe reduction …

Hypothetic model for RAS regulation in heart failure. Open
Angiotensin I (AngI) is being converted to angiotensin II (AngII) by angiotensin converting enzyme (ACE). AngII is further metabolized to angiotensin 1–7 (Ang-(1–7)) by sACE2. AngII binds to and activate the type 1 AngII receptors (AT1R), …

Learning curve in circular multipolar phased radiofrequency ablation of atrial fibrillation Open
A learning curve effect was demonstrated in fluoroscopy times and in the number of RF applications but not in the acute success and in the long-term arrhythmia-free survival with circular multipolar RF ablations.
