Patients with severe aortic stenosis (AS) and left ventricular systolic dysfunction pose a significant challenge to the managing physician. Conventional pharmacological therapy for systolic heart failure has not been proven beneficial in this setting. Ivabradine, a selective current inhibitor, decreases the spontaneous firing rate of sinoatrial nodal cells, thereby reducing the heart rate, and has been shown to reduce a composite end-point of heart failure hospitalization and mortality in patients with impaired left ventricular function. Herein are reported details of the hemodynamic effects and clinical outcome of ivabradine treatment in an 86-year-old man with severe AS and severe left ventricular systolic function.

Anemia and Prognosis in Patients with Acute Venous Thromboembolism.
Thromb Haemost
January 2025
Department of General Internal Medicine, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland.
Background: Studies found an association between anemia and overall mortality and major bleeding (MB) in patients with acute venous thromboembolism (VTE), but whether anemia is causally related to death, bleeding, or recurrent VTE is uncertain.
Objectives: To explore the association between anemia at baseline and short-/long-term clinical outcomes in a prospective cohort of 928 patients with acute VTE.
Methods: We defined anemia as a hemoglobin <13 g/dL for men/< 12 g/dL for women.
Determining the QRS axis: visual estimation is equal to calculation.

Hannover Heart Rhythm Center, Department of Cardiology & Angiology, Hannover Medical School, Carl-Neuberg Str. 1, 30625, Hannover, Germany.
Background: The QRS axis of the electrocardiogram (ECG) is often considered in clinical practice, but its determination is frequently limited to a rough estimation, such as "normal", with left or right deviation, and superior or inferior in the case of premature ventricular complexes (PVCs). However, a more exact determination of the QRS axis may be warranted in certain scenarios, such as to determine the origin of PVCs more precisely, and is attainable by visual estimation using the hexaxial reference system.
Objectives: The aim of this study was to determine how well such an estimation of the QRS axis would correlate with the axis calculated by formulas.
Prediction of Radiation Therapy Induced Cardiovascular Toxicity from Pretreatment CT Images in Patients with Thoracic Malignancy via an Optimal Biomarker Approach.

January 2025
Medical Image Processing Group, 602 Goddard building, 3710 Hamilton Walk, Department of Radiology, University of Pennsylvania, Philadelphia, PA 19104 (M.L., M.A., J.K.U., Y.T., C.W., N.P., S.M., D.A.T.). Electronic address:
Rationale And Objectives: Cardiovascular toxicity is a well-known complication of thoracic radiation therapy (RT), leading to increased morbidity and mortality, but existing techniques to predict cardiovascular toxicity have limitations. Predictive biomarkers of cardiovascular toxicity may help to maximize patient outcomes.
Methods: The machine learning optimal biomarker (OBM) method was employed to predict development of cardiotoxicity (based on serial echocardiographic measurements of left ventricular ejection fraction and longitudinal strain) from computed tomography (CT) images in patients with thoracic malignancy undergoing RT.
Safety and effectiveness of pulsed field ablation for pulmonary vein isolation in atrial fibrillation patients: One-year single center experience.
Rev Port Cardiol
January 2025
Cardiology Department, Hospital Santa Cruz, Centro Hospitalar Lisboa Ocidental, Lisbon, Portugal.
Introduction And Objectives: Pulmonary vein (PV) isolation is one of the cornerstones of rhythm-control therapy for symptomatic atrial fibrillation (AF) patients. Pulsed field ablation (PFA) is a novel ablation modality that involves the application of electrical pulses causing cellular death, and it has preferential tissue specificity. In this study, we aimed to share a one-year single center experience of AF ablation with PFA.

Objectives: To prospectively evaluate clinical outcome and quality-of-life after surgical repair of ToF.
Methods: Single-centre, longitudinal cohort-study evaluating every decade 144 ToF patients who underwent surgical repair <15 years of age between 1968 and 1980.
