Does Age Impact Safety and Efficacy During Pulse-Field Ablation for Atrial Fibrillation?

Background: There is no evidence evaluating efficiency, effectiveness, and safety outcomes in older patients in the context of pulsed-field ablation technology for the ablation of atrial fibrillation. We aimed to compare safety, efficacy, and acute and long-term outcomes of pulsed-field ablation in older patients (≥75 years) with younger ones.

Methods: We enrolled consecutive patients who had undergone atrial fibrillation ablation with the pulsed-field ablation FARAPULSE system (Boston Scientific) at 15 centers.

Temperature and ST-segment morphology remote monitoring: new perspectives for implantable cardiac monitors in Brugada syndrome.

Introduction: Patients with Brugada syndrome (BrS) face an increased risk of ventricular arrhythmias and sudden cardiac death. Implantable cardiac monitors (ICMs) have emerged as effective tools for detecting arrhythmias in BrS. Technological advancements, including temperature sensors and improved subcutaneous electrocardiogram (subECG) signal quality, hold promise for further enhancing their utility in this population.

Predicting ventricular arrhythmia inducibility in ajmaline-induced Brugada type I pattern: Validation of the dST-Tiso interval.

Introduction: The dST-Tiso is a newly proposed electrocardiographic (ECG) marker during Brugada (BrS) type I pattern, that predicts the likelihood of ventricular arrhythmia (VA) inducibility in patients with ajmaline-induced pattern. The objective of this study was to validate the effectiveness of this criterion using an independent data set.

Methods: Consecutive patients exhibiting a BrS type I ECG pattern following ajmaline administration underwent programmed ventricular stimulation (PVS).

Investigating Deep Sedation With Intravenous Ketamine in Spontaneous Respiration During Pulsed-Field Ablation.

Objectives: The authors report their experience of a protocol for deep sedation with ketamine in spontaneous respiration during the pulsed-field ablation (PFA) of atrial fibrillation (AF).

Design: Observational, prospective, nonrandomized fashion.

Setting: Single-center hospitalized patients.

Lung Ultrasound, Echocardiography, and Fluid Challenge for the Differential Diagnosis of Pulmonary Hypertension.

Objectives: The differential diagnosis between pulmonary arterial hypertension (PAH) and postcapillary pulmonary hypertension (PH) in heart failure with preserved ejection fraction (HFpEF) is sometimes difficult despite guidelines-derived standardized step-by-step diagnostic algorithms. We therefore explored the added value of lung ultrasound to a previously validated echocardiographic score of right heart catheterization measurements.

Methods: Patients referred for PH underwent a right heart catheterization, echocardiography, and lung ultrasound before and after rapid infusion of 7 mL/kg of saline.

Coronary microvascular dysfunction affects left ventricular global longitudinal strain response to dipyridamole stress echocardiography: a pilot study.

The aim is to investigate, by means of speckle tracking echocardiography, left ventricular (LV) contractile function at rest and during dipyridamole stress in patients with coronary microvascular dysfunction (CMD). 59 patients (39% women, mean age 65.6 ± 6.

Echocardiographic probability of pulmonary hypertension: a validation study.

Background: According to current guidelines, the diagnosis of pulmonary hypertension (PH) relies on echocardiographic probability followed by right heart catheterisation (RHC). How echocardiography predicts PH recently redefined by mean pulmonary arterial pressure (mPAP) >20 mmHg instead of ≥25 mmHg and pulmonary vascular disease defined by pulmonary vascular resistance (PVR) ≥3 or >2 WU has not been established.

Methods: A total of 278 patients referred for PH underwent comprehensive echocardiography followed by RHC.

Incremental value of compression ultrasound sonography in the emergency department.

The quick evaluation of venous thromboembolism is a key point of modern medicine since the delayed diagnosis is associated with a worse prognosis. Venous ultrasound (VU) is a sensitive and rapidly performed test in cases of suspected deep venous thrombosis. Various protocols have been proposed for its execution, such as the study of the whole deep venous circulation of the lower limb or the analysis of the femoral-popliteal area.

[Pulmonary arterial hypertension or heart failure with preserved ejection fraction? Beyond heart catheterization: a roadmap for challenging cases].

The cause of dyspnea may remain uncertain even after a complete non-invasive clinical workup, and a right heart catheterization is performed to achieve a definitive diagnosis. Although pulmonary artery wedge pressure (PAWP) is key for the differential diagnosis between pulmonary arterial hypertension (PAH) and heart failure with preserved ejection fraction (HFpEF), the diagnosis may be challenging because PAWP may be normal after diuretic administration in HFpEF patients on optimal medical therapy. In order to avoid misdiagnosis, building a pre-test probability of pre- or post-capillary pulmonary hypertension is crucial.

The Pharmacological Approach to Oncologic Patients with Acute Coronary Syndrome.

Among acute coronary syndrome (ACS) patients, 15% have concomitant cancer, especially in the first 6 months after their diagnosis, as well as in advanced metastatic stages. Lung, gastric, and pancreatic cancers are the most frequent malignancies associated with ACS. Chemotherapy and radiotherapy exert prothrombotic, vasospastic, and proinflammatory actions.
