Cardiac Involvement in Thoracic Lymphoma.

This case highlights the role of cardiac imaging in detecting the evolution of cardiac involvement during thoracic lymphoma and the importance of optimal chemotherapy, which leads to a rapid improvement of the cardiac dysfunction, without the need for cardiac pharmacotherapy.

Right Heart Obstructive Disease due to Tumoral Infiltration.

Cardiac tumor infiltration can present with right heart obstruction and peripheral congestion, mimicking other causes of heart failure. Early recognition through imaging is crucial, as surgical intervention may be lifesaving in select cases.

Spontaneous Resolution of Ventricular Pre-Excitation During Childhood: A Retrospective Study.

Ventricular pre-excitation (VP) increases the risk of sudden cardiac death among children. While transcatheter ablation could potentially be therapeutic, it is not without risk, especially in smaller children. Accessory pathways (APs) may spontaneously lose anterograde conduction properties over time, making invasive treatment unnecessary.

Left Ventricular Thrombosis in Ischemic and Non-Ischemic Cardiomyopathies: Focus on Evidence-Based Treatment.

Left ventricular thrombosis (LVT) is one of the most feared complications of both ischemic and non-ischemic cardiopathy, and despite its incidence having decreased over the years (mostly due to novel reperfusion therapies in acute coronary syndromes), it is still not negligible. If transthoracic echocardiography, possibly with the adjunction of echo contrast, represents the cornerstone in LVT diagnosis, sometimes it is found to be nonconclusive and advanced cardiovascular imaging, namely cardiac magnetic resonance, needs to be performed to fully exclude intraventricular masses or to better characterize them. Vitamin K antagonists always represented the anticoagulant of choice for the treatment of LVT; however, the recent spread of direct oral anticoagulants (DOACs) pushed clinicians to adopt them also in this setting despite the absence of robust evidence in their favor.

Catheter Ablation of Atrial Fibrillation in Patients with Heart Failure: Focus on the Latest Clinical Evidence.

Atrial fibrillation and heart failure are two common cardiovascular conditions that frequently coexist, and it has been widely demonstrated that in patients with chronic heart failure, atrial fibrillation is associated with a significant increase in the risk of all-cause death and all-cause hospitalization. Nevertheless, there is no unanimous consensus in the literature on how to approach this category of patients and which therapeutic strategy (rhythm control or frequency control) is the most favorable in terms of prognosis; moreover, there is still a lack of data comparing the different ablative techniques of atrial fibrillation in terms of efficacy, and many of the current trials do not consider current ablative techniques such as high-power short-duration ablation index protocol for radiofrequency pulmonary vein isolation. Eventually, while several RCTs have widely proved that in patients with heart failure with reduced ejection fraction, ablation of atrial fibrillation is superior to medical therapy alone, there is no consensus regarding those with preserved ejection fraction.

Peri-Procedural Management of Direct-Acting Oral Anticoagulants (DOACs) in Transcatheter Miniaturized Leadless Pacemaker Implantation.

Introduction: Data on peri-operative management of direct-acting oral anticoagulants (DOACs) during transcatheter pacing leadless system (TPS) implantations remain limited. This study aimed to evaluate a standardized DOAC management regime consisting of interruption of a single dose prior to implantation and reinitiation within 6-24 h; also, patient clinical characteristics associated with this approach were identified.

Method: Consecutive patients undergoing standard TPS implantation procedures from two Swiss tertiary centers were included.

Role of genetic testing in young patients with idiopathic atrioventricular conduction disease.

Aims: To investigate the role of genetic testing in patients with idiopathic atrioventricular conduction disease requiring pacemaker (PM) implantation before the age of 50 years.

Methods And Results: All consecutive PM implantations in Southern Switzerland between 2010 and 2019 were evaluated. Inclusion criteria were: (i) age at the time of PM implantation: < 50 years; (ii) atrioventricular block (AVB) of unknown aetiology.

Serum uric acid in patients with ST-segment elevation myocardial infarction: An innocent bystander or leading actor?

Elevated serum uric acid (SUA) levels have been associated with several cardiovascular risk factors and the progression of coronary artery disease. In the setting of acute myocardial infarction, increasing evidence suggests that high SUA levels could be related to adverse outcomes. Interestingly elevated SUA levels have been linked to endothelial dysfunction, inflammation and oxidative stress.

Catheter Ablation of Atrial Fibrillation in Patients with Previous Lobectomy or Partial Lung Resection: Long-Term Results of an International Multicenter Study.

Introduction: Data regarding the efficacy of catheter ablation in patients with atrial fibrillation (AF) and patients' previous history of pulmonary lobectomy/pneumonectomy are scanty. We sought to evaluate the efficacy and long-term follow-up of catheter ablation in this highly selected group of patients.

Material And Methods: Twenty consecutive patients (8 females, 40%; median age 65.

Perioperative Management of Patients with Cardiac Implantable Electronic Devices and Utility of Magnet Application.

With the demographic evolution of the population, patients undergoing surgery today are older and have an increasing number of sometimes complex comorbidities. Cardiac implantable electronic devices (CIED) are also getting more and more complex with very sophisticated programming algorithms. It may be generally assumed that magnet application reverts pacing to an asynchronous mode in pacemakers and disables tachycardia detection/therapy in internal cardioverter-defibrillators.

Extracorporeal veno-venous ultrafiltration in patients with acute heart failure.

Hospitalization for congestive heart failure represents a growing burden for health care systems. Heart failure is characterized by extracellular fluid overload and loop diuretics have been for decades the cornerstone of therapy in these patients. However, extensive use of intra-venous diuretics is characterised by several limitations: risk of worsening renal function and electrolyte imbalance, symptomatic hypotension and development of diuretic resistance.

Acute kidney injury and in-hospital mortality in patients with ST-elevation myocardial infarction of different age groups.

Background: Acute kidney injury (AKI) is a well-known complication of ST-elevation acute myocardial infarction (STEMI) with an adverse impact on prognosis. Since AKI develops more frequently in elderly patients, we hypothesized that its higher incidence in older STEMI patients might explain their increased in-hospital mortality. We assessed the relationship between AKI and in-hospital mortality in patients with STEMI of different age groups.

Long-term outcome of catheter ablation for atrial fibrillation in patients with severe left atrial enlargement and reduced left ventricular ejection fraction.

Aims: Data regarding the efficacy of catheter ablation in heart failure patients with severely dilated left atrium and reduced left ventricular ejection fraction (LVEF) are scanty. We sought to assess the efficacy of catheter ablation in patients with reduced LVEF and severe left atrial (LA) enlargement, and to compare it to those patients with preserved left ventricular function and equally dilated left atrium.

Methods And Results: Three patient groups with paroxysmal or persistent atrial fibrillation (AF) undergoing a first pulmonary vein isolation (PVI) were considered: Group 1 included patients with normal or mildly abnormal LA volume (≤41 mL/m2) and normal LVEF; Group 2 included patients with severe LA enlargement (>48 mL/m2) and normal LVEF; and Group 3 included patients with severe LA enlargement and reduced LVEF.

Impact of SMART Pass filter in patients with ajmaline-induced Brugada syndrome and subcutaneous implantable cardioverter-defibrillator eligibility failure: results from a prospective multicentre study.

Aims: Ajmaline challenge can unmask subcutaneous implantable cardioverter-defibrillator (S-ICD) screening failure in patients with Brugada syndrome (BrS) and non-diagnostic baseline electrocardiogram (ECG). The efficacy of the SMART Pass (SP) filter, a high-pass filter designed to reduce cardiac oversensing (while maintaining an appropriate sensing margin), has not yet been assessed in patients with BrS. The aim of this prospective multicentre study was to investigate the effect of the SP filter on dynamic Brugada ECG changes evoked by ajmaline and to assess its value in reducing S-ICD screening failure in patients with drug-induced Brugada ECGs.

ST-Segment Elevation Acute Myocardial Infarction Complicated by Cardiogenic Shock: Early Predictors of Very Long-Term Mortality.

Background: Cardiogenic shock (CS) is the leading cause of in-hospital mortality in ST-segment elevation myocardial infarction (STEMI). Only limited data are available on the long-term outcome of STEMI patients with CS undergoing contemporary treatment. We aimed to investigate long-term mortality and its predictors in STEMI patients with CS and to develop a risk score for long-term mortality prediction.

Elevated serum uric acid is a predictor of contrast associated acute kidney injury in patient with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Background: Contrast associated-acute kidney injury (CA-AKI) has been associated with adverse outcomes after ST-segment elevation myocardial infarction (STEMI). However, early markers of CA-AKI are still needed to improve risk stratification. We investigated the association between elevated serum uric acid (eSUA) and CA-AKI in patients with STEMI treated with primary percutaneous coronary intervention (pPCI).

Transcatheter mitral valve repair with MitraClip in patients with pulmonary hypertension: hemodynamic and prognostic perspectives.

Transcatheter mitral valve repair with MitraClip has emerged as a possible therapeutic option for patients with severe mitral regurgitation (MR) with high risk for surgical valve repair. MitraClip intervention has demonstrated to improve haemodynamics and clinical outcomes in selected patients in observational and randomized studies. Preoperative pulmonary hypertension (PH) is known to affect prognosis in patients undergoing surgical mitral valve intervention.

De Winter Pattern Caused by a Large Diagonal Branch Culprit Lesion.

A 70-year-old man was referred to the emergency department for an episode of ongoing chest pain during physical activity. Urgent coronary angiogram revealed a 75% stenosis in the left anterior descending coronary artery and a total occlusion of a large diagonal branch. Both stenoses were treated successfully with percutaneous coronary intervention.

A Primary Prevention Clinical Risk Score Model for Patients With Brugada Syndrome (BRUGADA-RISK).

Objectives: The goal of this study was to develop a risk score model for patients with Brugada syndrome (BrS).

Background: Risk stratification in BrS is a significant challenge due to the low event rates and conflicting evidence.

Methods: A multicenter international cohort of patients with BrS and no previous cardiac arrest was used to evaluate the role of 16 proposed clinical or electrocardiogram (ECG) markers in predicting ventricular arrhythmias (VAs)/sudden cardiac death (SCD) during follow-up.
