Misdiagnosis of a Massive Pulmonary Thromboembolism in A Patient With Dextrocardia and a Pacemaker.

Pulmonary thromboembolism (PTE) is the third most common cause of acute cardiovascular disease, which can lead to high morbidity and mortality if left untreated. Anatomical and electrophysiological variations and obesity may complicate timely diagnosis and delay required management. While computed tomography pulmonary angiography (CTPA) remains the most accurate diagnostic tool, initial assessments using electrocardiography (ECG) or echocardiography can be helpful in early suspicion.

Introduction: Focal atrial tachycardia (FAT) is predominant in the pediatric population. Recent research has identified cases of sustained FAT originating from the interatrial septum (IAS); a subset of cases presents a unique challenge, with foci originating from the peri-patent foramen ovale (peri-PFO), requiring specialized management during catheter ablation. Here, we present a rare case of peri-PFO-associated FAT that resulted in tachycardia-related cardiomyopathy and propose a comprehensive multipath joint strategy for the successful treatment of PFO-associated FAT.

Background: The antiarrhythmic effect of melatonin(MLT) has been demonstrated in several studies; however, this hypothesis has recently been contested. Our research seeks to determine if exogenous MLT supplementation can reduce atrial fibrillation (AF) susceptibility due to sleep deprivation (SD) by addressing Ca mishandling and atrial mitochondrial oxidative stress.
Methods: Adult rats received daily MLT or vehicle injections and were exposed to a modified water tank.
Diagnosis of atrial cardiomyopathy: from the electrocardiogram to the new opportunities with multimodality imaging.

Atrial cardiomyopathy (AC) has been defined by the European Heart Rhythm Association as "Any complex of structural, architectural, contractile, or electrophysiologic changes in the atria with the potential to produce clinically relevant manifestations".1 The left atrium (LA) plays a key role in maintaining normal cardiac function; in fact atrial dysfunction has emerged as an essential determinant of outcomes in different clinical scenarios, such as valvular diseases, heart failure (HF), coronary artery disease (CAD) and atrial fibrillation (AF). A comprehensive evaluation, both anatomical and functional, is routinely performed in cardiac imaging laboratories.

Purpose Of The Review: This review examines the role of vascular access and closure management in cardiac electrophysiology (EP) procedures, emphasising their impact on patient outcomes and safety. It synthesises current evidence and highlights advancements, challenges, and opportunities in this critical area of EP practice.
Recent Findings: Ultrasound-guided vascular access has significantly reduced complications and improved success rates compared to traditional methods.
