Left atrial appendage closure aims to eliminate the stasis component of Virchow triad by eliminating a cul-de-sac that favors thrombosis, particularly when atrial contractility becomes inefficient, such as in atrial fibrillation. Left atrial appendage closure devices have a common objective of sealing the appendage completely, with device stability and avoidance of device thrombosis. Two main device designs have been used to perform left atrial appendage closure: those that use a pacifier design (lobe + disk) and those that use a plug (single lobe) design. This review highlights the potential features and benefits of the single-lobe devices.

Background: Although the method of autocalibration or calibration based on catheter diameters was proposed for fluoroscopic measurement during percutaneous left atrial appendage occlusion (LAAO), it may be imprecise and lead to mismeasurement. We sought to investigate whether the utilization of the surface steel ball calibration (SSBC) method under fluoroscopy could facilitate the fluoroscopic measurement of the post-implanted WATCHMAN device (Boston Scientific Corporation, Natick, MA, USA) in LAAO.

Methods: This retrospective study included 97 consecutive patients who underwent percutaneous LAAO with the WATCHMAN device.

Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous entity including patients with different phenotypes of near normal, normal, and supernormal left ventricular (LV) function.

Objectives: To assess the value of resting LV elastance (also known as force) with transthoracic echocardiography (TTE) to identify HFpEF phenotypes.

Methods: In a prospective, observational, multicenter study, 2380 HFpEF patients were recruited from July 2016 to May 2024.

This case report describes a surgical treatment combined with interventional therapy for a patient with refractory hemodialysis access combined with catheter-related right atrial thrombosis (CRAT). During surgery, an artificial graft was established from the left brachiocephalic vein to the right atrium and the right atrial thrombus was removed. After the operation, the tunneled cuffed catheter (TCC) was replaced with digital subtraction angiography (DSA).

An atrial septal defect (ASD) is a common congenital heart anomaly that results in irregular blood flow between the systemic and pulmonary circulations due to an opening in the atrial septum. Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.
