Right bundle branch block can occasionally occur when a guide wire or catheter is inserted into the heart. An 83-year-old woman with preexisting left bundle branch block (LBBB) was diagnosed with paroxysmal atrial fibrillation (PAF) and severe mitral regurgitation (MR). The patient was started on amiodarone (100 mg/day) and bisoprolol (1.

Background: The Chiari network, a remnant of fetal anatomy, consists of a mesh-like structure within the right atrium. With advancements in cardiac interventions, complications associated with the Chiari network have increasingly been reported. However, there are few reports about guidewire or catheter entrapment in the Chiari network during the insertion of a dialysis catheter.

Introduction: Percutaneous left atrial appendage occlusion (LAAO) is traditionally performed under general anesthesia with trans-esophageal echocardiography guidance. Intracardiac echo (ICE)-guided LAAO closure is increasing in clinical use. The ICE catheter is crossed into LA via interatrial septum (IAS) after the septum is dilated with LAAO delivery sheath.

Although the Avalon Elite bi-caval dual lumen catheter for veno-venous extracorporeal membranous oxygenation (ECMO) has many advantages, it requires precise positioning and dislodgement is common. A 2-year-old male was placed on ECMO due to respiratory failure utilizing a 20 Fr Avalon Elite bi-caval dual lumen catheter (AEC). The AEC migrated twice with unsuccessful repositioning using the classic manual manipulations.

In this study, we investigated the feasibility of predicting the performance of a specific guidewire in terms of its ability to cover a lesion cap surface and apply force to the lesion for a given patient's vessel anatomy. The aim of this research was to provide information that could be used to plan occlusion crossings and peripheral revascularization procedures preoperatively in a way that reduces the risk of potential intraoperative complications and increases the likelihood of success. We used finite element (FE) analysis to simulate the interaction between the guidewire and a model of a tortuous vessel, and we used this simulation to predict the reachable workspace and deliverable forces of the device for various entry positions and angles.
