Here, we present a case report detailing a pseudoaneurysm of the coronary button due to aortic remodeling that occurred 2 years after aortic root replacement. The patient was referred to our hospital with a diagnosis of left coronary artery pseudoaneurysm. Intraoperative findings revealed substantially loosened sutures in both the left and right coronary arteries with bleeding. Specifically, the left coronary artery was detached at the 6-9 o'clock positions. The operation was concluded with ligation of the loose suture and addition of a new suture. Chronic dissection thickened the aortic wall of the coronary artery ostium in the initial Bentall operation, whereas the sutured coronary button in this operation exhibited a normal arterial wall without a thickened dissected intima. This suggests that aortic wall remodelling of the coronary ostium leads to suture loosening and subsequent haemorrhage. Aortic wall remodeling may lead to bleeding or pseudoaneurysms during the remote period.

Worldwide Chronic Retrieval Experience of Helix-Fixation Leadless Cardiac Pacemakers.
J Am Coll Cardiol
December 2024
Icahn School of Medicine at Mount Sinai, New York, New York, USA.
Background: The growing use of leadless pacemaker (LP) technology requires safe and effective solutions for retrieving and removing these devices over the long term.
Objectives: This study sought to evaluate retrieval and removal of an active helix-fixation LP studied in worldwide regulatory clinical trials.
Methods: Subjects enrolled in the LEADLESS II phase 1 investigational device exemption, LEADLESS Observational, or LEADLESS Japan trials with an attempted LP retrieval at least 6 weeks postimplantation were included.
Background: Foreign body (coins, magnets, button batteries, and metallic foreign bodies) ingestion is common and causes significant morbidity and mortality in children aged six months to three years. Endoscopic removal of swallowed foreign substances is widely accepted, but sedation and general anesthesia may be required to alleviate pain and anxiety during the procedure. Dexmedetomidine is used as a sedative, hypnotic, anxiolytic, and analgesic.

Innovations (Phila)
December 2024
Division of Cardiac Surgery, Western University, London, ON, Canada.
Aortic root reconstruction operations have undergone substantial evolution with technical modifications, expanding indications, and the need for increasingly complex decision-making. The purpose of this state-of-the-art review is to detail our approach to contemporary aortic root reconstruction operations. First, we review the evolution of root reconstruction procedures over the years and discuss the approach to the aortic root patient for lifetime management of aneurysm and valvular disease in the modern context of management options.

Article Synopsis
- - Hemorrhage is the main cause of preventable death in trauma situations, leading to military and civilian advancements in medical practices, particularly through the use of tourniquets to manage extremity bleeding and save lives.
- - While tourniquets have significantly decreased deaths from bleeding in military settings, noncompressible hemorrhage still poses a major risk, especially before patients receive definitive medical care.
- - The study explores using a small, disposable pressure monitor during resuscitative endovascular balloon occlusion of the aorta (REBOA) to enhance blood pressure monitoring, facilitate better resuscitation practices, and reduce the need for blood products in extreme environments.
Gastrojejunostomy junction perforation resulting from Dobhoff tube insertion in a patient with a history of Roux-en-Y surgery: a case report.
J Med Case Rep
October 2024
Department of Internal Medicine, Creighton University, Omaha, NE, USA.
Background: Gastrojejunostomy junction perforation is a rare yet critical complication associated with enteral tube placement, presenting unique challenges in patients with a history of Roux-en-Y gastric bypass surgery.
Case Presentation: A 63-year-old white female with a complex medical history, including heart failure, atrial fibrillation, stage 4 chronic kidney disease, and prior Roux-en-Y gastric bypass surgery in 2015, experienced a significant decline in her health. She was discharged to a skilled nursing facility after a fall but deteriorated rapidly in the 2 weeks before admission.
