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.

Single coronary ostium and intramural coronary artery variations in patients with transposition of the great arteries significantly increase the mortality and morbidity after arterial switch operation (ASO). In these patients, the classic coronary button implantation may cause kinking or twisting of the coronary artery which can cause coronary insufficiency. This case series presents two patients, a 15-month-old girl with transposition of the great arteries and a 10-month-old boy with a Taussig-Bing anomaly.

Complete detachment of the aortic root following a Bentall procedure is an exceptionally rare complication. The vast majority of reported cases are secondary to prosthetic valve endocarditis or underlying vasculitis. Currently, the most reliable treatment for aortic root dehiscence-particularly in the context of prosthetic valve endocarditis-is repeat root replacement, typically via a second Bentall procedure or with the use of a homograft or allograft.

Clinical decision support (CDS) tools in electronic health records (EHRs) often face low uptake due to limited usability, workflow integration, and other implementation issues. We recently designed and implemented the STRATIFY-CDS tool, which calculates a validated risk-prediction model and recommends disposition for emergency department (ED) patients with acute heart failure. Despite applying human-centered design and implementation science strategies, initial utilization in the first 3 months of the STRATIFY-CDS tool was just 3%.

Patients presented for complicated redo surgery after previous aortic valve replacement with the indication for aortic root repair due to dilatation or aneurysm. In those cases where the prosthetic aortic valve is in good condition, a valve-sparing procedure might simplify the complicated surgery. The aim of this case series paper is to describe a technique and to show the results of repairing the aortic root without compromising the previously inserted, well-functioning mechanical aortic valve.

Background: An automated external defibrillator (AED) is a device that is used to prevent sudden death by delivering an electrical shock to restore the heart rhythm when experiencing cardiac arrest.
Objective: This study was performed to analyze the vibration and thermal changes experienced by an AED medical device when exposed to shocks caused by patients' reactions, vibrations from mobile and air ambulances, and heat changes due to the battery component on the circuit board.
Methods: Basically, AED is made from plastic, with the external parts containing the display, buttons, pad socket, and speaker, while the internal part entails the circuit boards comprising components such as resistors, capacitors, inductors, and integrated circuits, among others.
