Modified button technique for reattachment of coronary arteries in the aortic root replacement is reported. Anastomosis of the coronary buttons is performed from the inside of the composite valve graft previously including the coronary buttons in the composite valve graft. Reduced tension is present between coronary arteries and the composite valve graft once the heart is beating and the systemic pressure is increasing. In this way coronary buttons are reinforced directly by the composite aortic wall graft prosthesis. The coronary ostia are perfused with lower tension at the site of the coronary anastomoses. No bleeding from the suture line of the coronary buttons occurs using this new surgical approach.

Leadless pacemakers (LPs) are emerging options for bradyarrhythmias. However, extraction can be risky if the device is in an unfavorable position. We present a challenging case of a Nanostim LP (NLP) (Abbott Medical Inc.

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.

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.
