Association between delirium severity and prognosis following Transcatheter aortic valve implantation.

Background: Delirium is associated with patient prognosis after transcatheter aortic valve implantation (TAVI). However, the prognostic impact of subsyndromal delirium, described as an intermediate stage between delirium and normal cognition, is uncertain. The present study aimed to investigate the prognostic impact of delirium severity in patients undergoing TAVI.

Redo mitral valve replacement with annular reconstruction of left atrial dissection following mitral valve replacement for infective endocarditis: a case report.

Background: Left atrial dissection is a rare and occasionally fatal complication of cardiac surgery and is defined as the creation of a false chamber through a tear in the mitral valve annulus extending into the left atrial wall. Some patients are asymptomatic, while others present with various symptoms, such as chest pain, dyspnea, and even cardiac arrest. Although there is no established management for left atrial dissection, surgery should be considered in patients with hemodynamic disruption.

Impact of Cognitive Impairment on Long-Term Outcomes After Transcatheter Aortic Valve Implantation.

Background: Cognitive impairment assessed using the Mini-Mental Status Examination (MMSE) is associated with short-term mortality after transcatheter aortic valve implantation (TAVI). We assessed the long-term prognostic impact of cognitive impairment in patients with severe aortic stenosis post-TAVI.

Methods And Results: We enrolled 1,057 consecutive patients who underwent TAVI at the Kokura Memorial Hospital and prospectively assessed them using the MMSE.

Pulmonary Nocardiosis Due to Nocardia exalbida Infection Following Living-donor Liver Transplantation.

Nocardia exalbida, an uncommon Nocardia, was first identified in 2006. We herein report a 70-year-old man with pulmonary nocardiosis caused by N. exalbida after living-donor liver transplantation.

Comparing the Efficiency of Single versus Dual Ultrasonic Devices for Metallic Post Removal in Endodontic Retreatment: A Clinical Study.

Introduction: Ultrasonic vibration for metallic post removal seems to be a unanimous choice between endodontists and general practitioners for providing the best results and having the highest safety. This study compared the time required by ultrasonic vibration for removing metallic post (MP) when 1 or 2 ultrasonics devices are used.

Materials And Methods: One hundred and fifteen teeth with MPs from 105 patients, indicated for nonsurgical endodontic retreatment were divided into 2 groups according to the number of ultrasonic devices used (G1-1 device) and (G2-2 devices).
