Mobile Thrombus Observed Around an Impella Device.

An Impella device (Abiomed, Inc., Danvers, Massachusetts, United States) is a useful percutaneous left ventricular assist device for patients with cardiogenic shock. However, there are cases in which patients are unable to escape cardiogenic shock and become Impella-dependent.

Successful conservative management of advanced pyogenic sternoclavicular joint arthritis with osteomyelitis and pulmonary infiltration: a case report.

Background: Sternoclavicular joint arthritis is a rare condition that poses considerable diagnostic and therapeutic challenges, leading to severe complications and a high mortality rate. Although surgical interventions are often considered necessary for advanced cases, some reports have suggested that conservative management with antibiotic therapy can be effective in certain cases. However, to our knowledge, there are no reports of successful conservative treatment in cases exhibiting aggressive spread.

Clinical efficacy of TEVAR utilizing fenestrated stent-grafts for zone 0 in an elderly frail patient with giant aortic arch aneurysm.

Introduction And Importance: Elderly and frail patients with thoracic aortic aneurysms (TAAs) near to origins of cervical arteries present facing challenges with aortic arch replacement with cardiopulmonary bypass, and traditional tube-type stent-grafts are also inadequate for transcatheter endovascular aortic repair (TEVAR). Thus, necessitating precise treatment with fenestrated stent-grafts from zone 0. This approach is crucial for achieving favorable postoperative outcomes without compromising activities of daily living (ADL).

Bioprosthetic Valve Deterioration: Accumulation of Circulating Proteins and Macrophages in the Valve Interstitium.

Histologic evaluations revealed excessive accumulations of macrophages and absence of fibroblastic interstitial cells in explanted bioprosthetic valves. Comprehensive gene and protein expression analysis and histology unveiled an accumulation of fibrinogen and plasminogen, an activator of infiltrated macrophages, from degenerated valve surfaces in the interstitial spaces. These pathologies were completely reproduced in a goat model replaced with an autologous pericardium-derived aortic valve.

[Active Utilization of Robot-assisted Cardiac Surgery in Educational Institution].

Minimally invasive cardiac surgery( MICS) has emerged in 1990s. Nowadays, MICS via mini thoracotomy became popular for valvular heart disease. Robot-assisted cardiac surgery was introduced with extension to MICS.

Mediastinal and Hilar Lymph Node Metastases from Renal Cell Carcinoma with Concomitant Lung Carcinoma: A Rare Case with Unique Diagnostic Challenges.

A 75-year-old man presented to our hospital 1 year after partial renal resection for clear cell carcinoma. A right lower lobe lung nodule noted at the time of surgery had increased to 3.0 cm in diameter and was confirmed as squamous cell lung carcinoma by bronchoscopic cytology.

Unique Angiogenesis From Cardiac Arterioles During Pericardial Adhesion Formation.

Objectives: The molecular mechanisms underlying post-operative pericardial adhesions remain poorly understood. We aimed to unveil the temporal molecular and cellular mechanisms underlying tissue dynamics during adhesion formation, including inflammation, angiogenesis, and fibrosis.

Methods And Results: We visualized cell-based tissue dynamics during pericardial adhesion using histological evaluations.

Use of uniportal video-assisted thoracic surgery combined with a posterior approach to resect a dumbbell-shaped mediastinal granular cell tumor: A case report.

Introduction: A dumbbell-shaped mediastinal granular cell tumor has never been reported, and there have been no reports of dumbbell-shaped tumors resected with a combination of uniportal video-assisted thoracic surgery and the posterior approach.

Presentation Of Case: An 18-year-old woman was diagnosed with a mediastinal dumbbell-shaped granular cell tumor by computed tomography. Complete resection was achieved via a posterior approach combined with the uniportal video-assisted thoracic surgery.

Hypoxic Culture Maintains Cell Growth of the Primary Human Valve Interstitial Cells with Stemness.

The characterization of aortic valve interstitial cells (VICs) cultured under optimal conditions is essential for understanding the molecular mechanisms underlying aortic valve stenosis. Here, we propose 2% hypoxia as an optimum VIC culture condition. Leaflets harvested from patients with aortic valve regurgitation were digested using collagenase and VICs were cultured under the 2% hypoxic condition.

Contemporary patterns of the management of truncus arteriosus (primary versus staged repair): outcomes from the Japanese National Cardiovascular Database.

Objectives: Although primary repair in early infancy has for decades been the prevalent strategy for management of truncus arteriosus (TA), recent concerns about the levels of morbidity and mortality have led to consideration of a staged surgical approach. Our goal was to describe recent patterns of management, to characterize patients who underwent primary or staged repair and to evaluate risk factors associated with operative mortality in a contemporary multicentre cohort.

Methods: In the Japanese Cardiovascular Surgery Database, we identified all cases of TA undergoing an initial surgical procedure from 2008 to 2018.

Quality of life after partial lung resection with uniportal versus 3-port video-assisted thoracoscopic surgery: a prospective randomized controlled study.

Purpose: The effect of uniportal video-assisted thoracoscopic surgery (uni-VATS) versus that of conventional VATS on postoperative quality of life (QOL) is unclear. This prospective randomized controlled study compared uni-VATS and conventional 3-port VATS in terms of QOL and patient satisfaction.

Methods: The subjects of this study were 84 patients with pulmonary nodules or bullous formation, randomized to undergo uniportal or conventional 3-port video-assisted thoracoscopic partial lung resection.

Usefulness of contrast computed tomography for diagnosing left ventricular thrombus before impella insertion.

The Impella (Abiomed, Danvers, MA, USA) is a novel percutaneous heart pump device for left ventricular (LV) assistance; however, LV thrombus is a notable contraindication for this device. Contrast computed tomography assessment is useful for detecting LV thrombus and preventing thromboembolism in patients recommended for Impella use. < The Impella (Abiomed, Danvers, MA, USA) is a heart pump device which aspirates blood from a left ventricular (LV) cavity and ejects it into an ascending aorta.

A case report of thrombotic complete obstruction of the ascending aorta as a complication of Venoarterial extracorporeal membrane oxygenation support: steps to prevent thrombosis.

Background: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is an essential device in the field of emergency and intensive-care medicine. However, long-term use of VA-ECMO has various severe complications, including thrombosis.

Case Presentation: A 60-year-old man underwent his third aortic root replacement using a homograft because of infectious endocarditis.

[Minimally Invasive Cardiac Surgery for Valvular Heart Disease in Japan;Past and Present].

Minimally invasive cardiac surgery (MICS) through partial sternotomy or parastenal incision was introduced for valvular heart disease in 1990s, it has gradually faded because it was somehow challenging without standardized manner or positive merits for the patients. Conversely, MICS via mini-thoracotomy has been started for mostly the patients undergoing mitral valve repair in 2000s, the number of MICS through mini-thoracotomy cases has increased progressively with the supports by academic societies and a national registry database system. Some enthusiasm for less invasiveness fashion oriented smaller skin incision and endoscopic procedures.
