Aim: This study was conducted to investigate the relationship between the hospitalizations and backgrounds of patients with coronavirus disease 2019 to identify specific risk factors.

Methods: This retrospective study used health observation records to analyze the relationship between certain risk factors and the subsequent hospitalization of 321 patients who were discharged from a residential care facility between January 16 and February 8, 2021. The usefulness of a hospitalization prediction score, created based on the presence of comorbidities and sex, was examined.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has caused great disruptions in education and healthcare systems. However, before the COVID-19 pandemic, Hyogo Prefecture did not have a centralized system for sharing information among hospitals, public healthcare centers, the government, fire departments, and medical associations. In March 2021, we used Slack,® an enterprise social network, to invite people from hospitals, healthcare centers, the government, fire departments, and medical associations to join our workspace.

Background: Studies describing the effectiveness of extracorporeal cardiopulmonary resuscitation (ECPR) for peripartum cardiopulmonary arrest are lacking.

Case Presentation: A 39-year-old woman underwent elective cesarean section. Right after surgery, she fell into a cardiac arrest and was promptly transferred to our institute by ambulance.

Background: Initial electrocardiogram (ECG) rhythm is a predictor of outcomes in out-of-hospital cardiac arrest (OHCA) in patients receiving extracorporeal cardiopulmonary resuscitation (ECPR). However, ECG rhythm often changes before ECPR, and the consequence of this change remains unclear. This study aimed to assess the relationship between the conversion of ECG rhythm from initial shockable rhythm before ECPR and mortality.

Aim: To investigate the clinical features of traumatic asphyxia, specifically the presence of cardiac arrest and therapeutic efficacy. This review will be useful for future emergencies.

Methods: Sixteen traumatic asphyxia cases from our hospital between April 2007 and March 2019 were reviewed and divided into three groups: those experiencing cardiac arrest at the time of rescue (group A, six cases), those experiencing cardiac arrest after rescue (group B, five cases), and those who did not experience cardiac arrest (group C, five cases).

We report a case of vascular injury caused by a multi-lumen catheter for CRRT inserted through left jugular vein. Diagnosis was delayed because CRRT could be continued. Clinicians should be aware of potential vascular complications associated with the wrong placement of multi-lumen catheters even if blood flow continues without difficulty.

Background: The focused assessment with sonography for trauma (FAST) examination is helpful for the identification of pericardial effusion in trauma. However, in a cardiac rupture with a pericardial perforation, pericardial effusion is not always detected by FAST. We experienced the case that FAST and enhanced CT failed to detect pericardial effusion.

A 74-year-old woman with exertional angina was diagnosed with occlusion of the left coronary ostium associated with a rudimentary aortic valve cusp. A transesophageal echocardiogram, a multi-detector computed tomographic scan, and a coronary angiographic scan revealed the rudimentary aortic cusp covering the small left coronary aortic sinus leading to occlusion of the ostium of the left coronary artery, despite the intact coronary arteries. After excision of the rudimentary left coronary cusp, the left coronary ostium appeared intact.

We describe a 16-year-old suffering from the dilated phase of mid-ventricular obstructive hypertrophic cardiomyopathy with end-stage heart failure. Her plasma type-B natriuretic peptide level exceeded 8000 pg/ml, and she refused heart transplantation. She underwent an apicoaortic valved conduit as an alternative to the heart transplant procedure.

Background And Aim Of The Study: Surgical results after aortic valve repair in patients with aortic regurgitation (AR) of tricuspid valve morphology and with no evidence of aortic root disease have not yet been clarified.

Methods: Between January 1994 and June 2001, aortic valve repair was performed in 40 patients (eight females, 32 males; mean age 61.0 +/- 10.

The aim of this study was to determine the most efficient design of composite grafts and clarify the technical feasibility rate of composite grafting using internal thoracic artery exclusively in patients undergoing triple-vessel revascularization. Retrospective analysis of 104 consecutive patients was carried out. An in situ left internal thoracic artery graft for the left anterior descending artery area, with attachment of the right internal thoracic artery to the side of the left internal thoracic artery to revascularize the circumflex and right coronary vessels, was the most efficient graft design.

Background And Aim Of The Study: A recently developed technique of aortic annuloplasty, together with immediate postoperative results, are described.

Methods: Between June 1998 and October 2000, 26 patients (22 men, four women; mean age 59 years) with chronic dominant aortic regurgitation (AR) underwent aortic valve repair in which subvalvular circular annuloplasty was used. A concomitant repair technique was performed in all patients.
