SARS-CoV-2 Fulminant Myocarditis.

An 18-year-old male without prior medical history developed fulminant myocarditis concomitant to severe COVID-19 pneumonia, which was confirmed using serial cardiac magnetic resonance. This may have important diagnostic, monitoring, and pathogenic implications. ().

An unidentified endobronchial object in a newly transplanted lung.

A fiberoptic examination is recommended at the end of lung transplantation for bronchial toilet and to check the bronchial anastomoses. This procedure permitted detection of a 10 × 4-mm piece of plastic of unknown origin in the left lingular bronchus and suggests that bronchoscopy should be performed before implanting the transplanted lung.

Intraoperative occurrence of a pneumopericardium during double-lung transplantation.

Pneumopericardium is rare and has been reported secondary to chest trauma. We report a case of tension pneumopericardium occurring during double-lung transplantation, where intraoperative transoesophageal echocardiography first showed a hypokinetic left ventricle and a few minutes later a compression of its anterolateral portion due to pneumopericardium. Although the pericardium was opened, left ventricular function remained depressed, necessitating extracorporeal membrane oxygenation, which was withdrawn after 48 h of assistance when left ventricular function had recovered.

Transesophageal and contact ultrasound echographic assessments of pulmonary vessels in bilateral lung transplantation.

Background: Intraoperative transesophageal echocardiographic visualization of the vascular anastomosis of lung grafts can be difficult. The goal of this prospective study was to compare intraoperative transesophageal echocardiography and contact ultrasound.

Methods: Vessel imaging and Doppler analysis obtained before chest closure by both techniques were compared in 18 bilateral lung transplant recipients.

Factors associated with early graft dysfunction in cystic fibrosis patients receiving primary bilateral lung transplantation.

Objectives: Primary graft dysfunction (PGD) occurs in 10-25% of cases and remains responsible for significant morbidity and mortality after lung transplantation. Our goal was to explore donor and recipient variables and procedure factors that could be related to early graft failure in cystic fibrosis patients receiving bilateral lung transplantation, the PGD grade being derived from the PaO(2)/FiO(2) ratio measured at the sixth post-operative hour.

Methods: Data from 122 cystic fibrosis patients having undergone lung transplantation in six transplant centres in France were retrospectively analysed.

Incidence and significance of cardiac troponin I release in severe trauma patients.

Background: The incidence and significance of troponin I release and its mechanism are unknown in severe trauma patients. The characteristics of this release were prospectively studied in such patients and correlated with presence of shock, existence of myocardial contusion, and outcome.

Methods: During a 24-month period, serial electrocardiogram recordings and troponin I measurements were performed in all trauma patients admitted at a surgical intensive care unit.

Effect of isoproterenol on the cardiac troponin I degradation and release during early TNFalpha-induced ventricular dysfunction in isolated rabbit heart.

We studied the consequences of an early phase of TNFalpha-induced LV dysfunction and of its treatment by isoproterenol on an isolated rabbit heart preparation. Two dosages of TNFalpha (2 and 4 microg) were infused, followed by isoproterenol (ISO), infused by increasing concentrations from 10 to 10 M. Left ventricular developed pressure (DP) was recorded.

Endotracheal tube cuff pressure is unpredictable in children.

Unlabelled: The use of cuffed tracheal tubes in children younger than 8 yr of age has recently increased, although cuff hyperinflation may cause tracheal mucosal damage. In this study, we sought to measure the cuff pressure (P(cuff)) after initial free air inflation (iP(cuff)) and to follow its evolution throughout the duration of 50% nitrous oxide (N(2)O) anesthesia. One-hundred-seventy-four children, aged 0 to 9 yr, fulfilling the following criteria, were studied: 1).
