Abstract

This article presents a case report of a patient who had both COVID-19 and systemic capillary leak syndrome (SCLS), resulting in severe myocardial injury. The patient experienced symptoms such as fever, fatigue, and respiratory distress, and was diagnosed with cardiogenic shock and SCLS. The patient received treatment including mechanical circulatory support, steroids, and intravenous immunoglobulin, which led to an improvement in cardiac function. The article emphasizes the challenges faced in treating patients with COVID-19-related myocardial injury and SCLS, and highlights the potential treatment options available.

Abstract

Limited data exist on the prevalence and prognosis of isolated posterior ST-segment elevation acute myocardial infarction (STEMI), revealed with a posterior chest lead. Furthermore, the utility of a synthesized-V7–9 lead in the diagnosis of STEMI is unclear; therefore, we aimed to evaluate its usefulness. We enrolled 142 consecutive patients with STEMI with the culprit lesion on the left circumflex artery (STEMI-LCx) undergoing percutaneous coronary intervention (PCI) between January 2009 and December 2019. We retrospectively checked the ST-segment change of both standard 12-lead and synthesized-V7–9 lead in all patients with STEMI-LCx. Based on electrocardiogram (ECG) findings, isolated posterior STEMI that was only revealed in synthesized-V7–9 lead was classified as "STEMI-LCx-synV7–9" and the remaining as "STEMI-LCx-12ECG." The prevalence of STEMI-LCx-synV7–9 in patients with STEMI-LCx was assessed. The incidence of all-cause death, cardiac death, and mechanical complications within 30 days, 3 months, and 1 year was also assessed according to each STEMI-LCx. STEMI-LCx-synV7–9 and STEMI-LCx-12ECG occurred in 10 (7.0%) and 132 (93.0%) patients, respectively. No significant difference was found in patients' characteristics between the two groups. The patients with STEMI-LCx-synV7–9 had significantly higher incidences of cardiac death within 3 months and 1 year (30.0% vs. 6.1%, P = 0.031, 30.0% vs. 7.6%, P = 0.050, respectively) and mechanical complications in each follow-up period (20.0% vs. 1.5%, P = 0.025) than those with STEMI-LCx-12ECG. STEMI-LCx-synV7–9 was observed in 7.0% of the patients with STEMI-LCx. Our findings suggest that the synthesized-V7–9 lead helps diagnose isolated posterior STEMI and might improve prognosis in patients with STEMI-LCx. [ABSTRACT FROM AUTHOR]

24. Successful recovery from refractory hypoxia due to right-to-left shunting associated with iatrogenic atrial septal defect after catheter ablation in a patient with a left-ventricular assist device: a case report.

Abstract

Background: Catheter ablation (CA) has been reported to be an effective therapeutic option for ventricular arrhythmias, even in patients with a left-ventricular assist device (LVAD). However, the issues of right-to-left shunting due to iatrogenic atrial septal defect (iASD) associated with procedures for CA have not been well documented. We describe a rare case of refractory hypoxia associated with right-to-left shunting via iASD after CA through the transseptal approach in an LVAD patient., Case Summary: A 52-year-old Asian man with a continuous-flow implantable LVAD and progressive right ventricular (RV) dysfunction was admitted because of refractory ventricular tachycardia (VT) and subsequent right heart failure. Since VT could not be controlled by intravenous administration of multiple antiarrhythmic drugs, VT ablation via the transseptal approach was performed. Ventricular tachycardia was terminated to the sinus rhythm after VT ablation; however, hypoxia associated with significant right-to-left shunting across the iASD was detected. Intensive medical management, such as an adjusted mechanical ventilator to increase pulmonary vascular compliance and adjustment of LVAD pump speed, as well as the use of intravenous inotropes to support impaired RV function successfully stabilized the haemodynamic and improved hypoxia for the disappearance of right-to-left shunting. Echocardiography at 7 months after CA showed that the significant iASD and right-to-left shunting had disappeared., Discussion: The evaluation of RV function prior to VT ablation via the transseptal approach is important in the postoperative management of patients with LVAD, because RV dysfunction may cause refractory hypoxia due to iASD., (© The Author(s) 2022.
