Resolution of Acute Respiratory Distress Syndrome-Induced Takotsubo Cardiomyopathy with Venovenous Extracorporeal Membrane Oxygenation.

Introduction: Takotsubo cardiomyopathy (TTCM) can occur in acute respiratory distress syndrome (ARDS) and a few cases in literature were reported to be associated with hemodynamic instability. All these patients were managed with venoarterial extracorporeal membrane oxygenation (VA-ECMO).Case presentation: We present two patients with ARDS-induced TTCM who were managed successfully with venovenous ECMO (VV-ECMO).

Multidisciplinary Management Strategies for Long COVID: A Narrative Review.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused millions of infections to date and has led to a worldwide pandemic. Most patients had a complete recovery from the acute infection, however, a large number of the affected individuals experienced symptoms that persisted more than 3 months after diagnosis. These symptoms most commonly include fatigue, memory difficulties, brain fog, dyspnea, cough, and other less common ones such as headache, chest pain, paresthesias, mood changes, muscle pain, and weakness, skin rashes, and cardiac, endocrine, renal and hepatic manifestations.

Quadricuspid Aortic Valve: Imaging, Diagnosis, and Prognosis.

Quadricuspid aortic valve is a rare congenital cardiac anomaly with an incidence of 0.008% to 0.043%.

Outcome of lung transplantation in patients with pulmonary alveolar microlithiasis in the era of COVID-19 infection.

Lung transplant recipients are at higher risk of developing COVID-19 infection compared to other solid organ transplants. The risk further increases in the unvaccinated patients. We present a case of a 43-year-old male who underwent bilateral sequential lung transplantation for pulmonary alveolar microlithiasis (PAM) and had an uneventful recovery.

Impact of controlled hypothermic preservation on outcomes following heart transplantation.

Background: Severe primary graft dysfunction (PGD) is a major cause of early mortality after heart transplant, but the impact of donor organ preservation conditions on severity of PGD and survival has not been well characterized.

Methods: Data from US adult heart-transplant recipients in the Global Utilization and Registry Database for Improved Heart Preservation-Heart Registry (NCT04141605) were analyzed to quantify PGD severity, mortality, and associated risk factors. The independent contributions of organ preservation method (traditional ice storage vs controlled hypothermic preservation) and ischemic time were analyzed using propensity matching and logistic regression.

Initial experience and outcomes with a hybrid extracorporeal membrane oxygenation and cardiopulmonary bypass circuit for lung transplantation.

Background: The utilization of extracorporeal life support (ECLS) for intraoperative support during lung transplantation has increased over the past decade. Although veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has recently emerged as the preferred modality over cardiopulmonary bypass (CPB), many centers continue to use both forms of ECLS during lung transplantation. Our novel hybrid VA-ECMO/CPB circuit allows for seamless transition from VA-ECMO to CPB at a significant cost savings compared to a standalone VA-ECMO circuit.

Percutaneous Transseptal Extracorporeal Membrane Oxygenation to Rescue a Failing Right Ventricle in an Animal Model.

Objective: We tested the feasibility and effectiveness of a percutaneous atrial transseptal extracorporeal membrane oxygenation (ECMO) cannulation strategy in a right ventricular failure (RVF) model.

Methods: We performed 4 nonsurvival porcine experiments. Percutaneous transseptal access was achieved using a steerable introducer.

Trends and predictors of intracranial hemorrhage in patients with advanced heart failure on left ventricular assist device from 2005 to 2014 in the United States.

Objectives: Left ventricular assist devices are known to extend survival in patients with advanced heart failure; however, their association with intracranial hemorrhage is also well-known. We aimed to explore the risk trend and predictors of intracranial hemorrhage in patients with left ventricular assist devices.

Material And Methods: We included patients aged 18 years or older with left ventricular assist devices hospitalized in the US from 2005 to 2014 using the National Inpatient Sample.

A Paradigm Shift in Heart Preservation: Improved Post-transplant Outcomes in Recipients of Donor Hearts Preserved With the SherpaPak System.

Traditional ice storage has been the historic standard for preserving donor's hearts. However, this approach provides variability in cooling, increasing risks of freezing injury. To date, no preservation technology has been reported to improve survival after transplantation.

Iatrogenic Acute Ascending Aortic Dissection During Combined Heart/Liver Transplant for Amyloidosis.

We report a case of iatrogenic acute type A aortic dissection (ATAAD) during a combined heart-liver transplant in a patient with amyloid-associated cardiac and hepatic failure. The patient developed ATAAD of the recipient's aorta during the heart transplantation. Because there was no sign of malperfusion or proximal extension into the donor aorta, we proceeded with the liver transplantation and continued medical management for ATAAD.

Novel treatment of bronchopleural fistula in a lung transplant recipient with endobronchial sealant and endobronchial valve placement via robotic-assisted bronchoscopy.

Bronchopleural fistulas (BPFs) are a dreaded complication following pulmonary surgery. Endobronchial valves (EVs), with endobronchial sealant (ES), instilled with robotic bronchoscopy (RB), allow occlusion of BPF, avoiding surgery. The patient was a 71-year-old woman with a history of chronic obstructive pulmonary disease and bronchiectasis who underwent bilateral lung transplantation and wedge resection of the right middle lobe and left lingula.

Transplantation Outcomes with Donor Hearts after Circulatory Death.

Background: Data showing the efficacy and safety of the transplantation of hearts obtained from donors after circulatory death as compared with hearts obtained from donors after brain death are limited.

Methods: We conducted a randomized, noninferiority trial in which adult candidates for heart transplantation were assigned in a 3:1 ratio to receive a heart after the circulatory death of the donor or a heart from a donor after brain death if that heart was available first (circulatory-death group) or to receive only a heart that had been preserved with the use of traditional cold storage after the brain death of the donor (brain-death group). The primary end point was the risk-adjusted survival at 6 months in the as-treated circulatory-death group as compared with the brain-death group.

Short-term outcomes of heart transplant patients bridged with Impella 5.5 ventricular assist device.

Aims: We sought to investigate the outcomes of heart transplant patients supported with Impella 5.5 temporary mechanical circulatory support.

Methods And Results: Patient demographics, perioperative data, hospital timeline, and haemodynamic parameters were followed during initial admission, Impella support, and post-transplant period.

No Sex Differences in the Prevalence of Intracranial Aneurysms in Patients with Ascending Thoracic Aortic Aneurysms: A Multi-Center Experience.

Background: Previous studies suggest a coprevalence of intracranial aneurysms (IA) in patients with infrarenal abdominal aortic aneurysms (AAA). We reviewed our multicenter experience in the detection/treatment of IAs in patients with ascending thoracic aortic aneurysms (ATAA) relative to patients without ATAA.

Methods: Surgical cases of ATAA repaired at 3 sites from January 1998 to December 2018 were retrospectively reviewed.

Coronavirus Disease 2019 Causing Infection of Transplanted Lung Allograft: A Pitfall of Prolonged Shedding of Severe Acute Respiratory Syndrome Coronavirus-2 Pretransplant.

Coronavirus disease 2019 (COVID-19) pandemic has led to considerable morbidity and mortality across the world. Lung transplant is a viable option for a few with COVID-19-related lung disease. Whom and when to transplant has been the major question impacting the transplant community given the novelty of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Transesophageal echocardiography: a tool for intraoperative assessment of coronary blood flow.

Transesophageal echocardiography (TEE) has become an indispensable part of cardiac surgery, but its potential for assessing coronary anatomy and blood flow remains underutilised. This case report presents a case of acute iatrogenic left main coronary artery obstruction following re-operative aortic valve replacement that was promptly diagnosed by intraoperative TEE and managed successfully by Bentall operation. We also emphasise the technique of TEE for coronary evaluation, its caveats and its clinical application during cardiac surgery.

Survival Outcomes of Lung Transplant Recipients From Donors With Abnormal Kidney Function.

Background: Recovering lungs with pulmonary edema due to abnormal kidney function is considered one of the expanded selection criteria for lung transplant. The aim of this study is to assess lung transplant recipients' survival from donors with abnormal kidney function and to determine differences in lung recovery rates from donors with and donors without abnormal kidney function.

Methods: We reviewed the United Network for Organ Sharing registry for first-time adult lung transplant donors and recipients from June 2005 to March 2017.

Multicenter Registry Using Propensity Score Analysis to Compare a Novel Transport/Preservation System to Traditional Means on Postoperative Hospital Outcomes and Costs for Heart Transplant Patients.

The standard method for cardiac allograft preservation for the past 50 years has been static storage using crushed ice. A heart transplant transportation system designed to improve preservation quality with temperature monitoring, the Paragonix SherpaPak Cardiac Transport System (SCTS), was evaluated for its impact on postoperative costs relative to conventional ice storage. Observational US multicenter registry data collected during the August 2015 to November 2021 timeframe from 12 transplant hospitals were analyzed using logistic regression analysis and propensity matching to balance measured baseline covariates and to reduce selection bias.
