There are reports of successful lung transplants using SARS-CoV-2+ donors, but the data on their overall outcome is limited. We used the United Network for Organ Sharing Database (UNOS) to identify all lung transplant patients who received lungs from SARS-CoV-2+ donors between 2020 and 2023. There was no difference in survival between those who received lungs from SARS-CoV-2- and SARS-CoV-2+ donors (P = .

Article Synopsis
  • The study investigates the survival outcomes of multiorgan transplants involving heart donations from both donation after circulatory death (DCD) and donation after brain death (DBD) donors.
  • A total of 1,844 DBD and 91 DCD heart transplant patients were analyzed, focusing on combinations with other organs like kidneys, livers, and lungs.
  • Results showed no significant difference in overall survival rates between DCD and DBD groups, despite longer ischemia times in DCD cases, indicating that DCD organ transplants can be as effective as DBD transplants.

Article Synopsis
  • Temporary left ventricular support with Impella 5.5 helps reduce shunting and improve tissue healing in patients with ventricular septal defects after a heart attack.
  • If the heart doesn't recover enough, a permanent HeartMate 3 device can be safely implanted during the repair process.
  • Performing a right ventriculotomy offers several benefits during the surgical repair of ventricular septal defects and the placement of the HeartMate 3.

Objective: Open decannulation from femoral venoarterial extracorporeal membrane oxygenation (VA-ECMO) carries high risk of morbidity, including groin wound infection. This study evaluated the impact of percutaneous decannulation on rates of groin wound infection in patients decannulated from femoral VA-ECMO.

Methods: Between January 1, 2022, and April 30, 2023, 47 consecutive patients received percutaneous femoral VA-ECMO and survived to decannulation.

Objective: The Impella 5.5 (Abiomed, Inc), a surgically implanted endovascular microaxial left ventricular assist device, is increasingly used worldwide and there have been more than 10,000 implants. The purpose of this study is to describe a large-volume, single-center experience with the use of the Impella 5.

Objective: Even though severe tricuspid regurgitation is not uncommon after cardiac transplantation, primary severe tricuspid regurgitation is rare. We present such a case with additional complexities.

Methods: The patient was 44-year-old man with a HeartWare durable left ventricular assist device (Heartware Inc) who received a temporary right ventricular assist device (RVAD) with a ProtekDuo cannula (LivaNova Inc USA) for refractory ventricular fibrillation and underwent a heart transplant as United Network for Organ Sharing Status 1, in the presence of partially compensated cardiogenic shock, renal failure.

Objectives: Approximately 10% of lung transplant recipients have had previous cardiothoracic surgery. We sought to determine if previous surgery affects outcomes after lung transplant at a national level.

Methods: The United Network for Organ Sharing database was analysed from 2005 to 2019 to include adult patients who underwent lung transplant who had previous cardiac surgery and previous thoracic surgery.

A 77 year old man previously implanted with a HeartMate II left ventricular assist device (LVAD) as destination therapy and an implantable cardioverter defibrillator presented with a left upper lobe squamous cell lung cancer. Oncology determined that proton beam therapy was indicated for treatment, and a multidisciplinary team of radiation physicists, radiation oncologists, and LVAD providers developed a protocol to proceed safely. He was successfully treated with combined proton beam radiation therapy and reduced dose chemotherapy.

A 72-year-old man presented with symptomatic, severe aortic valve stenosis and a chronic descending thoracic aorta dissection with descending thoracic aortic aneurysm. After careful consideration, a transcatheter aortic valve was inserted through a transfemoral approach. This case demonstrates feasibility, and consideration should be given to this approach in patients requiring intervention for aortic stenosis.

Objectives: In patients with reduced kidney function there are no established guidelines to suggest combined heart-kidney transplant (HKTx) versus sequential kidney transplant (SKTx) using preoperative value of estimated glomerular filtration (eGFR).

Methods: The United Network for Organ Sharing database was queried from 2000 to 2015 to evaluate survival of HKTx and SKTx population stratified by preoperative eGFR rate <45 mL/min. Aim of the study was to assess the eGFR rate that is most beneficial to perform a concomitant or a SKTx at time of transplant evaluation.

Background: In an effort to expand the donor pool for lung transplants, numerous studies have examined the use of advanced age donors with mixed results, including decreased survival among younger recipients. We evaluated the impact of the use of advanced age donors and single versus double lung transplantation on posttransplant survival.

Methods: The United Network for Organ Sharing database was retrospectively queried between January 2005 and June 2014 to identify lung transplant patients aged at least 18 years.

The effects of pulmonary hypertension (PAH) on survival after heart transplantation are debated, especially for patients with left ventricular assist devices (LVAD). The United Network of Organ Sharing database was retrospectively queried from January 2005 to June 2015 to identify adult patients who underwent heart transplantation. Four groups were defined: patients without PAH, persistent PAH, resolved PAH, and developed PAH between listing and transplant.

Counterpulsation devices (CPDs) require an accurate, reliable electrocardiogram (ECG) waveform for triggering inflation and deflation. Surface electrodes are for short-term use, and transvenous/epicardial leads require invasive implant procedure. A subcutaneous ECG lead configuration was developed as an alternative approach for long-term use with timing mechanical circulatory support (MCS) devices.

Background: Optimum use of donor organs can increase the reach of the transplantation therapy to more patients on waiting list. The heart transplantation (HTx) has remained stagnant in United States over the past decade at approximately 2,500 HTx annually. With the use of the United Network of Organ Sharing (UNOS) deceased donor database (DCD) we aimed to evaluate donor factors predicting donor heart utilization.

Background: Heart transplantation remains the gold standard therapy for end-stage heart failure patients; however, volumes are limited because of donor organ shortage. With the increasing availability of more durable continuous flow left ventricular assist devices (CFLVADs), the matrix of the heart transplantation waiting list and that of donor allocation have seen substantial changes. We aimed to evaluate the impact of the stated reasons for status 1A at time of transplantation on post-transplantation survival in CFVAD patients.
