    Perioperative Venoarterial Extracorporeal Membrane Oxygenation Support During Heart Transplant
    (2017) Gedik, Ender; Atar, Funda; Ozdemirkan, Aycan; Firat, Aynur Camkiran; Zeyneloglu, Pinar; Sezgin, Atilla; Pirat, Arash; 0000-0002-7175-207X; 0000-0003-2312-9942; 0000-0003-1470-7501; 28260473; AAH-7003-2019; ABI-2971-2020; C-3736-2018
    Objectives: Heart transplant is the only definitive treatment of end-stage heart failure. Venoarterial extracorporeal membrane oxygenation may be used as a bridge to heart transplant. This technique may be used after heart transplant for conditions refractory to medical treatment like primary graft failure. Previously, we reported our experience with patients who received extracorporeal support as a bridge to emergency heart transplant. In this study, we present our perioperative experience with heart transplants in which extracorporeal support was used. Materials and Methods: We retrospectively screened the data of 31 patients who were seen at our center between January 2014 and June 2016. We screened for patients who were admitted to the intensive care unit before transplant and who required venoarterial extracorporeal membrane oxygenation for circulatory support and postoperative patients who required extracorporeal support. Patient demographics and characteristics, clinical data, and extracorporeal support data were collected from our electronic database and patient medical records. Results: There were 14 patients who required peri operative extracorporeal support. Preoperative sup port was performed in 3 patients before transplant, and postoperative support was performed in 11 patients after transplant. The mean age was 37.7 years in patients within the preoperative group and 29.7 years in patients within the postoperative group. One patient with preoperative support and 5 with postoperative support were pediatric patients. The main indication for transplant was dilated cardiomyopathy in both groups (100% and 63.7%). Overall mortality rates were 33% in the preoperative group and 63.7% in the postoperative group. Conclusions: For patients on heart transplant wait lists who are worsening despite optimal medical therapy, venoarterial extracorporeal membrane oxygenation support is a safe and viable last resort. In addition, extracorporeal support can be used during the posttransplant period as salvage therapy in heart recipients with hemodynamic deterioration. In our experience, preoperative extracorporeal support had lower mortality rates compared with postoperative support.

    Postoperative Pleural Effusions After Orthotopic Heart Transplant: Cause, Clinical Manifestations, and Course
    (2016) Ulubay, Gaye; Kupeli, Elif; Dedekarginoglu, Balam Er; Bozbas, Serife Savas; Alekberov, Mahal; Sever, Ozlem Salman; Sezgin, Atilla; 0000-0003-2478-9985; 0000-0002-5826-1997; 0000-0002-7230-202X; 27805531; AAB-5064-2021; AAB-5345-2021; AAI-8064-2021
    Objectives: Postoperative pleural effusions are common in patients who undergo cardiac surgery and orthotopic heart transplant. Postoperative pleural effusions may also occur as postcardiac injury syndrome. Most of these effusions are nonspecific and develop as a harmless complication of the surgical procedure itself and generally have a benign course. Here, we investigated the cause and clinical and laboratory features of postoperative early and late pleural effusions in orthotopic heart transplant patients. Materials and Methods: We retrospectively reviewed the medical records of 50 patients who underwent orthotopic heart transplant between 2004 and 2015 at Baskent University. Patient demographics and clinical and laboratory data, including cause of heart failure, presence of pleural effusions at chest radiography in the first year after transplant, timing of onset, microbiologic and biochemical analyses of pleural effusions, and treatment strategies were noted. Results: Mean age of patients was 39.22 +/- 13.83 years (39 men, 11 women). Reason for heart failure was dilated cardiomyopathy in most patients (76%). Nineteen patients (38%) had postoperative pleural effusions, with 15 patients (78.9%) with pleural effusion during the first week after transplant. Of these, 4 patients had recurrent pleural effusion. A diagnostic thoracentesis was performed in 10 patients, with 4 showing transudative effusion and 6 showing exudative effusion secondary to infection (2 patients), postcardiac injury syndrome (1 patient), and hemo thorax (3 patients). Aspergillus fumigatus was detected by quantitative culture from pleural effusion in 1 patient. Tube thoracoscopy drainage was performed in 10 patients (25%), and 2 patients received antibiotic therapy. Conclusions: Pleural effusions are frequent after cardiac transplant. Complications may occur in a small portion of patients, with most effusions being nonspecific and having a benign course with spontaneous resolution. Early diagnostic thoracentesis could improve post operative outcomes in these patients.
