RESUMO
OBJECTIVES: The aim of this analysis was to compare the effect of extubating in the operating room (OR) versus and the intensive care unit (ICU) among patients undergoing coronary artery bypass grafting (CABG). DESIGN: A retrospective cohort analysis. SETTING: Ten cardiac referral hospitals in Latin America; participants of the São Paulo Registry of Cardiovascular Surgery II (REPLICCAR II). PARTICIPANTS: The database included a total of 4,015 patients who underwent primary and isolated CABG surgery and were ≥18 years old, of whom 205 patients were extubated in the OR. INTERVENTIONS: The analysis was made after a propensity score matching (PSM) adjustment in the population sample of patients extubated in the OR and ICU by the following variables: sex, age, body mass index, smoking, type of surgery, chronic obstructive pulmonary disease, preoperative atrial fibrillation, cardiopulmonary bypass time, preoperative creatinine, and preoperative left ventricular ejection fraction. MEASUREMENTS AND MAIN RESULTS: This study focused on the analysis of the ICU and hospital length of stay, need for reintubation, morbidity, and mortality. After PSM, 402 patients were analyzed. Both groups had similar baseline characteristics, such as age (p = 0.132), sex (p = 1.00), and estimated risk of prolonged ventilation (>24 hours, p = 0.168); however, the median ventilation time was significantly shorter in the group extubated in the OR compared to the ICU group (5.67 hours v 17.55 hours, p < 0.001). The group of patients extubated in the ICU had a longer postoperative stay (7.54 ± 3.40 days v 6.41 ± 2.91 days, p < 0.001) and longer total hospitalization time (11.49 ± 5.70 days v 10.36 ± 5.72, p = 0.013) compared to those extubated in the OR. The authors did not observe a significant difference in the need for reintubation, morbidity, or mortality rates among the evaluated groups. CONCLUSIONS: In the REPLICCAR II database, extubation performed in the OR was associated with a reduced length of postoperative and total hospital stays compared to extubation in the ICU.

OBJECTIVE: The objective of this study is to evaluate protamine sulfate effects on graft's blood flow by comparing transit-time flow measurement (TTFM) values before and after protamine administration. METHODS: This is an observational study with data collected between years 2018 and 2020. Immediate graft patency was evaluated using TTFM. Only patients with TTFM parameters registered before and after protamine infusion were included. The main three parameters studied were: mean graft flow (MGF), pulsatility index (PI), and diastolic flow (DF). In the first analysis, all conduits were evaluated regardless of the surgical technique used. In a second analysis, on-pump and off-pump groups were compared. Evaluated grafts were left internal thoracic artery, saphenous vein graft (SVG), radial artery, and right internal thoracic artery. Since SVG was numerically the most used graft, an exclusive analysis was created. RESULTS: Our study included 575 patients, resulting in a total of 1686 grafts, mean 2.93 grafts/patient. Off-pump surgery was performed in 158 patients. Before protamine infusion, inadequate TTFM parameters were observed in 3.8% of grafts. Overall, after protamine administration, MGF decreased in all grafts, but its reduction was not statistically significant. PI values increased in the SVG and DF values reduced in LIMA grafts. SVG group analysis showed that after protamine PI values were higher in OM1 and RCA. DF values increased in RCA. The comparison between off and on-pump surgeries, showed that in off-pump cases TTFM measures did not present statistically significant differences. CONCLUSION: Significant variations were observed in TTFM values before and after protamine administration. Although different, those values remained within the normal reference ranges. We recommend that flow measurement should be performed before protamine infusion.

OBJECTIVE: The aim of this study was to evaluate outcome measures between our standard multidose cardioplegia protocol and a del Nido cardioplegia protocol in congenital heart surgery patients. METHODS: Retrospective single-center study including 250 consecutive patients that received del Nido cardioplegia (DN group) with a mandatory reperfusion period of 30% of cross clamp time and 250 patients that received a modified St. Thomas' solution (ST group). Groups were matched by age, weight, gender, and Risk Adjustment for Congenital Heart Surgery (RACHS-1) scores. Preoperative hematocrit and oxygen saturation were also recorded. Outcomes analyzed were the vasoactive inotropic score (VIS), lactate, ventilation time, ventricular dysfunction with low cardiac output syndrome (LCOS), intensive care unit (ICU) length of stay (LOS), hospital LOS, bypass and aortic cross-clamp times, and in-hospital mortality. RESULTS: Both groups were comparable demographically. Statistically significant differences (p ⩽ 0.05) were noted for cardiac dysfunction with LCOS, hematocrit at end of surgery (p = 0.0038), VIS on ICU admission and at end of surgery (p = 0.0111), and ICU LOS (p = 0.00118) with patients in the DN group having more desirable values for those parameters. Other outcome measures did not reach statistical significance. CONCLUSION: In our congenital cardiac surgery population, del Nido cardioplegia strategy was associated with less ventricular dysfunction with LCOS, a lower VIS and decreased ICU LOS compared with patients that received our standard myocardial protection using a modified St. Thomas' solution. Despite the limitation of this study, including its retrospective nature and cohort size, these data supported our transition to incorporate del Nido cardioplegia solution with a mandatory reperfusion period as the preferred myocardial protection method in our program.

OBJECTIVES: This article aimed to compare the outcomes after hybrid revascularization with conventional coronary artery bypass grafting (CABG) surgery. BACKGROUND: The concept of hybrid coronary revascularization combines the advantages of CABG and percutaneous coronary intervention to improve the treatment of patients with complex multivessel disease. METHODS: The Myocardial hybrid revascularization versus coronary artERy bypass GraftING for complex triple-vessel disease-MERGING study is a pilot randomized trial that allocated 60 patients with complex triple-vessel disease to treatment with hybrid revascularization or conventional CABG (2:1 ratio). The primary outcome was the composite of all-cause death, myocardial infarction, stroke, or unplanned repeat revascularization at 2 years. RESULTS: Clinical and anatomical characteristics were similar between groups. After a mean follow-up of 802 ± 500 days, the primary endpoint rate was 19.3% in the hybrid arm and 5.9% in the CABG arm (p = NS). The incidence of unplanned revascularization increased over time in both groups, reaching 14.5 versus 5.9% in the hybrid and in the CABG groups, respectively (p = .4). Of note, in the hybrid group, there were no reinterventions driven by the occurrence of stent restenosis. CONCLUSIONS: Hybrid myocardial was feasible but associated with increasing rates of major adverse cardiovascular events during 2 years of clinical follow-up, while the control group treated with conventional surgery presented with low rates of complications during the same period. In conclusion, before more definitive data arise, hybrid revascularization should be applied with careful attention in practice, following a selective case-by-case indication.

Arterial revascularization, and in particular, left internal mammary artery (LIMA), has shown to improve survival of patients with coronary artery disease. Complete revascularization often requires the use of other grafts and saphenous vein graft is still the most common conduit used. Several other types of grafts have been utilized during revascularization, including the radial artery and gastroepiploic artery. It is recognized that its venous structure can change when submitted to long-term blood pressure regimen. We, herein, report left internal mammary vein (LIMV) utilized as a novel conduit for coronary artery revascularization, that was patent after 6 years. LIMV is an easy graft to harvest if the LIMA is dissected as a pedicle. The long-term patency of LIMV is unknown, but its usage could be suggested for elderly patients with peripheral vascular disease, when long graft patency is not required.

OBJECTIVES: The goal of this study was to describe and evaluate our simulation training program on biological models for the cardiovascular surgery residency program at our institution. MATERIAL AND METHODS: Since 2016, with the purpose to develop better practical performance and evaluate the improvement of resident's surgical skills, a simulation training program was implemented, composed of some elemental procedures in cardiovascular surgery. It was established with one wet lab session weekly lasting 2 h, coached by two expert cardiovascular surgeons. Bovine and porcine hearts were used as biological models. At the end of the hands-on program, an objective assessment consisting of two practical modules was applied and performance was rated by way of a 5-point scale. In addition, to provide a subjective assessment, each resident filled out a questionnaire consisting of three items reviewing the overall quality of the workshops on a 10-point scale. RESULTS: The objective evaluation applied at the end of the training program consisted of valve replacement and coronary artery bypass grafting (CABG) modules. The mean performance rating scores for the valve replacement module ranged from 4.2 to 4.79, and CABG, from 4.33 to 4.87. Regarding subjective assessment, all items evaluated, such as expert's didactics, simulation performance, and biological simulator fidelity, received high grades (above 9 on a 10-point scale). CONCLUSIONS: Simulator training on biological models for cardiac surgery medical residents is a simple and effective learning method of surgical skills.

INTRODUCTION: Ventricular septal rupture (VSR) is a serious mechanical complication after acute coronary syndrome and is related to high mortality. Even with advances in the management of acute myocardial infarction (AMI) such as reperfusion therapies, complication rates are still high. During quarantine, patients presenting mechanical complications after AMI have increased in our institution. METHODS: From a retrospective database analysis in our institution between the years 2004 and 2020, we identified 37 cases of VSR after AMI. Four chronic cases were excluded from our analysis. The primary endpoint was to identify baseline characteristics that increased 30-day mortality. RESULTS: Among 33 acute cases of VSR, 24 cases were submitted to surgery. The 30-day mortality of the operated patients was 45.8%. From 2004 to 2019 our average number of operations of VSR was 1.9 cases/year with an increase to 4 cases/year in 2020. Diabetes mellitus, age, cardiogenic shock, and use of intra-aortic balloon pump were associated with significantly increased mortality using logistic regression. CONCLUSION: We reported an increased number of mechanical complication cases from April to September 2020, compared to our historical records. Despite therapeutic advances, mortality rates remain high. Although the number of cases is small to conclude that the pandemic was responsible for this augmentation, we believe that it is related to the decreased number of patients seeking medical assistance.

BACKGROUND: Anomalous aortic origin of coronary artery is a rare finding, with varied presentation and symptomatology. Increasingly recognized by cardiac imaging, when found it raises questions about the appropriate approach and management. CASE PRESENTATION: We present a case of an 11-year-old female who presented with episodes of shortness of breath, angina, and syncope during exercise. Further investigation demonstrated episodes of nonsustained ventricular tachycardia on Holter and coronary angiotomography revealed that the left coronary artery had an anomalous origin from the right cusp with initial short intramural segment and significant external compression in its initial course between the aorta and the pulmonary artery. The patient was submitted to surgical correction with dissection of left coronary artery posterior to the pulmonary artery, coronary arteriotomy, roof ampliation with the autologous pericardium, and creation of neo-ostium in aorta. The patient had a satisfactory postoperative recovery, was discharged on the fifth-day post-op, and remains asymptomatic after 14 months of follow-up. Herein we present surgical video and postoperative echo and computed tomography scan.

BACKGROUND AND AIM OF THE STUDY: This study analyzed the arrival of coronavirus disease 2019 (COVID-19) in Brazil and its impact on coronary artery bypass grafting (CABG) surgery. METHODS: Patients undergoing isolated CABG in six hospitals in Brazil were divided into two periods: pre-COVID-19 (March-May 2019, N = 468) and COVID-19 era (March-May 2020, N = 182). Perioperative data were included on a dedicated REDCap platform. Patients with clinical and tomographic criteria and/or PCR (+) for severe acute respiratory syndrome coronavirus 2 infection were considered COVID-19 (+). Logistic regression analysis was performed to create a multiple predictive model for mortality after CABG in COVID-19 era. RESULTS: Compared to 2019, in 2020, CABG surgeries had a 2.8-fold increased mortality risk (95% confidence interval [CI]: 1-7.6, p = .041), patients who evolved with COVID-19 had a 11-fold increased mortality risk (95% CI: 2.2-54.9, p < .003), rates of morbidities and readmission to the intensive care unit. The surgical volume was decreased by 60%. The model to predict mortality after CABG in the COVID-19 era was validated with good calibration (Hosmer-Lemeshow = 1.43) and discrimination (receiver operating characteristic = 0.78). CONCLUSION: The COVID-19 pandemic had an adverse impact on mortality, morbidity and volume of patients undergoing CABG.

INTRODUCTION: The neutrophil-lymphocyte ratio (NLR) has been associated with worse outcomes in patients undergoing coronary artery bypass graft surgery. Little is known about this association in the pediatric population who require surgery for congenital heart defects, especially in patients with a single ventricle (SV). OBJECTIVE: To analyze the association of the preoperative NLR with outcomes in patients undergoing the bidirectional Glenn procedure. METHODS: This study involved a retrospective cohort analysis of 141 consecutive patients with SV undergoing the bidirectional Glenn procedure between January 2011 and December 2017 in two centers. The preoperative NLR was included in the last hemogram test before surgery. According to the NLR level, the patients were divided into group I (NLR < 1), group II (NLR between 1 and 2), and group III (NLR > 2). The primary endpoint was total hospital length of stay (LOS), and secondary endpoints were mechanical ventilation (MV) time, intensive care unit (ICU) LOS, ventricular dysfunction, complications, and middle-term mortality. RESULTS: The average follow-up duration was 48 months. There were 61, 47, and 33 patients in groups I, II, and III, respectively. Patients in group III exhibited an increased risk of prolonged total hospital LOS (P = .00). An increase in MV time (P = .03) and ICU LOS (P = .02) was also observed in this group, and these patients experienced greater mortality in 24 months following the surgery (P = .03). There was no association between the NLR and ventricular dysfunction (P = .26) and complications (P = .46). CONCLUSION: A high preoperative NLR was associated with worse outcomes in patients with SV physiology undergoing the bidirectional Glenn procedure.

The objective of this study was to compare the hemodynamic performances and gaseous microemboli (GME) handling ability of two pediatric oxygenators in a simulated pediatric cardiopulmonary bypass (CPB) model and the importance of adding an arterial filter in the circuit. The circuit consisted of a Braile Infant oxygenator or a Maquet Quadrox-I Pediatric oxygenator without integrated arterial filter (parallel arrangement), 1/4 in. ID tubing A-V loop, and a 12-Fr arterial cannula, primed with lactated Ringer's solution and packed red blood cells. Trials were conducted at flow rates ranging from 500 to 2000 mL/min (500 mL/min increment) at 35°C and 28°C. Real-time pressure and flow data were recorded using a custom-based data acquisition system. For GME testing, 5 cc of air was manually injected into the venous line. GME were recorded using the Emboli Detection and Classification Quantifier (EDAC) System. An additional experiment using a separate arterial filter was conducted. There was no difference in the mean circuit pressure, pressure drop, total hemodynamic energy level, and energy loss between the two oxygenators. The venous line pressures were higher in the Braile than in the Quadrox group during all trials (P <0.01). GME count and volume at pre-/post oxygenator and pre-cannula sites in the Quadrox were lower than the Braile group at high flow rates (P < 0.05). In the additional experiment, an arterial filter captured a significant number of microemboli at all flow rates. The Braile Infant oxygenator has a matched hemodynamic characteristic with the Quadrox-i Pediatric oxygenator. The Quadrox-i has a better GME handling ability compared with the Braile Infant oxygenator. Regardless of type of oxygenator an additional arterial filter decreases the number of GME.

OBJECTIVES: To evaluate the effects of goal-directed therapy on outcomes in high-risk patients undergoing cardiac surgery. DESIGN: A prospective randomized controlled trial and an updated metaanalysis of randomized trials published from inception up to May 1, 2015. SETTING: Surgical ICU within a tertiary referral university-affiliated teaching hospital. PATIENTS: One hundred twenty-six high-risk patients undergoing coronary artery bypass surgery or valve repair. INTERVENTIONS: Patients were randomized to a cardiac output-guided hemodynamic therapy algorithm (goal-directed therapy group, n = 62) or to usual care (n = 64). In the goal-directed therapy arm, a cardiac index of greater than 3 L/min/m was targeted with IV fluids, inotropes, and RBC transfusion starting from cardiopulmonary bypass and ending 8 hours after arrival to the ICU. MEASUREMENTS AND MAIN RESULTS: The primary outcome was a composite endpoint of 30-day mortality and major postoperative complications. Patients from the goal-directed therapy group received a greater median (interquartile range) volume of IV fluids than the usual care group (1,000 [625-1,500] vs 500 [500-1,000] mL; p < 0.001], with no differences in the administration of either inotropes or RBC transfusions. The primary outcome was reduced in the goal-directed therapy group (27.4% vs 45.3%; p = 0.037). The goal-directed therapy group had a lower occurrence rate of infection (12.9% vs 29.7%; p = 0.002) and low cardiac output syndrome (6.5% vs 26.6%; p = 0.002). We also observed lower ICU cumulative dosage of dobutamine (12 vs 19 mg/kg; p = 0.003) and a shorter ICU (3 [3-4] vs 5 [4-7] d; p < 0.001) and hospital length of stay (9 [8-16] vs 12 [9-22] d; p = 0.049) in the goal-directed therapy compared with the usual care group. There were no differences in 30-day mortality rates (4.8% vs 9.4%, respectively; p = 0.492). The metaanalysis identified six trials and showed that, when compared with standard treatment, goal-directed therapy reduced the overall rate of complications (goal-directed therapy, 47/410 [11%] vs usual care, 92/415 [22%]; odds ratio, 0.40 [95% CI, 0.26-0.63]; p < 0.0001) and decreased the hospital length of stay (mean difference, -5.44 d; 95% CI, -9.28 to -1.60; p = 0.006) with no difference in postoperative mortality: 9 of 410 (2.2%) versus 15 of 415 (3.6%), odds ratio, 0.61 (95% CI, 0.26-1.47), and p = 0.27. CONCLUSIONS: Goal-directed therapy using fluids, inotropes, and blood transfusion reduced 30-day major complications in high-risk patients undergoing cardiac surgery.

INTRODUCTION: Along with cardiopulmonary bypass time, aortic cross-clamping time is directly related to the risk of complications after heart surgery. The influence of the time difference between cardiopulmonary bypass and cross-clamping times (TDC-C) remains poorly understood. OBJECTIVE: To assess the impact of cardiopulmonary bypass time in relation to cross-clamping time on immediate results after coronary artery bypass grafting in the Registro Paulista de Cirurgia Cardiovascular (REPLICCAR) II. METHODS: Analysis of 3,090 patients included in REPLICCAR II database was performed. The Society of Thoracic Surgeons outcomes were evaluated (mortality, kidney failure, deep wound infection, reoperation, cerebrovascular accident, and prolonged ventilation time). A cutoff point was adopted, from which the increase of this difference would affect each outcome. RESULTS: After a cutoff point determination, all patients were divided into Group 1 (cardiopulmonary bypass time < 140 min., TDC-C < 30 min.), Group 2 (cardiopulmonary bypass time < 140 min., TDC-C > 30 min.), Group 3 (cardiopulmonary bypass time > 140 min., TDC-C < 30 min.), and Group 4 (cardiopulmonary bypass time > 140 min., TDC-C > 30 min.). After univariate logistic regression, Group 2 showed significant association with reoperation (odds ratio: 1.64, 95% confidence interval: 1.01-2.66), stroke (odds ratio: 3.85, 95% confidence interval: 1.99-7.63), kidney failure (odds ratio: 1.90, 95% confidence interval: 1.32-2.74), and in-hospital mortality (odds ratio: 2.17, 95% confidence interval: 1.30-3.60). CONCLUSION: TDC-C serves as a predictive factor for complications following coronary artery bypass grafting. We strongly recommend that future studies incorporate this metric to improve the prediction of complications.

BACKGROUND: The impact of quality improvement initiatives program (QIP) on coronary artery bypass grafting surgery (CABG) remains scarce, despite improved outcomes in other surgical areas. This study aims to evaluate the impact of a package of QIP on mortality rates among patients undergoing CABG. MATERIALS AND METHODS: This prospective cohort study utilized data from the multicenter database Registro Paulista de Cirurgia Cardiovascular II (REPLICCAR II), spanning from July 2017 to June 2019. Data from 4018 isolated CABG adult patients were collected and analyzed in three phases: before-implementation, implementation, and after-implementation of the intervention (which comprised QIP training for the hospital team). Propensity Score Matching was used to balance the groups of 2170 patients each for a comparative analysis of the following outcomes: reoperation, deep sternal wound infection/mediastinitis ≤30 days, cerebrovascular accident, acute kidney injury, ventilation time >24 h, length of stay <6 days, length of stay >14 days, morbidity and mortality, and operative mortality. A multiple regression model was constructed to predict mortality outcomes. RESULTS: Following implementation, there was a significant reduction of operative mortality (61.7%, P =0.046), as well as deep sternal wound infection/mediastinitis ( P <0.001), sepsis ( P =0.002), ventilation time in hours ( P <0.001), prolonged ventilation time ( P =0.009), postoperative peak blood glucose ( P <0.001), total length of hospital stay ( P <0.001). Additionally, there was a greater use of arterial grafts, including internal thoracic ( P <0.001) and radial ( P =0.038), along with a higher rate of skeletonized dissection of the internal thoracic artery. CONCLUSIONS: QIP was associated with a 61.7% reduction in operative mortality following CABG. Although not all complications exhibited a decline, the reduction in mortality suggests a possible decrease in failure to rescue during the after-implementation period.

OBJECTIVE: To investigate the association between body mass index (BMI), obesity, clinical outcomes, and mortality following coronary artery bypass grafting (CABG) in Brazil using a large sample with one year of follow-up from the Brazilian Registry of Cardiovascular Surgeries in Adults (or BYPASS) Registry database. METHODS: A multicenter cohort-study enrolled 2,589 patients submitted to isolated CABG and divided them into normal weight (BMI 20.0-24.9 kg/m2), overweight (BMI 25.0-29.9 kg/m2), and obesity (BMI > 30.0 kg/m2) groups. Inpatient postoperative outcomes included the most frequently described complications and events. Collected post-discharge outcomes included rehospitalization and mortality rates within 30 days, six months, and one year of follow-up. RESULTS: Sternal wound infections (SWI) rate was higher in obese compared to normal-weight patients (relative risk [RR]=5.89, 95% confidence interval [CI]=2.37-17.82; P=0.001). Rehospitalization rates in six months after discharge were higher in obesity and overweight groups than in normal weight group (χ=6.03, P=0.049); obese patients presented a 2.2-fold increase in the risk for rehospitalization within six months compared to normal-weight patients (RR=2.16, 95% CI=1.17-4.09; P=0.045). Postoperative complications and mortality rates did not differ among groups during time periods. CONCLUSION: Obesity increased the risk for SWI, leading to higher rehospitalization rates and need for surgical interventions within six months following CABG. Age, female sex, and diabetes were associated with a higher risk of mortality. The obesity paradox remains controversial since BMI may not be sufficient to assess postoperative risk in light of more complex and dynamic evaluations of body composition and physical fitness.

INTRODUCTION: Deep sternal wound infections (DSWI) are so serious and costly that hospital services continue to strive to control and prevent these outcomes. Microcosting is the more accurate approach in economic healthcare evaluation, but there are no studies in this field applying this method to compare DSWI after isolated coronary artery bypass grafting (CABG). This study aims to evaluate the incremental risk-adjusted costs of DSWI on isolated CABG. METHODS: This is a retrospective, single-center observational cohort study with a propensity score matching for infected and non-infected patients to compare incremental risk-adjusted costs between groups. Data to homogeneity sample was obtained from a multicentric database, REPLICCAR II, and additional sources of information about costs were achieved with the electronic hospital system (Si3). Inflation variation and dollar quotation in the study period were corrected using the General Market Price Index. Groups were compared using analysis of variance, and multiple linear regression was performed to evaluate the cost drivers related to the event. RESULTS: As expected, infections were costly; deep infection increased the costs by 152% and mediastinitis by 188%. Groups differed among hospital stay, exams, medications, and multidisciplinary labor, and hospital stay costs were the most critical cost driver. CONCLUSION: In summary, our results demonstrate the incremental costs of a detailed microcosting evaluation of infections on CABG patients in São Paulo, Brazil. Hospital stay was an important cost driver identified, demonstrating the importance of evaluating patients' characteristics and managing risks for a faster, safer, and more effective discharge.

INTRODUCTION: The aims of this study were to determine the incidence of severe and moderate primary graft dysfunction (PGD) in our center, to identify, retrospectively, donors' and recipients' risk factors for PGD development, and to evaluate the impact of PGD within 30 days after heart transplantation. METHODS: Donors' and recipients' medical records of 64 consecutive adult cardiac transplantations performed between January 2016 and June 2017 were reviewed. The International Society for Heart and Lung Transplantation (ISHLT) criteria were used to diagnose moderate and severe PGD. Associations of risk factors for combined moderate/severe PGD were assessed with appropriate statistical analyses. RESULTS: Sixty-four patients underwent heart transplantation in this period. Twelve recipients (18.7%) developed severe or moderate PGD. Development of PGD was associated with previous donor cardiopulmonary resuscitation and a history of prior heart surgery in the recipient (P=0.01 and P=0.02, respectively). The 30-day in hospital mortality was similar in both PGD and non-PGD patients. CONCLUSION: The use of the ISHLT criteria for PGD is important to identify potential risk factor. The development of PGD did not affect short-term survival in our study. More studies should be done to better understand the pathophysiology of PGD.
