RESUMO
Background: In this study, we aimed to evaluate primary outcomes and main characteristics of emergency and elective/urgent cardiovascular surgeries which were performed in the first three months of the novel coronavirus disease 2019 (COVID-19) pandemic in our center. Methods: Between March 11th, 2020 and June 11th, 2020, a total of 209 patients (44 males, 165 females; mean age: 57.3±12.8 years; range, 20 to 80 years) who underwent emergency or elective/urgent surgery with cardiovascular pathologies were retrospectively analyzed. The patients were classified as emergency and elective/urgent according to the level of necessity of the surgical procedure at the time of hospital admission. Pre-, intra-, and postoperative data of the patients were recorded. Results: During the study period, 156 elective/urgent and 74 emergency cardiovascular surgeries were performed. Six COVID-19 (+) patients were operated emergently. The number of acute aortic dissection and peripheral vascular surgery was higher in the emergency group (p<0.05). Two patients who were COVID-19 (-) preoperatively became COVID-19 (+) in the postoperative period. In these patients, acute respiratory distress syndrome developed, and extracorporeal membrane oxygenation support was needed. Four patients who needed post-cardiotomy extracorporeal membrane oxygenation support due to low cardiac output were COVID-19 (-) both in the pre- and postoperative periods. The overall in-hospital mortality rate was 9.1%. Conclusion: Even during pandemic such as COVID-19, referral centers with experienced personnel can provide non-pandemic healthcare with a quality close to the daily routine.
RESUMO
BACKGROUND: Sutureless aortic valve replacement (SU-AVR) and transcatheter aortic valve implantation (TAVI) are becoming increasingly common. The aim of this study is to compare the clinical outcome and cost-effectiveness of the two methods. METHODS: In this study, cross-sectional retrospective data were collected on 327 patients who underwent SU-AVR (n = 168) and TAVI (n = 159). Homogeneous groups were provided by the "propensity score matching" method, and 61 patients from the SU-AVR group and 53 patients from the TAVI group were included in the study sample. RESULTS: The two groups did not have statistically different death rates, complications after surgery, lengths of hospital stays, or visits to the intensive care unit. It is stated that the SU-AVR method provides an additional 1.14 Quality-Adjusted Life Year (QALY) compared to the TAVI method. The TAVI was more expensive than the SU-AVR in our study, but the difference was not statistically significant ($40,520.62 vs. $38,405.62, p > 0.05). For SU-AVR, the most expensive factor was the length of stay in the intensive care unit; for TAVI, it was arrhythmia, bleeding, and renal failure. CONCLUSIONS: These bioprostheses are safe and effective treatments for valve stenosis. Clinical outcomes were similar between the two groups. Therefore, clinicians may find it difficult to determine an effective treatment strategy. According to the evaluation made in terms of cost-effectiveness, it was found that the SU-AVR method gave a higher QALY at a lower cost compared to the TAVI method. However, this result is not statistically significant.

BACKGROUND: Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, causes endothelial dysfunction which is an important risk factor for mortality in adult cardiovascular diseases. We aimed to investigate whether there was a relationship between the aortic cross-clamping (ACC) time and serum ADMA level in aortic coarctation surgery and importance of the serum ADMA level as a marker of mortality and morbidity. METHOD: Twenty-two patients undergoing surgery for aortic coarctation in the neonatal and early infant period were included in the study, and the patients were divided into two groups according to the aortic cross-clamping time (Group I: <20-min, Group II: >20-min). RESULTS: In Group I, preoperative and postoperative mean ADMA values of the patients were 0.57 ± 0.78 and 0.54 ± 0.83 µmol/L, respectively. In Group II, preoperative and postoperative mean ADMA values of the patients were 0.69 ± 0.93 and 1.10 ± 0.30 µmol/L, respectively. Preoperative-postoperative change of ADMA correlates with ACC time (r = .802, p < .005) and duration of postoperative inotropic support (r = .719, p < .05). Also a high correlation has been found between the ACC time and duration of inotropic support in both groups (r = .689, p < .05). CONCLUSION: Perioperative serum ADMA levels could be used as a prognostic bio-marker in the patients undergoing aortic coarctation repair. Treatments to reduce serum ADMA levels can be valuable for preventing mortality and morbidity which develop after surgeries in a transient ischemia setting by clamping the aorta.

PURPOSE: To evaluate the clinical impact of pleurotomy during skeletonized internal thoracic artery (ITA) harvesting in patients undergoing on-pump coronary artery bypass grafting (CABG). METHODS: Consecutive patients (n = 758) who underwent CABG with skeletonized ITA were divided into 2 groups according to pleural integrity: open pleura (OP) and closed pleura (CP). Propensity score matching was performed after retrospective data extraction. The measured outcomes were postoperative pulmonary and hemorrhagic complications, 30-day mortality, and duration of hospital stay. RESULTS: Among 236 propensity score-matched pairs, there was no statistically significant difference between the 2 groups in terms of first 30-day mortality (OP, n = 7 [3%]; CP, n = 5 [2.5%]), blood product use (OP, 0.90 ± 0.71; CP, 0.74 ± 0.7), or median duration of hospital stay. The incidence of postoperative pleural effusion, thoracentesis, prolonged mechanical ventilation, respiratory failure, excessive drainage, cardiac tamponade, and reexploration and the number of patients requiring transfusion were similar in both groups. CONCLUSION: The clinical effect of pleural protection or pleurotomy on postoperative outcomes is limited in patients undergoing on-pump CABG with skeletonized ITA.

Background: Sarcopenia is a syndrome that can be associated with unfavorable outcomes after colorectal cancer surgical procedures. The present study evaluates the relationship between sarcopenia and surgical site infections (SSIs) that can occur after colorectal cancer operations and that are a significant cause of morbidity. Methods: The research was designed as a retrospective study in which data were collected on patients who underwent colorectal cancer surgical procedures between January 2013 and July 2019. A diagnosis of sarcopenia was established based on the skeletal muscle index (SMI), calculated from pre-operative computed tomography scans. The SSI scores of patients with sarcopenia (sarcopenic group, SG) and those without sarcopenia (non-sarcopenic group, NSG) were compared, and a logistic regression analysis was performed to determine the risk factors for SSI. Results: A total of 209 patients with a mean age of 61.2 years were included in the study. Post-operative complications (Clavien-Dindo ≥1) developed in 97 (46.4%) patients, SSIs developed in 46 (22%) patients, and sarcopenia developed in 97 (46.4%) patients. The mean age was 64.8 years in the SG group and 58.1 years in the NSG group (p = 0.016). No significant relationship was found between the development of SSI and sarcopenia (20 (20.6%) patients in the SG vs. 26 (23.2%) patients in the NSG, p = 0.65). Those in whom superficial SSIs developed in the early period formed the largest group (20 patients). The most commonly detected micro-organism was Escherichia coli with a rate of 55%. In a multi-variable logistic regression analysis, only the non-laparoscopic approach was identified as a risk factor (odds ratio 3.83; 95% confidence interval 1.26-11.58; p = 0.017). Conclusions: The present study reports no relationship between sarcopenia and SSI after colorectal cancer operations. The authors consider that studies that endeavor to reduce the incidence of SSI, as a significant cause of morbidity after colorectal surgical procedures, should be supported.

OBJECTIVE: Congenital heart diseases are observed in 5 to 8 of every 1000 live births. The presence of a valuable biomarker during the surgical periods may aid the clinician in a more accurate prognosis during treatment. METHODS: For this reason, surfactant protein B plasma levels may help to evaluate patients with cardiac problems diminishing the alveolocapillary membrane stability. In this study, plasma levels of this biomarker were measured in the preoperative and postoperative periods. This study was conducted to detect the differences between pulmonary hypertensive and normotensive patients. The differences before and after cardiopulmonary bypass were examined. RESULTS: The differences in cardiopulmonary bypass time, cross-clamp time , inotropic support dose, and duration of intensive care of patients with and without pulmonary hypertensive were found to be statistically significant (P<0.05). The results revealed that this pathophysiological state was related to other variables that were studied. We believe that the differences in preoperative and postoperative SPB levels could be attributed to alveolocapillary membrane damage and alveolar surfactant dysfunction. We found that this pathophysiological condition was significantly associated with postoperative parameters. CONCLUSION: The findings of the current study showed that surfactant protein B was present in the blood of patients with a congenital heart disease during the preoperative period. Long by-pass times may exert damage to the alveolocapillary membrane in patients with pulmonary hypertension and preoperative heart failure, and it is recommended to keep the option of surfactant therapy in mind during the postoperative course at the intensive care unit before preparing the patients for extubation.

Objetivo: As cardiopatias congênitas são observadas em 5 a 8 em cada 1.000 nascidos vivos. A presença de um biomarcador importante durante os períodos cirúrgicos pode auxiliar o clínico a um prognóstico mais preciso durante o tratamento. Métodos: Por esta razão, os níveis plasmáticos de proteína B do surfactante podem ajudar a avaliar os pacientes com problemas cardíacos, diminuindo a estabilidade da membrana alvéolo-capilar. Neste estudo, os níveis plasmáticos deste biomarcador foram medidos nos períodos pré-operatório e pós-operatório. Este estudo foi realizado para detectar as diferenças entre pacientes hipertensos e normotensos em nível pulmonar. As diferenças antes e depois da circulação extracorpórea foram examinadas. Resultados: As diferenças no tempo de circulação extracorpórea, tempo de pinçamento, a dose de drogas vasoativas, e a duração da terapia intensiva de pacientes com e sem hipertensão pulmonar foram estatisticamente significativas (P<0,05). Os resultados revelaram que este estado fisiopatológico foi relacionado a outras variáveis que foram estudadas. Acreditamos que as diferenças nos níveis de SPB pré-operatório e pós-operatório pode ser atribuída a danos na membrana alvéolo-capilar e disfunção do surfactante alveolar. Descobrimos que esta condição fisiopatológica foi significativamente associada com parâmetros pós-operatórios. Conclusão: Os resultados do estudo mostraram que a proteína B surfactante estava presente no sangue de pacientes com doença cardíaca congênita no pré-operatório. Longos tempos de circulação extracorpórea podem exercer danos na membrana alvéolo-capilar em pacientes com ...
