The Effect of Perioperative Fluid Management and Operative Modifications on Mortality and Morbidity in Patients Undergoing Pulmonary Endarterectomy.

INTRODUCTION: Chronic thromboembolic pulmonary hypertension (CTEPH) is a severe disease treated with pulmonary endarterectomy. Our study aims to reveal the differences in liquid modalities and operation modifications, which can affect the patients' mortality and morbidity. METHODS: One hundred twenty-five patients who were diagnosed with CTEPH and underwent pulmonary thromboendarterectomy (PTE) at our center between February 2011 and September 2013 were included in this retrospective study with prospective observation. They were in New York Heart Association functional class II, III, or IV, and mean pulmonary artery pressure was > 40 mmHg. There were two groups, the crystalloid (Group 1) and colloid (Group 2) liquid groups, depending on the treatment fluids. P-value < 0.05 was considered statistically significant. RESULTS: Although the two different fluid types did not show a significant difference in mortality between groups, fluid balance sheets significantly affected the intragroup mortality rate. Negative fluid balance significantly decreased mortality in Group 1 (P<0.01). There was no difference in mortality in positive or negative fluid balance in Group 2 (P>0.05). Mean duration of stay in the intensive care unit (ICU) for Group 1 was 6.2 days and for Group 2 was 5.4 days (P>0.05). Readmission rate to the ICU for respiratory or non-respiratory reasons was 8.3% (n=4) in Group 1 and 11.7% (n=9) in Group 2 (P>0.05). CONCLUSION: Changes in fluid management have an etiological significance on possible complications in patient follow-up. We believe that as new approaches are reported, the number of comorbid events will decrease.

The impact of COVID-19 pandemic on congenital heart surgery practice: An alarming change in demographics.

BACKGROUND: The aim of this study is to investigate the effect of COVID-19 outbreak on congenital cardiac surgery practice in a single center. METHODS: The first case of COVID-19 in our country was seen on March 11th, 2020. The patients operated between March 11th, 2019-and March 10th, 2020 were taken as the pre-COVID group, and those operated between March 11th and May 11th, 2020 were taken as the COVID group. The data was retrospectively collected, and the two periods were compared. RESULTS: Monthly average number of cases which was 52 patients/month (626 patients in 12 months) before COVID decreased to 35 patients/month (70 patients in 2 months) during COVID periods (P < .01). During the pre-COVID period the median postoperative length of hospital stay was 3 (IQR: 1-5) days. During the COVID period, this decreased to 1 (IQR: 1-3) day (P < .01). During the pre-COVID period, the hospital expenses of 17% (8/47) of the foreign nationals were covered by their homeland. The remaining 83% (39/47) were paid from the asylum seekers' fund. The proportion of foreign nationals operated significantly decreased during the COVID period ([7%; 47/632 vs 1%; 1/70]; P = .04). No significant difference was observed in terms of STAT mortality scores and categories and postoperative results of the operations performed between the two periods. CONCLUSIONS: Congenital cardiac surgery practice can be safely maintained with restricted case volume during the pandemic period. It is alarming that patients in the deprived areas cannot access pediatric cardiac surgery and possibly other health services because of closure of the borders between countries.

Neutrophil/Lymphocyte Ratio Can Predict Postoperative Mortality in Patients with Chronic Thromboembolic Pulmonary Hypertension.

OBJECTIVE: The aim of our study was to investigate clinical importance of neutrophil/ lymphocyte ratio in patients with Chronic thromboembolic pulmonary hypertension. METHODS: 125 consecutive patients with a diagnosis of Chronic thromboembolic pulmonary hypertension were operated pulmonary thromboendarterectomy in our center between February 2011 and August 2013. 106 patients included into the study due to limitations. The patients were classified into two groups as patients discharged alive (Group 1) and those dying in the hospital (Group 2). Baseline neutrophil/lymphocyte ratio level was measured by dividing neutrophil count to lymphocyte count. RESULTS: 84 patients (79%) were in Group 1, 22 patients (21%) were in Group 2. Patients with higher neutrophil/lymphocyte ratio in admission have a significantly higher mortality rate and postoperative pulmonary vascular resistance was found statistically significant variable to predict the mortality. Receiver operator characteristic (ROC) analysis revealed that using a cut-off point of 2.54, admission neutrophil/lymphocyte ratio predicts mortality. Also, correlation analysis showed a significant correlation between preoperative pulmonary vascular resistance and neutrophil/lymphocyte ratio. CONCLUSION: The neutrophil/lymphocyte ratio level may be a useful and noninvasive biomarker for operative risk stratification for mortality after pulmonary thromboendarterectomy.

Right ventricular mass: intracardiac ectopic thyroid tissue: a case report.

Ectopic thyroid tissue is a result of abnormal migration of thyroid tissue during the embryonic state. Most of these rare cases, almost 90% of them, are located in the base of the tongue and a minority of them is located anteriorly near the hyoid bone area. Below we report the case of a young patient with an intracardiac mass first diagnosed with three-dimensional echocardiography and afterward successfully treated surgically. Once a careful histological examination has revealed a follicular adenoma, the prognosis is good especially if successful surgical excision is part of the management.

Comparison of superior septal approach with left atriotomy in mitral valve surgery.

OBJECTIVE: In this study, we aimed to compare clinical outcomes of superior transseptal approach with the conventional left atriotomy in patients undergoing mitral valve surgery. METHODS: Between January 2010 and November 2012, a total of 91 consecutive adult patients (39 males, 52 females; mean age: 54.0±15.4 years; range, 16 to 82 years) who underwent mitral valve surgery in the Division of Cardiovascular Surgery at Kosuyolu Training Hospital were included. The patients were randomized to either superior transseptal approach (n=47) or conventional left atriotomy (n=44). Demographic characteristics of the patients, comorbidities, additional interventions, intraoperational data, pre- and postoperative electrophysiological study findings, and postoperative complications were recorded. RESULTS: Of all patients, 86.7% (n=79) were in New York Heart Association Class III, while 12 were in New York Heart Association Class IV. All patients underwent annuloplasty (42.9%) or valve replacement surgery (57.1%). There was no significant difference in pre- and postoperative electrocardiogram findings between the groups. Change from baseline in the cardiac rhythm was statistically significant in superior transseptal approach group alone (P<0.001). There was no statistically significant difference in mortality rate between the groups. Permanent pacemaker implantation was performed in 10.6% of the patients in superior transseptal approach group and 4.5% in the conventional left atriotomy group. No statistically significant difference in bleeding, total length of hospital and intensive care unit stay, the presence of low cardiac output syndrome was observed between the groups. CONCLUSION: Our study results suggest that superior transseptal approach does not lead to serious or fatal adverse effects on sinus node function or atrial vulnerability, compared to conventional approach.
