RESUMO
BACKGROUND: The aim of this study was to compare the early results of rapid deployment aortic valves (RD-AVR) and aortic valve neocuspidization (AVNeo) techniques. METHODS: Between December 2019 to May 2022, 104 patients were operated on with aortic stenosis by RD-AVR (N = 52) and AVNeo (N = 52) techniques. Patients with isolated aortic valve stenosis and aortic stenosis concomittant with planned other cardiac surgeries were included. RESULTS: The mean age of patients in the RD-AVR and AVNeo groups were 67.4 ± 7.8 vs. 62.9 ± 8.7, respectively. Aortic cross-clamp time in the RD-AVR group was 56.7 ± 23.3 minutes, while it was 104.1 ± 27.9 minutes in the AVNeo group (P < 0.001). Cardiopulmonary bypass time in the RD-AVR group and in the AVNeo group was 89.8 ± 27.6 minutes and 141.8 ± 36.7 minutes, respectively (P < 0.001). Permanent pacemaker become necessary in four patients in the RD-AVR group secondary to type 2 AV block. Paravalvular leak was observed in six patients, who underwent RD-AVR, while grade 2 central aortic regurgitation was observed in one patient in the AVNeo group. Hospital mortality was 8% in the RD-AVR group and 6% in the AVNeo group (P = 0.696). CONCLUSIONS: AVNeo procedure is a feasible technique in all age groups of patients with successful hemodynamic results in the early postoperative period and with the advantage of not requiring anticoagulants. It also can be applied with other cardiac surgical interventions.

INTRODUCTION: Robotic mitral valve surgery is a challenging issue, particularly in patients who are not suitable for aortic cross-clamping. In this study, we aimed to determine the feasibility and benefits of robotic, beating heart mitral valve surgery. METHODS: From February 2019 to February 2022, 17 patients underwent robotic beating heart mitral valve surgery. Fourteen of the patients had previous cardiac surgery. The mean age was 58.1 ± 10.3. Dense periaortic adhesions, heavily calcified aorta, and low ejection fraction were retained as indications for beating heart surgery. RESULTS: Mitral valve replacement was performed in 14 patients. Mitral ring annuloplasty was performed in two patients with low ejection fraction (EF). A severe paravalvular leak was repaired in one patient. Additional tricuspid annuloplasties were performed in three patients. Cardiopulmonary bypass time were 185.6 ± 55 min. There were no cases of conversion to sternotomy or thoracotomy. No cerebrovascular event occurred in the follow-up. One patient died as a result of secondary hepatorenal syndrome and multiorgan failure. CONCLUSIONS: Robotic beating heart mitral valve surgery is a feasible and effective technique with favorable early and mid-term results, especially in patients who are not suitable for aortic cross-clamping, secondary to periaortic adhesions, severe aortic calcifications, and low ejection fraction.

BACKGROUND: Robotic mitral valve surgery continues to become widespread all over the world in direct proportion to the developing technology. In this study, we aimed to compare the postoperative results of robotic mitral valve replacement and conventional mitral valve replacement. METHODS: A total of consecutive 130 patients who underwent robotic mitral valve replacement and conventional mitral valve replacement with full sternotomy between 2014 and 2020 were included in our study. All patients were divided into two groups: Group I, with 64 patients who underwent robotic mitral valve replacement and Group II, with 66 patients with conventional full sternotomy. General demographic data (age, gender, body weights, etc.), comorbidities (hypertension, diabetes mellitus, chronic obstructive pulmonary disease, peripheral artery disease, hyperlipidemia, etc.), intraoperative variables (cardiopulmonary bypass times, and cross-clamp times), postoperative ventilation times, drainage amounts, transfusion amount, inotropic need, revision, arrhythmia, intensive care and hospital stay times, and mortality were analyzed retrospectively. RESULTS: There was no significant difference between demographic data, such as age, gender, body kit index, and preoperative comorbid factors of both patient groups (p > .05). Cardiopulmonary bypass time (204.12 ± 45.8 min) in Group I was significantly higher than Group II (98.23 ± 17.8 min) (p < .001). Cross-clamp time in Group I (143 ± 27.4 min) was significantly higher than Group II (69 ± 15.2 min) (p < .001). Drainage amount in Group I (290 ± 129 cc) was significantly lower than Group II (561 ± 136 cc) (p < .001). The erythrocyte suspension transfusion requirement was 0.4 ± 0.3 units in Group I; it was 0.9 ± 1.2 units in Group II, and this requirement was found to be significantly lower in Group I (p = .014). While the mean mechanical ventilation time was 5.3 ± 3.9 h in Group I, it was 9.6 ± 4.2 h in Group II. It was significantly lower in Group I (p = .001). Accordingly, intensive care stay (p = .006) and hospital stay (p = .003) were significantly lower in Group I. In the early postoperative period, three patients in Group I and four patients in Group II were revised due to bleeding. In the postoperative hospitalization period, neurological complications were observed in one patient in Group I and two patients in Group II. Two patients in Group I returned to the sternotomy due to surgical difficulties. Two patients died in both groups postoperatively, and there was no significant difference in mortality (p = .97). CONCLUSION: According to conventional methods, robotic mitral valve replacement is an effective and reliable method since total perfusion and cross-clamp times are longer, drainage amount and blood transfusion need are less, and ventilation time, intensive care, and hospital stay time are shorter.

BACKGROUND: This study aimed to investigate the incidence of postoperative atrial fibrillation (POAF) in patients undergoing off-pump versus on-pump coronary artery bypass grafting (CABG) under cardiopulmonary bypass (CPB). METHODS: A total of 3,197 consecutive patients (1,816 males, 1,381 females; mean age: 60.8 ± 9.8 years) with preoperative sinus rhythm who underwent CABG at a cardiovascular surgery clinic between November 2009 and March 2014 retrospectively were analyzed. Of the patients, 1,680 underwent on-pump and 1,517 underwent off-pump cardiac surgery. Data, including demographic characteristics, preoperative risk factors, preoperative medications, laboratory test results, postoperative data and complications, and mortality and morbidity rates, were recorded. RESULTS: According to the multivariate analysis, the type of operation, number of anastomoses, right coronary artery or right coronary posterior descending artery graft, vasopressor therapy (epinephrine, norepinephrine), operation duration, age >60 years, hypertension, length of hospital stay >4 days, and obstructive sleep apnea syndrome (OSAS) were the independent predictors of POAF after CABG. Our study results suggest that on-pump CABG under CPB is correlated with POAF. CONCLUSION: We recommend using off-pump CABG in select cases to minimize the risk of POAF.

BACKGROUND: This study aimed to investigate the predictive significance of C-reactive protein/albumin ratio for postoperative atrial fibrillation occurrence in patients who were underwent coronary artery bypass graft surgery. METHODS: Among 830 patients who underwent coronary artery bypass grafting with cardiopulmonary bypass between January 2016 and February 2020, 137 patients with no prior arrhythmia history were included in this cross sectional study. RESULTS: One hundred and thirty-seven (16.5%) patients developed atrial fibrillation in postoperative period. Patients who experienced postoperative atrial fibrillation were more likely to be older but displayed similar rates of diabetes mellitus, hypertension, hypercholesterolemia, cerebrovascular disease, peripheral vascular disease and chronic obstructive pulmonary disease. For prediction of postoperative atrial fibrillation development, diagnostic odds ratio (OR) and positive likelihood ratio of C-reactive protein/albumin ratio value (OR: 1.854; confidence interval [CI]: 1.598-2.142; P < .001) was higher than serum C-reactive protein and albumin levels. (OR: 1.159; CI: 1.115-1.201; P < .001; OR: 0.438; CI: 0.258-0.865; P < .001, respectively). Which means that C-reactive protein/albumin ratio may detect postoperative atrial fibrillation development better C-reactive protein itself. CONCLUSION: Based on our results, patients who developed postoperative atrial fibrillation after coronary artery bypass grafting had significantly higher preoperative C-reactive protein/albumin ratio levels than patients who remained in normal sinus rhythm in the postoperative period. Also, higher C-reactive protein/albumin ratio value was one of the independent predictive factors for postoperative atrial fibrillation. Therefore, we concluded that evaluating preoperative C-reactive protein/albumin ratio value might provide early identification of patients with high risk for postoperative atrial fibrillation.

Left ventriculotomy for thrombus removal is usually associated with a high incidence of cardiac arrhythmias and decreased ejection fraction. A 51-year-old male patient was admitted to the emergency department with loss of consciousness. Transthoracic echocardiography revealed a 20 × 24-mm left ventricular apical nonpedunculated thrombus with normal ejection fraction. A persistent thrombus was shown on magnetic resonance imaging despite anticoagulation therapy. Robotic surgery was planned to avoid possible ventriculotomy-related complications, considering the preoperative neurological condition of the patient. The thrombus was completely removed surgically through left atriotomy using the DaVinci robotic system. In conclusion, robotic surgery can be used in the surgical treatment of left ventriculotomy thrombus in selected patients.

Myocardial ischemia-reperfusion injury continues to be observed during open heart surgery. Various experimental models have been developed to overcome this injury and to increase postoperative prognosis. This study was conducted to assess the effect that iloprost, a prostacyclin analogue, can have on myocardial ischemia-reperfusion injury. We evaluated tissue damage by measuring the levels of malonyldialdehyde (MDA), glutathione, and nitric oxide (NO) in tissue and perfusates. In this study, 20 guinea pig hearts were prepared by using the modified Langendorff perfusion apparatus to form control (n = 10) and experimental study groups (n = 10). Following a preischemic period of perfusion and an ischemic period of 20 minutes, control hearts were perfused with KrebsHenseleit solution. In the experimental group, iloprost (0.45 µg/kg per hour) was included in the perfusates for the last 10 minutes of the preischemic phase. Following cardiac stabilization, heart rate (pulse/min), contractility (mm), and aortic pressure (mmHg) values were recorded at the end of preischemia, postischemia, and reperfusion. Perfusate and tissue analyses for glutathione, MDA, and NO levels were made in each group at the end of experiments. Iloprost was found to have protective effects against myocardial ischemia by means of increased myocardial contractility, decreased tissue/perfusate glutathione levels and inhibited rise of tissue/perfusate MDA observed in the iloprost-treated experimental group. Future investigations on myocardial ischemia-reperfusion injury must evaluate iloprost-related mechanisms.

INTRODUCTION: Partial pulmonary venous return anomalies (PPVRA) were not considered as a good candidate for robotic surgery in early time of robotic cardiac surgery. In this study, we present our experience in patients undergoing robotic atrial septal defect (ASD) and PPVRA surgery. METHODS: Between November 2014 and January 2020, data of 21 patients underwent robotic ASD with PPVRA was collected. Inclusion criterion was presence of right-sided PPVRA with ASD. All operations were performed robotically. RESULTS: The mean age of patients was 26.7 ± 10.3 years. Seventeen patients (81%) had superior-caval ASD with supracardiac PPVRA and double-patch technique was used. Four patients had inferior-caval ASD with intracardiac PPVRA and single-patch technique was preferred. Cross-clamp time and cardiopulmonary bypass time were 92.8 ± 29.6 and 127.8 ± 38.1, respectively. There was no mortality. One patient had atrioventricular-block and required pacemaker. CONCLUSION: Robotic repair of ASD with PPVRA is feasible and effective method as an alternative to conventional surgery.

Redo-cardiac surgery is associated with high morbidity and mortality rates. Although redo surgery are relative contraindications for robotic surgery, robotic redo mitral valve surgery has been performed with endo-aortic occlusion techniques and on fibrillated heart successfully. Beating heart mitral valve surgery is another well-known option for redo cardiac surgery practice. Robotic beating heart surgery is not well-studied before. As a new point of view to robotic reoperation surgery, herein, we aimed to present a case who underwent redo robotic mitral valve replacement combined with dysfunctioned amplatzer plug resection on a beating heart.
RESUMO
BACKGROUND: In this study, the effects of pulsatile and non-pulsatile on-pump Coronary Artery Bypass Graft surgery (CABG) and off-pump CABG techniques on the intraocular pressure were investigated. METHODS: Forty-five patients who planned to elective coronary artery bypass surgery with on-pump pulsatile (n=15), non-pulsatile (n=15), or off-pump (n=15) were included. Intraocular Pressure (IOP) measurements were performed on both eyes at nine time-points: 1) Before the operation, 2) After anesthesia induction, 3) 3 minutes after heparin administration Left Internal Mammary Artery (LIMA) harvesting, 4) End of the first anastomosis, 5) End of LIMA anastomosis, 6) 3 minutes after protamine administration, 7) End of the operation, and 8) Second hour in Intensive Care Unit (ICU), 9) Fifth hour in ICU. Mean Arterial Pressure (MAP) and Central Venous Pressure (CVP) were also recorded at the same time points as IOP. RESULTS: In Cardiopulmonary Bypass (CPB) groups (pulsatile or non-pulsatile CPB) with the beginning of CPB, there were significant decreases in IOP values when compared to baseline (p=0.012). This decrease was more prominent in the non-pulsatile group when compared to the pulsatile group (T4 IOP values: pulsatile, 9.7±2.6; non-pulsatile, 6.8±1.9; p=0.002; T5 IOP values: pulsatile, 9.5±1.9; non-pulsatile, 6.7±2.1; p=0.004). At the end of the surgery (T7), IOP values returned to the baseline and stayed stable at the remaining time-points. In-off pump group, IOP values significantly increased with a head-down position (T4 IOP values: off-pump surgery, 19.7±5.2; p=0.015). IOP values remained high until the normalization of head-down position (T6) and stayed stable through the rest of all remaining time-points. CONCLUSION: During cardiac surgery regardless of the technique (on-pump CABG, off-pump CABG), intraocular pressures remain in the normal ranges. It should be kept in mind that patients should be avoided from long and extreme Trendelenburg position, low CVP, and MAP levels during cardiac surgery to prevent eye-related complications.

OBJECTIVE: Atrial fibrillation (AF) is the most common arrhythmia, which is also associated with mitral valve disease. Surgical ablation is still known to be an important procedure in restoring sinus rhythm (SR) concomitant with mitral valve surgery (MVS). In this study, we aimed to pres-ent our early- and mid-term result of AF cryoablation during robotic MVS. METHODS: Between November 2014 and January 2020, total 34 patients who underwent robotic MVS with concomitant AF ablation were ret-rospectively analyzed. Ten patients had a <1 year AF history, 14 had 1-5 years, and 10 had >5 years. The primary end point of the study was postoperative AF recurrence. RESULTS: Total 32 and 2 patients underwent mitral valve replacement and mitral valve repair, respectively. Mean aortic cross-clamp and cardio-pulmonary bypass times were 141.8±32.1 min and 196±25.6 min, respectively. The SR was restored with the removal of cross-clamp and cardiac junctional rhythm was observed in 29 (85.3%) and 5 (14.7%) patients, respectively. Two in-hospital deaths secondary to low cardiac output and hepatorenal failure were recorded. Among the rest, 24 (75%) patients were in SR, 6 (18.75%) in AF, and 2 (6.25%) in paced rhythm at discharge. CONCLUSION: Robotic cryoablation of AF during MVS is a feasible method with favorable early- and mid-term results.

N-acetylcysteine (NAC) is an antioxidant which works as a free radical scavenger and antiapoptotic agent. N-acetylcysteine-amide (NACA) is a modified form of NAC containing an amide group instead of a carboxyl group of NAC. Our study aims to investigate the effectiveness of these two substances on erythrocyte deformability and oxidative stress in muscle tissue. Materials and Methods. A total of 24 Wistar albino rats were used in our study. The animals were randomly divided into five groups as control (n: 6), ischemia (n: 6), NAC (n: 6), and NACA (n: 6). In the ischemia, NAC, and NACA groups, 120 min of ischemia and 120 min of reperfusion were achieved by placing nontraumatic vascular clamps across the abdominal aorta. The NAC and NACA groups were administered an injection 30 min before ischemia (100 mg/kg NAC; 100 mg/kg NACA; intravenous). Blood samples were taken from the animals at the end of the ischemic period. The lower extremity gastrocnemius muscle was isolated and stored at -80 degrees to assess the total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values and was analyzed. Results. The erythrocyte deformability index was found to be statistically significantly lower in rats treated with NAC and NACA before ischemia-reperfusion compared to the groups that received only ischemia-reperfusion. In addition, no statistically significant difference was found between the control group and the NAC and NACA groups. The groups receiving NAC and NACA before ischemia exhibited higher total antioxidative status and lower total oxidative status while the oxidative stress index was also lower. Conclusion. The results of our study demonstrated the protective effects of NAC and NACA on erythrocyte deformability and oxidative damage in skeletal muscle in lower extremity ischemia-reperfusion. NAC and NACA exhibited similar protective effects on oxidative damage and erythrocyte deformability.
RESUMO
Pneumomediastinum is a rare entity that is defined as free air in the mediastinal space. A 26-year-old male patient was admitted with pneumomediastinum as an unexpected complication of robotic surgery. Diffuse subcutanous emphysema was observed suddenly on Postoperative Day 3 without respiratory distress. Air trapping into the mediastinum was seen on chest X-ray and computed tomography. The patient was followed in the intensive care unit for 7â¯days and managed conservatively. Subcutaneous emphysema reduced gradually. In conclusion, although it is a rare condition, pneumomediastinum should be kept in mind as a complication of robotic cardiac surgery.
RESUMO
BACKGROUND: Assessing therapeutic efficacy and patient satisfaction objectively and quantitatively has always been a problem in patients with vasospastic disorders. We aimed to present the additive value of ultrasonographic assessment of peripheral arteries secondary to cold stimulation, as a test for treatment efficacy during follow-up. MATERIAL AND METHODS: Arterial blood flow rates were measured from radial artery with Doppler USG in patients who presented to our department with vasospastic disorders. Ultrasonography was performed at the following intervals; before cold stimulation and at 5th, 10th, 15th, 20th minutes of cold stimulation. Patients were controlled by repeat cold stimulation test and Doppler US at the 2nd month of the treatment. Results were analyzed with SPSS for Mac 20.0 package program. RESULTS: We enrolled 46 patients in the study. All patients were male and mean age was 22.3 ± 2.17 years. Most common symptoms were cyanosis and coldness. There were statistically significant differences between pre-treatment and post-treatment arterial blood flow rates at each measurement time point (p<0.001) except initial measurement (p>0.05). On post-treatment values, there were 10.04±0.78 cm/s increase in 5th minute, 6.25 ± 1.39 cm/s in 10th minute, 6.43 ± 2.13 cm/s in 15th minute, and 6.38 ± 1.86 cm/s in 20th minute measurements. All increases at the 5 time points were statistically meaningful when compared to their pre-treatment corresponding time points (p<0.001). CONCLUSIONS: Doppler flowmetry added to standard cold stimulation test for evaluating the patients with vasospastic disorders provides better and more objective results when compared to the patient-oriented subjective scoring systems.

BACKGROUND Raynaud phenomenon (RP) is common worldwide and presents diagnostic and therapeutic difficulties. We aimed to share our experience with optimizing of patient follow-up by using the cold-stimulation test (CST). MATERIAL AND METHODS Data of 81 patients admitted with RP symptomatology were collected. Demographic data and symptoms were recorded. A scale was used for determining the severity of disease at pre-treatment and post-treatment. CST was performed to all patients at pre-treatment and post-treatment for assessment of treatment efficiency in follow-up. Results were analyzed with the SPSS for Mac 20.0 program. RESULTS All the patients were male. Mean age was 22.3 ± 2.14 (19-29). Mean duration of symptoms from onset to present was 4.59 ± 2.85 years. There were statistically significant differences between pre-treatment and post-treatment hand temperatures measured by CST (p<0.001). However, there were no statistically significant differences between pre-treatment and post-treatment severity scores of patients (p=0.135). CONCLUSIONS To quantitatively determine the treatment efficacy, CST may be used instead of asking simple questions of patients.

Intravenous leiomyomatosis (IVL) is a rare neoplasm characterized by histologically benign-looking smooth muscle cell tumor mass, which is growing within the intrauterine and extrauterine venous system. In this report we aimed to present an unusual case of IVL, which is originating from iliac vein and extended throughout to right cardiac chambers. A 49-year-old female patient, who was treated with warfarin sodium due to right iliac vein thrombosis, was admitted to our department with intermittent dyspnea, palpitation, and dizziness. Physical examination was almost normal except bilateral pretibial edema. On magnetic resonance venography, there was an intravenous mass, which is originated from right internal iliac vein and extended into the inferior vena cava. Transthoracic echocardiography and transesophageal echocardiography revealed a huge mass extending from the inferior vena cava through the right atrium, with obvious venous occlusion. Thoracic, abdominal, and pelvic MR showed an intravascular mass, which is concordant with leiomyomatosis. Surgery was performed through median sternotomy. A huge mass with 25-cm length and 186-gr weight was excised through right atrial oblique incision, on beating heart with cardiopulmonary bypass. Histopathologic assessment was compatible with IVL. Exact strategy for the surgical treatment of IVL is still controversial. We used one-stage approach, with complete resection of a huge IVL extending from right atrium to right iliac vein. In such cases, high recurrence rate is a significant problem; therefore it should be kept in mind.
RESUMO
BACKGROUND Vasospastic disorders are common worldwide. In daily practice, routine blood samples are used for several investigations. In this study we aimed to determine the possible correlations between lymphocyte count, platelet indices, and the severity of vasospastic disorders. MATERIAL AND METHODS Data of 102 patients admitted to our department with vasospastic disorder symptomatology were retrospectively collected. Demographic data, symptoms, and blood test results were recorded. Patients were divided into 2 groups according to their rewarming time, which is determined by the cold stimulation test. Group 1 consisted of patients with rewarming time below 20 min and Group 2 consisted of patients with rewarming time above 21 min. Demographic data and blood test results were compared between groups. Results were analyzed with the SPSS for Mac 20.0 package program. RESULTS There was no statistically significant difference between the groups in demographic variables and symptomatology. In Group 2, mean platelet volume (MPV) and platelet distribution width (PDW) were higher than in Group 1, which was statistically significant (8.87 ± 0.74 vs. 8.38 ± 0.78, p=0.001 and 15.91 ± 1.92 vs. 14.7 ± 1.99, p=0.002, respectively). Similar to MPV and PDW, lymphocyte count was also higher in Group 2 than in Group 1 (2.28 ± 0.65 vs. 1.90 ± 0.68, p=0.002). CONCLUSIONS Diagnosis and grading the severity of VD is challenging, but it can be supported by the presence of increased PDW, MPV, and lymphocyte count.

BACKGROUND: We aimed to examine the effects of topical hypothermia on inflammatory markers in patients undergoing coronary artery bypass surgery. METHODS: Fifty patients undergoing isolated coronary artery bypass surgery were included the study. They were randomised to two groups. Mild hypothermic cardiopulmonary bypass (28-32°C) was performed on both groups using standardised anaesthesiology and surgical techniques. Furthermore, topical cooling with 4°C saline was performed on patients in group I. We recorded peri-operative and intra-operative results of blood samples, pre-operative and postoperative outcomes of electrocardiography and echocardiography, diaphragm levels on X-ray, and the necessity of positive inotropic medication and intra-aortic balloon pump (IABP). RESULTS: Time-dependent changes in blood samples were compared between the two groups. The changes on complement 3 (C3) and TNF-α levels were more significant in group I than group II (p < 0.05 and p < 0.001, respectively). Spontaneous restoration rate of sinus rhythm was higher in group II than group I (80 vs 32%, p < 0.01). Atrial fibrillation was seen in six patients in group I and one patient in group II (p < 0.05). IABP was performed on four patients (16%) in group I (p < 0.05). Diaphragmatic paralysis was seen in seven patients in group I but not in group II (p < 0.01). Partial pericardiotomy rates were compared within the groups but there was no statistically significant difference (p > 0.05). One patient in group I died on the 18th postoperative day, but operative mortality rate was not statistically significant between the two groups (p > 0.05). CONCLUSIONS: Topical hypothermia had a negative impact on inflammatory markers and postoperative morbidities.
