First worldwide use of the hybrid system for extracorporeal circulation in heart transplant.

BACKGROUND: This case report documents the first worldwide use of the Hybrid System from Spectrum Medical in a heart transplant procedure, focusing on its safety and efficacy. Traditional cardiopulmonary bypass systems often use an open reservoir, which increases the blood's exposure to air, thereby heightening the risk of an inflammatory response and gas embolism. In contrast, the Hybrid System is designed to improve surgical outcomes by significantly reducing the blood-air interface. This system utilizes a dual-chamber cardiotomy-venous reservoir with a collapsible soft bag, effectively minimizing blood contact with air and foreign materials. However, it is important to note that there is currently no evidence supporting the use of this methodology specifically in heart transplants. CASE PRESENTATION: A 41-year-old male managed with a left ventricular assist device because of dilated cardiomyopathy underwent a heart transplant using the Hybrid System. The perioperative and postoperative data provided evidence of the system's effectiveness. The selection of this patient was due to the absence of significant comorbidities unrelated to his primary cardiac condition, making him an ideal candidate to evaluate the system's performance. CONCLUSION: The Hybrid System is safe and efficient. The successful implementation in this case highlights its advantages over traditional cardiopulmonary bypass systems, suggesting a promising future in cardiac surgery. Further studies with routine cardiac surgery patients are required to validate these findings.

Comparison of minimal invasive extracorporeal circulation versus standard cardiopulmonary bypass systems on coronary artery bypass surgery.

Background: In this study, we shared our experience with the minimal invasive extracorporeal circulation system for coronary artery bypass grafting patients. Methods: A total of 163 patients were included in the retrospective study, with 83 patients (63 males, 20 females; mean age: 61.9±8.9 years; range, 35 to 81 years) undergoing coronary artery bypass grafting with minimal invasive extracorporeal circulation and 80 patients (65 males, 15 females; mean age: 60.5±8.8 years; range, 43 to 82 years) undergoing coronary artery bypass grafting with conventional cardiopulmonary bypass between July 2021 and April 2023. Elective coronary bypass performed by same surgical team were included in the study. Mortality, major adverse cardiac and cerebrovascular event, hospital stays and transfusion requirements were evaluated. Results: There were no significant differences in sex distribution, age, comorbidities, and blood values between the two groups. Intraoperatively, the minimal invasive extracorporeal circulation group had a slightly higher number of distal anastomoses and comparable times for aortic cross-clamp and cardiopulmonary bypass. Postoperative outcomes such as tamponade, bleeding, atrial fibrillation, left ventricular ejection fraction improvement or reduction, and postoperative drainage were similar between the two groups. However, the minimal invasive extracorporeal circulation group had fewer transfusions of packed red blood cells and fresh frozen plasma and a shorter length of stay in the intensive care unit. Conclusion: The minimal invasive extracorporeal circulation system effectively preserves blood, works with lower activated clotting time values without additional complications in coronary artery bypass grafting, and could present a better option for patients with anemia or patients with a relatively high risk for high-dose heparinization.

Outcomes of conservative management in patients with nutcracker syndrome.

OBJECTIVE: This study aims to evaluate outcomes in nutcracker syndrome patients with tolerable symptoms and treated conservatively without invasive interventions. METHODS: This prospective study included patients treated conservatively. Promoting weight gain, the endpoint of the study was spontaneous resolution of symptoms. RESULTS: Sixteen patients (75% female and mean age 24.4 ± 3.5 years) underwent conservative management. Over a mean follow-up of 27.3 months [13-42, interquartile range (IQR)], the diameter ratio (5.5 [5-6.5, IQR] vs 4.3 [4.1-6], p = NS), the peak velocity ratio (6 [5-7, IQR] vs 4.8 [4.8-5.8], p = NS), beak angle (27° [24-30, IQR] vs 29° [24-32]; p = NS), and aortomesenteric angle (26° [23-29, IQR] vs 28° [24-30]; p = NS) exhibited no statistically significant changes. Complete resolution and improvement of symptoms were 28.5% and 31.4%, respectively, while 68.5% remained unchanged. CONCLUSIONS: This study shows that a conservative approach contributes to the spontaneous improvement or complete resolution in young adult patients with mild symptoms.

Treatment of Nutcracker Syndrome with Left Renal Vein Transposition and Endovascular Stenting.

BACKGROUND: Nutcracker syndrome is a rare condition that occurs as a result of the entrapment of the left renal vein (LRV) between the aorta and the superior mesenteric artery. It is typically associated with symptoms such as left flank pain, hematuria, proteinuria, and pelvic congestion. The current treatment approach may be conservative in the presence of tolerable symptoms, and surgical or hybrid and stenting procedures in the order of priority in the presence of intolerable symptoms. The aim of this study is to review our experiences to evaluate the results of both methods in this series in which we have a greater tendency toward surgery instead of stenting. METHODS: The clinical data of consecutive patients with nutcracker syndrome who underwent LRV transposition and LRV stenting between July 2019 and October 2023 were retrospectively reviewed. The patients were divided into 2 groups based on the methods of treatment: surgical and stenting. For procedure selection, LRV transposition was primarily recommended, with stenting offered to those who declined. Primary end points were morbidity and mortality. Secondary end points included late complications, patency, freedom from reintervention, and resolution of symptoms. Standard basic statistics and survival analysis methods were employed. RESULTS: Nineteen patients with nutcracker syndrome (female: 100%) were treated with LRV stentings (n = 5) and LRV transposition (n = 14). The mean age was 24 (20-27, interquartile range [IQR]) years. The mean follow-up was 23 (9-32, IQR) months. There were no major complications and mortality after both procedures. The most frequent sign and symptom associated with LRV entrapment were left flank pain 100% (n = 19), proteinuria 88% (n = 15), and hematuria 47% (n = 9). The mean peak velocity ratio on Doppler ultrasound was 6.13 (6-6.44, IQR). Aortomesenteric angle, beak angle (beak sign), and mean diameter ratio on computed tomography were 26° (22.6-28.5, IQR), 25° (23.9-28, IQR), and 5.3 (5-6, IQR), respectively. Venous pressure measurements were only used to confirm the diagnosis in 5 patients in the stenting group. The measured renocaval gradient was 4 (3.9-4.4, IQR) mm Hg. After both procedures, the classical symptoms, including left flank pain, proteinuria, and hematuria, resolved in 89.5% (n = 17), 57.8% (n = 11), and 82.3% (n = 15) of the cases, respectively. A total of 4 patients required reintervention, 3 patients after LRV transposition (occlusion, n = 2; stenosis, n = 1), and 1 patient after stenting (occlusion, n = 1). The 1-year and 3-year primary patency for the 19 patients was 87% and 80%, respectively. Three-year primary-assisted patency was 100%. Similarly, the 1-year and 3-year freedom from reintervention rate was 83% and 72%, respectively. Additionally, the 1-year and 3-year primary patency for the surgical group was 91% and 81%, respectively, and the 1-year and 3-year primary patency for the stenting group was 75%. CONCLUSIONS: Nutcracker syndrome should be kept in mind in cases where flank pain and hematuria cannot be associated with kidney diseases. Radiographic evidence must be accompanied by serious symptoms to initiate the treatment of nutcracker syndrome with LRV transposition and endovascular stenting procedures. Both procedures, along with their respective advantages and disadvantages, can be preferred as primary treatments for nutcracker syndrome. Our study demonstrates that both procedures can be safely and effectively performed, yielding good outcomes.

Reverse-U Aortotomy (Kirali Incision) for Aortic Valvular Interventions.

BACKGROUND: Surgical incisional approach to the ascending aorta is the main strategic step during valvular and/or subvalvular aortic interventions. Classic aortotomy incisions (transverse or oblique) can be challenging and can cause suboptimal exposure of the aortic root especially for the patients with small aortic annulus or for redo coronary artery bypass patients with patent proximal grafts interposed to the ascending aorta. METHODS: The Kirali incision was used in 91 patients (including 13 reoperations) who underwent an aortic intervention for valvular and subvalvular pathologies. Aortic root was exposed by forming inverted "U" shape incision starting from approximately 3 cm above the right coronary ostium toward the center of the noncoronary annulus and the top of the left-right commissure like a tongue. RESULTS: The aortic valve was replaced with a mechanical prosthesis in 45 patients and with a bioprosthesis in 39 patients including 14 sutureless and 16 stentless prostheses. A total of 29 patients received a concomitant procedure per the following: coronary artery bypass grafting on 8 patients and left ventricular assist device on 7 patients. There was no any problem related to aortotomy incision technique such as bleeding, rupture, dehiscence, or laceration perioperatively. There was no complication related to the procedure during 5-year follow-up. CONCLUSION: This new aortotomy incision technique is a safe procedure that provides good exposure for all kinds of aortic valve interventions and protects grafts and can facilitate aortic root enlargement or aortoplasty easily. This incision has the potential to be an alternative to traditional techniques.

Long-Term Results of Thoracofemoral Bypass in the Initial Treatment of Juxtarenal Total Aortic Occlusion.

BACKGROUND: Thoracofemoral bypass has been applied mostly secondary to previous procedures in the treatment of aortoiliac occlusive disease. However, its application as an initial treatment is less common, and long-term outcomes remain uncertain. The aim of this analysis was to review the 16-year experience and long-term outcomes of 31 consecutive patients who underwent thoracofemoral bypass as the primary procedure. METHODS: All patients who underwent thoracofemoral bypass for severe aortoiliac occlusive disease between 2005 and 2021 were retrospectively analyzed. The occlusion and calcified plaques of the abdominal aorta at the renal level were common characteristics of all patients. The patients were divided into 2 groups: severe claudication group (Rutherford III group) and chronic limb-threatening ischemia group (Rutherford IV-V). Chi-square test or Fisher's exact test was used to compare categorical variables between the groups, and t-test or Mann-Whitney U-tests were used to compare continuous variables according to their distributions. The Kaplan-Meier curve was used to depict the time-to-event data. RESULTS: Thirty-one patients [age: 62 (56-67.5); male: 87%] underwent thoracofemoral bypass. Among the 31 patients, 21 (67.7%) belonged to the severe claudication group (Rutherford III), while 10 (32.3%) were in the chronic limb-threatening ischemia (Rutherford IV-V). Twenty-two patients (83.8%) remained asymptomatic after thoracofemoral bypass. The mean follow-up duration was 79 ± 32 months. The 30-day mortality rate was 3.2% (n = 1). Major complications were observed in 9.6% of patients (n = 3; respiratory: 6.4%, retroperitoneal hematoma: 3.2%). No significant difference was found between the claudication and chronic limb-threatening ischemia groups regarding major complications (3.2% vs. 6.4%, P = NS). Minor complications occurred in 41.9% of patients, including pleural effusion 9.6% (n = 3), acute kidney injury 9.6% (n = 3), gastrointestinal bleeding 3.2% (n = 1), paralytic ileus 6.4% (n = 2), and superficial skin infection 12.9% (n = 4). The rate of postoperative superficial skin infection was higher in the chronic limb-threatening ischemia group compared to the claudication group (4 [40%] vs. 0 [0%], P: 0.007). The univariable Cox regression analysis revealed that hypertension and diabetes mellitus were not related to primary patency of the thoracofemoral bypass graft. The 5-year Kaplan-Meier estimated primary patency for the entire study was 96% ± 7% (95% confidence interval [CI]: 88.6-100), and the secondary patency was 96.3% ± 6% (95% CI: 89.4-100). The 5-year Kaplan-Meier estimated survival rate after thoracofemoral bypass was 93.4% ± 3 (95% CI: 91-100). CONCLUSIONS: We demonstrated in this study that thoracofemoral bypass can yield good outcomes when preferred as the initial treatment in selected patients with juxtarenal total aortic occlusion. Despite being a complex surgical technique, thoracofemoral bypass has shown to have safe, acceptable mortality and morbidity rates, as well as excellent long-term follow-up results in selected patients.

Transcatheter Closure or Surgery for Symptomatic Paravalvular Leaks: The Multicenter KISS Registry.

BACKGROUND: The optimal treatment of symptomatic paravalvular leak (PVL) remains controversial between transcatheter closure (TC) and surgery. This large-scale study aimed to retrospectively evaluate the long-term outcomes of the patients who underwent reoperation or TC of PVLs. METHODS AND RESULTS: A total of 335 (men, 209 [62.4%]; mean age, 58.15±12.77 years) patients who underwent treatment of PVL at 3 tertiary centers between January 2002 and December 2021 were included. Echocardiographic features, procedure details, and in-hospital or long-term outcomes were assessed. The primary end point was defined as the all-cause death during follow-up. The regression models were adjusted by applying the inverse probability weighted approach to reduce treatment selection bias. The initial management strategy was TC in 171 (51%) patients and surgery in 164 (49%) cases. Three hundred cases (89.6%) had mitral PVL, and 35 (10.4%) had aortic PVL. The mean left ventricular ejection fraction was 52.03±10.79%. Technical (78.9 versus 76.2%; P=0.549) and procedural success (73.7 versus 65.2%; P=0.093) were similar between both groups. In both univariate and multivariable logistic regression analysis, the in-hospital mortality rate in the overall population was significantly higher (15.9 versus 4.7%) in the surgery group compared with the TC group (unadjusted odds ratio, 3.13 [95% CI, 1.75-5.88]; P=0.001; and adjusted odds ratio (inverse probability-weighted), 4.55 [95% CI, 2.27-10.0]; P<0.001). However, the long-term mortality rate in the overall population did not differ between the surgery group and the TC group (unadjusted hazard ratio [HR], 0.86 [95% CI, 0.59-1.25]; P=0.435; and adjusted HR (inverse probability-weighted), 1.11 [95% CI, 0.67-1.81]; P=0.679). CONCLUSIONS: The current data suggest that percutaneous closure of PVL was associated with lower early and comparable long-term mortality rates compared with surgery.

Serum Levels of Cholesterol and Lipoproteins in Patients With Symptomatic Paravalvular Leaks.

Paravalvular leak (PVL) is a complication of valve replacement surgery which may lead to serious clinical consequences including hemolytic anemia. This study aimed to retrospectively evaluate the effect of successful intervention on serum lipid parameters in patients with PVL. A total of 106 patients (mean age: 57.2 ± 13.6 years, male: 67) who underwent surgical or transcatheter closure for symptomatic PVL were enrolled in this study. During the follow-up period, hemolysis and lipid parameters were evaluated at each clinical visit. This is the first study describing the effects of PVL on lipid metabolism after surgical or transcatheter closure. In the study, 18 patients (17%) had aortic PVL, 84 patients (79%) had mitral PVL, and 4 patients (3.8%) had both aortic and mitral PVL. A total of 59 patients underwent transcatheter closure and 47 patients were treated surgically. Technical success of the procedures was 83%. After successful PVL closure, hemoglobin and haptoglobin levels increased significantly (9.5 ± 1.3 vs 11.9 ± 2.1 g/dl, p <0.001 and 16.6 ± 7.9 vs 34.1 ± 19.9 mg, p <0.001, respectively). A significant increase in total cholesterol (158.9 ± 42.7 vs 209.3 ± 58.7 mg/dl, p <0.001), low-density lipoprotein cholesterol (99.1 ± 33.8 vs 133.9 ± 45.7 mg/dl, p <0.001), and high-density lipoprotein cholesterol (39.8 ± 12.4 vs 44.8 ± 11.7 mg/dl, p <0.001) levels was observed after successful PVL closure. In conclusion, symptomatic patients with PVL had hypocholesterolemia, reflected by low serum lipoprotein levels. After successful PVL closure, an increase in serum lipoprotein levels was observed. The recovery in levels of lipoproteins could be used as a marker of successful PVL closure, and absence of recovery of lipoprotein levels may indicate incomplete closure.

Thrombolysis or Surgery in Patients With Obstructive Mechanical Valve Thrombosis: The Multicenter HATTUSHA Study.

BACKGROUND: Prosthetic valve thrombosis (PVT) is one of the life-threatening complications of prosthetic heart valve replacement. Due to the lack of randomized controlled trials, the optimal treatment of PVT remains controversial between thrombolytic therapy (TT) and surgery. OBJECTIVES: This study aimed to prospectively evaluate the outcomes of TT and surgery as the first-line treatment strategy in patients with obstructive PVT. METHODS: A total of 158 obstructive PVT patients (women: 103 [65.2%]; median age 49 years [IQR: 39-60 years]) were enrolled in this multicenter observational prospective study. TT was performed using slow (6 hours) and/or ultraslow (25 hours) infusion of low-dose tissue plasminogen activator (t-PA) (25 mg) mostly in repeated sessions. The primary endpoint of the study was 3-month mortality following TT or surgery. RESULTS: The initial management strategy was TT in 83 (52.5%) patients and surgery in 75 (47.5%) cases. The success rate of TT was 90.4% with a median t-PA dose of 59 mg (IQR: 37.5-100 mg). The incidences of outcomes in surgery and TT groups were as follows: minor complications (29 [38.7%] and 7 [8.4%], respectively), major complications (31 [41.3%] and 5 [6%], respectively), and the 3-month mortality rate (14 [18.7%] and 2 [2.4%], respectively). CONCLUSIONS: Low-dose and slow/ultraslow infusion of t-PA were associated with low complications and mortality and high success rates and should be considered as a viable treatment in patients with obstructive PVT.

COVID-19 presenting with diarrhea in a heart transplant patient.

A 55-year-old man who underwent bicaval orthotopic heart transplantation nine months earlier presented with complaints of diarrhea and oliguria. Laboratory findings showed pancytopenia and an elevated creatinine level. Cyclosporine and mycophenolate mofetil were discontinued, and the patient received only everolimus. As he was immunosuppressed and had atypical symptoms during the COVID-19 pandemic, reverse transcriptase-polymerase chain reaction testing was performed, which yielded a positive result. Treatment with hydroxychloroquine and favipiravir were initiated. Although the patient suffered from acute renal failure, his condition showed an improvement after hydration plus a five-day antiviral treatment and, then, treatment was stopped. His COVID-19 test was negative after 10 days of follow-up and treatment, and he was discharged with cyclosporin and mycophenolate mofetil.

In-Hospital and Long-Term outcomes after Open-Heart Surgery in Turkish Octogenarians: a Single-Center Study.

OBJECTIVE: We aimed to analyze the early and long-term results of open-heart surgery in Turkish patients aged 80 years or older who were operated on at our center. METHODS: All patients aged 80 years or older who underwent surgery between January 2000 and December 2013 at a high-level heart center were included in the study. The in-hospital data of study patients were obtained from the electronic database and from the hospital files. Survival data were analyzed as a long-term outcome. RESULTS: A total of 245 patients aged 80-93 years were evaluated in the study. The patients were followed up 5.4±3.7 years after open-heart surgery. In-hospital mortality rates were 10% in elective cases and 15.1% overall. Age ≥85 years, chronic kidney disease, chronic obstructive pulmonary disease, and emergency surgery were independent predictors of in-hospital mortality. The median survival time was found to be 4.4±0.3 years for all participants. The long-term survival of patients who underwent emergency cardiac surgery was significantly lower than that of elective patients (log-rank <0.001). CONCLUSION: Octogenarians have satisfactory long-term outcomes after open-heart surgery when operated electively. On the other hand, patients operated under emergency conditions have worse inhospital outcomes and long-term follow-up results.

MitraClip Removal During Left Ventricular Assist Device Implantation.

Mitral regurgitation (MR) is an important consequence of heart failure (HF) patients, which increases hospitalization and mortality rates. The MitraClip procedure is increasingly preferred for HF patients with obvious MR to improve MR and related symptoms. In some cases, patients may need further intervention such as left ventricular assist device implantation with the aim of improving progressive clinical deterioration caused by the progression of HF or mitral clip associated complications (i.e., detachment or mitral stenosis). This case study summarizes our two patients who received concomitant mitral clip removal and left ventricular assist device implantation with clinically successful results.

Clinical Effects of Pleurotomy on Postoperative Outcomes of Patients Undergoing On-Pump Coronary Artery Bypass Grafting with Skeletonized Left Internal Thoracic Artery.

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.

Transition from Conventional Technique to Less Invasive Approach in Left Ventricular Assist Device Implantations.

Surgical treatments for heart failure patients are being increasingly performed every year. While experiences in this field are increasing, transition to alternative surgical approaches to minimize incisions is gaining popularity. However, there are clinics that still avoid performing these techniques. In the current study, we aim to present our experiences in transitioning to a minimally invasive technique by comparing two groups. One group was operated with a minimally invasive technique that has been performed in the learning curve period, while the second was operated with a familiar and standard technique. One hundred twenty patients who were implanted with left ventricular assist devices (LVADs) from April 2015 to January 2019 were retrospectively analyzed. The first 30 LVAD-implanted patients via less invasive approach (since April 2017) were included in group 1, and the last 30 isolated LVAD implanted patients via standard full sternotomy were included in group 2. Early clinical outcomes were compared between these two groups. There were no significant differences between two groups in terms of demographic features and preoperative statuses. Group 1 had significantly lesser mortality rates, cardiopulmonary bypass times, drainages, and blood products. Hospital stays had no significant difference between the groups, while extubation times and ICU stays were significantly lesser in group 1. Left ventricular assist device implantation through thoracotomy and ministernotomy is as feasible as that done through the conventional full sternotomy technique. In this group of patients with a high risk of bleeding, besides providing less hemorrhage, we believe that the surgical procedure was not more difficult than the conventional method.

The publication rate of oral presentations presented in national congresses of Turkish Society of Cardiovascular Surgery.

BACKGROUND: This study aims to investigate the literature contribution of oral presentations presented in the largest national congresses of the Turkish Society of Cardiovascular Surgery. METHODS: A total of 675 orally presented abstracts during biannually organized 12th, 13th, and 14th congresses were reviewed using the PubMed and Google Scholar databases in May 2018. Abstracts were searched for institutions where they were submitted, publication status in scientific journals, type of peer-reviewed journal, and publication year. RESULTS: Of a total of 675 oral presentations, 69.1% were clinical studies, 18.8% were case reports, and 12.1% were experimental researches. Of all accepted abstracts, 47.3% were from university hospitals, 36.1% were from training and research hospitals, and 16.6% were from other multi-center institutions. A total of 279 (41.3%) abstracts were published in a scientific journal. There was a significant difference among the institutions in terms of the rate of publication (p=0.04), and the university hospitals had the highest rate. The mean time from presentation to publication in a scientific journal was 16.7±9.1 (range, 4 to 60) months. CONCLUSION: The rate of published abstracts from the last three congresses of the Turkish Society of Cardiovascular Surgery is higher compared to the literature results reporting national congresses of other specialties, but is lower than the international congresses. We believe that this ratio should be increased to reach the same level as international reports and the methods to encourage researchers to publish should be developed.

Intra-aortic balloon pump experience: a single center study comparing with and without sheath insertion.

Introduction: The mechanical circulation support used in treatment of low cardiac output at most is the intra-aortic balloon pump (IABP). Its usage fields are the complications occurring due to ischemic heart disease, disrupted left ventricle function, and the low cardiac output syndrome occurring during coronary artery by-pass surgery. Methods: During 28 years from 1985 to 2013, IABP support has been implemented to 3135 patients in our cardiac surgery operating theater and intensive care unit. The mean age of the patients was 61.4 ± 13.2 years (16-82). 2506 patients (80%) were the ones whom the cardiac surgery has been implemented. IABP support has been provided for 629 (20%) patients for medical treatment. We utilized IABP most frequently in coronary artery patients (70%). The first choice for placing the balloon catheter is the femoral artery in 3093 cases (98.7%). Results: The most frequently observed balloon complication was the lower extremity ischemia in 383 cases (12.2%).The leg ischemia was statistically significantly more frequent in patients with sheath (P=0.004). The extremity ischemia has developed in 4 of 12 patients with balloon placed from upper extremity. The local bleeding and balloon rupture were more frequent in patients whom the balloon has been placed without sheath. The mortality due to IABP has occurred in only 5 patients. Conclusion: Despite increase in IABP usage frequency rapidly, the complications due to catheter are still seen. We believe that the leg ischemia that is the most frequently seen complication can be prevented via IABP use without sheath.

Outcomes After Surgical Resection of Primary Non-Myxoma Cardiac Tumors.

OBJECTIVE: Primary cardiac tumors are rare lesions with different histological type. We reviewed our 17 years of experience in the surgical treatment and clinical results of primary non-myxoma cardiac tumors. METHODS: Between July 2000 and February 2017, 21 patients with primary cardiac tumor were surgically treated in our institution. The tumors were categorized as benign non-myxomas and malignants. Data including the demographic characteristics, details of the tumor histology and grading, cardiac medical and surgical history, surgical procedure of the patients were obtained from the hospital database. RESULTS: Eleven patients were diagnosed with benign non-myxoma tumor (male/female:7/4), ranging in age from 10 days to 74 years (mean age 30.9±26.5 years). Papillary fibroelastoma was the most frequent type (63.6%). There were two early deaths in benign group (all were rhabdomyoma), and mortality rate was 18%. The mean follow-up period was 69.3±58.7 months (range, 3 to 178 months). All survivals in benign group were free of tumor-related symptoms and tumor relapses. Ten patients were diagnosed with malignant tumor (sarcoma/lymphoma:8/2, male/female:3/7), ranging in age from 14 years to 73 years (mean age 44.7±18.9 years). Total resection could be done in only three (30%) patients. The mean follow-up period was 18.7±24.8 months (range, 0-78 months). Six patients died in the first 10 months. CONCLUSION: Complete resection of the cardiac tumors, whenever possible, is the main goal of surgery. Surgical resection of benign cardiac tumors is safe, usually curative and provides excellent long-term prognosis. On the contrary, malignant cardiac tumors still remain highly lethal.

Total resection could be done in only three (30%) patients. The mean follow-up period was 18.7±24.8 months (range, 0-78 months). Six patients died in the first 10 months. Conclusion: Complete resection of the cardiac tumors, whenever possible, is the main goal of surgery. Surgical resection of benign cardiac tumors is safe, usually curative and provides excellent long-term prognosis. On the contrary, malignant cardiac tumors still remain highly lethal.

Cephalic vein thrombosis.

An 83-year-old male patient presented to the outpatient clinic with complaint of swelling at right antecubital area. Ultrasonographic examination of the right upper extremity revealed a mass lesion within the right cephalic vein, which was consistent with thrombus. A computed tomography (CT) venography showed contrast enhancement in cephalic vein at distal arm and an aneurysmatic thrombus area displaying regular borders with a size of 28*30 mm; there was no contrast enhancement at more proximal levels at the cephalic vein.
