Traumatic fracture of central venous catheter.

Central venous catheter (CVC) placement is frequently essential for the management of critically ill patients. This report describes a case involving the surgical retrieval of an embolized fragment of a CVC, originally intended for dialysis, following an unsuccessful removal attempt by a nurse due to catheter malfunction. The decision to remove and replace the malfunctioning catheter was made by the patient's physician. However, during the removal process, both the retaining suture and the catheter were inadvertently severed. This report also discusses the complications and management strategies associated with the embolization of a central line.

Clinical symptoms, pathogenesis and postoperative course of non-specific constrictive pericarditis with dumbbell-shaped heart.

Non-specific chronic constrictive pericarditis is a rare and debilitating chronic infection in developed countries and its rapid diagnosis and treatment has not affected its outcome and complication. A 15-year-old male, well nourished, negative HIV test, and without a history of previous pulmonary tuberculosis, was admitted to our hospital for exertional dyspnea (New York Heart Association, NYHA, functional class II). Our patient had had no pulmonary tuberculosis during childhood, had received anti-tuberculosis treatment, and was referred to our center for further surgical pericardiectomy.

Sex-Based Differences in One-Year Outcomes After Mitral Valve Repair for Infective Endocarditis.

INTRODUCTION: This study was aimed to evaluate the sex-based differences in baseline characteristics and one-year outcomes of men and women undergoing mitral valve repair for infective endocarditis. METHODS: This cross-sectional study was performed at Imam Ali Hospital affiliated with the Kermanshah University of Medical Science. From March 21, 2014, to October 21, 2021, all patients who underwent mitral valve repair for infective endocarditis were enrolled in this study. Data were obtained using a checklist developed based on the study's objectives. Independent samples t-tests, paired samples t-tests, and chi-squared test (or Fisher's exact test) were used to assess the differences between subgroups. RESULTS: Of 75 patients, 26 were women (34.7%) and 49 were men (65.3%). Women were more likely to have diabetes mellitus (20.4% vs. 57.7%, P=0.0001), hypertension (49% vs. 80.8%, P=0.007), and hypercholesterolemia (55.1% vs. 80.8%, P=0.027). Conversely, men were more likely to have a history of smoking (38.8% vs. 7.7%, P=0.004). After one year, women had significantly higher mortality (0% vs. 7.7%, P=0.049), major adverse cardiac and cerebrovascular events (51.0 vs. 76.9, P=0.029), mitral valve reoperation (8.1% vs. 34.6%, P=0.003), and treatment failure (30.6% vs. 61.5%, P=0.009) rates than men. CONCLUSION: Mortality, major adverse cardiac and cerebrovascular events, mitral valve reoperation, and treatment failure rates were higher in women than in men. The worse outcomes in women may be explained by their more adverse clinical risk profile.

Combined chest wall and liver hydatid cyst.

BACKGROUND: Hydatid cysts (HC) are primarily found in the liver, with secondary occurrences in the lungs and other organs. The presence of HCs in the anterior chest wall is notably rare, and even more so when associated with HCs in the liver. CASE PRESENTATION: A 53-year-old male reported to our facility with a non-painful lump on his chest's front wall. A thoraco-abdominal CT scan identified cysts within the chest wall's subcutaneous layer, showing no spread to nearby soft tissues or involvement of the lungs and ribs. Despite an echinococcal test returning negative, the initial diagnosis leaned towards a dermoid cyst. After surgical removal and detailed examination, the cysts were confirmed as HCs. Further investigation revealed an additional liver HC. The patient was referred for surgery where he underwent laparotomy and drainage of cyst content. CONCLUSION: This case underscores the importance of considering HCs when diagnosing palpable lesions on the chest wall, particularly in regions where HCs are endemic.

Cor triatriatum sinister with left superior vena cava, unroofed coronary syndrome and valvular pulmonary stenosis / Cor triatriatum sinistrum con vena cava superior izquierda, síndrome coronario destechado y estenosis de la válvula pulmonar

Abstract A 25-year-old woman with a history of recent dyspnea and palpitation was admitted to our center. Transthoracic echocardiography (TTE) showed an echogenic and septal muscular ridge along the left atrium which were indicative of cor triatriatum sinister (CTS). Further evaluation with transesophageal echocardiography (TEE) showed that a lower chamber of divided left atrium receiving lower right inferior pulmonary vein, mitral valve, left superior vena cava (LSVC) and unroofed coronary sinus (CS). Also, the lower chamber had an unrestrictive communication with the right atrium. The upper accessory chamber receiving one left and one right upper pulmonary vein and communicated with the right atrium by a small atrial septal defect (ASD). However, upper and lower pulmonary venous systems separated directly from each other by a muscular ridge without the presence of any window or hole to allows blood flow between these two accessory chambers. Although the absence of septum associated with the presence of LSVC and unroofed CS makes our case a unique or very rare type of this complex anomaly in an adult case. In our case, surgical removal of dividing muscular membrane with redirection of LSVC and unroofed CS to the right atrium are warranted.

Resumen Se trata de una paciente de sexo femenino, de 25 años de edad, con antecedentes recientes de disnea y palpitaciones que ingresó a nuestro centro. Un ecocardiograma transtorácico (ETT) evidenció un reborde ecogénico muscular del tabique de la aurícula izquierda indicativo de cor triatriatum sinistrum (CTS). En un estudio más a fondo con ecocardiografía transesofágica (ETE) se evidenció que una cámara inferior de la aurícula izquierda dividida recibía la vena pulmonar inferior derecha, la válvula mitral, la vena cava superior izquierda (VCSI) y el seno coronario (SC) destechado. Además, la cámara inferior tenía comunicación libre con la aurícula derecha. La cámara superior secundaria recibía una vena pulmonar superior izquierda y una derecha y se comunicaba con la aurícula derecha a través de una comunicación interauricular (CIA) pequeña. Sin embargo, los sistemas venosos pulmonares superiores e inferiores se encontraban separados entre sí por un reborde muscular sin la presencia de alguna ventana u orificio que permitiera el flujo de sangre entre estas dos cámaras secundarias. La ausencia del tabique junto con la presencia de la VCSI y el SC destechado hacen que nuestro caso sea un tipo único o extremadamente inusual de esta anomalía compleja en un caso en un adulto. En este caso, se justifica la extirpación quirúrgica de la membrana muscular divisoria con redireccionamiento de la VCSI y el SC destechado a la aurícula derecha.

A rare case of Watson syndrome.

Watson for the first time reported a case series of children in a family that presented with pulmonary valve stenosis, mental retardation, short stature, and small brown color skin lesions that are known as cafe-au-lait spots. We present a rare new variant of the syndrome in an adult patient with severe pulmonary valve stenosis, main, left, and right pulmonary artery aneurysm, short stature, mental retardation, coronary artery disease, and skin lesions. The patient underwent open cardiac surgery with pulmonary valvotomy and aneurysmorrhaphy of the main pulmonary artery and its right and left branches. The postoperative course was uneventful and the six-month follow-up with transthoracic echocardiography revealed no recurrence of aneurysm of repairing pulmonary arteries and good clinical outcome of the patient. Our patient had a unique characteristic of aneurysm of the main pulmonary artery and its both branches that has rarely been reported previously in the medical literature.

Combination of cardiac and carotid glomus tumour: a rare case report.

The most common tumour of the heart is myxoma but paraganglioma (also called glomus tumour in extracardiac sites) in the cardiac position is the rarest of them. While this tumour accounts for 0.8% of all primary benign tumours, the combination of both neoplasms is an exceedingly rare occurrence. Herein, we present a case of combined carotid glomus tumour and left atrial paraganglioma tumour in which respiratory distress was the presenting symptom of cardiac type but carotid tumour was asymptomatic. The case underwent a two-step resection of the neck and cardiac mass with an uncomplicated postoperative course and in the 1year follow-up, no recurrence of tumour in both sites was found on physical exam and imaging studies.

The Association of Dietary Total Antioxidant Capacity with Inflammatory Biomarkers and Anthropometric Indices in Patients Who Candidate for Coronary Artery Bypass Graft Surgery: a Cross-sectional Study.

Antioxidant compounds can attenuate inflammation and delay degenerative processes especially in the cardiovascular system. This study aimed to determine the relationship between dietary total antioxidant capacity (DTAC) and serum biomarkers in patients undergoing coronary artery bypass graft surgery. In this cross-sectional study, 146 patients who had referred to Imam Ali Hospital in Kermanshah were recruited and demographic, anthropometric, physical activity and dietary data were collected. Fasting blood glucose (FBG), serum levels of lipid profile, inflammatory markers (interleukin [IL]-17, intercellular and vascular cell adhesion molecules [ICAM, VCAM]), and total antioxidant capacity (TAC) were also measured. A regression model adjusted for confounding variables presented that the coefficients of ICAM and VCAM (ng/dL) in the third tertile of DTAC were lower than those in the first tertile (ß = -417.2, 95% confidence interval [CI] = -509.9 to -324.5, p < 0.001; ß = -293.2, 95% CI = -334.3, -252.1, p < 0.001, respectively). The ß of serum TAC (ng/dL) in the third tertile was 0.86 (95% CI = 0.77, 0.95, p < 0.001) higher than that in the first tertile. DTAC had no statistically significant relationship with lipid profile, FBG, and IL-17 levels, and anthropometric indices. In this study DTAC was associated with increased serum TAC and decreased cell adhesion molecules. Therefore, diet antioxidants may be beneficial in attenuating of inflammation in coronary artery diseases.

Cardiocutaneous fistula secondary to left ventricular pseudo-aneurysm rupture.

Cardiocutaneous fistula (CF) is a potentially serious and catastrophic complication. Infection the suture line after left ventricular aneurysm repair, presenting with the CF. We present an unusual case of CF due to staphylococcus infection 6 months after repair of a myocardial rupture secondary to dehiscence repair.

A Rare Location of Pseudoaneurysm in Subaortic Ring after Bentall Operation.

Bentall operation is considered a gold standard of surgery in the treatment of ascending aortic aneurysm. This operation with en-bloc resection of ascending aorta and aortic valve requires aortic valve with two coronary bottoms re-replacements in a prepared composite graft. The four important locations for the pseudoaneurysm include proximal and distal composite graft anastomosis and two coronary bottom sites. However, many complications have been reported with this technique but the most serious complication associated with this operation is defined as pseudoaneurysm. We report an exceedingly rare case of subaortic ring pseudoaneurysm in retro composite graft position enclosed by infected surgical that was used to control bleeding in this location. Dehiscence occurred between the aortic ring and the underlying left ventricular muscle. The aortic ring was separated from the underlying muscle by the high tensile strength of sewing ring sutures. The pseudoaneurysm compressing the left atrium without communicating with any cardiac chamber and presenting with high fever (39°C), chills, a few months after Bentall operation. The patient underwent redo operation and repair of the dehiscence's site. The 6-month follow-up revealed no recurrence of a pseudoaneurysm. The uniqueness of this case report is related to the site of pseudoaneurysm between the aortic ring and underlying left ventricular muscle that have not been reported in the medical literature so far.

Association of cardiac enzymes with morbidity and mortality of patients undergoing coronary endarterectomy surgery.

BACKGROUND: The relationship between cardiac enzyme release following coronary endarterectomy (CE) and morbidity and mortality is unclear. Therefore, the present study aimed to investigate the association of cardiac enzymes with morbidity and mortality of patients undergoing CE surgery. METHODS: This was a single-center retrospective cohort study of 475 patients who had undergone off-pump coronary artery bypass graft (OPCABG). The patients were followed up for a mean of 72.99 ± 14.60 months. RESULTS: Among 475 patients undergoing OPCABG, 39 (8.2%) were non-survivors. Non-survivors were younger and had a fewer ejection fraction (EF). Comorbidities were similar in survivors and non-survivors. The crude Cox regression analysis showed that creatine kinase-myocardial band (CK-MB) had a protective effect against mortality, but when adjusted with age, sex, diabetes mellitus (DM), hypertension (HTN), hyperlipidemia, smoking, family history, body mass index (BMI), left main disease (LMD), and EF, this effect disappeared. Troponin in crude and adjusted analysis did not have any significant effect. CONCLUSION: There is no association between CK-MB and troponin and mortality in patients undergoing coronary artery bypass graft (CABG).

Gender difference in long- and short-term outcomes of off-pump coronary endarterectomy.

Background: The role of gender in the selection of the most effective method for treatment of patients with diffused coronary artery diseases remains a matter of debate. This study thus evaluated the effect of gender on long- and short-term outcomes of off-pump coronary endarterectomy (CE). Methods: This was a single-center retrospective study of patients who had undergone coronary artery bypass graft (CABG). The patients were divided into two groups, the CABG and the CABG + CE group, and further stratified into male and female. Long-term survival for each group was estimated by Kaplan-Meier analysis with log-rank testing. In addition, Cox regression analyses of each gender were also carried out to identify the predictors of the primary and secondary endpoints. Results: Overall, 25.8% of the patients were female. Diseased vessels were not statistically different in the two groups - men and women. There was no significant difference in postoperative outcomes between males and females in the CABG and CABG + CE groups. There was no significant difference in hospital mortality in the two groups between males and females. Kaplan-Meier curves show that there was no significant difference in the 5-year cardiac mortality between males and females belonging to the CABG and CABG + CE groups. Conclusion: The results of this study show that there was no significant difference in the short- and long-term outcomes of off-pump CABG and CE in both genders although women tend to carry a greater risk.

Anabolic Steroid Use and Aortic Dissection in Athletes: A Case Series.

The use of anabolic steroids in supraphysiologic doses has grown in the last decade as doping drugs in athletes. The high dose of anabolic-androgenic steroids (AAS) causes cardiomyopathy, hypertension, thrombosis, myocardial infarction (MI), weakness of connective tissue, and its sequelae such as tendon injury and aortic dissection. Dissection of the ascending aorta is an uncommon injury that has been recognized with increasing frequency in bodybuilders in recent years. It has been proposed that such cases commonly accompany the weakening of connective tissue and must be actively evaluated in the presence of anabolic steroid usage. We present a case series of isolated ascending aorta dissection in athletes who were bodybuilders. All cases were evaluated by transthoracic echocardiography (TTE) and laboratory exams. These cases also served as a reminder of the risks of ascending aorta dissection with AAS, especially in strength athletes who place high demands on their musculoskeletal structures. The results of the current study suggested that anabolic steroid abuse may be associated with detrimental effects on the myocardium represented as cardiomyopathy or atherosclerotic changes in the coronary artery as MI. These findings also strongly suggest that anabolic steroid treatment predisposes the individual to aortic dissection, especially when the patients are exercised.

Traumatic Hemolytic Anemia after Valve Surgery: a Case Report.

Hemolytic anemia is an uncommon complication after mitral valve repair. We present a case of a 55-year-old man who presented with post-operative hemolytic anemia after mitral valve repair with prosthetic ring. The hemolytic anemia improved after the patient had the prosthetic ring removed and the valve replaced by a prosthetic mitral valve. However, the post-operative course of the redo operation was complicated by acute renal failure and respiratory dysfunction, but the hemolytic anemia was finally abolished and the patient was discharged 20 days post-operatively in good condition.

Right Atrial Blood Cyst with Stones Suspended from the Coronary Sinus.

Cardiac blood cysts are rare benign neoplasms, usually involving the cardiac valves and are remnants of the Chiari network. They are usually detected in the first six months of life and rarely occur in children or adults. We report a 76-year-old male patient who was referred to the Imam Ali Hospital affiliated with Kermanshah University of Medical Sciences, Kermanshah, Iran, in 2018 with dyspnoea. Transthoracic echocardiography revealed a small patent foramen ovale (PFO) and a circumferential mobile cystic mass in the right atrium, with the impression of a tumour or thrombus. The patient underwent open-heart surgery with cardiopulmonary bypass to repair to PFO and remove the intra-atrial lesion. During surgical examination of the right atrial cavity, a blood cyst containing small stone-like structures on the coronary sinus valve of the right atrium was found. The post-operative course was uneventful and no recurrence of tumour was detected during six months of follow-up. To the best of our knowledge, this is the first reported case of a right atrial blood cyst with a few nodule-like stones in an adult with PFO in Iran and the second case in an adult with PFO worldwide.

Combined association of liver and renal injury by intra-aortic balloon pump malposition.

BACKGROUND: We report an unusual visceral complication of intra-aortic balloon pump (IABP) due to the malpositioning of the catheter in the aorta. CASE REPORT: A 55-year-old man with severe left ventricular dysfunction underwent coronary artery bypass grafting (CABG) with the preoperative use of an intra-aortic balloon pump. Postoperative course was complicated by renal and hepatic failure. The early occurrence of complications during 36 hours after operation exhibited a serious vascular complication. The combination of acute renal and hepatic failure led to the suspension to occlusive effect of intra-aortic balloon pump catheter on ostium of the aforementioned organs. The intra-aortic balloon pump was removed, and urine output immediately restored. Thereafter, daily slop dawn serum levels of aminotransferases were started, and became normal at the 10th day of operation. CONCLUSION: This is an exceptional case that shows how intra-aortic balloon pump may be contributed to mechanical aortic side branches obstruction. A high index of suspension is mandatory in the diagnosis of such bizarre complications.

Congenital combined atresia of the left main coronary with supravalvar aortic stenosis.

Congenital atresia of the left main coronary artery (LMCA) is an exceedingly rare phenomenon, and in the most of them, coronary artery bypass graft is required. We here describe a rare case of this anomaly that concomitantly was associated with supravalvar aortic stenosis and coronary-pulmonary fistula without the presence of conventional collateral circulation in a 16-year-old boy. The patient was admitted to our center with chest pain and dyspnea. Echocardiographic examinations showed supravalvar aortic stenosis with normal function of the aortic valve. Coronary angiography revealed atresia of LMCA with poorly developed left anterior descending coronary artery and well-developed circumflex coronary artery and diagonal artery that perfused by dominant and lengthy right coronary artery. The patient underwent coronary artery bypass grafting with repair of supravalvar aortic stenosis. The postoperative course was uneventful. The 6-month follow-up revealed normal diameter of the ascending aorta with symptomatic relief of preoperative chest complaint.

Minimal Invasive Technique in Atrial Septal Defect Surgery.

BACKGROUND: Median sternotomy with minimal skin incision (MSWMSI) and modified anterior mini-thoracotomy (MAMT) approach that both are innovative techniques modified from previous documented techniques are important alternative to conventional median sternotomy in atrial septal defect (ASD) repair. Our aim is to explain the details of two performed techniques in our center and explain the results. METHODS: Totally 54 children with ASD (20 female and 34 male) were operated with two different techniques i.e. MAMT and MSWMSI in Imam Ali heart surgery center between May 2010 and May 2013. Intra and postoperative variables such as cardiopulmonary bypass time and aortic cross-clamp time, intensive care unit stay time, length of incision, postoperative hematoma and seroma, dehiscence mortality, exploration for postoperative bleeding, neurologic complication, infection and amount of blood transfusion were recorded. RESULTS: Mean cardiopulmonary bypass time was 30 ± 11 min, and mean aortic cross-clamp time was 7 ± 2 min. The mean amount of blood transfusion was 150 ± 39 mL, and the mean chest tube drainage after surgery was 140 ± 57 mL. Superficial skin infection occurred in three patients. Subcutaneous hematoma and seroma were founded in six patients. In 50 cases the defect was secundum type, in two patients it was sinus venosus type, and in two with associated perimembranous ventricular septal defect repair. CONCLUSION: Both approaches are safe and may be the surgical techniques of choice for secundum ASD repair in all age groups; and we can also utilize these techniques for more complicated kinds of surgery, for instance, sinus venosus type ASD with or without partial anomalous defect.

A Road to the Heart From Uterine Closet: A Case Report.

Angiosarcomas of the uterine is a malignant and poor prognostic tumor and can either be a primary sarcoma or arising secondary to radiotherapy of a more complex tumor. Primary uterine angiosarcomas are exceptional and probably arise from embryonic vascular remnants, teratoma or from the rich uterine vasculature. We reported a rare case of primary angiosarcoma of uterine that at the time of diagnosis presented with sign and symptom of local and distant metastasis. The patient presented with dyspnea, chest pain, and history of vaginal bleeding and pelvic pain. The physical exam revealed pallor, prominent jugular pulse pressure, a palpable fixed mass in the pelvic however vaginal exam was unremarkable. Transthoracic echocardiography (TTE) revealed massive pericardial effusion and also a large mass in the right atrium. The abdominal ultrasound showed echogenic and poor echogenic segments in uterine mass combined with central necrosis. The patient underwent total hysterectomy and Bilateral salpingo-oophorectomy followed by radiotherapy and adjuvant chemotherapy. The patient underwent open heart surgery with resection of cardiac mass and further received a four cycle of radiotherapy (50 MG) to the mediastinum. The further follow-up (6 month) revealed no recurrence of tumor in a mediastinum. However, patient died from metastasis to the liver and its hepatic failure sequels.
