Abstract
In pediatric patients with hemolytic uremic syndrome (HUS), cardiac involvement and autonomic nervous system function can be evaluated by a non-invasive method called heart rate variability (HRV). This study aims to evaluate heart rate variability and electrocardiography findings in patients with HUS by comparing a healthy group. Patients who are diagnosed with HUS at a university hospital from December 2020 to June 2022 are screened by electrocardiography (ECG), echocardiography, and 24-h Holter ECG. A healthy control group, compatible in age and gender with the patient group, was selected from healthy subjects. HRV parameters, laboratory values, and ECG findings were analyzed and compared with the healthy group and each other. There were 25 patients with HUS and 51 participants in the healthy control group. Statistically significant differences were found in some HRV parameters: standard deviation of normal to normal intervals, the mean of the 5-min RR interval standard deviations, the standard deviation of 5-min RR interval means, the triangular interpolation of normal to normal interval, and very-low-frequency power. HUS patients had impaired and declined HRV values compared to the healthy group. There was a significant decrease in the PR distance, while a significant increase in the corrected QT and QT dispersion values was detected in the electrocardiographic findings of the patient group. HRV values impaired as renal failure parameters increased. Conclusion: Patients with HUS may have autonomic nervous system dysfunction. HRV measurement is a non-invasive method that can evaluate this. It can be thought that there may be an increased risk of cardiovascular events and arrhythmias in some patients with HUS. ECG should be also considered to detect arrhythmia. What is Known: • Hemolytic uremic syndrome (HUS) primarily effects the hematologic parameters and kidney. • Secondary cardiomyopathy with hypertension and renal failure could be observed in these patients. • Rhythm problems are not expected primarily in these patients. • There is very limited data in evaluating autonomic function and arrhythmia risk for these patients. What is New: • Patients with HUS may have autonomic nervous system dysfunction. • HRV measurement is a non-invasive method that can evaluate this. • Cardiovascular events and arrhythmias due to the deterioration of the balance between the sympathetic and parasympathetic systems could manifest in patients with HUS. • An ECG and screening patients for cardiac events, and monitoring them closely should be considered.

Abstract
INTRODUCTION AND AIM In pediatric multisystem inflammatory syndrome and isolated viral myocarditis/myopericarditis, autonomic nervous system function can be evaluated by a non-invasive method called heart rate variability. This study aims to evaluate heart rate variability in these two groups by comparing them with each other. This is the first study assessing these values in these two groups of patients. METHOD Patients who are diagnosed with multisystem inflammatory syndrome in children and isolated viral myocarditis/myopericarditis at a university hospital from September 2021 to February 2023 are screened by electrocardiography, echocardiography, and 24-hour Holter monitoring. A healthy control group, compatible in age and gender with the patient groups, was selected from healthy subjects that applied to the hospital for palpitation, murmur, and/or chest pain. Heart rate variability parameters and related laboratory markers were analyzed and compared among the three groups. RESULTS There were 30 patients with multisystem inflammatory syndrome in children, 43 patients with isolated viral myocarditis/myopericarditis, and 109 participants in the healthy control group. Statistically significant differences were found in most of the heart rate variability parameters: standard deviation of normal to normal intervals (SDNN), the mean of the 5- minute RR interval standard deviations (SDNNİ), the standard deviation of 5-minute R wave to R wave(RR) interval means (SDANN), the root mean square of successive RR interval differences (RMSSD), and the percentage of the beats with a consecutive RR interval difference of more than 50 ms (pNN50%), very low frequency, high frequency, low frequency, triangular index, and low frequency/high-frequency ratio. Multisystem inflammatory syndrome in children patients had impaired and declined heart rate variability values compared to the other two groups. In patients with myocarditis/myopericarditis, we couldn't find a significant difference in these parameters with the control group. CONCLUSION Heart rate variability can be used as an important non-invasive autonomic function parameter in determining prognosis and treatment plans, especially in patients diagnosed with multisystem inflammatory syndrome in children. This impairment of autonomic activity could be more prominent in patients with decreased left ventricular systolic functions.

Abstract
Multisystem inflammatory syndrome (MIS-C) in children is a rare complication of SARS-CoV-2 infection. Knowing the course of the affected or unaffected coronary arteries in the patients under follow-up is important in terms of defining the long-term prognosis of the disease and determining the follow-up plan. This is a multicenter and retrospective study. The data were obtained from nine different centers. Between May 2020 and August 2022, 68 of 790 patients had coronary artery involvement. One-year echocardiographic data of 67 of 789 MIS-C patients with coronary artery involvement were analyzed. Existing pathologies of the coronary arteries were grouped as increased echogenicity, dilatation and aneurysm according to Z scores, and their changes over a 1-year period were determined. The data of all three groups are defined as frequency. SPSS Statistics version 22 was used to evaluate the data. In our study, aneurysm was observed in 16.4%, dilatation in 68.7% and increased echogenicity in 13.4% of the patients. All of the patients with involvement in the form of increased echogenicity recovered without sequelae by the end of the first month. No progression to aneurysm was observed in any of the patients with dilatation. No new-onset involvement was observed in patients with previously healthy coronary arteries during the convalescent period. In addition, from the sixth month follow-up period, there was no worsening in the amount of dilatation in any of the patients. At least 94% of the patients who completed the 12th month control period returned to normal.

Abstract
OBJECTIVE This study aimed to analyse the influence of improved antenatal detection on the course, contemporary outcomes, and mortality risk factors of the complete atrioventricular block during fetal-neonatal and childhood periods in South Wales. METHODS The clinical characteristics and outcomes of complete atrioventricular block in patients without structural heart disease at the University Hospital of Wales from January 1966 to April 2021 were studied. Patients were divided into two groups according to their age at diagnosis: I-fetal-neonatal and II-childhood. Contemporary outcomes during the post-2001 era were compared with historical data preceding fetal service development and hence earlier detection. RESULTS There were 64 patients: 26 were identified in the fetal-neonatal period and the remaining 38 in the childhood period. Maternal antibodies/systemic lupus erythematosus disease (anti-Ro/Sjögren's-syndrome-related Antigen A and/or anti-La/Sjögren's-syndrome-related Antigen B) were present in 15 (57.7%) of the fetal-neonatal. Fetal/neonatal and early diagnosis increased after 2001 with an incidence of 1:25000 pregnancies. Pacemaker implantation was required in 34 patients, of whom 13 were diagnosed in the fetal-neonatal group. Survival rates in cases identified before 2001 were at 96.3% (26/27), whereas it was 83.8% (31/37) in patients diagnosed after 2001 (P > 0.05). Other mortality risk factors comprised a lower gestational week at birth, maternal antibodies, and an average ventricular heart rate of < 55 bpm. CONCLUSIONS Fetal diagnosis of complete atrioventricular block is still portends high fetal and neonatal mortality and morbidity despite significantly improved antenatal detection after 2001. Pacemaker intervention is needed earlier in the fetal-neonatal group. Whether routine antenatal medical treatment might alter this outcome calls for further prospective multicentre studies.

Abstract
BACKGROUND The objective of our study was to determine the role of retinoic acid receptor gamma (RARG) rs2229774, SLC28A3 rs7853758, and UGT1A6*4 rs17863783 single-nucleotide polymorphisms in identifying the risk of doxorubicin-induced cardiotoxicity in pediatric solid tumors. METHODS A total of 60 pediatric patients who had completed their treatment at least 2 years ago and 50 healthy children matched for age and sex were included in the study. All patients were evaluated for cardiotoxicity by echocardiography. The blood samples were analyzed for RARG rs2229774, SLC28A3 rs7853758, and UGT1A6*4 rs17863783 polymorphisms. Demographic characteristics, echocardiographic parameters, and genetic results of both groups were evaluated. RESULTS In our study, the RARG rs2229774 AA genotype was associated with cardiotoxicity ( P =0.017). The SLC28A3 rs7853758 AA+GA genotype was detected more frequently in patients who did not develop cardiotoxicity ( P <0.023). Furthermore, the frequency of the SLC28A3 rs7853758 A allele was significantly lower in the cardiotoxicity group ( P <0.025). CONCLUSIONS This is the first study in the Turkish population to investigate the correlation between the cardiotoxicity risk and 3 marker genes, which are recommended in the pharmacogenetic guideline for risk assessment in pediatric doxorubicin patients. The gene polymorphism that we investigated in this study was useful for the early prediction of cardiotoxicity risk.

Abstract
AIM In this study, it is aimed to analyze the data of children who were referred to our clinic for pre-participation sports screening. METHODS Data, between September 2017 and December 2021, had been analyzed. All these subjects had been questioned for their personal and family medical stories and examined for cardiovascular system findings. Electrocardiography (ECG) and echocardiography were applied to all of them. RESULTS 11487 children were consulted to the cardiology clinic for pre-sports participation screening. The mean age was 12.7±4,57 (7-18 years). 34/11487(0,29%) subjects weren't allowed to participate in sports activities at first. In 23 of 34 subjects, cardiac arrhythmias were established. 15 had Wolff-Parkinson-White (WPW) syndrome, 3 subjects had ventricular extrasystole, and also ventricular tachycardia in one of them. Four subjects had long QT syndrome and one had ST elevation with the pre-diagnosis of coronary artery disease. ECG screening alone aided in identifying asymptomatic (0.05%) that could have been potentially at risk for sudden cardiac death. CONCLUSION Positive ECG and echocardiography findings involve a very little ratio.But ECG involves an important tool for screening lethal cardiac arrhythmias in asymptomatic patients.If ECG or echocardiography couldn't be taken, further evaluation should be necessary with symptoms and/or family history.

Abstract
BACKGROUND Split/fracture and embolization of central venous/shunt catheters are rare but serious complications in children. Percutaneous retrieval of intravascular foreign bodies is an important minimal invasive treatment. This study is aimed to represent our largest pediatric sample experience till now of 17 years from a single institution. Another aim is to compare the results regarding the removal or leaving in place of embolized or ruptured intravascular or cardiac venous catheter parts in children. PATIENTS AND METHODS A total of 26 cases were included in this study. Any pediatric patient with normal coagulation parameters and a fractured catheter fragment was included in this study. Other intravascular foreign bodies related to interventional devices and/or pacemaker/implantable cardiac defibrillator leads were excluded from this study. RESULTS Twenty-six patients, of whom 25 had oncologic diseases and 1 had a ventriculoatrial shunt, were included. The median age was 83.5 months (between 20 mo and 18 y) at treatment.Superior vena cava (9 cases), followed by the right atrium (5 cases), were the most two common sites of embolization for cardiovascular foreign bodies. The success rate of percutaneous retrieval was 92.3% in all patients. There were neither complications nor deaths. The retrieval technique revealed a predisposition for extraction through the femoral vein (96.1%) and using snare techniques (100%). Additional catheters like pigtail, National Institutes of Health, or ablation catheters were used for stabilization in selective cases in which the permanent central venous fragments stuck to the vessels. A tractional maneuver and capturing the ruptured material in the middle were other trick points for successful retrieval. Patients were asymptomatic in 76.9% of cases (20/26). CONCLUSION Percutaneous retrieval of cardiovascular foreign bodies is a reasonable, safe, and effective way in children when the catheter fragments are free and mobile. It should be considered the preferred treatment option instead of surgery. In patients where catheter fragments are stuck and are adherent to vessels, it could be left, and followed up by anticoagulation. Novel techniques accompanied by an experienced team could be helpful in difficult cases.

Abstract
OBJECTIVE Small airway dysfunction is a pathological component of chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF), and impulse oscillometry is an easy-to-administer, effort-independent non-invasive test reflecting small airway dysfunction. We aimed to compare the impulse oscillometry (IOS) measurements between COPD and IPF patients and investigate their correlation with severity of both diseases and other conventional parameters. PATIENTS AND METHODS This was a prospective, longitudinal study. We longitudinally evaluated the baseline demographic characteristics, COPD Assessment Test (CAT) and modified Medical Research Council (mMRC) dyspnea scale, Pulmonary Function Test (PFT), Carbon Monoxide Diffusing Capacity (DLCO), Hemogram and Impulse Oscillometry measurements of the patients diagnosed with COPD and IPF. RESULTS The study included 60 IPF patients and 48 COPD patients. The CAT and mMRC scores were higher in COPD patients. The majority of COPD patients were classified into Category B (46%), while 68% of IPF patients had Stage 1 GAP. The mean FEF 25-75%, which is typically considered to reflect small airway disease, was 93% in IPF patients, while it was significantly lower in COPD patients (29%). Impulse oscillometry measurements were consistent with spirometry parameters. IOS resistance and reactance values were significantly higher in COPD patients than in IPF patients. CONCLUSIONS IOS is advantageous in COPD and IPF patients who cannot exhale due to severe dyspnea, as it is easy to administer and reflects small airway resistance better. Diagnosis of small airway dysfunction may be beneficial in the management of patients with IPF and COPD.

Abstract
Background Pathogenic variants in KITLG, a crucial protein involved in pigmentation and neural crest cell migration, cause non‐syndromic hearing loss, Waardenburg syndrome type 2, familial progressive hyperpigmentation and familial progressive hyper‐ and hypopigmentation, all of which are inherited in an autosomal dominant manner. Objectives To describe the genotypic and clinical spectrum of biallelic KITLG‐variants. Methods We used a genotype‐first approach through the GeneMatcher data sharing platform to collect individuals with biallelic KITLG variants and reviewed the literature for overlapping reports. Results We describe the first case series with biallelic KITLG variants; we expand the known hypomelanosis spectrum to include a ‘sock‐and‐glove‐like’, symmetric distribution, progressive repigmentation and generalized hypomelanosis. We speculate that KITLG biallelic loss‐of‐function variants cause generalized hypomelanosis, whilst variants with residual function lead to a variable auditory‐pigmentary disorder mostly reminiscent of Waardenburg syndrome type 2 or piebaldism. Conclusions We provide consolidating evidence that biallelic KITLG variants cause a distinct auditory‐pigmentary disorder. We evidence a significant clinical variability, similar to the one previously observed in KIT‐related piebaldism.

Abstract
AIM The aim of our study was to evaluate the safety and efficiency of the 'figure-of-eight' suture among children and young adults with congenital heart defects who underwent interventional procedures, in patients with structurally normal hearts who underwent electrophysiological study and in haemodynamically impaired children and newborns. We also reported a novel femoral haemostasis method in patients with a central catheter by modifying the 'figure-of-eight' suture around the catheter for haemorrhage control. METHOD Between 2015 and 2018, a total of 100 'figure-of-eight' sutures were performed in 90 patients (48 males, 42 females) where the median age was 12.5 years (minimum 3 days, maximum 22 years). The procedures were diagnostic angiography (n = 6), radiofrequency and/or cryoablation (n = 7) and interventional procedures (n = 87). RESULT Haemostasis was achieved in 89 of 90 patients. Haemostasis could not be achieved in one malnourished patient due to lack of subcutaneous tissue. There were no major complications. A bullous skin lesion and minor bleeding were the only complications seen in two patients. A central catheter was inserted in eight patients using the modified 'figure-of-eight' suture technique. CONCLUSION The 'figure-of-eight' suture is a safe and effective method for femoral venous haemostasis in patients who require large sheaths for procedures, in those using high-dose heparin and in haemodynamically unstable children who need cardiac catheterisation.

Abstract
BACKGROUND In pediatric patients with documented narrow QRS tachycardia that is suggestive of atrioventricular nodal reentrant tachycardia (AVNRT) and not inducible in electrophysiological study (EPS), empiric slowpathway ablation (ESPA) may be considered. There is limited data in children about this topic. METHODS Seventy-nine patients who underwent cryoablation and/or radiofrequency ablation (RFA) for presumed AVNRT between January 2010 and January 2020, with no inducible tachycardia and no other tachycardia mechanisms during EPS, were included in this study. RESULTS The age was between 6 and 18 years. All patients had no structural heart disease. Preablation exhibited sustained SP conduction for all patients. In all cases, the ablation end points were prolongation in wenckebach cycle length (WBCL) with loss of cross and/or jump, and/or echo beat. The end points were not achieved in two patients. Overall, the mean basal WBCL increased to 351 ms (240-500 ms) from 301.3 ms (180-420 ms), evident in the non-recurrence group. Nine patients had a transient AV block that improved. We followed the patients without medication for about 46.9 months (8 months to 10 years). Palpitations occurred again in 9 of 77 patients (clinical recurrence rate 9/79 - 11.3%). The documented ECG recurrence rate was 1.2% (1/79). In the non-recurrence group, WBCL prolongation was higher and mean age was lower than in the recurrence group (13.075 vs. 15.33 years). CONCLUSION In cases with presumed AVNRT, ESPA seems to be a reasonable and safe way. In our study, we found our procedural success rate as 97.4% and follow-up recurrence rate as 12.6% (9+1/79).

Abstract
AIM Information regarding the Neutrophil/Lymphocyte ratio (NLR) in sarcoidosis and the data from studies recommending its use as an indicator of inflammation and in the differential diagnosis and prognosis, are limited. With this study, it was aimed to obtain data regarding the NLR level in the patients at the time of presentation to the hospital and to determine the characteristics of patients in whom the NLR value was > 2. RESULTS During the study period, of the 3434 patients with the sub-diagnosis of D86, 1300 cases whose complete blood count values had been recorded at the time of presentation were included in the study. Of the cases, 40 % were pulmonary sarcoidosis, 7 % were pulmonary sarcoidosis with sarcoidosis of the lymph nodes, 8 % were lymph node sarcoidosis, 1 % were sarcoidosis, of other combined areas, and 40 % of the cases were sarcoidosis that were unspecified. The F/M of the cases were 947/353, and the average age of the cases was 44. When the sarcoidosis groups were grouped into NLR < 2 (Group 1) and NLR ≥ 2 (Gorup 2), 27 % were Group 1, 73 % were Group 2, and a significant correlation was found between the two groups. When the inflammatory indicators were compared with NLR, the PLT/MPV was found to be statistically insignificant, and the ACE, ESR and CRP were found to be statistically significant. CONCLUSION The Neutrophil/Lymphocyte ratio in the complete blood count, which is an easy and cheap test, can be used as an indicator of inflammation in Sarcoidosis. In clinical practice, wide-based studies comprising the activity and the staging in the prognosis of sarcoidosis are required (Tab. 2, Fig. 2, Ref. 26).

Abstract
We present an 18-day old boy with bilateral cervical cutaneous defect in the retroauricular region, low-set and posteriorly rotated ears, bilateral microphtalmia and bilateral pseudocleft of the upper lip. Histopathological evaluation of cervical cutaneous defect showed ulceration on the surface and ectopic thymus tissue in the deep dermis with cortex, medulla and Hassal's corpuscles. Clinical findings led to the diagnosis of Branchio-oculo-facial syndrome, characterized by branchial defects (erythematous cutaneous defects in cervical region), ocular anomalies (microphthalmia, anophthalmia, lacrimal duct obstruction, coloboma, cataract, ptosis) and facial defects (cleft lip and/or palate, pseudocleft or abnormal philtrum). DNA sequencing showed a novel heterozygous mutation, c.731T>C (p.L244P), in TFAP2A gene confirming the diagnosis of this rare autosomal dominant developmental disorder with variable clinical findings.

Abstract
Hereditary deafness is a genetically heterogeneous phenotype for which more than 100 genomic loci have been identified thus far. By analysis of a consanguineous Palestinian family, GPSM2 was recently discovered to be the cause of autosomal recessive non-syndromic hearing loss DFNB82. Here, we report a second truncating mutation, GPSM2 p.Q562X, identified via autozygosity mapping in a consanguineous Turkish family. This report provides evidence for allelic heterogeneity of GPSM2 and confirms its causative role for non-syndromic deafness.

Abstract
A 78-year-old man with a history of aorta-femoral graft operation was admitted to the hospital with symptoms of syncope, melena and haematemesis. He reported several episodes of melena during the previous year for which he underwent repeated gastro-intestinal endoscopic examinations, which were unable to show the site of the gastro-intestinal bleeding. The third upper gastro-intestinal endoscopic examination disclosed a yellowish ulcerative lesion with irregular borders in the third part of the duodenum, which was considered to be a fistula, between the aorta and the duodenum. The patient underwent an explorative operation that revealed an intact aortic graft, firmly adherent to the duodenal wall, and the duodenum that was eroded in the third portion. The duodenum was transected and a duodenoduodenostomy was performed. Although re-bleeding did not occur, the patient died of sepsis eight days after the operation. Aorto-enteric fistulae can be missed due to the common practice of limiting the endoscopic examination to the second part of the duodenum and not considering them in the differential diagnosis of gastro-intestinal bleeding because of their rarity. Possibly, a number of prior endoscopic examinations may be inconclusive until a correct diagnosis is reached in most of the cases.

Abstract
Using Affymetrix 10K arrays, we searched for regions of homozygosity in 51 Turkish families including at least three members with either congenital or prelingual autosomal recessive non-syndromic sensorineural hearing loss (ARNSSNHL), and identified four families whose deafness mapped to the DFNB6 locus on 3p21 containing the TMIE gene. Mutation analysis revealed the p.R84W mutation in all four families. Screening of this mutation in 254 families with ARNSSNHL, without GJB2 mutations, revealed four additional affected families. A novel mutation was found in a non-complementary marriage between a deaf couple who were homozygous for p.R84W and p.W57X, respectively with two affected children who were compound heterozygotes. Six of the TMIE families originated from southeastern Anatolia, making p.R84W a common cause of hearing loss in that region with a relative frequency of 10.3% (95% CI is 2.5-18.1%). The overall prevalence of the p.R84W mutation in ARNSSNHL in Turkey is 2.4% (95% CI is 0.7-4.0%). Genotyping of single-nucleotide polymorphisms flanking the TMIE gene revealed a conserved haplotype, suggesting a single origin for p.R84W from a common ancestor 1250 years ago (95% CI is 650-2500 years). We conclude that p.R84W could be a common mutation in other Middle Eastern populations and should be included in mutation screening offered to individuals with ARNSSNHL.

Abstract
SETTING Sureyyapasa Chest Diseases and Thoracic Surgery Training Hospital, Istanbul, Turkey. OBJECTIVE To determine levels of Mycobacterium tuberculosis resistance to first-line drugs in patients with pulmonary tuberculosis (PTB). DESIGN Between 1 January and 31 December 2005, all hospitalised PTB patients with culture-positive M. tuberculosis specimens and corresponding drug susceptibility tests (DST) for isoniazid (INH), rifampicin (RMP), streptomycin (SM) and ethambutol, routinely performed for every tuberculosis (TB) case at our centre, were included. RESULTS Of a total of 1513 cases, 1277 (84.4%) were new and 236 (15.6%) were previously treated cases. Of the 1513 isolates, 290 (19%) isolates were resistant to at least one of the drugs tested. Resistance among new and previously treated cases was respectively 16.3% (209 of 1277) and 34.3% (81/236). Any SM resistance and any INH resistance were the most common drug resistance in new cases, while any RMP resistance was the most common drug resistance in previously treated cases. Multidrug resistance was detected in 3.2% (n = 41) of new cases and in 13.5% (n = 32) of previously treated cases. CONCLUSION Planning for TB control requires an assessment of the number and distribution of drug-resistant cases, with laboratories providing accurate and reliable results.

Abstract
Homozygous mutations in the fibroblast growth factor 3 (FGF3) gene have recently been discovered in an autosomal recessive form of syndromic deafness characterized by complete labyrinthine aplasia (Michel aplasia), microtia, and microdontia (OMIM 610706 - LAMM). In order to better characterize the phenotypic spectrum associated with FGF3 mutations, we sequenced the FGF3 gene in 10 unrelated families in which probands had congenital deafness associated with various inner ear anomalies, including Michel aplasia, with or without tooth or external ear anomalies. FGF3 sequence changes were not found in eight unrelated probands with isolated inner ear anomalies or with a cochlear malformation along with auricle and tooth anomalies. We identified two new homozygous FGF3 mutations, p.Leu6Pro (c.17T>C) and p. Ile85MetfsX15 (c.254delT), in four subjects from two unrelated families with LAMM. The p.Leu6Pro mutation occurred within the signal site of FGF3 and is predicted to impair its secretion. The c.254delT mutation results in truncation of FGF3. Both mutations completely co-segregated with the phenotype, and heterozygotes did not have any of the phenotypic findings of LAMM. Some affected children had large skin tags on the upper side of the auricles, which is a distinctive clinical component of the syndrome. Enlarged collateral emissary veins associated with stenosis of the jugular foramen were noted on computerized tomographies of most affected subjects with FGF3 mutations. However, similar venous anomalies were also detected in persons with non-syndromic Michel aplasia, suggesting that a direct causative role of impaired FGF3 signaling is unlikely.

Abstract
Cardiotoxicity is a rare but serious side effect of 5-flourouracil (5-FU). The cardiotoxicity incidence of 5-FU is increasing with its frequent use in chemotherapy protocols. To explain the mechanism of this cardiotoxicity, many theories have been suggested by different authors. Most commonly, coronary artery vasospasm and flouroacetate,a toxic metabolite of 5-FU, are considered responsible for the toxicity. Ischemic symptoms and signs related to 5-FU are observed during the late phase of the administration of the drug. The close and careful monitorization of all the patients, especially the ones with pre-existent coronary artery disease, during 5-FU infusion is mandatory. Because there is not a single and effective modality of treatment or prophylaxis for 5-FU cardiotoxicity, the patients should be selected carefully for 5-FU administration and 5-FU infusion should be stopped as soon as a symptom is encountered.
