RESUMO

PURPOSE: Association between S. gallolyticus infective endocarditis (IE) and malignant lesions of the gastrointestinal tract is well described. We hypothesize that other enteropathogenic microorganisms, such as S. viridans and E. faecalis are also related with colorectal pathology. Our aim is to determine the frequency of focal colorectal FDG deposits, suggestive of tumoral lesions and their correlation with colorectal pathology, in patients with infection caused by different commensal microorganisms of the gastrointestinal tract. METHODS: We retrospectively examined 61 patients diagnosed with bacteremia (BSI) and IE (possible or definite) according to Duke's criteria, caused by enteropathogenic microorganisms, who underwent a full-body [18F]FDG-PET/CT in our institution. We looked for colorrectal FDG deposits and morphological lesions. All IE patients underwent a complete colonoscopy and the histological results were classified into four groups: malignant lesion, premalignant lesion, benign lesion and no lesion. We evaluated the correlation between the findings of the [18F]FDG-PET/CT with the histopathological diagnosis and the involved microorganism. RESULTS: PET/CT detected 20 colorectal FDG deposits (32.79%-OR: 47.28), 2 within bacteriemic patients (16.7%) confirmed as malignant and premalignant lesions and 18 in IE group (36.6%), 17 of them corresponding to colorrectal pathology: 11 malignant, 5 premalignant and 1 benign lesions. In the IE subgroup, the colonoscopy detected colorectal lesions in 51.02% of the patients: 11malignant, 8premalignant and 6benign. We found a higher incidence of colorectal FDG deposits in Streptococcus spp. subgroup. Regarding the anatomopathological colonic findings there was a predominance of patients affected by S. viridans, followed by E. faecalis and S. gallolyticus. CONCLUSION: Patients studied by PET/CT for systemic infection, especially IE, caused by S. viridans or E. faecalis, in addition to S. gallolyticus, show a greater probability of presenting incidental colorectal FDG deposits, mostly corresponding to malignant or pre-malignant lesions. Therefore, it is necessary to carry out an exhaustive search of possible colorectal foci in these exams.

RESUMO

INTRODUCTION: Spain is one of the countries with the lowest rates of revascularisation and highest ratio of percutaneous coronary intervention (PCI) to coronary artery bypass grafting (CABG). OBJECTIVES: To investigate the changes and trends in the two revascularisation procedures between 1998 and 2017 in Spain. DESIGN: Retrospective cohort study. Analysis of in-hospital outcomes. SETTING: Minimum basic data set from the Spanish National Department of Health: mandatory database collecting information of patients who are attended in the Spanish public National Health System. PARTICIPANTS: 603 976 patients who underwent isolated CABG or PCI in the Spanish National Health System. The study period was divided in four 5-year intervals. Patients with acute myocardial infarction on admission were excluded. PRIMARY AND SECONDARY OUTCOMES: We investigated the volume of procedures nationwide, the changes of the risk profile of patients and in-hospital mortality of both techniques. RESULTS: We observed a 2.2-fold increase in the rate of any type of myocardial revascularisation per million inhabitants-year: 357 (1998) to 776 (2017). 93 682 (15.5%) had a coronary surgery. PCI to CABG ratio rose from 2.2 (1998-2002) to 8.1 (2013-2017). Charlson's index increased by 0.8 for CABG and 1 for PCI. The median annual volume of PCI/hospital augmented from 136 to 232, while the volume of CABG was reduced from 137 to 74. In the two decades, we detected a significant reduction of CABG in-hospital mortality (6.5% vs 2.6%, p<0.001) and a small increase in PCI (1.2% vs 1.5%, p<0.001). Risk adjusted mortality rate was reduced for both CABG (1.51 vs 0.48, p<0.001), and PCI (1.42 vs 1.05, p<0.001). CONCLUSION: We detected a significant increase in the volume of revascularisations (particularly PCI) in Spain. Risk-adjusted in-hospital mortality was significantly reduced.

RESUMO

OBJECTIVES: Several risk prediction models have been developed to estimate the risk of mortality after valve surgery for active infective endocarditis (IE), but few external validations have been conducted to assess their accuracy. We previously developed a systematic review and meta-analysis of the impact of IE-specific factors for the in-hospital mortality rate after IE valve surgery, whose obtained pooled estimations were the basis for the development of a new score (APORTEI). The aim of the present study was to assess its prognostic accuracy in a nationwide cohort. METHODS: We analysed the prognostic utility of the APORTEI score using patient-level data from a multicentric national cohort. Patients who underwent surgery for active IE between 2008 and 2018 were included. Discrimination was evaluated using the area under the receiver operating characteristic curve, and the calibration was assessed using the calibration slope and the Hosmer-Lemeshow test. Agreement between the APORTEI and the EuroSCORE I was also analysed by Lin's concordance correlation coefficient (CCC), the Bland-Altman agreement analysis and a scatterplot graph. RESULTS: The 11 variables that comprised the APORTEI score were analysed in the sample. The APORTEI score was calculated in 1338 patients. The overall observed surgical mortality rate was 25.56%. The score demonstrated adequate discrimination (area under the receiver operating characteristic curve = 0.75; 95% confidence interval 0.72-0.77) and calibration (calibration slope = 1.03; Hosmer-Lemeshow test P = 0.389). We found a lack of agreement between the APORTEI and EuroSCORE I (concordance correlation coefficient = 0.55). CONCLUSIONS: The APORTEI score, developed from a systematic review and meta-analysis, showed an adequate estimation of the risk of mortality after IE valve surgery in a nationwide cohort.

RESUMO

Herein, we present the case of a 66-year-old man with an inflammatory myofibroblastic tumour. An inflammatory myofibroblastic tumour is an extremely rare entity, with only 60 cases having been reported to date in the literature. The origin of this type of tumour is unknown and the treatment of choice is surgical resection. We present the surgical technique of our case and a review of the literature regarding this tumour. This is the first case described in a man above 60 years of age with a tumour located in the right ventricle.

RESUMO

OBJECTIVES: The development of new percutaneous and surgical techniques has reduced the risk associated with aortic valve replacement procedures. We present the results of a Spanish register after initiating a programme for sutureless prostheses in moderate-high-risk patients. METHODS: This prospective multicentre study was carried out from November 2013 to November 2016. Data were obtained from 448 patients in whom a Perceval S prosthesis was implanted. RESULTS: The mean age was 79.24 (standard deviation [SD] 4.1) years, and 61.2% were women. The estimated EuroSCORE I log risk was 11.15% (SD 7.6), with an observed mortality of 4.4% (20 patients). Isolated aortic valve replacement was performed on 69.26% of patients, with 64% involving ministernotomy. The incidence of neurological events was 2%, with 2 permanent cerebrovascular accidents, and 41 (9.2%) patients were implanted with a permanent endocavitary pacemaker. At discharge, 12 (2.6%) patients presented minimal periprosthetic leakage, and 4 (0.89%) patients had moderate leakage. There were 3 reinterventions during follow-up (2 endocarditis and 1 dysfunction due to periprosthetic leak progression). The mean gradient at discharge, 6 months and 1 year was 12.94 (SD 5.3) mmHg, 12.19 (SD 4.7) mmHg and 11.77 (SD 4.7) mmHg, respectively; 59.4% of the patients were octogenarians, with a survival rate of 98% at both 6 months and 1 year at discharge. There was neither valve migration nor early structural degeneration. The mean follow-up was 12 ± 3 months. The 6-month and 1-year mortality was 1.4% and 2.1%, respectively. CONCLUSIONS: This is a prospective multicentric study on the largest cohort of patients with sutureless valves conducted in Spain to date. It is a reproducible procedure that has enabled surgery on patients with a moderate-high risk with low morbidity and mortality, providing good haemodynamic results.

RESUMO

BACKGROUND: Direct injury to the right coronary artery as a result of reparative operation on the tricuspid valve is a rare, probably underdiagnosed, but serious complication, which often involves dramatic clinical consequences. So far, only five cases have been described in the literature. METHODS: We describe our single-center experience of this complication, and review and analyze relevant clinical and anatomic considerations related to this entity. Cases previously reported in the literature were also reviewed. RESULTS: We describe four cases of direct injury to the right coronary artery in patients undergoing tricuspid annuloplasty (DeVega annuloplasty, 3; ring annuloplasty, 1) in our institution since 2005. All patients had right ventricular dilatation and severely dilated tricuspid annulus. Right coronary artery occlusion always occurred between the right marginal artery and the crux of the heart. Patients presented with hemodynamic or electrical instability. Coronary flow could be restored in 2 patients (percutaneously 1; surgically 1), both of whom finally survived, while it was not technically possible in the other 2 (1 died). CONCLUSIONS: Occlusion of the right coronary artery in patients undergoing tricuspid annuloplasty is a rare complication that may occur if great annulus dilatation is present, thus altering both normal annular geometry and the relationship between the right coronary artery and the tricuspid annulus, particularly when DeVega annuloplasty is performed. Such an entity should be considered in the immediate postoperative period in an unstable patient, especially when complementary tests support this diagnosis. Prompt recognition and treatment can positively affect the patient's outcome, most often by means of an emergency revascularization strategy.
