Abstract: Patients presenting with aortic stenosis and atrial fibrillation (AF) undergoing transcatheter aortic valve replacement (TAVR) are commonly at increased risk for stroke and bleeding complications. Concomitant left atrial appendage occlusion (LAAO) after TAVR may be an alternative to oral anticoagulation (OAC). Between 2018 and 2022, 7 consecutive patients who were ineligible for OAC underwent simultaneous TAVR and LAAO. The mean age was 84.9 ± 4.9 years. The mean CHA2DS2-VASc, HAS-BLED, and STS predicted risk of mortality scores were 5.9 ± 0.7, 3.9 ± 1.1, and 8.8 ± 3.4%, respectively. The median follow-up time was 23 (1 to 27) months. All procedures achieved technical success and no adverse events were observed during follow-up. This case series shows that concomitant TAVR and LAAO is feasible and safe among patients with severe aortic stenosis and AF who are deemed ineligible for OAC. Learning objectives: Atrial fibrillation is the most common arrhythmia in the transcatheter aortic valve replacement (TAVR) population. In those who experience major or life-threatening bleeding, mortality is doubled. We report a case series of 7 concomitant left atrial appendage occlusions (LAAO) after TAVR in patients ineligible for oral anticoagulation. All procedures achieved technical success and no adverse events were observed. The simultaneous approach with TAVR and LAAO was feasible and safe in this case series.2022-01-01T00:00:00ZDelayed left main coronary obstruction following transfemoral inovare transcatheter aortic valve replacement: A challenging case

Title: Delayed left main coronary obstruction following transfemoral inovare transcatheter aortic valve replacement: A challenging case

Abstract: Coronary obstruction is an uncommon and severe complication after a transcatheter aortic valve replacement (TAVR), that occurs during the procedure in the vast majority of patients. In the present case even in the absence of classic risk factors, an acute coronary syndrome occurred one day after TAVR. Selective angiography revealed a severe left main ostium obstruction by the bulky native leaflet calcification. This is the first case of delayed presentation of coronary obstruction with a transfemoral balloon-expandable valve using the Inovare bioprosthesis (Braile Biomedica, Brazil). In addition, after drug-eluting stent placement in the left main coronary, intravascular ultrasound revealed severe stent underexpansion, so that a second layer of a bare-metal stent and high-pressure balloon post-dilatation was necessary to improve the final result. The patient was discharged after 7 days, and at the 6-month follow-up remained asymptomatic. <Learning objective: This case illustrates an unusual cause of an acute coronary syndrome 24 h after a transcatheter aortic valve replacement. This is the first report of this severe complication with delayed presentation following the balloon-expandable Inovare bioprosthesis. Even in the absence of classic risk factors this complication may occur, and percutaneous coronary intervention is feasible in the vast majority of cases, often requiring various percutaneous techniques and intravascular image to improve outcomes.>2022-01-01T00:00:00ZAdverse events in the postoperative period of cardiac surgery in a pediatric intensive care unit: the contribution of the VIS score and the RACHS-1

Title: Adverse events in the postoperative period of cardiac surgery in a pediatric intensive care unit: the contribution of the VIS score and the RACHS-1

Abstract: Objective: To eval uat e t he occurrence of adverse events in the postoperative period of cardiac surgery in a pediatric intensive care unit and to find any patient characteristics that can predict such events. Methods: This was a historical cohort study of patients recovering in the pediatric intensive care unit for the first 7 days after cardiac surgery between April and December 2019, by reviewing the medical records. The following were reviewed: demographic, clinical, and laboratory characteristics; patient severity scores; and selected adverse events, grouped into device-related, surgical, and nonsurgical. Results: A total of 238 medical records were i ncl uded. At l east one adverse event occurred in 110 postoperative patients (46.2%). The total number of adverse events was 193 (81%). Vascular catheters were the most common cause, followed by cardiac arrest, bleeding, and surgical reexploration. In the univariate analysis, the vasoactive-inotropic score (VIS), Risk Adjustment in Congenital Heart Surgery (RACHS-1) score, age, Pediatric Index of Mortality (PIM-2), cardiopulmonary bypass and aortic clamping duration were significantly associated with adverse events. In the multivariate analysis, VIS ≥ 20 (OR 2.90; p = 0.004) and RACHS-1 ≥ 3 (OR 2.11; p = 0.019) were significant predictors, while age and delayed sternal closure showed only trends toward significance. To predict the occurrence of adverse events from VIS and RACHS-1, the area under the curve was 0.73 (95%CI 0.66-0.79). Conclusion: Adverse events were quite frequent in children after cardiac surgery, especially those related to devices. The VIS and RACHS-1, used together, predicted the occurrence of adverse events well in this pediatric sample.2023-01-01T00:00:00ZRare association between giant-cell aortitis and giant-cell aortic valvulitis

Title: Rare association between giant-cell aortitis and giant-cell aortic valvulitis
Authors: LUZURIAGA, G. C. J.; DIAS, R. R.; SANTIAGO, J. A. D.; JUNIOR, V. M.; ISHIKAWA, W. Y.; FERNANDES, F.; AIELLO, V. D.
Abstract: Giant cell arteritis (GCA) is a type of chronic vasculitis that affects medium and large-caliber arteries, frequently related to aortic involvement and, consequently, to aneurysm formation. However, associated valvulitis with giant cells is uncommon. We describe the case of a 50-year-old female patient with aortic aneurysm and valvular insufficiency, whose anatomopathological examination revealed giant-cell aortic valvulitis associated with giant cell aortitis.2023-01-01T00:00:00Z
