Comparison of anesthesia management in transcatheter aortic valve implantation: a retrospective cohort study.

BACKGROUND AND OBJECTIVES: We aimed to investigate the effects of two different anesthetic techniques in our patients who underwent transcatheter aortic valve implantation (TAVI). METHODS: In this study, 303 patients who underwent TAVI procedure with a diagnosis of severe aortic stenosis between January 1, 2012 and December 31, 2018 were retrospectively evaluated. The patients were divided according to the type of anesthesia given during each procedure as; general anesthesia (GA), local anesthesia (LA). RESULTS: LA was preferred in 245 (80.8%) of 303 patients who underwent TAVI, while GA was preferred in 58 patients (19.1%). Median ages ​​of our patients who received LA and GA were 83 and 84, respectively. The procedure and anesthesia durations of the patients in the GA group were longer than the LA group (p< 0.00001, p < 0.00001, respectively). Demographic and pre-operative clinical data were similar in comparison between two groups (p > 0.05) except for peripheral artery disease. Hypertension was the most common comorbidity in both groups. While the number of inotrope use was significantly higher in patients who received GA (p < 0.00001), no significant differences were found between LA and GA patients in terms of major complications and mortality (p > 0.05). Intensive care and hospital stays were significantly shorter in the LA group (p = 0.001, p = 0.023, respectively). CONCLUSION: The anesthetic technique of TAVI procedure did not have a significant effect on outcomes including; complications, mortality and success of the procedure. LA provides shorter duration of procedure and hospital stay.

Presystolic Wave is Associated with Subclinical Left Ventricular Dysfunction Assessed by Myocardial Performance Index in Type 2 Diabetes Mellitus.

BACKGROUND: Myocardial performance index (MPI), demonstrates both systolic and diastolic functions of the left ventricle. Presystolic wave (PSW) is frequently detected on Doppler examination of the left ventricular outflow tract and possible mechanism of PSW is impaired LV compliance and left ventricular stiffness. OBJECTIVE: To investigate the relationship between PSW and MPI in type 2 diabetic patients. METHOD: A total of 129 type 2 diabetic patients were included in this study. Patients were divided into two groups according to the presence of PSW on Doppler echocardiography. There were 90 patients (38 male, mean age 57.77 ± 10.91 years) in the PSW-positive group and 39 patients (13 male; mean age: 55.31 ± 11.29 years) in the PSW-negative group. The p values of < 0.05 were considered statistically significant. RESULTS: MPI was higher in PSW- positive group (0.63 ± 0.17vs 0.52 ± 0.13, p < 0.001). In addition, subclinical left ventricle dysfunction (LVD) was higher in the PSW- positive group (p = 0.029). Univariate analysis showed that the presence of PSW associated with abnormal MPI (p = 0.031). Pearson correlation analysis showed that PSW velocity correlated with MPI (r: 0.286, p = 0.006). CONCLUSION: Presence of the PSW on Doppler examination was associated with subclinical LV dysfunction in patients with DM type 2. This easy-to-perform echocardiographic parameter may be related to subclinical LVD among patients with type 2 DM.

Value of coronary artery calcium score to predict severity or complexity of coronary artery disease.

BACKGROUND: Prediction of severity or complexity of coronary artery disease (CAD) is valuable owing to increased risk for cardiovascular events. Although the association between total coronary artery calcium (CAC) score and severity of CAD, Gensini score was not used, it has been previously demonstrated. There is no information about the association between total CAC score and complexity of CAD. OBJECTIVES: To investigate the association between severity or complexity of coronary artery disease (CAD) assessed by Gensini score and SYNTAX score (SS), respectively, and coronary artery calcium (CAC) score, which is a noninvasive method for CAD evaluation in symptomatic patients with accompanying significant CAD. METHODS: Two-hundred-fourteen patients were enrolled. Total CAC score was obtained before angiography. Severity and complexity of CAD was assessed by Gensini score and SS, respectively. Associations between clinical and angiographic parameters and total CAC score were analyzed. RESULTS: Median total CAC score was 192 (23.0-729.8), and this was positively correlated with both Gensini score (r: 0.299, p<0.001) and SS (r: 0.577, p<0.001). At multivariate analysis, it was independently associated with age (ß: 0.154, p: 0.027), male gender (ß: 0.126, p: 0.035) and SS (ß: 0.481, p<0.001). Receiver-operating characteristic (ROC) curve analysis revealed a cut-off value>809 for SS>32 (high SS tertile). CONCLUSION: In symptomatic patients with accompanying significant CAD, total CAC score was independently associated with SS and patients with SS>32 may be detected through high Agatston score.

Valor do escore de calcio coronariano para prever a gravidade ou complexidade da doenca arterial coronariana / Value of coronary artery calcium score to predict severity or complexity of coronary artery disease

FUNDAMENTO: A previsão de gravidade ou complexidade da doença arterial coronariana (DAC) é valiosa devido ao aumento do risco de eventos cardiovasculares. Embora a associação entre o escore do cálcio arterial coronariano (CAC), e a gravidade da DAC pelo escore Gensini não tenha sido utilizado, já foi anteriormente demonstrado. Não há informações sobre a associação entre o escore do CAC total e a complexidade da DAC. OBJETIVOS: Investigar a associação entre a gravidade ou complexidade da doença arterial coronariana (DAC), avaliada pelo escore Gensini e SYNTAX (SS), respectivamente, e o escore do cálcio arterial coronariano (CAC), um método não invasivo para avaliação de DAC em pacientes sintomáticos com DAC significativa. MÉTODOS: Duzentos e quatorze pacientes foram incluídos. A pontuação total do CAC foi obtido antes da angiografia. A severidade e complexidade da DAC foram avaliadas pelo escore Gensini e SS, respectivamente. Foram analisadas as associações entre parâmetros clínicos e angiográficos e o escore total do CAC. RESULTADOS: A mediana do escore total do CAC foi de 192 (23,0-729,8), e correlacionou-se positivamente com ambos os escores Gensini (r: 0,299, p < 0,001) e ES (r: 0,577, p < 0,001). Na análise multivariada associou-se independentemente com a idade (ß: 0,154, p: 0,027), sexo masculino (ß: 0,126, p: 0,035) e ES (ß: 0,481, p < 0,001). A análise da curva ROC (Receiver Operating Characteristics) revelou um valor de corte > 809 para ES > 32 (tercil de SS alto). CONCLUSÃO: Em pacientes sintomáticos com DAC significativa, o escore total de CAC foi independentemente associado com SS e os pacientes com SS > 32 podem ser detectados através de escore Agatston alto. .
