4to. Congreso Internacional de Ciencia, Tecnología e Innovación para la Sociedad. Memoria académica
Este volumen acoge la memoria académica de la Cuarta edición del Congreso Internacional de Ciencia, Tecnología e Innovación para la Sociedad, CITIS 2017, desarrollado entre el 29 de noviembre y el 1 de diciembre de 2017 y organizado por la Universidad Politécnica Salesiana (UPS) en su sede de Guayaquil.
El Congreso ofreció un espacio para la presentación, difusión e intercambio de importantes investigaciones nacionales e internacionales ante la comunidad universitaria que se dio cita en el encuentro. El uso de herramientas tecnológicas para la gestión de los trabajos de investigación como la plataforma Open Conference Systems y la web de presentación del Congreso http://citis.blog.ups.edu.ec/, hicieron de CITIS 2017 un verdadero referente entre los congresos que se desarrollaron en el país.
La preocupación de nuestra Universidad, de presentar espacios que ayuden a generar nuevos y mejores cambios en la dimensión humana y social de nuestro entorno, hace que se persiga en cada edición del evento la presentación de trabajos con calidad creciente en cuanto a su producción científica.
Quienes estuvimos al frente de la organización, dejamos plasmado en estas memorias académicas el intenso y prolífico trabajo de los días de realización del Congreso Internacional de Ciencia, Tecnología e Innovación para la Sociedad al alcance de todos y todas
Emergent Percutaneous Closure of Left Ventricular Free Wall Perforation During Transcatheter Aortic Valve Replacement
Comparison of 30-day outcomes of coronary artery bypass grafting surgery verus hybrid coronary revascularization stratified by SYNTAX and euroSCORE
ObjectiveThe optimal treatment of multivessel coronary artery disease is not well established. Hybrid coronary revascularization by combining the left internal mammary artery–left anterior descending artery graft and drug-eluting stents in non–left anterior descending artery territories might offer superior results compared with sole coronary artery bypass grafting or sole percutaneous coronary intervention.MethodsWe retrospectively analyzed the 30-day outcomes of 381 consecutive patients undergoing coronary artery bypass grafting (n = 301) vs hybrid coronary revascularization (n = 80). In a 2 × 2 matrix, the 2 groups were stratified by the Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery (SYNTAX) score (≤32 vs ≥33) and the European System for Cardiac Operative Risk Evaluation (euroSCORE) (<5 vs ≥5). The composite endpoint (death from any cause, stroke, myocardial infarction, low cardiac output syndrome) and secondary endpoints (worsening postprocedural renal function and bleeding) were determined.ResultsAfter stratification using the SYNTAX and the euroSCORE, the preoperative characteristics were similar within the 4 groups, except for the ≥33 SYNTAX/>5 euroSCORE. The hybrid coronary revascularization patients were older (77 vs 65 years, P = .001). The postoperative outcomes using combined SYNTAX and the euroSCORE stratification showed a similar rate of the composite endpoint for all groups except for patients with ≥33 SYNTAX/>5 euroSCORE (0% for the coronary artery bypass grafting group vs 33% for the hybrid coronary revascularization group, P = .001). An analysis of the secondary endpoint showed similar results across all groups, except for in the ≥33 SYNTAX/>5 euroSCORE group, in which bleeding (re-exploration for bleeding and transfusion >3 packed red blood cell units per patient) was 44% in the hybrid coronary revascularization group vs 11% in the coronary artery bypass grafting group (P = .05).ConclusionsHybrid coronary revascularization is a safe alternative to coronary artery bypass grafting in many patients with multivessel coronary artery disease. However, in high-risk patients with complex coronary artery disease (≥33 SYNTAX/>5 euroSCORE), coronary artery bypass grafting is superior to hybrid coronary revascularization
Familial dilated cardiomyopathy associated with congenital defects in the setting of a novel VCL mutation (Lys815Arg) in conjunction with a known MYPBC3 variant
Idiopathic dilated cardiomyopathy (DCM) is a primary myocardial disorder characterized by ventricular chamber enlargement and systolic dysfunction. Twenty to fifty percent of idiopathic DCM cases are thought to have a genetic cause. Of more than 30 genes known to be associated with DCM, rare variants in the VCL and MYBPC3 genes have been reported in several cases of DCM. In this report, we describe a family with DCM and congenital abnormalities who carry a novel missense mutation in the VCL gene. More severely affected family members also possess a second missense variant in MYBPC3, raising the possibility that this variant may be a disease modifier. Intere - stingly, many of the affected individuals also have congenital defects, including two with bicuspid aortic valve with aortic regurgitation. We discuss the implications of the family history and genetic information on management of at-risk individuals with aortic regurgitation
In-Hospital Outcomes of Transcatheter Aortic Valve Implantation in Patients With End-Stage Renal Disease on Dialysis from a Large National Database.
The outcomes of patients with end-stage renal disease on dialysis (chronic kidney disease stage 5 on dialysis [CKD 5D]) who undergo transcatheter aortic valve implantation (TAVI) are not well described due to the exclusion of this group in randomized trials. We analyzed the National Inpatient Sample database and compared clinical characteristics and in-hospital outcomes for patients with CKD 5D versus those without CKD 5D (nondialysis group) who underwent TAVI in 2011 to 2014 in the United States. The study population included 1,708 patients (4%) with CKD 5D and 40,481 patients (96%) without CKD 5D who underwent TAVI. Patients with CKD 5D were younger (75.3 ± 9.9 vs 81.4 ± 8.4 years,
