- ItemFactores determinantes en la aparición de fibrilación auricular post-cirugía de revascularización miocárdica. Un estudio prospectivo(2007) Baeza Vergara, Ricardo Gabriel; Garayar Pulgar, Bernardita; Morán Velásquez, Sergio; Zalaquett Sepúlveda, Ricardo; Irarrázaval Llona, Manuel José; Becker Rencoret, Pedro Antonio; Viviani García, Paola; Ferrada, Marcela; Corbalán Herreros, RamónBackground: Atrial fibrillation (AF) is a relevant complication after coronary artery bypass grafting (CABG). However there is controversy regarding possible contributing factors. Aim: To study the incidence of AF, its risk factors and its repercussion on hospital stay and charges, in patients undergoing CABG. Material and methods: We prospectively collected information from all patients undergoing CABG in our institution, including demographic, surgical and laboratory variables. Exclusion criteria were chronic AF, recent onset AF and patients who needed additional surgical procedures. The primary endpoint was the incidence of AF during the hospital stay. Secondary endpoints were hospital length of stay and hospital charges. Results: We included 250 patients aged 62±9 years (199 males) in the analysis. Incidence of AF was 22% (54 patients). Multivariable analysis showed that age (Odds Ratio (OR) =1.10), previous CABG (OR =9.39), previous use of ACE inhibitors (OR =3.28) and aortic clamp >57 minutes (OR =3.97) were significantly associated with an increased risk of postoperative AF. Previous use of beta-blockers was associated with risk reduction (OR =0.43). Patients who developed AF had a longer hospital stay (p <0.001) and higher hospital charges (p =0.003). Conclusion: AF is a frequent complication in patients undergoing CABG. Risk factors are age, time of aortic clamp, previous CABG and ACE inhibitors. Beta-blockers may prevent its occurrence. Furthermore, AF has a negative impact on both hospital stay and hospital charges

- ItemTratamiento endovascular del trauma de aorta descendente(2005) Mertens Martin, Renato; Valdés Echeñique, José Francisco; Kramer, Albrecht; Bergoeing Reid, Michel Paul; Zalaquett Sepúlveda, Ricardo; Baeza Prieto, Cristian Rafael; Moran Velásquez, Sergio; Irarrázaval Llona, Manuel José; Becker Rencoret, Pedro Antonio; Huete Garín, Álvaro; Vergara G., Jeannette; Valdebenito G., MagalyBackground: Mortality of traumatic aortic lesions is over 80%. A group of those who survive, develop a chronic pseudo aneurism, usually asymptomatic, that is detected during imaging studies. Since conventional surgical treatment of traumatic aortic lesions has a great mortality, endovascular treatment has been used as an alternative treatment in the last decade. Aim: To report our experience with endovascular treatment of traumatic aortic lesions. Patients and methods: Report of seven patients aged 22 to 65 years, with traumatic aortic lesions. Under general anesthesia an endovascular prosthesis was inserted through the femoral artery. Results: No complications were observed in the postoperative period, and after a follow up ranging from 4 to 40 months, no endoleaks or other complications have been detected. Conclusions: Endovascular treatment of traumatic aortic lesions has good immediate and midterm results.
