RESUMEN
Introducción:
Se presentan los resultados inmediatos y a 6 años de la cirugía coronaria sin circulación extra corpórea (CEC) en pacientes portadores de lesión de tres vasos y/o del tronco coronario izquierdo (TCI). Métodos yResultados:
Se analiza una cohorte histórica de pacientes con lesión de tres vasos y/o TCI a quienes se realizó cirugía coronaria sin CEC entre junio 2005 y diciembre 2008 (N=100). Corresponden a 81 hombres, edad 61,3 +/- 7,9 años. 20 pacientes tenían lesión del TCI. La fracción de eyección del ventrículo izquierdo fue <30 por ciento en 6, 30 - 50 por ciento en 32 y >50 por ciento en 62 pacientes. El Euro SCORE promedio aditivo era 2,83 y el logístico 3,05. Todas las revascularizaciones se consideraron completas. Se realizaron 3,07 puentes/paciente. Hubo 5 conversiones a cirugía con CEC. Hubo complicaciones postoperatorias en 24 pacientes (3 AVE, 2 IAM, 3 insuficiencias renales agudas, 5 reoperaciones, 1 mediastinitis) y fallecieron 2. El seguimiento promedio fue 72,3 meses (rango 54 - 96). En forma alejada fallecieron 14 pacientes (5 de causa cardiovascular). Hubo 3 IAM; 5 AVE y 7 reintervenciones.Conclusión:
En esta serie de pacientes con lesión de TCI y/o 3 vasos, la cirugía coronaria sin CEC no tuvo ventajas respecto a la cirugía con CEC.ABSTRACT
Aim:
To present early and long term results of Off Pump Coronary artery surgery in patients with three vessel or Main Left Disease. Methods andResults:
100 patients, mean age 61,3 +/- 7,9 years, 81 percent males, with three vessel or main left disease were submitted to off-pump coronary artery bypass between June 2005 and December 2008. Twenty patients had main left disease. Left ventricular ejection fraction was <30 percent in 6 patients, 30-50 percent in 32 and >50 percent in 62. Mean active and logistic Euro scores were 2.83 and 3.05, respectively. Patients were followed up to June 2013. All interventions were considered to have achieved complete revascularization. A mean of 3.07 bypasses were implanted. Five patients had to be converted to open heart surgery. 24 patients had post-operative complications (CVA in 3, AMI in 2, acute renal failure in 3 and mediastinitis in 1 patient. Operative mortality was 2 percent and 5 patients required reoperation. During a period of 72.3 months of follow-up (range 54-96) 14 patients died (5 from cardiovascular causes). There were 3 patients developing AMI, 5 suffered a CVA and 7 required re-revascularization. The overall results described were not different from those observed in similar patients undergoing open heart surgery at our institution.Conclusion:
Off-Pump coronary artery bypass had no advantages over on pump surgery in patients with 3 vessel and/or main left disease at our institution.
