Miniesternotomía para cirugía valvular aórtica: Experiencia inicial en un centro cardiovascular en Chile

Background: Aortic valve surgery can be performed through a reduced mid sternotomy with excellent long term results. Aim: To report the initial results obtained with this technique. Patients and methods: Descríptive study of 20 patients aged 48±11 years, subjected to valve replacement surgery for ao...

Aim: To report the initial results obtained with this technique. Patients and methods: Descríptive study of 20 patients aged 48±11 years, subjected to valve replacement surgery for aortic valve disease between 2004 and 2007. Arterial and venous cannulation were performed with the usual method and extracorporeal circulation was performed with a mean perfusión of 4.5 L/min. Hypothermia and cardioplegia were performed infusing the hematíe cardioplegic solution at 4°C in the aortic root or coronary ostia. Results: Sixteen patients were in functional class (FC) III. Fourteen patients had aortic insufficieney and six had predominant stenosis. There was no operative mortality One patient had a left hemothorax and was reoperated. AU patients were discharged between 4 and 6 days after surgery. Mean follow up was 21 ± 4 months. AU patients are in FC I and free from cardiac events. Echocardiographic assessment was done in 16 patients, showing a good motility of valve disks. Actuarial survival probability was 100% and probability of freedom from cardiac events was 100% at 42 months of follow up. Conclusions: Ministernotomy is an excellent approach for aortic valve surgery providing good visualization ofthe ascending aorta, simplifying the surgical technique.info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.136 n.9 20082008-09-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872008000900008es10.4067/S0034-98872008000900008
