OBJECTIVE The aim of our study was to evaluate the impact of recent clopidrogel use before off-pump coronary artery bypass grafting on the postoperative risk of bleeding. METHODS During the period January 2003 to December 2006, 1104 consecutive patients underwent off-pump coronary artery bypass grafting. Patients were divided into two groups according to(More)
Recognition of the P wave is important for the correct characterization of atrial and ventricular arrhythmias. When the P wave is difficult to identify on standard electrocardiography (SECG), either esophageal electrocardiography (EECG) or intracardiac electrocardiography (IC-ECG), central venous catheter may be used. The feasibility of these methods has(More)
The presence of large lead vegetations poses additional difficulties for explantation because many methods cannot be used due to the potential hazard of embolism. We report two patients with large vegetation on the ventricular lead due to endocarditis and one of them with an atrial septal defect associated. It was applied a combined technique of transvenous(More)
BACKGROUND This was a single-institutional study about total arterial off-pump coronary artery bypass graft surgery (OPCABG) using bilateral internal thoracic arteries in triple-vessel disease. METHODS We retrospectively reviewed the records of 569 multivessel CABG patients (10% female) who underwent total arterial (bilateral internal thoracic arteries)(More)
Osler-Rendu-Weber (hereditary hemorrhagic telangiectasia) disease is an uncommon disease characterized by the presence of abnormal telangiectasias and arteriovenous malformations that cause recurrent episodes of bleeding. We present a patient with Osler-Rendu-Weber disease, with a history of multiple major bleeding events and severe aortic valve stenosis,(More)
This work shows an extension of dual-modifier adaptation methodology for RTO to reduce the infeasibilities. The main idea is to add a PI controller that is activated only when the measurements shows a violation in the constraints. Since the dual problem is solved to estimate the gradients of the process, an additional controller must be considered in order(More)
BACKGROUND Hemorrahage after coronary re-implantation during a Bentall surgery is a rare complication. In case of friable tissue, the use of a felt disc usually solves the problem. The use of resorcinol-formol-glue should be avoided to prevent tissue damage. Extrinsic compression of the coronary arteries has been reported with the use of this surgical glue.(More)
OBJECTIVE The purpose of this study was to evaluate the feasibility and safety of immediate extubation (ultrafast-track anesthesia [UFTA]) in the operating room, and the predictors of when not to attempt it in patients undergoing off-pump coronary artery bypass graft surgery (OPCAB).
