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)
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)
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)
Reoperative coronary artery bypass grafting secondary to saphenous vein graft (SVG) stenosis is a mushrooming problem. The internal thoracic artery graft (ITA) provides superior long-term patency, but its flow is limited and may be inadequate to meet large myocardial demands. To evaluate the efficacy of the ITA as a replacement conduit for a stenotic SVG,(More)
Although it is desirable at coronary reoperation to replace a stenotic vein graft to the left anterior descending coronary artery (LAD) with an internal mammary artery (IMA) graft, previous reports have shown that if the stenotic vein graft is removed, that strategy can be complicated by severe hemodynamic deterioration and increased perioperative(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 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)
