Factors associated to hypoxemia in patients undergoing coronary artery bypass grafting

INTRODUCTION: Hypoxemia is a frequent pulmonary complication in the postoperative coronary artery bypass graft. Detection of factors associated with their occurrence may indicate patients at risk for this complication, which allows tracing specific therapeutic and consequently reduce morbidity and mortality. OBJECTIVE: To identify related factors to hypoxemia occurrence in...

Extracorporeal membrane oxygenation as a support for TGA/IVS with low cardiac output syndrome and pulmonary hemorrhage

A 15-day-old neonate with complete transposition of the great arteries/intact ventricular septum was admitted with life-threatening hypoxemia and heart arrest. After successful resuscitation, heart beat recovered but blood lactate began to arise and maintained above 15 mmol/L 6 hours later. Emergency arterial switch operation was done at 20 hours after resuscitation. Planned...

Clinical and ultramicroscopic myocardial randomized study of beating versus arrested heart for mitral surgery

INTRODUCTION: Beating heart surgery on normothermic bypass simulates physiologic cardiac status. OBJECTIVES: This study compared clinical and transmission electron microscopic aspects of myocardial protection during mitral valve replacement using warm retrograde perfusion in empty beating versus arrested heart with cold blood anterograde cardioplegia. METHODS: Randomized study to...

Stent aórtico pulsátil: uma nova alternativa na assistência ventricular crônica

OBJECTIVE: Heart failure is currently one of the most common hospitalization causes. Several chronic circulatory assist devices have been tested and are highly complex. The objective is the description of a pulsatile endoprosthesis capable of applying a chronic pulse within the descending aorta, similar to that produced by intra-aortic balloon. METHODS: Pulsatile stents composed...

Mediastinitis: mortality rate comparing single-stage surgical approach and preconditioning of wound

OBJECTIVE: This study aims to compare hospital mortality rate of surgical debridement followed by primary wound closure versus surgical debridement with closure after preconditioning of the wound. METHODS: A historical cohort of 43 patients with postoperative mediastinitis type III and IV between 2000 and 2008. The diagnosis of mediastinitis was based on physical examination and...

Doppler echocardiographic criteria in patency assessment of composite grafts from left internal thoracic artery

OBJECTIVES: The purpose of our study was to establish, with an entirely noninvasive method, transthoracic Doppler echocardiography, criteria for patency of composite left internal thoracic artery grafts when placed on the left anterior descending artery and other branches of the left coronary system. METHODS: The control group comprised 20 patients with single graft and 20...

Correção endovascular de dissecção de aorta ascendente

Woman, 84 years-old, with Stanford type A thoracic aortic dissection committing aortic arch and descending aorta. Proposed and accepted endovascular treatment according to the severity of the clinical picture. Common femoral artery dissection bilaterally was done. Aortography confirmed the exclusion of the false lumen and patency of the coronary ostia.

Analysis of left ventricular function in patients with heart failure undergoing cardiac resynchronization

BACKGROUND: The gold standard surgical treatment for heart failure is cardiac transplantation, however, due to difficulties of this treatment, other surgical proposals have been reported, including the implantation of cardiac resynchronizer. OBJECTIVE: To analyze the left ventricular function by echocardiography in patients with advanced heart failure with interventricular...

Beneficial effects of hyperosmotic perfusion in the myocardium after ischemia/reperfusion injury in isolated rat hearts

OBJECTIVE: A simple method to reduce the ischemia/reperfusion injury that can accompany cardiac surgery would have great clinical value. This study was to investigate the effect of hyperosmotic perfusion on ischemia/reperfusion injury in isolated perfused rat hearts. METHOD: Forty male Sprague-Dawley rats were randomly divided either to have their isolated hearts perfused with...

Correlação entre a qualidade de vida, classe funcional e idade em portadores de marca-passo cardíaco

OBJECTIVE: To evaluate whether there is a correlation between quality of life and functional class in early heart pacemaker in patients, and its relationship with age. METHODS: 107 patients of both sexes (49.5% female/50.5% male) were investigated, average implant time of 6.36 months (±2.99), and average age of 69.3 years (±12.6). To assess the FC, a scale suggested by Goldman...

Correção da ruptura de cordas tendíneas na insuficiência mitral degenerativa pelo emprego de cordas padronizadas de pericárdio bovino

OBJECTIVE: To evaluate clinically and by Doppler Echocardiography 22 patients submitted to mitral valve repair after valvular regurgitation using standardized bovine pericardium chordae. METHODS: The patients had degenerative mitral regurgitation. Fourteen (63.6%) patients were male and the age ranged from 19 to 76 years (mean 56.8 ± 13.8 years). The strings of bovine pericardium...

Risk factors for pre, intra, and postoperative hospital mortality in patients undergoing aortic surgery

OBJECTIVES: The primary objective was to identify predictors of hospital mortality in patients undergoing aortic surgery.
