SummaryTransthoracic and transoesophageal echocardiography are increasingly used as tools to improve clinical assessment following cardiac surgery. However, most physicians are not trained in echocardiography, and there is no widespread agreement on the feasibility, indications or effect on outcome of transthoracic or transoesophageal echocardiography for patients after cardiac surgery. We performed a systematic review of electronic databases for focused transthoracic and transoesophageal echocardiography after cardiac surgery which revealed 15 full‐text articles. They consistently reported that echocardiography is feasible, whether performed by a novice or expert, and frequently resulted in important changes in diagnosis of cardiac abnormalities and their management. However, most were observational studies and there were no well‐designed trials investigating the impact of echocardiography on outcome. We conclude that both transthoracic and transoesophageal echocardiography are useful following cardiac surgery.
A considerable number of patients who undergo cardiac surgery have a variety of comorbid conditions that includes diastolic dysfunction. Abnormalities of diastolic function may lead to diastolic heart failure that can complicate their postoperative course. This form of failure occurs more commonly in patients with hypertensive or valvular heart disease, diabetes mellitus, myocardial ischaemia, as well as in hypertrophic or restrictive cardiomyopathy, and is more prevalent in the elderly. In spite of it being a common cause of heart failure it remains underreported in the postoperative heart. We reviewed relevant literature analysing the different therapeutic approaches and formulated a management plan for diastolic heart failure in the postoperative heart in the intensive care environment based on the most current understanding of this form of cardiac failure.
Substituição da valva mitral com preservação do aparato completo da valvaMitral valve replacement with the preservation of the entire valve apparatus Abstract Objective: The papillary muscles and the chordae tendineae of both mitral leaflets contribute to the preservation of the left ventricular function. Most surgeons, however, routinely excise the anterior mitral leaflet.Methods: In a group of nine patients, six of them underwent mitral valve replacement alone and three underwent both aortic and mitral valve replacements, all the mitral apparatus was preserved. All of these patients had mechanical valves using CarboMedics cardiac prosthesis (CarboMedics, Inc. Austin, Texas).Results: There was no mortality. Postoperative echocardiographic assessment revealed maintained left ventricular function with no interference with the prosthetic leaflet mobility and no left ventricular outflow tract gradient.Conclusion: We believe that in most patients with longstanding mitral valve regurgitation, thinned out papillary muscles and elongated chordae tendineae that are not amenable to repair, valve replacement with the preservation of the entire native valve is possible and should be encouraged. This is especially valuable for those with depressed left ventricular function, who might otherwise suffer from left ventricular dysfunction in the long-term if the entire mitral valve apparatus were to be excised.Descriptors: Mitral valve, surgery. Mitral valve insufficiency, surgery. Heart valve prosthesis implantation, methods.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
