Abstract Background The timing for heart surgery following cerebral embolization after cardiac valve vegetation is vital to postoperative recovery being uneventful, additionally Covid-19 may negatively affect the outcome. Minimally invasive methods and upgraded surgical instruments maximize benefits of also in complex revision cases with substantial perioperative risk. Case presentation A 68 y....
INTRODUCTION The right anterolateral thoracotomy is an alternative technique for surgical approach of mitral valve. In these cases, femoral-femoral bypass still has been used, rising occurrence of complications related to femoral cannulation. OBJECTIVE Describe the technique and results of mitral valve treatment by right anterolateral thoracotomy using aortic cannulation for cardiac pulmonary...
a 47 year-old female died after mitral valve replacement. post-cardiopulmonary bypass right ventricle was not able to pump despite good left ventricular contractility. at microscopic examination, diffuse right ventricular fatty infiltration was found. we found no previous report of this pathology in patients with mitral stenosis
Criteria for selection of patients with aortic valve disease for cardiac catheterization are described, based on a study of 81 cases. Children with aortic stenosis warrant catheterization at the time when the clinical diagnosis is made, but in adults this examination may be deferred until symptoms appear or left ventricular hypertrophy is recognized. In patients with pure aortic insufficiency c...
We developed and validated a mitral valve orifice method for Doppler cardiac output determination. In 15 open-chest dogs, cardiac output was controlled and measured by a roller pump interposed between the right atrium and pulmonary artery as a right-heart bypass. Left heart flows were measured in the open-chest dog model by Doppler measurements at the mitral valve orifice and compared not only ...
BACKGROUND Reoperative cardiac valve surgery via sternotomy is associated with a substantial morbidity and mortality. This study evaluated the right anterolateral thoracotomy for high-risk patients undergoing mitral and tricuspid valve redo procedures. METHODS Out of a series of 173 patients undergoing redo cardiac valve surgery, 24 patients were reoperative via the right anterolateral thorac...
BACKGROUND The purpose of this study was to investigate the genesis of the Austin Flint murmur using Doppler and echocardiographic imaging. METHODS AND RESULTS A total of 51 patients having significant aortic insufficiency and an anatomically normal mitral valve were evaluated. They were divided into two groups; 30 patients had an audible Austin Flint murmur (AFM+) and 21 did not (AFM-). All ...
OBJECTIVE To compare the early and late outcomes of off-pump coronary artery bypass grafting and coronary artery bypass graft + mitral valve repair in elderly patients with moderate chronic ischemic mitral regurgitation. METHODS One hundred and fifty elderly (age > 70 years) patients with moderate chronic ischemic mitral regurgitation who underwent off-pump coronary artery bypass grafting (n=...
BACKGROUND Re-do mitral valve procedures performed through median sternotomy carry substantial mortality and morbidity. To avoid complications of sternal re-entry and to provide adequate mitral valve exposure, antero-lateral thoracotomy has been suggested by some authors. METHODS From October 1997 to January 2007, 677 mitral valve operations have been performed in our centre using port-access...
Paravalvular leak (PVL) occurs in up to 12.5% of mitral valve replacements (MVRs) and sometimes recurs. Although various techniques to repair such leaks have been described, surgical intervention for patients undergoing multiple repeat surgery poses a formidable challenge. For the purposes of good exposure and durable repair of mitral PVL, we describe a double closure technique with pledgeted s...
