myocardial dysfunction is a major complication in cardiac surgery that needs inotropic support. this study evaluates the effect of milrinone on patients with low ventricular ejection fraction undergoing off- pump coronary artery bypass graft (opcab). the present study is designed to evaluate the effect of milrinone on myocardial dysfunction. eighty patients with low ventricular ejection fractio...
OBJECTIVE Whether cardiac ventricles can acutely dilate during septic myocardial dysfunction. DESIGN A prospective echocardiographic study was performed to assess changes of left ventricular dimensions over time in patients with septic shock. SETTINGS A 20-bed surgical intensive care unit of Pitié-Salpêtrière university hospital in Paris. PATIENTS Forty-five patients were studied over the...
After the introduction of endocardial radiofrequency catheter, only two arrhythmias, atrial fibrillation and ischemic ventricular tachycardia require surgical procedures. In this review, we describe recent advancements and problems of surgical treatment for atrial fibrillation. On the basis of multiple-circuit re-entry theory, Cox developed the maze operation with the aim of interrupting the re...
Septal myocardial protection during cardiac surgery for prevention of right ventricular dysfunction.
Postoperative right ventricular (RV) failure is difficult to treat and develops from functional impairment of the underlying free wall and septum. This report describes the vital importance of the ventricular septum in RV structure /function relationships, demonstrates how the helical ventricular myocardial band model defines spatial geometry of the free wall and septum to provide architectural...
purpose: compaison of excyclotorsion induced by horizontal transposition of vertical rectus muscles versus vertical transposition of horizontal rectus muscles in rabbit eyes. methods: in this exprimental study, group 1 underwent full tendon nasal transposition of the superior rectus and full tendon temporal transposition of the inferior rectus (10 adult rabbits); group 2 underwent superior tran...
Takotsubo cardiomyopathy, also known as stress-induced is a temporary left ventricular dysfunction caused by catecholamine surge under severe stress. It's characterized chest pain, non-specific ECG changes, and apical ballooning observed during catheterization. We present case of 59-year-old postmenopausal female with past medical history asthma who arrived at the ED complaining pain following ...
Myxomas comprise 50% of all benign cardiac tumors in adults, with the right atrium as their second most frequent site of origin. Surgical resection is the only effective therapeutic option for patients with these tumors. The association between right atrial myxomas and severe left ventricular systolic dysfunction is extremely rare and makes treatment even more challenging. This was the case for...
BACKGROUND Left ventricular noncompaction is a cardiomyopathy characterized by excessive trabeculation of the left ventricle, progressive myocardial dysfunction, and early mortality. Left ventricular noncompaction has a heterogeneous clinical presentation that includes arrhythmia and sudden cardiac death. METHODS AND RESULTS We retrospectively reviewed all children diagnosed with left ventric...
INTRODUCTION Due to the increase in average life expectancy and the higher incidence of cardiovascular disease with advancing age, more elderly patients present for cardiac surgery nowadays. Advances in pre- and postoperative care mean that more elderly patients can be operated on safely and with a satisfactory outcome. Currently, coronary artery bypass surgery, aortic and mitral valve surgery ...
BACKGROUND Primary repair of Fallot tetralogy has been performed successfully for the last 45 years. It has low surgical mortality (< 5%), with excellent long-term results. However, there are delayed adverse effects: progressive right ventricular dilation and dysfunction, arrhythmia, and sudden death. In our centre, Fallot tetralogy is the most common form of cyanotic congenital heart disease (...
