Left Ventricular Papillary Muscles
The left ventricular papillary muscles appear to be the last portions of the heart to be perfused by coronary arterial blood. As a consequence they are sensitive anatomic markers of myocardial ischemia. Foci of necrosis or fibrosis therefore are commonly seen in these structures, particularly the posteromedial papillary muscle, which has a poorer blood supply than does the anterolateral muscle....
متن کامل[Left ventricular papillary fibroelastoma].
We evaluated the case of a patient with Papillary Fibroelastoma (PFE) that presented embolization to the upper right limb. The patient was submitted to percutaneous embolectomy, with fragment removal. The diagnosis was confirmed by transthoracic echocardiogram and anatomopathological analysis of the fragment. The patient chose to undergo the conservative clinical treatment and the follow-up has...
متن کاملFascicular Ventricular Tachycardia Originating From Papillary Muscles
Verapamil-sensitive left fascicular ventricular tachycardia (FVT) has been shown to be a reentrant mechanism using the Purkinje network as a part of its reentrant circuit. Our understanding of this arrhythmia has been extensively developed over the past 2 decades. Radiofrequency catheter ablation is often an effective therapy for treating these arrhythmias. However, 8% to 20% of patients may de...
متن کاملreverse left ventricular apical rotation in dilated cardiomyopathy
conclusions these findings emphasize the potential clinical benefits of therapeutic procedures such as cardiac resynchronization therapy (crt) or apex-sparing volume-reduction surgery in dcm. a better definition of the role and implications of reverse apical torsion in dcm and its importance and effectiveness in making therapeutic decisions like crt implantation requires further studies. case p...
متن کاملTension developed by papillary muscles from hypertrophied rat hearts.
TO DETERMINE whether, in certain aspects, hypertrophied heart muscle behaves differently from normal heart muscle simple observations were performed. Papillary muscle strips from the left ventricle of rats, the hearts of which had been caused to hypertrophy, were compared with papillary strips from normal rat hearts by measuring tension developed at various weights in a perfused isolated muscle...
