19 sie 2019 · Papillary muscle rupture is a major complication of acute myocardial infarction that results in mitral regurgitation and associated with high mortality rates. The most common papillary neoplasm is metastasis, but primary benign and malignant neoplasms can also be seen.
29 kwi 2015 · In this study, we characterize the clinical, electrocardiographic, and electrophysiological features of left Pap VAs in patients undergoing catheter ablation and compare these features to those of left fascicular and focal mitral annular VAs.
Scar volumes agree well, with peri-infarct volumes correlating less well. 3D LGE may be superior in visualization of papillary muscle scar. Higher spatial resolution 3D LGE provides sharper images and higher SNR, but less myocardial nulling.
This article is intended to describe quality control procedures, factors affecting image quality, assessment of myocardial scar, and potential pitfalls and artefacts causing focal hyperintensities that mimic myocardial scar in delayed enhancement imaging.
18 paź 2012 · The detection of papillary muscle infarction (PMI) may be difficult due to the bright blood signal. The aim of our study was to evaluate the incremental value of LGE CMR imaging using an inversion recovery (IR)-GRE with a short-inversion time (TI) over standard LGE imaging in identifying PMI. Methods and results.
22 lip 2021 · Although mostly desired for improved detection of subendocardial scar areas, dark-blood LGE methods may also be beneficial for visualizing scar patterns in papillary muscles and thin-walled structures, such as the atria and RV.
The papillary muscles (PMs) are a source of ventricular ar-rhythmias (VAs) in both structurally normal and abnormal hearts. Presentation includes isolated premature ventricular contractions (PVCs), nonsustained ventricular tachycardia (VT), and sustained recurrent VT.
