IMAGING FEATURES OF ISOLATED LEFT VENTRICULAR NON-COMPACTION: A CARDIAC CT STUDY

Аннотация

INTRODUCTION Isolated left ventricular non-compaction (ILVNC) is Accurate diagnosis of ILVNC is crucial for effective a rare cardiomyopathy characterized by the management and prognosis, as it can significantly presence of excessive trabeculations and deep impact therapeutic decisions and patient intertrabecular recesses within the left ventricular outcomes. Traditionally, echocardiography has myocardium. This condition is believed to result been the primary imaging modality used for the from an arrest in the normal compaction process of diagnosis of ILVNC. However, cardiac computed the developing myocardium during tomography (CT) has emerged as a valuable embryogenesis. The clinical presentation of ILVNC complementary tool, offering superior spatial is highly variable, ranging from asymptomatic resolution and detailed anatomical assessment. individuals to those with heart failure, Cardiac CT allows for precise visualization of arrhythmias, thromboembolic events, and sudden myocardial trabeculations and the non-compacted cardiac death. to compacted myocardium ratio (NC/C ratio), https://www.theamericanjournals.com/index.php/tajmspr 1 THE USA JOURNALS THE AMERICAN JOURNAL OF MEDICAL SCIENCES AND PHARMACEUTICAL RESEARCH (ISSN – 2689-1026) VOLUME 06 ISSUE08 enhancing the diagnostic accuracy for ILVNC.
