Challenges and diagnosis of isolated left ventricular non-compaction: A case series of 4 patients with echocardiographic diagnosis of possible ILVNC

Abstract

Volume 16 Number 1 FIGURE 2: Apical 4 chamber view of Case 3, showing trabeculations in the apex of the left ventricular wall. TABLE I: Summary of patients' demographic information, and clinical and echocardiographic features. Age (years) Gender Ethnicity Clinical and echocardiographic features Case 1 59 Male African Long-standing hypertension. Presented with peripheral oedema, and class II NYHA dyspnoea. Echocardiography showed LV non-compaction with prominent trabeculae in the LV apex. LVEF 24%, LVEDD 7.3cm, LVESD 6.3cm Case 2 16 Male African Prior diagnosis of anthracycline-induced cardiomyopathy. Asymptomatic. LVEF 30% with global hypokinesia and severe non-compaction of LV free wall and apex. LVEDD 6.3cm, LVESD 5.2cm. Case 3 37 Female African Presented with symptoms of heart failure, 2 months post-partum, and diagnosed with post-partum cardiomyopathy. LVEF 18% with trabeculation of LV apex and free wall. LVEDD 5.6cm, LVESD 5.2cm Case 4 48 Male African History of alcohol abuse. Presented with chest pain and palpitations ,with an "irregular pulse". Echocardiography showed severe trabeculations from mid-to-apical region. "Smoke" * observed in LV; LVEF 24%.

Differentiation of patients with two-dimensional echocardiography false positive non-compaction of ventricular myocardium by contrast echocardiography

“…Transthoracic echocardiography is difficult to diagnose especially in suspected patients with NVM. Combined with contrast echocardiography, the endocardium can be clearly displayed and the diagnostic rate of NVM can be improved (Lufundo et al, 2019;Arenas et al, 2018;Friedberg, 2018). In this study, LVO was performed in suspected patients with NVM to be diagnosed by TTE.…”
