Abstract：
BACKGROUND: There has been an increase in the reporting of cases of left ventricular noncompaction (LVNC) cardiomyopathy in medical literature due to advances in medical imaging. Patients with LVNC may be asymptomatic or may present with arrhythmias, heart failure, thromboembolism or sudden death. LVNC is typically diagnosed by echocardiography, although there are higher-resolution cardiac imaging techniques such as cardiac magnetic resonance imaging (MRI) to make the diagnosis. The objective of the study is to report on a series of 9 cases of LVNC cardiomyopathy seen at the University College Hospital, Ibadan. Cases of LVNC seen between September 1, 2015 and July 31, 2022 in our echocardiography service is being reported.
RESULTS: There were a total of 6 men and 3 women. Mean age at presentation was 52.89 ± 15.02 years. The most common mode of presentation was heart failure (6 patients). Hypertension was the most common comorbidity (6 patients). Three patients had an ejection fraction of less than 40% and the mean ratio of noncompacted to compacted segment at end-systole was 2.80 ± 0.48. The most common areas of trabecular localization were the LV lateral wall and the apex. Beta blockers were highly useful in the management of the patients.
CONCLUSIONS: LVNC cardiomyopathy is not uncommon in our environment and a high index of suspicion is often required.

摘要：
背景：由于医学影像学的进步，医学文献中左心室致密化不全（LVNC）心肌病的病例报告有所增加。LVNC患者可能无症状或存在心律失常，心力衰竭,血栓栓塞或猝死。LVNC通常通过超声心动图诊断，尽管有更高分辨率的心脏成像技术，如心脏磁共振成像（MRI）来做出诊断。该研究的目的是报告在大学学院医院看到的一系列9例LVNC心肌病，伊巴丹.据报道，我们的超声心动图服务于2015年9月1日至2022年7月31日期间发现的LVNC病例。
结果：共有6名男性和3名女性。就诊时的平均年龄为52.89±15.02岁。最常见的表现模式是心力衰竭（6例）。高血压是最常见的合并症（6例）。3例患者的射血分数小于40％，收缩末期未压缩段与压缩段的平均比率为2.80±0.48。小梁定位的最常见区域是LV侧壁和顶点。β受体阻滞剂在患者的管理中非常有用。
结论：LVNC心肌病在我们的环境中并不少见，通常需要高度怀疑。
