Catheter ablation of ventricular arrhythmias in left ventricular noncompaction cardiomyopathy
2021, Heart RhythmCitation Excerpt :The study was approved by the human research ethics committee of the centre and was conducted in accordance with the Declaration of Helsinki. LVNC diagnosis was based on the presence of an end-systolic ratio of noncompacted to compacted layers above 2 on echocardiography15,16 and/or an end-diastolic ratio between the noncompacted and the compacted layer >2.3 on cardiac magnetic resonance.15–18 DCM was defined as dilatation (left ventricular [LV] end-diastolic volumes or diameters > 2SD from normal according to nomograms corrected by body surface area and age/sex) and LV or biventricular systolic dysfunction not explained by abnormal loading conditions or coronary artery disease.19
Reference values for left and right ventricular trabeculation and non-compacted myocardium
2015, International Journal of CardiologyCitation Excerpt :Likewise, high rates of 43% of subjects showing a NC/C ratio > 2.3 in at least one segment were reported from an analysis of the MESA cohort [7]. Fazio et al. proposed a higher NC/C cut-off value of 2.5 [18] which still would leave 44 subjects (37.6%) of our study population classified as pathological. Since cardiac diseases were meticulously ruled out, the diagnoses by the NC/C ratio in this population have to be considered as false-positive.
Left ventricular noncompaction: A distinct cardiomyopathy or a trait shared by different cardiac diseases?
2014, Journal of the American College of CardiologyCitation Excerpt :Advanced CMR modalities can provide additional information. For example, high-intensity endocardial T2 signals, subendocardial perfusion defects, and delayed enhancement of the subendocardial layer can add information about function and fibrosis of the affected segments and the possibility of assessing whether abnormalities coincide with noncompacted versus compacted segments (65,66). Advances in imaging are contributing to the ability to distinguish pathologic LVNC from nonpathologic hypertrabeculation.
Characteristics of trabeculated myocardium burden in young and apparently healthy adults
2014, American Journal of CardiologyCitation Excerpt :Trabeculations have been largely overlooked until CMR identified noncompacted myocardium in as much as 91% of volunteers.7 Since that time, new diagnostic criteria of NCC have been proposed.8,13 In our unselected apparently healthy cohort, however, these diagnostic criteria are still remarkably prevalent, being met in 7.5% (using T/D ratio >3 in SA) to 11% of all segments (using T/D ratio >2.5 in any plane).
Comparison of systolic and diastolic criteria for isolated LV noncompaction in CMR
2013, JACC: Cardiovascular ImagingCitation Excerpt :Subsequently, Petersen et al. (11) evaluated 6 patients with LVNC and proposed CMR criteria of EDNCCR >2.3. Fazio et al. (22) extended this research and proposed CMR criteria of EDNCCR >2.5. Following these publications, many centers adopted ED measurements to define the imaging criteria for LVNC.
