World J Clin Cases 2025; 13:101272. [DOI: 10.12998/wjcc.v13.i15.101272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2024] [Revised: 11/03/2024] [Accepted: 01/07/2025] [Indexed: 01/21/2025] Open
Abstract
BACKGROUND Hypertrophic cardiomyopathy (HCM) is one of the most prevalent inherited myocardial disorders and is characterized by considerable genetic and phenotypic heterogeneity. A subset of patients with HCM progress to a dilated phase of HCM (DPHCM), which is associated with a poor prognosis; however, the underlying pathogenesis remains inadequately understood.
CASE SUMMARY In this study, we present a case involving a pedigree with familial DPHCM and conduct a retrospective review of patients with DPHCM with identified gene mutations. Through panel sequencing targeting the coding regions of 312 genes associated with inherited cardiomyopathy, a heterozygous missense mutation (c.746G>A, p.Arg249Glu) in the MYH7 gene was identified in the proband (III-5). Sanger sequencing subsequently confirmed this pathogenic mutation in three additional family members (II-4, III-4, and IV-3). A total of 26 well-documented patients with DPHCM were identified in the literature. Patients with DPHCM are commonly middle-aged and male. The mean age of patients with DPHCM was 53.43 ± 12.79 years. Heart failure, dyspnoea, and atrial fibrillation were the most prevalent symptoms observed, accompanied by an average left ventricular end-diastolic size of 58.62 mm.
CONCLUSION Our findings corroborate the pathogenicity of the MYH7 (c.746G>A, p.Arg249Glu) mutation for DPHCM and suggest that the Arg249Gln mutation may be responsible for high mortality.

The Value of Contrast-Enhanced Ultrasound (CEUS) in the Detection of Perfusion Disturbances in Abdominal Wall Hernias Compared with Surgical and Histological Assessment. Diagnostics (Basel) 2022; 12:370. [PMID: 35204462 PMCID: PMC8871308 DOI: 10.3390/diagnostics12020370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 01/24/2022] [Accepted: 01/27/2022] [Indexed: 12/04/2022] Open
Abstract
Purpose: This study aimed to evaluate the value of contrast-enhanced ultrasound (CEUS) in the evaluation of perfusion disturbance in irreducible abdominal wall hernias (AWHs). Methods: From 2006 to 2018, 50 patients with an irreducible AWH were examined using B-mode ultrasound (B-US) and CEUS. The ultrasound findings were correlated with subsequent surgical and histological results. The presence of non-enhanced areas (NEAs) in hernia contents on CEUS and the presence of non-perfused areas (NPAs) on surgical and histological evaluation were analyzed retrospectively. Results: On CEUS, 13/50 hernia contents (26.0%) revealed NEAs during complete CEUS examination and 37/50 (74.0%) revealed no NEAs during CEUS examination. On surgical and histological evaluation, NPAs in hernia contents were identified in 11/13 cases (93.3%) with NEAs on CEUS. CEUS was found to have a sensitivity of 100.0%, a specificity of 94.9%, a positive predictive value of 84.6%, and a negative predictive value of 100.0% for the identification of perfusion disturbance in AWHs. Conclusions: The findings of this study demonstrate that using CEUS as an imaging method may be helpful for evaluating the perfusion of hernia contents in incarcerated AWHs. On CEUS, the presence of NEAs may suggest perfusion disturbance in hernia contents.
