HCM心室异常诊断：遗传检测与影像学技术如何优化手术规划？

For diagnosing intraventricular abnormalities and planning surgical interventions in HCM, genetic testing remains essential. Additionally, late contrast-enhanced magnetic resonance imaging (MRI) and transesophageal echocardiography with tissue velocity Doppler imaging are invaluable. These techniques provide detailed insights into abnormal intraventricular structures and assess the functional derangement of the myocardium, including diastolic dysfunction in the isolated restrictive phenotype of HCM, as well as the mechanics and amplitude of cardiac contractions (e.g., the twisting/untwisting phenomenon). They also enable calculation of the percentage and degree of myocardial involvement in the fibrous process. Follow-up data obtained from these methods help predict improvements in myocardial relaxation and assess functional outcomes.
