Abstract
AbrtractObjective:To discuss the character of cardiac magnetic resonance and echocardiogram findings of apical hypertrophic cardiomyopathy (AHCM), and evaluate the diagnostic value of CMR and echocardiogram in AHCM.Materials and Methods: Twenty-one patients (male 16, female 5) with AHCM underwent Cardiac Magnetic Resonance, echocardiogram, ECG and coronary angiography. Results:The cardiac magnetic resonance revealed apical hypertrophic in all the patients. Among them, 13 patients were pure form P-AHCM, 1 patient was pure form T-AHCM, 1 patient was mixed form P-AHCM, and 6 patients were mixed form T-AHCM. Magnetic resonance imaging showed “ace of spades” morphology of the left ventricle in all the T-AHCM patients. Four patients underwent myocardial contrast enhancement MR scanning: 3 patients presented LGE, 2 patients presented myocardial ischemia, and 2 patients presented myocardial infarction. Echocardiography provided correct diagnoses in 6/21 patients (28.6%), while in 10 patients echocardiographic results were normal. All of our patients showed electrocardiographic alterations of the ventricular repolarization: 14 patients (67.7%) with LV high voltage. Seventeen patients (80.9%) with giant negative T waves. Sixteen patients (76.2%) with a signiifcant descending ST segment. Four patients had arrhythmia in different degrees.Conclusions: MR has higher sensitivity in diagnosing AHCM than echocardiogram. The ECG is a helpful tool to screen AHCM. To the patients who is suspected of AHCM, cardiac magnetic resonance could make a deifnite diagnosis.关键词
