Clinical implications of midventricular obstruction in patients with hypertrophic cardiomyopathy.
OBJECTIVES We investigated the prevalence, clinical characteristics, and prognosis of hypertrophic cardiomyopathy (HCM) patients with midventricular obstruction (MVO). BACKGROUND Previous descriptions of patients with MVO have been confined to case reports or small patient series, and this subgroup of HCM patients has therefore remained underrecognized. METHODS The study population included...
متن کاملSeptal myectomy for obstructive hypertrophic cardiomyopathy.
Septal myectomy effectively relieves left ventricular outflow tract obstruction (LVOTO) and cardiac symptoms in both adults and children with obstructive hypertrophic cardiomyopathy (HCM). Abnormal attachments of the papillary muscles and chordae and other cardiac lesions can be repaired at the same time. Early mortality for isolated septal myectomy in both children and adults is low (0% to 2.5...
متن کاملExtended myectomy in the treatment of patients with hypertrophic obstructive cardiomyopathy
INTRODUCTION Partial resection of the septal muscle is a well-established and effective method of surgical treatment for patients with hypertrophic obstructive cardiomyopathy (HOCM). The procedure is characterized by a low operative mortality rate and long-term clinical improvement that has been confirmed in numerous publications. Mitral insufficiency in patients with HOCM is mostly functional ...
متن کاملPressure Tracings in Hypertrophic Cardiomyopathy With Dynamic Midventricular Obstruction
A 50-year-old man was admitted for evaluation of syncope. Clinically, he had an irregular pulse and an ejection systolic murmur loudest at the left sternal border. Transthoracic echocardiography revealed hypertrophic cardiomyopathy (HCM) with midventricular obstruction and apical aneurysm with maximum pressure gradient greater than 74 mm Hg. Coronary angiogram showed normal coronary arteries. L...
متن کاملSubaortic and midventricular obstructive hypertrophic cardiomyopathy with extreme segmental hypertrophy
BACKGROUND Subaortic and midventricular hypertrophic cardiomyopathy in a patient with extreme segmental hypertrophy exceeding the usual maximum wall thickness reported in the literature is a rare phenomenon. CASE PRESENTATION A 19-year-old man with recently diagnosed hypertrophic cardiomyopathy (HCM) was referred for sudden death risk assessment. The patient had mild exertional dyspnea (New Y...
