The study was conducted to evaluate the surgical results in patients with hypertrophic obstructive cardiomyopathy (HOCM) who underwent either classic Morrow septal myectomy or modified procedure.The modified Morrow septal myectomy has gained interest as a new treatment for patients with drug-refractory symptoms of HOCM; however, its benefits in comparison to the classic procedure are unknown.In...

OBJECTIVES We examined the echocardiographic characteristics of highly trained American football players. BACKGROUND Intense physical training is associated with morphologic and physiologic cardiac changes often referred to as the "athlete's heart." Echocardiographic features peculiar to elite football players have not been described. METHODS We studied cardiac morphology and function as as...

with a small ventricular communication, to a large ventricular septal defect dominating the picture with mild obstruction. When the pulmonary stenosis is mild, whether the ventricular septal defect is small or large, a left-to-right shunt is always present, giving the clinical picture of a ventricular septal defect. On the other hand, if the stenosis is severe and the ventricular septal defect ...

(A) Before the procedure, large residual ventricular septal shunts could be seen between the occluder and the peak of apex (Online Video 1). (B) After the procedure, the shunts decreased significantly (Online Video 2). LV 1⁄4 left ventricle; RV 1⁄4 right ventricle. A 58-year-old man with exertional dyspnea (New York Heart Association class II) was admitted to our hospital. He suffered from acut...

BACKGROUND Thalassemia intermedia is a variety of beta thalassemia which shows clinical symptoms somewhere between asymptomatic carriers and thalassemia major. Cardiac dysfunctions due to chronic anemia and hemosiderosis are the major causes of death in these patients. The purpose of this study is to evaluate cardiac function in these patients by echocardiography. MATERIALS AND METHODS This c...

Objective—To determine preoperatively, by analysing asynchronous left ventricular wall motion, whether to approach through the right ventricle or the left ventricle when carrying out catheter ablation of the accessory pathway in WolVParkinson-White syndrome, especially in patients with the pathway located on the septum. Methods—73 patients with manifest WolV-Parkinson-White syndrome who underwe...

I n patients with hypertrophic cardiomyopathy (HCM), the low positive predictive accuracy of the previously recognised risk factor for sudden death—that is, non-sustained ventricular tachycardia, syncope, abnormal blood pressure response to exercise, family history of sudden death, and massive left ventricular (LV) hypertrophy—is a major limitation. Patients with a combination of two or more su...

Ultrasonic backscatter of myocardial walls is directly related to the morphometrically evaluated collagen content in humans. The integrated backscatter is also increased in hypertrophic cardiomyopathy, whereas it gives normal values in the physiological hypertrophy of elite athletes. We assessed the quantitatively evaluated myocardial reflectivity in 46 mild to moderate, clinically uncomplicate...
