The clinical and haemodynamic findings in a patient with hypertrophic obstructive cardiomyopathy and severe left ventricular outflow obstruction are presented. Treatment with an increasing dose of orally administered practolol up to a maximum of 1200 mg a day, resulted in symptomatic improvement, and abolition of the resting gradient when the patient was recatheterized six months later.

OBJECTIVES The purpose of this study was to determine the effect of accessory or anomalous atrioventricular valvar apparatus on relief of outflow tract obstruction. BACKGROUND Outflow tract obstruction due to accessory tissue or anomalous attachments of the atrioventricular valvar apparatus is an unusual but well-recognized problem. In addition to obstruction, anomalous attachments of the atr...

Primary cardiac tumors in infancy and childhood are rare and usually benign. Fibroma is the second most common bening cardiac tumor after rhabdomyoma. Surgery is required when fibromas cause ventricular outflow tract obstruction, ventricular dysfunction and life-threatening arrhythmia. This case report describes a 9-year-old asymptomatic male presenting with a giant left ventricular cardiac fib...

Most cases of cardiac metastasis from renal cell carcinoma (RCC) involve the vena cava or right atrium. Left ventricular metastases from RCC without involving the vena cava or right atrium are extremely rare. Herein we report a case of RCC with left ventricular metastasis causing left ventricular outflow obstruction (LVOT).

INTRODUCTION AND OBJECTIVES Left ventricle outflow tract obstructions in transposition of the great arteries are frequent. We report the correlations between two-dimensional echocardiographic and autopsy findings to draw attention to the usefulness of this diagnostic method in the preoperative evaluation of these anomalies. MATERIAL AND METHODS Of 73 hearts with transposition of great arterie...

Fifty patients with hypertrophic cardiomyopathy underwent invasive study of coronary and myocardial hemodynamics in the basal state and during the stress of pacing. The 23 patients with basal obstruction (average left ventricular outflow gradient, 77 +/- 33 mm Hg; left ventricular systolic pressure, 196 +/- 33 mm Hg, mean +/- 1 SD) had significantly lower coronary resistance (0.85 +/- 0.18 vers...

Obstructive Hypertrophic Cardiomyopathy: Pathogenesis of the Obstruction In most patients, the hypertrophy develops initially in the septum and extends to the free walls, often giving a picture of concentric hypertrophy. In '25% of patients with familial hypertrophic cardiomyopathy (FHCM), asymmetrical septal hypertrophy leads to a highly variable pressure gradient between the apical left ventr...

Pulmonary valve replacement is required after tetralogy of Fallot or surgery performed for relief right ventricular outflow obstruction. Interventional methods are more preferable patient comfort in medical practice. Here we introduce a 14-year-old male who developed complications migration and thrombosis intervention pulmonary replacement, was successfully treated with second operation.
