Malignant arrhythmia with benign tumour: fibrolipoma of the left ventricle.

We report a case of young male referred for evaluation of recent onset recurrent syncope. Inhospital electrocardiogram revealed an episode of ventricular flutter which reverted spontaneously to sinus rhythm. Transthoracic echocardiogram showed hyperechoic mass in the left ventricle. For further tissue characterization a cardiac magnetic resonance imaging was done which revealed a left ventricular mass with predominant fat content. The tumor was surgically resected. Histopathological examination confirmed the diagnosis of cardiac fibrolipoma. The patient recovered and is currently asymptomatic.

Crisscross heart with dextrocardia and intact interventricular septum.

Crisscross heart is a rare congenital heart disease characterized by a twisted atrioventricular connection, as a result of rotation of the ventricular mass along its long axis. We report an asymptomatic 48-year-old woman referred to us for evaluation of a cardiac murmur. Further evaluation showed situs solitus, dextrocardia with normal atrioventricular and ventriculoarterial connection, and a crisscross relation of the atrioventricular valves. Unlike the usual case of crisscross heart, our patient had an intact ventricular septum.

Aortopulmonary window: a rare mechanism of inter-circulatory mixing and prepared left ventricle in transposition of the great arteries with intact ventricular septum.

Transposition of the great arteries with intact ventricular septum and aortopulmonary window is an extremely rare anatomic combination associated with high morbidity and mortality. We report a case of a 3-month-old baby with d-transposition of the great arteries with intact ventricular septum and a large aortopulmonary window as a mechanism of inter-circulatory mixing.
