hydatid cyst disease should be considered in differential diagnosis in many doubtful clinical situations as can present with non-specific symptoms especially in the endemic areas. cardiac involvement should be considered in patients with history of previous hydatid cyst disease.. cardiac hydatid cysts account for less than 2% of all hydatid diseases. in this report we aimed to present a case of...

OBJECTIVE To determine whether regional hypoperfusion of the interventricular septum occurs during ventilation with positive end-expiratory pressure. DESIGN Animal study. ANIMALS Anesthetized, closed chest dogs (n = 8). INTERVENTIONS Induction of experimental adult respiratory distress syndrome (ARDS) and then ventilation with 10, 15, and 20 cm H2O of positive end-expiratory pressure. M...

ume overload was created in open-chest dogs by pumping blood from the left atrium to the right atrium. In seven of eight dogs changes in interventricular septum motion were produced acutely at shunt flow as low as 500 cc/min. When the shunt was decreased or stopped, interventricular septum motion returned to normal. Shunts producing left ventricular volume overload (aorta to left atrium and rig...

metastatic tumors to the heart unlike primary cardiac tumors are not rare. despite its frequency, cardiac metastasis is commonly detected only during autopsy as the symptoms of disseminated metastasis prevail over symptoms caused by cardiac metastasis and hence is overlooked most of the time. tumors more commonly found metastasizing to the heart are malignancies of lung, breast, esophagus, lymp...

We examined the function of the interventricular septum in six open-chest dogs by inserting piezoelectric crystals into the interventricular septum. Continuous ultrasonic recordings showed that the changes in myocardial chord length (MCL) in the septum and free walls of the right and left ventricle were similar during saline infusion and during pericardiotomy. End-diastolic MCL and myocardial s...

Aneurysm of the interventricular membranous septum is a very rare cardiac anomaly in the absence of ventricular septal defect. We report the case of a 22-year-old man with aneurysm of the interventricular membranous septum incidentally determined during aortic valve surgery. The patient underwent successful aortic valve replacement and aneurysm repair. Patients with the aneurysm of the interven...

The anatomy of the membranous part of the ventricular septum is described in 25 hearts from patients ranging in age from 15 weeks of gestation to the ninth decade of adult life. Both atrioventricular and interventricular components were recognised in all the adult subjects, and the atrioventricular component was evident in all 25. The interventricular membranous septum was present in only 1 of ...

1900 years ago Galen stated that blood seeps through the perforations in the interventricular septum. However, William Harvey, working 400 years ago, failed to find any. In this study an aqueous solution of a black dye was gently pumped by hand into the right ventricle of 20 porcine hearts. The area in the middle ofthe left muscular part of the interventricular septum in 13 of the hearts was bl...
