in addition to the liver, human hydatidosis has been reported in the lung, brain, abdominal viscera, muscles, and heart chambers. infarction of the brain has also been documented. arterial embolism of the lower extremities by hydatid cyst, however, is extremely rare. in the presented case, acute ischemia of the patient's left leg led to gangrene and amputation. complete workup for localiza...

A 28-year-old male with hemophagocytic lymphohistiocytosis presented with left ventricular dysfunction and cardiac arrest. Percutaneous cardiopulmonary support (PCPS) was initiated, but left heart distension developed with associated aggravation of pulmonary edema. Percutaneous transseptal left atrial sheath (28-Fr) drainage was incorporated into the PCPS venous circuit under fluoroscopic guida...

Heart vector location was estimated for 23 isolated, perfused rabbit hearts during paced ectopic beats. Twenty computer-processed signals, derived from the surface electrodes of a spherical electrolyte-filled tank containing the hearts, were optimally fitted with a locatable cardiac dipole every millisecond of the QRS and every 3rd msec of the ST-T interval. During the QRS, the computed heart v...

Background & aim: Congenital heart disease is one of the most common malformations at birth that require timely recognition and treatment. The aim of this study was to determine the prevalence and etiology of detected heart murmurs and association between congenital heart disease and heart murmurs. Recognition of murmurs etiology would help us to manage and treat them properly. Methods: In this...

To determine the possible relationship between left ventricular dilatation and heart rate changes provoked by the Valsalva maneuver (Valsalva ratio), we studied 9 patients with isolated chronic aortic insufficiency. Left ventricular systolic function was assessed by two-dimensional echocardiography and cardiac catheterization. All patients were asymptomatic (functional class I of the New York H...

a 16-month-old holstein heifer with a history of anorexia and respiratory distress was referred to the veterinary research and teaching hospital of tehran university. heart and lung sounds were inaudible on the left side but greatly increased on the right side. on electrocardiography (ecg), decreased amplitudes of ecg parameters were observed. ultrasonography results revealed a pleural effusion...

primary pleuropulmonary synovial sarcomas are rare soft tissue malignancies; combined metastatic involvement of the heart is extremely rare. in this case report, a 17-year-old female presented with a history of chest pain. chest radiographs revealed a round mass in the left upper hemithorax, and computed tomography (ct) showed a well-defined heterogeneous enhancing mass abutting the pleura. a c...
