Metastatic tumors to the heart include lymphomas, sarcoma, leukemia, and melanoma. Of these, metastatic melanoma is the most common, and are usually hematogenous, where metastatic lesions can be present in the left ventricle, right atrium, and/ or the right ventricle. We present an atypical metastatic melanoma pattern, where cardiac metastasis originated by direct extension from the adjacent gastric mesentery. We also present our trans-cardiac resection approach, which was the safest way to access the cardiac metastasis intra-operatively without disrupting the tumor.

Cat Heart

The distribution of acetylcholine (ACh) in the cat heart was investigated by a pyrolysis-gas chromatography (PGC) method. The hearts were dissected into various regions and homogenized in acetonitrile in the presence of propionylcholine, internal standard. Following extraction with toluene and hexane, the choline esters were precipitated as the enneaiodide complex. The isolated choline esters were analyzed by PGC, and the peak corresponding to ACh was quantified. The compound extracted from heart tissue that eluted with the retention time of authentic ACh was identified by mass spectrometry as dimethylaminoethylacetate, the pyrolysis product of ACh. ACh concentrations were found to be higher in the atria than the ventricles. In both the atria and the ventricles, a higher content of ACh was found in the right than the left portions: right ventricle, 5.0 compared to left ventricle, 2.0 nmol/g; and right atrium, 16.8 compared to left atrium, 11.3 nmol/g. Some cats were subjected to a bilateral cervical vagotomy 3 wk before removal and analysis of heart tissue. Hearts from vagotomized cats contained less ACh than controls in the right ventricle (-31%), right atrium (-54%), SA node (-42%), and papillary muscle (-53%), but no decreases were found in the left ventricle, left atrium, or interventricular septum.

Primary Cardiac Tumors

Primary cardiac tumors are rare in children, usually consist of benign tumors like rhabdomyomas and fibromas that may spontaneously regress. Primary malignant tumors are extremely rare even in adults and very few paediatric cases were reported in literature. Rhabdomyosarcoma is a rare primary malignant tumor in children and most of the reported cases occur in right ventricle, left atrium and right atrium. We report a 15 month old child with primary rhabdomyosarcoma of left ventricle presenting in cardiac tamponade and circulatory failure.

Primary cardiac angiosarcoma is a rare tumor, and surgical resection is often required to relieve its symptoms. A 54-year-old male with a large primary cardiac angiosarcoma is described in this case report. The tumor was located in the right atrium and right ventricle. The bulk was resected with the right coronary artery (RCA), and partial right atrium and partial right ventricle resections were performed during cardiopulmonary bypass. The resected tumor measured 15 x 10 x 8 cm, and the histopathological diagnosis was well differentiated primary cardiac angiosarcoma. In the postoperative period, the patient was followed up for 22 months, and radiotherapy and chemotherapy were performed for metastases. The optimal therapy for cardiac angiosarcoma is still controversial, but combined treatment including surgical resection should be considered.

Hydatidosis disease is commonly localized in the lungs and liver and the radical treatment remains surgery. Cardiac hydatid cyst is a rare and particular location disease that can be associated with serious complications. The most common site in the heart according to the is the left ventricle. We describe a case of cardiac hydatid cyst localized between the right atrium and right ventricle on the tricuspid valve in a 15-year-old patient.

Aim. To study and compare the lesions characteristics of laser energy in heart ex vivo and in experimental large animals.Materials and methods. For the ex vivo experiment a pig heart was obtained from a local slaughterhouse. Laser applications were applied using power 15-30 W in the left and right ventricles 5-50 seconds in duration. Immediately after ablation, examination was performed to determine myocardial damage characteristics at each point. In the experimental study, 7 sheep were included, laser applications were performed under fluoroscopic control in the right atrium with power 10, 15 and 20 W, 10-25 s; in the right ventricle 20, 25 and 30 W for 10-40 s; and in the left ventricle 20, 25 and 30 W for 20-40 s. The animals were euthanized and macroscopic examination of laser lesions was performed.Results. A total of 27 laser applications were performed on the heart ex vivo, all lesions were visualized as white spots on the endocardial surface. The maximum lesion depth was 9 mm achieved when using 20 W /50 s, the maximum lesion diameter was 6 mm, when using 25 W /40 s. The minimum lesion diameter and depth were observed when using 30 W /5 s, 2x1 mm. A total of 48 laser applications were performed in experimental animals, in one experimental animal was observed a transmural lesion in the right atrium when using 15 W /20 s. In 3 out of 7 experimental animals, transmural lesions were observed in the right ventricle when using 20 W /30 s; 20 W /40 s and 30 W /10 s. In the left ventricle, transmural lesions were observed in 2 animals, using 15 W /20 s and 20 W /40 s. In the ex vivo study, there was a strong positive correlation between ablation energy and lesion depth (R=0.91, P<0.05) and lesion volume (R=0.73, P<0.05); while there was no such statistical correlation in vivo.Conclusions. Laser ablation 15-20 W for 15-40 s seems to be optimal for achieving the deepest lesions in the atrium and ventricular myocardium. In our small pilot study with fiberoptic catheter ablation on a beating heart there was no correlation between energy delivered and the depth and volume of necrotic myocardium.

Cardiac Cyst

Cardiac echinococcus is a rare affliction of the heart caused by the tapeworm Echinococcus granulosus. Primary echinococcosis of the heart represents 0.5–2% of all hydatid disease cases in endemic regions. It evolves slowly, explaining its rarity in children. We report the case of a 11-year-old child affected by a giant cardiac cyst of the left ventricle (LV). The patient underwent cardiac surgery and medical treatment. A retrospective review of the current literature was realized. We found 18 cases: the mean age was 11-years old. Nine cysts were localized in the LV, four in the interventricular septum, three in the right ventricle, and two in the right atrium. All underwent surgery except six patients. Routine echocardiographic screening may be useful in endemic regions where infestation is common. Cardiac echinococcus should be diagnosed in the early and uncomplicated stages and be removed surgically even in asymptomatic patients.
