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.

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.

Actuality. Arterial hypertension (AH) is the main risk factor for the development of cardiovascular diseases, disability and cardiovascular mortality. Episodes of blood pressure (BP) increase during the day in patients receiving antihypertensive therapy are an unfavourable factor contributing to the development and progression of cardiac remodeling. Aim. The purpose of the research is to study the features of changes in the structural and functional state of the heart under the influence of high blood pressure at night in patients with arterial hypertension with the dynamic three-year observation. Material and methods. 47 patients with the diagnosis of AH were examined. Patients were divided into two groups, randomized by age, duration and severity of AH. Group 1 included 24 patients who as a result of ambulatory blood pressure monitoring (ABPM) on the background of combined antihypertensive therapy suffered from constantly increased BP at night. The second group combined 23 patients without the increase in BP during the night according to the ABPM with antihypertensive therapy. The examination included measurement of the office BP, ABPM, two-fold echocardiography with a three-year interval. Results. When assessing the indices of office BP in the groups, there were no significant differences, all patients achieved the target values of BP. In patients in Group 1, higher values of BP were observed during the day, according to ABPM. Echocardiography over a three year period of observation revealed a more pronounced increase in diastolic interventricular septum thickness, the thickness of the left ventricle posterior wall during diastole, sizes of left atrium in the patients of the first group, patients of the second group had a more pronounced thickness of the left ventricle posterior wall during systole. The increase in the size of the right ventricle was revealed in both groups. Conclusions. 1) In patients with the increase in blood pressure at night, the values of BP variability were higher during the day. 2) Three-year dynamic observation revealed that the increase in BP at night in patients with hypertension facilitated acceleration of cardiac remodelling and was associated with an increase in the left ventricular posterior wall, interventricular septum thickness, the size of the left atrium, and the size of the right ventricle.

Pulmonary chronic heart (CPC) is an enlargement associated or not with dilation of the right ventricle. Objective: To recall the echocardiographic-Doppler aspects essential for the screening of pulmonary chronic heart. Patients and method: Retrospective study carried out between January 2009 and April 2019 interesting the cases of pulmonary chronic heart. Results: out of 124 cases of pulmonary chronic heart, 11 cases were included. These were four men and 7 women with a mean age of 63 ± 19 years (range: 20-84 years). The radiological and electrical semiology of pulmonary chronic heart was found, lacking specificity and sensitivity. Dilation of the right heart chambers, dyskinesia of the interventricular septum and hypertrophy of the free wall of the right ventricle ˃ 5 mm were observed. The mean maximum velocity of tricuspid insufficiency on continuous Doppler was 4.6 ± 1.32 ms / s (Extremes: 3.59-7.58 m / s) and the mean dilation of the inferior vena cava was 23.2 ± 3.9mm (Extreme: 21.2-27mm). Conclusion: CPC is uncommon and predominant in women. The EKG and chest X-ray are first-line exams without sensitivity or specificity. Screening for CPC is based on echocardiographic-Doppler criteria. The right cardiac catheterization remains the key examination.

The temporary pacing is provided as a key principle of maintenance and correction of hemodynamics after weaning the patient from cardiopulmonary bypass. There are conventional algorithms of temporary pacing, but the substantiation of electrode fixation areas is variable. The authors experimentally investigated the efficacy of temporary epicardial pacing in DDD and DDDBV using 18 laboratory animals after cardiac surgery with application of cardiopulmonary bypass. The hemodynamic parameters were compared in given groups. It was noted that in case of temporary epicardial pacing in DDDBV conditions was the best hemodynamic effect. The authors recommended more optimal areas for electrode fixation in temporary pacing: bachmans bunble (closest to the artrial septum), proximal part of the crista terminalis for the right atrium electrodes; the front-side free wall of the right ventricle at the distance of 3-4 cm from the apex of the heart, diaphragmatic surface of the right ventricle proximal to artioventricular groove for the right ventricle electrodes; obtuse margin (side wall of the left ventricle), diaphragmatic surface of the left ventricle proximal to artioventricular groove for the left ventricle electrodes.

Abstract Ventricular shunting is a well-recognised and commonly practiced method of reducing increased intracranial pressure in patients with neurologic pathology. There are possible complications related to shunt implantation, where the rarest is intracardiac migration of the distal shunt catheter. We present a case where the distal catheter migrated into the right ventricle, causing extrasystoles and was complicated with acute right ventricle failure during the endovascular shunt evacuation procedure.

Hypothermia is a situation in which the internal body temperature drops below 35 degrees Celsius. The article presents the relevance, theoretical aspects and features of the action of general hypothermia on the heart in general and cardiomyocytes in particular. The purpose of the study was to study the changes in the myocardium under the action of general hypothermia at different levels of structural organization. The object of the study were the hearts of laboratory adult rats. The study involved 20 animals. The longitudinal section shows that the right ventricle is much thinner than the left and its cavity is presented in the form of a crescent. The interventricular septum is thicker than the wall of the right ventricle and goes into its cavity. Results. To establish the shape of the heart and track the dynamic changes at the organ level, we calculated an index showing the ratio of the width of the heart to its length. In 80% of cases, the heart shape of intact rats was conical, the index averaged 55%, only 20% elliptical, the index was more than 65%. We did not observe other forms of heart in the group of intact rats. In the experimental groups, a spherical heart shape appeared. The thickness of the anterior wall of the left ventricle for 10 days from the beginning of the experiment was 3.15±0.11 mm, the side wall 3.1±0.11 mm, the posterior wall 2.45±0.04 mm, interventricular septum 2.95±0.09 mm. In the right ventricle, the thickness of the anterior wall is 1.04±0.03 mm, the posterior wall is 1.36±0.04 mm. On the 30th day from the beginning of the experiment, the thickness of the anterior wall of the left ventricle was 3.21±0.11 mm, the side wall 2.65±0.06 mm, the posterior wall 3.27±0.09 mm, the interventricular septum 3.14±0.13 mm. In the right ventricle, the thickness of the anterior wall is 1.09±0.04 mm, the posterior wall is 1.38±0.03 mm. Conclusions. The increase in heart mass, change in its shape due to changes in the middle third of the heart wall of both the left and right ventricles. The highest rates were in the middle third of the heart (zone "B"): In all layers of the myocardium there is an increase in the diameter of cardiomyocytes, a decrease in the distance between individual cardiomyocytes and their groups. The distance between adjacent cardiomyocytes in the left ventricle is: in the outer layer 1/8 of the diameter of the cardiomyocyte, between groups of cardiomyocytes 1/4 of the diameter of the cardiomyocyt

Abstract We describe a rare case of high-grade osteosarcoma with intravascular extension to the right atrium and right ventricle in a 23-year-old woman. Osteosarcomas rarely metastasize to the heart, and only a few cases have been reported in the literature thus far. Diagnoses in some of these cases were made during investigation for severe cardiac failure and in most of these cases at autopsy. We describe a unique case of intravascular extension of the tumor embolus in a cordlike fashion from the left femoral vein to the right side of the heart that morphologically resembled a chondrosarcoma.

The locations, projections, and functions of the intracardiac ganglia are incompletely understood. Immunocytochemical labeling with the general neuronal marker protein gene product 9.5 (PGP 9.5) was used to determine the distribution of intracardiac neurons throughout the cat atria and ventricles. Fluorescence microscopy was used to determine the number of neurons within these ganglia. There are eight regions of the cat heart that contain intracardiac ganglia. The numbers of neurons found within these intracardiac ganglia vary dramatically. The total number of neurons found in the heart (6,274 ± 1,061) is almost evenly divided between the atria and the ventricles. The largest ganglion is found in the interventricular septum (IVS). Retrogradely labeled fluorescent tracer studies indicated that the vagal intracardiac innervation of the anterior surface of the right ventricle originates predominantly in the IVS ganglion. A cranioventricular (CV) ganglion was retrogradely labeled from the anterior surface of the left ventricle but not from the anterior surface of the right ventricle. These new neuroanatomic data support the prior physiological hypothesis that the CV ganglion in the cat exerts a negative inotropic effect on the left ventricle. A total of three separate intracardiac ganglia innervate the left ventricle, i.e., the CV, IVS, and a second left ventricular (LV2) ganglion. However, the IVS ganglion provides the major source of innervation to both the left and right ventricles. This dual innervation pattern may help to coordinate or segregate vagal effects on left and right ventricular performance.
