A 17-year-old boy presented with facial puffiness and swelling in the lower limbs for 6 months and one episode of syncope 15 days earlier. Transthoracic echocardiography showed a dilated right atrium and right ventricle with right ventricular systolic dysfunction. The free wall of the right ventricle was thinned out and devoid of myocardium and trabeculations. Cardiac magnetic resonance imaging showed an extremely dilated thin-walled right ventricle and absence of trabeculations, with no fat signal in the right ventricular wall, in contrast to that seen in arrhythmogenic ventricular dysplasia, which confirmed the diagnosis of Uhl’s anomaly.

Background: The cardiovascular system is significantly agitated by loss of gravity. In microgravity, the body fluids shift toward the thoracic cavity, induced the heart becomes more spherical. This further increased the cardiac preload with an increasing of transmural central venous pressure, affects the right heart ventricles to tolerating the enhanced preload on the right ventricular wall. Method: In this study we investigated the rat right ventricle remodeling in simulating persistent microgravity by using tail-suspension model, examined the remolding of the heart and the specific STAT3 expression in right heart myocardium. Result: The results indicated that microgravity induced heart remodeling included a significant increasing of the ventricular weight in the left. However, the right ventricle was not increased significantly in the microgravity simulation rats. The histological study demonstrated that the outstanding development on right ventricular wall which included the gap junction remodeling and STAT3 signaling protein specific accumulation in the right ventricles. Conclusion: The results existed that the right cardiac ventricle has a distinctive remodeling process during microgravity simulation which was not the muscular hypertrophy and relative weight increasing, but manifested the STAT3 accumulation and the electrical gap junction remodeling. The effect of microgravity induced right ventricle remodeling and the STAT3 specific accumulation can be used for multi-purpose research.

To differentiate between the mechanisms which have been proposed to account for the hypotensive effect of pulmonary insufflation, cyclic volume changes of the right ventricle were qualitatively monitored by means of a variable resistance strain gauge sutured to the right ventricular wall. Artificially created decreases in venous return as well as cardiac tamponade of a degree sufficient to produce hypotension for brief periods were found to decrease the volume of the right ventricle. Increased right ventricular outflow resistance, however, produced a marked increase in right ventricular volume. With brief periods of hypotensive levels of pulmonary insufflation, right ventricular volume was found to increase in the animal with a wide-open chest; the volume decreased with the chest closed. It is concluded that in the open-chest condition the hypotensive mechanism of pulmonary insufflation is an increase in pulmonary vascular resistance, whereas in the closed-chest condition decreased venous return, cardiac tamponade, or both are predominantly responsible for the hypotension.

Sharp-object penetration into the chest is rare and may lead to life-threatening complications, hence the significance of early detection and removal. We present an uncommon case of the accidental penetration of a sewing needle into the chest of a 5-year-old girl, with the needle traveling from the entrance site to the right ventricle through the lung tissue. Due to the possibility of cardiovascular accidents, the patient was transferred to a special ward. For positioning and correct actions, TTE and CT scan of the chest with and without contrast were performed and the presence of a tangential needle with the right ventricular wall and inside the pericardium was reported. The patient was taken to the operating room, and after exploring, a 2 cm needle was inserted into the right ventricle and removed. The patient was discharged after 5 days.

Prognosis in pulmonary hypertension is strictly linked to right ventricle failure, which results from uncoupling between right ventricle function and its afterload. This study sought to describe how to estimate with echocardiography right ventricular wall tension, its correlation with right ventricle haemodynamics and its prognostic role. A total of 190 patients without overt right ventricle failure but with suspected pulmonary hypertension on a previous echocardiogram underwent right heart catheterization and nearly-simultaneous echocardiography. Right ventricular wall tension was estimated according to Laplace’s law as right ventricle length × tricuspid regurgitation peak gradient and it was correlated with right ventricle haemodynamic profile; its potential prognostic impact was tested along with canonical right ventricle function parameters. Right ventricular wall tension correlated significantly with invasive estimation of right ventricle end-diastolic pressure (R: 0.343, p < 0.001) and with several other haemodynamic variables, such as mean pulmonary artery pressure, pulmonary artery compliance, transpulmonary gradient, pulmonary vascular resistance, right atrial pressure and right ventricle stroke work index (all p < 0.001). At a mean follow-up of five years and three months, only right ventricular wall tension was associated to all-cause mortality ( p = 0.036), while tricuspid annular plane systolic excursion ( p = 0.536), right ventricle fractional area change ( p = 0.383), right ventricle fractional area change ( p = 0.076), tricuspid regurgitation peak gradient ( p = 0.107) and tricuspid annular plane systolic excursion/tricuspid regurgitation peak gradient ( p = 0.181) could not. We identified a novel bedside echocardiographic predictor of altered right ventricle haemodynamics, which is precociously altered in patients without overt right ventricle failure and is associated to all-cause mortality at a long-term follow-up. Further studies are needed to confirm its role in pulmonary hypertension patients.

Cardiac Rhabdomyosarcoma

A seven-year-old domestic shorthair (DSH) cat was presented with anorexia and dyspnea. Pleural-pericardial effusion was detected with thoracic radiographs and echocardiography. Echocardiography demonstrated a large, soft-tissue mass in the right ventricular wall, protruding both into the pericardial space and into the right ventricle. Postmortem examination findings included a large mass in the right ventricular wall and multiple smaller masses on the external surface of the left ventricle and on the internal surface of the pericardium. Results of the histopathological and immunohistochemical examinations of the masses were consistent with rhabdomyosarcoma. This is the first reported case of primary cardiac rhabdomyosarcoma in the cat.

A 43-year-old woman presented to the emergency room with a sustained ventricular tachycardia (VT). ECG showed a QRS in left bundle branch block morphology with inferior axis. Echocardiography, ventricular angiography, and cardiac magnetic resonance imaging (CMRI) revealed a normal right ventricle and a left ventricular diverticulum. Electrophysiology studies with epicardial voltage mapping identified a large fibrotic area in the inferolateral layer of the right ventricular wall and a small area of fibrotic tissue at the anterior right ventricular outflow tract. VT ablation was successfully performed with combined epicardial and endocardial approaches.

Arrhythmogenic dysplasia of the right ventricle is a rare pathology of the myocardium, the diagnosis of which is difficult. Isolated myocardial infarction of the right ventricle occurs and is diagnosed extremely rarely. In this article we describe a case of arrhythmogenic right ventricular dysplasia, complicated by transmural infarction of the anterolateral wall of the right ventricle, myocardial rupture, and cardiac tamponade.
