  • Right-sided heart failure is a major problem among patients with congenital heart diseases, due to the prevalence of congenital heart defects and the association of pulmonary hypertension. More attention is focused on the structure of the right heart particularly in association with congenital heart defects and chronic lung disease. The right ventricle (RV) may support the pulmonary circulation, and sometimes the systemic circulation (systemic RV) in congenital heart defects. Despite major progress being made, assessing the RV remains challenging, often requiring a multi-imaging approach and expertise (echocardiography, magnetic resonance imaging, nuclear and cineangiography). Evidence is accumulating that RV dysfunction develops in many of these patients and leads to considerable morbidity and mortality. While there is extensive literature on the pathophysiology and treatment of left heart failure, the data for right-sided heart failure is scarce. Therefore RV function in certain groups of congenital heart disease patients needs close surveillance and timely and appropriate intervention to optimise outcomes. An understanding of RV physiology and hemodynamics will lead to a better understanding of current and future treatment strategies for right heart failure. This will review right-sided heart failure with the implications of volume and pressure loading of the RV in congenital heart diseases.

  • Recent advances in the surgical treatment of congenital disorders of the heart have necessitated an accurate preoperative diagnosis. Right heart catheterization has become widely accepted as a research tool and diagnostic test to detect the heart diseases, especially in the congenital heart anomalies. Right heart catheterizations were carried out in 50 cases of congenital heart diseases at Department of Thoracic and Cardiovascular Surgery, , Kyungpook National University Hospital, during the period of June, 1975 through September 1978. In age distribution, 27cases were below 10 years of age, 18 cases between 11 and 20, and 5 cases above 20 male to female ratio was 2.8:1. The distribution of congenital heart diseases was VSD [42%], TOF [36%], PDA [10%], ASD [8%], and PS[4%]. Of these, 44 cases [88%], were compatible with the clinical impressions that were made preliminarily before cardiac catheterization, and all the cases except 1 case of VSD was correlated well with the postoperative diagnosis. The right heart catheterization is considered to be reliable and accurate toll in the preoperative diagnosis of congenital heart diseases. These procedures caused complications such as left side hemiplegia [lcase], occlusion of the femoral artery [lcase], and transient ventricular tachycardia [1case], and so the complication rate of right heart catheterization was 6% [3 cases]. None of patients who have undergone right heart catheterization was died.

  • A 6-month-old male Ragdoll cat presented with exercise intolerance. On physical examination, there was a grade 2/6 systolic murmur at the right apex. Diagnostic tests, including SpO2 measurement, blood tests, radiography, echocardiography, contrast echocardiography, and electrocardiography, were performed. Severe right atrial dilation, tricuspid valve leaflets and orifice displacement, right ventricular atrialization, septal leaflet adherence, anterior leaflet tethering, and right atrioventricular junction dilation were noted on echocardiography, alongside a right-to-left atrial septal defect. Cor triatriatum dexter and left ventricular aneurysm were observed. We diagnosed this case as having Ebstein anomaly with rare congenital heart deformities; which is rare in cats.

  • Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare but fatal complication of cancer and causes pulmonary hypertension and acute/subacute right heart failure. PTTM is most commonly associated with gastric cancer and more rarely associated with pancreatic cancer. We report a case of progressive right heart failure associated with clinically diagnosed pancreatic cancer, suggesting PTTM.

  • Venovenous extracorporeal membrane oxygenation (VV ECMO) is often used in cases of severe respiratory failure, especially in patients considered for lung transplantation. However, because many lung diseases can ultimately result in right heart failure, the treatment of secondary right heart failure can present a challenge when the patient is already under VV ECMO support. In such cases, an oxygenated-right ventricular assist device (OxyRVAD) can be used. OxyRVAD is designed to maintain anterograde blood flow and prevent right ventricular distension. Moreover, the pulmonary arterial cannula can be inserted percutaneously. We report a case in which percutaneous OxyRVAD was successfully implemented to manage right heart failure in a patient with respiratory failure who was on VV ECMO.

  • In this paper, we propose an automatic segmentation method of left and right heart in computed tomography angiography (CTA) using separating energy function. First, we smooth the images by applying anisotropic diffusion filter to remove noise. Then, the volume of interest (VOI) is detected by using k-means clustering. Finally, we extract the left and right heart with separating energy function which we proposed to split the heart. We tested our method in ten CT images and they were obtained from a different patient. For the evaluation of the computational performance of the proposed method, we measured the total processing time. The average of total processing time, from first step to third step, was $14.39{\pm}1.17s$. We expect for our method to be used in cardiac diagnosis for cardiologist.

  • Bronchogenic carcinoma involving the carina has remained a challenging problem for thoracic surgeons. Carinal resection and reconstruction is limitedly indicated because this aggressive surgical approach has been reported to be associated with significant morbidity and mortality while long-term outcome has not been determined. Wesuccessfully performed carinal reconstruction and sleeve right upper lobectomy assisted with ECMO for a 60-year-old male with squamous cell carcinoma in the right upper lobe extending to the carina.

  • Criss-cross heart which is a cardiac malformation caused by abnormal rotation of the ventricles early in embryonic development, is rare but a double outlet of right ventricle in priss-cross heart is very rare. We experienced a case of criss-cross heart which is situs solidus, concordant atrioventricular connection and double outlet of rig t ventricle with remote ventricular septal defect of perimembranous inlet type. A 4-years old female was diagnosed as a double outlet of right ventricle in criss-cross heart after echocardiography, cardiac catheterization and cardiac angiography. The surgical correction was a intraventricular reconstruction of left ventricular outflow with 314 circle of 20 mm Hemashield vascular graft from the ventricular septal defect to the aorta. The patient had a temporary atrioventricular block but was recovered uneventfully, and a postoperative echocardiogram showed no left ventricular outflow obstruction, no intracardiac shunt.

  • Primary cardiac lipoma is an extremely rare condition. We reports a case of primary lipoma located mainly in the right atrium of the heart in a 58-year-old male patient. The initial presenting symptoms were dyspnea followed by rapidly progress!ve congestive heart failure. Echocardiogram revealed huge mass on right atrium with stalk arising from septum. Under cardiopulmonary bypass the mass was removed and revealed characteristic findings of lipoma on microscope. The patient was recovered without any problem. We would like to describe this case of rare tumor with the review of literatures.
