BACKGROUND: Lhasa is the main residence of Tibetans and one of the highest cities in the world. Its unique geography and ethnic population provide the chance to investigate the interactions among high altitude, ethnicity, and cardiac adaptation. Meanwhile, echocardiographic data about healthy Tibetans on a large scale are not available. This study aimed to analyze physiological factors related to ventricular size and valvular function in healthy Tibetans in Lhasa. METHODS: A representative sample of residents in Tibet was recruited using a multistage cluster random sampling method...

BACKGROUND: Reoperative cardiac valve surgery via sternotomy is associated with a substantial morbidity and mortality. This study evaluated the right anterolateral thoracotomy for high-risk patients undergoing mitral and tricuspid valve redo procedures. METHODS: Out of a series of 173 patients undergoing redo cardiac valve surgery, 24 patients were reoperative via the right anterolateral thoracotomy as the high-risk group on the basis of the proximity of the heart and great vessels to the sternum and the presence and location of patent bypass grafts...

BACKGROUND: The tricuspid valve can be considered the "forgotten" valve because in the past hardly any research has been conducted in this field and as a result only few therapeutic options existed. The prognosis of untreated tricuspid regurgitation (TR) is poor and mortality is high for patients with severe TR. Patients frequently return to medical practices and hospitals because of cardiac decompensation, with shortness of breath and leg edema. OBJECTIVE: Recent years have seen more development in catheter-based treatment options...

The hyperhemolysis paradigm that describes overlapping "hyperhemolytic-endothelial dysfunction" and "high hemoglobin-hyperviscous" subphenotypes of sickle cell disease (SCD) patients is based on North American studies. We performed a transversal study nested in the CADRE cohort to analyze the association between steady-state hemolysis and vascular complications of SCD among sub-Saharan African patients. In Mali, Cameroon, and Ivory Coast, 2,407 SCD patients (1,751 SS-Sβ(0), 495 SC and 161 Sβ(+)), aged three years old and over, were included at steady-state...

Background  Transcatheter heart valve (THV) therapies have shown to be an alternative to surgical valve replacement, especially in high-risk patients requiring redo surgery. However, reports of transcatheter-based interventions in tricuspid valve position are scarce. Case Description  Here, we report a case of successful concomitant transcatheter aortic valve-in-valve (ViV) and tricuspid valve-in-ring (ViR) procedures using a 23-mm CoreValve Evolut R THV (Medtronic, Inc., Minneapolis, Minnesota, United States) in aortic position and a 29-mm SAPIEN3 (Edwards Lifesciences, Inc...

Persistent left superior vena cava (LSVC) is a rare congenital anomaly. Its prevalence in the general population is 0.1 to 0.5%. LSVC is 5 times rarer when accompanied by an absence of the right superior vena cava (RSVC). We present the case of a 54-year-old man who carries a persistent LSVC without RSVC. Clinically, this patient presented a regular bradycardia at 40 per minute associated with a heart failure syndrome. The electrocardiogram diagnosed a complete atrioventricular block and transthoracic echocardiography showed dilated left heart cavities and a left ventricular ejection fraction of 50%...

Perinatal mortality remains high among fetuses diagnosed with Ebstein's anomaly of the tricuspid valve. The subgroup of patients with pulmonary valve regurgitation is at particularly high risk. In the setting of pulmonary valve regurgitation, early constriction of the ductus arteriosus may be a novel perinatal management strategy to reduce systemic steal resulting from circular shunt physiology. We report the use of chronic antepartum maternal oxygen therapy for constriction of the fetal ductus arteriosus and modulation of fetal pulmonary vascular resistance in a late presentation of Ebstein's anomaly with severe tricuspid valve regurgitation, reversal of flow in the ductus arteriosus, and continuous pulmonary valve regurgitation...

The tricuspid valve and the right ventricle are hemodynamically closely related. Pathological changes of the valve or of the ventricle itself and also various diseases beyond that can result in a downward spiral of mutual interference, which is of prognostic importance for the patient. The development of a functional tricuspid regurgitation is of great importance. Especially with the help of 3D-echocardiography, more and more changes and mechanisms have been identified that are crucial in this process. This article provides a review of the relationship between the tricuspid valve and the right ventricle emphasizing the current knowledge of the causes, the pathophysiological concepts, the underlying structural changes and the therapeutic approaches based on this...

There are two types of tumors found in the cardiac chamber. These are divided into primary intra-cardiac tumors and secondary intra-cardiac tumors. Primary intra cardiac tumors are rare and among them 29% are myxomas. Majority of them are found in the left atrium. Here, we report a case of a myxoma in the right atrium with hepatomegaly and Hepatitis B virus infection. The coexistence of all these conditions is very rare. A 52 years old patient presented with history of shortness of breath on exertion along with fever and generalized weakness for 6 months which aggravated lately for last 2 months...

Ebstein's anomaly is a rare congenital heart disorder, accounting for <1% of all cases of congenital heart disease. It is a congenital malformation of the heart that is characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialization of the right ventricle with a variable degree of malformation and displacement of the anterior leaflet. We report the case of a 25 years old female with Ebstein's anomaly which was associated with Ostium Secundum type of atrial septal defect and WPW syndrome, who presented with dyspnea, palpitations, cyanosis, clubbing and cardiomegaly...

We present our experience for patients who have undergone an anatomic repair (AR) for congenitally corrected transposition of the great arteries (CCTGA) at the Children's Hospital of Wisconsin. A retrospective chart review of patients who underwent AR for CCTGA from 2001 to 2015 was performed. The cohort consisted of 15 patients (74% male). Median age of anatomic repair was 15 months (range 4.5-45.6 months). Four patients had a bidirectional Glenn (BDG) prior to AR. At the time of AR,-9 (60%) underwent Senning/Rastelli procedure, 4 (26...

BACKGROUND: Accurate evaluation of the tricuspid regurgitant (TR) spectral Doppler signal is important during transthoracic echocardiographic (TTE) evaluation for pulmonary hypertension (PHT). Contrast enhancement improves Doppler backscatter. However, its incremental benefit with contemporary scanners is less well established. The aim of this study was to assess whether the TR spectral Doppler signal using contemporary scanners was improved using a second generation contrast agent, Definity® (CE), compared to unenhanced TTE (UE)...
