Even though the tricuspid valve is no longer “forgotten”, it still remains poorly understood. In this review, we focus on some controversial and still unclear aspects of tricuspid anatomy as illustrated by noninvasive imaging techniques. In particular, we discuss the anatomical architecture of the so-called tricuspid annulus with its two components (i.e., the mural and the septal annulus), emphasizing the absence of any fibrous “ring” around the right atrioventricular junction. Then we discussed the extreme variability in number and size of leaflets (from two to six), highlighting the peculiarities of the septal leaflet as part of the septal atrioventricular junction (crux cordis). Finally, we describe the similarities and differences between the tricuspid and mitral valve, suggesting a novel terminology for tricuspid leaflets.

AbstractEbstein’s anomaly is a rare congenital malformation of the right ventricle and tricuspid valve which is characterized by several features that can exhibit an infinite spectrum of malformation.The abnormalities include: i) adherence of the tricuspid leaflets to the underlying myocardium (failure of delamination); ii) anterior and apical rotational displacement of the functional tricuspid annulus (septal > posterior > anterior leaflet); iii) dilatation of the right atrioventricular junction (the true tricuspid annulus) with variable degrees of hypertrophy and thinning of the wall; iv) dilatation of the “atrialized” portion of the right ventricle; and v) redundancy, fenestration, and tethering of the anterior leaflet.

We describe a patient in whom we found dual orifices in a straddling and overriding tricuspid valve, with two normally sized ventricles and a cleft in the mitral valve. The patient underwent successful surgical repair. We discuss the concept of “double-orifice right atrium”, as well as the need to differentiate the isolated cleft of the morphologically mitral valve from the zone of apposition between the left ventricular components of the bridging leaflets seen in the setting of atrioventricular septal defect with common atrioventricular junction. We emphasise the unusual association of these abnormalities of the right and left atrioventricular valves in patients with separate atrioventricular junctions.

Abstract Background Primary cardiac tumours are extremely rare. Most of them are benign. Sarcomas account for 95% of the malignant tumours. Prognosis of primary cardiac angiosarcoma remains poor. Complete surgical resection is oftentimes hampered when there is extensive tumour involvement into important cardiac apparatus. We report a case of cardiac angiosarcoma of the right atrium and ventricle, infiltrating the right atrioventricular junction and tricuspid valve. Case presentation Initially, a 22-year-old man presented with dyspnoea. One year later, he had recurrent pericardial effusion. Afterwards, echocardiography revealed a large mass in the right atrium, expanding from the roof of the right atrium to the tricuspid valve. The mass was causing compression on the tricuspid valve, and another mass was seen in the right ventricle. Complete resection of the tumour was impossible. The mass was resected with the biggest possible margins. The right atrium was reconstructed using heterologous pericardium. The patient’s postoperative course was uneventful. Postoperative echocardiography showed a small mass remaining in the right side of the heart. Histopathology and immunohistochemistry confirmed the diagnosis of angiosarcoma. The patient underwent adjuvant chemotherapy and radiotherapy later on. He survived for 1 year and 5 days after the surgery. After a diagnosis of lung and brain metastases, he ended up on mechanical ventilation for 48 h and died. Conclusions Surgical resection combined with postoperative chemotherapy and radiotherapy is feasible even in patients with an advanced stage of cardiac angiosarcoma when it is impossible to perform complete surgical resection.

We herein present a case of infective endocarditis of the mitral valve and a paravalvular abscess around the tricuspid valve. Preoperative blood culture confirmed the presence of pathogenic diphtheroids. During the operation, an unexpected infection of the free wall of the right atrium (RA) near the tricuspid annulus was found. We harvested the left atrial appendage (LAA) en bloc. After resection of the infected and abnormal tissues, the resected LAA was used to reconstruct the RA. The infected mitral valve was replaced with a mechanical valve without any accident. Postoperative echocardiography showed that the RA had a supple shape, with no kinking.

Abstract Background Tricuspid valve (TV) stenosis is a very rare condition and the aetiology is primarily due to rheumatic disease, carcinoid disease, congenital heart disease, endocarditis, and following degeneration of biological valve prosthesis. Case summary We present a 45-year-old man with a rare case of symptomatic TV stenosis (TS) in a previously isolated TV repair. A meticulous multimodality diagnostic approach is presented in order to determine the severity of the TS and to evaluate the right ventricular function. Discussion This case report presents an integrated multimodality imaging and haemodynamic approach to evaluate and document the suspicion of development of a symptomatic significant stenosis in a previous TV repair. The initial TV repair was done without ring annuloplasty, because only the anterior leaflet was affected and bicuspidalization of the valve made it patent. In addition, minimizing the amount of implanted material was intended to minimize the risk of reinfection. The final treatment was performed as a TV replacement with insertion of a bioprosthesis.

Abstract Background Cardiac lipomas are rare benign primary tumours of the heart. Due to the nature of these tumours, they are often asymptomatic and diagnosed incidentally. Whether asymptomatic patients with cardiac lipomas should perform surgery still remains controversial. Case summary A 34-year-old Asian male who was incidentally found hyperechoic masses in the right ventricle (RV) on the transthoracic echocardiogram by annually routine physical examination was admitted to our cardiology department. His medical history was unremarkable. The repeated transthoracic and transoesophageal echocardiogram showed multiple solitary and well-demarcated masses in the RV. On the cardiac magnetic resonance imaging, four discrete masses (considering the possibility of it being a lipoma) partially occluding the right ventricular outflow tract (RVOT) were observed. During the open-heart resection surgery, it was found that the tricuspid valve and papillary muscle were covered by multiple adipose masses in the RV that arose from the interventricular septum and the free wall, resulting in partial RVOT obstruction. These excised masses were histopathologically confirmed as lipomata characterized by the mature adipocytes with entrapped myocardial cells. The patient had no cardiac abnormality in the 1-month follow-up after the surgery. Discussion This rare clinical case of multiple lipomata of the tricuspid valve and papillary muscle acknowledges that multimodality imaging is the cornerstone for the assessment and diagnosis. Surgery should be performed in cases of symptomatic or large lipomas as well as when a lipoma is considered to be high risk because of RVOT obstruction.

Unlike the tricuspid valve, the mitral valve has frequently received the attention of anatomists. Indeed, the drawings made by Leonardo da Vinci still retain their currency,1whilst it was no less a personage than Andreas Vesalius who, as far as we know, first likened the bifoliate appearance of the valve to the Episcopal mitre. It was also Vesalius who recommended that the two leaflets be described as aortic and mural, reflecting their respective relationships to the aortic valve and the parietal atrioventricular junction. It was Roberts and Perloff,2however, who emphasized the necessity, for clinical purposes, of analyzing not only the valvar leaflets, but also the overall valvar complex. As we will demonstrate in our review, this approach to analysis also proves its worth for the echocardiographic recognition of the congenitally malformed valve.

The unguarded tricuspid valve is uncommon. We describe herein a fetus with a grossly dilated right ventricle and atrium, with severe tricuspid and pulmonary valvar regurgitation. The right ventricle was akinetic, and no tricuspid tissue or valvar apparatus was identified. Colour Doppler showed a highly unusual retrograde flow of blood through the right heart. The pregnancy was terminated, and necropsy examination confirmed the gross dilation of the right heart chambers, with severely dysplastic valvar tissue at the right atrioventricular junction effectively giving an unguarded orifice. There was no valvar displacement, and the left heart was normal. The fetus had a normal karyotype, albeit with absent kidneys.
