The right ventricle is now recognized as being integral to cardiac mechanics and analysis of its function is an essential part of any echocardiogram performed in the critically ill patient. However, it has a complex triangular conical shape and is located retrosternally making it difficult to image. Unlike the left ventricle (LV) with its myocardial fibres in many different directions, the right ventricle (RV) has a predominance of longitudinal fibres with most of its movement being in a basal to apex direction. This makes it sensitive to analysis with speckle tracking echocardiography analysis of longitudinal strain: commonly reported as right ventricle free wall strain. Strain is a measure of relative myocardial deformation analysed through tracking of the speckles that make up the myocardium on the two-dimensional B-mode image. It is a postprocessing imaging tool and experience in echocardiography is required before tackling this form of assessment. Strain is sensitive, reproducible, angle independent, not prone to translational error like other conventional echocardiography tools and most importantly can recognize cardiac dysfunction and mechanics that cannot be described by other non-invasive imaging techniques. No echocardiography parameter used to assess right ventricle function is perfect, including right ventricle strain assessment. However its advantages are witnessed by the fact that it has entered clinical practice (exclusively to cardiology departments at this stage) in many larger centres around the world.

Tomography Scan

A 77-year-old woman presented with shortness of breath 1 year after a right upper lobectomy for lung cancer. She showed a possible intracardiac metastasis on positron emission tomography scan. There was no other evidence of recurrence. The large right ventricular mass was associated with the right ventricle free wall, the apex, the papillary muscle, and the chordae to the tricuspid valve. After mass resection of the right ventricle, a one-and-a-half ventricular repair was performed with tricuspid valve replacement and defect closure. The patient was discharged on postoperative day 14 without complications and has been well for the first 3 months after the surgery.

Abstract Aims Venous thromboembolism represents frequent complication of patients with severe COVID-19 disease. Several reports about atypical thrombosis are described, rarely it has been described a right venticular thrombus during the course of infection. We report a case of right endoventricular thrombosis in a patient with SARS-Cov-2 pneumonia. Methods and results A 58-year-old man was admitted to our ward for severe respiratory failure in interstitial pneumonia. The nasopharyngeal swab for COVID-19 resulted positive. Steroids and prophylaxis with LMWH were started, associated to CPAP to maintain good gas exchange. During hospitalization a venous ECD was performed with evidence of left popliteal thrombosis despite the therapy. d-Dimer was 4463  ng/ml. A new onset AF was documented at the telemetry, without troponin elevation. A cardiac ultrasound was performed showing a right endoventricular lesion of 1.8  cm adhering to the free wall of the right ventricle. A CT-pulmonary angiogram (CTPA) resulted negative for pulmonary embolism and confirmed suspected right ventricular thrombus. Treatment with fondaparinux 7.5 mg was started. After 10 days, cardiac ultrasound shown complete resolution of thrombosis, and CT confirmed the disappearing of the mass. Dabigatran 150  mg twice/day was started. Patient clinically improved and he was discharged after 20 days of hospitalization. Conclusions SARS-CoV-2 infection may cause inflammation with cytokine storm and hypercoagulability leading to venous thromboembolism. Atypical thrombus formation was reported, including right-ventricle free wall. Early caridac ultrasound was critical to make diagnosis and starting prompt treatment, therefore routine cardiac ultrasound is mandatory in severe COVID-19 patients.

Membranous ventricular septal aneurysm was diagnosed by echocardiography in 17 dogs and three cats. The aneurysm appeared as a thin membrane protruding into the right ventricle from the margins of a congenital ventricular septal defect (VSD). The aneurysm was intact in nine dogs and two cats and perforated by a small VSD in eight dogs and one cat. Other congenital heart defects were present in seven dogs. In all animals, the aneurysm was an incidental finding observed during echocardiographic examination, and it did not appear to directly cause any cardiac dysfunction.

AbstractSystemic forms of amyloidosis affecting the heart are mostly light-chain (AL) and transthyretin (ATTR) amyloidoses. The latter is caused by deposition of misfolded transthyretin, either in wild-type (ATTRwt) or mutant (ATTRv) conformation. For diagnostics, specific serum biomarkers and modern non-invasive imaging techniques, such as cardiovascular magnetic resonance imaging (CMR) and scintigraphic methods, are available today. These imaging techniques do not only complement conventional echocardiography, but also allow for accurate assessment of the extent of cardiac involvement, in addition to diagnosing cardiac amyloidosis. Endomyocardial biopsy still plays a major role in the histopathological diagnosis and subtyping of cardiac amyloidosis. The main objective of the diagnostic algorithm outlined in this position statement is to detect cardiac amyloidosis as reliably and early as possible, to accurately determine its extent, and to reliably identify the underlying subtype of amyloidosis, thereby enabling subsequent targeted treatment.

Accurate assessment of right ventricular geometry and function is of high clinical importance. However, several limitations have to be taken into consideration if using conventional echocardiographic parameters. Advanced echocardiographic techniques, such as speckle-tracking analysis or 3D echocardiography are reliable and simple tools providing a cost-effective and non-invasive alternative of current modalities used to characterize the right ventricle. There is a growing interest in the diagnostic and prognostic value of these methods regarding pathological (right ventricular infarction, pulmonary hypertension, arrhythmogenic right ventricular dysplasia, follow-up of heart transplantation) and even physiological (athlete’s heart) alterations of the right ventricle.
