• RHD is a rare cause of severe valvular AS. • Rheumatic MS typically accompanies rheumatic AV disease. • 2D and 3D echocardiography are essential in the assessment of rheumatic AS.

• Precise LAA anatomy must be established for LAA occlusion device selection. • We have developed the TUPLE maneuver, an acronym for “tilt up and turn left”. • The TUPLE maneuver facilitates LAA device selection and intraprocedural guidance.

Introduction: Gram-negative organisms of the AACEK group, formerly known as HACEK, rarely cause endocarditis.

Case Series: We present three cases of bacterial endocarditis, involving native and prosthetic valves, caused by AACEK organisms. In two patients, Cardiobacterium hominis was the responsible organism, and in a third, Aggregatibacter aphrophilus was implicated.

Infective endocarditis (IE) is a life-threatening disease associated with in-hospital mortality of nearly one in five cases. IE can destroy valvular tissue, which may rarely progress to aneurysm formation, most commonly at the anterior leaflet in instances of mitral valve involvement. We present a remarkable case of a patient with IE and a rare complication of a ruptured aneurysm of the posterior leaflet of the mitral valve.

• HIV and frequent methamphetamine use are two known risk factors for PAH development. • HIV and methamphetamine are both associated with higher rates of mortality in PAH. • Echocardiography is an effective noninvasive modality for assessing PAH severity.

Mitral regurgitation (MR) is one of the most commonly encountered valvular lesions in clinical practice. MR can be either primary (degenerative) or secondary (functional) depending on the etiology of MR and the pathology of the mitral valve (MV). Echocardiography is the primary diagnostic tool for MR and is key in determining this etiology as well as MR severity.

Partial anomalous pulmonary venous return (PAPVR) comprises a group of congenital cardiovascular anomalies associated with pulmonary venous flow directly or indirectly into the right atrium. Scimitar syndrome is a variant of PAPVR in which the right lung is drained by right pulmonary veins connected anomalously to the inferior vena cava. Surgery is the definitive treatment for scimitar syndrome.

• Idiopathic left ventricular aneurysm is a rare diagnosis. • Management and prognosis of idiopathic left ventricular aneurysms remain unknown. • We describe a conservative management of an idiopathic left ventricular aneurysm in a geriatric patient.

Lipomatous atrial septal hypertrophy (LASH) is a histologically benign cardiac lesion characterized by excessive fat deposition in the region of the interatrial septum that spares the fossa ovalis. The etiology of LASH remains unclear, though it may be associated with advanced age and obesity. Because of the sparing of the fossa ovalis, LASH has a pathognomonic dumbbell shape.

Contraindications to transesophageal echocardiography (TEE) include various esophageal pathologies, but compression of the esophagus by vertebral osteophytes is not listed in the current American Society of Echocardiography guidelines. We report a case of diffuse idiopathic skeletal hyperostosis (DISH) in an 81-year-old man who had incidentally been found to have extrinsic esophageal compression by cervical osteophytes prior to a proposed TEE. The incidence of esophageal perforation in patients with DISH and vertebral osteophytes is not well documented.

Article Synopsis
  • * Traditional surgical options for excluding the left atrial appendage (LAA) are often limited to patients undergoing other heart surgeries and may not always be completely effective.
  • * The LARIAT procedure offers a less invasive alternative by using a snare device for LAA exclusion, with early results showing it has a high success rate and low complications, highlighting the importance of real-time imaging guidance during the procedure.

Libman-Sacks endocarditis (LSE) is a common manifestation of valve disease in antiphospholipid syndrome. Mitral valve LSE is characterized by verrucous vegetations on the atrial surfaces of valve leaflets. In this report, mitral valve LSE was visualized by real time 3D transesophageal echocardiography (TEE).

A patient with atrial tachycardia presented with dyspnoea on exertion. Transoesophageal echocardiography revealed idiopathic left atrial appendage stenosis. The mouth of the atrial appendage was narrowed, and there was a high velocity to and fro jet between the left atrial body and the left atrial appendage.

Background: Few studies have evaluated concomitant pegylated liposomal doxorubicin (PLD) plus trastuzumab as therapy for HER2-overexpressing metastatic breast cancer (MBC). This open-label, prospective, phase II trial assessed the safety and efficacy of this regimen, with cardiac tolerance as the principal focus.

Patients And Methods: Women with HER2-overexpressing recurrent MBC, baseline left ventricular ejection fraction >or= 55%, and no history of serious cardiac illness were eligible; preexisting cardiac risk factors, including previous anthracyclines and previous trastuzumab for MBC, were allowed.

Severe aortic plaques seen on transesophageal echocardiography (TEE) are a high-risk cause of stroke and peripheral embolization. Evidence to guide therapy is lacking. Retrospective information was obtained regarding the occurrence of embolic events (stroke, transient ischemic attacks, or peripheral emboli) in 519 patients with severe thoracic aortic plaque seen on TEE since 1988.

Background: Aortic valve thickening (AVT) without aortic stenosis (AS) is common and was often considered benign. However, it has recently been found to be associated with increased morbidity and mortality. It is unknown whether patients with AVT are at risk for the development of AS.

Paradoxical septal motion has been reported as characteristic of Ebstein's anomaly. The patient reported here has the characteristic apical displacement of the tricuspid value, but septal motion is uncharacteristically normal. Because there is only mild tricuspid regurgitation, it is likely that the absence of right ventricular volume overload accounts for the normal septal motion in this patient.
