Transoesophageal echocardiography is a simple technique which is now the object of a growing and well-deserved interest, due to the wealth of information it provides. This examination does not supersede the conventional transthoracic echocardiography, but it completes it by supplying more accurate data, especially in difficult clinical cases, such as mitral valve pathology, cardiac valve prostheses, intracardiac thrombosis, aortic dissection and septal abnormalities.

Percutaneous left atrial appendage closure using a modified single-operator-technician approach under deep sedation: A single-center experience.

Background: Historically, percutaneous transcatheter left atrial appendage closure (LAAC) has been performed under general anesthesia (GA) with transesophageal echocardiographic images obtained by a noninvasive cardiologist and usually requires an overnight hospital stay. Alternatively, we present our single-center experience performing LAACs under deep sedation (DS), employing an echocardiographic technician instead of a noninvasive cardiologist, and expediting same-day discharge. Mid- to long-term outcomes were also evaluated with follow-up imaging at a 45-day visit.

Background: Transcatheter aortic valve implantation (TAVI) is a safe and effective therapy for patients with severe aortic stenosis. A Stuck leaflet and severe intraprosthetic regurgitation after valve implantation occur rarely but can lead to sudden haemodynamic deterioration. We encountered a case of a stuck leaflet following post-dilatation with the Edwards Sapien 3 Ultra RESILIA valve.

Transcatheter edge-to-edge repair (TEER) is an effective intervention for high-risk patients with severe symptomatic mitral regurgitation (MR), but its acute impact on left ventricular (LV) function has not been well studied using advanced echocardiographic techniques. This study investigated the immediate effects of TEER on LV volumes and functions, as well as their influence on mid-term outcomes, using high-resolution 3D transesophageal echocardiography. In 80 patients undergoing TEER for severe MR (mean age 79±8 years, 49% with primary MR), LV end-diastolic volume (LVEDV) and stroke volume significantly decreased (161±61 to 147±54 ml and 69±18 to 50±15 ml, respectively), while end-systolic volume increased (92±60 to 97±45 ml; p<0.

Performing automatic and standardized 4D TEE segmentation and mitral valve analysis is challenging due to the limitations of echocardiography and the scarcity of manually annotated 4D images. This work proposes a semi-supervised training strategy using pseudo labelling for MV segmentation in 4D TEE; it employs a Teacher-Student framework to ensure reliable pseudo-label generation. 120 4D TEE recordings from 60 candidates for MV repair are used.

Severe mitral regurgitation (MR) following surgical repair of the mitral valve poses a significant clinical challenge. Patients who have undergone surgery are typically at high risk for a second operation. This report details the case of a 54-year-old male who underwent aortic valve replacement and mitral valve repair using a 34-ring, 14 years prior.
