The Key Role of 3D TEE in Assessing the Morphology of Degenerative Mitral Valve Regurgitation.

Two-dimensional transthoracic echocardiography (2D TTE) and two-dimensional transesophageal echocardiography (2D TEE) are regarded as the main imaging techniques for the assessment of degenerative mitral valve regurgitation (DMVR). However, describing the complex morphology of DMVR with 2D TTE and 2D TEE remains at the very least challenging. Three-dimensional (3D) TEE is an ideal technique for illustrating the extremely variable morphology of DMVR, providing images of unparalleled quality in terms of anatomical detail.

Article Synopsis
- This study investigated the use of 3D intraoperative transesophageal echocardiography (3D-IOTEE) to understand the causes of residual mitral regurgitation (MR) after mitral valve repair and how it affects the need for mitral valve replacement (MVR).
- Out of 767 patients who underwent valve repair, 92 patients needed a second cardiopulmonary bypass due to residual MR, which were categorized based on the underlying causes.
- Results showed that different mechanisms of residual MR significantly influenced the rates of conversion to MVR, with inter-scallop malcoaptation being the most likely to lead to replacement surgery (68.8%), while others like suture dehiscence had
'Color Doppler stripes' make it difficult to diagnose the severity of valvular heart diseases: a report of two cases.

Article Synopsis
- Echocardiography is the standard imaging method for evaluating valvular heart disease but can be complicated by artifacts like the 'color Doppler stripe,' which can resemble severe conditions and lead to misdiagnosis.
- Two cases are presented where patients were mistakenly thought to have severe valvular issues due to these artifacts, emphasizing the importance of recognizing and accurately interpreting echocardiographic results.
- In both cases, echocardiographic techniques revealed that the strong color Doppler signals were not indicative of severe valvular disease but rather artifacts caused by specific anatomical structures, highlighting the need for careful analysis during assessments.
Echocardiographic clues of the "atrial pump mechanism" during cardiopulmonary resuscitation.

Division of Anesthesiology and Intensive Care, ASST Fatebenefratelli Sacco, "Luigi Sacco" Hospital - Polo Universitario, University of Milan, Via G.B. Grassi 74, 20157, Milan, Italy.
Article Synopsis
- This study investigates how atrial compression plays a role in CPR rather than focusing solely on the ventricles, specifically looking at the "atrial pump mechanism."
- A cohort of 40 patients who experienced cardiac arrest was analyzed with techniques like transesophageal echocardiography to measure the mechanical characteristics of atrial compression and its effects on blood flow.
- Results showed that 12.5% of patients had significant atrial compression, which correlated with better outcomes in terms of successful CPR, suggesting that this mechanism is important for maintaining blood flow and brain perfusion during resuscitation efforts.

Objectives: Ventricular septal defect (VSD) is a prevalent congenital cardiac anomaly. By enhancing the occluder design and optimizing procedural approaches, the indications for VSD closure can be broadened while minimizing associated complications. The utilization of fully biodegradable occluder holds promising potential in resolving conduction block issues encountered during VSD closure.
