Rationale: Redo surgeries after mitral valve repair are technically demanding. Procedures applying the NeoChord device (NeoChord Inc, St. Louis Park, MN) have proven to be safe and feasible in selected patients requiring mitral valve repair due to a leaflet prolapse or flail. However, its use for redo procedures after conventional surgical repair has not been well established yet.
Patient Concerns: We report the case of a 57-year-old man who presented with dyspnea upon exertion. The patient had undergone a minimally invasive surgical mitral valve repair because of a flail leaflet of the segments segment 2 of the posterior mitral valve leaflet (P2)/segment 3 of the posterior mitral valve leaflet (P3) 4 years before.
Diagnoses: Transesophageal echocardiography identified a relapse of severe mitral valve regurgitation. The recurring regurgitant jet was caused by a flail leaflet due to newly ruptured native chords.
Interventions: After discussion in an interdisciplinary heart team, we performed a minimally invasive off-pump redo procedure applying the NeoChord device under three-dimensional transesophageal echocardiographic guidance.
Outcomes: The echocardiographic result with only trivial residual mitral regurgitation as well as the further clinical course of the patient were favorable.
Lessons: As redo surgery after minimally invasive mitral valve repair is challenging, the NeoChord device represents a novel treatment option that does not require cardiopulmonary bypass.

Background: In developing countries, rheumatic mitral valve stenosis (MS) is still a problem and its progression leads to left atrial (LA) damage. Due to the complexity of the LA geometry, currently used techniques like antero-posterior dimension (LAD) and 2D echo derived LA volume (LAV) have several limitations that are corrected by 3D derived LA volumes in addition to functional evaluation.
Purpose: To assess the LA functions using 2D speckle tracking echocardiography and 3D transthoracic echocardiography in patients with clinically significant MS in comparison to normal healthy subjects.
Cardiovascular Disease-Specific Responses to Autonomic Denervation.

Department of Cardiovascular Surgery, General Hospital of Northern Theater Command, Shenyang, Liaoning, China. Electronic address:
Background: Calcium-mediated autonomic denervation has been shown to suppress postoperative atrial fibrillation (POAF) after coronary artery bypass grafting.
Objectives: This study sought to evaluate whether similar autonomic denervation can prevent POAF after mitral or aortic valve surgeries.
Methods: This research consisted of 2 single-center, randomized, double-blind, sham-controlled trials: CAP-AF2 (Calcium Autonomic Denervation Prevents Postoperative Atrial Fibrillation in Patients Undergoing Isolated Mitral Valve Surgery for Mitral Regurgitation) for mitral valve (MV) surgery and CAP-AF3 (Calcium Autonomic Denervation Prevents Postoperative Atrial Fibrillation in Patients Undergoing Isolated Aortic Valve Surgery) for aortic valve surgery.
