The role and implications of left atrial fibrosis in surgical mitral valve repair as assessed by CMR: the ALIVE study design and rationale.

Background: Patients with mitral regurgitation (MR) commonly suffer from left atrial (LA) remodeling. LA fibrosis is considered to be a key player in the LA remodeling process, as observed in atrial fibrillation (AF) patients. Literature on the presence and extent of LA fibrosis in MR patients however, is scarce and its clinical implications remain unknown.

Robotic Mitral Valve Surgery.

Growing interest in minimalizing surgical trauma during heart procedures stimulated the development of robotic mitral valve surgery in the late 1990s. Initially, the new technology was slowly adopted in clinical practice. However, following encouraging results by teams that adopted robotic heart surgery early on, a growing interest in implementation of robotic mitral valve surgery has emerged.

Long-term follow-up of thoracoscopic ablation in long-standing persistent atrial fibrillation.

Objectives: Catheter ablation of long-standing persistent atrial fibrillation (LSPAF) remains challenging, with suboptimal success rates obtained following multiple procedures. Thoracoscopic ablation has shown effective at creating transmural lesions around the pulmonary veins and box; however, long-term rhythm follow-up data are lacking. This study aims, for the first time, to assess the long-term outcomes of thoracoscopic pulmonary vein and box ablation in LSPAF.

Left internal mammary artery injury and subsequent hypovolemic shock due to a hemothorax after subxiphoid pericardiocentesis in a postoperative cardiac surgery patient.

Multimodality imaging is recommended in patients in shock after seemingly uneventful pericardiocentesis. The aim of this study was to heighten awareness that LIMA injury can lead to a life-threatening hemothorax in postoperative cardiac surgery patients.

A new approach to determine the results of minimally invasive pulmonary vein isolation using a continuous loop monitor: preliminary results.

Objectives: Surgical ablation is a well-known treatment for atrial fibrillation (AF); however, little is known about the absolute success rate. The aim of this study is to compare the absolute pre- and postoperative incidence of AF after minimally invasive surgical ablation for paroxysmal AF.

Methods: Twenty consecutive patients (mean age 55 ± 8; 55% male) received a continuous loop monitor (CLM) 4 weeks prior to a minimally invasive pulmonary vein isolation (MIPVI).
