The impact of incomplete revascularization on survival in minimal invasive off-pump coronary artery surgery: a propensity score analysis of 1,149 cases.

Background: Minimally invasive concepts are increasingly influential in modern cardiac surgery. This study aimed to evaluate the effect of completeness of revascularization on clinical outcomes and overall survival in minimally invasive, thoracoscopic coronary artery bypass grafting (CABG) surgery.

Methods: We retrospectively evaluated a consecutive series of 1,149 patients who underwent minimally invasive off-pump CABG with single, double, or triple-vessel revascularization between 2007 and 2018.

Hybrid total arterial minimally invasive off-pump coronary revascularization and percutaneous coronary intervention strategy for multivessel coronary artery disease: a cohort study with a median 11-year follow-up.

Background: Hybrid coronary revascularization (HCR) is a treatment approach that combines the benefits of coronary artery bypass grafting (CABG) techniques such as minimally invasive direct coronary artery bypass (MIDCAB) or minimally invasive multivessel CABG (MICS-CABG) with percutaneous coronary intervention (PCI) for carefully selected patients with multivessel coronary artery disease (MV CAD). The extant body of research primarily concentrates on the comparison of outcomes between HCR and CABG or PCI. Furthermore, HCR is defined primarily as MIDCAB and PCI.

A propensity matched comparison of robotic traditional minimal access approach for mitral valve repair with concomitant cryoablation.

Background: Atrial fibrillation (AF) occurs frequently in patients with mitral valve disease. Results of cryoablation concomitant with either minimally invasive video-assisted [minimally invasive mitral valve surgery (MIMVS)] or with robotic-assisted (RMV) mitral valve surgery have previously been separately reported. However, there are up-to-date no studies comparing the two procedures in terms of safety, efficacy, and mid-term follow-up.

Minimally invasive strategies of surgical coronary artery revascularization for the aging population.

Background: The increasing prevalence of elderly or frail patients with severe coronary disease, who are not suitable for interventional coronary revascularization, necessitates the exploration of alternative treatment options. A less invasive approach, such as minimally-invasive off-pump coronary-artery-bypass (MICS-CABG) grafting through mini-thoracotomy, which avoids both extracorporeal circulation and sternotomy, may be more appropriate for this patient population. This study, a retrospective, monocentric analysis, aimed to evaluate the long-term outcomes of these patients.

A prospective, international, bicentric study to evaluate PremiCron suture material for cardiac valve surgery - PREMIVALVE a cohort study.

Unlabelled: The most common age-related heart valve diseases include aortic valve stenosis and mitral valve insufficiency. The suture material is not the focus of most studies. The aim of the study was to assess the performance of PremiCron suture material for cardiac valve reconstruction and/or replacement under clinical routine.

Concomitant intra-atrial excision of the left atrial appendage during robotic-assisted minimally invasive cardiac surgery.

Objective: Surgical closure of the left atrial appendage (LAA) in patients with atrial fibrillation undergoing cardiac surgery can decrease the risk of stroke and thromboembolism and should therefore be considered. In minimally invasive, thoracoscopic, or robotic-assisted mitral valve surgery, however, external procedures such as clip application or epicardial resection are not feasible due to anatomic limitations and the reduced size of the access port. Internal suture closing techniques bear the risk of recurrent LAA reperfusion, so far.

Robotically assisted mitral valve surgery-experience during the restart of a robotic program in Germany.

Background: Following the first robotic-assisted mitral valve operations in Paris and Leipzig, the era of this innovative technique expired after a few years in Germany. At that time, the main arguments against robotic surgery within the German cardiac surgical community were low cost effectiveness and operative time utilization. Encouraged by favorable results, we re-started our robotic-assisted cardiac program as the first and only center in Germany in 2019.

Surgical atrial appendage closure: time for a randomized study.

Atrial fibrillation (AF) is the most common arrhythmia and is assumed to affect more than 30 million people worldwide. Studies report that the left atrial appendage (LAA) plays an important role in thrombus formation and is considered the embolic source in 90% of affected patients with non-valvular and 57% with valvular AF. Oral anticoagulants have been the standard of care for stroke prevention in patients with AF for decades.

Cryopreserved aortic homograft, lifeline treatment for infected vascular prosthesis with mediastinal abscess in a re-redo case.

We report about a 61-year-old man who, 6 years after initial uncomplicated mitral valve repair and 3 months after treatment of a pseudo-aneurysm of the ascending aorta with a Dacron patch, was admitted in our institution with an infection of the vascular graft, which was associated with sternal osteomyelitis and purulent cutaneous fistula. In a re-redo procedure, the proximal aortic arch and the ascending aorta were replaced with a cryopreserved aortic homograft. The infected part of the sternum was resected and the defect was covered by mobilizing the mediastinal tissue and with a bilateral muscle flap.

Off-pump versus on-pump redo coronary artery bypass grafting: A propensity score analysis of long-term follow-up.

Objective: Redo coronary artery bypass grafting (CABG) is associated with an increased early mortality reported up to 16%. The aim of this study was to analyze the early and long-term results after redo CABG with special focus on the feasibility and safety of the off-pump technique in the setting of a high-volume off-pump CABG center.

Methods: From January 2006 to June 2015, isolated redo CABG was performed in 304 patients (179 = on-pump redo CABG, 125 = off-pump redo CABG).

A retrospective comparative study of minimally invasive extracorporeal circulation versus conventional extracorporeal circulation in emergency coronary artery bypass surgery patients: a single surgeon analysis.

Objectives: At the moment, the main application of minimally invasive extracorporeal circulation (MiECC) is reserved for elective cardiac operations such as coronary artery bypass grafting (CABG) and/or aortic valve replacement. The purpose of this study was to compare the outcome of emergency CABG operations using either MiECC or conventional extracorporeal circulation (CECC) in patients requiring emergency CABG with regard to the perioperative course and the occurrence of major adverse cardiac and cerebral events (MACCE).

Methods: We analysed the emergency CABG operations performed by a single surgeon, between January 2007 and July 2013, in order to exclude the differences in surgical technique.
