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.

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.

Left Atrial Dissection During Minimally Invasive Mitral Valve Surgery.

• LA dissection is a rare complication of cardiac surgery seen more often in MV repair. • It can present heterogeneously, from being benign to causing hemodynamic collapse. • Perioperative TEE is valuable in identifying LA dissection and aiding in management.

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.

Aortic regurgitation management: a systematic review of clinical practice guidelines and recommendations.

Guidelines for the diagnosis and management of aortic regurgitation (AR) contain recommendations that do not always match. We systematically reviewed clinical practice guidelines and summarized similarities and differences in the recommendations as well as gaps in evidence on the management of AR. We searched MEDLINE and Embase (1 January 2011 to 1 September 2021), Google Scholar, and websites of relevant organizations for contemporary guidelines that were rigorously developed as assessed by the Appraisal of Guidelines for Research and Evaluation II tool.

Leaflet thrombosis after valve-in-valve transcatheter aortic valve implantation: a case series.

Background: Valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) in degenerated surgical aortic valve replacement (SAVR) is an alternative to redo-SAVR. However, reports on leaflet thrombosis following ViV-TAVI are emerging and subclinical thrombosis has gained recent attention. Although the incidence of transcatheter heart valve (THV) thrombosis after TAVI for native aortic valve disease is low, current imaging studies suggest the incidence of subclinical THV thrombosis may be significantly higher.

Successful repositioning of apically tethered transcatheter mitral valve replacement in the off-bypass, beating heart.

A 73-year-old man with severe, symptomatic secondary mitral regurgitation (MR) underwent successful transcatheter mitral valve replacement using the Tendyne™ mitral valve system. The device was deployed from the left ventricular (LV) apex and secured in position by a tether attached to an epicardial pad. Three days postoperatively, the patient developed hemolytic anemia and a paravalvular leak (PVL) associated with indentation of the LV apex.

Cerebral oxygenation monitoring in patients with bilateral carotid stenosis undergoing urgent cardiac surgery: Observational case series.

Background: Patients with significant bilateral carotid artery stenosis requiring urgent cardiac surgery have an increased risk of stroke and death. The optimal management strategy remains inconclusive, and the available evidence does not support the superiority of one strategy over another.

Materials And Methods: A number of noninvasive strategies have been developed for minimizing perioperative stroke including continuous real-time monitoring of cerebral oxygenation with near-infrared spectroscopy (NIRS).

Anemia in cardiac surgery: next target for mortality and morbidity improvement?

Objective: To assess the effects of preoperative anemia on outcomes of cardiac surgery and to explore the trend in mortality over an 8-year period.

Methods: During the study period (2005-2012), all 1170 patients undergoing elective or urgent cardiac surgery and classed as anemic were included. A matched group of non-anemic 1170 patients was used as a control group.

National administrative data produces an accurate and stable risk prediction model for short-term and 1-year mortality following cardiac surgery.

Objectives: Various risk models exist to predict short-term risk-adjusted outcomes after cardiac surgery. Statistical models constructed using clinical registry data usually perform better than those based on administrative datasets. We constructed a procedure-specific risk prediction model based on administrative hospital data for England and we compared its performance with the EuroSCORE (ES) and its variants.

Role of topical application of gentamicin containing collagen implants in cardiac surgery.

Sternal wound infections (SWI) continue to be a major cause of concern after cardiac surgery. It leads to prolonged hospital stay and increased morbidity, mortality and increased hospital costs. Prophylactic systemic antibiotics have been used to prevent surgical site infection (SSI).

Continuity of care by cardiothoracic nurse practitioners: impact on outcome.

Objectives: There have been recent reports on increased mortality in British National Health Service hospitals during weekends. This study aimed to assess the impact on patient care following the introduction of nurse practitioner cover for the cardiothoracic ward, including weekends.

Methods: Prospectively collected and validated data of patients operated on from January 2005 to October 2011 were analyzed.

How does the 'Heart Team' decision get enacted for patients with coronary artery disease?

Objectives: A heart team approach has been recommended for managing patients with coronary artery disease. Although this seems to be a new concept, we have been developing such a practice for over 8 years. In this report, the enactment of the heart team decision is reviewed and possible improvement is discussed.

Effects of ultrafiltration and peritoneal dialysis on proinflammatory cytokines during cardiopulmonary bypass surgery in newborns and infants.

Objectives: To assess the impact of balanced ultrafiltration and peritoneal dialysis (PD) on plasma and urinary cytokines and renal dysfunction after cardiopulmonary bypass (CPB) surgery in newborns and infants.

Methods: Twenty-three newborns and infants weighing less than 7 kg and scheduled for operation on congenital malformation were enrolled in this descriptive open clinical study. All patients received conventional ultrafiltration in the CPB rewarming period.
