There are limited data on the occurrence of postoperative delirium after transcatheter aortic valve implantation (TAVI). We sought to investigate the incidence of delirium after TAVI and its impact on clinical outcomes. A total of 148 consecutive patients who underwent TAVI were enrolled. Of these patients, 141 patients survived hospital stay. The incidence of delirium was assessed in these patients for the first 4 days after the index procedure. The patients were divided into 2 groups based on the presence of delirium...

BACKGROUND: The frequency of circulating endothelial cells (CEC) in patients' peripheral blood can be assessed as a direct marker of endothelial damage. However, conventional enumeration methods are extremely challenging. We developed a novel, automated approach to determine CEC frequencies and tested this method on two groups of patients undergoing conventional (CAVR) versus trans-catheter aortic valve implantation (TAVI). METHODS: CEC frequencies were assessed by a flow cytometric approach, including automated pre-enrichment of CD34 positive blood cell subpopulation and isotype controls...

OBJECTIVE: Median sternotomy is still the standard approach for aortic arch surgery. Minimally invasive techniques promise faster recovery with shorter hospital stay due to thoracic stability, reduced pain, and superior cosmetic results. However, safety is a concern in complex aortic surgery. The aim of our study was to demonstrate that aortic arch surgery via partial upper sternotomy is viable, safe, and equivalent to standard procedure both in terms of its safety and the risk of major adverse cardiac and cerebrovascular events...

Here, we report concomitant resection of the left atrial appendage through the transverse sinus during minimally invasive aortic valve replacement via right anterolateral thoracotomy. The left atrial appendage was exposed by raising the collapsed ascending aorta and was safely resected using a surgical stapling device. This procedure is a feasible option in elderly patients, for whom a percutaneous procedure would be inappropriate, and could be useful for preventing thromboembolic and hemorrhagic complications...

The use of minimally, or less invasive, approaches to cardiac valve surgery has increased over the past decade. Because of its less traumatic nature, early studies in lower risk patients demonstrated the approach to be associated with an enhanced recovery, increased patient satisfaction, and good operative outcomes. With time, despite a steep learning curve, surgeons expanded this approach to perform more complex procedures, and include patients with more co-morbidity. The aim of this publication is to review the current literature involving the use of minimally invasive valve surgery (MIVS) in higher-risk patients...

BACKGROUND: Double valve surgery is associated with an increased peri-operative morbidity and mortality. A less invasive right thoracotomy approach may be a viable alternative to median sternotomy surgery in these higher-risk patients. METHODS: We retrospectively analyzed the baseline demographics, operative characteristics, and post-operative outcomes of patients who underwent minimally invasive double valve surgery between January 2009 and December 2011 at our institution...

BACKGROUND: In patients with prior cardiac surgery requiring re-operative coronary and valve surgery, a hybrid approach of percutaneous coronary intervention followed by minimally invasive valve surgery (PCI + MIVS) may be an alternative to the standard median sternotomy coronary artery bypass and valve surgery (CABG + valve). METHODS: The outcomes of patients with prior cardiac surgery, presenting with coronary artery and valvular disease, who underwent PCI + MIVS (N=39) were retrospectively compared with those who underwent CABG + valve (N=28) via a repeat median sternotomy, between February 2009 and April 2014...

BACKGROUND: The optimal treatment for concomitant two-vessel coronary artery disease (CAD) and moderate to severe ischemic mitral regurgitation (IMR) remains unclear. We compared the results of a staged percutaneous coronary intervention followed by minimally invasive mitral valve surgery (PCI+MIVS) versus combined coronary artery bypass graft and mitral valve surgery (CABG+MVS) in this population. METHODS: All consecutive patients with two-vessel CAD and moderate to severe IMR, who underwent PCI+MIVS or CABG+MVS at our institution between February 2009 and April 2014, were retrospectively evaluated...

Minimally invasive aortic valve replacement (AVR) aims to preserve the sternal integrity and improve postoperative outcomes. In low risk patients, this technique can be achieved with comparable mortality to the conventional approach and there is evidence of possible reduction in intensive care and hospital length of stay, transfusion requirement, renal dysfunction, improved respiratory function and increased patient satisfaction. In this review, we aim to asses if these benefits can be transferred to the high risk patient groups...

BACKGROUND: The del Nido cardioplegia (DC) procedure offers prolonged cardiac protection with single-dose administration and has proven safe in adult coronary artery bypass grafting (CABG) surgery. We set out to evaluate the efficacy of cardiac protection and clinical outcomes of DC versus standard blood cardioplegia (BC) in minimally invasive aortic valve surgery. METHODS: Between August 2011 and May 2016, 178 patients underwent minimally invasive aortic valve replacement (AVR) with BC (n = 101) or DC (n = 77)...

Surgical aortic valve replacement still represents the gold standard in patients with severe symptomatic aortic valve stenosis. In addition to conventional aortic valve replacement by mechanical or biological prostheses via a median sternotomy, novel approaches including minimally invasive strategies and new devices, such as so-called rapid deployment prostheses, are becoming increasingly more established. Autologous replacement strategies including the Ross and the Ozaki procedures have evolved into reliable options at selected centers of excellence...

Recently reported in Europe and United States, disseminated Mycobacterium chimaera infection is a novel clinical entity linked to point contamination of Stockert 3T heater-cooler units used for cardiopulmonary bypass. We present here the first two cases in Canada. Both patients presented with nonspecific extracardiac symptoms 1 year after undergoing minimally invasive mitral surgical repair. Before the right diagnosis was established, the patients were initially treated with prednisone for suspected sarcoidosis...

The aim of the study was to evaluate the treatment of minimally invasive mitral valve replacement (MIMVR) through a right minithoracotomy for patients with rheumatic mitral valve disease.From February 2009 to December 2016, 360 patients with rheumatic mitral valve disease underwent mitral valve replacement by the same surgeon. Among them, 150 patients accepted MIMVR through a right minithoracotomy, whereas the other 210 accepted a traditional median sternotomy. After matching by patients by age, sex, EuroSCORE, New York Heart Association (NYHA) classification, renal and liver function, and degree of mitral valve disease, we selected 224 patients for analysis in our retrospective study...

BACKGROUND Sutureless aortic valves were introduced to facilitate minimally invasive aortic valve surgery. Since sutureless aortic valves are a feasible procedure, we evaluated if any benefits could be identified in severe high-risk patients with active infective endocarditis of the aortic valve. MATERIAL AND METHODS Between April 2014 and April 2015, a total of 42 patients received a sutureless Perceval® aortic valve (Sorin Biomedica Cardio Srl, Saluggia, Italy) for different indications. Nine of these patients (median age 71 years, range 47-83 years) suffered from active infective endocarditis, including four patients with prosthetic aortic valve endocarditis...

Echocardiographic reduction of RV function, measured using TAPSE, is a well described phenomenon after cardiac surgery. The aim of the present study was to investigate the relation between the modality of pericardial opening (lateral versus anterior) and the postoperative right ventricular systolic function by comparing echocardiographic parameters in patients undergoing minimally invasive or traditional mitral valve repair. 34 patients with severe mitral regurgitation due to mitral valve prolapse underwent traditional (sternotomy) operation (Group A) or minimally invasive surgery with right anterolateral thoracotomy (Group B)...
