OBJECTIVES: Mitral periprosthetic leakage (PPL) is a serious complication following valve replacement. Conflicting outcomes of surgical treatment have been reported in the presence of multiple previous cardiac operations and associated co-pathological conditions. METHODS: Sixty-five symptomatic patients (37 women, mean age 64.8 years) underwent conventional operations at our hospital from 2006 to 2015. Mitral PPL was the leading surgical indication, although associated procedures were included...

Objective: To summarize the results and clinical application experience of one-stage operation of epicardial permanent pacemaker implantation and cardiac surgery. Methods: From November 2014 to July 2016, 15 patients (9 males and 6 females) with ages ranging from 50 to 73 (63.5±6.2) years requiring cardiac surgery with bradycardia underwent one-stage operation of epicardial permanent pacemaker implantation and cardiac surgery. All operations were performed under general anesthesia with chest median incision approach...

OBJECTIVES: To investigate the feasibility and image quality of low-dose contrast computed tomography (CT) angiography with pulmonary artery (PA) protocol. BACKGROUND: Aortic stenosis is the most common valvular heart disease and transcatheter aortic valve replacement (TAVR) has evolved as an alternative method for surgical valve replacement in intermediate-risk and high-risk surgical patients. CT is essential for measurement of aortic annulus prior to TAVR. METHODS: Twenty patients underwent a low-dose contrast study with PA protocol and 20 patients underwent a traditional-dose study (traditional protocol)...

PURPOSE OF REVIEW: With widespread adoption of transcatheter aortic valve replacement, there has been a change in the approach to management of valvular heart disease. New interest has taken hold in transcatheter therapies for valvular heart disease, as well as research into pathophysiology and progression of disease. Additionally, several key trials have further refined our understanding of surgical management of valvular heart disease. This review will elucidate recent clinical trial data leading to changes in practice...

AIMS: The impact of pulmonary hypertension (PH) on in-hospital outcome of either surgical (SAVR) or transcatheter aortic valve replacement (TAVR) was analyzed. METHODS AND RESULTS: Data from all 107,057 patients undergoing isolated SAVR or TAVR in Germany between 2007 and 2014 was provided by the German Federal Bureau of Statistics. About 18% of patients with aortic valve stenosis suffered from PH. Patients with PH had more co- morbidities with consequently increased EuroSCORE (TAVR without PH: 12...

The emergence of the global pandemic of chronic diseases necessitates critical assessment of interventions that can be targeted at both the individual and population levels. Among cardiovascular diseases, the increasing prevalence of valvular heart diseases such as aortic stenosis parallels the rising burden of atherosclerotic cardiovascular diseases. As an alternative to surgical aortic valve replacement, technological innovation has allowed development of minimally invasive transcatheter aortic valve replacement (TAVR)...

OBJECTIVE: Valve-in-valve procedures using transcatheter aortic valves are increasingly performed to treat degenerated bioprosthetic surgical aortic valves because they are less invasive than redo aortic valve replacement. The objective of this study is to quantify the changes in aortic sinus blood flow dynamics before and after a valve-in-valve procedure to gain insight into mechanisms for clinical and subclinical thrombosis of leaflets. METHODS: A detailed description of the sinus hemodynamics for valve-in-valve implantation was performed in vitro...

BACKGROUND: The need for pacemaker implantation is a well-described complication of aortic valve replacement. Not so well described is the effect such an event has on long-term outcome. This study reviewed a 21-year experience at the Mayo Clinic (Rochester, Minnesota) with aortic valve replacement to understand the influence of early postoperative pacemaker implantation on long-term mortality rates more clearly. METHODS: This study retrospectively reviewed the records of 5,842 patients without previous pacemaker implantation who underwent surgical aortic valve replacement from January 1993 through June 2014...

BACKGROUND: Propensity score-matched analysis of the anterolateral minithoracotomy and the partial upper hemisternotomy vs the median sternotomy approach has not been reported to date for isolated aortic valve replacement. METHODS: From 2005 to 2013, isolated aortic valve replacement was performed through a partial upper hemisternotomy in 315 patients (38.9%), through a median sternotomy in 328 patients (40.5%), and through an anterolateral minithoracotomy in 167 patients (20...

The mainstay for the current treatment of severe aortic stenosis includes surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI). In patients with high operative risk TAVI is established as first line therapy. New data on intermediate and low risk groups demonstrate at least non-inferiority of TAVI against SAVR, and in the near future a consistently rising number of transcatheter procedures may be anticipated. The purpose of this review is to outline the decision making process, hence to illustrate the diagnostic algorithm and to provide criteria for a differentiated approach against the background of recent data...

The VARC (Valve Academic Research Consortium) for transcatheter aortic valve replacement set the standard for selecting appropriate clinical endpoints reflecting safety and effectiveness of transcatheter devices, and defining single and composite clinical endpoints for clinical trials. No such standardization exists for circumferentially sutured surgical valve paravalvular leak (PVL) closure. This document seeks to provide core principles, appropriate clinical endpoints, and endpoint definitions to be used in clinical trials of PVL closure devices...

BACKGROUND: Little is known about patients with severe symptomatic aortic stenosis (AS) who receive medical management despite evaluation at a heart valve treatment center. OBJECTIVE: We identified patient characteristics associated with medical management, physician-reported reasons for selecting medical management, and patients' perceptions of their involvement and satisfaction with treatment selection. METHODS AND RESULTS: Of 454 patients evaluated for AS at 9 established heart valve treatment centers from December 12, 2013 to August 19, 2014, we included 407 with severe symptomatic AS...

BACKGROUND: So far, the specific appearance of QRS complex, ST-segment, and T wave was observed in aortic stenosis (AS). S-wave dynamic change in leads V1 -V3 was not reported in AS. METHODS: In a single-center, prospective study, we included a total number of 1.175 patients who underwent surgical aortic valve replacement (AVR). We conducted 3-year gathering of patients with symptomatic and asymptomatic severe AS, and separated them by hemodynamic stability into groups A and B, through EFLV (of more or less than 50%), AVA (of more or less than 0...

The purpose of this study is to assess the result of total arch replacement(TAR) using manufactured frozen elephant trunk(FET) for chronic aortic dissection after initial repair including the effect of aortic remodeling by the FET. Between 2003 and 2015, we performed 11 TAR using manufactured FET. Initial repairs before were 9 ascending aortic replacements and 2 Bentall operations. The entry of residual dissection was located at arch in 7 and at distal anastomosis site in 4. There was no hospital death. The operative complication included 2 surgical site infection, 1 interstitial pneumonia and 1 paraplegia with almost full recovery...

BACKGROUND: Bundled Payments for Care Improvement (BPCI) initiatives were developed by Medicare in an effort to reduce expenditures while preserving quality of care. Payment model 2 reimburses based on a target price for 90-day episode of care postprocedure. The challenge for valve patients is the historically high (>35%) 90-day readmission rate. We analyzed our institutional cardiac surgical service line adaptation to this initiative. METHODS: On May 1, 2015, we instituted a readmission reduction initiative (RRI) that included presurgical risk stratification, comprehensive predischarge planning, and standardized postdischarge management led by cardiac nurse practitioners (CNPs) who attempt to guide any postdischarge encounters (PDEs)...
