The midterm safety and feasibility of transcatheter aortic valve implantation (TAVI) for patients with a history of coronary artery bypass graft (CABG) and high operative risk are unclear. This study compared the midterm outcomes of patients undergoing TAVI with or without previous CABG surgery. Between October 2013 and July 2016, 1,613 patients underwent TAVI according to the Optimized CathEter vAlvular iNtervention (OCEAN)-TAVI registry (previous CABG: n = 120; no previous CABG: n = 1493). The propensity score comprised the variables of the Society of Thoracic Surgeons Score, previous myocardial infarction, peripheral artery disease, chronic kidney disease > stage 2 (estimated glomerular filtration rate < 60 mL/min/1...

BACKGROUND: In sub-Saharan Africa, continued clinical follow-up, after cardiac surgery, is only available at urban referral centres. We implemented a decentralised, integrated care model to provide longitudinal care for patients with advanced rheumatic heart disease (RHD) at district hospitals in rural Rwanda before and after heart surgery. METHODS: We collected data from charts at non-communicable disease (NCD) clinics at three rural district hospitals in Rwanda to describe the outcomes of 54 patients with RHD who received cardiac valve surgery during 2007-2015...

BACKGROUND: Current European Society of Cardiology Guidelines recommend concomitant atrial fibrillation (AF) ablation for all symptomatic patients undergoing other cardiac surgeries, but the safety and potential benefits of concomitant atrial fibrillation (AF) ablation at the time of double valve replacement (DVR: aortic and mitral valve replacement) remains unexamined. MATERIALS AND METHODS: We conducted a retrospective review of 238 patients with AF who underwent DVR with or without concomitant surgical ablation (Ablation group, n=113; Non-ablation group, n=125) at a single institute from April 2006 to September 2011...

Transcatheter aortic valve implantation (TAVI) is indicated in severe symptomatic aortic stenosis, when there is intermediate-high surgical risk, or a condition considered inoperable, as in the case of "porcelain aorta" that could turn clamping or cannulation of the ascending aorta hazardous in open-heart surgery. Among the complications of this less invasive procedure, intraventricular conduction disorders subsequent to the procedure stand out. TAVI causes worsening of intraventricular dromotropic disorders in more than 75% of the cases, with the presence of preexisting right bundle branch block and first-degree atrioventricular block, deep prosthesis implant, male gender, size of the aortic annulus smaller than the prosthesis, and porcelain aorta being predictive of requirement for permanent pacemaker implant...

INTRODUCTION: RHD is the leading cause of cardiovascular morbidity and mortality among young people. TOE is valuable in confirming valvular heart pathology. DISCUSSION: We present a patient with severe rheumatic heart disease involving all the heart valves. TOE confirmed severe mitral stenosis, severe aortic regurgitation, severe tricuspid regurgitation and stenosis and severe pulmonary stenosis. This was consistent with TTE findings preoperatively. The patient underwent successful quadruple valve replacement in a single operation...

BACKGROUND:  Isolated tricuspid valve (TV) surgery is considered a high risk-procedure. The optimal surgical approach is controversial. We analyzed our experience with isolated TV redo surgery performed either minimally invasively (redo-MITS) or through sternotomy. METHODS:  We retrospectively analyzed all patients with previous cardiac surgery who underwent redo-MITS ( n  = 26) and compared them to redo-Sternotomy ( n  = 17). A group of primary-MITS ( n  = 61) served as control...

Freeman-Sheldon syndrome (FSS) or "whistling face" syndrome is a rare congenital disorder complicated by characteristic facial deformities and muscular contractures. We report on a 64-year-old male patient presenting for surgical replacement of his aortic valve and review the available literature on anesthetic considerations and perioperative management principles. FSS frequently poses a significant challenge to airway management and gaining vascular access. Moreover, these patients are reportedly at risk for developing malignant hyperthermia (MH) or neuroleptic malignant syndrome...

BACKGROUND: As heart failure prevalence continues to increase in the setting of a static donor supply, left ventricular assist device (LVAD) therapy for end-stage heart failure continues to grow. Anecdotal evidence suggests that malalignment of the LVAD inflow cannula may increase thrombosis risk, but this effect has not been explored mechanistically or quantified statistically. Our objective is to elucidate the impact of surgical angulation of the inflow cannula on thrombogenicity. METHODS AND RESULTS: Unsteady computational fluid dynamics is used in conjunction with computational modeling and virtual surgery to model flow through the left ventricle for 5 different inflow cannula angulations...

With over 150,000 implantations performed over the world, transcatheter aortic valve replacement (TAVR) has become a surgical technique, which largely competes with open surgery valve replacement for an increasing number of patients. The success of the procedure favors the research toward synthetic valve leaflet materials as an alternative to biological tissues, whose durability remains unknown. In particular, fibrous constructions have recently proven to be durable in vivo over a 6-month period of time in animal sheep models...

Systemic inflammatory response syndrome (SIRS), initially reported after cardiovascular surgery, has been described after various interventional cardiology procedures, including endovascular/thoracic aortic repair (EVAR/TEVAR), implantation of heart rhythm devices, percutaneous coronary intervention (PCI), electrophysiology procedures (EP), and transcatheter aortic valve implantation (TAVI). In these settings, a comprehensive understanding of the triggers, pathogenesis as well as a common diagnostic/therapeutic algorithm is lacking and will be discussed in this review...

During the late 1950s and most of the 1960s, Dr John Ross and I led the busy clinical cardiology program then existing at the Clinical Center of the National Institutes of Health. During this period, the assessment and surgical treatment of severe aortic stenosis (AS) in adults, predominantly rheumatic in origin, were both undergoing rapid changes. In the 1950s, before open heart surgery and left-sided heart catheterization were available, after thoracotomy dilators were inserted through a ventriculotomy, and severely obstructed aortic valves were "blindly" opened...

BACKGROUND: A significant proportion of patients requiring aortic valve replacement (AVR) have undergone prior coronary artery bypass grafting (CABG). Reoperative heart surgery is associated with increased risk. Data on relative utilization and comparative outcomes of transcatheter (TAVR) versus surgical AVR (SAVR) in patients with prior CABG are limited. METHODS AND RESULTS: We queried the 2012 to 2014 National Inpatient Sample databases to identify isolated AVR hospitalizations in adults with prior CABG...

Tricuspid regurgitation (TR) is a common valvular lesion which may affect morbidity and mortality. It can be related to an intrinsic abnormality of the tricuspid valve leaflets (organic) or secondary to annular dilatation (functional). Often organic and functional TR coexist in the same patient. A long standing TR is associated with ascites, congestive hepatopathy, peripheral edema, renal failure, and abdominal fullness which significantly affect the outcome. In particular, the perioperative course may be complicated due to both the presence of comorbidities and the development of a severe postoperative right ventricle (RV) dysfunction...

BACKGROUND: Patients with atrioventricular septal defect (AVSD) may require pulmonary artery banding (PAB), either as a part of a staged uni-ventricular palliation or to allow delayed bi-ventricular repair in those presenting with early heart failure. The long-term outcomes of PAB in children with AVSD have not been previously reported. METHODS: All children with AVSD who underwent PAB at a single institution were included in the study. Data were obtained from medical records and correspondence with general practitioners and cardiologists...

Adaptation and evolution of transcatheter aortic valve replacement (TAVR) technologies has led to approval of TAVR for consideration in patients at intermediate risk for surgical aortic valve intervention. As TAVR becomes more mainstream, attention is shifting toward percutaneous mitral valve (MV) repair and transcatheter MV replacement (TMVR) techniques. Transcatheter heart valves (both purpose-built and off-label-use TAVR valves) are being implanted during TMVR procedures to treat clinically significant MV disease (native disease, degenerated bioprosthetic valves, and dysfunctional surgical MV annuloplasty repairs) when the risk of open heart MV surgery is prohibitive...
