BACKGROUND: Current guidelines recommend transcatheter aortic valve replacement (TAVR) in patients with severe symptomatic aortic stenosis (AS) who are not suitable for conventional surgical aortic valve replacement (SAVR). In light of the recent trend in performing TAVR in patients with lower risk profile, we assessed the midterm outcome comparing TAVR and SAVR for the treatment of patients with severe AS at low to intermediate risk. METHODS: PubMed, EBSCO, and Cochrane CENTRAL were systematically searched for randomized controlled trials that reported the clinical outcomes of TAVR versus SAVR in patients at low to intermediate surgical risk with at least 2 years of follow-up...

Pregnant women with stenotic degeneration of bioprosthetic cardiac valves may require another valve replacement procedure when their symptoms deteriorate with progression of pregnancy, but fetal mortality is higher with cardiac surgery done on cardiopulmonary bypass. Transcatheter valve-in-valve implantation may help to improve the fetal and maternal outcomes in these situations. Double valve-in-valve implantation is rare and has not been reported in a pregnant patient. We report, for the first time, the case of a pregnant woman with stenotic bioprosthetic valves in the mitral and aortic positions, who underwent a successful concomitant, transcatheter, double valve-in-valve implantation through the left ventricular apical route during the second trimester of her precious pregnancy...

BACKGROUND: Previous studies have demonstrated that three-dimensional (3D) transesophageal echocardiography (TEE) is an alternative to multi-detector computed tomography (MDCT) for aortic valve sizing in transcatheter aortic valve replacement (TAVR). However, conventional cross-sectional analysis of aortic annulus by 3D TEE has some limitations such as lengthy analytical time. A novel software for automated valve measurement has been developed for 3D TEE. We evaluated the accuracy and analytical time of aortic annular measurements using this novel automated software in the clinical setting...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has emerged as an alternative to surgical aortic valve replacement (SAVR), but unbiased data regarding evolution of the treatment of patients with aortic stenosis at the nationwide level are scarce. OBJECTIVES: This study sought to evaluate the number of aortic valve replacements (AVRs) performed in France, changes over time, and the effect of the adoption of TAVR. METHODS: Based on a French administrative hospital-discharge database, the study collected all consecutive AVRs performed in France between 2007 and 2015...

BACKGROUND: Type A aortic dissection (AAD) is a devastating complication of thoracic endovascular repair (TEVAR). In elderly patients, surgery for AAD carries considerable morbidity and mortality. Repair of AAD after previous TEVAR is an even greater challenge as it usually requires the arch to be addressed and a preexisting stent graft to be included into the aortic repair. METHODS: A case series of 5 elderly patients who presented with acute AAD after previous TEVAR was reviewed...

A major concern regarding transcatheter aortic valve replacement (TAVR) is leaflet thrombosis. Four-dimensional computed tomography (4D-CT) is the preferred imaging modality to evaluate patients with suspected valve thrombosis. To date, the abnormal findings visualized by 4D-CT suggestive of leaflet thrombosis have lacked pathologic confirmation from a surgically explanted valve in a surviving patient. Herein, we provide pathologic confirmation of thrombus formation following surgical explantation of a thrombosed TAVR prosthesis that was initially identified by 4D-CT...

Obtaining neuroimaging in patients on cardiopulmonary support devices such as extracorporeal membrane oxygenation (ECMO) can be challenging, given the complexities in monitoring, instrumentation, and associated hemodynamic lability. Transcranial Doppler (TCD) is used as an ancillary test for the assessment of cerebral circulatory arrest, but its use in non-pulsatile blood flow in venoarterial (VA) ECMO is not well described. We report the use of TCD in a patient on VA ECMO post-cardiac arrest for evaluation of death by neurological criteria...

Libman-Sacks endocarditis is a relatively rare sterile verrucous vegetative lesion observed in systemic lupus erythematosus (SLE)/antiphospholipid syndrome (APLS) patients. Most patients with this condition are asymptomatic. Here we report a case of a 46-year-old woman with APLS secondary to SLE complicated with frequent thromboembolic events due to a mitral valve mass. We performed minimally invasive mitral valve replacement with a mechanical prosthetic valve, and she was successfully discharged 14 days after surgery...

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...

This case describes an unusual presentation of prosthetic valve endocarditis: an acute coronary syndrome. A 67-year-old gentleman presented with cardiac sounding chest pain on a background of a short history of night sweats, weight loss and general malaise. Four months previously he had undergone bio-prosthetic aortic valve replacement for severe aortic stenosis and single vessel bypass grafting of the obtuse marginal. Whilst having chest pain his ECG showed infero-lateral ST depression. Early coronary angiography revealed a new right coronary artery lesion that was not present prior to his cardiac surgery...

A 58-year-old African American female, who had previously undergone a valve-sparing aortic root replacement for a type A dissection, represented 2 months later with a new focal dissection and aneurysm with intramural hematoma just distal to the origin of the left subclavian artery. Since no landing zone distal to the subclavian artery existed, the patient underwent thoracic endovascular aortic repair with laser fenestration-aided stent-graft placement in the left subclavian artery. The patient recovered without complication, and 52 months later, she is doing well with normal renal function and ambulatory status...

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...

The tricuspid valve has historically received less attention than any other cardiac valve with regard to pathophysiology and surgical management. The tricuspid valve is part of a complex functional apparatus that includes the right atrium, right ventricle, and pulmonary circulation. Functional tricuspid regurgitation is the most common tricuspid valve disease and it occurs secondary to dilatation of tricuspid annulus and/or tethering of valve leaflets from right ventricular dilatation and dysfunction. However, recent expansion in the use of right-sided transvenous devices such as pacemakers and implantable defibrillators has been met with a parallel increase in the risk of organic tricuspid disease...
