INTRODUCTION: Percutaneous balloon aortic valvuloplasty (BAV) has been limited by the risk of complications and restenosis. However, growing use of transcatheter aortic valve implantation (TAVI) has revived interest in this technique. We analyzed the current indications for BAV and outcomes in a single center. METHODS: Acute results and long-term outcomes were analyzed in a retrospective single-center registry of patients undergoing BAV between January 2013 and January 2016...

Acute kidney injury (AKI) after surgery or intervention is an important complication that may impact mortality, morbidity, and health care costs. Endovascular procedures are now performed routinely for a variety of pathologies that were traditionally treated with open surgery because randomized trials comparing endovascular and open surgery have shown at least equally good results and reduced complication and hospitalization rates with endovascular techniques. However, endovascular procedures have been associated with an increased risk for postoperative AKI, predominantly owing to contrast nephrotoxicity...

Background Although transcatheter aortic-valve replacement (TAVR) is an accepted alternative to surgery in patients with severe aortic stenosis who are at high surgical risk, less is known about comparative outcomes among patients with aortic stenosis who are at intermediate surgical risk. Methods We evaluated the clinical outcomes in intermediate-risk patients with severe, symptomatic aortic stenosis in a randomized trial comparing TAVR (performed with the use of a self-expanding prosthesis) with surgical aortic-valve replacement...

Acute afterload mismatch after surgery for mitral regurgitation (MR) with transient left ventricular dysfunction is well known, but not described after transcatheter mitral valve repair with MitraClip, except in functional MR and cardiomyopathy. MitraClip to manage acute severe MR and cardiogenic shock has also been rarely reported. We report here a 77-year-old female who presented with acute severe degenerative MR from a flail posterior leaflet, with cardiogenic shock requiring intra-aortic balloon pump support...

REVIEW
Caroline Bleakley, Mehdi Eskandari, Mark Monaghan
Transcatheter aortic valve implantation (TAVI) was initially proven as an alternative to valve replacement therapy in those beyond established risk thresholds for conventional surgery. With time the technique has been methodically refined and offered to a progressively lower risk cohort, and with this evolution has come that of the significant imaging requirements of valve implantation. This review discusses the role of transoesophageal echocardiography (TOE) in the current TAVI arena, aligning it with that of cardiac computed tomography, and outlining how TOE can be used most effectively both prior to and during TAVI in order to optimise outcomes...

The majority of invasive fungal infections observed in non-neutropenic patients hospitalized in an intensive care unit are caused by Candida spp and current guidelines recommend echinocandins as the first-line treatment. Fungemias caused by filamentous or arthrosporic fungi such as Saprochaete capitata (previously named Geotrichum capitatum) are extremely rare. In fact, invasive infections due to S. capitata have been reported almost exclusively in neutropenic oncohematological patients. In this report, we describe a case of fungemia caused by S...

Introduction. Mural intestinal hematoma (MIH) is an uncommon complication of anticoagulant therapy. Hemorrhagic shock has been rarely reported as a revealing modality. Results. We report two cases of shock induced by mural intestinal hematoma in patients under oral anticoagulant for aortic prosthetic valve and atrial fibrillation. Patients were admitted to the ICU for gastrointestinal tract bleeding associated with hemodynamic instability. After resuscitation, an abdominal CT scan has confirmed the diagnosis showing an extensive hematoma...

Accurate evaluation of trans-aortic valvular pressure gradients is challenging in cases where dual mechanical aortic and mitral valve prostheses are present. Non-invasive Doppler echocardiographic imaging has its limitations due to multiple geometric assumptions. Invasive measurement of trans-valvular gradients with cardiac catheterization can provide further information in patients with two mechanical valves, where simultaneous pressure measurements in the left ventricle and ascending aorta must be obtained...

Apicoaortic conduit surgery is an option for treating severe aortic stenosis. The implanted conduit valve may eventually fail and require replacement; this is usually performed by repeat surgery. Treating the conduit valve with a standard transcatheter heart valve is an option that has become feasible in recent years. We describe a case of a failed 23 mm CE bioprosthesis that was successfully treated with a 23 mm Sapien XT valve as a valve-in-valve procedure. © 2017 Wiley Periodicals, Inc.

A 50-year-old man was admitted with fever and chill sensation 6 months ago. Transthoracic echocardiography (TTE) showed left and right coronary cusp prolapses and a thickened tissue of the aortic curtain. Congestive heart failure due to active infective aortic valve endocarditis was diagnosed, and he underwent aortic valve replacement. The aortic annulus was reconstructed using a glutaraldehydetreated autologous pericardium. Six months after surgery, TTE showed severe aortic regurgitation and saccular change in the aortic annulus...

A right mini-thoracotomy approach may be used for mitral valve repair without compromising clinical outcomes. Compared with conventional sternotomy, there is an increased distance to the cardiac structures from the mini-thoracotomy incision, which makes certain technical acts more demanding. One particular challenge is hemostasis at the antegrade cardioplegia cannula site. We propose a novel technique to remove an antegrade cardioplegia cannula using the COR-KNOT system. This technique negates the need for tying with a knot pusher and reduces the risk of aortic injury and troublesome bleeding...

Transaortic approach represents an alternative variant of transcatheter aortic valve implantation (TAVI) which combines benefits of antegrade transapical approach and high safety profile characteristic of transfemoral approach. This method has substantial advantages over subclavian and transapical approaches in cases of pronounced myocardial hypertrophy, left ventricular dysfunction, thinning of left ventricular wall. We describe here a hybrid intervention with simultaneous coronary artery bypass grafting and TAVI in a patient from high surgical risk group with multivessel coronary artery involvement and critical aortic stenosis...

The present case exemplified the detrimental traits of prosthetic valve endocarditis caused by Propionibacterium acnes. As a baby, the patient had a congenital cardiac defect with truncus arteriosus type I with interrupted aortic arch and open ductus Botalli, and had undergone several operations. However, at 18 months after a Bentall procedure performed 29 years later he presented with major prosthetic dehiscence due to endocarditis. The patient underwent a high-risk reoperation for a re-do Bentall procedure and was treated postoperatively with intravenous antibiotics consisting of vancomycin for five weeks and penicillin and rifampicin each for six weeks...
