Transcatheter aortic valve implantation (TAVI) is a recognized therapy for patients with symptomatic severe aortic stenosis (AS). TAVI is superior compared to medical therapy as for mortality in extreme-risk patients, is non-inferior or superior to surgery in high- risk patients and non-inferior to surgery in intermediate-risk patients. However, several limitations affect outcomes after TAVI. Adverse events related to this procedure, like vascular complications, need forpacemaker implantation, paravalvular regurgitation, can be factors limiting TAVI treatment in younger patients at lower risk, as well as uncertainties regarding valve durability...

In case of complete circumferential dissection of the ascending aorta, the dissected flap has the potential to fold backwards, causing several complications. We report two cases of Stanford type A acute aortic dissection (AAD) whose intimal flaps intussuscepted into the left ventricular outflow tract.Case 1: A 41-year-old man with AAD in whom transthoracic echocardiography (TTE) showed the dissected flap as folded back into the left ventricular outflow tract, causing severe aortic regurgitation (AR) with rapidly progressing acute pulmonary edema...

For arrhythmia treatment or sudden cardiac death prevention in hemodialysis patients, there is a frequent need for placement of a cardiac implantable electronic device (pacemaker, implantable cardioverter defibrillator, or cardiac resynchronization device). Leads from a cardiac implantable electronic device can cause central vein stenosis and carry the risk of tricuspid regurgitation or contribute to infective endocarditis. In patients with end-stage kidney disease requiring vascular access and cardiac implantable electronic device, the best strategy is to create an arteriovenous fistula on the contralateral upper limb for a cardiac implantable electronic device and avoidance of central vein catheter...

Evaluation of antiphospholipid antibodies (aPL) and correlation with heart valve abnormalities among patients with systemic lupus erythematosus (SLE). Nested case-control study was conducted with 70 patients with SLE selected from a longitudinal database based on levels of aPL and presence or absence of valve disease by echocardiogram. Valvular abnormalities observed were regurgitation (52), other (14), artificial valves (4), stenosis (2), thickening (2) and no Libman-Sacks endocarditis (0). The mitral valve was the most commonly affected (30 abnormalities), followed by the tricuspid (20 abnormalities)...

OBJECTIVE: Despite excellent long-term results reported for a trans-aortic septal myectomy for hypertrophic obstructive cardiomyopathy (HOCM), surgery for patients with diffuse hypertrophy is very challenging. In addition, a left ventricular outflow obstruction is often aggravated by an abnormal mitral valve and subvalvular apparatus. METHODS: We performed video-assisted minimally invasive trans-mitral septal myectomy procedures in 3 patients with diffuse-type HOCM, who were highly symptomatic despite maximal medical therapy...

BACKGROUND: Right ventricular (RV) dysfunction is recognized as a cardinal prognostic marker in systolic heart failure patients. Conflicting data exist on the interaction of RV function and left ventricular (LV) reverse remodeling after cardiac resynchronization therapy (CRT). This prospective monocentric trial was set up to assess the predictive value of baseline RV function and corresponding RV-pulmonary artery (PA) coupling on LV reverse remodeling after CRT. METHODS: 110 patients with a CRT indication were prospectively enrolled...

INTRODUCTION: The diagnosis of ALCAPA syndrome is sporadic in adulthood, of the limited cases in the literature most are incidental or without symptoms. There is a broad spectrum of clinical manifestations of ALCAPA syndrome however, including sudden cardiac death. CASES: We present herewith a series of 12 consecutive patients with ALCAPA, all diagnosed in adulthood (between 18 and 73 years of age). Five patients developed symptoms (breathlessness) after the fourth decade of life, 3 were undiagnosed despite a history of previous mitral valve repair, one presented with heart failure, one with resuscitated cardiac arrest, whereas two patients were asymptomatic...

OBJECTIVES: Mitral valve (MV) repair is the gold standard for treatment of degenerative mitral regurgitation. A variety of surgical techniques allow surgeons to achieve a high rate of MV repair even with MV diseases of other aetiologies. However, a certain number of repairs fail over time. The aim of this study was to review our single-centre experience of MV re-repair and analyse the mode of repair failure, re-repair safety and efficiency in relation to the initial aetiology. METHODS: Between 1997 and 2015, 91 patients underwent redo MV re-repair...

Advancements in transcatheter technology has increased the number of therapeutic options for patients with tricuspid regurgitation. One category of repair devices attempts to augment leaflet coaptation by either leaflet plication or by functioning as a space occupying device. These include the MitraClip (Abbott, Santa Clara, CA, USA), PASCAL (Edwards Lifesciences, Irvine, CA, USA) and FORMA (Edwards Lifesciences, Irvine, CA, USA) devices. All three have been successfully implanted with promising short term echocardiographic and clinical outcomes...

OBJECTIVES: The Ross procedure has demonstrated excellent results when performed in patients with aortic stenosis or mixed aortic valve disease [aortic stenosis and aortic regurgitation (AR)]. However, due to its reported risk of late reoperation, it is not recommended under current guidelines for patients presenting with bicuspid aortic valve and pure AR. We have analysed our own results in light of this recommendation. METHODS: Between 1993 and 2016, 129 consecutive patients with a mean age of 34...

BACKGROUND: Percutaneous mitral valve edge-to-edge repair (pMVR) with a MitraClip is beneficial for the clinical symptoms of patients irrespective of the ejection fraction (EF). Nevertheless, the consequences on hemodynamics are poorly understood. Therefore, we used data from noninvasive pressure-volume loops to investigate the left ventricular (LV) remodeling of patients after pMVR dependent on their baseline EF. METHODS AND RESULTS: In 130 patients with successful pMVR, the end-diastolic pressure-volume relationship (EDPVR) and end-systolic pressure-volume relationship were estimated noninvasively from echocardiographic data...

BACKGROUND: Quantitative assessment of post-transcatheter aortic valve replacement (TAVR) aortic regurgitation (AR) remains challenging. We developed patient-specific anatomical models with pulsatile flow circuit and investigated factors associated with AR after TAVR. METHODS: Based on pre-procedural computed tomography (CT) data of the six patients who underwent transfemoral TAVR using a 23-mm SAPIEN XT, anatomically and mechanically equivalent aortic valve models were developed...

BACKGROUND: To investigate the feasibility and mid-term results of percutaneous pulmonary valve implantation (PPVI) in patients with conduit free or "native" right ventricular outflow tracts (RVOT). METHODS AND RESULTS: We identified all 18 patients with conduit free or "native" right ventricular outflow tract, who were treated with percutaneous pulmonary valve implantation (PPVI) in our institution. They were divided into two groups - these in whom the central pulmonary artery was used as an anchoring point for the preparation of the landing zone (n=10) for PPVI and these, in whom a pulmonary artery branch was used for this purpose (n=8)...
