PURPOSE Significant late-onset tricuspid regurgitation (TR) is unfortunately common after double valve replacement (DVR); however, its underlying factors remain undefined. We evaluated the effect of aortic patient-prosthesis mismatch (PPM) on late-onset TR and clinical outcomes after DVR. MATERIALS AND METHODS Of the 2392 consecutive patients who underwent aortic valve replacement between Jan...

Transcatheter aortic valve implantation (TAVI) is a recently developed surgical technique to treat symptomatic aortic valve stenosis in elderly and high-risk patients (Eltchaninoff et al., 2008; Ferrari & von Segesser, 2010). Compared to the standard aortic valve replacement surgery, the TAVI limits the surgical access to either a small minithoracotomy (transapical TAVI) or femoral approach (tr...

OBJECTIVES With the increase in life expectancy occurred in recent decades, it has been noted the concomitant increase in the prevalence of aortic stenosis and degenerative disease of atherosclerotic coronary artery. This study aims to evaluate the influence of atherosclerotic coronary artery disease in patients with critical aortic stenosis undergoing isolated or combined implant valve prosthe...

OBJECTIVES Choice of prosthesis type in middle-aged patients undergoing aortic valve replacement (AVR) is still debated. The aim of this study is to compare long-term follow-up results in middle-aged patients who underwent isolated AVR with a biological or mechanical prosthesis. METHODS A retrospective analysis of a single-centre database was performed to identify patients aged between 55 and...

RECENT REPORTS of postoperative clinical and cardiac catheterization studies in patients after replacement of their aortic valves with a ball-valve prosthesis have included adequate clinical and hemodynamic measurements both at rest and during exercise.'-6 There is, however, little information regarding the competency of these valves as determined angiographically, since aortic root cineangiogr...

UNLABELLED Transcatheter aortic valve implantation (TAVI) is currently considered an acceptable alternative for the treatment of patients with severe aortic stenosis and a high perioperative risk or a contraindication for open surgery. The benefit of TAVI significantly outweighs the risk of the procedure in patients requiring treatment that are not suitable for open surgery, and leads to a lowe...

INTRODUCTION Approximately 60 000 prosthetic valves are implanted annually in the USA. The risk of prosthesis dysfunction ranges from 0.1% to 4% per year. Prosthesis valve dysfunction is usually caused by a thrombus obstructing the prosthetic discs. However, 10% of prosthetic valves are dysfunctional due to pannus formation, and 12% of prostheses are damaged by both fibrinous and thrombotic com...

Transcatheter aortic valve implantation is being established as an alternative treatment for some patients with symptomatic severe aortic stenosis who are not considered suitable for surgical aortic valve replacement because of prohibitive surgical risk.1–3 One of the potential complications is complete atrioventricular block requiring definitive pacemaker implantation. This complication occurs...

We know that the mitroaortic endocarditis is one of the worse and risky surgical situation, particularly when it happens in patients previously operated and whether is involved the mitroaortic continuity and atrial septum. In this paper we describe here the surgical solution applied to one patient. We present here a 79-year old man with symptoms of fever, leukocytosis, confusional state, vomits...

Intermittent dysfunction of prosthetic aortic valve is a rare but life-threatening condition that may be difficult to recognize. Here, we present a case of 64-year-old man with a history of bicuspid aortic valve that had been replaced with a Medtronic-Hall prosthesis 15 years earlier. Until his current illness, he was fit, with good function of the valve and well maintained anticoagulation. Aft...
