Herein is presented the case of an 83-year-old male patient in cardiogenic shock with acute aortic regurgitation that occurred six years after aortic valve replacement (AVR) with a 23 mm Trifecta™ valve. Prosthesis endocarditis was initially suspected because of a floating structure attached to the aortic valve that was visible on echocardiography. Emergency redo-AVR surgery was performed, but no signs of endocarditis were found intraoperatively. Hence, cusp tearing of the implanted bioprosthesis was considered to be the reason for the severe aortic regurgitation...

BACKGROUND: Despite the limited durability of biological aortic valves, increasing numbers of younger patients are choosing to receive them, due mainly to the lack of a need for permanent anticoagulation. Few data exist, however, regarding the outcomes of valve replacement in patients aged <55 years, and additional data are required in this patient population. METHODS: Between 1993 and 2014, at the authors' institution, a total of 448 patients (237 males, 101 females; mean age 45...

A rare case of mitral stenosis after mitral valve repair for non-rheumatic mitral regurgitation is presented. An 81-year-old woman who had undergone mitral valve repair using an annuloplasty ring 12 years earlier, was referred to our hospital because of dyspnea during exertion. As echocardiography revealed severe mitral stenosis, and redo surgery was carried out. During the surgery, fibrous tissue covered the annuloplasty ring and extended onto both leaflets of the mitral valve, which narrowed its orifice, by rendering the leaflets stiff and immobile...

Although nonstructural dysfunction of a bioprosthesis caused by pannus formation or native valve attachment has been well described, structural valve deterioration( SVD) caused by calcification or tear of a bioprosthesis, especially a bovine pericardial valve, is very rare in the tricuspid position. We report a case of redo tricuspid valve surgery for SVD 14 years after tricuspid valve replacement( TVR) using a Carpentier-Edwards Perimount (CEP) pericardial valve. A 71-year-old woman was referred to our hospital because of exertional dyspnea and pre-syncope...

BACKGROUND AND AIM OF THE STUDY: The replacement of a failed composite valve graft is technically more demanding and is associated with increased morbidity and mortality. We present our technique and outcomes for reoperations for composite graft failures. METHODS: Between September 2011 and June 2017, 14 patients underwent a redo composite graft replacement. Twelve patients (85.7%) were male, and mean age was 58.4 years ± 12 standard deviation (SD). One patient had two previous root replacements...

The Trifecta aortic valve has excellent hemodynamic performance as result of an expansive valve design with a bovine pericardial sheet externally mounted on a titanium stent. We report two cases of early Trifecta valve degeneration, both caused by partial rupture of one of the leaflet cusps three and four years post-implant. Post discharge, both patients had routinely performed echocardiography check-ups, without signs of valve failure. Transesophageal echocardiography performed while emergency hospital readmission due to severe dyspnea revealed transvalvular aortic regurgitation without signs of endocarditis...

Pericardial effusion after midline cardiac surgery may be transudative or exudative. The exudative infective or haemorrhagic variety requires early surgical intervention. However there are rare cases of collections like chylomediastinum which should be ruled out. Their low incidence prompts to establish protocol for evaluating postoperative pericardial collections, which includes echocardiography and biochemical analysis of aspirate. The same is important from the perspective of management as chylopericardium may be successfully managed without surgical intervention by aspiration, pig tail insertion, dietary and medical management, which we demonstrate through our rare case which occurred after midline double valve replacement...

We report a case of ascending aortic aneurysm repair and redo aortic valve replacement with a bioprosthesis 44 years after aortic valve replacement with a Starr-Edwards metal caged-ball prosthesis. The patient presented with a moderately stenotic caged-ball valve and a 50-mm ascending aortic aneurysm on a routine follow-up transthoracic echocardiography. We replaced the valve with a bioprosthesis at the time of aortic repair as the patient wished to stop anticoagulation therapy. Intraoperatively, we found that the cloth covering of the cage was nearly completely destroyed...

OBJECTIVES: Little data are available with regard to valve selections in redo valvular surgery. We investigated the impact of valve types on late outcomes after redo mitral valve replacement (MVR). METHODS: We retrospectively reviewed 66 patients aged 50-69 (mean age 62.2 ± 5.1)  years who underwent redo MVR over the past 25 years. In redo MVR, 46 (69.7%) redo procedures were the 1st redo valvular surgeries, 16 (24.2%) were 2nd redos, 3 (4.5%) were 3rd redos and 1 was a 4th (1...

OBJECTIVES: Favourable outcomes with mitral annuloplasty have been achieved with transapical cardioscopic (TAC) surgery in a survival animal model. In addition, experimental TAC on a non-survival animal model also showed adequate access to remove the native mitral valve and implant a prosthetic valve, but the surgical procedure took a long time and lacked follow-up data. The goal of this study was to develop a clinically translatable TAC mitral valve replacement (MVR) procedure using technical and instrumental refinements to reduce the surgical time and to evaluate functional recovery and short-term durability using a survival porcine model...

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...

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...

OBJECTIVE: To assess the results of catheter-based and surgical reintervention in primary mitral regurgitation (PMR) after failed MitraClip therapy. METHODS: We report on 21 consecutive symptomatic patients with PMR (median age 78 years) who underwent either repeat MitraClip therapy (n=7) or mitral valve surgery (n=14) after failure of the index procedure with 1-2 MitraClip implantations. At the time of reinterventions, 193 [IQR: 32 to 622] days after index procedure, patients had recurrent or persistent grade 3 MR...

Bioprosthetic aortic valves have been used with increasing frequency over the past two decades, often in relatively young patients who may eventually require aortic valve re-operations due to degeneration of the bioprosthesis. Growing experience with minimally invasive aortic valve replacement has prompted surgeons to use minimally invasive approaches also with redo operations for replacement of the aortic valve.  This tutorial describes the operative steps for a minimally invasive redo replacement of the aortic valve through an upper ministernotomy...

BACKGROUND: Surgical ablation (SA) for atrial fibrillation (AF) concomitant to mitral valve repair/replacement (MVRR) improves longitudinal sinus rhythm. However, the risk of adding SA remains a clinical question. This study examined whether the addition of contemporary SA for AF has an impact on operative outcomes. METHODS: The study cohort included 88,765 MVRR patients with or without SA, coronary artery bypass grafting (CABG), septal defect, and tricuspid repair in The Society of Thoracic Surgeons Database between 2011 and 2014...

Because of its favourable haemodynamic characteristics and easy implantability, Mitroflow aortic valve bioprosthesis has been the valve of choice for many surgeons in patients with small aortic annulus. Disappointingly, early structural valve deterioration and high transvalvular gradients have been reported mostly in older patients with small prostheses. Reimplanting a new stented prosthesis sutured in a narrow and damaged annulus is technically challenging and demanding mainly in high-risk patients. Valve-in-valve transcatheter aortic valve implantation has been proposed as a viable option; however, it presents significant limitations because of residual high transprosthetic pressure gradients and risk of coronary occlusion...
