The aims of this study are to evaluate the long-term outcomes of double valve replacement (aortic and mitral valves) and to investigate the determinants of late tricuspid regurgitation (TR). A total of 239 consecutive patients who underwent double valve replacement were enrolled. Valve pathology was rheumatic in 86.6% (207/239) and degenerative in 13.4% (32/239) of patients. Among these patients, 116 patients underwent concomitant tricuspid annuloplasty, and follow-up was completed for all 239 patients (mean = 7...

OBJECTIVE: Current techniques for mitral valve repair (MVR) in Barlow's disease require high level of surgical expertise due to a complex anatomy. A novel and simple standardized technique that particularly considers the pathological changes of the mitral valve in Barlow's disease has been developed. METHODS: Between 2009 and 2013, 22 patients underwent minimally invasive MVR for Barlow's disease and severe mitral regurgitation (MR). A simple, standardized technique was applied, including resection of P2 segment of posterior mitral leaflet (PML) with preservation of the shortest chordae, transfer of the preserved chordae to A2, and implantation of a semi-rigid open ring...

OBJECTIVES: To investigate short- and long-term outcomes of a conservative decalcification approach in mitral valve replacement (MVR) surgery in the presence of mitral annulus calcification (MAC). METHODS: Of the 1038 patients who underwent MVR, 133 (13%) had significant MAC with at least 30% of the annular circumference heavily calcified. In most patients, the surgical approach to MAC included conservative decalcification, supra-annular prosthesis implantation and insertion of a pericardial patch between the MV annulus and the prosthesis...

BACKGROUND: Little is known about baseline diastolic dysfunction and changes in diastolic dysfunction grade after transcatheter aortic valve replacement (TAVR) for aortic stenosis (AS) and its impact on overall outcomes. The aim of this study was to describe baseline diastolic dysfunction and changes in diastolic dysfunction grade that occur with TAVR and their relationship to mortality and rehospitalization. METHODS: This was a single-center study evaluating all TAVRs from January 2012 to June 2014...

An 84-year-old man presented 5 years following bioprosthetic mitral valve replacement with three months of worsening dyspnea on exertion. A new mitral stenosis murmur was noted on physical examination, and an electrocardiogram revealed newly recognized atrial fibrillation. Severe mitral stenosis (mean gradient = 13 mmHg) was confirmed by transthoracic echocardiography. Transesophageal echocardiography revealed markedly thickened mitral bioprosthetic leaflets with limited mobility, and a massive left atrial thrombus (> 4 cm in diameter) (see Figures 1A-D, and video files 1-4)...

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...

AIM: Patient-prosthesis mismatch (PPM) is a common occurrence in aortic valve surgery. Even the discussions about the impact of this phenomenon on the results of aortic valve surgery, the management of this problem remain one of the main topics in this kind of surgery. One of the ways of a solution is aortic annulus enlargement. The main topic of this study is to evaluate the early and longterm results of this technique in our country. METHODS: During the period January 2010 -January 2015, 641 patients performed aortic valve surgery...

BACKGROUND: Surgical mitral valve repair is the gold standard for treatment of mitral regurgitation. Recently, the transcatheter treatment of mitral regurgitation with the MitraClip(®) device (Abbot Vascular Structural Heart, Menlo Park, CA) has demonstrated promising results in treating patients not amenable for surgical correction of mitral valve regurgitation. Most patients reported in the literature requiring surgical bailout after MitraClip treatment presented with residual or recurrent mitral valve regurgitation...

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiovascular disease characterized by a thickened non-dilated ventricle in the absence of another cardiac or systemic condition. Its most important hemodynamic consequence is left ventricular outflow tract (LVOT) obstruction. The primary management strategy of this condition is surgical septal myectomy, but an acceptable alternative treatment in patients who are not suitable for (or who refuse) surgery is alcohol septal ablation (ASA). However, in patients with unfavorable coronary anatomy which precludes ASA (i...

OBJECTIVES: To evaluate the outcomes of the early experience of percutaneous alcohol septal ablation in patients with severe left ventricular outflow tract (LVOT) obstruction post transcatheter mitral valve replacement (TMVR). BACKGROUND: Severe LVOT obstruction with hemodynamic compromise is a complication of TMVR associated with high mortality. Percutaneous alcohol septal ablation has recently been described as a therapeutic option in this setting. METHODS: Multicenter retrospective review of clinical outcomes of patients undergoing alcohol septal ablation to treat LVOT obstruction after TMVR for severe mitral stenosis with severe mitral annular calcification...

A Chinese woman was admitted to our hospital because of syncope. Transthoracic echocardiography revealed a hypertrophic basal interventricular septum of 15 mm with a sharp angle protruding into the left ventricular outflow tract. Moreover, an anomalous anterolateral papillary muscle (maximum width of 11 mm) was inserted into the left ventricular outflow tract, with short chordae tendineae connecting both basal interventricular septum and anterior leaflet of the mitral valve. All of these abnormalities resulted in a left ventricular outflow gradient of 136 mmHg...

Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract. The Morrow operation has remained the gold standard for surgically treating this pathology...

INTRODUCTION: Chordal replacement (Chord MVr) for isolated posterior mitral valve prolapse allows for preservation of the native mitral valve apparatus. The potential benefits of this approach, as compared with leaflet resection (Resection), are not clearly defined. EVIDENCE ACQUISITION: A systematic review and meta-analysis was conducted on operative, clinical, and echocardiographic outcomes. Risk ratios (RR) were calculated by the Mantel-Haenszel method under a fixed or random effects model, as appropriate...

INTRODUCTION: The treatment of complex prosthetic valve endocarditis (PVE) with aortic root abscess remains a surgical challenge. Several studies support the use of biological tissues to minimize the risk of recurrent infection. We present our initial surgical experience with the use of an aortic xenograft conduit for aortic valve and root replacement. METHODS: Between October 2013 and August 2015, 15 xenograft bioconduits were implanted for complex PVE with abscess (13...

AIMS: Concomitant severe calcific aortic and mitral stenosis is a relatively uncommon but very challenging valvular heart disease to manage. We sought to evaluate the feasibility of a fully percutaneous approach to replace both stenotic native mitral and aortic valves using SAPIEN 3 valves. METHODS AND RESULTS: An 87-year-old woman with chronic kidney disease stage 3, pul-monary hypertension, chronic obstructive pulmonary disease, a permanent pacemaker, and atrial fibrillation was referred with Class III heart failure symptoms...

BACKGROUND: The change in the level of NT-Pro-BNP (N-terminal Pro-Brain Natriuretic Peptide) is now considered as a reflection of the hemodynamic alterations and its circulatory reductions reported early after successful PTMC (percutaneous transvenous mitral commissurotomy). The present study aims to assess the change in the level of NT-Pro BNP following PTMC in patients with mitral stenosis and also to determine the association between circulatory NT-Pro BNP reduction and post-PTMC echocardiography parameters...

INTRODUCTION: Partial resection of the septal muscle is a well-established and effective method of surgical treatment for patients with hypertrophic obstructive cardiomyopathy (HOCM). The procedure is characterized by a low operative mortality rate and long-term clinical improvement that has been confirmed in numerous publications. Mitral insufficiency in patients with HOCM is mostly functional due to the effect of systolic anterior motion (SAM). AIM: To present the early results of surgical treatment provided to HOCM patients and to compare the effectiveness of two surgical procedures: isolated myectomy and myectomy combined with mitral valve replacement...

OBJECTIVES: Current nonpharmacological therapies for symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM), including septal myectomy and alcohol septal ablation (ASA), carry significant risks for serious cardiac conduction abnormalities. We present a review of the currently available published data regarding the novel use of the relatively low-risk MitraClip® system in the treatment of symptomatic patients. METHODS: Data were collected from 4 separate studies on the use of the MitraClip on 15 symptomatic HOCM patients with systolic anterior motion (SAM) of the mitral valve apparatus...

We report the case of early recurrence of Tako-Tsubo cardiomyopathy in an elderly woman with amyotrophic lateral sclerosis triggered by different stressors. A first episode with typical apical ballooning was anticipated by an emotional stress; a second, characterized by systolic anterior motion of the mitral valve associated with mitral regurgitation and severe intra-ventricular gradient, was precipitated by surgical stress and hypovolemia. We therefore hypothesize both a possible link between amyotrophic lateral sclerosis and Tako-Tsubo cardiomyopathy, and between different stressors and different Tako-Tsubo patterns...
