Delayed aortic regurgitation following Valsalva sinus re-dissection is a well-known complication that can occur at any time after surgery for type-A aortic dissection without root replacement. We describe a case of acute type-A dissection in an 81-year-old lady successfully treated with aortic valve resuspension and ascending aorta replacement with a 28-mm vascular graft. A month later, the patient was readmitted for worsening heart failure and a transthoracic echocardiogram showed severe aortic regurgitation secondary to non-coronary Valsalva sinus re-dissection and non-coronary aortic valve leaflet prolapse also confirmed at computed tomography scan...

A 4 mo old intact male kitten was presented for chronic regurgitation and failure to thrive after weaning to dry food. Esophageal dilatation and severe diffuse proliferative lesions of the esophageal mucosa were found via radiography and esophagoscopy, respectively. Histopathologic examination revealed severe, chronic, diffuse, hyperplastic eosinophilic and mastocytic esophagitis. Eosinophilic infiltrates were prominent, with a mean of 29.8 eosinophils per high power field, supportive of eosinophilic esophagitis (EoE)...

This brief report describes a case of flail anterior tricuspid valve leaflet in a neonate associated with maternal antiphospholipid syndrome. Fetal echocardiography at 27 weeks of gestation showed competent atrioventricular valves with biventricular echogenic chordae. Fetal distress was noted at delivery, and echocardiography showed a flail anterior leaflet of the tricuspid valve with severe regurgitation. Possible causation and implications of maternal antiphospholipid syndrome are discussed.

OBJECTIVE: To evaluate the safety and efficacy of submucosal tunneling endoscopic septum division (STESD) for escophageal diverticulum. METHODS: Clinical data of six consecutive patients with symptomatic esophageal diverticula who received STESD in Endoscopy Center of Zhongshan Hospital, Fudan University from April 2016 to November 2016 were analyzed retrospectively. STESD was performed as following: mucosal entry was made 3 cm from the septum of esophageal diverticulum; submucosal tunnel was created towards the septum; after the satisfactory exposure of the septum, endoscopic division was made down to the bottom of the diverticulum; mucosal closure of the tunnel entry was made...

Bicuspid aortic valve is traditionally considered an innocuous congenital anomaly. Due to a better and widespread availability of non-invasive imaging techniques, it has come to the fore that 30% of these cases develop complications, viz., valve abnormality (aortic regurgitation and stenosis), and aneurysm of aortic root and ascending aorta. Sinus of Valsalva aneurysm is an uncommon complication of bicuspid aortic valve and more so those arising from the left coronary sinus are the rarest. These complications generally occur in the third or fourth decade of life...

We describe herein 2 patients who developed severe mitral stenosis (MS) approximately two decades after a mitral valve repair operation for pure mitral regurgitation (MR) secondary to mitral valve prolapse. This report's purpose is to point out that use of a circumferential mitral annular ring during the repair has the potential to produce a transmitral pressure gradient just like that occurring after mitral valve replacement utilizing a mechanical prosthesis or a bioprosthesis in the mitral position.

As transcatheter aortic valve replacement has become an alternative treatment for patients at high risk for surgical aortic valve replacement, bicuspid aortic valve (BAV) draws our attention again. The reported frequency of BAV was 0.5% to 2% in western population. However, there was no such epidemiologic study in Chinese population. Our study sought to investigate the prevalence and complications of BAV in China by echocardiographic database. A total of 668 cases who were confirmed with BAV, identified from 195,708 echocardiographic records of 157,039 patients in the echocardiographic database of West China Hospital (between June 2008 and June 2012), were analyzed retrospectively...

The PARTNER group recently published a comparison between the latest generation SAPIEN 3 transcatheter aortic valve implantation (TAVI) system (Edwards Lifesciences, Irvine, CA, USA) and surgical aortic valve replacement (SAVR) in intermediate-risk patients, apparently demonstrating superiority of the TAVI and suggesting that TAVI might be the preferred treatment method in this risk class of patients. Nonetheless, assessment of the non-randomized methodology used in this comparison reveals challenges that should be addressed in order to elucidate the validity of the results...

Background Permanent pacemaker implantation after surgical aortic valve replacement depends on patient selection and risk factors for conduction disorders. We aimed to identify risk criteria and obtain a selected group comparable to patients assigned to transcatheter aortic valve implantation. Methods Isolated sutured aortic valve replacements in 994 patients treated from 2007 to 2015 were reviewed. Demographics, hospital stay, preexisting conduction disorders, surgical technique, and etiology in patients with and without permanent pacemaker implantation were compared...

BACKGROUND: Chronic ventricular pacing (VP) is associated with systolic dysfunction in a subset of pediatric patients with heart block and structurally normal hearts. The effect of chronic VP in congenital heart disease is less well understood, specifically in the single-ventricle (SV) population. OBJECTIVE: To determine the longitudinal effect of VP in SV patients. METHODS: SV patients with heart block and dual-chamber pacemakers requiring >50% VP were compared with nonpaced (controls) SV patients matched for age, sex, and SV morphology...

OBJECTIVES: This study aimed to assess the hypothesis that mitral annular disjunction (MAD) is associated with abnormal annular dynamics due to decoupling of annular-ventricular function. BACKGROUND: MAD, defined as a separation between the atrial wall-mitral valve (MV) junction and left ventricular (LV) attachment, is a structural abnormality occurring in MV prolapse (MVP). Few data exist on the 3-dimensional (3D) geometry of MAD and its functional implication...

BACKGROUND: Surgical repair of functional tricuspid regurgitation (FTR) is an increasingly common practice, but annuloplasty suture dehiscence remains a significant problem. Quantitative and mechanistic understanding of annular suture holding strength can support more effective techniques for tricuspid valve device anchoring. METHODS: Suture holding strength of ovine tricuspid annuli (n = 15) was quantified ex vivo by pullout testing at 12 positions around their circumference...

BACKGROUND: Cardiac valve disease is common in patients with end-stage heart failure undergoing left ventricular assist device implantation (LVAD). The aim of this study was to determine if preoperative mitral regurgitation (MR) affects outcomes and hemodynamics in patients after LVAD implantation. METHODS: From March 2006 through May 2015, 238 consecutive patients underwent LVAD implantation. Patient cohorts included less than moderate to severe MR (< moderate-severe, n = 195) and greater than or equal to moderate to severe MR (≥ moderate-severe, n = 43)...

BACKGROUND: Functional mitral regurgitation (MR) can occur in patients with atrial fibrillation (AF) despite having preserved left ventricular (LV) systolic function. This MR is known as atrial functional MR. The aim of this study was to clarify the mechanism of atrial functional MR using real-time three-dimensional transesophageal echocardiography (3DTEE). METHODS: Sixty patients underwent transthoracic echocardiography and 3DTEE: 16 patients with AF and significant non-organic MR and preserved LV ejection fraction (>50%) constituted the AF-MR group, 20 patients with AF and no significant MR formed the AF-NSMR group, and 24 normal subjects comprised the control group...

PURPOSE: Device management of hemodynamic instability due to acute aortic regurgitation is not available. A novel, catheter-based, temporary aortic valve (TAV) has been in development. Early prototypes (balloon-based TAV) have undergone proof-of-concept studies in mathematical, bench and animal models. The redesigned membrane-based TAV prototype is evaluated in a rabbit model of acute severe aortic regurgitation. METHODS: Acute aortic regurgitation was simulated by deploying a self-expanding endovascular stent across the aortic annulus...

BACKGROUND: Optimal management of aortic root in type A aortic dissection (AAD) is controversial. To determine the most appropriate strategy, we studied the late outcomes after conservative repair of aortic root. METHODS: 234 AAD patients (mean age 68 ± 12 years) underwent surgical repair using supracommissural replacement (SCR) for aortic root reconstruction from 1989 to 2014. Ascending aortic replacement or hemi-arch replacement was performed in 180 patients (non-arch group), whereas total arch replacement (TAR) was performed in 54 patients...

Cardiac amyloidosis may occur in any type of systemic amyloidosis. The clinical picture is often characterized by restrictive cardiomyopathy. We report the case of a 41-year-old female patient admitted to the Department of Cardiology with clinical signs of right heart failure: congested jugular veins, hepatomegaly, peripheral edema, ascites associated with atrial fibrillation, low values of arterial blood pressure and oliguria. Echocardiographic findings were helpful for the diagnosis of cardiac amyloidosis: enlarged atrial cavities, normal size ventricles, thickened ventricular septum and posterior left ventricle wall with normal left ventricular ejection fraction, mitral and tricuspid regurgitation...
