Pulmonary valve replacement (PVR) is the most common adult congenital cardiac operation performed. Valve degeneration leading to prosthetic stenosis and/or regurgitation is a long-term risk in this population and may be associated with paravalvular leak (PVL). Complications involving the proximal pulmonary artery, including dissection, are less clearly defined. Herein, we report the case of a 30-year-old patient with a history of multiple pulmonary valve interventions secondary to congenital pulmonic stenosis, who developed dehiscence of a bioprosthetic PVR associated with significant paravalvular leak (PVL) and further complicated by a focal dissection of the proximal pulmonary artery...

Lacosamide is a new-generation antiepileptic drug (AED) most commonly used adjunctively in the setting of partial-onset seizures refractory to traditional therapy. We describe the first case report, to our knowledge, of a patient who developed recurrent, sustained ventricular tachycardia with multiple administrations of lacosamide in an acute setting. A 70-year-old woman with a history significant for valvular heart disease was admitted to the inpatient cardiology service for worsening heart failure. On hospital day 7, she received a bioprosthetic aortic valve...

BACKGROUND: Subclinical leaflet thrombosis of bioprosthetic aortic valves after transcatheter valve replacement (TAVR) and surgical aortic valve replacement (SAVR) has been found with CT imaging. The objective of this study was to report the prevalence of subclinical leaflet thrombosis in surgical and transcatheter aortic valves and the effect of novel oral anticoagulants (NOACs) on the subclinical leaflet thrombosis and subsequent valve haemodynamics and clinical outcomes on the basis of two registries of patients who had CT imaging done after TAVR or SAVR...

OBJECTIVES: We assessed vortex patterns and energy loss in left ventricular flow in patients who underwent mitral valve repair or replacement with bioprosthetic valves. METHODS: Vector flow mapping was performed before and after the procedure in 15 and 17 patients who underwent repair and replacement, respectively. The preprocedure mitral-septal angle was measured in all patients. Relationships between vortex patterns or energy loss change (ELC) and annuloplasty ring or bioprosthetic valve sizes or the effect of mitral leaflet resection in the repair group were statistically analysed...

OBJECTIVES: Valve-sparing operations and root replacement with a biologic composite conduit are viable options in aortic root aneurysm. This study was conceived to compare the early and mid-term results of these 2 procedures. METHODS: From September 2002 to November 2015, 749 consecutive patients underwent either a valve-sparing operation or a root replacement with a biologic composite conduit at 2 institutions. Propensity score matching was used to compare similar cohorts of patients in the overall population and in the ≤ 55 and ≥ 65-year age groups...

Redo aortic valve replacement (AVR) performed simultaneously with left ventricular assist device (LVAD) implantation carries potential for increased mortality rates. Although transcatheter AVR has been used for patients with previous LVAD placement, no literature reports concomitant valve-in-valve transcatheter AVR and LVAD implantation. Our patient had severe aortic prosthetic valve deterioration and advanced heart failure. Given the risks associated with reoperative aortic valve surgery, we chose transcatheter AVR at the time of LVAD implantation...

The AngioVac is a vacuum-based device introduced in 2012 to percutaneously remove undesirable material from the intravascular system. In scattered reports, the AngioVac has been used for removal of device lead vegetations and right-sided thrombi. In this article, we describe three cases of right-sided endocarditis treated with AngioVac: a mobile mass extending from the vena cava into the right atrium, large native tricuspid vegetations, and bioprosthetic tricuspid vegetations. This device shows benefit in reducing vegetation load, decreasing septic lung embolization, and reducing reinfection in active intravenous drug users...

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)...

The use of transcatheter aortic valve replacement (TAVR) as an acute treatment in severe decompensated bioprosthetic aortic valve disease is not well documented. We describe herein a unique case in which valve-in-valve (ViV) TAVR was successfully used as both an emergency salvage therapy and a bridge to definitive fourth reoperative aortic valve replacement (AVR) in a young patient with cardiogenic shock secondary to bioprosthetic aortic valve stenosis who was dependent on veno-arterial extracorporeal membrane oxygenation (VA-ECMO)...

The development of paravalvular leak (PVL) following surgical replacement of an aortic or mitral valve is an uncommon complication with significant morbidity and mortality. Surgical or percutaneous repair of PVL can be technically challenging. We describe the application of intracardiac echocardiography guided 3-dimensional electroanatomic mapping to facilitate PVL closure in a symptomatic patient with a previously placed bioprosthetic mitral valve. © 2017 Wiley Periodicals, Inc.

Transcatheter aortic valve replacement is standard of care for patients with severe aortic stenosis at high risk for surgical aortic valve replacement. Although not intended for treatment of primary aortic insufficiency, several transcatheter aortic valve prostheses have been used to treat patients with severe aortic insufficiency (AI), including patients with left ventricular assist devices (LVAD), in whom significant AI is not uncommon. Similarly, transcatheter valve replacements have been used for valve-in-valve treatment, in the pulmonary, aortic, and mitral positions, either via a retrograde femoral approach or antegrade transseptal approach (mitral valve-in-valve)...

OBJECTIVES: To describe the short-term and long-term outcome in dogs with tricuspid valve dysplasia undergoing tricuspid valve replacement under cardiopulmonary bypass. METHODS: Data were collected from the hospital records of all dogs that had undergone tricuspid valve replacement under cardiopulmonary bypass between 2006 and 2012. Dogs were considered candidates for tricuspid valve replacement if they had severe tricuspid valve regurgitation associated with clinical signs of cardiac compromise...

Hemolytic anemia is a well-recognized complication in patients with left-sided mechanical heart valves. It is rare to see hemolysis with a bioprosthetic valve in the right ventricular outflow tract. We report a 4-year-old-girl with history of truncus arteriosus status-post repair who developed hemolytic anemia as a result of a calcified and obstructed bioprosthetic right ventricular to pulmonary artery-valved conduit. The hemolysis was alleviated by replacing the obstructed conduit with a larger valved conduit...

Percutaneous transcatheter tricuspid balloon valvuloplasty (PTTBV) is an accepted treatment option for symptomatic severe native tricuspid valve stenosis, although surgical tricuspid valve replacement remains the treatment of choice. There have been few reports of successful PTTBV for bioprosthetic tricuspid valve stenosis. We present case reports of 3 patients from our hospital experience. Two of the 3 cases were successful, with lasting clinical improvement, whereas the 3rd patient failed to show a reduction in valve gradient...

BACKGROUND: The unique design of the Freestyle stentless aortic bioprosthesis has led to different mechanisms of failure, particularly leaflet tearing. The aim of this retrospective study was to review the clinical presentation and echocardiographic data of symptomatic patients with leaflet tears and significant aortic regurgitation (AR) following implantation of the Freestyle bioprosthesis. METHODS: Between January 1993 and May 2011, a total of 430 consecutive patients was identified at the authors' institution who had undergone primary aortic valve replacement with a Freestyle stentless aortic bioprosthesis...

Bioprosthetic heart valves (BHVs), derived from glutaraldehyde crosslinked (GLUT) porcine aortic valve leaflets or bovine pericardium (BP), are used to replace defective heart valves. However, valve failure can occur within 12-15 years due to calcification and/or progressive structural degeneration. We present a novel fabrication method that utilizes carbodiimide, neomycin trisulfate, and pentagalloyl glucose crosslinking chemistry (TRI) to better stabilize the extracellular matrix of BP. We demonstrate that TRI-treated BP is more compliant than GLUT-treated BP...

Atrial fibrillation (AF) and valvular heart disease (VHD) frequently coexist and independently increase mortality1. Bioprosthetic valve implantation (surgical or transcatheter), is a common, increasingly utilized treatment for VHD2. Patients with AF and bioprosthetic valves require anticoagulation to prevent thromboembolic events. Non-vitamin K oral anticoagulants (NOACs) are safe and efficacious alternatives to vitamin K antagonists for anticoagulation in AF. However, guidelines recommend against NOACs in patients with bioprosthetic valves, citing a lack of supporting data...
