BACKGROUND: Twenty percent of patients born with congenital heart disease present with right ventricular outflow tract abnormalities. These patients require multiple surgical procedures in their lifetime. Transcatheter pulmonary valve replacement (TPVR) has become a viable alternative to conventional pulmonary valve and right ventricular outflow tract surgery in pediatric and adult populations. In this retrospective review, we analyze the perioperative management of adult patients who underwent TPVR in our center...

Transcatheter aortic valve implantation (TAVI) is an effective and less invasive treatment for the increasing population of individuals with severe aortic stenosis (AS). Echocardiography is crucial in the assessment of AS patients from pre- to post-procedure. Transthoracic echocardiography (TTE) may be used to assess patient suitability for TAVI, as well as evaluate the severity of AS, the aortic valve complex, aortic valve morphology, mitral regurgitation (MR), and left ventricular function. Transesophageal echocardiography (TEE) is usually used as an intra-procedural monitoring tool to provide feedback during the procedure, to assess prosthetic valve function, and to detect complications rapidly before and after balloon aortic valvuloplasty (BAV) or transcatheter heart valve (THV) deployment...

AIMS: We compared thromboembolic (TE) and bleeding risks in patients with atrial fibrillation (AF) according to the new 'Evaluated Heartvalves, Rheumatic or Artificial' (EHRA) valve classification. METHODS: Patients were divided into 3 categories: (i) EHRA type 1 corresponds to the previous 'valvular' AF patients, with either rheumatic mitral valve stenosis or mechanical prosthetic heart valves; (ii) EHRA type 2 includes AF patients with other valvular heart disease (VHD) and valve bioprosthesis or repair; and (iii) 'non-VHD controls' i...

OBJECTIVE: Calcific aortic valve disease (CAVD) is a major cause of aortic stenosis (AS) and cardiac insufficiency. Patients with type II diabetes mellitus (T2DM) are at heightened risk for CAVD, and their valves have greater calcification than nondiabetic valves. No drugs to prevent or treat CAVD exist, and animal models that might help identify therapeutic targets are sorely lacking. To develop an animal model mimicking the structural and functional features of CAVD in people with T2DM, we tested a diabetogenic, procalcific diet and its effect on the incidence and severity of CAVD and AS in the, LDLr-/- ApoB100/100 mouse model...

IMPORTANCE: Spreader grafts are commonly used for nasal valve stenosis. There is debate among practitioners regarding the optimal approach for spreader graft placement. OBJECTIVE: This study aimed to determine whether an endonasal spreader graft placement leads to equivalent postoperative outcomes using a standardized nasal obstruction symptom score and whether there is a significant difference in operative time between the 2 approaches. DESIGN: A retrospective review of functional rhinoplasties by a single facial plastic surgeon over a 2-year period was conducted...

BACKGROUND : Comparative echocardiographic data on transcatheter aortic valve replacement systems from randomized trials are limited. The REPRISE III trial (Repositionable Percutaneous Replacement of Stenotic Aortic Valve through Implantation of Lotus Valve System - Randomized Clinical Evaluation) is a multicenter, randomized comparison of a mechanically expanded (Lotus) versus self-expanding (CoreValve) transcatheter aortic valve replacement device. This analysis rigorously assesses Doppler-derived valve hemodynamics and the impact on outcomes at 1 year in patients with extreme/high surgical risk treated with Lotus and CoreValve from REPRISE III...

BACKGROUND: Mitral stenosis may present with decompensated heart failure during pregnancy. Many patients do have advanced sub valve disease and present late with decompensated state. The outcomes of balloon mitral valvuloplasty (BMV) in such advanced sub valve disease with severe heart failure in pregnancy has not been specifically studied till now. METHODS: A descriptive study looking at the immediate and long-term outcomes of pregnant patients with MS who presented with severe heart failure and sub valve disease who had undergone BMV...

We herein report anesthetic management during aortic valve replacement for aortic valve regurgitation in a patient with adult mucopolysaccharidosis type II (MPS type 2) (Hunter syndrome). This disorder is rare and related to the accumulation of a mucopolysaccharide in lysosomes. It affects various organs, including the airways, heart, and central nerves. In children with MPS type 2, the risk of airway obstruction during anesthesia/sedation is high, and the degree of difficulty increases with aging. The patient described herein was a 33-year-old male without mental retardation...

OBJECTIVES: Anomalous aortic origin of a coronary artery (AAOCA) from the opposite sinus of Valsalva is a rare cardiac anomaly associated with sudden cardiac death (SCD). Single-center studies describe surgical repair as safe, although medium- and long-term effects on symptoms and risk of SCD remain unknown. We sought to describe outcomes of surgical repair of AAOCA. METHODS: We reviewed institutional records for patients who underwent AAOCA repair, from 2001 to 2016, at 2 affiliated institutions...

INTRODUCTION: Aortic stenosis is a common condition among older adults that can be associated with dangerous outcomes, due to both the disease itself and its influence on other conditions. OBJECTIVE: This review provides an evidence-based summary of the current emergency department (ED) evaluation and management of aortic stenosis. DISCUSSION: Aortic stenosis refers to significant narrowing of the aortic valve and can be caused by calcific disease, congenital causes, or rheumatic valvular disease...

Transcatheter aortic valve implantation (TAVI) is associated with acute kidney injury (AKI), but can also improve the kidney function (IKF). We assessed the effects of kidney function changes in relation to baseline kidney function on 2-year clinical outcomes after TAVI. In total, 639 consecutive patients with aortic stenosis who underwent TAVI were stratified into 3 groups according to the ratio of serum creatinine post- to pre-TAVI: IKF (≤0.80; n = 95 [15%]), stable kidney function (0.80 to 1.5; n = 477 [75%]), and AKI (≥1...

BACKGROUND: Atrial fibrillation (AF) can occur even after the correction of mitral valve (MV) pathology in patients who have pre-operative sinus rhythm and undergo MV surgery. However, the factors associated with the occurrence of AF after MV surgery are still unclear. The aim of this retrospective study was to investigate the factors determining the occurrence of permanent AF after MV surgery in patients with preoperative sinus rhythm who underwent MV surgery. METHODS: Four hundred and forty-two patients (mean age 46 ± 12, 190 men) who underwent MV surgery and sinus rhythm were investigated retrospectively...

OBJECTIVE: With the introduction of the latest generation Sapien 3 transcatheter aortic valve, there has been a reduction in the usage of transapical (TA) approach for TAVRs in many centers. However, despite the smaller sheath size and more stream-lined delivery system, vascular complications continue to occur, especially in patients with peripheral vascular disease. Thus, our institution has maintained a stringent TA protocol aiming to prevent these complications. We hypothesize that this protocol has helped to reduce vascular complications and improve outcomes at our institution even in the Sapien 3 era...

AIM: Two-dimensional, transthoracic echocardiography does not account for the noncircular anatomy of the left ventricular outflow tract (LVOT) and may therefore underestimate LVOT area. Fusion of computed tomography (CT)-derived LVOT area and Doppler-derived flow data has been proposed to improve assessment of aortic valve area (AVA) and classification of aortic stenosis severity. For hemodynamic reasons, effective AVA has to be smaller than anatomic AVA. The aim of the study was to test the "fusion approach" by comparing effective CT-derived AVA with anatomic AVA from CT planimetry...

OBJECTIVES: We assessed the transventricular placement of porcine small intestinal submucosa (SIS) stent valves in a juvenile sheep model at the 3-month follow-up evaluation. METHODS: We constructed a pulmonary stent valve by suturing a porcine SIS bicuspid valve into a bell-shaped 'Z' nitinol stent and implanted 7 SIS stent valves transventricularly in the pulmonary position in 7 sheep. The function of the stent valves was assessed using a pulsatile flow simulation system in vitro...

BACKGROUND: Evolut-R 34 mm (received CE mark in January 2017) and Sapien-3 29 mm are the only options for transcatheter aortic valve replacement (TAVR) in patients with annulus ≥26 mm. We compared the short-term outcomes of these valves in these patients. METHODS: Data was collected prospectively from consecutive patients with severe aortic stenosis and annulus diameter larger than 26 mm treated by femoral approach TAVR. RESULTS: Between February 1, 2014 to August 19, 2017 Sapien-3 29 mm was implanted in 55 and Evolut-R 34 mm in 37 consecutive patients...
