Bicuspid Aortic Valve: An Update in Morphology, Genetics, Biomarker, Complications, Imaging Diagnosis and Treatment.

Front Physiol 2018 30;9:1921. Epub 2019 Jan 30.

Department of Ultrasound, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

The bicuspid aortic valve, a kind of heart disease that comes from parents, has been paid attention around the world. Although most bicuspid aortic valve (BAV) patients will suffer from some complications including aortic stenosis, aortic regurgitation, endocarditis, and heart dysfunction in the late stage of the disease, there is none symptom in the childhood, which restrains us to diagnose and treatment in the onset phase of BAV. Hemodynamic abnormalities induced by the malformations of the valves in BAV patients for a long time will cause BAV-associated aortopathy: including progress aortic dilation, aneurysm, dissection and rupture, cardiac cyst and even sudden death.

Biventricular repair after the hybrid Norwood procedure.

Eur J Cardiothorac Surg 2019 Feb 8. Epub 2019 Feb 8.

Department of Thoracic Surgery, Leiden University Medical Center, Leiden, Netherlands.

Objectives: We analysed the outcomes of patients undergoing biventricular repair (BVR) after an initial hybrid Norwood approach as a salvage procedure in extremely sick infants; or as the initial palliation in patients with uncertain feasibility of single-stage BVR due to severe left ventricular outflow tract obstruction; or as part of a left ventricle (LV) recruitment strategy in patients with borderline LVs.

Methods: Between September 2010 and July 2018, 26 patients underwent BVR after initial hybrid palliation at a median age of 13 days. The rationale for the hybrid approach was to promote the growth of the LV in 10 patients and that of the left ventricular outflow tract and/or aortic valve in 12 patients and to be a salvage procedure in 4 patients.

Transcatheter Aortic Valve Replacement and Cardiac Resynchronization Therapy in Cancer-Related Cardiotoxicity.

J Cardiovasc Echogr 2018 Oct-Dec;28(4):233-235

Department of Cardiology, Monaldi Hospital, AORN dei Colli, Naples, Italy.

Cardiotoxicity related to antineoplastic agents is a rising and growing issue, therefore early recognition and prompt management can impact on the overall prognosis of cancer patients. We report the case of a 70-year-old woman without cardiovascular risk factors, with a medical history of non-Hodgkin lymphoma and chronic myeloid leukemia treated with chemotherapy and radiotherapy, who underwent transcatheter aortic valve replacement for severe aortic stenosis and cardiac resynchronization therapy for further development of complete left bundle branch block, with a significant improvement of her functional status and left ventricle systolic function in a long-term follow-up.

Effect of preoperative low serum albumin on postoperative complications and early mortality in patients undergoing transcatheter aortic valve replacement.

J Thorac Dis 2018 Dec;10(12):6763-6770

Department of Cardiothoracic Surgery, Heartcenter, Heartcenter, University of Cologne, Cologne, Germany.

Background: Patients undergoing transcatheter aortic valve replacement (TAVR) are mostly elderly patients with substantial comorbidities. Established risk scores are not validated for TAVR and collectives with elderly patients making periprocedural risk stratification difficult. Serum albumin is known to be an indicator for malnutrition and frailty and is simple to measure, independent of physician's bias. Read More

Bronchial compression as adverse effect of right pulmonary artery stenting in a patient with truncus arteriosus communis and interrupted aortic arch.

Ann Pediatr Cardiol 2019 Jan-Apr;12(1):66-68

Department of Pediatrics, East Carolina University 115 Heart Drive Greenville, NC 27834, USA.

Aortic arch obstruction and bronchial compression are possible postoperative complications in patients with truncus arteriosus communis (TAC) with interrupted aortic arch (IAA). We present a case of bronchial compression as adverse effect of right pulmonary artery (PA) stenting in an infant with TAC (Type 4A)-IAA (Type B) repair. Due to growth potential, self-expandable metal stent was applied for postoperative proximal right PA stenosis, which caused bronchial compression. Read More

Outcomes of Transcatheter Aortic Valve Implantation in Patients with Cirrhosis.

Int Heart J 2019 Feb 8. Epub 2019 Feb 8.

Department of Cardiology, Sakakibara Heart Institute.

Cirrhosis is a significant adverse factor of cardiac surgeries. Transcatheter aortic valve implantation (TAVI) has evolved as a less invasive therapy for aortic stenosis, whereas detailed case analysis of TAVI in cirrhotic patients is limited.Among 444 consecutive patients who underwent TAVI in the Sakakibara Heart Institute between October 2013 and January 2018, we retrospectively reviewed 11 patients (2.

Predictive Roles of Neutrophil-to-Lymphocyte Ratio and C-Reactive Protein in Patients with Calcific Aortic Valve Disease.

Int Heart J 2019 Feb 8. Epub 2019 Feb 8.

Department of Cardiovascular Surgery, Shandong Provincial Hospital Affiliated to Shandong University.

The neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) are emerging indirect blood markers to roughly reflect the inflammation level in our body while some pathological changes occurring in aortic valve tissue. Few recent studies demonstrated that NLR is related to calcific aortic valve disease (CAVD). However, the extent of the relationship between them and the impact of CRP on CAVD are not clear.

Prevalence and predictors of coronary artery disease in patients undergoing carotid artery stenting.

Coron Artery Dis 2019 Feb 11. Epub 2019 Feb 11.

Department of Vascular Surgery and Endovascular Interventions, John Paul II Hospital.

Introduction: A relationship between carotid stenosis and coronary arterial disease (CAD) is widely accepted; however, data on the exact prevalence of coronary disease in patients with severe carotid stenosis are lacking. Information on the prevalence and predictors of CAD among these patients could impact diagnostic and treatment approaches.

Aim: The primary aim of this study was to determine the prevalence of significant CAD among patients referred for carotid artery revascularization. Read More

Biventricular Increases in Mitochondrial Fission Mediator (MiD51) and Proglycolytic Pyruvate Kinase (PKM2) Isoform in Experimental Group 2 Pulmonary Hypertension-Novel Mitochondrial Abnormalities.

Front Cardiovasc Med 2018 25;5:195. Epub 2019 Jan 25.

Department of Medicine, Queen's University, Kingston, ON, Canada.

Group 2 pulmonary hypertension (PH), defined as a mean pulmonary arterial pressure ≥25 mmHg with elevated pulmonary capillary wedge pressure >15 mmHg, has no approved therapy and patients often die from right ventricular failure (RVF). Alterations in mitochondrial metabolism, notably impaired glucose oxidation, and increased mitochondrial fission, contribute to right ventricle (RV) dysfunction in PH. We hypothesized that the impairment of RV and left ventricular (LV) function in group 2 PH results in part from a proglycolytic isoform switch from pyruvate kinase muscle (PKM) isoform 1 to 2 and from increased mitochondrial fission, due either to upregulation of expression of dynamin-related protein 1 (Drp1) or its binding partners, mitochondrial dynamics protein of 49 or 51 kDa (MiD49 or 51).

Aortic dilatation in complex congenital heart disease.

Authors:
Koichiro Niwa

Cardiovasc Diagn Ther 2018 Dec;8(6):725-738

Department of Cardiology, Cardiovascular Center, St Luke's International Hospital, Tokyo, Japan.

A bicuspid aortic valve and/or coarctation of the aorta (COA) are often associated with dilatation of the ascending aorta and para-coarctation. Congenital heart diseases (CHD), such as truncus arteriosus, transposition of the great arteries (TGA), tetralogy of Fallot (TOF), hypoplastic left heart syndrome (HLHS), single ventricle with pulmonary stenosis/atresia and the Fontan procedure, are also associated with aortic root dilatation, aneurysm and rarely, dissection, which can be fatal and require aortic valve and root surgery. A significant subset of adults with complex CHD exhibit progressive dilatation of the aortic root even after repair due to aortic medial degeneration. Read More

O Lairez

Rev Med Interne 2019 Feb 7. Epub 2019 Feb 7.

Fédération médico-chirurgicale de cardiologie, CHU Rangueil, 1, avenue Jean-Poulhès, TSA 50032, 31059 Toulouse cedex 9, France; Centre d'imagerie cardiaque, CHU de Toulouse, 31000 Toulouse, France; Faculté de médecine Toulouse - Purpan, université Paul-Sabatier, 31000 Toulouse, France. Electronic address:

Hypertrophic cardiomyopathies represent a heterogeneous group of pathophysiological mechanisms and etiologies (genetic or not), which lead to the development of left ventricular hypertrophy. Left ventricular hypertrophy, when not explained by a significant and prolonged increase in post-load (such as severe poorly controlled arterial hypertension or severe aortic stenosis) justifies etiological exploration. The etiology may range from physiological adaptation in the athlete to myocardial involvement, isolated or integrated as part of a global neuromuscular involvement; metabolic or mitochondrial disease to deposition disease.

The great choke, Ovation® aortic body graft stenosis.

Vascular 2019 Feb 10:1708538118820442. Epub 2019 Feb 10.

Total Vascular Care®, Brooklyn, NY, USA.

Introduction: Abdominal endovascular aneurysm repair is a minimally invasive alternative to major open surgery for the repair of abdominal aortic aneurysms that results in reduced recovery times and early survival rates.

Methods: The TriVascular Ovation® Abdominal Stent Graft System is a low-profile endovascular device with active fixation used for endovascular aneurysm repair. The stent graft is designed to reline the diseased vasculature, providing an endovascular blood conduit for isolating the aneurysm from the high-pressure flow of blood, thereby reducing the risk of rupture.

Transcatheter aortic valve replacement for pure aortic valve regurgitation: "on-label" versus "off-label" use of TAVR devices.

Clin Res Cardiol 2019 Feb 8. Epub 2019 Feb 8.

Department of Cardiology, University Heart Center Berlin and Charité University Medicine Berlin, Campus Benjamin-Franklin, Berlin, Germany.

Introduction: Transcatheter aortic valve replacement (TAVR) has become the mainstay of treatment for aortic stenosis in patients with high surgical risk. Pure aortic regurgitation (PAR) is considered a relative contraindication for TAVR; however, TAVR is increasingly performed in PAR patients with unfavorable risk profile. Herein, we aim to summarize available data on TAVR for PAR with special emphasis on "on-label" versus "off-label" TAVR devices. Read More

Hemodynamics of paradoxical severe aortic stenosis: insight from a pressure-volume loop analysis.

Clin Res Cardiol 2019 Feb 8. Epub 2019 Feb 8.

Cardiovascular Center, St. Josef Hospital Bochum, Ruhr-University Bochum, Gudrunstraße 56, 44791, Bochum, Germany.

Background: Controversy exists about the pathophysiology of different hemodynamic subgroups of AS. In particular, the mechanism of the paradoxical low-flow, low-gradient (PLFLG) AS with preserved ejection fraction (EF) is unclear.

Methods: A total of 41 patients with severe, symptomatic AS were divided into the following 4 subgroups based on the echocardiographically determined hemodynamics: (1) normal-flow, high-gradient (NFHG) AS; (2) low-flow, high-gradient AS; (3) paradoxical low-flow, low-gradient (PLFLG) AS with preserved EF and (4) low-flow, low-gradient (LFLG) AS with reduced EF.
