BACKGROUND: In this study, we sought to analyze the incidence and relevance of von Willebrand factor (VWF) abnormalities in patients undergoing transcatheter aortic valve implantation (TAVI), especially on perioperative bleeding. Furthermore, we hypothesized that, similar to aortic valve surgery, TAVI results in a restoration of VWF abnormalities. METHODS AND RESULTS: We performed a prospective analysis of periinterventional VWF parameters in 74 patients (80±7years, female in 37...

RATIONALE: Drug-induced valvular heart disease (DI-VHD) remains an under-recognized entity. PATIENT CONCERNS: This report describes a heart valve replacement which was complicated by intractable systemic pulmonary arterial hypertension in a 61-year-old female with severe restrictive mitral and aortic disease. The diagnosis of valvular disease was preceded by a history of unexplained respiratory distress. The patient had been exposed to benfluorex for 6.5 years. DIAGNOSES: The diagnostic procedure documented specific drug-induced valvular fibrosis...

A woman underwent ascending aortic aneurysm repair, aortic root and valve replacement, and coronary artery bypass grafting. Her postoperative course was complicated by stroke and status epilepticus. With supportive care and antiepileptics, her neurologic status improved. Intravenous heparin and aspirin were initiated. On postoperative day 13, she developed a large retroperitoneal hematoma with femoral neuropathy. Because her hematoma was not amenable to percutaneous drainage or surgical evacuation, and considering her comorbidities, a conservative approach was elected...

Remodelling in the atria could appear as a result of hypertension, diabetes or ischaemic heart disease. Galectin-3 (Gal-3) is a mediator of profibrotic pathways and a potential biomarker of cardiac remodelling. We prospectively recruited consecutive patients undergoing elective cardiac surgery. Preoperative Gal-3 levels were determined from serum samples, and the presence of fibrosis was assessed from atrial appendage tissue samples obtained during cardiac surgery. We included 100 patients with aortic valve or ischaemic heart diseases and 15 controls with permanent AF...

The venous anomaly of a persistent left superior vena cava (PLSVC) affects 0.3%-0.5% of the general population. PLSVC with absent right superior vena cava, also termed as "isolated PLSVC," is an extremely rare venous anomaly. Almost half of the patients with isolated PLSVC have cardiac anomalies in the form of atrial septal defect, endocardial cushion defects, or tetralogy of Fallot. Isolated PLSVC is usually innocuous. Its discovery, however, has important clinical implications. It can pose clinical difficulties with central venous access, cardiothoracic surgeries, and pacemaker implantation...

Background There are limited data regarding the risks of cardiac surgery early after coronary angiography in patients scheduled for isolated aortic and/or mitral valve replacement. Our aim was to evaluate the risk of early surgery after coronary angiography in these patients. Methods We retrospectively analyzed data of 1044 patients who underwent isolated aortic and/or mitral valve replacement from 2006 to 2014. Baseline, operative, and postoperative variables were collected. The patients were divided into 3 groups based on the interval between coronary angiography and surgery: ≤3 days ( n = 216), 4-7 days ( n = 109), and ≥8 days ( n = 719)...

INTRODUCTION: Rapid deployment valves (RDV) represent a newly introduced approach to aortic valve replacement which facilitates surgical implantation and minimally invasive techniques, shortens surgical times and shows excellent haemodynamic performance. However, evidence on their safety, efficacy and potential complications is mostly fitted with small-volume and retrospective studies. Moreover, no current guidelines exist. To improve our knowledge on this technology, The Rapid Deployment Aortic Replacement (RADAR) Registry will be established across Spain with the aim of assessing RDV outcomes in the real-world setting...

The current trend to treat hypotension in critically ill patients is to place a greater emphasis on inotropic support and less on fluid resuscitation in order to limit the potential harm from fluid overload. This combination may trigger left ventricular outflow tract obstruction (LVOTO) in susceptible patients. Although LVOTO is classically described in patients with hypertrophic cardiomyopathy it has been reported in other conditions including septic shock, apical ballooning syndrome, myocardial infarction, respiratory failure, and post valvular surgery...

BACKGROUND: The management of Dengue virus infection can be challenging. Varied presentations and numerous complications intrinsic to dengue by itself increase the complexity of treatment and potential mortality. When burdened with the presence of additional comorbidities and the need to continue compulsory medications, clear stepwise definitive guidance is lacking and patients tend to have more complex complications and outcomes calling to question the clinical decisions that may have been taken...
