BACKGROUND: Patients undergoing transcatheter aortic valve replacement can experience severe perioperative complications leading to hemodynamic instability and death. Venoarterial extracorporeal membrane oxygenation can be used to provide cardiorespiratory support during this time. METHODS: From 2012 to 2015, of 247 patients who underwent transcatheter aortic valve replacement, 6 (2.42%) required extracorporeal membrane oxygenation support. Their mean age was 82 ± 7...

REVIEW
Stefan Peters
In 19 patients (14 females, mean age 49.1 ± 11.3 years) with typical arrhythmogenic cardiomyopathy and provocable type I Brugada ECG pattern by ajmaline administration were analysed by novel electrocardiographic features as having "true" or "false" Brugada syndrome. Three patients turned out as having false Brugada syndrome, the diagnosis is pure arrhythmogenic cardiomyopathy. In 16 patients, however, true Brugada syndrome could be provoked. In these patients the diagnosis was arrhythmogenic cardiomyopathy associated by provocable Brugada syndrome...

Creutzfeldt-Jakob disease (CJD) is a rare neurodegenerative disorder characterized by rapidly progressing dementia, general neurologic deterioration, and death. When the leading symptoms are visual disturbances, it is termed as the Heidenhain variant of CJD (HvCJD). CJD was reported following prion-contaminated pericardium transplants but never after bovine bioprosthetic cardiac valve. In this case report, we describe HvCJD in a patient who had a bovine bioprosthetic cardiac valve implant. An 82-year-old-woman was referred to neuro-ophthalmology clinic for unexplained visual loss that started 1 month previously...

OBJECTIVES: In this study, we compare procedural results of our first Evolut R (Medtronic, Minneapolis, MN, USA) implantations with the last CoreValve implantations. Main endpoints include paravalvular regurgitation, major vascular complications, stroke, and pacemaker implantation. BACKGROUND: The evolution of transcatheter aortic valve replacement (TAVR) was possible due to various technical improvements, leading to better periprocedural and long-term outcome. The newly designed Evolut R valve has the potential to further improve TAVR's performance...

Paravalvular leak (PVL) is a serious complication after surgical valve replacement or after transcatheter aortic valve replacement. Approximately 1-5% of PVLs can lead to serious clinical consequences, including congestive heart failure and/or haemolytic anaemia. For years, surgical re-intervention has been considered the treatment of choice for symptomatic patients with PVLs. However, surgical re-intervention is associated with a high risk of morbidity and mortality. Transcatheter PVL (TPVL) closure is a less invasive alternative to surgical re-intervention...

New-onset systolic anterior motion of the anterior mitral valve leaflet in patients undergoing transcatheter aortic valve replacement is a rare pathophysiologic mechanism leading to postprocedural development of mitral regurgitation and, eventually, left ventricular outflow obstruction. We report the first human case of successful MitraClip implantation to treat new-onset systolic anterior motion of the mitral valve after transcatheter aortic valve replacement causing severe obstruction to left ventricular outflow that was unresponsive to standard medical therapy...

OBJECTIVES: The purpose of this study was to evaluate the incidence, predictors, and clinical outcomes of permanent pacemaker (PPM) implantation following transcatheter aortic valve replacement (TAVR). BACKGROUND: Conduction abnormalities leading to PPM implantation are common complications following TAVR. Whether PPM placement can be predicted or is associated with adverse outcomes is unclear. METHODS: A retrospective cohort study of patients undergoing TAVR in the United States at 229 sites between November 2011 and September 2014 was performed using the Society of Thoracic Surgeons/American College of Cardiology TVT Registry and the Centers for Medicare and Medicaid Services database...

Combinatorial test design is a plan of test that aims to reduce the amount of test cases systematically by choosing a subset of the test cases based on the combination of input variables. The subset covers all possible combinations of a given strength and hence tries to match the effectiveness of the exhaustive set. This mechanism of reduction has been used successfully in software testing research with t-way testing (where t indicates the interaction strength of combinations). Potentially, other systems may exhibit many similarities with this approach...

Background. Heart disease is the leading cause of nonobstetric mortality in pregnant women. Because of high risk, medical management represents the first line of treatment. However, when medical treatment fails, cardiac surgery becomes necessary. Case Presentation. A 27-year-old female who underwent successfully cardiac surgery three times within 3 years. At the first time, she had an aortic valve replacement at 25 weeks of gestation after an infectious endocarditis complicated with an ischemic stroke. At 39 weeks of gestation, she had delivered, vaginally, a healthy baby boy weighing 2800 g...

INTRODUCTION: Percutaneous aortic valve replacement (transcatheter aortic valve implantation (TAVI)) notably increases the likelihood of the appearance of a complete left bundle branch block (LBBB) by direct lesion of the LBB of His. This block can lead to high-grade atrioventricular conduction disturbances responsible for a poorer prognosis. The management of this complication remains controversial. METHOD AND ANALYSIS: The screening of LBBB after TAVI persisting for more than 24 hours will be conducted by surface ECG...

Management of dialysis patients with valvular heart disease waitlisted for kidney transplantation is challenging. Development of severe aortic valve stenosis can lead to the exclusion from the transplant program or even death while on the waiting list. In dialysis patients, surgical aortic valve replacement is associated with a high perioperative risk with increased morbidity and mortality. In contrast, transcatheter aortic valve implantation emerges as a viable option for dialysis patients. Herein, we present the long-term follow-up of successful kidney transplantation after TAVI in a diabetic patient receiving long-term hemodialysis...

Risk factors of heart valve disease are well defined and prolonged exposure throughout life leads to degeneration and dysfunction in up to 33% of the population. While aortic valve replacement remains the most common need for cardiovascular surgery particularly in those aged over 65, the underlying mechanisms of progressive deterioration are unknown. In other cardiovascular systems, a decline in endothelial cell integrity and function play a major role in promoting pathological changes, and while similar mechanisms have been speculated in the valves, studies to support this are lacking...

In typical takotsubo cardiomyopathy (TC) apical transient left ventricular dysfunction with concomitant ECG changes mimicking acute anterior myocardial infarction can be observed. Reverse TC (RTC) characterized by contractile disturbances in all basal and often simultaneous mid-ventricular segments is definitely less frequent. ECG pattern of RTC is less known. The authors present ECG findings in 5 cases of RTC in course of intracranial hemorrhage (ICH); 3 patients were diagnosed with subarachnoid hemorrhage (SAH) and the other two with intracerebral hemorrhage or subdural posttraumatic hematoma...

BACKGROUND AND AIMS: Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common form of paroxysmal supraventricular tachycardia (SVT) whose diagnosis can be strongly suspected based on the surface eletrocardiogram alone. The purpose of this study is to determine the diagnostic accuracy of several electrocardiographic (ECG) criteria for the prediction of AVNRT. METHODS: Between November 2010 and January 2014, a total of 256 patients who underwent electrophysiological testing (EP) with regular, paroxysmal and narrow QRS complex tachycardia were prospectively enrolled...

Prediction of left main coronary artery (LMCA) or equivalent disease is important with regard to selecting the appropriate treatment strategy. The classical electrocardiographic pattern of LMCA disease includes ST elevation (STE) in lead aVR in the presence of extensive ST depression (most prominent in leads I, II, and V4-6) with the STE in aVR≥V1. Patients with these findings may potentially require early coronary angiography and coronary bypass surgery; therefore selected patients with these findings on exercise testing might benefit from more urgent or expedited angiography...
