An 89-year-old woman appeared to have acute coronary syndrome at the left main trunk (LMT) complicated with severe aortic stenosis, moderate-severe mitral regurgitation, depressed left ventricular (LV) function, and multivessel disease. Because of sustained hypotension even under intra-aortic balloon pumping support during emergency coronary angiograhy, we performed primary percutaneous coronary intervention solely for the LMT lesion using a bare metal stent, leading to recovery from the shock state. On the second hospital day, based on our heart-team consensus, we performed aortic valve replacement and coronary artery bypass grafting surgery, and added edge-to-edge repair (Alfieri stitch) of the mitral valve, resulting in complete revascularization and dramatically improved LV function...

BACKGROUND: In the evolving field of transcatheter aortic valve replacements a new generation of valves have been introduced to clinical practice. With the complexity of the TAVR procedure and the unique aspects of each TAVR device, there is a perceived risk that changing or adding a new valve in a department could lead to a worse outcome for patients, especially during the learning phase. The objective was to study the safety aspect of introducing a second generation repositionable transcatheter valve (Boston Scientific Lotus valve besides Edwards Sapien valve) in a department...

AIMS: We analysed the number of procedures, indications, and in-hospital mortality rates of all patients undergoing isolated surgical aortic valve replacement (sAVR) or transvascular (TV-) and transapical (TA-) transcatheter aortic valve implantation (TAVI) from 2012 to 2015 in Germany. METHODS AND RESULTS: More than 31,000 aortic valve procedures were performed in 2015 in Germany, representing a total increase of 4.5% over 2014. TV-TAVI accounts for 13,108 of these procedures, with an increase of 21%, whereas the numbers of isolated sAVR and TA-TAVI decreased slightly...

Calcific aortic valve disease (CAVD) is the most prevalent valvular heart disease in the Western population, claiming 17000 deaths per year in the United States and affecting 25% of people older than 65 years of age. Contrary to traditional belief, CAVD is not a passive, degenerative disease but rather a dynamic disease, where initial cellular changes in the valve leaflets progress into fibrotic lesions that induce valve thickening and calcification. Advanced thickening and calcification impair valve function and lead to aortic stenosis (AS)...

BACKGROUND: Campylobacter spp. are a common cause of mostly self-limiting enterocolitis. Although rare, pericarditis and myopericarditis have been increasingly documented as complications following campylobacteriosis. Such cases have occurred predominantly in younger males, and involved a single causative species, namely Campylobacter jejuni. We report the first case of myopericarditis following Campylobacter coli enterocolitis, with illness occurring in an immunocompetent middle-aged female...

Coronary artery spasm is a known cause of acute coronary syndrome. However, left main coronary spasm is an extremely rare entity and can present in different ways depending on the duration and severity of the spasm. We present a 44-year-old female patient who presented with transient ST elevation in the lead aVR and ST depression in the lateral and inferior leads. Coronary angiography showed mid left main and ostial right coronary artery spasm that significantly improved after intracoronary nitroglycerine administration...

Aortic valve replacement (AVR) remains the cornerstone of treatment for symptomatic critical aortic stenosis (AS). It is a Class I indication that symptomatic patients with critical AS undergo either surgical or transcatheter aortic valve replacement (TAVR). We present a patient with critical AS and new angina that was managed successfully with percutaneous coronary intervention (PCI) of the Right coronary artery. Physicians should consider that not all patients with critical AS and angina necessarily require AVR...

AIMS: Clinical presentation of takotsubo syndrome (TTS) mimics acute coronary syndrome (ACS) and does not allow differentiation. We aimed to develop a clinical score to estimate the probability of TTS and to distinguish TTS from ACS in the acute stage. METHODS AND RESULTS: Patients with TTS were recruited from the International Takotsubo Registry ( www.takotsubo-registry.com) and ACS patients from the leading hospital in Zurich. A multiple logistic regression for the presence of TTS was performed in a derivation cohort (TTS, n = 218; ACS, n = 436)...

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...

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...
