Isolated infectious endocarditis of the pulmonary valve is a rare condition and represents 1,5-2% of all cases of infectious endocarditis. We present a case of a 37year-old woman without any relevant medical history. The woman was hospitalized with hallmarks of severe sepsis and bilateral pneumonia; she died several hours after admission with progressive multiorgan failure and disseminated intravascular coagulopathy. Microbiologic examination approved Staphylococcus aureus as the etiological agent. The autopsy showed isolated endocarditis of the pulmonary valve, without any known predisposing factor...

A bronchopleural fistula (BPF) is a communication between the pleural space and the bronchial tree. BPFs are challenging to diagnose and are associated with a high morbidity and mortality. Sequential balloon occlusion is commonly used for localization of a BPF. We describe our experience with 4 cases of successful localization of the BPF by instillation of methylene blue into the pleural space through a pigtail catheter, with simultaneous bronchoscopic visualization of dye in the tracheobronchial tree. Two patients were treated with endobronchial valves and 3 had a surgical thoracic muscle flap placed...

We report the unexpected transesophageal echocardiography (TEE) finding of a left atrial (LA) thrombus near the end of cardiopulmonary bypass and after deployment of an AtriClip (Atricure, Inc, Westchester, OH) in an 84-year-old man with atrial fibrillation and aortic stenosis undergoing aortic valve replacement and LA appendage ligation. TEE examination before cardiopulmonary bypass and deployment of the AtriClip had not shown a thrombus in the LA appendage. The heart was rearrested and thrombus was successfully removed through a left atriotomy...

AIM: Anderson-Fabry disease (AFD) is a hereditary disorder caused by a deficiency in the lysosomal enzyme α-galactosidase A which causes dysfunctions in multiple organ systems. Cardiac manifestation includes left ventricular hypertrophy, thickening of the valves, conduction disturbances and in the late phase, extensive areas of myocardial fibrosis with increased risk of sudden cardiac death. Case example: A case of AFD with exclusive cardiac involvement is described. During follow-up, due to the high risk of life-threatening arrhythmic events, implantation of an implantable cardioverter defibrillator is performed...

Transcatheter aortic valve replacement (TAVR) has become the standard of care for the treatment of severe aortic stenosis in individuals who are at prohibitive surgical risk and presents a viable alternative to surgery in selected patients who are at high operative risk. To date, outcomes from the PARTNER (Placement of AoRtic TraNscathetER Valve) and Medtronic CoreValve® US Pivotal trials continue to show the benefits of TAVR in these high-risk subgroups out to 5 and 3 years, respectively (as reported by Mack et al...

Subacute bacterial endocarditis can have many different presentations; in rare instances, it can present as leukocytoclastic vasculitis owing to the effect of circulating immune complexes and micro-emboli on the vascular endothelium. A high index of suspicion needs to be maintained to differentiate between infectious vs noninfectious autoimmune vasculitides, keeping in mind that missing a diagnosis can have fatal results. In this case report, we introduce a young female patient who initially presented with a picture of idiopathic autoimmune cutaneous vasculitis delaying the diagnosis of an underlying infective endocarditis with aortic valve involvement...

Many tissues exhibit subatmospheric interstitial pressures under normal physiologic conditions. The mechanisms by which the lymphatic system extracts fluid from these tissues against the overall pressure gradient are unknown. We address this important physiologic issue by combining experimental measurements of contractile function and pressure generation with a previously validated mathematical model. We provide definitive evidence for the existence of 'suction pressure' in collecting lymphatic vessels, which manifests as a transient drop in pressure downstream of the inlet valve following contraction...

Management of aortic valve disease and, in particular, aortic valve stenosis has evolved through the course of time from medical management and balloon valvuloplasty to the presumed gold-standard surgical intervention. However, with the advent of surgical innovation, intra- and postoperative patients monitoring, understanding of hemodynamic dysfunction, and choices of prosthesis, conventional surgical aortic valve replacements are currently being challenged in particular in moderate- and high-risk patients...

Enlarging or "cracking" a surgical stented bioprosthetic valve during valve-in-valve transcatheter aortic valve implantation (TAVI) increases orifice area, reducing transvalvular energy losses. We demonstrate that TAVI with valve cracking can be used to treat paravalvular leak (PVL) while providing optimal aortic valve physiology. A 61-year-old woman with a history of aortic valve replacement with a stented bioprosthesis presented with heart failure. Transthoracic echocardiography revealed severe prosthetic aortic valve stenosis with PVL and severe regurgitation...

We report a case of an adolescent young man who presented with embolism of both lower legs. The patient had undergone mitral valve repair with a Kalangos biodegradable ring (Bioring SA, Lonay, Switzerland) 9 months earlier. Bilateral embolectomy was performed. Histopathologic examination revealed minute fragments of synthetic material within the embolus, which otherwise consisted of recent thrombus.

PURPOSE: Suprasternal transcatheter aortic valve replacement offers patients, with unsuitable femoral artery anatomy, an alternative to transapical, direct aortic, and subclavian approaches. DESCRIPTION: The Transit System (Aegis Surgical, Galway, Ireland) enables transcatheter aortic valve replacement directly into the ascending aorta or innominate artery through a small, suprasternal incision. The valve introducer sheath is inserted through a standard pursestring suture, which facilitates secure arterial closure...

REVIEW

Compared with traditional exercise tests, cardiopulmonary exercise testing (CPET) provides a thorough assessment of exercise integrative physiology involving the pulmonary, cardiovascular, muscular, and cellular oxidative systems. Due to the prognostic ability of key variables, CPET applications in cardiology have grown impressively to include all forms of exercise intolerance, with a predominant focus on heart failure with reduced or with preserved ejection fraction. As impaired cardiac output and peripheral oxygen diffusion are the main determinants of the abnormal functional response in cardiac patients, invasive CPET has gained new popularity, especially for diagnosing early heart failure with preserved ejection fraction and exercise-induced pulmonary hypertension...

This Research Paper addresses the hypothesis that using teatcups with automatic valves, without cutting off the vacuum prior to cluster removal, could increases the risk of mastitis and affect other milking variables on goats. A first trial used 46 intramammary infection (IMI)-free goats that had been milked with normal teatcups (without automatic valves) during a pre-experimental period of 8 ± 2 d postpartum. These animals were divided into two groups (n = 23), randomly assigning each group to teatcups with automatic valves (teatcups A) or without automatic valves (teatcups B) for a 20-week experimental period...
