Emergent pulmonary thromboembolectomy and atrial septal aneurysmectomy for intracardiac impending paradoxical embolism: An en bloc approach to prevent clot embolism and facilitate repair.

Although a patent foramen ovale (PFO) is relatively common, confirmed reports of thrombus entrapped within a PFO are uncommon. Management of impending paradoxical embolism (IPE), also called a thrombus in transit, lacks consensus but includes systemic anticoagulation (e.g.

Potential alteration of tumor microenvironments by β-mercaptoethanol.

The therapeutic effectiveness of immune checkpoint inhibitors in cancer patients is quite profound. However, it is generally accepted that further progress is curtailed by accompanying adverse events and by low cure rates linked to the tumor microenvironment. The multitudes of immune processes altered by low-molecular-weight thiols published over the past decades suggest they have potential to alter tumor microenvironment processes which could result in an increase in immune checkpoint inhibitor survival rates.

Unusual Cause of Heart Failure in a Patient with Marfan Syndrome: A Late Complication of Bioprosthetic Valved Graft Replacement.

A high-velocity gradient across the left ventricular outflow tract is most often caused by aortic valve stenosis. We describe the unusual case of a high-velocity gradient caused by a kinked ascending aortic graft in a 69-year-old man who had Marfan syndrome. The patient had a history of ascending aortic aneurysm and had previously undergone replacement of the aortic root and ascending aorta with use of a bioprosthetic valved graft.

Echocardiography in centenarians: characteristics, utility and follow-up.

Background: Echocardiography has been shown to be a valuable resource in the diagnosis of many cardiac conditions, and can be used in all age groups, from the fetus to the oldest old. In the context of an increasingly aging population, the impact and utility of echocardiography in centenarians is largely unknown. This study is to determine whether echocardiography in centenarians aids in making clinical patient management decisions.

Cardiac melanoma: Retrospective review of a rare disease at the Mayo clinic (1988-2015).

Background: Melanoma metastasizing to the heart (cardiac melanoma) is a rare entity that has been described only in autopsy studies or isolated pre-mortem case reports. We aim to better characterize cardiac melanoma, and describe its presenting features, imaging findings, and disease course with a case series collected over nearly 30years.

Methods: We performed a retrospective review of all patients diagnosed with cardiac melanoma at the Mayo Clinic from 1988 to 2015.

Visual Estimation of the Severity of Aortic Stenosis and the Calcium Burden by 2-Dimensional Echocardiography: Is It Reliable?

Objectives: Guidelines have recommended aortic valve surgery in asymptomatic patients with severe aortic stenosis and a large aortic valve calcium burden. The purpose of this study was to determine whether visual assessment of aortic valve calcium and stenosis severity are reliable based on 2-dimensional echocardiography alone.

Methods: We prospectively enrolled 68 patients with aortic stenosis and compared them with 30 control participants without aortic stenosis.

A review: alteration of in vitro reproduction processes by thiols -emphasis on 2-mercaptoethanol.

Descriptions of organosulfurs altering biologically relevant cellular functions began some 40 years ago when murine in vitro cell mediated and humoral immune responses were shown to be dramatically enhanced by any of four xenobiotic, sulfhydryl compounds-2-mercaptoethanol (2ME), dithiothreitol (DTT), glutathione, and L-cysteine; the most effective were 2ME and DTT. These findings triggered a plethora of reports defining 2ME benefits for a multitude of immunological processes. This in turn led to investigations on 2ME alterations of (a) immune functions in other species, (b) activities of other cell-types, and (c) in vivo diseases.

Alteration of radiation-sensitive processes associated with cancer and longevity by dietary 2-mercaptoethanol.

Background: Previous results demonstrated dietary 2-mercaptoethanol (2-ME) delayed appearance of cancer in certain murine strains. In addition, it had a benefit not found with other organosulfurs, in that it completely prevented spontaneous development of cancer in BXSB-Yaa + over an entire lifespan.

Aims: These benefits raise the question: What, if any, alteration of radiation-induced tumorigenesis would 2-ME impart that may differ from that of other sulfur antioxidants? This is relevant based on the extensive use of radiation in diagnoses and therapy and 2-ME's superior in vitro and in situ immune enhancement properties.

3D echocardiography in cardiac surgery.

Herein, we present a patient who underwent successful repair of failed mitral valve repair in whom intraoperative 3D transesophageal echocardiography provided accurate assessment of the mechanism of mitral regurgitation. In addition, we review the potential advantages and limitations of 3D echocardiography and its role in cardiac surgery.

Review: 2-mercaptoethanol alteration of in vitro immune functions of species other than murine.

Descriptions that organosulfurs could alter biologically relevant cellular functions began some 40years ago when cell mediated and humoral murine in vitro immune responses were reported to be dramatically enhanced by any of four xenobiotic, sulfhydryl compounds-2-mercaptoethanol (2-ME), dithiothreitol, glutathione, and l-cysteine; the most effective of the four was 2-ME. These findings triggered a plethora of reports defining 2-ME benefits for a multitude of immunological processes, primarily with murine models. This led to investigations on 2-ME alterations of (a) immune functions in other species, (b) activities of other cell-types, and (c) in situ diseases.

Papillary fibroelastoma of the pulmonary valve--a systematic review.

The pulmonary valve is the least affected site for valvular papillary fibroelastoma. With increasing use of routine echocardiography and other modalities of imaging, pulmonary valve papillary fibroelastomas (PVPFE) are being recognized more frequently. PVPFE is more often an incidental diagnosis and symptomatic patients usually present with shortness of breath.

Dietary supplemented 2-mercaptoethanol prevents spontaneous and delays virally-induced murine mammary tumorigenesis.

There seems to be little doubt that organosulfur compounds have enormous benefits for biological processes, especially those of diseases like cancer. The preliminary results herein define a cancer model in which benefits/mechanisms of multitudes of xenobiotic and nature's organosulfurs could easily be compared. Mice from three strains with a high incidence for naturally occurring tumors were treated daily with 2-mercaptoethanol (2-Me) starting at weaning.

Valvular heart disease in patients with osteogenesis imperfecta.

Osteogenesis imperfecta (OI) or "brittle bone disease" is a rare connective tissue hereditary disorder. The most common clinical presentation of OI is bone fractures. OI also involves extraskeletal structures; however, cardiovascular manifestations are rare.

Anticancer activity and chemoprevention of xenobiotic organosulfurs in preclinical model systems.

There seems to be little doubt that xenobiotic and plant derived organosulfur compounds have enormous benefits for in vitro cellular functions and for a multitude of diseases, including cancer. Since there are numerous reviews on anticancer activities of plant organosulfurs, the focus herein will be on alterations associated with xenobiotic organosulfurs. Benefits of 2-mercaptoethanol (2-Me), N-Acetyl-cysteine, cysteamine, thioproline, piroxicam, disulfiram, amifostine, sulindac, celecoxib, oltipraz and their derivates on transplanted homologous tumors and on autochthonous cancers with a viral-, radiation-, chemical carcinogen-, and undefined-etiology are assessed.
