Isolated Ventricular Noncompaction Cardiomyopathy Presenting as Recurrent Syncope

Isolated ventricular noncompaction (IVNC) occurs because of interruption of trabecular morphogenesis in the myocardium leading to ventricular noncompaction. Patients present with heart failure or with systemic complications secondary to thromboembolism or arrhythmias. High index of suspicion is necessary for early diagnosis. We present a case of 48-year-old male with unexplained recurrent syncope who was eventually diagnosed with IVNC

Broken Heart Syndrome in a Patient on Maintenance Hemodialysis

Context:Broken heart syndrome or Takotsubo cardiomyopathy (TC) is a disorder characterized by transient left ventricular apical ballooning that almost invariably precedes emotional or physical stress. Although the patients with chronic kidney disease on hemodialysis have shown to exhibit sustained activity of sympathetic nervous system, the presentation of TC in these patients is a rare entity with few case reports in the literature. Case Report: A 75-year-old female with past medical history of end-stage renal disease presented with chest pressure and heaviness that started during her maintenance hemodialysis session. Electrocardiogram showed ST elevation and T wave inversion in V3-V6 leads. Emergent left heart catheterization was done that showed normal coronaries and akinesis of apical left ventricle wall consistent with TC. She was started on maximal medical management and underwent hemodialysis the next day without recurrence of the symptoms. Conclusion: TC may an underdiagnosed entity in patients on hemodialysis. However, it should be considered in the differential diagnosis in hemodialysis patients, particularly who presents with chest pain and/or symptoms

Preparation and properties of electrodeposited Ni-TiO2 composite coating

The mechanical properties of cutting tools, such as microhardness, corrosion resistance, and coating adhesiveness, directly affect the tool life and indirectly affect the component cost. In this paper, Ni-TiO2 composite coating was prepared through electrocodeposition in order to improve the mechanical properties of tungsten carbide cutting tools. The microhardness of the Ni-TiO2 composite layer was studied by varying the input current density (mA cm-2), pH value of the electrolyte, and particle concentration of TiO2 in electrolyte bath. The microstructure and phase structure of the composite layer were investigated using atomic force microscopy , scanning electronic microscopy and X-ray diffraction. The surface morphology of the Ni-TiO2 coated layer shows fine-grained structures and higher microhardness at lower currents. The maximum microhardness of the coated layer, 1483 HV, is found at a current of 15 mA cm-2 and Watts solution pH of 4.5. It is observed that with the increase of TiO2 content, the microhardness of the coating also increases

A Case of Anomalous Left Anterior Descending Artery Originating From the Right Sinus of Valsalva

The anomalous origin of coronary arteries has been extensively documented in the literature. Most of the anomalies are incidentally found either during coronary angiography or imaging studies and are usually benign; however, malignant outcomes have been reported in the literature. Here, we present the case of a 76-year-old male with non-ST segment elevation myocardial infarction who was found to have an asymptomatic anomalous origin left anterior descending artery from the right sinus of Valsalva
