“…84,85 Asystole/Atrioventricular Block Syncope and/or asystolic cardiac arrest due to high degree AV block or sinus arrest have been described in patients with TTS. [86][87][88][89] In patients with persistent AV block, a permanent pacemaker is implanted. 90 Importantly, any bradyarrhythmia, including complete AV block, may facilitate or trigger the occurrence of TdP via the mechanism of long-short sequence.…”

Takotsubo syndrome (TTS), triggered by intense emotional or physical stress, occurring most commonly in post-menopausal women, presents as an ST-elevation myocardial infarction (MI). Cardiovascular complications occur in almost half the patients with TTS, and the inpatient mortality is comparable to MI (4–5%) owing to cardiogenic shock, myocardial rupture, or life-threatening arrhythmias. Thus, its prognosis is not as benign as previously thought, as it may cause mechanical complications (cardiac rupture) and potentially lethal arrhythmias and sudden cardiac death (SCD). Similar to MI, some patients may perish before reaching the hospital due to out-of-hospital cardiac arrest; this may lead to underestimation of the actual SCD risk. Furthermore, after discharge, some patients may develop late SCD and/or TTS recurrence that may result in SCD. There are risk factors for SCD in TTS patients, such as severe/persistent QT-interval prolongation inciting torsade-de-pointes, other ECG abnormalities (diffuse giant negative T-waves, widened QRS-complex), bradyarrhythmias, comorbidities, concurrent obstructive coronary artery disease or vasospasm, male gender, older age, severe left ventricular dysfunction, and use of sympathomimetic drugs. All these issues are herein reviewed, case reports/series and data from large cohort studies and meta-analyses are analyzed, risk factors are tabulated, and proarrhythmic effects and management strategies are discussed and pictorially illustrated.

“…Blue nevus has been reported in the lymph nodes, parotid, and prostate glands 4 . In the oral cavity, blue nevus accounts for one-third of all oral mucosal melanocytic nevi, with the palate being the most common location 1,3 . This case report describes the clinical and histopathologic features of a common blue nevus located within the minor salivary gland tissue of the hard palate.…”

“…Microscopically, the blue nevus is composed of a benign proliferation of bipolar dendritic melanocytes in the deeper layers of the connective tissue 2 . The distinctive blue hue is attributed to the deep location of the melanocytes and the Tyndall effect, 1–3 whereby the tissue overlying the blue nevus absorbs light with longer wavelengths and allows the shorter wavelengths (ie, blue light) to be reflected to the surface 1 . Blue nevus has been reported in the lymph nodes, parotid, and prostate glands 4 .…”

Blue nevus is a benign melanocytic tumor that commonly occurs on the skin. It appears as a solitary, well-demarcated, dark blue nodule or smooth-surfaced macule. Blue nevus has been reported in the lymph nodes, parotid, and prostate glands. In the oral cavity, blue nevus accounts for one-third of all oral mucosal melanocytic nevi, with the palate being the most common location. Microscopically, the blue nevus is composed of a benign proliferation of bipolar dendritic melanocytes in the deeper layers of the connective tissue. The distinctive blue hue is attributed to the deep location of the melanocytes and the Tyndall effect. To our knowledge, this is the first article to document blue nevus involving minor salivary glands. One month following the excisional biopsy and thereafter, no evidence of recurrence was noted. The diagnosis was established only after histopathological examination of the biopsy specimen. Microscopic examination of oral pigmented lesions is necessary for a conclusive diagnosis and to rule out neoplasms such as melanoma that can clinically mimic blue nevus.

“…In VS, there is a lack of impulse formation in the cardiac conduction system which in turn causes the heart to stop beating at all. 6,7 During such episodes, lack of awareness of VS as a potential etiology may lead to delays in definitive care. 3 Here, we present a case of a patient who had numerous syncopal episodes and subsequent cardiac arrest as a result of underlying VS.…”
