Atrioventricular (AV)-nodal-reentrant-tachycardia is a rare association in a patient with persistent left-sided superior vena cava and dilated coronary sinus. There are a few inherent difficulties in ablation in this condition, viz., difficulty in localization of good site for ablation and difficulty in stabilization of the ablation catheter at the designated site, making it difficult to produce transmural lesions and increasing risk of producing AV block. We hereby present a case highlighting the difficulties and possible solutions for them.

Observational Study
Impact of oxygen therapy algorithm on oxygen usage in the emergency department.
Although oxygen is one of the oldest drugs available, it is still one of the most inappropriately administered drugs leading to over utilization of this very expensive resource. ⋯ The implementation of an oxygen therapy algorithm significantly reduces inappropriate oxygen use and decreases treatment cost to the patient with no additional mortality risk.

This retrospective study analyzed the level of concordance between clinical and autopsy diagnosis of coarctation of aorta over 10 years. Utilizing the Goldmann classification, the concordance rate was found to be 16%. Major discrepancies (Class I and II) were found in 56% cases and minor discrepancies (Class III and IV) in 28% cases.

Pulmonary microvascular tumor embolism (PMTE), pulmonary tumor thrombotic microangiopathy (PTTM), and lymphangitis carcinomatosis (LC) have an intricate pathophysiology and usually occur with cancers of breast, stomach, and lung. Microvascular pulmonary metastases attributable to cervical cancer are a rarity. Clinical presentation and autopsy findings of patients with microvascular pulmonary metastases in cervical cancers were studied with a review of literature. ⋯ Autopsy examination performed on each patient depicted varying combination of PMTE, PTTM, and LC, all with squamous histology. This case series highlights the rare association of carcinoma cervix with the aforementioned microvascular phenomena. Besides, it underscores the sequential mechanism of occurrence of microvascular pulmonary metastasis and the associated guarded prognosis.
