Importance of Arrhythmic Origin in the Diagnosis of Isolated Cardiac Sarcoidosis: A Case Report.

Sarcoidosis has a heterogeneous clinical presentation and remains difficult to diagnose, especially in isolated cardiac sarcoidosis (CS). We report a case of life-threatening arrhythmia that led to the diagnosis of isolated CS. A 63-year-old man presented with sustained ventricular tachycardia that was thought to originate from the anterolateral free wall of the right ventricle.

Isolated extreme right ventricular hypertrophy: A case report.

Hypertrophic cardiomyopathy (HCM) can involve the right ventricle (RV), although RV hypertrophy usually exists with left ventricular (LV) hypertrophy and the severity of hypertrophy is milder in the RV than in the LV. We report a case of isolated extreme RV hypertrophy with a maximum RV wall thickness of 40 mm. A 72-year-old man presented with an abnormal electrocardiogram and isolated hypertrophy of the RV apex was found on echocardiography.

Iatrogenic Thoracic Duct Injury via the Right Internal Jugular Vein: A Case Report.

Thoracic duct injury is a rare mechanical complication during the insertion of a central venous cannula via the left internal jugular vein. We report a case of thoracic duct injury during the insertion of a temporary pacing lead via the right internal jugular vein. A 92-year-old woman presented with third-degree atrioventricular block.

Jugular Venous Pressure Response to Inspiration for Risk Assessment of Heart Failure.

Simplifying jugular venous pressure (JVP), visibility of the right internal jugular vein above the right clavicle in the sitting position, has been proposed in the management of heart failure (HF) because of its convenience. However, this method may be undervalued for the detection of mildly to moderately increased JVP. Increased JVP on inspiration, known as Kussmaul sign, may be a useful physical finding in this condition.
