Heart Block in Dextrocardia and Situs Inversus:

Abstract

The authors report a case of a 39-year-old woman with dextrocardia and situs inversus who presented with episodes of complete heart block, managed successfully with a permanent dual chamber endocardial pacemaker.

Cardiac Resynchronization Therapy Upgrade in a Patient with Dextrocardia and Situs Inversus Totalis, Facilitated by Coronary Sinus Cannulation with Electrophysiology Catheters from Both Femoral and Axillary Venous Approaches

“…There are case reports published on the association of both congenital heart block and acquired degeneration of the conduction system with DX-SIT. [7][8][9] Regardless, the exact mechanism of complete heart block in this case is still not clear.…”

“…7 There are case reports of early to mid-adulthood presentations of complete heart block in association with dextrocardia. 8,9 This phenomenon could possibly be due to idiopathic degeneration of the conduction system or delayed requirement for cardiac pacing associated with congenital heart block.…”

Implantation of a completely right sided subcutaneous cardioverter-defibrillator in a patient with situs inversus dextrocardia

“…These factors would require additional testing, use of contrast, and could potentially result in longer procedure times. Also, transvenous leads are exposed to added stress due to the angle generated by the abnormal course of the superior vena cava relative to the reversed position of the right atrium and ventricle in patients with dextrocardia [4].…”

A patient with dextrocardia and chagas disease: case report and literature review

“…Although knowledge of Chagas disease is always increasing, little is known about patients living with it and congenital anatomic abnormalities such as dextrocardia, situs inversus totalis, or others. This could be explained because it is a relatively rare condition; for example, its prevalence in the United States is estimated at about 2 patients per 10 000-20 000 inhabitants (21).…”

“…Changes in electrocardiography and imaging scans are helpful diagnostic aids, but clinical approach, clinical judgment and suspicion are also needed (22,23). Inverted P, QRS, and T waves in D1, as well as a progressive increase in R waves in precordial leads, are common electrocardiographic findings (21).…”
