Aksu T, Guler TE, Golcuk E, Erden I, Ozcan KS - Int Med Case Rep J (2015)

Bottom Line: Radiofrequency catheter ablation of the slow pathway is considered to be the treatment of choice for patients with atrioventricular nodal reentrant tachycardia.We report a 34-year-old female with mirror image dextrocardia due to unilateral pulmonary agenesis who underwent successful slow pathway ablation for typical atrioventricular nodal reentrant tachycardia.Using contrast injection, cardiac anatomy was identified in a short time and successfully ablated.

ABSTRACT
Radiofrequency catheter ablation of the slow pathway is considered to be the treatment of choice for patients with atrioventricular nodal reentrant tachycardia. We report a 34-year-old female with mirror image dextrocardia due to unilateral pulmonary agenesis who underwent successful slow pathway ablation for typical atrioventricular nodal reentrant tachycardia. Using contrast injection, cardiac anatomy was identified in a short time and successfully ablated.

f2-imcrj-8-041: Twelve-lead electrocardiogram showing supraventricular tachycardia with a regular, narrow QRS tachycardia at a rate of 170 bpm, during which the P wave was indiscernible, in a patient with dextroposition of the heart.

Mentions: A 35-year-old woman was admitted to our cardiology clinic with complaints of palpitation. She had a 7-year history of paroxysmal palpitations. The tachycardia, at a rate of 170–200 bpm, was associated with dyspnea and chest tightness and lasted for up to 60 minutes at a time. Her physical examination revealed no breathing sound on the right and a normal breathing sound on the left hemithorax, while the heart’s sound was heard from the right hemithorax. The chest radiogram incidentally showed a rudimentary, opacified right hemithorax with mediastinal shift and herniation of the contralateral lung. Except for dextroposition of the heart, two-dimensional echocardiogram showed no underlying heart disease. A 12-lead resting electrocardiogram (ECG) showed sinus rhythm at a rate of 64 bpm, a positive QRS complex in aVR, a positive P wave in aVR and a biphasic P wave in aVL, and a prominent R wave in V1 with undetermined horizontal axis (Figure 1). The clinical tachycardia was a regular, narrow QRS tachycardia at a rate of 170 bpm, during which the P wave was indiscernible (Figure 2). Computed tomography showed a complete absence of the right lung with dextroposition of the heart (Figure 3). Electrophysiological study was performed after obtaining written informed consent and discontinuation of all drugs for five half-lives.
