A 59-calendar year-previous male with a past health-related background of a repaired ventricular septal defect (VSD), dextrocardia, hypertension, hyperlipidemia, and existing smoker offered to the emergency division (ED). This affected person experienced identified coronary artery condition (CAD), and previously required drug eluting stents to the obtuse marginal and diagonal arteries. The affected person expressed epigastric pain, nausea, and exhaustion followed by non-exertional, regular ideal-sided chest suffering with radiation to his right arm.
The patient initially offered to an outside the house ED and was subsequently transferred to our facility for continuity of treatment. Affected individual had stable critical signals with an oral temperature of 36.4 levels Celsius, coronary heart charge of 91, blood pressure of 118 around 76, respiratory rate of 23, and pulse ox of 96 % on area air. He was asymptomatic upon presentation.
A standard, remaining-sided EKG was in the beginning acquired, which demonstrated inverted P waves in lead I, deep Q waves in guide V1, detrimental QRS advanced in V1, and RBBB. It was quickly discerned that the patient experienced dextrocardia from prior records, and an EKG for dextrocardia was attained.
The 2nd EKG was regarding for STEMI in the precordial potential customers (see figure 1). The patient’s initially and second troponins from the outside medical center were being considerably less than .01 ng/mL. The 3rd troponin at our facility resulted as better than 50.00 ng/mL. The patient was started out on IV heparin and right away taken for cardiac catheterization.
In the cath lab, the affected person was discovered to have evidence of a proximal thrombus and major stenosis of the LAD (see figure 2). He underwent profitable revascularization and stenting of the proximal to mid LAD.

Dextrocardia is a unusual congenital anomaly where the coronary heart is intrinsically positioned in the proper hemithorax with the apex pointing in the direction of the proper caudal position.1 It has a prevalence of .01 per cent.1 Dextrocardia can be connected with an over-all situs inversus, where all inside organs are in the reversed position or be minimal to situs ambiguous, in which only some organs are in the reversed.1
Irrespective of the rarity of dextrocardia, coronary artery condition can occur with a equivalent frequency to that of the normal population.3 Coronary artery illness in a client with Dextrocardia can current with distinct findings on a standard left-sided EKG that increase suspicion for this anomaly. Nevertheless, there could be diagnostic dilemmas if these results are not instantly recognized. This hold off in recognition can final result in the inadvertent underdiagnosis of STEMIs. As a result, it is vital to figure out dextrocardia and alter our diagnostic resources properly.
Dextrocardia with STEMI is a rare clinical presentation that presents with both diagnostic and complex difficulties. A literature research by way of PubMed yielded less than 80 situation studies of this presentation. Additional, sufferers with dextrocardia could have atypical displays of STEMIs. Dextrocardia can have features of right axis deviation, positive QRS complexes (upright P and T waves) in aVR, detrimental P and T waves and QRS complexes in direct I, and absent R wave development in the precordial leads with dominant S waves.4 In conditions of dextrocardia, precordial prospects must be put in a mirror impression on the appropriate side of the chest, as is completed for a right-sided EKG, with the extra reversal of the correct and still left limb potential customers.4
Signs or symptoms of acute coronary syndrome classically present on the remaining chest wall, even so, our patient’s pain was all localized to the appropriate side of the upper body, which has been explained with other cases of dextrocardia.5 The patient’s original remaining-sided EKG did not display about ST segment modifications. On the other hand, the affected individual experienced identified dextrocardia centered on documented professional medical background and was confirmed with a current chest x-ray. On the prompt reversal of EKG qualified prospects for dextrocardia, the individual was located to have an noticeable STEMI in the precordial qualified prospects. The affected person was then emergently taken for cardiac catheterization. It is significant to discern cardiac anomalies, these kinds of as dextrocardia, early in a patient’s scientific presentation, as it can significantly effect the timely interpretation of EKGs and the appropriate administration of the patient’s care.
