Dextrocardia is a congenital anomaly where the heart is abnormally located in the right hemithorax. In these patients, the implementation of transvenous implantable cardioverter-defibrillator (TV-ICD) can be technically challenging and pose a higher risk of complications than the general population. We present the case of a male patient that was successfully submitted to right-sided implantation of subcutaneous ICD (S-ICD) as an alternative to transvenous ICD (TV-ICD) for primary prevention of sudden cardiac death...

BACKGROUND: A right-sided heart (RSH) has three main causes: dextrocardia, dextroposition and dextroversion. It may be associated with cardiac malformation, extra-cardiac abnormalities and adverse patient outcomes. The aim of this study was to determine the prevalence, demographics, associated cardiac malformations (ACM) and outcome of paediatric patients diagnosed with a RSH at a South African tertiary hospital. METHODS: A retrospective review was performed over a 22-year period...

Chromosome 1q21.1 deletion syndrome is associated with a wide variety of clinical features including mild to moderate mental retardation, microcephaly, cardiac abnormalities, and cataracts. We report an unusual case of a premature neonate with persistent hyponatremia, markedly elevated plasma arginine vasopressin level (32.7 pg/mL), and clinical findings consistent with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). The patient, who also had microcephaly and dextrocardia, was subsequently diagnosed with chromosome 1q21...

BACKGROUND: Studies on dextrocardia have been limited by low numbers. Hence, it is very difficult to find the most common diagnosis in patients with dextrocardia, who are seeking medical attention in tertiary care center. AIMS AND OBJECTIVE: To identify the most common diagnostic pattern in patients with dextrocardia with different situs. METHODS: It is a retrospective study with records dating back to up to last 21 years from a major tertiary care center in south India...

A 51-year-old male with dextrocardia and situs inversus underwent catheter ablation for paroxysmal atrial fibrillation. Because the procedure through the trans-septal approach was impossible due to the inferior vena cava continuity with azygos vein, we performed pulmonary vein isolation using magnetic navigation system through the retrograde trans-aortic approach. Superior and inferior left-sided and superior right-sided pulmonary veins could be isolated which was confirmed by the ablation catheter. The patient was free from atrial fibrillation episode at the 12 months follow-up except only one palpitation episode lasting nearly 12 hours at 9 months after the ablation...

Transcatheter heart valve-in-valve implantation in failed surgical bioprosthetic valves has shown promising outcomes, prompting the stepwise expansion of their applications in different clinical scenarios. Recently, there is increased interest in valve-in-valve techniques for the treatment of patients with complex congenital heart disease. Herein, we report a case of successful transapical transcatheter atrioventricular valve-in-valve implantation in a patient with Fontan circulation and dextrocardia. The patient was previously treated with total cavopulmonary connection and atrioventricular valve replacement with recurrent prosthesis dysfunction...

Transcatheter aortic valve implantation (TAVI) has evolved into a standard therapy for aged patients with severe aortic valve stenosis who are not candidates for surgery. However, the reports about the safety of TAVI for patients with dextrocardia situs inversus are few. An 84-year-old man with dextrocardia situs inversus underwent a TAVI for severe aortic stenosis (AS) with an aortic valve area of 0.5 cm2 , and a mean pressure gradient of 46 mmHg. Preoperative computed tomography (CT) revealed an inverted (rightward) orientation of the ventricle apex as well as the great vessels...

Acute myocardial infarction in dextrocardia may present several challenges either in electrocardiographic diagnosis or coronary intervention or both, due to abnormal location of the heart, mirror images o the aorta and its branches, and abnormal coronary origin and orientation. Also, dextrocardia as a risk factor for coronary artery disease is less well established. We report the case of a young patient with dextrocardia and situs inversus without any risk factor who presented with acute extensive anterior wall myocardial infarction diagnosed after lead reversal and who successfully underwent coronary intervention using "double inversion technique"...

Knowledge of anatomy is vital preimplant to screen the patient for the subcutaneous implantable defibrillator (S-ICD), particularly those who have previously had thoracic surgery. X-ray screening in these patients is highly recommended.

The arterial switch operation is considered as standard therapy for isolated D-transposition of the great arteries. However, in under-developed countries, patients still present with D-transposition of the great arteries beyond the neonatal age redering them unsuitable for anatomical repair. These children are often offered physiological repair, i.e. Senning or Mustard procedure. We describe our experience of a successful Senning procredure in a 4.6-year girl, who had atrial and visceral situs inversus totalis, dextrocardia and d-transposition of the great arteries...

Infants with dextrocardia-heterotaxy syndrome pose significant surgical challenges to a successful orthotopic heart transplant. Here in we report two infants with dextrocardia-heterotaxy syndrome who underwent complex heart transplantation. A combination of pre-operative three-dimensional chest computed tomography to predict optimal donor size and unique surgical technique resulted in successful outcomes.

BACKGROUND: Situs inversus is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions. Situs inversus is found in about 0.01% of the population. In the most common situation, situs inversus totalis involves complete transposition (right to left reversal) of all of the abdominal organs. Several successful and safe laparoscopic weight loss surgeries were previously reported in morbidly obese patients with situs inversus (Aziret et al...

STUDY DESIGN: Retrospective cohort study, Level of Evidence III OBJECTIVE.: To determine the relationship between internal organ orientation and adolescent idiopathic scoliosis (AIS) convexity directionality SUMMARY OF BACKGROUND DATA.: AIS affects 2-3% of the general population and demonstrations 80-99% right thoracic curve convexity. The mechanism of AIS as well as explanation for right-sided predominance is largely unknown. METHODS: A retrospective chart review of all patients with dextrocardia from 2008-2018 was performed at a single institution...

This report presents the case of an 82 year old male with known dextrocardia and situs inversus totalis who developed increasing dyspnea on exertion and was diagnosed with severe aortic stenosis. Transcatheter aortic valve replacement was decided upon requiring deviation from standard techniques for patients with normal anatomy and left-sided aortic arch. We describe two technical differences required for patients with dextrocardia and right-sided aortic arch which facilitate transcatheter aortic valve replacement in this patient group...

RATIONALE: Tumor resection and extracranial-intracranial bypass concerning medial sphenoid ridge meningioma associated with severe stenosis of the internal carotid artery (ICA) of intracranial segments has been rarely presented. Effective treatment as to the complex lesions may be complicated. Tumor resection and cerebrovascular protection should be both taken into consideration. PATIENT CONCERNS: We presented one case of medial sphenoid ridge meningioma associated with severe stenosis of the internal carotid artery of intracranial segments...

Congenitally corrected transposition of the great arteries (CCTGA) should not be missed in patients with dextrocardia and situs solitus. We report a case of a 56-year-old man with late diagnosis of CCTGA after ventricular lead replacement. Free LV wall pacing may be favorable in these patients so to prevent deterioration of the systemic RV function.

It is quite unambiguous and interesting that postchemotherapy histology of hepatoblastoma may mimicry that of hepatocellular carcinoma which should be differentiated by proper immunohistochemistry and cytology, if possible, for further management and predict prognosis.
