Fontan completion in patients with complex cardiac anatomy, and specifically heterotaxy syndrome, can present unique physiologic considerations. For example, existing venous connections may be "unmasked" after a cavopulmonary anastomosis operation. We present the case of a child with heterotaxy, dextrocardia, single-ventricle physiology, and anomalous hepatic venous drainage that resulted in profound shunting and cyanosis. We addressed the problem utilizing a novel strategy with a "fenestrated" covered stent...

BACKGROUND: Dextrocardia with situs inversus is a rare cardiac positional anomaly. Catheter ablation procedures performed in this set of patients are not sufficiently reported. METHODS: A total of 10 patients with dextrocardia and situs inversus, who received catheter ablation for supraventricular tachycardia (SVT), were included from a cohort of over 20,000 cases of catheter ablation for SVT in 3 centers from 2005 to 2016. All patients underwent electrophysiologic study and catheter ablation of SVT...

Kartagener's syndrome is a rare genetic disorder of ciliated epithelial cells associated with recurrent respiratory tract infections, bronchiectasis, and situs inversus. In some patients the accumulation of airway secretions and recurrent infections lead to end-stage lung disease, for which lung transplantation (LT) is the only effective treatment. Anatomical variations, such as dextrocardia and pulmonary situs inversus, make the procedure challenging, yet feasible with certain technical modifications and careful preparation of donor lungs...

Septum primum malposition defect is an extremely rare CHD and is often found in patients with visceral heterotaxy, particularly of the polysplenia type. We describe a unique patient with dextrocardia, situs inversus totalis, and bilateral superior vena caval veins without heterotaxy syndrome who was diagnosed with an interatrial defect and partial anomalous pulmonary venous drainage due to malposition of the septum primum.

Congenital heart defects (CHD) are the most common congenital malformation reported in the literature, with a global incidence of eight per every 1,000 live births. In the United States approximately 40,000 infants are born each year with a CHD. Of the infants diagnosed with a CHD, one in every four heart defects are life threatening in origin. Early identification and treatment of congenital heart lesions, beginning with a comprehensive physical assessment after birth, are critical. For infants delivered at community-based hospitals, the importance of the physical assessment, timing of diagnostic strategies, anticipatory planning, and interprofessional collaboration among referring and accepting centers cannot be understated...

Implantation of a cardiac resynchronization therapy (CRT) device in patients with congenital heart disease may be challenging because of the particular underlying anatomy. We present the case of a right-sided transvenous implantation of a dual-chamber CRT-D device in a patient with situs inversus totalis and mirror image dextrocardia. To facilitate our anatomic orientation and to overcome unusual hand-eye coordination problems, we decided to flip the fluoroscopic image projection by 180° (right-left), creating the optical impression of a "normalized" heart position (levocardia)...

A pouch protruding from the free wall of the left ventricle may be either a congenital ventricular diverticulum (CVD) or aneurysm (CVA). Being aware of these rare congenital anomalies is critical in making the diagnosis. Differentiating the two is important for treatment decisions. We describe a patient with dextrocardia, Tetralogy of Fallot, and a congenital left ventricular apical diverticulum diagnosed following the induction of anesthesia. CVD and CVA may present in the antenatal period through late adulthood with differing morphology, location, and symptoms...

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.
