Patients with congenital d-transposition of the great arteries (d-TGA) undergoing palliative atrial baffle surgery in infancy often develop systemic ventricular failure in adulthood. If they undergo cardiac transplantation, they are prone to morphologic right ventricular (RV) failure secondary to severe pulmonary hypertension as a result of systemic ventricular failure. We ...

The rate of arteriovenous fistula (AVF) placement continues to rise and AVF failure is a major complication. The main cause of AVF failure is stenosis leading to thrombosis. Although the detection of early stenosis with preemptive correction prior to thrombosis seems to be a plausible option to prevent access failure, ...

Percutaneous pulmonary valve implantation (PPVI) has been established as a valuable treatment option for elder children and adolescents with conduit failure in the right ventricular outflow tract (RVOT). Transcatheter valve implantation in the tricuspid position is restriced to single case reports. A 26 year-old male initially diagnosed with tetralogy of ...

Outcome of bioprosthetic valve replacement in the tricuspid position in patients with kidney failure is unknown. The authors describe a case of accelerated bioprosthetic tricuspid valve calcification leading to critical stenosis in a patient on chronic dialysis and with poorly controlled hyperparathyroidism. He required a second valve replacement in less ...

Anomalies of the innominate vein are uncommon in congenital cardiac disease. We report a case of duplicate innominate veins forming a vascular ring encircling the ascending aorta. We postulate that this vascular ring represents the failure of both a dorsal and ventral precardinal anastomosis to regress.

Scorpion envenomation is common in tropical and subtropical regions. Cardio-respiratory manifestations, mainly cardiogenic shock and pulmonary edema, are the leading causes of death after scorpion envenomation. The mechanism of pulmonary edema remains unclear and contradictory conclusions were published. However, most publications confirm that pulmonary edema has been attributed to acute ...

Reflux of contrast medium into the inferior vena cava (IVC) is often detected on computerized tomographic pulmonary angiogram. The potential clinical implications and associated diagnoses of this finding have not been established. We investigated the prevalence and significance of reflux of contrast medium into the IVC in a large cohort ...

INTRODUCTION: Synchronous embolism to the superior mesenteric artery (SMA) and coeliac axis (CA) is a rare disease. REPORT: A 67-year-old man with atrial fibrillation developed acute liver failure due to an embolic occlusion of the CA and SMA, with a severe coagulation disorder. He was successfully managed with percutaneous stent ...

Arterial stiffness/elasticity plays a major role in the pathogenesis of heart failure beyond arterial blood pressure. Arterial wave reflections are generated from the periphery of the vascular system, especially at the level of the small arteries. The pattern change of the arterial wave reflections can alter the ventricular-vascular coupling in ...

BACKGROUND: Concomitant asymptomatic coronary artery disease in patients with Chagas cardiomyopathy in heart failure is controversial in the medical literature, as both diseases are prevalent in some regions of Brazil. OBJECTIVE: To determine the prevalence of coronary artery disease (lesions > 50%) in a specific population of patients with Chagas ...

We describe a case with partial analgesia after ultrasound-guided supraclavicular block for elbow surgery. The failure of the block was caused by the limited spread of local anesthetic because of blockage by a vessel (either transverse cervical artery or dorsal scapular artery) running through the brachial plexus. Anesthesiologists should be ...

BACKGROUND: Aortic stenosis is of concern in the elderly. Although aortic valve replacement provides good long-term survival with functional improvement, many elderly patients are still not referred for surgery because of their age. Percutaneous aortic valve implantation offers an alternative to open-heart surgery. Concerns about the management of aortic valve ...

Congenital heart diseases are corrected early in life, so the surgical procedure has to maintain the maximum potential for growth. The quest for the ideal material for cardiac tissue repair is still ongoing. Here, we describe our preliminary experience with an extracellular matrix for cardiac and vascular tissue repair. Between ...

Atrioventricular discordance with ventricular-arterial discordance is a rare cardiac anomaly known as congenitally corrected transposition of the great arteries (CCTGA). This malformation has a prevalence of 0.4-0.6% of all congenital heart disease cases. Complete heart block develops in up to 30% of patients with CCTGA. We present the case of ...

In cases of pulmonary atresia (PA) with ventricular septal defect (VSD), the commonest source of pulmonary blood flow is via major aortoplumonary collaterals. Collaterals may also arise from the coronary arteries and the reported prevalence of such coronary-pulmonary artery fistulas (CPAF) in PA with VSD is 10%. However gross congestive ...

Rupture of a sinus of Valsalva aneurysm (SVA) is clinically characterized by widening of an existing sinus of Valsalva aneurysm in time and its opening to other cardiac cavities, primarily to the right atrium and right ventricle. Increased biventricular filling appearing due to rupture causes symptoms of heart failure. Although ...

Anomalous aortic origin of the coronary artery is a rare cardiac anomaly which induces myocardial ischemia and is associated with sudden death. We operated on a 25-year-old female with syncopal episodes who had an intramural left coronary artery. A neo-ostium was created in the left sinus but the initial neo-ostium ...

A patent ductus arteriosus (PDA) is often present in patients undergoing correction of congenital heart disease. It is well appreciated that during cardiopulmonary bypass (CPB), a PDA steals arterial inflow into pulmonary circulation, and may lead to systemic hypoperfusion, excessive pulmonary blood flow (PBF) and distention of the left heart. ...

Pleural effusions commonly occur in patients with left heart failure. However, there is increasing evidence that patients with pulmonary hypertension and isolated right heart failure frequently have pleural effusions. Three recent studies have evaluated the incidence of pleural effusions without an alternate explanation in patients with idiopathic/familial pulmonary arterial hypertension ...

Mycotic aneurysm of the superior mesenteric artery (SMA) is one of the complications associated with infective endocarditis. However, there are no previous case reports in the literature describing mycotic SMA aneurysm after left ventricular assist device (LVAD) implantation. We describe the case of a 31-year-old male diagnosed with congestive heart ...

Giant cell arteritis involving intramural coronary artery branches is rare, and its clinical features remain poorly understood. We report a 56-year-old hemodialysed patient with a history of mitral valve replacement, who presented with "fever of unknown origin" and intractable hypotension. The antemortem diagnosis was very difficult and the autopsy revealed ...

Cardiac calcified amorphous tumors (CATs) can arise in all four chambers of the heart. Cardiac CATs can cause diverse symptoms according to their locations, and mass or embolic effects. Pulmonary emboli arising from cardiac CATs have been reported, but the true incidence is unknown due to their rarity. Herein we ...
