Congenitally unguarded tricuspid valve (TV) orifice, a variant of TV dysplasia, is a rare malformation with protean manifestations. This report describes a symptomatic adult male with gross right heart failure and atrial fibrillation, who was found to have an unguarded TV orifice with isolation of the trabecular apical cavity of the right ventricle (RV) and muscular ridges separating outflow tract (forme-fruste of the double-chambered RV). The right ventricular outflow tract remained patent.

For the treatment of structural heart disease, current options in the catheterization laboratory include MitraClip® implantation for treating severe mitral regurgitation, transcatheter aortic valve implantation (TAVI), closure of a patent foramen ovale (PFO) and occlusion of the left atrial appendage (LAA). These treatment options are based on a precise diagnosis provided by modern cardiac imaging, which is indispensable for treatment recommendations. Its importance for supporting the invasive procedures in the catheterization laboratory is less well known...

Evidence-based diagnosis, decision-making, and therapy appear a must these days. Generating and publishing evidence is a tedious job according to ever new and tightened research practice regulations. Rules will never prevent the typical human behaviour from showing the new thing to be shinier and the old thing dustier than they really are. The medical community is solicited to concoct a meal that is gullible for patients, authorities, and third-party payers out of the available evidence (after applying some conversion factors correcting the common bias of the researchers), anticipation of what will be the evidence tomorrow, common sense, and digested experience...

BACKGROUND: The regulatory T cell (Treg) is essential for prevention of autoimmunity. In a preliminary study, we showed significant deficiency of Tregs (CD4CD25 T cells) in rheumatic heart disease (RHD) patients (an autoimmune disease), but the markers used could not reliably differentiate Treg from nonregulatory conventional T cells (Tcon). The study aim was to reassess the level of circulatory Tregs by using more specific markers. METHODS: 70 adults of RHD and 35 controls were studied...

Hospital volume is regarded amongst many in the medical community as an important quality metric. This is especially true in more complicated and less commonly performed procedures such as structural heart disease interventions. Seminal work on hospital volume relationships was done by Luft et al more than 4 decades ago, when they demonstrated that hospitals performing > 200 surgical procedures a year had 25%-41% lower mortality than those performing fewer procedures. Numerous volume-outcome studies have since been done for varied surgical procedures...

PURPOSE: To describe and prove the concept of a technique for complete transapical deployment of a single-branch aortic arch endograft in a porcine model. METHODS: Eight domestic pigs underwent antegrade transapical delivery of a single-branch arch endograft, including a mating stent-graft to the innominate artery. Technical feasibility, operating time, radiation parameters, and hemodynamic changes were studied according to a standardized protocol during baseline (T0), after establishing the transapical access and through-and-through wire (T1), and after stent-graft deployment (T2)...

In an era when less invasive techniques are favored, therapeutic cardiac catheterization constantly evolves and widens its spectrum of usage in the pediatric population. The advent of sophisticated devices and well-designed equipment has made the management of many congenital cardiac lesions more efficient and safer, while providing more comfort to the patient. Nowadays, a large variety of heart diseases are managed with transcatheter techniques, such as patent foramen ovale, atrial and ventricular septal defects, valve stenosis, patent ductus arteriosus, aortic coarctation, pulmonary artery and vein stenosis and arteriovenous malformations...

BACKGROUND: Redo mitral valve surgery in patients with patent coronary bypass grafts carries a risk of graft injury and postoperative bleeding. We compare early results of reoperative minimally invasive on-pump beating heart mitral valve surgery (OPBMS) via mini thoracotomy vs the results of standard sternotomy mitral valve surgery (SSMS) in the presence of patent coronary bypass grafts. METHODS: Between 2009 and 2015, 12 patients underwent OPBMS through a right mini thoracotomy and 6 patients underwent SSMS...
