BACKGROUND: The Senning and Mustard operations for DTGA are associated with a heightened risk for supraventricular tachycardia. Catheter ablation has been shown to be acutely successful for achieving rhythm control in this population, but the mechanisms of recurrence are ill-defined. OBJECTIVES: We hypothesized that the type and degree of recurrence would vary by the surgical technique employed. METHODS: All consecutive catheter ablation procedures for DTGA after Mustard/Senning operation between 2004 and 2016 at a single center were reviewed...

BACKGROUND: Few centers for open heart surgery (OHS) are in Sub-Saharan Africa. Lack of OHS results is also noted. By reporting our African experience on OHS, the aim of this study was to fill the gap. METHODS: It is a retrospective study on 2,612 patients who were subject to an OHS between 1978 and 2013. Data were collected from demographical, clinical, investigative studies, surgical and outcomes parameters. RESULTS: There were 1,475 cases of rheumatic heart diseases (RHD), 126 endomyocardial fibrosis (EMF), 741 congenital heart diseases (CHDs) and 270 various affections...

The atrial baffle repair (ABR) significantly improved the fate of patients with transposition of the great arteries (TGA). However, these patients show impaired exercise tolerance and some present severe decline of systemic ventricular function. Intrinsic myocardial weakness, low heart rate response to exercise and diastolic filling impairment are discussed to be causative. Forty-nine long-term survivors with TGA (median age 23.7 year) after ABR were catheterized with measured oxygen consumption in four conditions (baseline, volume, atrial pacing, dobutamine) and the results were compared to 10 normal controls...

OBJECTIVE: To evaluate the mid-term outcomes of the correction of various congenital heart defects through a right subaxillary thoracotomy. METHODS: Between June 2004 and April 2014, all eligible patients were those with a common congenital heart defect corrected via an approach through a right subaxillary thoracotomy. There were 836 patients (male 417, female 419; median age, 3.5 years; median weight 13.6kg) with ventricular septal defect (VSD) closure (523 patients), atrial septal defect (ASD) closure (235 patients), partial atrioventricular canal (PAVC) correction (55 patients), mild tetralogy of Fallot (TOF) (23 patients)...

Left ventricular assist device (LVAD) implantation is a well-established therapy to support patients with end-stage heart failure. However, the operative procedure is associated with severe trauma. Third generation LVADs like the HeartWare assist device (HeartWare, Inc., Framingham, MA, USA) are characterized by enhanced technology despite smaller size. These devices offer new minimally invasive surgical options. Tricuspid regurgitation requiring valve repair is frequent in patients with the need for mechanical circulatory support as it is strongly associated with ischemic and nonischemic cardiomyopathy...

Iatrogenic occlusion of the right coronary artery (RCA) is a rare complication after tricuspid valve surgery. We review the case of a 74-year-old female who presented for mitral and tricuspid valve annuloplasty. Unanticipated postcardiopulmonary bypass biventricular hypokinesis was encountered, necessitating extracorporeal support. Emergent coronary angiography demonstrated near-complete RCA occlusion from a taut periarterial suture near the RCA. Deployment of a drug-eluting stent restored normal flow, and the patient made a full recovery...

Edge to edge transcatheter mitral valve repair with MitraClip (Abbott Vascular, Menlo Park, CA) is increasing for high-risk surgical patients with significant mitral regurgitation. Patients with congenitally corrected transposition of the great arteries (CCTGA) presenting with tricuspid valve regurgitation of a systemic right ventricle may represent particularly challenging candidates for MitraClip given their anatomy. We report the case of a 67-year-old gentleman with CCTGA and severe tricuspid regurgitation who was referred for MitraClip implantation after heart team consensus...

Objetive: Saline-irrigated radiofrequency ablation, which has been widely used for surgical treatment of atrial fibrillation in recent years, is 80-90% successful in achieving sinus rhythm. In our study, our surgical experience and mid-term results in patients who underwent mitral valve surgery and left atrial radiofrequency ablation were analyzed. Methods: Forty patients (15 males, 25 females; mean age 52.05±9.9 years; range 32-74) underwent surgery for atrial fibrillation associated with mitral valvular disease...

Percutaneous radiofrequency perforation (RFP) of the pulmonary valve is used as a primary therapy in neonates with pulmonary atresia and intact ventricular septum (PAIVS). We sought to determine the safety and efficacy of RFP for PAIVS in a single center and assess the pre-intervention anatomical parameters associated with a biventricular outcome. We retrospectively reviewed all cases of PAIVS treated with RFP at a single center from 1999 through 2012. We collected baseline imaging data, technical aspects of the procedure, adverse events and outcomes...

BACKGROUND: The aim of this study was to determine optimal patient selection and selection of a prosthetic ring size for tricuspid valve (TV) repair at the time of mitral valve (MV) repair. METHODS: We prospectively enrolled 167 consecutive patients undergoing MV repair. TV repair was indicated if patients had at least one of the following conditions representing tricuspid annular dilatation: (1) tricuspid regurgitation (TR)≥moderate, (2) history of right heart failure, (3) atrial fibrillation, and (4) pulmonary hypertension...

OBJECTIVE: The need for biological markers of aortic wall stress and risk of rupture or dissection of ascending aortic aneurysms is obvious. To date, wall stress cannot be related to a certain biological marker. We analyzed aortic tissue and serum for the presence of different MMP-2 isoforms to find a connection between serum and tissue MMP-2 and to evaluate the potential of different MMP-2 isoforms as markers of high wall stress. METHODS: Serum and aortic tissue from n = 24 patients and serum from n = 19 healthy controls was analyzed by ELISA and gelatin zymography...

Temporary tricuspid valve detachment improves the operative view of certain congenital ventricular septal defects (VSDs), but its long-term effects on tricuspid valve function are still debated. From 2002 through 2012, we performed a prospective study of 68 children (mean age, 1.28 ± 1.01 yr) who underwent transatrial closure of VSDs following temporary tricuspid valve detachment. Sixty patients had conoventricular and 8 had mid-muscular VSDs. All were in sinus rhythm. Seventeen patients had systemic pulmonary artery pressures...

In recent decades, significant progress has been made in the diagnosis and management of congenitally corrected transposition of the great arteries (ccTGA). Nevertheless, gradual dysfunction and failure of the right ventricle (RV) in the systemic circulation remain the main contributors to mortality and disability for patients with ccTGA, especially after adolescence. Anatomic repair of ccTGA effectively resolves the problem of failure of the systemic RV and has good early and midterm results. However, this strategy is applicable primarily in infants and children up to their teens and has associated risks and limitations, and new challenges can arise in the late postoperative period...

Parachute valve is the malformation of an atrioventricular valve in which the tension apparatus springs from a single papillary muscle or group of muscles. Parachute tricuspid valve is a rare anomaly with no surgically repaired case to date. We describe a case of parachute deformity of the tricuspid valve leading to hemodynamically significant severe tricuspid stenosis. The present case was successfully repaired surgically along with atrial septal defect (ASD) and ventricular septal defect (VSD) closure.

BACKGROUND AND OBJECTIVES: The aim of the study is to evaluate the long-term results after a surgical repair of Ebstein's anomaly. SUBJECTS AND METHODS: Forty-eight patients with Ebstein's anomaly who underwent open heart surgery between 1982 and 2013 were included. Median age at operation was 5.6 years (1 day-42.1 years). Forty-five patients (93.7%) demonstrated tricuspid valve (TV) regurgitation of less than moderate degree. When the patients were divided according to Carpentier's classification, types A, B, C, and D were 11, 21, 12, and 4 patients, respectively...

We present the primary report of a paediatric patient who had placement of the MitraClip device for severe functional mitral regurgitation. The patient was a 14-year-old boy with symptomatic end-stage non-compaction type cardiomyopathy secondary to a mitochondrial cytopathy. He had severe mitral regurgitation, tricuspid valve regurgitation, a severely dilated LV with apical non-compaction, severe LV dysfunction and severe pulmonary hypertension. Despite optimal medical therapy he developed progressive symptoms of congestive heart failure and he was not a candidate for an assist device or cardiac transplantation...

OBJECTIVES: Favourable outcomes in the repair of Ebstein's anomaly are predicated on tricuspid valve competence, right ventricular function and presence of arrhythmia. We report our experience with a single-stage, three-fold repair of Ebstein's anomaly, namely, cone reconstruction of the tricuspid valve supplemented by bidirectional cavopulmonary anastomosis and right atrial electrocautery maze. METHODS: From 2010 to 2014, 37 consecutive patients with Ebstein's anomaly, median age 17...

In chronic myeloid leukemia (CML), the occurrence of blastic transformation is rare. Treatment outcome is generally poor. Allogeneic stem cell transplantation (allo-SCT) is the only potentially curative treatment option for advanced-phase CML. Infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) isolates are associated with high morbidity and mortality rates, particularly in patients with haematological malignancies. Infection and colonization by these multiresistant bacteria may represent a challenge in SCT recipients for the management of post-transplantation complications, as well as for the eligibility to receive a transplant in patients who acquire the pathogen prior to the procedure...
