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...

A total of 39 titles related to rheumatic fever or rheumatic heart disease in Malaysia were found with online literature search dating back to their inceptions and through 2014. Additional publications from conference journals were included. Nine papers were selected based on clinical relevance and future research implications. There were no population-based studies on the incidence or prevalence of ARF or RHD. In the 1980s, the incidence of admission due to ARF ranged from 2 to 21.1 per 100 000 paediatric admission per year...

A 24-year-old otherwise healthy man presented with a 3-week history of malaise, headache, fever and rigors after he was treated with oral clindamycin for left parotitis and Gemella haemolysans bacteraemia. He developed G. haemolysans infective endocarditis, septic emboli and heart failure due to progressive bivalvular disease. He underwent urgent mechanical aortic valve replacement and mitral valve repair, which required venovenous extracorporeal membrane oxygenation, to support severe respiratory failure. This is the first documented case of G...

Mitral regurgitation (MR) is the most common valvular heart disease in the Western world. The MR can be either organic (mainly degenerative in Western countries) or functional (secondary to left ventricular remodeling in the context of ischemic or idiopathic dilated cardiomyopathy). Degenerative and functional MR are completely different disease entities that pose specific decision-making problems and require different management. The natural history of severe degenerative MR is clearly unfavorable. However, timely and effective correction of degenerative MR is associated with a normalization of life expectancy...

The average age of patients undergoing mitral valve repair is increasing each year. This retrospective study aimed to compare postoperative complications of mitral valve repair (known to be especially high-risk) between 2 age groups: under and over the age of 80.Patients who underwent mitral valve repair were divided into 2 groups: group 1 (<80 years old) and group 2 (≥80 years old). Baseline characteristics, pre- and postoperative hemodynamic data, surgical characteristics, and postoperative follow-up data until hospital discharge were collected...

A 4-year-old boy had a 15-mm atrial septal defect repaired percutaneously with use of an Amplatzer Septal Occluder. At age 16 years, he presented with a week's history of fever, chills, dyspnea, fatigue, and malaise. Cultures grew methicillin-sensitive Staphylococcus aureus. A transesophageal echocardiogram showed a 1.25 × 1.5-cm pedunculated mass on the left aspect of the atrial septum just superior to the mitral valve, and a smaller vegetation on the right inferior medial aspect of the septum. At surgery, visual examination of both sides of the septum revealed granulation tissue, the pedunculated mass, the small vegetation, and exposed metal wires that suggested incomplete endothelialization of the occluder...

BACKGROUND: Previous clinical experiences have demonstrated high early and late recurrence rates after repair of functional tricuspid regurgitation (TR). We investigated the results of functional TR repair with undersized rigid nonplanar annuloplasty rings. METHODS: From January 2007 to December 2013, 216 consecutive patients with moderate or greater functional TR were treated with undersized (size 26 mm or 28 mm) rigid nonplanar annuloplasty rings. RESULTS: The mean age was 69 ± 13 years...

A 59-year-old man was admitted with a 3-month history of daily fevers as well as bilateral knee pain and swelling. Medical history was significant for bilateral knee arthroplasties 4 years prior to admission. Two sets of peripheral blood cultures as well as bilateral knee synovial fluid grew Enterococcus faecalis within 10 hours. Transoesophageal echocardiography revealed aortic and mitral valve vegetations suggestive of infectious endocarditis, with severe regurgitation secondary to large size. The patient's hospitalisation was complicated by acute heart failure, necessitating emergent mitral valve repair and aortic valve replacement, followed shortly thereafter by bilateral total knee arthroplasty resection with placement of antibiotic spacers...

BACKGROUND: A patient with a history of mitral valve prolapse and regurgitation that was corrected with a mitral ring repair 15 years earlier received a diagnosis of anomalous left coronary artery arising from the pulmonary artery and underwent repair. DISCUSSION: Coronary computed tomography angiography (CTA) was employed to image the patient before surgical intervention. Synchronizing contrast media administration to opacify the right coronary artery in the arterial phase and the left coronary artery in the venous phase required a test-bolus approach...

We aimed to develop a method that provides an alternative cannulation site in robotic mitral valve surgery that allows simultaneous endo-occlusion and antegrade perfusion. A 71-year-old man with severe mitral regurgitation and history of coronary artery bypass grafting underwent totally endoscopic robotic mitral valve repair. A 23-mm endoreturn cannula was placed through a 10-mm graft that was sewn to the left axillary artery. An endoballoon was passed through the Dacron/cannula complex and into the ascending aorta...

Gebode defect, that can accurately be treated surgical repair, is defined as a true communication between left ventricle and right atrium. A 74-year-old woman with a worsening history of ortophnea and peripheral edema was hospitalised. A communication between right atrium and left ventricle was diagnosed using transeusophageal echocardiography. The defect was repaired and mitral valve was replaced with a biologic valve. It would be beter to tailor surgical strategy for each case with atrioventricular canal defect after preoperative transeusophageal echocardiography and peroperative direct sight...

A 31-year-old Argentinian woman presented with a 3-week history of fever, night sweats, myalgia and lethargy following a work trip to Uganda where she ran a marathon. Malarial screens were negative but C reactive protein, erythrocyte sedimentation rate and neutrophil count were raised and she was anaemic. A new pansystolic murmur was heard over the mitral valve and the transthoracic echocardiogram showed a large vegetation (>1 cm) with at least moderate mitral regurgitation. Blood cultures grew Neisseria elongata, subsp elongata treated initially with ceftriaxone then oral ciprofloxacin to complete 4 weeks of treatment...

Cardiovascular impairments are frequent in Cushing's syndrome and the hypercortisolism can result in cardiac structural and functional changes that lead in rare cases to dilated cardiomyopathy (DCM). Such cardiac impairment may be reversible in response to a eucortisolaemic state.A 43-year-old man with a medical past of hypertension and history of smoking presented to the emergency department with global heart failure. Coronary angiography showed a significant stenosis of a marginal branch and cardiac MRI revealed a nonischemic DCM...

Complications of transseptal puncture are significant and potentially life threatening. Aortic perforation is one of these complications and it needs to be repaired immediately. We report the case of a 48-year-old female with a history of rheumatic mitral valve disease. She underwent three previous mitral valve replacements. Her last echocardiogram reported an anterolateral leak in the mitral prosthesis. Catheterization was performed. During the procedure, when attempting to perform transseptal puncture, catheterization was complicated by a forcefully puncture of the aortic root by the Brockenbrough needle followed by an immediately advancement of an 8-Fr Mullins sheath...

In contrast to mitral regurgitation (MR) caused by structural abnormality of the valve ("primary" MR), about which there is increasing consensus regarding treatment, there is increasing controversy around the management of functional or "secondary" MR, of which "ischemic mitral regurgitation" (IMR) is a common cause. While the trend in the management of primary MR is increasingly aggressive, with wide agreement on the preference for repair over replacement such that debate centers on earlier and earlier repair even among asymptomatic patients, the situation is reversed in the setting of secondary MR with uncertainly beyond the mode of management (repair or replacement) to the value of intervening at all...

AIM: Several tools have been invented for surgical atrial fibrillation (AF) ablation. In this study, we investigated the real world efficacy of intraoperative AF ablation (AFA) with radiofrequency-energy or cryo-ablation and performed an electro-anatomical remap in some patients with recurrences. METHODS: Seventy-three consecutive patients (53 male, median age of 69 ± 7 years) with history of AF underwent cardiac surgery for valve repair (74 % mitral defects, 60 % aortic defects) and/or coronary artery bypass graft procedures (56 %)...

A 42-year-old woman presented with a 6-month history of palpitations and progressive dyspnea on exertion. She had undergone aortic and mitral valve repair using glutaraldehyde-treated autologous pericardium for active infective endocarditis 5 years prior. Transthoracic echocardiography showed mitral valve stenosis with limited movement of the anterior leaflet. At redo surgery, severe calcification of the glutaraldehyde-treated pericardial patch on the anterior mitral leaflet was observed. Double valve replacement was performed with pulmonary vein isolation...
