BACKGROUND: Nowadays, Tricuspid valve replacement (TVR) is much less common than aortic or mitral valve replacement, since repair is almost always preferable. Prosthetic tricuspid valves are associated with high mortality and morbidity, mostly due to thrombotic or hemorrhagic events. Nevertheless, there is lack of evidence of which is the optimal type of valve (biological versus mechanical) in tricuspid position. METHODS: We analysed all the patients who underwent TVR in our Institution, from 2005 to 2015...

AIMS: So far, a total of five patients with eclipsed mitral regurgitation (MR) have been reported in the literature by three different teams. The aim of this article was to detail clinical and echocardiographic characteristics, and outcome of patients presenting eclipsed MR. METHODS AND RESULTS: We defined eclipsed MR as spontaneous appearance, at rest, from 1 min to the next of an acute restriction in the motion of mitral leaflets preventing coaptation and leading to massive MR in patients with normal left ventricular end-diastolic diameter, left ventricular ejection fraction >45%, and baseline MR ≤2...

OBJECTIVE: Shone's syndrome is a complex consisting of mitral valve stenosis in addition to left ventricle outflow obstruction. There are a few studies evaluating the long-term outcomes in this population. We sought to determine the long-term outcomes in our paediatric population with Shone's syndrome and the factors associated with left heart growth. METHODS: All patients diagnosed with Shone's syndrome with biventricular circulation treated between 1978 and 2010 were reviewed...

A 67-year-old patient with rheumatic heart valve disease had undergone two cardiac surgeries at the age of 30 years, then re-do with mitral valve replacement at 50 years. She presented with congestive heart failure and hemolytic anemia. Doppler echocardiography showed moderate-severe mitral regurgitation due to paravalvular mitral valve leak (PVML) and severe pulmonary hypertension. Transesophageal echocardiography demonstrated severe PVML secondary to a large 20 mm-long PVML defect. Due to comorbidities, the heart team deemed a third reoperation at very high surgical risk; therefore, the patient was considered most suitable for a transcatheter approach to PVML closure...

A 33-year-old male was admitted to the hospital for a repeat mitral valve replacement. The original surgery, performed in India in 2008 due to rheumatic heart disease, required massive amounts of plasma replacement during and after the surgery. The patient was admitted to our hospital with extremely low Factor V and Factor VIII activities due to a rare combined Factor V and Factor VIII deficiency. His clinical condition on admission was grave due to severe pulmonary hypertension. It was decided to replace the patient's Factor V using therapeutic plasma exchange (TPE) with fresh frozen plasma (FFP) just prior to surgery, and his Factor VIII with Factor VIII concentrate...

Valvular heart disease (VHD) is caused by either damage or defect in one of the four heart valves, aortic, mitral, tricuspid or pulmonary. Defects in these valves can be congenital or acquired. Age, gender, tobacco use, hypercholesterolemia, hypertension, and type II diabetes contribute to the risk of disease. VHD is an escalating health issue with a prevalence of 2.5% in the United States alone. Considering the likely increase of the aging population worldwide, the incidence of acquired VHD is expected to increase...

BACKGROUND AND OBJECTIVE: Pulmonary hypertension (PH) is a progressive disorder that can be caused by several underlying conditions or an intrinsic alteration of the pulmonary vasculature. Chronic increased pressure in the pulmonary vasculature leads to changes in the architecture of the vessels that can perpetuate PH and produce right ventricular dysfunction. These structural and functional alterations can decrease survival and quality of life of patients on hemodialysis; however, there is a lack of evidence about this problem in this population...

Lesions of the heart valves are the commonest acquired cardiac abnormalities seen in pediatric age group. In India, the underlying cause for most valvular diseases is chronic rheumatic heart disease (RHD). The aim of evaluation of patients with valvular heart disease is not only to make a diagnosis, but also to decide the management plan. The pediatrician or physician is usually the first health care provider to whom such patients (or their parents) report. It is therefore imperative that the general physician and pediatricians are well versed with valvular heart diseases...

As a salvage strategy, extracorporeal membrane oxygenation (ECMO) permits the recovery of end-organ perfusion, whilst allowing the surgeon time for patient reassessment and surgical planning. We report upon the first known case in which VA ECMO was instituted as peri-operative supportive therapy for a young patient, in-extremis, with surgically correctable Chronic Thromboembolic Pulmonary Hypertension (CTEPH) and Hypertrophic Cardiomyopathy (HOCM).
