Arteriovenous fistulae (AVFs) constructed for hemodialysis access are prone to aneurysmal degeneration. This can lead to life-threatening sequelae such as aneurysmal rupture. The literature includes various guidelines on the management of certain aspects of access-related aneurysm formation; however, no classification system exists to guide reporting or prognostication. We aimed to ...

Persistent fifth arch (PFA) is a rare anomaly that is often underdiagnosed and missed. Different PFA types that have been reported in the literature are systemic-to-systemic type (most common), systemic-to-pulmonary artery (PA), and PA-to-systemic types. The designations of systemic-to-PA or PA-to-systemic are based on if the PFA is a source ...

Although mitral valve prolapse as a disease entity has been recognized for over 50 years, its precise definition has been elusive. Initial reports based the diagnosis on auscultatory findings (late systolic click - murmur), with left ventricular angiography as a confirmative test. Echocardiography, first the M-mode, and subsequently the two-dimensional, ...

Triangular leaflet resection to treat posterior mitral valve prolapse is expedient, sufficient, and durable in eliminating redundant myxomatous tissue and restoring normal leaflet coaptation. After triangular resection and suture reconstruction, mitral scallop height is decreased to a degree commensurate with the area of tissue resected. There are instances however, when ...

A nonresectional technique has been developed for repair of mitral leaflet prolapse causing mitral regurgitation. Polytetrafluoroethylene chordae are used for correction of edge misalignment of the prolapsed mitral leaflet. New chordal length is adjusted during progressive left ventricular inflation to systolic pressure. Annular sizing is determined dynamically after leaflet edge ...

Quadrangular resection is the gold standard in the treatment of posterior leaflet prolapse. Anterior leaflet prolapse has been considered a more challenging problem; several techniques are available to treat it, all with the same goal - mitral valve competency. Nowadays, good long-term results are reported, similar to those for posterior ...

A 35 years old second gravida was admitted to our department with acute pulmonary oedema after labor. Echocardiography disclosed an intra-atrial membrane prolapsing through the mitral valve in diastole, with two small orifices creating a mean pressure gradient of 7.9mmHg. However the membrane clearly originated away from the mitral valve ...
