Glutaraldehyde-fixed autologous pericardium rarely calcifies or retracts, and it is a useful substitute for cardiac valve leaflets. Current understanding of aortic valve geometry provides good models for aortic leaflet design, and pericardial leaflet construction is illustrated in this article for bicuspid and tri-leaflet valves. Outcomes have been characterized by low valve-related complication rates, and results of recent series are encouraging. Perhaps sufficient data are available to consider autologous pericardial leaflet replacement in highly selected younger patients with irreparable leaflets and contraindications to warfarin.

Background: Left atrial dissection is a rare and occasionally fatal complication of cardiac surgery and is defined as the creation of a false chamber through a tear in the mitral valve annulus extending into the left atrial wall. Some patients are asymptomatic, while others present with various symptoms, such as chest pain, dyspnea, and even cardiac arrest. Although there is no established management for left atrial dissection, surgery should be considered in patients with hemodynamic disruption.

Background: Atrial flutter (AFL) is usually effectively treated by cavotricuspid isthmus (CTI) ablation. If AFL recurs despite ablation, there is risk of progression to atrial fibrillation (AF) and clinicians should consider underlying structural heart diseases. This consideration becomes especially critical when right-heart-chambers are dilated.

The autologous pericardial aortic valve repair technique developed by Ozaki et al., using glutaraldehyde-treated autologous pericardium, has demonstrated superior durability to bioprosthetic valves. However, this technique has certain limitations, including excessive cusp height and cusp fluttering due to leaflet redunduncy.

Reoperations can be challenging for patients who experience left and right atrioventricular valve failure after repair of a complete atrioventricular septal defect. Herein, we present a case of a 10-year-old boy who developed dysfunction in left and right atrioventricular valve following surgery for a complete atrioventricular septal defect. The patient underwent successful replacement of his left atrioventricular valve with a mechanical valve due to severe stenosis.

Objective: Annuloplasty is the most common strategy for repair of functional tricuspid regurgitation (FTR) but is not effective in patients with massive/torrential FTR or leaflet tethering. To address the deficits of tricuspid annuloplasty, TRicuspid Anterior and Posterior Patch (TRAPP) repair was developed, which is a pericardial patch augmentation of the anterior and posterior leaflets.
Methods: To test this repair, a previously validated ex vivo model in an explanted porcine heart was used, wherein annular and leaflet geometry were evaluated using a 3-dimensional structured light scanner at 4 time points: (1) baseline, (2) induction of FTR, (3) annuloplasty repair, and (4) patch repair.
