Paravalvular leakage (PVL) is one of the most well-recognised complications of prosthetic valve replacement. The size of the leakage is usually about one to two stitches. We would like to introduce a new technique to manage this complication by using a folding pericardium patch, which can surely overcome the disadvantage of second-time valve replacement. By now, we have applied this new technique to at least four cases, all of them worked well. Thus, we present our new technique that can be considered as a good alternative management of intraoperative PVLs, especially in aortic position.

Treatment of hemodynamically significant mitral annular calcification (MAC) using transcatheter approaches is in the early learning phase. The occurrence of paravalvular leak (PVL) following transcath...
Paravalvular leak (PVL) is often seen after aortic (AV) and mitral valve (MV) surgery, either due to infection or valve dehiscence. We sought to describe predictors of longer-term outcomes in patients...
To evaluate the association between measurements performed during Medtronic CoreValve (MCV) deployment and paravalvular leak (PVL).
Paravalvular leak (PVL) is a condition that could be treated surgically or by the transcatheter deployment of the occluder devices (plugs). No PVL-specific occluder device is available on...
In approximately 10-15% of all patients after surgical or interventional heart valve replacement, flapping defects appear as complications in the long-term course, so-called paravalvular /...
The purpose of the study is to compare the maternal, fetal and neonatal outcomes of a cohort of 60 patients in whom a multilayer closure with a Durepair patch is performed with a prior coh...
The researchers are doing this study to find out whether there will be less increase in cardiac filling pressure after the surgeon opens the pericardium (the membrane around the heart) tha...
The injection of autologous blood Blood Patch (BP) into the epidural space is the standard treatment for headache associated with intracranial hypotension. It provokes cerebral vasoconstri...
An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used.
Inflammation of the PERICARDIUM that is characterized by the fibrous scarring and adhesion of both serous layers, the VISCERAL PERICARDIUM and the PARIETAL PERICARDIUM leading to the loss of pericardial cavity. The thickened pericardium severely restricts cardiac filling. Clinical signs include FATIGUE, muscle wasting, and WEIGHT LOSS.
A conical fibro-serous sac surrounding the HEART and the roots of the great vessels (AORTA; VENAE CAVAE; PULMONARY ARTERY). Pericardium consists of two sacs, the outer fibrous pericardium and the inner serous pericardium. The latter consists of an outer parietal layer facing the fibrous pericardium, and an inner visceral layer (epicardium) resting next to the heart, and a pericardial cavity between these two layers.
A medicated adhesive patch placed on the skin to deliver a specific dose of medication into the bloodstream.
Skin tests in which the sensitizer is applied to a patch of cotton cloth or gauze held in place for approximately 48-72 hours. It is used for the elicitation of a contact hypersensitivity reaction.
