“…Therefore, it is possible that increased both local and systemic inflammation following surgery may play a role in the development of PE and cardiac tamponade. Mechanical valves can promote both systemic and local inflammation, represented by serum inflammatory markers such as IL-6 [13], and metallosis of the adjacent tissue [14]. Infective endocarditis is undoubtedly proinflammatory in status [15].…”

This study aimed to investigate the incidence, predictors, and clinical outcomes of cardiac tamponade after heart valve surgery. A total of 556 patients who underwent heart valve surgery in a single tertiary center between January 2010 and March 2012 were studied. All patients underwent transthoracic echocardiography (TTE) about 5 days after surgery and TTE was repeated regularly. Patients with suspected acute pericardial hemorrhage were excluded. Cardiac tamponade occurred in twenty-four (4.3%) patients and all underwent surgical or percutaneous pericardial drainage. The median time of pericardial drainage after surgery was 17 (interquartile range, IQR, 13–30) days. Infective endocarditis, mechanical valve replacement of aortic or mitral valve, and any amount of pericardial effusion (PE) on the first postoperative TTE were related to the occurrence of cardiac tamponade (all p<0.05). After multivariate adjustment, occurrence of cardiac tamponade was associated with any amount of PE on the first postoperative TTE (hazard ratio, HR, 14.00, p<0.001) and mechanical valve replacement (HR 2.69, p = 0.025). The mean hospital days in patients with cardiac tamponade was higher than those without (34.9 vs. 13.5, p = 0.031). After pericardial drainage, there was no echocardiographic recurrence of significant PE during a median of 34.8 (IQR 14.9–43.7) months after surgery. Cardiac tamponade after heart valve surgery is not uncommon. Patients with any amount of PE at the first postoperative TTE or mechanical valve replacement should receive higher attention with regard to the occurrence of cardiac tamponade. Although it prolongs hospital stay, cardiac tamponade exhibits a benign clinical course without recurrence after timely intervention.

“…The precise identification of the anatomical components of the right atrioventricular valve is important, considering its application in malformation diagnosis (Cave, 2001; Aldelfinger et al., 2003), surgery of injured or unhealthy valve replacements (Den Otter, 1972; Liu and Tilley, 1976; Northway, 1980; Breznock, 1994), surgical treatment of flutter (Racker et al., 1991), xenografting (Coffman et al., 1998), in the always remembered possibility of the use of the cusps in heterotransplantation (Margaglia et al., 1968) and xenotransplantation in the human valvulopathies. Thus we found an opportunity to study about the right atrioventricular valve components in dogs through the same criterion used for the human valve.…”

An anatomical study of the tricuspid valve was performed in the hearts of 45 dogs using a method of dissection which preserves the integrity of the valve. Morphometrical criteria such as the width of the cusp base and larger depth of cusp and morphological criteria such as the number of tendinous cords, the perimeter of the fibrous ring and the properties of the papillary muscle were adopted for the characterization of a cusp. The tricuspid valve was not consistent with three cusps, but it was observed to present 2, 4 or 5 cusps in 68% of the cases.
