Unguarded tricuspid orifice is a very rare anomaly. It is characterised by the absence of one or more of the tricuspid valve leaflets resulting in severe tricuspid regurgitation and right heart failure. It is rarely an isolated anomaly but more often associated with pulmonary atresia and intact ventricular septum. When the ventricles are inverted however, the result of outflow tract obliteration is not pulmonary atresia, but aortic atresia. This anomaly has been described in the literature in only 2 cases so far. We present a case of a neonate with unguarded tricuspid orifice with absence of all tricuspid leaflets, congenitally corrected transposition of the great arteries and aortic atresia. The severe tricuspid regurgitation and right ventricular enlargement would have required a Norwood-like procedure combined with a right ventricular plication. Due to the complexity of this lesion no surgical therapy was attempted in consent with the parents.

Severe Tricuspid Regurgitation

Severe left ventricular volume overloading causes myocardial and cellular contractile dysfunction. Whether this is also true for severe right ventricular volume overloading was unknown. We therefore created severe tricuspid regurgitation percutaneously in seven dogs and then observed them for 3.5–4.0 yr. All five surviving operated dogs had severe tricuspid regurgitation and right heart failure, including massive ascites, but they did not have left heart failure. Right ventricular cardiocytes were isolated from these and from normal dogs, and sarcomere mechanics were assessed via laser diffraction. Right ventricular cardiocytes from the tricuspid regurgitation dogs were 20% longer than control cells, but neither the extent (0.171 ± 0.005 μm) nor the velocity (2.92 ± 0.12 μm/s) of sarcomere shortening differed from controls (0.179 ± 0.005 μm and 3.09 ± 0.11 μm/s, respectively). Thus, despite massive tricuspid regurgitation causing overt right heart failure, intrinsic right ventricular contractile function was normal. This finding for the severely volume-overloaded right ventricle stands in distinct contrast to our finding for the left ventricle severely volume overloaded by mitral regurgitation, wherein intrinsic contractile function is depressed.

Background: Percutaneous tricuspid valve leaflet repair is an emerging treatment option for severe tricuspid regurgitation (TR). Recent studies demonstrated the usefulness and feasibility of the lately introduced TriClip and PASCAL Transcatheter Valve Repair System. However, initial experiences regarding safety and efficacy of the novel transcatheter PASCAL Ace implant system have not yet been reported. Methods: Sixteen patients with severe, massive, or torrential TR underwent tricuspid leaflet repair using the PASCAL Ace implant at our cardiology department. All patients suffered from symptomatic right-sided heart failure with New York Heart Association functional class III or IV. Clinical, laboratory, echocardiographic, and procedural data were assessed. The primary efficiency end point was postprocedural reduction in TR of at least 1 grade. Secondary end points were feasibility, safety, clinical outcome, and improvement of structural and functional right heart parameters obtained by echocardiography. Results: Eleven procedures (69%) resulted in successful reduction of TR. In 4 patients, PASCAL Ace implantation was not successful and one patient did not achieve TR reduction despite PASCAL Ace implantation. One major bleeding related to the intervention occurred. Eight patients (73%) with successful TR reduction reported a significant improvement of New York Heart Association functional class 4 weeks after implantation ( P =0.008). A significant reduction in right atrial volume from 84±41 mL/m 2 to 69±36 mL/m 2 ( P =0.004) and right ventricular end-diastolic diameter from 50±7 mm to 47±8 mm ( P =0.013) was observed; however, we did not see an improvement in right ventricular function directly after implantation. Conclusions: Tricuspid valve leaflet repair using the transcatheter PASCAL Ace implant system has the potential to improve clinical status and right heart reverse remodeling in patients with severe TR.

We performed a combined Senning and arterial switch operation on a 2-month-old patient with congenitally corrected transposition, Ebstein's malformation producing severe tricuspid regurgitation, ventricular septal defect, pulmonary hypertension, and congestive heart failure. The tricuspid regurgitation was improved. The double switch operation has the advantage of improving the function of the systemic atrioventricular valve, especially in newborns or young infants in whom the outcome of the valvar repair is poor.

Severe Tricuspid Regurgitation

The presence of pulsating varicous veins is an uncommon finding, generically attributed to right heart failure. The precise causes of this phenomenon have been poorly defined in the literature. The finding of this infrequent condition is important because it may be a sign of major diseases, often not known. Here we described a 75-year-old woman presented to the Angiology Unit for the presence of bilateral pulsatile swelling in her groin and along both lower limbs. A bedside ultrasound examination showed an arterial like pulsating flow both in the superficial and in the deep veins of the lower limbs due to a severe tricuspid regurgitation not previously known.
