ABSTRACT

Surgical correction of anomalous pulmonary venous connection from the left lung to the innominate vein (through a vertical vein) without cardiopulmonary bypass, was performed in two patients, with excellent evolution. After median sternotomy, the ascending vertical vein was cut obliquely close to the vein, and connected to the left atrial appendage. In the postoperative period, the patients were in NYHA class I and the hemodynamic study showed normal venous drainage from the left lung to the left atrium.

ABSTRACT

A new technique is proposed for mitral incompetence due to elongated chordae tendineae of the anterior leaflet. It consists in shortening the chordae tendineae of the leaflet level. First, we make a longitudinal orifice in the anterior leaflet just near its free edge and the elongated chordae tendineae. Through the orifice and with the help of a micro nerve hook we pull the elongated chordae the necessary to keep the anterior leaflet in the same level of the posterior leaflet. The orifice is then closed with a polipropilene 5-0 suture. The mitral annuloplasty was performed with a Gregori IMC prosthetic ring. The excellent clinical and laboratorial data suggest that mitral insufficiency due to elongated chordae tendineae can be corrected by this technique.

ABSTRACT

Prolapse of the anterior leaflet of the mitral valve is the result of ruptured chordae, elongated chordae, or elongated or ruptured papillary muscle. Several techniques have been described for the correction of mitral valve insufficiency. However, when there is severe rupture of the chordae, the most widely accepted solution is valve replacement. We describe a technique for the creation of a neochorda with a strip of tissue from the anterior leaflet of the mitral valve. This technique was used in two patients with severe mitral valve regurgitation. Formation of a neochorda and placement of a Carpentier ring to remodel the anulus obviated the need for a valve replacement. Both patients had an uneventful recovery. Studies performed 3 and 4 months postoperatively showed competent and well-functioning valves. One patient required a valve replacement for acute mitral insufficiency 5 years later, but the other patient was doing well 3 years after the operation. Despite the limited experience, we believe this technique offers a reasonable alternative to valve replacement.
