Double-chambered right ventricle: surgical experience and anatomical considerations.

Fourteen patients with double-chambered right ventricle underwent surgical treatment and repair of associated anomalies. The anomalous muscle band was isolated in 5 cases, associated with membranous ventricular septal defect in 7, with discrete sub-aortic stenosis in one and with double outlet right ventricle in one. All patients survived. The obstructing muscular band was a hypertrophic structure identifiable either with a displaced moderator band, still related to the anterior papillary muscle, or with a giant septoparietal band, inserting to the anterior free wall and occasionally present in normal hearts. According to this interpretation, referring the obstructive band to the septomarginal complex, double-chambered right ventricle should not be regarded strictly as a truncoconal malformation.

The usefulness of the phonocardiography in the diagnosis of the extrinsic obstruction of the pulmonary artery. Report of a case (author's transl).

The Authors describe a case in which an anterior mediastinal tumor manifested as a cardiovascular disease. Phonocardiographic findings and their modifications induced by respiratory manoeuvres are presented and discussed. Particular enphasis is given to the disappearance, with deep inspiration, of the pulmonary ejection murmur associated with the simultaneous paradoxical behaviour of pulmonary component of the second sound. The Authors suggest that such findings can be indicative of pulmonary outflow obstruction by an external mass.

Palliative surgery for single ventricle heart malformations.

During a 6-year period, 24 patients, aged 7 days to 18 years, underwent palliative surgery for single-ventricle heart malformations; 22 has single-left ventricle with outlet chamber (14 with L-transposition); only two had type C malformation (van Praagh). They were subdivided according to physiology into two groups: the first included 15 patients with decreased pulmonary blood flow, whose main clinical feature was arterial desaturation; the second consisted of nine patients with increased pulmonary blood flow, who presented early with unmanageable heart failure. The first group was treated with a Blalock-Taussig shunt (typical or modified) in 12 cases (one death due to preoperative acute renal failure), with a Waterston or Potts shunt in two cases (both died early postoperatively), and by enlargement of the bulbo-ventricular foramen in one (who died at operation). No late deaths were seen and the clinical status of the survivors is judged optimal. Patients of the second group received a pulmonary artery banding plus a number of associated procedures: coarctation repair (2), ligation of a patent ductus arteriosus (2), Blalock-Hanlon atrial septectomy (1), tricuspid valve replacement (1). There was only one early death due to critical subaortic stenosis produced by a restrictive outlet foramen; however, there were five late deaths and two cases of surgical failure with persistent pulmonary hypertension. An analysis of the best palliative approach in patients with single-ventricle heart malformations is made, based upon the results of this series and taking into consideration the possibility of future intracardiac repair.
