The right ventricle may be the seat of ventricular tachycardia of left bundle branch block pattern. Recent interest has centred on its pathophysiology because early reports suggested that an apparent absence of gross organic heart disease indicated a more favourable prognosis. The term ‘arrhythmogenic right ventricular cardiomyopathy’ was first proposed in 1977 by Fontaine et al. when he reported right ventricular tachycardia associated with right-sided structural disorders. Although ARVC/D is a cardiomyopathy affecting primarily the right ventricle (RV), the left ventricle (LV) is also affected in many patients. It is a heterogeneous group of conditions characterized by right ventricular dysfunction and dilatation from very subtle abnormalities located at the RV to a most extensive RV and LV dysfunction.

Overall Mortality

SummaryBetween February 1986 and December 1991, 41 patients with pulmonary atresia and intact ventricular septum were treated in our institution following a multistage protocol of management. In all cases, the first step was to construct a right modified Blalock-Taussig shunt during the neonatal period regardless of the right ventricular anatomy. Then, in patients with well-developed right ventricles possessing all three components, we proceeded to early surgical repair. In contrast, in patients with right ventricles having obliteration of some components, yet deemed to be recoverable, the next step was to provide palliative relief of obstruction in the right ventricular outflow tract followed, if possible, by subsequent repair. Fontan's operation was performed in patients with right ventricles considered unsuitable from the outset to support the pulmonary circulation. Only one patient died following the initial shunt procedure (mortality of 2.43%). The subsequent program of treatment has now been concluded in 22 patients. In all those deemed to have favorable native anatomy (10 cases), the subsequent complete repair was successful. Among the 24 patients who required palliation of the outflow tract, five died while total repair was subsequently performed in eight. Fontan's operation was performed without mortality in five patients with small right ventricles, although one patient died while waiting for surgery. In all, 89 procedures were performed with an overall mortality of 14%.
