WINTER, José Luis et al. Spontaneous rupture of tricuspid valve papillary muscle in pulmonary hypertension secondary to HIV infection.Report of one case. Rev. méd. Chile [online]. 2014, vol.142, n.2, pp.246-249. ISSN 0034-9887.

Acute primary tricuspid regurgitation (TR) secondary to papillary muscle rupture is an extremely rare clinical situation. We report a 42-year-old male with pulmonary artery hypertension (PAH) secondary to HIV infection, who presented with an acute TR due to spontaneous papillary muscle rupture. He remained in cardiogenic shock despite therapy with inotropic drugs and pulmonary vasodilator therapy. He was subjected to a tricuspid valve replacement. In the postoperative period the patient had severe PAH, which was successfully controlled with inhaled nitric oxide. Tricuspid valve replacement and adjunctive use of pulmonary vasodilator therapy can be a life saving and useful approach in this condition.
