IntroductionCarcinoid heart disease most frequently involves the tricuspid or, more
rarely, the pulmonary valve and presents with right heart failure as 5-HT is
metabolized by the lung. Left-sided valve involvement is quite rare. We
describe our experience of 3 patients presenting with heart failure
secondary to carcinoid heart disease affecting all four cardiac valves.
There are only four previous isolated case reports in the literature.MethodsAll three patients underwent quadruple valve replacement during a single
operation. Right ventricular outflow tract reconstruction with a pericardial
patch was performed in all patients. For 24 hours prior to surgery, all
patients received intravenous octreotide, which continued in intensive care
for at least 24 hours.ResultsMean cross-clamp and bypass times were 175 (range 164-197 minutes) and 210
(range 195-229 minutes) minutes, respectively. Mean intensive treatment unit
(ITU) and inpatient stays were 2.3 (range 2-3 days) and 12 (range 9-16 days)
days, respectively. One patient was reopened for bleeding 4 hours
postoperatively from a ventricular pacing wire site. None required a
permanent pacemaker postoperatively. There were no other complications in
any patient. The quality of life was excellent at 6-16 months clinic
follow-up as they were in NYHA 1. Postoperative echocardiography showed no
paravalvular leaks and well-functioning prostheses in all cases.ConclusionSurgery to replace all four valves is feasible with excellent medium-term
survival and a very low rate of complications. Patients with carcinoid heart
disease should always be considered for surgery irrespective of the extent
of valvular involvement.
