Intermittent acute porphyria (IAP) is an inborn metabolic disorder of biosynthesis of haeme, characterized by increased excretion of porphyrin or porphyrin precursor in urine and clinically by gastrointestinal, neuro-psychiatric and cardiovascular manifestations. Significant observations were made on echocardiographic examination of 25 IAP patients in our study. Significant decrease in ejection fraction (48.4 +/- 7.9, control group 63.0 +/- 7.5, P < 0.001) and percentage of fractional shortening (23.5% +/- 6.87%, control group = 36.4 +/- 4.26, P </=.001) was observed in IAP, this shows derangement in left ventricular systolic functions in IAP. The study also shows significant thickening of IVS (1.22 +/- 0.20, control group 0.88 +/- 0.12 cm, P </= 0.001). The most interesting finding was the significantly increased incidence of mitral valve and/or tricuspid valve prolapse in 15 (60%) patients of IAP. Thickening of AML, PML, and calcification of AML were also observed.

Mitral valve prolapse may involve 1 leaflet or 2 leaflets, yet management guidelines do not differentiate posterior leaflet (PML) from bileaflet (BML) prolapse. We hypothesized that patients with BML have a prolonged natural history with more severe atrial and ventricular enlargement but less severe mitral regurgitation (MR) compared to patients with PML. Patients with mitral valve prolapse undergoing mitral repair were identified and preoperative characteristics were recorded. Patients with predominant PML prolapse (n = 304) versus BML prolapse (n = 131) were identified based on preoperative echocardiographic and intraoperative findings. Timing of operation was based on standard guidelines. Despite being equally symptomatic, patients with BML differed significantly from those with PML in being younger (54 vs 60 years, p <0.0001), more likely to be women (51% vs 24%, p <0.0001), and having a larger valve (37 vs 32 mm, p <0.0001). Despite similar cardiac function and dimensions, patients with BML had less severe MR (24% vs 13% with <4+ MR, p = 0.01) and less severe pulmonary hypertension (14% vs 31%, p <0.0001) at time of operation. In conclusion, patients with BML often meet indications for mitral valve repair with similar cardiac enlargement but less MR than patients with PML prolapse. Patients with BML prolapse may benefit from timing mitral repair based more on symptomatic 3+ MR or cardiac enlargement and less on presence of severe MR.
