Abstract Background The mitral valve shows significant involvement in hypertrophic obstructive cardiomyopathy (HOCM). The mid-term outcomes of management of HOCM by prosthetic valve replacement with septal myectomy remain unclear. This study compared the prognosis of patients with and without prosthetic valve replacement. Methods From 01/2009 until 10/2015, 24 patients with HOCM underwent septal myectomy with or without valve repair/replacement were recruited. A total of 23 patients underwent echocardiographic evaluation before and after the operation. The follow-up duration ranged from 0.4 to 7 years (median 2.5 years). The Kaplan-Meier test was used to explore the association between prosthetic valve replacement and overall/disease-free survival among HOCM patients. Results A total of 9 patients underwent septal myectomy with/without mitral valve repair (MVr), and the other 15 patients underwent septal myectomy with mitral valve replacement (MVR). Six patients treated with MVR had unfavorable outcomes, including one peri-operative and three late deaths; one patient suffered from aborted sudden death, and one patient was treated for prosthetic valve endocarditis. Prosthetic valve replacement was associated with poor disease-free survival (p = 0.025). Conclusions Septal myectomy with or without-MVr was associated with a better outcome than septal myectomy with MVR in HOCM patients. The differences in prognosis were caused by more complicated left ventricular outflow tract structures and more prosthetic valve complications among patients undergoing MVR.

This retrospective study attempted to establish the prevalence of multiple-valve involvement in Marfan syndrome and to compare echocardiographic with histopathologic findings in Marfan patients undergoing valvular or aortic surgery. We reviewed echocardiograms of 73 Marfan patients who underwent cardiovascular surgery from January 2004 through October 2009. Tissue histology was available for comparison in 29 patients. Among the 73 patients, 66 underwent aortic valve replacement or the Bentall procedure. Histologic findings were available in 29 patients, all of whom had myxomatous degeneration. Of 63 patients with moderate or severe aortic regurgitation as determined by echocardiography, 4 had thickened aortic valves. The echocardiographic findings in 18 patients with mitral involvement included mitral prolapse in 15. Of 11 patients with moderate or severe mitral regurgitation as determined by echocardiography, 4 underwent mitral valve repair and 7 mitral valve replacement. Histologic findings among mitral valve replacement patients showed thickened valve tissue and myxomatous degeneration. Tricuspid involvement was seen echocardiographically in 8 patients, all of whom had tricuspid prolapse. Two patients had severe tricuspid regurgitation, and both underwent repair. Both mitral and tricuspid involvement were seen echocardiographically in 7 patients. Among the 73 patients undergoing cardiac surgery for Marfan syndrome, 66 had moderate or severe aortic regurgitation, although their valves manifested few histologic changes. Eighteen patients had mitral involvement (moderate or severe mitral regurgitation, prolapse, or both), and 8 had tricuspid involvement. Mitral valves were most frequently found to have histologic changes, but the tricuspid valve was invariably involved.

A seven-year-old Shih Tzu with refractory repeated pulmonary edema and syncope was presented for surgical operation. From the results of cardiovascular examinations, the dog was diagnosed as severe mitral regurgitation (ACVIM consensus class D) and mild tricuspid regurgitation. The dog first underwent surgery with mitral valve plasty; however, the results were unsatisfactory due to severe damage of the whole mitral valve. The operation was quickly changed to mitral valve replacement using a mechanical valve (19 mm). The dog survived surgery and lived for 2 years and one month after operation using long-term anticoagulant (warfarin) therapy in spite of several thrombosis-related events.
