INITIAL AND FOLLOW-UP RESULTS OF PTCA AND PTMC

On the bases of the initial and follow-up results of patients who underwent percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transvenous mitral commissurotomy (PTMC), the proper applications of these interventional therapies were discussed.
The efficacy of PTMC on valvotomy was comparable to open mitral commissurotomy and the procedural safety was noticed. Out results supported the use of PTMC for patients with plicable mitral valve.
Desipite the good and acceptable results of elective PTCA, low initial success rate and high incidence of major cardiac events including mortality was noted in the group of urgent PTCA for patients with multivessel lesions. The urgent use of PTCA for refractory unstable angina should be restricted to selected patients without high-risk multivessle lesions.
