This procedure usually gives an excellent result which allows the patient to be free of symptoms and complications for an average of 5 to 10years and thus be free from the problems and complications that can arise from a surgical placement of a metal valve.

Percutaneous transvenous mitral commissurotomy (PTMC) is one of the nonsurgical commissurotomy in patients with hemodynamically significant mitral stenosis. The aim of the present study is to assess the immediate, intermediate and long term outcomes ...

Percutaneous transcatheter mitral commissurotomy (PTMC) What is PTMC? PTMC (or mitral balloon valvuloplasty) was developed in the 1990s as treatment for mitral stenosis (a narrowed mitral valve). Since this time, as the prevalence of rheumatic heart disease has declined in the developed world, the procedure has been performed less frequently. Dr Smith and his team…

Rheumatic heart disease and its impact on cardiac health is still a concern in developing countries. Percutaneous trans-mitral commissurotomy (PTMC) is the standard of care in managing severe rheumatic mitral stenosis (MS). This article reports a ...

Pre and post procedural Echocardiography evaluation: 2D echo, colour flow mapping and MVA calculation using planimetry was done before and after PTMC to evaluate MVA, and MR. A trans-oesophageal echocardiography (TEE) was done one day before the PTMC to rule out the presence of LA and left atrial appendage thrombus.

Percutaneous transvenous mitral commissurotomy (PTMC) is the therapy of choice for patients with mitral stenosis who are candidates for commissurotomy. PTMC also offers palliative therapy for patients who are not good surgical candidates. …

Poly(trimethylene carbonate) (PTMC) is an aliphatic polycarbonate synthesized from the 6-membered cyclic carbonate, trimethylene carbonate (1,3-propylene carbonate or 1,3-Dioxan-2-one). Trimethylene carbonate (TMC) is a colorless crystalline solid with melting point ranging between 45°C and 48 °C and boiling point at 255°C (at 760 mmHg). TMC is originally synthesized from 1,3-propanediol ...

Jul 23, 2021 · Selection of a patient for PTMC is based upon both clinical and anatomical factors (Table 23.1).It is usually indicated in a symptomatic patient with MVA <1.5 cm 2 and favorable valve anatomy. In general, PTMC is contraindicated if the MVA is >1.5 cm 2 or if there is LA thrombus, absence of commissural fusion, commissural calcification, more than mild mitral regurgitation, or associated ...
