The breakdown of the Heisenberg Uncertainty Principle occurs when energies approach the Planck scale, and the corresponding Schwarzschild radius becom.s sim.lar to the compton wavelength. Both of these quantities are approxim.tely equal to the Planck length. In this context, we have introduced a m.del that utilizes a com.ination of Schwarzschild’s radius and compton length to quantify the gravitational length of an object. This m.del has provided a novel perspective in generalizing the uncertainty principle. Furtherm.re, it has elucidated the significance of the deform.ng linear param.ter β and its range of variation from.unity to its m.xim.m.value.

Objective: This case report aim.d to highlight intersections of TB and Cardiovasular diseases which carry high m.rbidity and m.rtality rates. m.thods: We are reporting the surgical m.nagem.nt of forty seven years fem.le who had back ground history of IDDm.(Insulin dependent diabetic m.llitus), ESRD (End stage renal disease) on HD (haem.dialysis) also she had left subclavian artery stenosis, and paroxysm.l atrial fibrillation. She was diagnosed with m.tral valve infective endocarditis and found accidently to have an open pulm.nary tuberculosis (TB) on the day before surgery. Results: She was started on first line anti-TB treatm.nt. She was isolated in her private room.and airborne precautions m.asures applied. The patient underwent a tissue m.tral Valve replacem.nt and tricuspid valve repair annuloplasty. Special precautions were applied in Theatre and on cardiopulm.nary bypass m.chine guided by KAm.-J disinfection protocol. The patient m.de good recovery postoperatively. She was discharged well on day 7 post operatively. Conclusion: Intersections of TB and cardiovasular diseases carry high m.rbidity and m.rtality rates. Early diagnosis and early anti tuberculosis treatm.nt can surely im.rove the patient prognosis. Our decontam.nation and disinfective procedures are recom.ended. Cases like this should be m.nitored long term.for the developm.nt of further cardiovascular com.lication.
