Background: Percutaneous mitral valvuloplasty (PMV) is still the treatment of choice in selected cases of mitral stenosis (MS). Multitrack balloon (MTB) catheter is one of the techniques used for PMV with optimal results. We describe a novel refinement of appropriate balloon sizing and wire placement to reduce mitral regurgitation (MR) and Left ventricular (LV) apical perforation, respectively.
Methods: Ninety four consecutive patients with moderate to severe rheumatic mitral stenosis (MS) were selected for PMV with MTB catheter. Balloon sizing was done by effective balloon dilatation area (EBDA), using standard geometric formula. 0.35" PMV wire was placed in aortic arch /ascending aorta (AA) to avoid LV apical perforation.
Results: Mild MR was present in 28(29.8%). Post-procedure MR was present in 50(53.2%). Out of 50 MR cases 44(88%) had mild and 6(12.0%) had moderate MR. No patient had severe MR. With placement of wire in AA and arch of aorta none of the patients developed complication of LV apical perforation.
Conclusion: EDBA as balloon sizing for multitrack system can be used to reduce severity of mitral regurgitation. Placement of PMV guide wire in Aortic arch/AA ascending aorta can eliminate/substantially reduce dreadful complication of LV perforation.

Background: Cryoballoon ablation is less operator-dependent than radiofrequency ablation. Recently, size-adjustable cryoballoons (SA-CBs) have become available. We sought to analyze the individual baseline operator experience's impact on procedural results.

Transcatheter pulmonary valve implantation (TPVI) is the standard of care in patients with repaired tetralogy of Fallot (rTOF) presenting with right ventricular outflow tract (RVOT) dysfunction. However, the feasibility of TPVI is limited by the high cost and nonavailability of larger-sized valves for dilated native RVOT of rTOF patients. We report the first successful TPVI with a custom-made 35 mm balloon-expandable valve (Myval™) in a 30-year-old rTOF patient with severe pulmonary regurgitation and RV dysfunction.

Article Synopsis
- The study investigates the double-balloon technique's effectiveness in reducing aortic regurgitation (AR) after balloon aortic valvotomy (BAV) in children, with a focus on short- and mid-term outcomes.
- Out of 50 patients (average age 6.5 years), 34% had prior AR, and after the procedure, there was a significant decrease in peak-to-peak gradient and only 20% experienced trivial AR post-BAV, while none had severe AR.
- The technique was found to be safe, with no deaths or emergency surgeries required, suggesting it could be a promising alternative for larger patients, although further long-term studies are needed.
Modest dilation using rotational atherectomy and drug-coated balloon for native coronary proximal lesion with patent internal thoracic artery graft.

Unlabelled: Intervention to proximal lesions should be avoided in graft-protected native coronary arteries in general, because there might be a risk for bypass-graft failure. An 81-year-old man with coronary artery bypass grafting surgery due to 3-vessel disease 17 years previously complained of worsening angina. Coronary angiography (CAG) revealed a diseased saphenous vein graft (SVG) and a probable functional occlusion in the mid left anterior descending coronary artery (LAD) concomitant with calcified severe stenosis in the left main (LM)-proximal LAD, and patent right internal thoracic artery (RITA)-LAD graft.

Evidence supports that intravascular imaging-guided PCI offers advantages over conventional angiography-guided PCI, though its use is limited, likely due to high costs. Angiography-guided PCI relies on visual estimation, leading to inter- and intra-observer variability and suboptimal outcomes.
