In the context of TAVR, one of the current challenges is the need for permanent pacemaker implantation (PPM), especially when using self-expanding valves (SEV). The information available in this regard remains controversial; while some studies suggest new PPM implantation will have no significant effect on clinical evolution, others have associated them with worse prognosis. As...
MyVal Device in Non-Calcified Severe Aortic Regurgitation
Due to the proven long-term results and substantial increase in the number of transcatheter aortic valve implantation (TAVI) procedures conducted, the application of TAVI has been extended to clinical situations outside the original scope, such as non-calcified aortic regurgitation (NCAR). Device placement in these new scenarios entails a technical challenge due to the absence of...
Predictors and Evolution of Permanent Pacemaker After TAVR with Self-Expanding Valves
Transcatheter aortic valve replacement (TAVR) has shown remarkable benefits and continues to advance towards lower-risk patients and younger ages. However, one of its limitations lies in the demand for a permanent pacemaker (PPM), which during TAVR early stages with self-expanding valves reached 30%. Uncertainty persists regarding the evolution of patients undergoing PPM implantation after TAVR,...
SOLACI-SBHCI 2023 Scientific Coverage – Day 3
The third day of the Congress started at the Copacabana Arena with the International Live Case held at Nanjing First Hospital, Nanjing, China, which showcased a successful and illustrative step-by-step Transcatheter Coronary Intervention (TCI) angioplasty with circulatory support and optimized results using Intravascular Ultrasound (IVUS) applicability. Following that, Dr. Fei Ye presented Intravascular Imaging and...
Opportunity for Fellows! 1 Year Training Program from McMaster University (Canada) – SOLACI Invitation
McMaster University in Canada, is developing a 1-year training program on imaging guided percutaneous coronary intervention (non-invasive cardiac CT, IVUS and OCT). From SOLACI, we extend the invitation to all Latin American fellows, since we consider this a unique opportunity to apply and be able to advance your careers in such a renowned institution of...
Post PCI Functional Assessment for Focal Lesion and Stent Underexpansion Detection
The use of fractional flow reserve (FFR) and non-hyperemic pressure indices (NHPRs) have become essential for intermediate lesion revascularization. A linear inverse correlation has been recently shown between the use of post PCI physiology and cardiovascular events at followup. However, its adoption has been limited so far, seeing the wide variety of algorithms used in...
TAVI in Moderate Aortic Stenosis with Low Ejection Fraction
The presence of aortic stenosis, heart failure, and decreased ventricular function is associated with poor prognosis and high mortality. For this reason, both European and American guidelines classify severe stenosis as a Class I indication. There are two retrospective analyses that demonstrate the benefits of transcatheter aortic valve implantation (TAVI) via transfemoral access. The TAVR...
Intrastent Restenosis in Ostial Lesions in the Right Coronary Artery: Predictors of an Unfavorable Location
Predictors of intrastent restenosis in the right coronary artery ostium. The ostium of the right coronary artery (RCA) presents certain histological aspects. Atherosclerotic and fibrotic plaques in this area contain an abundance of smooth muscle, collagen, and a certain degree of calcification, along with thicker adventitia. Additionally, it has certain anatomical aspects such as poor...
5 Year Evolution of PCI vs CABG in Large Randomized Studies on Acute and Chronic Coronary Syndrome
Left main lesions in acute coronary syndrome (ACS) represent a major risk and, at present, the best revascularization strategy is a matter of debate. Though many studies and registries have excluded this group of patients, there is data on the pros and cons of both percutaneous coronary intervention (PCI) and cardiac artery bypass graft (CABG). ...
Latest Developments in Tricuspid Regurgitation
The natural history of tricuspid regurgitation is associated to hospitalization for cardiac failure and mortality. This is why the AHA/ACC guidelines recommend surgery when the tricuspid fails during left valve surgical repair, because its slow progression is associated with high mortality (35%). Many of these patients are high risk and percutaneous intervention has surged as...
