A lesion ≥50% in the left main coronary artery (LMCA) is considered severe, according to various scientific societies, regardless of the presence of symptoms or ischemia, due to the extent of myocardium at risk. In such cases, revascularization is indicated. In many patients, lesions in this section of the coronary artery have severe calcification, which...
Over time, percutaneous coronary intervention (PCI) with drug coated balloons (DCB) have been shown more beneficial than conventional PCI. However, in many cases, stenting is required to treat suboptimal results. Even though several studies have looked into this scenario, long term durability still calls for research. This was a 5 year thorough analysis of the...
Proximal optimization technique (POT) has been recommended as a standard strategy in bifurcation lesions because it facilitates proper stent implantation and apposition in the proximal main vessel, according to the European Bifurcation Club. Percutaneous coronary intervention (PCI) of the unprotected left main coronary artery (LMCA) has specific characteristics, and the long-term impact of this strategy...
TAVR is a well-established course of treatment, increasingly indicated in lower risk populations. However, one of the challenges associated with self-expanding TAVR, compared against balloon expandable TAVR and SAVR, is the frequent need for definite permanent pacemaker implantation (PPI). High implantation, also known as cusp overlapping (COT), has been shown to reduce the need for...
Complementary imaging allows for the identification of numerous scenarios not visible with conventional angiography (ICA), both for the assessment of differential diagnoses and the improvement of percutaneous coronary intervention (PCI) outcomes. Advantages include assessment of plaque characteristics, vessel plaque burden, stent edge dissection, vessel diameter, and correct apposition, among others. While intravascular ultrasound (IVUS) was...
The edge-to-edge approach with MitraClip has been established as a valid strategy for patients who experience severe symptomatic mitral regurgitation (MI) with high risk for surgery, currently with a IIa indication. MI complicated by cardiogenic shock, which results in a high risk for conventional valve surgery, is a particularly complex scenario. In such a case,...
Several scientific societies support performing left atrial appendage occlusion (LAAO) as a stand-alone procedure, even though it is often associated to other cardiomyopathies requiring transcatheter intervention. Though still controversial, combining LAAO and any other cardiac intervention might reduce hospitalizations, as well as the need for additional punctures, anesthesia, red tape, a longer stay and higher...
Transcatheter aortic valve replacement (TAVR) has widely demonstrated its significant benefits, both in high-risk and inoperable patients, as well as in those with intermediate and low risk. While paravalvular regurgitation has been a challenge, its management has improved with operator experience and a deeper understanding of CT angiographies. However, in cases of regurgitation, elevated gradient,...
Failure of a mitral bioprosthesis always poses a challenge regarding decision-making, especially when dealing with elderly patients with multiple risk factors. The scenario is worsened by the high risk associated with a new sternotomy and the significant impact of undergoing new surgery. Transcatheter mitral valve-in-valve (TMViV) replacement is emerging as a valid strategy in the...
Severe mitral disease is common and currently constitutes a frequent cause of hospitalization and death. While surgery is the treatment of choice, transcatheter mitral valve replacement (TMVR) emerges as a valid alternative in cases of bioprosthesis failure, ring malfunction, or severe mitral annular calcification (MAC). Furthermore, the latest medical guidelines support the recommendation of TMVR...
