Mitral regurgitation is the most common valvular heart disease. Its cause is most frequently functional or secondary dysfunction (functional mitral regurgitation, FMR) compared with degenerative mitral regurgitation (DMR), which is associated with decreased ventricular function, hospitalization for heart failure, and mortality. While medical treatment is effective over extended periods, a significant number of patients cannot...
Cardiogenic shock (CS) in a setting of aortic stenosis is associated with high mortality rates. In consequence, surgery is generally not a possibility for this patient group, and they usually undergo aortic valvuloplasty, resulting in a mortality rate of 33%-50% at 30 days, 70% at one year, and 90% at two years. While transcatheter aortic...
TLR associated factors in patients with calcified nodules. Patients with complex cardiomyopathies undergoing percutaneous coronary intervention are increasingly common, as is the case for calcified lesions and calcified nodules (CN). Procedure complexity not only involves planning, but also establishing patient prognosis, taking into consideration the fact that most target vessel events occur at long term...
Intravascular Ultrasound (IVUS) has shown, in several studies, its great benefits for both restenosis and mortality reduction. Even though several variables have been studied, so far minimal stent area (MSA) has been disregarded as important. The OPTIVUS-Complex PCI looked at 961 patients with 1,957 lesions, and found 1.6% TLR incidence (30 lesions). There were no...
In last few years, transcatheter edge-to-edge repair (TEER) with MitraClip has been shown safe and effective, both for primary and secondary mitral valve regurgitation (MR), given the increasing interventionist and echocardiographer experience. However, there is a group of patients that require surgery after failed TEER, either because of bad evolution or because device implantation...
Patients presenting aortic stenosis with cardiogenic shock are at extreme risk, with 70% mortality until the aortic obstruction is resolved, and taking into account they make poor transplant candidates. Safety and efficacy of TAVR in patients with cardiogenic shock remains unclear. The aim of this study was to assess events in patients undergoing TAVR with...
Coronary artery obstruction (CAO) after TAVR is rare, but it entails extremely high mortality (50% or more), especially after valve-in-valve (V-in-V) or when the coronary ostia are is too close to the valve annulus. This is why the BASILICA technique was developed (Bioprosthetic or Native Aortic Scallop Intentional Laceration to Prevent Iatrogenic Coronary Artery Obstruction)....
Deep vein Arterialization in patients with critical “non-revascularizable” limb ischemia. We are familiar with the poor quality of life and elevated mortality of patients with chronic limb-threatening ischemia (CLTI). In its last stages (nearly terminal), revascularization (either surgical or endovascular) has been shown to reduce amputation incidence. However, similarly to heart disease and other vascular scenarios,...
At present, surgical aortic valve replacement (SAVR) uses bioprostheses. However, when these fail, we are presented with a great challenge, seeing as repeat SAVR involves a higher risk. In this context, valve-in-valve (V-in-V TAVR) has surged as a very attractive alternative. Bioprosthesis fracture (BPF) is a new interesting strategy that has shown lower gradient and...
The safety and efficacy of transcatheter aortic valve replacement (TAVR) is already established. However, it still poses a challenge for conduction disturbances, such as the need for pacemaker or new onset left bundle branch block (LBBB). The current rate for the latter ranges from approximately 11% to 19%. In most cases, 50% of LBBB reverses...
