Article Synopsis
  • Severe aortic stenosis (AS) leads to changes in the heart’s left ventricle and can affect blood flow and resistance in coronary arteries.
  • A study assessed coronary blood flow and microvascular resistance in AS patients before and after transcatheter aortic valve implantation (TAVI) and found no immediate changes right after the procedure.
  • Six months post-TAVI, patients showed significant improvement in hyperaemic perfusion, indicating that over time, left ventricular remodelling positively affected blood flow during increased demand.

Ischemic heart disease is currently the most common cause of mortality and morbidity worldwide. Although myocardial ischemia is classically determined by epicardial coronary atherosclerosis, up to 40% of patients referred for coronary angiography have no obstructive coronary artery disease (CAD). Ischemia with non-obstructive coronary artery disease (INOCA) has typically been underestimated in the past because, until recently, its prognostic significance was not completely clear.

Continuous Thermodilution is a novel method of quantifying coronary flow (Q) in mL/min. To account for variability of Q within the cardiac cycle, the trace is smoothened with a 2 s moving average filter. This can sometimes be ineffective due to significant heart rate variability, ventricular extrasystoles, and deep inspiration, resulting in a fluctuating temperature trace and ambiguity in the location of the "steady state".

Cardiovascular Center Aalst, OLV-Clinic, Aalst, Belgium; Department of Cardiology, Lausanne University Hospital, Lausanne, Switzerland. Electronic address:

Article Synopsis
  • The study aimed to compare two methods (continuous and bolus thermodilution) for measuring coronary flow reserve (CFR) and microvascular resistance reserve (MRR) in patients with chest pain and nonobstructive coronary artery disease.
  • Results indicated that mean CFR and MRR values were significantly higher when measured using continuous thermodilution compared to bolus thermodilution, with continuous allowing for greater precision and lower variability in the results.
  • The correlation between CFR and MRR values from both methods was significant but weak, suggesting that while both methods provide useful information, continuous thermodilution is generally more reliable for assessments.

Temporary rapid ventricular pacing (TRVP) is required during transcatheter aortic valve implantation (TAVI) in order to reduce cardiac output and to facilitate balloon aortic valvuloplasty, prosthesis deployment, and post-deployment balloon dilation. The two most frequently used TRVP techniques are right endocardial (RE)-TRVP and retrograde left endocardial temporary rapid ventricular pacing (RLE)-TRVP. The first one could be responsible for cardiac tamponade, one of the most serious procedural complications during TAVI, while the second one could often be unsuccessful.

Premature ventricular beats (PVBs) are recorded in a sizeable proportion of athletes during pre-participation screening, especially if the evaluation includes both resting and exercise ECG. While in the majority of cases no underlying heart disease is present, in others PVBs may be the sign of a condition at risk of sudden cardiac death, including cardiomyopathies, congenital, coronary artery, heart valves and ion channels diseases. In this expert opinion document of the Italian Society of Sports Cardiology, we propose a multiparametric interpretation approach to PVBs in athletes and a stepwise diagnostic algorithm.

Article Synopsis
  • The study investigates the best timing for performing percutaneous coronary interventions (PCI) in patients undergoing transcatheter aortic valve implantation (TAVI), a procedure for severe aortic stenosis with existing coronary artery disease (CAD).
  • An analysis of 1,603 patients from the REVASC-TAVI registry shows that performing PCI after TAVI leads to better 2-year clinical outcomes, with significantly lower rates of all-cause death and major complications compared to PCI before or concurrently with TAVI.
  • The findings suggest that scheduling PCI after TAVI may be more beneficial, but further confirmation through randomized clinical trials is needed.
