ABSTRACT
INTRODUCTION AND OBJECTIVES: Impact of gender on long-term outcomes after transcatheter aortic valve implantation (TAVI) remains uncertain. We aimed to investigate gender-specific differences in TAVI and its impact on outcomes. METHODS: This analysis used data from the prospective Spanish TAVI registry, which included consecutive TAVI patients treated in 46 Spanish centers from 2009 to 2021. The primary endpoint was all-cause mortality at 12 months. Secondary endpoints included in-hospital and 30-day mortality and TAVI-related complications. Adjusted logistic and Cox regression analyses were performed. RESULTS: The study included 12 253 consecutive TAVI patients with a mean age of 81.2 ± 6.4 years. Women (53.9%) were older, and had a higher STS-PROM score (7.0 ± 7.0 vs 6.2 ± 6.7; P < .001) than men. Overall, the TAVI-related complication rate was similar between women and men, with specific gender-related complications. While women more frequently developed in-hospital vascular complications (13.6% vs 9.8%; P < .001) and cardiac tamponade (1.5% vs 0.6%; P = .009), men showed a higher incidence of permanent pacemaker implantation (14.5% vs 17.4%; P = .009). There was no difference in all-cause mortality either in hospital (3.6% vs 3.6%, adjusted odds ratio [OR], 1.01; 95% confidence interval [95%CI], 0.83-1.23; P = .902), at 30 days (4.2% vs 4.2%, adjusted OR, 0.90; 95%CI, 0.65-1.25; P = .564) or at 1 year (11% vs 13%, adjusted HR, 0.94; [0.80-1.11]; P = .60). CONCLUSIONS: women treated with TAVI are older and have more comorbidities than men, leading to distinct complications between genders. Nevertheless, all-cause mortality in the short-term and at 1-year was similar between men and women.
ABSTRACT
BACKGROUND: Spontaneous coronary artery dissection (SCAD) and Takotsubo syndrome (TTS) constitute two common causes of nonatherosclerotic acute cardiac syndrome particularly frequent in women. Currently, there is no information comparing long-term clinical outcomes in unselected patients with these conditions. METHODS: We compared the baseline characteristics, in-hospital outcomes, and the 12-month and long-term clinical outcomes of two large prospective registries on SCAD and TTS. RESULTS: A total of 289 SCAD and 150 TTS patients were included; 89% were women. TTS patients were older with a higher prevalence of cardiovascular risk factors. Precipitating triggers were more frequent in TTS patients, while emotional triggers and depressive disorders were more common in the SCAD group. Left ventricular ejection fraction was lower in TTS patients, but SCAD patients showed higher cardiac biomarkers. In-hospital events (43.3% vs. 5.2%, P <0.01) occurred more frequently in TTS patients. TTS patients also presented more frequent major adverse events at 12-month (14.7% vs. 7.1%, HR 5.3, 95% CI: 2.4-11.7, P <0.01) and long-term (median 36 vs. 31 months, P =0.41) follow-up (25.8% vs. 9.6%, HR 4.5, 95% CI: 2.5-8.2, P <0.01). Atrial fibrillation was also more frequent in TTS patients. Moreover, TTS patients presented a higher 12-month and long-term mortality (5.6% vs. 0.7%, P =0.01; and 12.6% vs. 0.7%, P <0.01) mainly driven by noncardiovascular deaths. CONCLUSION: Compared to SCAD, TTS patients are older and present more cardiovascular risk factors but less frequent depressive disorder or emotional triggers. TTS patients have a worse in-hospital, mid-term, and long-term prognosis with higher noncardiac mortality than SCAD patients.

AIMS: Spontaneous coronary artery dissection (SCAD) is a relatively infrequent cause of acute coronary syndrome. Clinical features, angiographic findings, management, and outcomes of SCAD patients who present reduced left ventricular ejection fraction (LVEF) remain unknown. METHODS AND RESULTS: The Spanish multicentre prospective SCAD registry (NCT03607981), included 389 consecutive patients with SCAD. In 348 of these patients, LVEF could be assessed by echocardiography during the index admission. Characteristics and outcomes of patients with preserved LVEF (LVEF ≥50%, n = 295, 85%) were compared with those with reduced LVEF (LVEF <50%, n = 53, 15%). Mean age was 54 years and 90% of patients in both groups were women. The most frequent clinical presentation in patients with reduced LVEF was ST-segment elevation myocardial infarction (STEMI) (62% vs. 36%, P < 0.001), especially anterior STEMI. Proximal coronary segment and multi-segment involvement were also significantly more frequent in these patients. No differences were found on initial revascularization between groups. Patients with reduced LVEF significantly received more often neurohormonal antagonist therapy, and less frequently aspirin. In-hospital events were more frequent in these patients (13% vs. 5%, P = 0.01), with higher rates of death, cardiogenic shock, ventricular arrhythmia, and stroke. During a median follow-up of 28 months, the occurrence of a combined adverse event did not statistically differ between the two groups (19% vs. 12%, P = 0.13). However, patients with reduced LVEF had higher mortality (9% vs. 0.7%, P < 0.001) and readmission rates for heart failure (HF) (4% vs. 0.3%, P = 0.01). CONCLUSION: Patients with SCAD and reduced LVEF show differences in clinical characteristics and angiographic findings compared with SCAD patients with preserved LVEF. Although these patients receive specific medications at discharge, they had higher mortality and readmission rates for HF during follow-up.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. Multivessel (MV) SCAD is a challenging clinical presentation that might be associated to a worse prognosis compared with patients with single-vessel (SV) involvement. METHODS: The Spanish multicentre nationwide prospective SCAD registry included 389 consecutive patients. Patients were classified, according to the number of affected vessels, in SV or MV SCAD. Major adverse events (MAE) were analyzed during hospital stay and major cardiac or cerebrovascular adverse events (MACCE) at long-term clinical follow-up. RESULTS: A total of 41 patients (10.5%) presented MV SCAD. These patients had more frequently a previous history of hypothyroidism (22% vs 11%, p = 0.04) and anxiety disorder (32% vs 16%, p = 0.01). MV SCAD patients presented more often as non-ST segment elevation myocardial infarction (73% vs 52%, p = 0.01) and showed less frequently type 1 angiographic lesions (12% vs 21%, p = 0.04). An impaired initial Thrombolysis In Myocardial Infarction (TIMI) flow 0-1 was less frequent (14% vs 29%, p < 0.01) in MV SCAD. In both groups, most patients were treated conservatively (71% vs 79%, p = NS). No differences were found regarding in-hospital MAE or MACCE at late follow-up (median 29 ± 11 months). However, the rate of stroke was higher in MV SCAD patients, both in-hospital (2.4% vs 0%, p < 0.01) and at follow-up (5.1% vs 0.6%, p = 0.01). CONCLUSIONS: Patients with MV SCAD have some distinctive clinical and angiographic features. Although composite clinical outcomes, in-hospital and at long-term follow-up, were similar to those seen in patients with SV SCAD, stroke rate was significantly higher in patients with MV SCAD.

Spontaneous coronary artery dissection (SCAD) is a rare but increasingly recognized cause of acute myocardial infarction. Coronary angiography remains the best diagnostic tool; however, clinical suspicion and experience is required to interpret angiographic findings. This study sought to assess the clinical implications of the "broken line" (BKL) angiographic pattern in a large, nationwide, cohort of patients with SCAD. The Spanish SCAD registry (NCT03607981) prospectively enrolled consecutive patients with SCAD. All angiograms were centrally analyzed and the BKL pattern was systematically assessed. The BKL angiographic pattern was found in 64 of 389 patients (16%). Patients with the BKL appearance were more frequently female (97 vs 87%, p <0.05), presented more often as intramural hematoma (83 vs 58%, p <0.001), had longer lesions (47 ± 29 vs 36 ± 22 mm, p <0.01), and had severe tortuosity (25 vs 10%, p <0.01) but showed better initial coronary flow (thrombolysis in myocardial infarction flow 2.6 ± 0.8 vs 2.1 ± 1.2, p <0.01). Patients with BKL received more frequently conservative medical management (91 vs 76%, p <0.01). At late clinical follow-up (median 29 months, interquartile range 17 to 38) predefined adverse events (death, myocardial infarction, revascularization, recurrent SCAD, or stroke) occurred less frequently (3.5 vs 15%, p <0.05) in patients with the BKL appearance. The better clinical outcomes of patients in the BKL group persisted after adjusting for potential confounders (adjusted hazard ratio 0.2, 95% confidence interval 0.1 to 0.9, p <0.05). In conclusion, patients with SCAD presenting the BKL angiographic pattern are more frequently female and present more often as intramural hematoma with longer lesions and severe vessel tortuosity but have better coronary flow. Patients with the BKL morphology have a favorable prognosis (NCT03607981).

OBJECTIVE: Spontaneous coronary artery dissection (SCAD) is an infrequent cause of acute coronary syndrome. Our aim was to assess adverse events at follow-up from a nationwide prospective cohort. METHODS: The Spanish Registry on SCAD (SR-SCAD) included patients from 34 hospitals. All coronary angiograms were analysed by two experts. Those cases with doubts regarding the diagnosis of SCAD were excluded. The angiographic SCAD classification by Saw et al was followed. Major adverse cardiovascular and cerebrovascular event (MACCE) was predefined as composite of death, myocardial infarction, unplanned revascularisation, SCAD recurrence or stroke. All events were assigned by a Clinical Events Committee. RESULTS: After corelab evaluation, 389 patients were included. Most patients were women (88%); median age 53 years (IQR 47-60). Most patients presented as non-ST-segment-elevation myocardial infarction (54%). A type 2 intramural haematoma (IMH) was the most frequent angiographic pattern (61%). A conservative initial management was selected in 78% of patients. At a median time of follow-up of 29 months (IQR 17-38), 46 patients (13%) presented MACCE, mainly driven by reinfarctions (7.6%) and unplanned revascularisations (6.2%). Previous history of hypothyroidism (HR 3.79; p<0.001), proximal vessel involvement (HR 2.69; p=0.009), type 2 IMH (HR 2.12; p=0.037) and dual antiplatelet therapy (DAPT) at discharge (HR 2.18; p=0.042) were independent predictors of MACCE. CONCLUSIONS: In this large prospective cohort of patients with SCAD, prognosis was overall favourable, with events mainly driven by reinfarctions or unplanned revascularisations. History of hypothyroidism, proximal vessel involvement, type 2 IMH and DAPT at discharge were associated with MACCE. TRIAL REGISTRATION NUMBER: NCT03607981.

Spontaneous coronary artery dissection (SCAD) is a relatively rare but well-known cause of acute coronary syndrome in women. The role of sexual hormones has been related to the pathophysiology of SCAD. However, clinical features, angiographic findings, management and outcomes of SCAD women in relation to menopause status remain unknown. The Spanish multicenter prospective SCAD registry (NCT03607981), included 318 consecutive patients with SCAD. All coronary angiograms were analyzed in a centralized Corelab. In this substudy, 245 women were classified according to their menopause state (pre-menopausal and post-menopausal). In-hospital outcomes were analyzed: 148 patients (60.4%) were post-menopausal. These patients were older (57 [52 to 66] vs 49 [44 to 54] years, p <0.01) and had more often hypertension (49% vs 27%, p <0.01) and dyslipidemia (46% vs 25%, p <0.01). Post-menopausal women showed more often previous history of acute coronary syndrome, including previous SCAD (9% vs 3%, pâ¯=â¯0.046), and presented less frequently as ST-segment elevation myocardial infarction on admission, compared with premenopausal women (34% vs 49%, pâ¯=â¯0.014). On the other hand, premenopausal women showed more often proximal and multisegment involvement (24% vs 7%, and 32% vs 18%, respectively, both p <0.01). Post-menopausal women were more often managed conservatively (85% vs 71%, p <0.01) and presented less frequently left ventricular dysfunction (both, p <0.01). There were no differences between groups in terms of in-hospital stay or mortality, new acute myocardial infarction, unplanned coronary angiography or heart failure. In conclusion, post-menopausal women with SCAD show different clinical and angiographic characteristics compared with pre-menopausal SCAD patients. Initial treatment strategy was different between groups, though in-hospital outcomes did not significantly differ (NCT03607981).

INTRODUCTION AND OBJECTIVES: Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome. The characteristics and in-hospital clinical course of patients with SCAD in Spain remain unknown. METHODS: We present data from consecutive patients included in the national prospective SCAD registry. Angiographic analysis was performed in a centralized core laboratory. RESULTS: Between June 2015 and April 2019, we included 318 patients with SCAD (358 lesions) from 31 centers. Median age was 53 years, and 88% were women. The most frequent presentation was non-ST-segment elevation acute myocardial infarction (53%). The most frequently involved artery was the left anterior descending coronary artery (44%), predominantly affecting the distal segments (39%) and secondary branches (54%). Most lesions (62%) appeared on angiography as intramural hematoma, without double lumen. Conservative management was selected as the initial approach in most patients (78%). During the index admission, 6% of patients had a major adverse event and 4 patients (1.3%) died. Independent predictors of adverse events were initial management with percutaneous coronary intervention (OR, 5.97; P=.004) and angiographic presentation as intramural hematoma (OR, 4.96; P=.028). CONCLUSIONS: In Spain, SCAD affects mainly middle-aged women. In most patients, the initial management strategy was conservative with excellent in-hospital survival. Initial management with percutaneous coronary intervention and angiographic presentation as intramural hematoma were related to the presence of in-hospital adverse events.

The aim of this study is to propose national diagnostic reference levels (DRL) for updating in the field of interventional cardiology and to include technical details to help plan optimization. Medical physics experts and interventional cardiologists from 14 hospitals provided patient dose indicators from coronary angiography and percutaneous coronary interventions. Information about X-ray system dose settings and image quality was also provided. The dose values from 30,024 procedures and 26 interventional laboratories were recorded. The national DRLs proposed for coronary angiography and percutaneous coronary interventions were respectively 39 and 78 Gy·cm2 for air kerma area product (PKA), 530 and 1300 mGy for air kerma at reference point (Ka,r), 6.7 and 15 min of fluoroscopy time and 760 and 1300 cine images. 36% of the KAP meters required correction factors from 10 to 35%. The dose management systems should allow these corrections to be included automatically. The dose per image in cine in reference conditions differed in a factor of 5.5. Including X-ray system dose settings in the methodology provides an insight into the differences between hospitals. The DRLs proposed for Spain in this work were similar to those proposed in the last European survey. The poor correlation between X-ray systems dose settings and patient dose indicators highlights that other factors such as operation protocols and complexity may have more impact in patient dose indicators, which allows a wide margin for optimization. Dose reduction technology together with appropriate training programs will be determinant in the future reduction of patient dose indicators.
