RESUMEN
BACKGROUND: Preoperative systemic inflammation and nutritional status have been shown to affect prognosis in patients undergoing transcatheter aortic valve implantation (TAVI). In this study, we investigated the effect of the Naples Prognostic Score (NPS), which consists of four different parameters including these two components on short- and long-term prognosis in patients undergoing TAVI. METHODS: In 343 patients (mean age 78.1â±â8.4 years, 51.3% female) who underwent TAVI, the NPS score was calculated from the blood tests obtained before the procedure and the study population was divided into three according to the NPS value: those with 0 and 1 were divided into Group-1, those with 2 into Group-2, and those with 3 and 4 into Group-3. The relationship between NPS group and in-hospital adverse events and long-term survival was evaluated. RESULTS: Systolic pulmonary artery pressure, STS score, presence of chronic lung disease and being in NPS Group-3 [adjusted odds ratio (adjOR): 3.93, 95% confidence interval (CI) (1.02-15.17), P â=â0.047] were found to be independent predictors of in-hospital mortality. According to the multivariate Cox-regression model, both Group-2 NPS [adjusted hazard ratio (adjHR): 4.81, 95% CI (1.09-21.14), P â=â0.037] and Group-3 NPS [adjHR: 10.1, 95% CI (2.31-43.36), P â=â0.002] was an independent predictor of 2-year all-cause mortality after TAVI. There was no significant difference in perioperative adverse events between the groups except for postprocedural acute kidney injury. According to receiver-operating characteristic analysis, the optimal predictive value of NPS for in-hospital and long-term mortality was 2.5. CONCLUSION: In patients who will be candidates for TAVI, NPS is a simple and effective tool for determining both short- and long-term prognosis.

BACKGROUND: Preoperative left ventricular (LV) ejection fraction (PreLVEF) and preoperative LV end-systolic diameter (PreESD) are known predictors for postoperative LV dysfunction after mitral valve repair (MVR). Fragmented QRS (fQRS) evaluated in 12-derivation electrocardiography has widely been accepted as a sign of myocardial fibrosis. In the present study, we aimed to evaluate the relationship between fQRS in preoperative 12lead electrocardiography (ECG) and postoperative LV dysfunction that develop after MVR in patients with severe primary mitral regurgitation (MR) due to mitral valve prolapse (MVP). METHODS: From 2019 to 2022, 49 patients who had undergone successful MVR surgery for severeMR caused by MVP were enrolled in the study. The preoperative and postoperative echocardiographic data were collected retrospectively. We analyzed the demographic, echocardiographic, operative and postoperative parameters to assess the relationship between fQRS and early postoperative LV dysfunction, defined as an LVEF<60%. RESULTS: PreLVEF of all patients were ≥ %65. A total of 22 patients had fQRS (44.9%) and postoperative LV dysfunction was found to be 36.7%. A significantly higher rate of fQRS was observed in the group with postoperative LV dysfunction compared to the group without (12 (66.7%) vs 10 (32.3%), p: 0.036). In multivariate analysis for fQRS, PreESD, preoperative pulmonary artery systolic pressure (PrePASP), preoperative atrial fibrillation (PreAF), and male gender, only fQRS was found to be a significant predictor of postoperative LV dysfunction (p: 0.003, OR: 4.28, 95% CI (1.15-15.96). CONCLUSION: fQRS was found to be a predictor of postoperative LV dysfunction in the early period after MVR. fQRS may be a readily available and cost-effective test that can be used in clinical practice to predict postoperative LV dysfunction in patients undergoing MVR.

BACKGROUND: Pulmonary hypertension (PH) and right ventricular dysfunction are poor prognostic predictors in patients underwent transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS). AIMS: The prognostic impact of the main pulmonary artery/ascending aorta diameter ratio (MPA/AOr), measured simply by computed-tomographic angiography (CTA), was investigated in this patient group. METHODS: A total of 374 retrospectively evaluated patients (mean age 78.1 ± 8.4 years, 192 [51.3%] females) who underwent TAVI for severe AS were included. MPA/AOr was measured on preprocedural CTA in all patients and the effect of this measurement on the presence of PH, in-hospital and 2-year-overall long-term mortality was investigated. RESULTS: The presence of PH was defined as a systolic pulmonary artery pressure (sPAP) >42 mmHg measured by echocardiography. According to multivariate-logistic-regression analysis, MPA/AOr (adjusted [Adj] odds ratio [OR]: 1.188, confidence interval [CI] 95% [1.002-1.410], p = 0.048), tricuspid annular plane systolic excursion (TAPSE) (adj OR:0.736, CI 95% [0.663-0.816], p < 0.001) and left atrial diameter (adj OR:1.051, CI 95% [1.007-1.098], p = 0.024) were identified as independent predictors of PH. In addition, a statistically significant correlation was found between MPA/AOr and TAPSE (r: -0.283, p < 0.001). Furthermore, MPA/AOr was found to be an independent predictor of both in-hospital (adj OR:1.434, CI 95% [1.093-1.881], p = 0.009) and 2-year long-term (adj OR:1.518, CI 95% [1.243-1.853], p < 0.001) mortality in multivariate analysis including TAPSE, STS score and sPAP. In the 2-year Kaplan-Meier survival probability analysis, an MPA/AOr >0.86 was found to have a hazard ratio of 3.697 (95% CI: 2.341-5.840), with a log-rank p < 0.001. CONCLUSION: MPA/AOr, which can be measured simply by CTA, may be useful as an indicator of the presence of PH and poor prognosis in patients planned for TAVI for severe AS.

The present study evaluated the prognostic significance of right ventricular-pulmonary arterial (RV-PA) coupling, assessed by the tricuspid annular plane systolic excursion to systolic pulmonary artery pressure (TAPSE/sPAP) ratio, in patients undergoing transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS). This retrospective, single-center study involved 403 patients (mean age: 78.2 ± 8.4; 50.9% female). RV-PA coupling was categorized based on the pre-procedural TAPSE/sPAP ratio: severe uncoupling (≤0.32), moderate uncoupling (0.32-0.55), and normal coupling (>0.55). The study primary endpoints were in-hospital mortality and 2-year all-cause mortality. Multivariate logistic regression revealed that the TAPSE/sPAP ratio is an independent predictor of both in-hospital (adjusted OR: 0.61, 95% CI [0.44-0.84], P = .002) and 2-year mortality (adjusted OR: 0.69, 95% CI [0.56-0.85], P = .001). Severe uncoupling was strongly associated with increased 2-year mortality (adjusted OR: 3.92, 95% CI [1.67-9.20], P = .002). Our study establishes a significant association between reduced preoperative TAPSE/sPAP ratios and increased risks of both in-hospital and 2-year all-cause mortality in patients undergoing TAVI for severe AS. These results highlight the prognostic utility of evaluating RV-PA coupling. Incorporating this metric into preoperative risk stratification could potentially refine prognostic accuracy and inform clinical decision-making.
RESUMEN
OBJECTIVE: Although numerous studies have shown the protective effects of the well-developed coronary collaterals on left ventricular functions, the relationship between collateral grade and left ventricular end diastolic pressure has not been studied in chronic total occlusion patients. Also, there are conflicting data on the effect of collaterals on NT-proBNP levels. The aim of our study was to evaluate the relationship between coronary collateral circulation and left ventricular end diastolic pressure and NT-proBNP levels in chronic total occlusion patients. METHODS: Study group was retrospectively selected from the patients who had undergone coronary angiography at our hospital between June 2011 and March 2013. Clinical, biochemical, angiographic and hemodynamic data of 199 consecutive patients having at least one totally occluded major epicardial coronary artery were evaluated. Coronary collateral circulation was graded according to Rentrop classification. While Rentrop grade 3 was defined as well-developed, all the remaining collateral grades were regarded as poor collaterals. RESULTS: Overall 87 patients were found to have good collaterals and 112 patients had poor collaterals. There was no significant difference between the patients with well- or poorly developed coronary collaterals with regard to left ventricular end diastolic pressure (16.84 ± 5.40 mmHg vs 16.10 ± 6.09, respectively, p = 0,632) and log NT-proBNP (2.46 ± 0.58 vs 2.59 ± 0.76, respectively, p = 0,335). CONCLUSION: In patients with coronary chronic total occlusion even well-developed coronary collaterals are not capable of protecting the rise of left ventricular end diastolic pressure and NT-proBNP levels which are reliable markers of the left ventricular dysfunction.
RESUMEN
Variant angina (VA) is a clinical syndrome caused by spontaneous vasospasm of the epicardial coronary artery which is characterized by episodes of angina. Endothelial dysfunction and neurohormonal hyperactivity are important factors in pathogenesis of VA. Although patient prognosis is good, VA may be one of the reasons of sudden cardiac death (SCD) in case of persistent ST segment elevation and malignant arrhythmias. Therefore, early treatment of VA is crucial for prevention of malignant arrhythmias and SCD. In this case report we describe a case of VA presented with cardiogenic shock and malignant ventricular arrhythmia.
