Structural and Functional Characteristics of Mitral Paravalvular Leakage Identified by Multimodal Imaging and Their Implication on Clinical Presentation
Objective: Clinical presentation of patients with mitral paravalvular leakage (PVL) varies from asymptomatic to heart failure related with hemolytic anemia or pulmonary hypertension. We aimed to investigate the structural and functional characteristics of mitral PVL by multimodal imaging and their association with the severity of hemolysis and hemodynamic significance. Methods: A total of 74 patients with mitral PVL who underwent both cardiac computed tomography (CT) and echocardiography from March 2010 to December 2017 was investigated. Location and size of PVL, degree of left atrial (LA) calcification as measured by CT, and hemodynamic variables as measured by echocardiography were comprehensively analyzed. To investigate the degree of hemolysis and pulmonary hypertension, level of lactate dehydrogenase (LDH) and Doppler estimated systolic pulmonary artery pressure (SPAP) were used respectively. Results: Level of LDH was not related to PVL perimeter and was variable, especially in patients with a small PVL. However, it was positively correlated with mean mitral regurgitation velocity. Additionally, SPAP was significantly correlated with PVL perimeter and LA calcium score. In multivariable analysis, mean mitral regurgitation velocity was significantly correlated with levels of LDH (β = 0.345; p = 0.016), and PVL perimeter and LA calcium score were independently associated with SPAP (β = 0.249; p = 0.036 and β = 0.467; p < 0.001, respectively). Conclusions: Characteristics of mitral PVL and adjacent structures are associated with the severity of hemolysis and pulmonary hypertension. Evaluating the structural and functional characteristics of mitral PVL by complementary multimodal imaging would be important for understanding the clinical presentation and deciding optimal treatments for individual patients

Assessment of Sex Differences in 5-Year Clinical Outcomes Following Endovascular Revascularization for Peripheral Artery Disease.
Percutaneous transluminal angioplasty (PTA) is an effective treatment strategy for peripheral artery disease (PAD). Data are limiting regarding sex differences in patients with PAD who underwent PTA. We assessed the sex-related differences on 5-year clinical outcomes in patients with PAD who underwent PTA. We prospectively evaluated 765 patients with PAD (596 males and 169 females) who underwent PTA. We performed propensity score matching (PSM) analysis to adjust for any potential confounders. The primary endpoints were 5-year major adverse cardiac and cerebrovascular events (MACE) and major adverse lower-limb events (MALE) assessed by Kaplan-Meier curved analysis and log rank test. After PSM analysis, baseline clinical characteristics were similar in male and female patients. There was a trend toward a higher rate of major hematoma in female patients (6.1% vs. 0.9%, p = 0.066) and a lower rate of below the ankle amputation (24.7% vs. 16.5%, p = 0.097). During the 5-year clinical follow-up, male and female patients had similar rates of MACE (14.9% vs. 15.8%, log rank p = 0.838) and MALE (34.8% vs. 28.2%, log rank p = 0.264) as well as the individual endpoints. In subgroup analysis adjusted by PSM, female patients had a higher risk of bleeding complications in age ≥ 65 years, hypertension, diabetes mellitus, chronic kidney disease, and in the non-critical limb ischemia patients. Of patients with preserved renal function, female patients had a higher risk of MALE as compared to males. In conclusion, female patients with PAD who underwent PTA showed similar 5-year MACE and MALE compared with male patients
